Installation height Hg of centrifugal pump

The allowable suction vacuum height Hs refers to the maximum vacuum that can be reached by the pressure p1 at the pump inlet. The actual allowable suction vacuum height Hs value is not calculated according to the formula, but the value measured by the pump manufacturer. The value is attached to the pump sample for users to check. It should be noted that the Hs value given in the water pump sample is the value when clean water is used as the working medium, and the operating condition is 20℃ and the pressure is 1.013×105Pa. When the operating conditions and working medium are different, conversion is required. Water water pump manufactureru003c/pu003e
