Monitoring device for service performance of water pump

Abstract

The invention discloses a monitoring device for service performance of a water pump. The monitoring device is technically characterized by comprising the water pump, a vibration sensor, a vibration signal processor, a pressure sensor, a pressure signal processor, a temperature sensor, a temperature signal processor, a noise sensor, a noise signal processor, an optical-electric encoder, an optical-electric signal processor, a processor, a display screen and an alarm device. The vibration sensor, the pressure sensor, the temperature sensor, the noise sensor and the optical-electric encoder are adopted for monitoring the vibration, pressure, temperature, noise and rotating speed of the water pump in real time. The optical-electric encoder is adopted as the core of a rotating speed detection device, and the rotating speed of the water pump can be monitored in real time rapidly and accurately. The display screen and the processor are connected, and therefore the service performance of the water pump can be monitored in real time. The alarm device and the processor are connected, and an alarm can be given when water pump data are abnormal.

Description

technical field [0001] This patent relates to a detection device in the field of water conservancy and hydropower, in particular to a performance monitoring device for water pumps. Background technique [0002] Pumping stations play an important role in industry, agriculture, production and life, so the reliable operation of pumping stations is very important. Among them, the water pump is a vital part of the pumping station. The water pump is a low-speed rotating machine. The faults of the water pump can be divided into congenital faults and acquired faults according to the time of occurrence. The congenital faults are caused by the process of manufacturing and installing the pump. It is caused by problems such as precision coordination during the installation process, and for the pump unit, acquired failure is the key to prevention. [0003] The traditional maintenance measures are regular maintenance and after-the-fact maintenance. This maintenance method has great disa...

AI Technical Summary

Problems solved by technology

[0003] The traditional maintenance measures are regular maintenance and after-the-fact maintenance. This maintenance method has great disadvantages. In many cases, mechanical equipment has obviously failed but the maintenance period has not yet expired. It needs to go through multiple layers of applications before it can be repaired. Regular maintenance will be difficult. The machine has been severely worn and has reached the level of being scrapped. Sometimes it is found that the unit is in good condition during the maintenance process and does not need to be repaired at all. Under such a maintenance policy, under-maintenance and over-maintenance are often encountered, which will not only cause damage to the unit, but also increase the downtime of the unit, reduce the production efficiency of the unit, and increase the cost of unit operation
