由于吸液管道或者轴封的地方有泄漏会导致空气被吸入到单螺杆泵里面,这样单螺杆泵就会处于吸空气的状态,进口管道不能形成负压所以螺杆泵吸不上液体。处理方法是检查、修理管道,排除杂物,调整更换轴封。
Due to leakage in the suction pipe or shaft seal, the air will be sucked into the single screw pump, so the single screw pump will be in the state of suction air, and the inlet pipe can not form negative pressure, so the screw pump can not suck up the liquid. The treatment method is to check, repair the pipe, remove the sundries, and adjust the replacement shaft seal.

单螺杆泵电机反转也会导致螺杆泵吸不上液体的现象出现,调整电机的极性接头就可以了。
Single screw pump motor reverses can also lead to the phenomenon that the screw pump does not absorb liquid, and the adjustment of the polarity joint of the motor can be made.

抽吸的矿浆太干,或在半干状态下运转也是螺杆泵吸不上液体的原因,这种情况只能稀释或向进料口加入充足的矿浆。
If the pulp is too dry or running in half dry state, it is also the reason why the screw pump doesn't suck up the liquid. This situation can only dilute or add enough pulp to the feed port.

输送的液体粘度太高也会导致螺杆泵吸不上液体,如果是液体粘度太高的问题只能降低螺杆泵的转速然后提高液体的温度后使其粘度降低或者改用立式螺杆泵。
The viscosity of the conveying fluid is too high, which will cause the screw pump to not suck up the liquid. If the liquid viscosity is too high, it can only reduce the rotational speed of the screw pump, and then raise the viscosity of the liquid after lowering the temperature of the liquid, or change it to the vertical screw pump.

在使用一段时间的单螺杆泵吸不上液体很有可能是定子和转子损坏所致,检查更换新的定子或者转子就可以了。
The use of a single screw pump for some time is likely to be caused by damage to the stator and rotor, and it is possible to replace the new stator or rotor.

进出口管道上的阀门没有打开或开度不够,打开进出口阀门就可以了。
The valve on the import and export pipe is not open or open enough, and the valve will be open.

填料密封的单螺杆泵有可能是填料磨损、机械密封的螺杆泵有可能机械密封面损坏或磨损,压紧或更换填料,机械密封损坏更换新的机械密封就可以了。
The single screw pump with filler seal may be a screw pump with filler wear and mechanical seal. It is possible to damage or wear the mechanical seal surface, compress or replace the packing, and damage the mechanical seal to replace the new mechanical seal.
