System for measuring and analysis of vibration in electric motors of irrigation facilities

This article analyzes the vibration process that occurs in electric motors in irrigation facilities. It has been studied that various failures and electric motor imbalances and vibrations that can occur during the operation of electric motors at pumping stations have a negative impact on the whole system. Electrical and mechanical failures affect the normal operation of the electric motor, i.e. increase power consumption, increase current, increase heat, and also increase vibration. Balancing is an important requirement for electric motors and all rotating components. A modern SD-21 vibrodiagnostic device was used to detect vibration. The research was carried out using the method of comparing the trajectory obtained in the mode of synchronous accumulation using the vibrodiagnostic device SD-21. In the course of the research, the main factors that cause vibration in electric motors, the method of identification of decentralization that causes high vibration, the spectral and informative properties of vibrating signals were studied. The advantages of predicting the deviation of vibrations in electric motors from the allowable are highlighted. A virtual tool has been developed to detect and analyze vibration.
