Causes of gear pump rotation jam.1. The axial clearance or radial clearance is too small. Re-adjust and repair.
2. There is dirt in the pump. Disassemble to remove foreign objects.
3. The assembly is incorrect. The machining datum plane of the two pin holes of the gear pump is not the assembly datum plane. If the pins are driven in first, and then the screws are tightened, the pump will not rotate. The correct method is to tighten the screws while turning the gear pump, and finally drill the pin holes and drive the pins.

The AY single two-stage centrifugal pump is modified and redesigned on the basis of the old Y-type oil pump series. So if you want to extend the service life of the AY single two-stage centrifugal pump, you must do a good job of daily maintenance and maintenance on the basis of correct use.

The CYZ self-priming centrifugal pump uses the impeller to pump out the liquid under the action of centrifugal force. The self-priming centrifugal pump of Hebei Shenghui Pump Co., Ltd. uses single-row radial ball bearings and injects calcium-based butter to ensure lubrication. There is a cooling chamber at the bottom of the bearing body of the pump, and there are sealing rings in the high and low pressure areas of the pump. When the pump wears out to a certain extent after long-term operation, the self-priming performance of the pump should be replaced.

Asphalt heat preservation pumps are made of ordinary materials and stainless steel materials. Asphalt pumps generally adopt a non-leakage full heat preservation jacket structure, and heat transfer oil, steam, hot water and other thermal media can be used to heat the pump according to the conditions of the site; its working principle It is still driven by double gear meshing. Because of the viscosity of the asphalt, the generator power is not enough to support the viscosity to run at a high speed.

The stainless steel gear pumps that we use daily are mainly divided into two types: with safety valve and without safety valve. Many customers do not know whether to choose with or without safety valve. Hebei Shenghui Pump Industry will give you a detailed explanation of the functions and benefits of stainless steel gear pumps with and without safety valves!

The working principle of the multi-stage centrifugal pump for mining is the same as that of the ground centrifugal pump. When the motor drives the impeller on the shaft to rotate at high speed, the liquid filled in the impeller will be thrown to the impeller from the center of the impeller along the flow path between the blades under the action of centrifugal force. Because the liquid is affected by the blades, the pressure and speed increase at the same time, and it is guided to the next-stage impeller through the flow passage of the guide shell. In this way, it flows through all the impellers and the guide shell one by one to further make the liquid Pressure energy increases. After stacking each impeller step by step, a certain head is obtained and the downhole liquid is lifted to the surface. This is the working principle of the stainless steel multi-stage pump.
