High-efficiency energy-saving multi-stage pumps are widely used in various industrial fields due to their high efficiency and stable performance. However, flange damage is sometimes encountered during use. The following is a detailed analysis of the causes of flange damage in high-efficiency energy-saving multi-stage pumps.

I. Operation and Maintenance Issues

Non-standard installation operations and maintenance management are common causes of flange damage. During installation, if the tightening force of the bolts is uneven or excessive, it may cause uneven stress on the flange surface, resulting in deformation or damage. In addition, regular inspection and maintenance after long-term operation are equally important. Neglecting regular inspection and maintenance of the flange may lead to damage due to aging and wear.

II. Environmental Factors

The humidity, temperature, and corrosive media in the working environment have a great impact on the durability of the flange. In harsh environments, flanges are prone to corrosion and wear, especially in environments containing corrosive media, where the rate of flange damage will be greatly accelerated.

III. Material Issues

The choice of flange material is directly related to its service life and corrosion resistance. If the selected material is of poor quality or unsuitable for the working environment, the flange is easily damaged. Therefore, when selecting flange materials, the working environment, medium properties, and expected service life must be considered.

IV. Pressure and Flow Issues

Pump operating pressure and flow fluctuations can also lead to flange damage. When the pump's operating pressure exceeds the flange's tolerance, or when large flow fluctuations increase the fluid impact force, the flange may be damaged. Therefore, ensuring that the pump's operating parameters are within a reasonable range is one of the important measures to prevent flange damage.

V. Design Defects

In some cases, the flange design itself may have defects, such as unreasonable structure, insufficient strength, etc. These design defects may also lead to flange damage during use. Therefore, in the initial design stage, the stress conditions and working environment of the flange should be fully considered to ensure that its structure is reasonable and its strength is sufficient.

In summary, the causes of flange damage in high-efficiency energy-saving multi-stage pumps involve multiple aspects, including operation and maintenance, environment, materials, pressure and flow, and design. To solve this problem, it is necessary to take measures from multiple aspects, including strengthening operation and maintenance management, improving the working environment, selecting appropriate materials, controlling pump operating parameters, and optimizing flange design.
