The reasons why pumps in the mining industry always draw in air is a complex issue involving multiple factors and aspects. Below is a detailed analysis of the causes of this phenomenon.

I. Pump Design Issues

Some pump designs may have flaws that make them susceptible to air intake during operation. For example, the inlet design of some pumps may be unreasonable, leading to easy bubble formation when the liquid flows.

II. Influence of Mining Environment Factors

The mining environment is complex and changeable, and pumps may be affected by various environmental factors during operation. For example, changes in temperature, pressure, and humidity can lead to a decrease in the pump's sealing performance, causing air intake. In addition, dust and particulate matter in the mine may also cause blockage or damage to the pump inlet, leading to air intake.

III. Improper Operation and Maintenance

Improper operation and maintenance are also important reasons for pump air intake. For example, failure to fully fill the pump with liquid when starting it up, or the presence of bubbles in the liquid, may lead to air intake during operation. In addition, if the pump is not maintained or inspected for a long time, it may cause wear or aging of the pump seals, resulting in air intake problems.

IV. Changes in Liquid Medium

The liquid medium used in mines may change due to changes in the mining process, such as changes in the temperature, viscosity, and chemical composition of the liquid. These changes may affect the pump's operating status and lead to air intake.

V. Solutions

In response to the above reasons, the following measures can be taken to solve the problem of pump air intake:

1. Optimize the pump design, especially the inlet design, to reduce bubble formation.

2. Strengthen the monitoring and management of the mining environment to ensure the pump operates in a stable environment.

3. Improve the skill level of operators to ensure the correct operation and maintenance of the pump.

4. Monitor and adjust the liquid medium to ensure it meets the pump's operating requirements.

5. Regularly inspect and maintain the pump, and replace worn or aged seals in a timely manner.

In summary, the reasons why pumps in the mining industry always draw in air involve design, environment, operation, and maintenance aspects. To solve this problem, comprehensive analysis and treatment are needed from multiple perspectives.
