Intelligent slurry pump control system

Abstract

The invention discloses an intelligent slurry pump control system which includes a slurry pump body and a piston pressure detecting system, wherein the piston pressure detecting system includes a pressure sensor, a signal acquisition module, a signal processing module, an alarm module and a control module; the pressure sensor is arranged on the inner side of the cylinder sleeve of the slurry pump body and used for measuring pressure spectrum signals during the piston motion process in the cylinder sleeve; the signal acquisition module is used for acquiring the pressure spectrum signals; the signal processing module is used for analyzing the pressure spectrum signals to obtain corresponding data signals; the control module is used for controlling the alarm module to alarm and the slurry pump body to stop running temporarily according to the data signals output by the signal processing module. The intelligent slurry pump control system provided by the invention not only can monitor the running state of the slurry pump body in a real-time manner, but also can alarm in a real-time manner and stop equipment running according to the detected information, and analyze the faulty part for component replacement, so that the security and stability of the equipment operation are improved, and manpower and material resources as well as the cost are reduced.

Description

technical field [0001] The invention relates to the technical field of petroleum drilling engineering, in particular to an intelligent control system for mud pumps. Background technique [0002] As a kind of hydraulic equipment in oil field, mud pump is mainly used to provide high-pressure water to the downhole during oil well drilling operations, and at the same time carry out cuttings generated during drilling, and provide driving force for turbo drilling tools. It plays a very important role in mining work. [0003] The output pressure of the mud pump during the drilling process is as high as tens of MPa, and the output drilling fluid often contains sand and other types of abrasive particles. Under such high operating pressure and continuous action of various abrasive particles, the equipment’s Pistons and cylinder liners are prone to wear and leaks, leading to production accidents. Therefore, in order to avoid this leakage accident, the operator must always pay attenti...
