One psychological story: cigarettes
First man to buy cigarettes, tobacco 29 yuan, but he did not match, with the clerk said: "By the way it sent a box of matches." Clerk did not give.
Second man to buy cigarettes, tobacco 29 yuan, he also did not match, with the clerk said: "cheap dime of it." Finally, he used the hair to buy a box of matches.
(Internal gear pump.)
This is the simple psychological marginal effect. The first: the owner think they make money in a commodity, the other one did not make money. Money feeling index of 1. The second: the owner that two commodities are making money, making money index of 2. Of course, the psychological tendency to second. Again, this is also reflected in the buy one get one psychological tricks, customers do not think there is one thing to pay, they earned, they are actually psychological marginal effect at play.
(Centrifugal oil pump.)
Transform a way can often play an unexpected effect! Usually a lot of things in a different approach will be different results. Life on the road, improving mental models and ways of thinking is very important.

How to exclude gear pump failure
Gear pumps are generally used for engineering machinery of dirty work environment and general machine tool accuracy is not high, and hydraulic system that the pressure is not too high and the flow is large.
Gear pump advantages:
1) Simple structure, good manufacture ability and low cost.
2) Compared with other same type of pumps, the structure of gear pump is compact, the size is small .
3) Self-priming performance is good. Both in high and low speeds even in the case of the manual can be reliably achieved self-absorption.
4) Speed range is large. Due to the transmission and a gear portion of the pump are substantially in balance, will not produce a large inertial force at high speed.
5) The dirt in the oil of their work is not serious and difficult to bite.
Gear pump disadvantages:
1) Working pressure is low. The pressure on gear, axle and gear shaft is imbalance, the load in the radial direction is large, limiting the increase off its pressure. Gear pump is mainly used in low-voltage systems.
2) A lower volumetric efficiency. This is due to the leakage of a large end face of the gear pump.
3) Flow ripple, causing pressure pulsations, which lets pipes, valves and other pieces emerge vibration and great noise.

5. CB gear pump seal skeleton damage or seal skeleton falls off when install axle.
Remedies:
1. Remove dirt, so that the suction pipe flow, or switch capacity suitable filter.
2. Add a little oil in the joints or seals, if the noise is reduced, the joints can be tightened or replaced seals, oil return pipe mouth should below the surface of the oil, and the suction pipe to have a certain distance.
3. Adjustment of concentric, excluding abrasions.
4. Replace the entire training gear.
5. Check seal, when replace if damaged to prevent inhalation of air.
Pump rotation is not flexible or killed:
Causes:
1. Axial gap and radial clearance is too small.
2. Poor assembly, CB-type cover, and the concentricity of the shaft is not good, the long axis of the spring fastening feet long, the quality of needle sleeve is poor.
3. Pump and motor coupling concentricity is bad.
4. Impurities is inhaled in the oil pump body.
Remedies:
1. Repair related parts.
2. Reassemble according to the requirements.
3. Adjusted so that the different axes is not more than 0.2mm.
4. Prevent surrounding sand lime, iron and other objects of cooling water into the oil reservoir to keep the oil clean.

Thermal Oil Pump-Common Ways to Remove Breakdowns II
Thermal Oil Pump-Common Ways to Remove Breakdowns II
(2) Mechanical reasons
①If connection between pump and coupling, due to irregularities, cause vibration and noise. It’s required to revise the coupling.
②When the dirt in oil enter into the gear oil pump, the oil pump gears and other parts get wear, thus generating noise. It’s suggested to change oil, strengthen the filter, and disassemble the pump for cleaning; for the badly worn gear, the gear should be repaired or replaced.
③When pump severely damaged or worn parts will produce vibration and noise: like the gear tooth pitch error, bad connection of two gears, tooth surface roughness high, too small backlash, the contact area not in the two gear pitch circle location, etc. In this case, replace the gear or grinding the gear. Meanwhile, needle roller bearing cage damaged, the length of the shaft journal and needle wear, can also lead to poor bearing rotation, thus produces mechanical noise, in this situation, it’s suggested for an overhaul, replacement of needle bearings.
④Gear assembly axial gap is too small; sliding gear face contact between the front and rear cover, due to failure to remove the burr carefully before assembly, thus strained joints during operation, and cause a large leak inside and output flow is reduced; dirt entering the pump and wedging between the front and rear cover of the gap, strain the surface, resulting in high and low pressure chamber due to the occurrence of radial strain and communication trenches, so that the output flow is reduced.
The above situation should adopt the following measures to repair. Dismantling gear pumps, appropriately increase axial clearance gap; use grinding cover face and gear face in order to remove the burr (not chamfer) on the tooth; after grinding, end face of the unloading groove depth dimension will vary, thus width should be increased accordingly.

