What Are The Maintenance Methods Of Wear-resistant Slurry Pumps?

The maintenance method of wear-resistant slurry pumps is the key to ensuring their long-term stable operation and extending their service life.The following are some detailed maintenance methods. These methods combine information from multiple sources and summarize and organize:

1. Daily inspection and maintenance

1. Inspection of bearing and lubrication system

- Regular inspection of bearing lubrication: Ensure that the bearing is lubricated well and there are no overheating, abnormal noise, etc.If poor lubrication is found, the lubricating oil should be replaced in time.It is recommended to use clean lubricating oil and replace it according to the prescribed lubricating cycle. It is generally recommended to replace the lubricating oil after running for 800 hours.

- Check the oil level: Check whether the oil level in the bracket is suitable every day to ensure that the lubrication system works normally.

2. Inspection and replacement of seals

- Check the condition of seals: including shaft seals, filler boxes, etc. to ensure that they are intact and without leakage.If the seal is found to be damaged, it should be replaced in time to prevent media leakage from affecting the operation efficiency of the pump.

- Adjust the tightness of the filler: Adjust or replace the tightness of the filler at any time. Do not cause the shaft seal to leak slurry, and replace the shaft sleeve in time.

3. Inspection of impeller and pump body

- Check the wear of impeller: If the wear is serious, the impeller should be replaced in time.At the same time, pay attention to checking the balance of the impeller to ensure its smooth operation.

- Clean the inside of the pump body: Clean the inside of the pump body regularly to remove sediment and impurities inside the pump body, and keep the inside of the pump body clean.During the cleaning process, attention should be paid to avoid damaging the internal parts of the pump.

2. Maintenance of electrical system and transmission parts

1. Check the motor and electrical system

- Motor operating status: Check the motor's operating status to ensure that it runs smoothly, without overheating, and without odor.

- Electrical system wiring: Check the wiring and components of the electrical system to ensure that they are intact and have no short circuits or circuit breakers.If problems are found, they should be repaired or replaced in time.

2. Ensure the normal operation of the transmission part

- Coaxiality and coupling: Ensure the coaxiality between the motor and the pump, ensure that the elastic pad in the coupling is complete and correct, and should be replaced in time after damage.

- Bearing temperature: Check the bearing temperature frequently to ensure that the bearing temperature does not exceed 60-65℃ when the wear-resistant slurry pump is running, and the maximum does not exceed 75℃.

3. Prevention and maintenance measures

1. Prevent blockage and damage

- Prevent foreign objects from entering: prevent metal objects, objects exceeding the maximum allowable particles, and long fiber objects from entering the slurry pump to avoid blocking the runner or damaging the pump body.

- Set up a filter device: Place a suitable barrier in the pump tank to reduce the possibility of excessively large particles or long fiber materials entering the pump body and causing clogging.

2. Regular inspection and record

- Regular inspection: Regular inspection of the slurry pump, observe its operating status, and check the integrity and tightening of each component.During the inspection, you should pay attention to the pump's inlet and outlet pressure, flow rate and other parameters to ensure its normal operation.

- Record maintenance status: During the maintenance process, maintenance status should be recorded, including maintenance time, maintenance content, replacement of components, etc., for subsequent analysis and reference.

3. Management of backup pumps

- Regular rotation: The backup pump or pump in a stagnant state must be manually rotated 90 degrees per week to ensure uniform load on the shaft and prevent the shaft from bending or deforming.

- Backwash and restart: If the shutdown time is too long, please use backwash water to flush the residue in the pump and then restart.

4. Summary

The maintenance methods of wear-resistant slurry pumps involve many aspects, including daily inspection and maintenance, maintenance of electrical systems and transmission parts, prevention and maintenance measures, etc.Through the implementation of these methods, the long-term stable operation of the slurry pump and the service life can be ensured.At the same time, attention should be paid to recording maintenance conditions for easier subsequent analysis and reference.During maintenance, appropriate tools and equipment should be used to avoid damage to equipment or injury to personnel using inappropriate tools.
