在各种化学工业中作为药液泵和 油泵 使用的泵，约80%是离心泵。另一方面，输送的液体从各种浓度的酸、碱、有机溶剂等以及挥发性强的液化气，直到高粘度液体或热油，其性质涉及的范围很广，但都可作为牛顿流体来考虑。 为了输送这些性质的液体，泵结构上应当

The oil pump The primary problem of oil pumps used as process pumps for conveying oil in refinery and petrochemical installations is performance degradation caused by liquid viscosity. Therefore, the most used is not easy to cause performa

Role of oil pump The function of the oil pump is to inject the right amount of fuel into the combustion chamber at the right time in the right form according to the working condition of the diesel engine to form a mixture suitable for comb

Reverse oil pump characteristics reflect the pump in the oil pump working condition, hydraulic turbine (hydraulic turbine) working condition and braking (energy consumption) working condition of all the full characteristic curve, because o

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

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;

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

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

Sf50 steel is enough for oil pump bearings as far as non-corrosive conveying medium is concerned. But when the jacket and green silver impeller are used, corrosion resistant materials or at least rust resistant materials are often used to

Gear pump is a rotary positive displacement pump, it has the advantages of positive displacement pump and centrifugal pump. Gear pump moving parts less. No valve parts and complex flow channel, good suction performance, small hydraulic los