Thermal Oil Pump-Common Ways to Remove Breakdowns
Thermal Oil Pump-Common Ways to Remove Breakdowns
Currently, CB-B type gear pumps are widely used in the dump truck and construction machinery, now Honghai Pumps explains the common faults and exclusion methods as below, for reference only.
1. Reasons of vibration and noise, and exclusion methods.
(1) Intake air
①As for CB-B type gear pump, the pump body and both sides cover is hard seal direct contact, if the flatness of the contact surfaces do not meet requirements, the pump easily inhaled air at work; Similarly, between the pump cover and the cap, which is also direct contact, the air is easily penetrated; if the lid is plastic, due to its damage or deformation due to temperature changes, the air is easy penetrated caused by leaky seal.
To exclude this failure, the method is: when the flatness between the pump body and pump cover doesn’t meet the requirements specified, you can use emery to grind the plate back and forth by shape route, otherwise use grinding surface grinder to make flatness not more than 5 μm; for leakage between the cover and lid, it’s suggested to use an epoxy resin or other adhesive for sealing.
② Skeleton type sealing is generally used for the shaft seal. If the spring off, or the oil seal backward, or lips were strained, aging, all the above situations will make the rear end seal often in negative state , thus to intake air, a new seal should be replaced and the problem solved.
③ Not enough fuel in the tank, or the suction nozzle is not plugged in to the oil below the surface, the pump will draw air into the fuel tank and you should replenish oil to the oil marking; if the return pipe mouth exposed oil, sometimes due to the negative pressure within the system instantly leaving air anti-irrigation into the system, so the return line ports generally should be inserted into the oil below the surface.
④ Pump mounting position from the oil is too high, especially when the pump speed is reduced, because they can’t ensure the pump suction cavity caused by lack of the necessary degree of vacuum suction and thus intake air. You should adjust the relative height of the pump and the oil so that it meets the requirements.
⑤ Oil filter is clogged dirt or capacity is too small, resulting in an increase in the intake air suction resistance; in addition, into the larger diameter oil port may also be brought into air. At this point, washable filter, or select a larger capacity, and the export path appropriate filter. In this way, it not only can prevent the inhalation of air, but also prevent the generation of noise.
There are other reasons like mechanism reason, heating or output flow problem, we will explain in our coming article.

Detailed Instructions of Choosing Pumps Part II
Continue with Detailed Instructions of Choosing Pumps Part I.
5. After choosing the pump model, for water pump and the approximate physical and chemical medium pump, it’s required to adjust the performance table or performance curves according to the product catalog or samples, in order to check if the normal operating point falls within the pump priority area. Is the effective NPSH greater than the (NPSH)? Otherwise, adjust the geometric mounting height based on the NPSH?
Gear oil pump.
6. For the pump transporting the delivery viscosity greater than 20mm2 / s (or density greater than 1000kg / m3), take note to change the water performance curve to characteristic curve of the viscosity (or the density), in particular, on the suction performance and input power, take serious computing or correction.
7. To determine the number of units and spare pump rate:
As for the normal operation, usually one pump is enough, because a large pump is equal to two paralleled small pumps (refer to head, the same flow rate). Generally speaking, a large pump is more efficient than a small pump, so to speak with energy saving, it’s suggested to use a large pump rather than two Centrifugal Pump.
When the situation is as below, two paralleled pumps are suggested:
Large flow when a pump can’t reach this traffic;
When a large pump need for 50% spare rate, two smaller pumps will be better;
For some large pumps, the pump can be used in parallel operation of 70% flow requirements, there is no need of spare pump. When a pump overhaul, another pump still carry on producing 70% of transport.
Required 24 hours for continuous non-stop operation of the pump, should spare three pumps, one run, a backup, a flat repair.
8. Under normal circumstances, customers can submit their election pumps basic conditions, and we will determine the model or recommend better solution. If the institute has determined the pump model, we will configure according to the Institute configuration requirements.

