Before starting the stainless steel sewage pump shall carry out various protection testing, so as to put the stainless steel sewage pump sewage pump and put into application, usually with overload, leakage, phase protection, signal detection, the purpose is to prevent the pump because of over current, Water Leakage leakage caused the pump burned to endanger other equipment's normal operation and the safety of people. Here is an introduction to the importance of vibration signal detection.

When the stainless steel blades sewage pump is the impeller rotating around the impurities in the water pump out of balance, violent vibration will cause the pump in the pump, access the piezoelectric vibration sensor is to detect the vibration situation of submersible sewage pump, so as to understand whether the normal operation of sewage pump. The sensor is made up of springs, mass blocks, piezoelectric patches and pedestal. The sensor base is rigidly fixed to the bearing between the submersible pump motor and the pump, and it can feel the mechanical vibration of the pump.

When the sensor to withstand the vibration, the spring stiffness is quite large, and the mass is relatively small, it can be considered that the quality is very small, so the mass feelings and the same vibration sensor base, and by the inertial force and opposite direction of acceleration effect, this kind of mass, there is a proportional to the acceleration of the alternating force on the piezoelectric element. Due to the piezoelectric effect of a piezoelectric element, alternating charges are generated on the two surfaces of the piezoelectric element.

Besides, in order to detect the information of stainless steel sewage pump in real time, temperature sensors, vibration sensors, oil and water probes and float switches are selected, and the monitoring and protection of pumps and motors are realized through control circuits. Zhongxing water also hopes that users can realize that during the operation of submersible sewage pump, the detection signal of working condition is the information carrier reflecting the normal or abnormal state of pump operation, and the appropriate detection method is the important condition for finding fault information.
