减压

Look for any signs of leaking between the gun and the unloader valve.

检查一下水枪和减压阀是否有泄漏的迹象。

Now my problem is low pressure (2800 psi) and surging peak pressure through the unloader valve.

现在我的问题是低压（2800psi ），通过减压器阀门实现最高压力。

Operating conditions affect the unloader because water quality, temperature, and time in bypass effect life and reliability.

操作条件，水质、温度、旁路温度会影响减压器生命周期和安全性。

Follow manufacturers instruction regarding the installation and adjustment of any unloader and safety relief valve you choose.

按照操作守则关于你所选择的减压器和安全卸压阀的安装和调节指示。

Another consideration is that the pressure-trapping unloader is more forgiving as it wears out.

另外一个考虑的问题是压力集及式减压器当其磨损时还可以工作。

Once an unloader is set it should never have to be adjusted again unless there are modifications done to the system.

减压器设置好之后，就不需要再进行调节，除非系统有所改变。

Any line restriction downstream of the unloader will change the Flow -actuated unloaders operating characteristics.

任何管路的限制将会改变流量式减压器的运行特性。

Second, there is a leak in the system that is allowing pressure to bleed off when the unloader is put in bypass.

第二，系统泄露，以至于在减压器安置在旁路时压力被释放。

The unloader is a valve that directs flow to either the nozzle or to bypass.

减压器是一个将水引流至喷嘴或旁路的阀门。

If the trapped pressure bleeds off the unloader will cycle, or hunt.

减压器补集到的压力会再循环，或叫做"猎取"。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.

粮食产品的运输费用与5月份相比没有变化，但却比去年同期高8％。
