Pumps are crucial fluid conveying equipment in the mining industry, but during actual operation, pump run-dry may occur. Pump run-dry not only affects its work efficiency but also increases the risk of equipment damage. Therefore, how to deal with this issue has become a focus of the industry.

I. Brief Description of Pump Run-Dry

Pump run-dry refers to the operation of a pump without or with insufficient medium, which can cause cavitation, increased noise, and increased temperature inside the pump, seriously affecting the normal operation of the pump.

II. Common Causes of Pump Run-Dry in the Mining Industry

1. Pipeline leakage: Loss of medium, resulting in insufficient pump suction.

2. Control system failure: Such as the failure of the automatic medium replenishment system.

3. Improper operation: Insufficient medium is injected during startup or the medium injection time is improper.

III. Countermeasures

1. Regular Inspection and Maintenance

(1) Regularly check whether the connections of pipelines, valves, etc., are tightened to prevent medium leakage.

(2) Regularly maintain the pump to ensure it is in good condition.

2. Optimize the Control System

(1) Use an intelligent control system to monitor the pump's operating status in real time.

(2) Set run-dry protection; when the pump runs dry, it automatically shuts down or adjusts operating parameters.

3. Standardized Operation

(1) Ensure that the pump is filled with medium before starting to avoid run-dry caused by insufficient medium.

(2) Operators should receive professional training and be familiar with the equipment's operating procedures and safety regulations.

4. Introduce an Early Warning Mechanism

(1) Use sensors to monitor the pump's operating status in real time and give timely warnings when abnormalities are detected.

(2) Establish contingency plans; once a run-dry phenomenon occurs, take measures to deal with it promptly.

5. Select Appropriate Pump Types and Configurations

(1) Select appropriate pump types based on the actual needs of the mining industry.

(2) Reasonably configure auxiliary equipment, such as check valves and safety valves, to improve system stability.

IV. Summary

Pumps in the mining industry should deal with run-dry phenomena by combining the characteristics of the equipment and actual needs and adopting a variety of measures comprehensively. From regular inspection and maintenance, optimization of the control system, standardized operation, introduction of an early warning mechanism to the selection of appropriate pump types and configurations, every link is crucial. Only in this way can the stable and efficient operation of pumps in the mining industry be ensured, providing strong support for mining production.
