Parameters are given how to calculate the petrochemical pump lift

IH100-80-160 petrochemical pump speed 2900 capacity 27.8 head 32 NPSH (m) 4.3 how much suction head

With 20 degrees of water, saturated vapour pressure of 2.3 KPa, atmospheric pressure 100 KPa, density of 1000 kg/m3, g = 9.81, H = (100 -) 2.3 x - 4.3-9.8/1000/1000 5.6 H H '=' H 'for the inlet line loss, according to the 2 m, H = 3.6 m.

Since entering this century, petrochemical pump has been widely used in all walks of life, especially in requiring 100% without leakage, but also has the incomparable advantage, but compared with the ordinary centrifugal pump, pump station where there are still some to be improved:

Isolation of single side leakage set of higher material and manufacturing requirements. Such as improper selection of materials or manufacturing quality is poor, can not stand the inner and outer magnetic steel friction of sleeve is easy to wear and tear, and when they burst, transmission medium will overflow.

Because the material of sleeve wear resistance is poorer, usually so power station pumps are commonly used to transport medium containing no solid particles. When conveying medium containing solid particles, usually need to be in power station pump suction side and filter, and need regular cleaning filter.
