Gear pumps positioning and correction

Gear pumps positioning and correction, which means that the gear pump is placed on the basis according to the foundation's vertical and horizontal centerline in order to meet the requirements. During installation of the gear pump, for most small and medium gear pump, it will share a base with the motor. In installing, it all takes overall installation method, i.e., after completion of the above preparations, the pump and the motor frame and integrally with smooth to hang on to the base, and then look for the positive and leveling. For large gear pump, it is generally first positioning the hoisting machine and adjust the seat after a good central location and level of degree, and then pumps and motors lifting to the frame to adjust the level of the coupling shaft distance and so on. Elevation adjustment and Levelling 1) Elevation adjustment Measurement and elevation Benchmarks (commonly known as zero) of elevation relative (positive or negative) called the elevation. The elevation of the absolute elevation and relative elevation. The absolute elevation is at sea level zero, and the height difference of sea level, called the absolute elevation; relative elevation is a elevation benchmarks for zero point - when, with the benchmark height difference is called the relative elevation value. The project mainly by the relative elevation, said the habit of elevation. Elevation adjusting gear oil pump is intended to facilitate pump and pipeline connections, in general, its elevation to the center line of the shaft for measuring the t-point, calibration of the pump to the foundation level as measured on the basis of the reference, the measurement device communicating with the liquid level. For the more stringent requirements of the pump, its elevation adjustment is measured with a level. Gear pump elevation deviation should be allowed to meet the provisions of table 6 - 5. The large deviation can be adjusted through the temporary pad iron. The large deviation can be adjusted through the temporary pad iron. 2) Levelling Gear pump beginning to find the level of degree elevation can make looking after, but also at the same time, it is by adjusting the level of temporary horn to adjust its level degrees. Measure the level of precision gear pump adjustment application is 0.02mm / m level meter or accuracy of 0.05mm / m level meter, on the surface of the pump outlet flange or shaft.

Solution of entrap phenomenon of Gear Pump

Solution of entrap phenomenon of Gear Pump

As for gear pump , in order to work smoothly, the gear meshing of the coincidence degree must be greater than 1, so there are always two pairs of gears mesh at the same time, and some of the oil is trapped between two pairs of teeth surrounded by a closed cavity.

The close cavity started to decrease gradually as the gears rotate, then gradually increase. Closed chamber will reduce, which will extrude the trapped oil and cause high pressure, and then the oil will be extruded from the gap, resulting in heating oil, which will cause extra load for the spare parts; While at the same time, the closed cavity volume increases and caused a partial vacuum, so that the gas dissolved in oil separation, which causes a sudden formation. All of these above will cause a strong vibration and big noise, this is called entrap phenomenon.

The harm
When the gear oil pump radial unbalanced force is large, the shaft will be bended, and the tooth top contact with the casing, which will accelerate the bearing wear and reduced the bearing life.

The method of eliminating
The common method to eliminate the entrap phenomenon is to open the unloading groove on both sides of the cover plate, so that the closed cavity volume decreases by unloading groove and pressure oil cavity discharge on the left, the volume increases by the right side of the unloading groove and communicated with the oil absorption cavity.

Honghai will explain more info of using gear pumps and the related instructions. Keep focusing on our news and we will update soon.

Principle and Application of Honghai Stainless Steel Pump

Stainless steel pump is a gear pump, which has the property of acid-proof and wear-resistance. According to the design provided by the utility model, install the driving shaft and the driven shaft in the housing, install the gear in the active section of the mounting shaf, and fitting the opposite gear in engagement with the gear driven shaft, both gears forming a gear pair, material inlet and outlet are provided in the casing.

Its features are: ceramic plate will be set in the inner wall of the housing cavity. This system is able to improve the property of acid-proof and wear-resistance to the gear pump through change of the pump structure.

Stainless steel gear pump is commonly divided into different models like straight teeth gear pump, helical gear pump, and herringbone gear pump. As for tooth profile, there are generally involute tooth type and arcs type. Usually the small gear pump more adaots involute spur gears, and high temperature gear pumps often shifted gear.

In transporting of high viscosity, high-pressure melting polymer, it's suggested to take helical gear. Gear formed integrally with the shaft, its rigidity and higher reliability than a gear with a gear pump shaft is separately manufactured. As for foreign low pressure gear pump, the gear often use a square structure, i.e., the gear tooth width equal to the tip diameter. The use of high-viscosity gear pump high pressure applications tooth width less than the diameter of its addendum circle, which is to reduce the radial pressure receiving area of the gear, reducing gears, bearings load.

Stainless steel gear pump is a new type of transmission fluid machinery, has a simple structure, safe and reliable operation, easy maintenance, the liquid continuous uniform, stable pressure.
