Injection pump unit fault diagnosis method and device

Abstract

The invention relates to an injection pump unit fault diagnosis method and device. The injection pump unit fault fixed type on-line diagnosis method is a method combining fixed type diagnosis and portable diagnosis for diagnosing an injection pump unit fault, a fixed type diagnosis method is characterized in that a 16-channel vibration synchronous data collector and a power source are used for manufacturing an on-line vibration monitor to be fixedly installed on site, vibration signals of a vibration acceleration sensor fixedly installed on an injection pump unit are collected, the signals areremotely transmitted to a water injection management system terminal computer through an Ethernet data communication RJ45 connector in a wireless manner or transmitted to an on-site transferring computer in a wired manner through an RS232 on-site management interface, or alarming instructions are made according to the LED state of an on-site vibration monitor, meanwhile, a portable diagnosis method is used for conducting injection pump unit fault diagnosis and compassion, an accurate injection pump unit fault point and a reason causing fault vibration are judged, in-time treatment is achieved, and malignant accidents are eliminated in sprouts.

Description

technical field [0001] The invention relates to the technical field of oilfield water injection management, in particular to a fault diagnosis method and device for a water injection pump unit. Background technique [0002] At present, in the process of water flooding in oilfields, the oil in the oil layer is mainly displaced by the water injection of the water injection pump, so as to improve the oil recovery rate of the oilfield. Common water injection pump units mainly include high-pressure centrifugal water injection pumps and high-pressure plunger pump units. The water injection pump is very prone to evacuation and motor burnout during use, which seriously affects the completion of the water injection plan and oil production tasks. Strengthening the status monitoring and fault diagnosis of the water injection pump is an urgent need in the current management of the water injection pump. Contents of the invention [0003] The purpose of the present invention is to pro...