Detailed Instructions of Choosing Pumps Part 1
According to the basic principles presented before and the basic conditions, the detailed instructions are as below:
1. According to the layout, terrain conditions, water conditions, operating conditions of the device, make sure to choose horizontal, vertical, or other types pump (pipeline, diving, liquid-type, non-clogging, self-priming, gear, etc.).
2. According to the nature of the liquid medium to determine if clear water pump, heat pump, oil pump, chemical pump/ corrosion resistant pump, trash pump or non-clog pump.
Note: When pump installed in explosive areas, based on the regional level of the explosion, the corresponding explosion-proof motors should be applied.
3. According to the flow, make sure to choose single suction pump or double suction pump; according to head level, choose single stage pump or multi stage pump, or high speed pump and low speed pump (air conditioning pump).
Take note that the efficiency of multi-stage pump is lower than that of single-stage pump, when both single-stage pump and multi-tage pumps can be used at the same time, the first choice is single-stage pump.
4. Choose the specific model of the pump
After choosing which series of Screw Pumps are used, you can according to the maximum flow rate (in the absence of the maximum flow rate is usually desirable to 1.1 times of the normal flow rate as the maximum flow rate), take an enlarged head 5% -10%, the balance of these two properties after the main parameters to determine the specific model or series on the type spectrum characteristic curve. Operation is as follows:
Using a pump characteristic curve, find the desired flow values on the horizontal axis, find the lift values on the vertical axis, up and to the right from the two values cited vertical or horizontal line, right on the intersection of two lines characteristic curves, the pump is the right choice, but this ideal situation is rare, usually run into the following two conditions:
The first: the intersection is above over the characteristic curve, which shows the flow meet the requirements, but the head is not enough, in this situation, if the head is almost the same, or a difference of about 5%, you can still choose this pump, while a lot of difference, it’s suggested to select larger head pump. Or try to reduce pipeline pressure loss.
The second: the intersection is at the bottom of the characteristic curve, when it’s inside of the characteristic curve trapezoidal range, you can choose this model, and then depending on difference of head, decide whether to cut the impeller diameter.
If the head difference is small, do not cut, if the head a big difference, according to the desired Q and H, based on their ns and cutting formula, cut impeller diameter, if the intersection does not fall within the scope of the fan trapezoid, to select small head pump. When selecting a pump, sometimes you have to consider the production process requirements to choose different shapes Q-H characteristic curve.

Honghai pump on industry
Chemical
Honghai pumps are used throughout the chemical processing industry, from refineries and gas processing plants to basic chemical plants to polymer processing to end use product manufacturing. The chemical industry encompasses such a broad range of fluids and processes, that just about every type of Honghai pump made is used in one application or another.
Abrasives
Because many fluids contain abrasive particles, like waste oil or pigments containing titanium dioxide, Honghai has developed a series of abrasive liquid pumps with hardened parts and behind-the-rotor seals to minimize wear and extend pump life. Hardened parts can also be applied to Universal Seal series internal gear pumps, affording the same level of protection.
Bio-diesel
Honghai positive displacement pumping solutions are used extensively in the Biodiesel industry for raw materials, processing, transfer, and terminals. Honghai pumps can be utilized for Biodiesel produced from vegetable oils, waste fryer oil, animal fats, or other sources.
The Universal Seal series is ideal for bulk transfer or rail / tanker loading and unloading. They may be used for feedstock or finished B100 biodiesel and glycerine.
The pumps are used for process applications, handling liquids such as methanol, caustic, sodium methoxide, and FAME (fatty acid methyl ester). Typically these pumps are 316SS, though some applications will allow for cast iron.
Lubrication pump.
Rotating equipment, like large compressors, gearboxes, turbines and engines, use Honghai General Purpose, High Speed Compact, Motor Speed and Spur Gear pumps for dedicated, powered lubrication. They are also used in plant-wide lubrication systems and machine tool coolant/lubrication applications.
Honghai offers OEM pumps that are mechanically driven by the equipment that the pump is lubricating. These include reversing pumps which only flow in one direction, through the filter, regardless of which direction the shaft rotates.
2015年1月21日星期三
Soaps and Detergents
Honghai internal gear pumps used in the soaps and detergents industry has been proven with years of practices.
As it’s known to all that the soap and detergent chemistry is a with special requirements for pumps because of it’s mixing kinds of chemicals or their own special recipes. Thus special and featured pumps are in demand in it’s production. Honghai Pumps Ltd has the ability to produce such special pumps, such as stainless steel pumps, internal gear pumps, external gear pumps and industrial gear lobe pump for detergents and soaps manufacturing, transportation, packing, and some sensitive fields.
Working principle of Honghai Detergents Pumps
Two gears in internal gear pump coming in and out so as to produce flow. While at the same time, two identical gears rotating against each other, one gear is driven by motor and drive the other gear. Both gears are supported by shaft with quality bearing.
Step one
As the gears come out of the mesh, they will create expanding volume on the inlet side of Honghai internal gear pump. And then, the liquids will flow into the chamber and will be trapped by the gear teeth when they rotate.
Step two
Liquids travel around the inner side of the casing in the pockets between the teeth and the casing - which doesn’t pass between the gears.
Step three
At last, the mesh of the gears forces liquids through the outlet under pressure. Because of the gears supported from both sides, the Honghai external gear pumps are quiet- running and are routinely used for high-pressure applications. With no overload bearing loads, the rotor shaft won’t deflect and cause earlier wearing.
Feel free to contact Honghai Pump Ltd, and you will find the proper solution for your detergent and soaps chemistry.
Soap applications handled by Honghai pumps include:

