卧式混流泵



When purchasing a mixed flow pump, you should pay attention to:

Motor grounding device inspection: For electric pumps that are coaxial with the water pump and the motor, the motor should be equipped with a grounding screw at an appropriate location and a grounding mark near the grounding screw; small submersible pumps should have reliable grounding devices and grounding wires. The grounding wire of the outgoing cable of the mixed flow pump should have an obvious grounding mark; this mark should not be easily worn away during the service life of the motor. This item is one of the important safety indicators of electric pumps.

The operation and running of the mixed flow pump should be stable, without abnormal vibration and noise, no obvious leakage at the oil seal, and the working temperature of the bearing should not exceed 75 ° C.

According to the required flow, head, shaft power, efficiency, necessary cavitation allowance (or suction stroke) and use conditions, determine the model of the mixed-flow pump initially, and select the pump with the same rating and required parameters

Check before starting the mixed flow pump:

Move the motor coupling by hand to check whether the rotation is flexible and whether there is a feeling of lightness, weight, uniformity or friction.

Check the bearings; check whether the lubricating oil (grease) is at the position indicated in the display window for the rolling bearings, and check whether the upper cooling water lubrication is ready for the rubber bearings.

Check whether the connecting bolts of all parts are tightened tightly and whether they are loose.

Inspect the water inlet and outlet flow channels and the inlet pool for any obstructions.
