High-corrosion-resistant and wear-resistant multi-stage pumps, as critical equipment widely used in industrial fields, their stable and reliable performance is crucial for the normal operation of the production process. However, water leakage sometimes occurs during use, which not only affects the pump's performance but may also cause bigger problems. The following is an analysis of the causes of water leakage in high-corrosion-resistant and wear-resistant multi-stage pumps.

I. Mechanical Seal Failure

The mechanical seal is one of the key components of the pump, and its failure is the main reason for water leakage in multi-stage pumps. This may be due to factors such as natural wear and tear from prolonged use, improper selection, or installation errors, causing the mechanical seal to become ineffective and leading to water leakage from the pump body.

II. Problems with the Pump Body or Pipe Connections

If the connection between the pump body and the pipe is not properly handled, such as loose fastening screws, aging sealing gaskets, or misaligned connecting flanges, it may cause water leakage at the connection. In addition, casting defects or long-term corrosion and wear of the pump body itself may also lead to water leakage.

III. Unreasonable Shaft Seal Design

Unreasonable shaft seal design or improper material selection may lead to water leakage at the shaft seal. For example, a shaft seal that is too tight or too loose may affect the sealing effect. In addition, the surface roughness or shape error of the shaft may also cause the shaft seal to fail.

IV. Medium Problems

Medium problems may also cause water leakage in multi-stage pumps. For example, excessively high or low medium temperatures, or excessive corrosiveness, may corrode or wear the pump material, leading to water leakage. In addition, impurities in the medium may also cause wear and tear on the mechanical seal or other components.

V. Improper Operation and Maintenance

Improper operation and maintenance are also one of the reasons for water leakage in multi-stage pumps. For example, unstable operation during pump start-up and shutdown, failure to perform regular maintenance according to regulations, or failure to replace wearing parts may lead to a decline in pump performance, thus causing water leakage problems.

In summary, the causes of water leakage in high-corrosion-resistant and wear-resistant multi-stage pumps involve multiple aspects, including mechanical seal failure, problems with the pump body or pipe connections, unreasonable shaft seal design, medium problems, and improper operation and maintenance. To solve this problem, comprehensive analysis and treatment are needed from multiple aspects to ensure the normal operation of the pump.
