How to Avoid the Slurry Pump From Being Burnt Out?

How to avoid the slurry pump from being burnt out?

1. If the head of the submerged slurry pump is too low or the head is higher than the actual requirements, it will cause a large flow and a rise in current. At this time, you can close the outlet valve to increase the resistance to control the current.

2. Water cooling is generally used to dissipate heat. If the motor leaks out of the water without water cooling, the temperature of the motor will rise, which will easily cause the motor to burn out.

3. If you deliver hot water within 80℃, you must use a hot water pump, and use tap water for cooling, otherwise the motor will burn out because the medium temperature is too high.

4. If there is no corresponding leak sensor, the submerged slurry pump should be regularly maintained and replaced with seals.

5. If the power cord is not properly contacted, it will also cause the motor to burn.

The circuit of the submerged slurry pump should be checked at all times to prevent it from being burnt out. In addition, if you suddenly feel a little hot on the outside during use, you can temporarily stop the machine at this time to cool down. In addition, please check more when wiring.

What is the reason for the broken shaft of the slurry pump?

For the slurry pump with broken shaft, the shaft size and strength calculation is carried out, and it is verified that its strength fully meets the requirements of working conditions, and the metallographic structure at the fracture also meets the requirements of heat treatment. However, if the shaft strength and metallographic structure meet the requirements, the shaft will be broken. After inspection, it was found that the bearings of the slurry pump were also damaged, and the front and rear sheaths had obvious friction marks and cracks.

Through analysis, the main reason for the broken shaft of the slurry pump is the damage to the bearing. The rotor moves back and forth under the action of axial force, and it rubs with the front and rear guard plates. The torque and bending stress on the bearing increase sharply, and it must bear the shaft at the same time. The shaft breaks due to impact.

Generally, the design margin of the shaft diameter of the slurry pump is sufficient. The reason for the broken shaft is mainly caused by external factors. When finding the cause of the broken shaft, in addition to the shaft itself, it is also important to consider the force of the shaft during the operation of the slurry pump. The actual situation, especially to detect whether the rotor and the front and rear sheaths have frictional collision.
