Pumps are crucial fluid conveying equipment in the mining industry, essential for the normal operation of mines. During the operation of pumps in the mining industry, there are specific situations that require shutdown and maintenance to ensure the safe operation of the pumps and avoid greater losses. The following are several situations that require shutdown and maintenance.

1. Significant Performance Degradation

When the pump's operating performance significantly decreases, such as reduced flow rate or head, this may be due to internal wear, blockage, or component damage, requiring maintenance.

2. Abnormal Noise and Vibration

If abnormal noise and vibration occur during pump operation, it may indicate problems such as internal part wear, looseness, or blockage. In this case, the pump should be shut down and inspected immediately.

3. Increased Energy Consumption

If the pump's energy consumption increases significantly, it may indicate a decrease in pump efficiency or other problems. Shutdown and inspection are needed to check for wear, blockage, or electrical faults.

4. Overheating

If the pump's operating temperature is consistently too high, it may be due to bearing wear, poor lubrication, or motor failure. In this case, the pump should be shut down and inspected immediately to prevent equipment damage.

5. Leakage

Pump leakage, whether from the mechanical seal or flange connections, can lead to decreased efficiency and safety hazards. If leakage is detected, the pump should be shut down and repaired immediately.

6. Reaching Scheduled Maintenance Cycle

According to the pump's operating instructions and scheduled maintenance plan, regularly shut down the pump for inspection and maintenance. This ensures the pump is always in good operating condition and extends its service life.

7. Operational Malfunctions

During operation, if unexplained malfunctions or operational anomalies occur, such as failure to start or stop, the pump needs to be shut down immediately for inspection and troubleshooting before resuming operation.

8. Preventing Potential Risks

In addition to the specific manifestations above, pumps in the mining industry also require risk assessment based on operating environment and usage time. If there are potential safety risks or hazards, the pump should be shut down and inspected immediately.

In summary, during operation, pumps in the mining industry should be shut down and maintained immediately if performance degradation, abnormal noise and vibration, increased energy consumption, overheating, leakage, scheduled maintenance cycle, or operational malfunctions occur. This not only ensures the safe operation of the pump but also extends its service life.