The way to choose material of chemical pumps
The corrosion is one of the most dangerous harm to chemical equipment all the time, a little carelessness will damage the equipment or cause accidents and disasters. According to statistics, 60% of damages are caused by corrosion, so it’s first to choose the material of pumps.
It’s a misconception that a lot of people think stainless steel is almighty. Now let’s talk about the point of choosing materials for chemical medium.
Oil pumps.
1, Sulfuric acid(H2SO4)is one of the most strong corrosive medium, and it’s widely used as industrial raw materials. Different temperature and concentrations have different corrosive, if the concentration is higher than 80%,temperature is lower than 80℃ cast iron is best, but it’s not appropriate to high speed flow Sulfuric acid and not suitable to make pump valve.
General stainless steel like SS304 (0Cr18Ni9) and SS316 (0Cr18Ni12Mo2Ti) are limited use to Sulfuric acid. So we often use high silicon cast iron (different processing) and high alloy stainless steel.
Fluorine plastic has good ability of corrosion resistance and fluorine pump is economical.
The pumps’ type is IHF fluorine plastic pump, PF (FS) centrifugal pump, CQB-F fluorine plastic magnetic pump.
2, Hydrochloric acid Most of metallic materials are not resistant to hydrochloric acid corrosion (include a lot of stainless steel materials).Molybdenum containing high silicon iron only use for the hydrochloric acid that temperature below 50centigrade concentration below 30%.On contrary, a lot of non-metallic materials have good ability of corrosion resistance, so lining rubber pumps and plastic pumps (polypropylene, fluorine plastic) are the best choose.
The pumps’ type are: IHF fluorine plastic pump, PF (FS) centrifugal pump, CQ fluorine plastic magnetic pump.
3, Nitrate acid General metals are damaged in nitrate acid quickly, tainless steel is widely used, it has good ability of corrosion resistance in normal temperature and all kinds of concentration. The ability of corrosion resistance of stainless steel containing molybdenum like SS316,SS316L are not better than SS304,SS321.We often use titanium and titanium alloy materials for high temperature nitrate acid.
Our pumps’ type are: DFL(W)H chemical pump, DFL(W)PH shielding chemical pump, DFCZ process pump, DFLZP self-priming chemical pump, IH chemical pump, CQB magnetic pump, the material is SS304.

