After cutting, keep the blades overlapped to a certain extent, and the degree of blade overlap will decrease with the addition of specific speed　　 There is also a vibration method to measure the vibration frequency of the pump, and the measurement is relatively simple. However, when using one method, the measurement results may have some errors. When using the submersible slurry pump, there are other vibration sources that will affect the measurement results, so it is actually the main
