What is the brief history of the application development of water pumps?

The water pump is a refrigeration system that uses the heat released by the cold condenser to heat the regulated environment. As far as the thermophysical process of the water pump system is concerned, from the point of view of working principle or thermodynamics, it is a special use type of refrige...

The reason for the water pump leakage?

1. Reasons for water pump leakage  　(1) When the water pump was installed, the water seal seat assembly was not installed in place, causing the water pump to continue to leak. Since there is a water ring on the pump shaft corresponding to the inspection hole, when the water seal leaks, the cooling ...

Are Positive Displacement Pumps Self-Priming?

In principle, all positive displacement pumpsVibrator Motors Manufacturers in China are self-priming. In particular, this includes rotary gear pumps (internal and external), lobe pumps, vane pumps and diaphragm pumps. A common feature of all positive displacement pumps is the use of close-tolerance ...

What is the performance index of the pump？

The performance of the pump, the performance parameters of the pump, and the performance of the pump. Which parameters are used to represent the performance of the pump? What is the flow rate of the pump? Flow refers to the volume or weight of the liquid delivered by the pump per unit time. Expresse...

How to maintain the pump?

1. The filler of the water pump shaft must be added in time after it is completely worn out. If the water pump continues to be used, it will leak air. The direct effect of this is that the energy consumption of the motor will increase, which will damage the impeller. 2. When the pump is in use, ther...
