Some users are using new devices Screw pump The reason why the screw pump fails to discharge liquid is unknown. Some users may even suspect that the quality of the screw pump is faulty. In fact, the newly purchased screw pump fails to discharge liquid. You may refer to the following methods to solve the problem of the newly purchased screw pump failing to discharge liquid one by one.

IMO screw pump Reasons for no liquid out:

1. Check whether the motor of the screw pump rotates reversely, and the phenomenon that the motor rotates reversely and the screw pump does not discharge liquid also occurs.

2. Whether the inlet and outlet directions of the screw pump are installed reversely. The new screw pump product imports upward and exports in front, while the old screw pump product imports upward and exports upward.

3. As the liquid level is lower than that of the screw pump, one of the reasons why the screw pump is not filled with liquid to exhaust air and the smooth rubber sleeve cannot discharge liquid.

4. Due to the high concentration and viscosity of the delivered liquid, the low liquid level may be the reason why the screw pump cannot discharge liquid because it is far away from the suction inlet of the screw pump. The solution is to be as close to the liquid as possible. If the viscosity is too high, the reverse flow method is used to make the medium flow into the pump body automatically.

5. The air leakage seal of the inlet pipe of the screw pump is not tight, which causes the atmosphere to be sucked into the pump body to make the screw pump always in the state of suction. This is also the reason why the screw pump cannot discharge liquid.

6. Whether the inlet pipe of the screw pump is too large or not is not configured according to the standard diameter of the screw pump, which is also the reason why the screw pump cannot discharge liquid. IMO agent

7. When stainless steel screw pump is used to transport corrosive liquid, whether the rubber sleeve selected is used to the chemical corrosiveness of this kind of medium. If the wrong rubber sleeve is selected, and the rubber sleeve splashes this kind of liquid, it will expand directly and cause the screw pump to not rotate at all, which is also the reason why the screw pump cannot discharge liquid.
