在设定机械泵的驱动压力时，正确的方法是使驱动压力高于背压1-1.5kg/cm2（15-20psig）。这在大多数情况下是正确的。但有时为达到泵的要求排量，需要将驱动压力设得稍高一些。驱动压力高时，不利的一面是容易对进气阀造成磨损。如果驱动压力高于要求值，会对进气阀造成严重的磨损而不得不提前更换进气阀。 　　在这种情况下，建议使用减压阀或减压阀站。减压阀既可以允许将驱动压力维持在能够满足泵排量的设定压力，同时也可以保护进气阀不受磨损。另外，在应用空间较狭窄时，建议使用带集汽管的减压阀站。在泵泵水过程中，集汽管为泵供汽从而为泵提供了缓冲区。这个缓冲区使整个装置的动作柔和，减少对减压阀的磨损。

Setting mechanical pump driven by pressure, the correct way is to make the driving pressure higher than the back pressure 1-1.5kg/cm2 (15-20psig). This is in most cases is correct. But sometimes to meet the requirements of displacement pump needs to be the driving pressure was set slightly higher. Driving pressure is high, the downside is easy to wear and tear caused by the intake valve. If the driving pressure is higher than required value, would cause serious wear and tear of intake valve had to replace the intake valve in advance. In this case, it is recommended the use of pressure reducing valve or pressure reducing valve stations. Valve can either allow the pressure to maintain the drive to meet the pump displacement of set pressure, but also can protect the intake valve from wear and tear. In addition, the use of space narrow, it is recommended to use with a set of steam pipe valve stop. Pump water in the pump process, the set of steam pipes to pump steam supply pump so as to provide a buffer. The buffer zone so that the whole devices, gentle movements to reduce wear and tear on the valve.
