IMO screw pump Reasons for non absorption, Screw pump Why not aspirate? Let me explain to you today.

When the screw pump is used to pump liquid with low liquid level, the phenomenon that the screw pump does not absorb liquid occasionally appears. However, because we do not know the principle of the screw pump, we do not know the reasons why the screw pump does not absorb liquid. In fact, the reasons why the screw pump does not absorb liquid are mainly as follows:

1. During each operation, the screw pump was not filled with water or the media transported by the tank, which led to the damage of the rubber sleeve of the screw pump due to dry grinding. This is one of the reasons why the screw pump does not absorb liquid. The solution is that the liquid from the tank imported by the pump should be transferred into the screw pump before use to maintain the smoothness of the screw pump. IMO screw pump

2. The suction height of the screw pump in the process of application has exceeded the allowable suction height of the screw pump within 5 meters. 5 meters refers to the medium similar to sewage. If it is a liquid with high viscosity, for example, mud, it is recommended to select a vertical screw pump or use various pneumatic diaphragm pumps to submerge into the liquid for use.

3. The voltage of the screw pump is 380V or above. After wiring, the screw pump motor was directly used without paying attention to check whether it was reversed. At this time, any two of the three power lines should be replaced.

4. The viscosity of the delivered medium is too high, for example, the lime milk and other media. When using the screw pump, it is necessary to use the screw pump in a reverse direction. If the reverse direction cannot be used, the vertical screw pump can only be used.
