High-efficiency energy-saving multi-stage pumps are widely used in modern industry, agriculture, and daily life, but sometimes pipeline rupture problems may occur during their use. This phenomenon not only affects the normal operation of the pump but may also cause safety hazards. The following are the main reasons for pipeline rupture in high-efficiency energy-saving multi-stage pumps.

1. Poor material quality

If the quality of the pipe material does not meet the standard and there are defects, the pipe will rupture due to fatigue after long-term use. Therefore, selecting high-quality pipe materials is the key to preventing rupture.

2. Excessive operating pressure

Multi-stage pumps have high operating pressure. If the pipeline design or operation is improper, resulting in excessive pressure exceeding the pipe's tolerance, the pipe is prone to rupture. Therefore, it is crucial to reasonably design the pipeline system and ensure that the operating pressure is within the pipe's tolerance.

3. Corrosive action

The medium in the pipeline may corrode the pipe material, especially in media containing acids and alkalis, where the corrosive action is more significant. Long-term corrosion will cause the pipe wall to thin and eventually rupture. Selecting corrosion-resistant pipe materials or using anti-corrosion coatings is an effective method to reduce corrosion.

4. Vibration and fatigue

Multi-stage pumps may produce some vibration during operation. If these vibrations are not properly handled, such as adding damping devices, long-term vibration will cause fatigue damage to the pipeline, leading to rupture.

5. Improper installation

During pipeline installation, if the interface is improperly handled, the fixing is not firm, or there are stress concentrations, it may also cause the pipeline to rupture during operation. Therefore, correct installation and commissioning are important links in ensuring pipeline safety.

6. Insufficient maintenance

Pipelines that have been used for a long time without timely maintenance and inspection may lead to problems such as aging and wear, causing rupture. Regular maintenance and inspection can promptly identify and solve problems, preventing accidents.

In summary, there are various reasons for pipeline rupture in high-efficiency energy-saving multi-stage pumps, including material quality, operating pressure, corrosion, vibration and fatigue, improper installation, and insufficient maintenance. During use, the influence of these factors should be taken seriously, and corresponding preventive measures should be taken to ensure the safe operation of the pipeline system.
