Pressure: the force produced by the pump on the unit area of the conveyed medium
Pressure: the force produced by the pump on the unit area of the conveyed medium
Inlet pressure: the pressure of the suction chamber of the pump
Outlet pressure: the pressure of the pump discharge chamber
Working pressure: difference between pump outlet pressure and inlet pressure
Gauge pressure: the pressure calculated from atmospheric pressure. When the measured system pressure is equal to the local atmospheric pressure at that time, the pointer of the pressure gauge points to zero. That is, the gauge pressure is zero
Absolute pressure: pressure calculated from vacuum
Vacuum degree: when the absolute pressure of the measured system is less than the atmospheric pressure, the difference between the atmospheric pressure and the absolute pressure of the system is called vacuum degree
?The pressure unit is pa, kpa, psi, bar, Mpa, kg. Generally, bar is used to represent 1bar=100Kpa 1bar=1kg 10bar=1Mpa 1bar ≈ 14.5psi 1Kpa=1000pa 1bar, which is about equal to a standard atmospheric pressure
