The technical requirements of the self -suction pump before installation are very critical

1. Before installation, the self -suction pump must confirm that the length and height of the import pipeline cannot exceed the allowable suction range of the self -suction pump.

2. The import pipeline must not have air leakage. It should be guaranteed that it is a full -seal pipeline. Even small pores with large acupuncture eye will affect the self -suction ability of the self -suction pump.

3. The self -suction pump cannot be cheap when installation. Some users directly put the wooden bar base of the factory fixed self -suction pump with the self -suction pump on the ground when the newly purchased self -suction pump is used. The method is not desirable, which can easily cause the self -suction pump to vibrate and noise and make the self -suction pump mechanical failure. The correct method is to fix the pump base on a solid and flat platform or hard ground.

4. When installing the self -suction pump, try not to be fixed on the bracket welded with groove steel, because the slot steel is too small to contact the pump. At the same time as the tight base screw The concentricity of the base and a shaft is destroyed, so the self -suction pump installed on the groove steel bracket is the phenomenon that the vibration large coupling shaft is easily damaged.

     During the work, if the water pump is insufficient or the water is not out of water: First of all, you should consider whether the water inlet pipe is not strictly entered by the eye, cracks or joints, and observe it to find out the air. Some defects are very subtle, and it is difficult to find it directly to find it by the naked eye. It is often time -consuming but no result.
