用减压阀延长凝结水泵寿命

译文：
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。

In setting the mechanical pump drive pressure, the correct way is to drive the pressure higher than the back pressure 1-1.5kg/cm2 (15-20psig). In most cases this is correct. But sometimesReducing Valves to achieve the requirements of the pump displacement, the driving pressure is set too need to be slightly higher. Driving pressure is high, the downside is likely caused by wear and tear on the intake valve. If the driving pressure higher than the required value, the intake valve will cause serious wear and tear and have to replace the200P pressure reducing valve intake valve in advance. In this case, recommend the use of pressure reducing valve or pressure reducing valve stations. Valve will be driven not only allow the pressure to meet the pump displacement to maintain the set pressure, while the intake valve to protect against wear and tear. In addition, theFixed proportional type reducing valve application of space narrow, it is recommended to use a steam pipe with a valve station. In the process of pumping water pump, a steam pipe for the pump for the steam to provide a buffer for the pump. The whole device buffer gentle movements to reduce wear on valve.