Characteristics of Honghai Screw Pump
In this article, Honghai will explain the detailed characteristics of Honghai Screw Pump and it’s detailed opeartion.
Because Screw Pump has those basic characteristics of variable transport, strong self-priming ability, can be reversed, transporting liquids containing solid particles, linear relationship between flow and speed, whose quality must be ensured by uniform atomization through high-speed centrifugal atomizer in the spray-drying production line with constant stream feed solution.
Improper considerations of design and selection will cause big trouble in the future use, operation and maintenance, thus Honghai suggests that screw pumps should be chosen on the basis of actual operation needs in order to guarantee smooth production, lower maintenance and repairing costs.
1.1 Configuration of ooriginal manufacturer in Assembly line production is a small DC motor, whose speed is controlled by SCR through SCR conduction phase angle formed by chopping different voltages to control DC motor speed controller in order to establish an internal voltage negative feedback. The instrument display is actually a voltage analog, although there are fluctuations but does not affect the normal use. However, because the product is with dust, and the dust particles are hygroscopic and sticky. The small DC motor ventilation is realized through air from the end of the motor fan. In some working days, inside the motor, it can accumulate a lot of dust, as the dust is hygroscopic, which will cause the motor leakage, frequent damage to the SCR governor controller. Because of its viscosity, brush part will be cleaned once in a few days, or if the brush stuck in the brush holder, the result is that when the operator clearly see speed table or in the original position, in fact, fuel pump has been stopped, while the device temperature fluid transport in the absence of material up the string, even if the feed pump speed control to maximum, also to no avail. Resulting in material waste and the yield of the product decreases.
1.2 Structure of screw structure will not allow operation in the case of broken material, once occurred, rubber stator will be burn due to instantly high temperature generated by dry friction. In the workshop, the feeding material is directly from the bacteria filter, there is a distance, thus in actual operation, the actual operation relies on the experience of the operator. But the production process tube blockage and off are obviously difficult to avoid. So, it’s important to ensure that the screw pump doesn’t rotate in idle or dry running in order to avoid losses.

Asphalt pump
Asphalt pump
As for Asphalt applications, in general, there are 4 different fields, to be specific, they are producing, which is also called refining; distributing to terminals, mixing and asphalts stuffing.
According to our knowledge and experience, as for asphalt application, steel pumps can be used in the universal seal series of refining and distributing areas. In our production lines, we have YCB series stainless steel pump.
In Asphalt Plants, hot mix field use mainly cast iron pumps in the Jacketed Universal Seal Series, with either packing or mechanical seals.
The series of Asphalt Pump is electrically heated, which simples the process of providing heat to the food pump from remote areas or some required emulsions.
Honghai pumps regularly handle rubberized asphalt (polymer modified asphalt or PMA) made from both virgin polymer and recycled tires.
As for stuffing or filling asphalt, which requires special abrasion-resistant hardened spare parts. This part will slow down the operation speed and reduce the wearing. Thus the seal series is commonly optional.
Miscellaneous Other Honghai Pump applications for asphalt include:
Distributor Trucks to spread asphalt emulsions for seal coating and chip sealing applications
Pipe Lining, where liquid asphalt is used to line sewer pipe in-plant and in-place
Tar Kettles, or portable heat-and-spray units, for on-site roofing build-up, foundation sealing and crack filling
Asphaltic insulation in automotive and appliance manufacturing for sound deadening.
Honghai is exploring more and more applications. Sharing soon.

Basic Principles of Choosing Pumps
It’s suggested by Honghai Pumps Ltd that five basic factors should be in consideration on selecting the right pumps based on working process and drainage requirements. To be specific, they are the amount of liquid delivery, device head, fluid properties, piping layout and operation of operating conditions.
1. The flow is one of the important performance data in selecting a pump, which is directly related to production capacity and delivery capacity of the entire apparatus. Such as the Institute of Technology Design is able to calculate the general pump properly, minimum and maximum, in total three kinds of flow. When the pump is selected, based on the maximum flow rate, taking into account the normal flow, when there is no maximum flow rate, it’s suggested as the maximum flow rate is about 1.1 times of the the normal flow rate.
2. Pump head required in the device system is another important performance data in selecting pumps, generally use the enlarged 5% -10% margin to lift the selection.
3. The liquid nature of the liquid medium include names, physical properties, chemical properties and other properties, the physical properties of the temperature c density d, the viscosity u, the content of the medium diameter of solid particles and gases, etc., which involves the lift system, effective gas NPSH calculations and suitable food pump types: chemical properties, mainly referring to chemical and toxic liquid medium, is the choice of materials and the choice of what kind of pump shaft seal type important basis.
4. The piping layout condition refers to a device system liquid feed height liquid feed to the liquid-feeding distance, such as the suction side of the minimum level, the discharge side of the maximum liquid level and some data, and the specifications and the length of the pipe, the materials, pipe specifications, the number of etc., for the Department of comb head NPSH calculations and checking.
5. A lot of contents of the operation conditions, such as a liquid saturated steam power operation T P, the suction-side pressure PS (absolute), the discharge side of the container the pressure PZ, altitude, ambient temperature or continuous operation, the oil pump is a fixed position of the gap or may shift.
