Description

technical field [0001] The invention relates to a fully automatic water pump state monitoring and fault diagnosis system. Background technique [0002] With the rapid development of the national economy, various large, medium and small water pumps have a wide range of application markets in water conservancy projects, municipal engineering, industry and agriculture, and play an important role in them. During the operation of the pump, different influencing factors such as mechanical factors, hydraulic factors, and electromagnetic factors will cause the vibration, swing and displacement of the pump shaft. The emergence of vibration, swing and displacement problems will cause damage to the pump unit, and even cause major operational failures. The water pump is driven by the shaft in operation, and the rotation speed of the shaft depends on the motor, water resistance and other friction forces, so the rotation speed of the shaft is an important water pump index. At the same t...

Problems solved by technology

[0003] The traditional water pump monitoring method adopts manual reading and manual data input and processing, which is time-consuming and laborious, and data input is also delayed, and the monitoring efficiency is low.

The on-site environment of the traditional water pump unit produces a lot of noise and vibration, and the data collected manually cannot fully reflect the actual working conditions, which will bring various errors, and the monitoring results have large errors

Traditional water pump sensor devices mostly use mechanical structures to measure various parameters. The measurement accuracy is greatly affected by the ambient temperature and humidity as well as the fatigue of the mechanism, and the accuracy of the measured parameters is low.

The traditional monitoring index processing devices are all integrated large chassis, and various index analysis modules are integrated together; when the monitoring points are scattered, and the number of monitored water pumps or the number of indicators changes, the functions of the integrated large chassis cannot be fully used, resulting in Monitor resource waste
