Determination Of Centrifugal Pump Installation Height And Analysis Of Factors Affecting Suction

2 Change the installation height of pompa sanitary when conveying 80°C water. Solution: 1. The installation height of pump sanitary when conveying 20°C clean water. Given: Hs=5.7m Hf0-1=1.5m u12/2g≈0 The local atmospheric pressure is 9.81x104Pa, which is basically the same as the experimental conditions of sanitary beverage pump when it leaves the factory. Therefore, the installation height of sanitary food pumps is Hg=5.7-0-1.5=4.2m.
2 The installation height of small sanitary pump when conveying 80°C water When conveying 80°C water, the Hs value in sample stainless steel sanitary pump cannot be directly used to calculate the installation height. Hs should be converted according to the following formula, that is, Hs1=Hs+ Ha-10.33-Hu-0.24 Given Ha=9.81x104Pa≈10mH2O, it is found from the appendix that the saturated vapor pressure of water at 80°C is 47.4kPa. Hv=47.4x103 Pa=4.8
