Before using the slurry pump, a series of necessary inspections are required to ensure its proper operation and extend its service life. Here are some key check steps:

1. Check the equipment status:

1. Ensure that the slurry pump, pipes and valves are clean, dry, oil-free and leak-free.

2. Check whether the oil level in the bracket is suitable. The oil level should be near the oil level line and should not exceed 2mm.

3. Check whether the pump is operating abnormally, whether there is vibration or leakage. Once problems are found, they should be dealt with in time.

4. Check whether the support mechanism of the inlet and outlet pipe system is loose, whether the pump body is subject to support force, and the tightening of the pump on the basis.

2. Check the electrical connection:

Check whether the electrical connections of the slurry pump and its auxiliary equipment are firm, whether there is any leakage or short circuit, and whether the power supply voltage meets the requirements.

3. Check the properties of the fluid:

Check whether the working fluid meets the requirements, including whether the liquid concentration, temperature, pH is normal, and whether there are impurities or excessive impurities.

4. Check the rotation direction:

Test the rotation direction of the motor to ensure that it is consistent with the rotation direction specified by the pump. During testing, the motor should be tested separately, and not with the pump.

5. Check key components:

1. Check whether the bolts of each part of the pump are tight, especially anchor bolts.

2. Check whether the elastic pad in the coupling is complete and correct, and whether the belt is damaged, insufficient or moderately tight.

3. Check whether the rotation of the motor shaft and the pump are concentric and whether the pulleys are aligned.

4. Check whether the bearing oil in the bearing box is added to the position indicated by the oil mark.

6. Prepare to start:

1. Before starting the slurry pump, open the shaft sealing water (mechanical sealing is cooling water) to ensure that the water is clean and the water pressure is appropriate.

2. Open the pump inlet valve and close the pump outlet valve.

After completing the above inspection, you can start and operate the slurry pump. During use, it is also necessary to regularly check whether all components of the slurry pump are normal, such as whether there are foreign objects inside the pump body, whether the bearings and seals are normal, and whether the motor is operating normally. Through these necessary inspections and preparations, the safe and stable operation of the slurry pump can be ensured, production efficiency can be improved and equipment service life can be extended.
