Pump sealing leakage monitoring and locating method

Abstract

A pump sealing leakage monitoring and locating method belongs to the application field of equipment health monitoring. A video monitoring camera is mounted in the side opposite to pump sealing side, avideo collector obtains a video signal of a leakage monitoring point, the video signal is converted into a digital signal, the digital signal is sent to a switch and further transformed to an integrated monitoring server for storage and backup, and online monitoring of pump sealing leakage is realized on the basis of online leakage monitoring software. The leakage point is located accurately themoment a leakage event occurs, a display terminal raises the alarm and displays location, and the event is avoided from being worse. The monitoring point which raises the alarm can be checked directlyand remotely, whether false alarm occurs is confirmed, and corresponding measures are taken; a position searching optimization technology of the specific video monitoring camera is used, so that moreleakage points can be monitored via fewer video monitoring cameras, the method is economical and efficient; and safety accidents, resource loss, economic loss, environment pollution and the like caused by pump sealing leakage can be avoided.

Description

technical field [0001] The invention belongs to the technical field of equipment health monitoring applications, and more specifically relates to a method for monitoring and locating seal leakage of a machine pump. Background technique [0002] Medium transportation and pipeline transportation are a major feature of the process industry. Common industrial fluids involve petroleum, natural gas, coal water slurry, sealing gas, instrument air, fire water, etc., and pumps, as power sources, play an indispensable and important role in them. Pump seal failure and leakage due to seal failure, medium corrosion, stress cracking, etc. occur from time to time. However, because most of the pump equipment is one for one use and one for standby, it is generally difficult to attract enough attention. However, for pumps that transport dangerous (highly corrosive, highly toxic, flammable, explosive, high temperature, high pressure, etc.) Economic loss and adverse social impact. If the le...
