In order to prevent damage to the pump must pump discharge pipe into the suction pipe installed between the safety valve.

为了防止泵的损坏，必须在泵的排出管到吸入管之间安装安全阀。

This is because the adjustment of the pump suction pipe and installation height, work volume, high cost of construction, and by the construction of environmental constraints, and only in the device when the parking or large maintenance be carried out; the same time, due to process conditions, the adjustment of the pump suction pipe and install a high degree of turn affect the follow-up process, with a knock-on effect.

这是因为调整泵的吸入管路及安装高度，工程量大、施工费用高，并且受施工环境的制约，只有在装置停车或大检修时才能进行；同时，由于工艺条件的限制，调整泵的吸入管路及安装高度又将影响后续工艺，具有连锁反应。

Sewage pump suction pipe and outlet pipe flow of not less than 0.7m / s, and should not be greater than 2.0m / s.

排污泵吸水管和出水管流速不应小于0.7m/s，并不宜大于2.0m/s。

In addition, the effects of value is the size of the suction pipe lift resistance loss, therefore, should adopt the shortest pipeline layout, and with as little as possible elbow, and other accessories, can also consider the appropriate allocation of some large-diameter pipe to reduce the flow rate within.

另外，影响计算值的大小是吸水管道的阻力损失扬程，因此，宜采用最短的管路布置，并尽量少装弯头等配件，也可考虑适当配大一些口径的水管，以减管内流速。
