Under the actual operating conditions, it is often necessary to match the specific lift of the existing centrifugal oil pump with the changing operating conditions under the condition that the revolutions remain unchanged. The problem invo

Cavitation, also called cavitation, is a mechanical phenomenon. Oil pump in the process of operation, when the flow of local pressure reduced to vaporization (saturated vapor pressure), the liquid begins to boil, generates a lot of bubbles

Gear oil pump is a common part in hydraulic system, which can be divided into stainless steel, cast steel and ordinary categories. The advantages of stainless steel gear oil pump are simple structure, small size, light weight, convenient m

High temperature oil pump is a kind of fluid machinery which can transform the mechanical energy of the prime mover into the mechanical energy of the fluid being transported. Generally speaking. If the fluid is liquid, it is called a pump;

One: pump cooling purpose ① Reduce the temperature of the bearing of the oil pump. (2) Take away a small amount of liquid leaking from the shaft seal, and export the friction heat. ③ Reduce the temperature of the sealing chamber, improve

One, the main basis for the selection of motor pump (1) According to the mechanical load nature and production process of motor starting, braking, operation, speed regulation and other requirements, select the motor type. (2) According to

In the process of using gear oil pump , the most common situation is the phenomenon of mechanical seal oil leakage, the following is to introduce its reasons and solutions: A. Leakage through the end face of the rotating ring and the stati

I. Heat conduction oil pump (including raw material pump and intermediate feed pump) Features: 1: stable flow 2: general head is higher 3: some raw materials viscosity is larger or contain solid particles 4: pump inlet temperature is gener

Requirements for stainless steel oil pumps in chemical installations (1) It must meet the requirements of flow, head, pressure, temperature, NPSH and other process parameters. (2) Must meet the requirements of medium characteristics: ① Fo

Selection of pump shaft seal Shaft seal is a sealing device to prevent leakage of pump shaft and shell. Commonly used shaft seal types are packing seal, mechanical seal and power seal. The shaft seal of the high temperature oil pump is usu
