  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。

Application to extend valve life condensate pump Driven mechanical pump set pressure, the correct way is to make the driving pressure higher than the back pressure 1-1.5kg/cm2 (15-20psig). In most cases this is correct. But sometimes in order to achieve the requirements of the pump displacement, the need will drive pressure was set slightly higher. Driving pressure is high, the downside is likely to cause wear and tear on the intake valve. If the driving pressure is higher than the required value, the intake valve will cause severe wear and tear and had to be replaced ahead of the intake valve. In this case, it is recommended to use pressure reducing valve or pressure reducing valve stations. Valve only allows the driver to maintain the pressure to meet the set pressure displacement pump, while the intake valve can also be protected from wear and tear. In addition, a narrow space in the application, it is recommended to use a steam pipe with a valve station. In the process of pumping water pump, a steam pipe to the pump for the steam to provide a buffer for the pump. The buffer so that the whole device, gentle movements, to reduce wear and tear on the valve.
