Some Little Tips about the Oil Pump

How to ensure G mono pumps’ pressure The max output pressure of G mono pump is according to bushhing series Level1: the max working pressure is 0.6mpa Level2: the max working pressure is 1.2mpa Level4: the max working pressure is 2.4mpa Asphalt pump. The solutions of solving gear pump’s electric current too large and not working suddenly The fault phenomenon: electric current is too large The reasons of fault: a, output pressure is too high. b, the viscosity of medium is too large. c, assembly of shaft seal is wrong d, shaft or bearing is damaged. e, fault of electric motor Methods: a, check lower equipment and pipeline. b, check medium’s viscosity. c, round the gear by hand when the pump is not working, check whether the gear round smoothly. d, check electric motor. The reasons of three screw pumps doesn’t suck up oil 1.Screw and pump bush are damaged, repair or replacement spare parts. 2.Suction pipe line jams or air leakage, check the pipe line. 3.Motor is reversal or speed is lower, please change motor. 4.Valve is out of work, please adjust spring or repair valve and valve seat. The detailed introduction of high temperature thermal insulation lubrication pump This type of pump is used to asphalt mixing equipment that transfer or spray asphalt oil, this is ideal equipment to asphalt factory, it’s also appropriate to other high viscosity medium. Every models has two kinds of structure forms: one is motor connect pump with coupling (six stage motor), the other is motor connect pump with belt pulley (four stage motor) This type of pump applies to transfer the medium not including solid particle and has solidifiability under the normal temperature and temperature below 350 centigrade, like heavy oil, bitumen, glue resin, detergent and so on. It especially used for the condition that the medium required to keep heat in outdoor installation at cold region. If the pump’s material is stainless steel, it can transfer high viscosity and corrosive mediums.

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. Honghai pump.

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.

Asphalt pump installation notes

Asphalt pump installation notes Asphalt heat pump is according to certain way and principle in production and using, to ensure it can produce good value and contribution in the production practice. Asphalt heat pump shows good development and status in the industry, to meet the needs of the development of the industry. 1. asphalt pump is driven by motor, and it shall not be reversed. So before the asphalt heat pump running, we must first determine the direction to ensure the correct operation. 2 asphalt heat pump is strictly prohibited running without the media in the cargo transfer, so as not to damage the gear. 3 If the asphalt heat pump is new installed or down a few days later, please don’t start immediately. You should first to grout some asphalt into the insulation pump body, and don’t start the pump until the oil pump body heating and cooling. 4 If the pump transports high viscosity or containing particles and corrosive media, you should use some water or solvent to wash to prevent the obstruction, so as to avoid the starting difficulty. 5, In winter, you should prevent the fluid line and cracking. 6, If you found that there is seepage in the shaft when the asphalt heat pump in use process, you must processing or replace the oil seal in time. 7, If you found some abnormal situations in operation, you should immediately stop the operation and check the reasons and remedy of the trouble.
