Chemical ore multi-stage pumpIt is a kind of pump equipment commonly used in chemical industry, which is used to transport chemical liquid. In order to ensure its normal operation and prolong its service life, correct repair and maintenance are very important.

1. First of all, before performing repairs and maintenance, you must ensure that the power has been cut off and the system is in a stopped state.

2. During maintenance, carefully check all parts of the pump, including impellers, bearings, seals, etc. If there is any wear, crack or other damage, it should be replaced or repaired in time. In addition, attention should be paid to the impurities and dirt accumulated in the cleaning pump to keep the pump unblocked. Check the pipes and joints of the multi-stage pump to ensure that there is no looseness, and try to manually rotate the pump body to verify its flexibility. Then, inject an appropriate amount of bearing lubricating oil into the bearing body, and the oil level should be maintained at the center line of the oil mark to ensure the timely replacement or supplement of the lubricating oil.

In terms of maintenance, first check and replace the lubricating oil regularly. Lubricating oil is the key to maintain the normal operation of the pump. The appropriate lubricating oil should be selected according to the requirements of the user manual, and replaced and supplemented regularly. In addition, attention should be paid to the lubrication of the bearings and seals of the pump to ensure that they are in good working condition.

4. In the use of chemical ore multi-stage pump, but also pay attention to avoid overload operation and frequent start and stop, in order to reduce the wear of the pump. In addition, the working temperature and pressure of the pump should be checked regularly to ensure that it is operating within a safe range.

5. When the multi-stage pump is stopped, the gate valve and pressure gauge should be closed first, and then the motor should be stopped. The pump needs to change the lubricating oil after 100 hours in the first month of operation, and then change the oil every 500 hours of operation. In addition, we also need to adjust the packing gland frequently to ensure that the drip in the packing room is normal.

6. It is very important to check the wear of the shaft sleeve of the multi-stage pump regularly. Once the wear is large, it should be replaced in time. When using multi-stage pump in cold winter season, the drain plug at the lower part of the pump body should be unscrewed after parking, and the medium should be drained to prevent freezing and cracking. Finally, after starting the motor and confirming the normal operation of the multi-stage pump, the gate valve should be gradually opened, and the display of the outlet pressure gauge and the inlet vacuum gauge should be observed to ensure that the motor load is within the normal range.

To sum up, the correct repair and maintenance for the operation and life of the chemical mine multi-stage pump is very important, only regular maintenance, and take the correct maintenance measures, in order to ensure the normal operation of the pump, improve production efficiency, reduce the failure rate.
