Optimization strategies to extend the service life of centrifugal pump mechanical seals 二

4 Eliminate pump cavitation

For the problem of daily cavitation at the pump inlet, there are several ways to eliminate it: First, try to enhance the cavitation performance of the pump so that it can meet the corresponding requirements of the on-site device. The second is to select pump cavitation performance that matches the actual conditions of the field test device. The third is to adjust the working conditions during the on-site installation process to create favorable conditions for the pump to work and reduce the probability of cavitation.

5 Reduce pump vibration

The problem of pump vibration can be reduced from the following aspects: first, when designing the pump, strengthen the analysis of the sources of pump vibration, and take appropriate elimination measures to avoid vibration; second, during maintenance and assembly, strictly follow the Follow the procedures to avoid vibration caused by assembly problems; thirdly, when installing motors, bases and other auxiliary equipment on site, corresponding controls must also be done. Effectively eliminate vibrations caused by external factors.

6. Improve manufacturing accuracy

Regarding the problem of insufficient manufacturing accuracy. We should start from two aspects: first, do a good job in manufacturing process control, strictly follow the corresponding processes to process and manufacture pump parts, do a good job in quality control, and ensure processing accuracy; secondly, strengthen the inspection of pump parts, through sampling inspections, etc. With the help of high-precision equipment, the accuracy of pump components is inspected to avoid the use of parts with insufficient manufacturing accuracy in actual use, improve the overall manufacturing accuracy level, and meet usage requirements.
