The boiler feed water pump is used to deliver high temperature and high pressure water to the boiler steam drum of the boiler feed water system to maintain the normal operation of the boiler. Continuous water supply is essential for steam boilers, not only to avoid overheating, but also to avoid...

What is overload? What is overcurrent? What is overload? Every electrical device used in the power grid or in our daily life will have a rated power. When the power of the device is higher than the rated power, we call it overload. Likewise, we will call this protection over rated power overload...

About the balance hole of the impeller The balance hole (return port) is mainly to balance the axial force generated when the impeller is working. It reduces the wear of the bearing end face and the wear of the thrust plate. When the impeller rotates, the liquid filled in the impeller is removed...

(1) The impeller flow passage is blocked If part of the flow passage of the impeller is blocked, it will affect the work of the impeller and cause the outlet pressure to drop. Therefore, it is necessary to disassemble the pump to check and remove foreign objects. In order to prevent this problem...

Selection of Boiler Feed Pump Working conditions of boiler feed pump The boiler feed water pump is used to deliver high temperature and high pressure water to the boiler steam drum of the boiler feed water system to maintain the normal operation of the boiler. Continuous water supply is...

Pumps with long shafts are prone to lack of shaft stiffness, too much deflection, and poor straightness of the shaft system, resulting in friction between the moving parts (transmission shaft) and the static parts (sliding bearings or mouth rings), resulting in vibration. In addition, the pump...

Introduction of sewage pump Sewage pumps are used to transport sewage and untreated waste water (eg raw waste water). They are most commonly used in municipal wastewater treatment plants, but are also used in buildings and private homes that cannot be connected to municipal sewers due to the...

What is differential pressure and full differential pressure? Differential pressure Differential pressure usually refers to the pressure difference between two points of the valve in the pipeline, such as the pressure difference before and after the valve, the pressure difference on both sides...

Stainless steel not only rusts, but also corrodes Why does stainless steel also rust? When brown rust spots (spots) appear on the surface of stainless steel pipes, people are amazed: "Stainless steel does not rust, and if it rusts, it is not stainless steel, and there may be a problem with...
