Intelligent control device for direct-drive screw pump

Abstract

The invention discloses an intelligent control device for a direct-drive screw pump, and relates to the technical field of equipment for oil and gas exploitation. The device comprises a control box, a heat dissipation mechanism is connected to the center of the upper end face of the control box in a penetrating mode, an isolation mechanism is connected to the center of the rear end face of the control box in a penetrating mode, and a control module is slidably connected to the middle in the control box; the fault positioning mechanisms are arranged on the upper rear portion of the control box at equal intervals, wireless transceivers are connected to the middles of the front ends of positioners included in the fault positioning mechanisms in an embedded mode, auxiliary searching mechanisms at the upper ends of the positioners penetrate through the middles of the functional mounting mechanisms above the auxiliary searching mechanisms, and alarms are arranged above the functional mounting mechanisms. According to the control device, by arranging the fault positioning mechanism, the function mounting mechanism and the auxiliary searching mechanism, the problems that an existing control device is difficult to accurately position, search and overhaul the direct-drive screw pump, or the mounting environment of a positioning structure is exposed and is easy to damage, and meanwhile, the position of a mounting mechanism is difficult to determine are solved.

Description

technical field [0001] The invention belongs to the technical field of equipment for oil and gas development, and in particular relates to an intelligent control device for a direct-drive screw pump. Background technique [0002] Oil and gas extraction is the process of extracting oil and natural gas buried in underground oil layers from the ground. The way oil and gas are extracted from the ground to the ground can be divided into two types according to whether artificial energy needs to be added to the wellbore fluid: self-injection and artificial lift. Control jobs. [0003] After retrieval, China Authorized Publication No. CN102953984B, authorized publication date 2015.12.09, authorized to disclose a direct-drive screw pump soft stop control method and equipment, the method includes the shutdown detection unit detecting the external input of the direct-drive screw pump shutdown command Then start the multi-stage speed adjustment unit; the multi-stage speed adjustment u...

AI Technical Summary

Problems solved by technology

[0009] The purpose of the present invention is to provide an intelligent control device for a direct-drive screw pump. By setting a fault-fixing mechanism, an auxiliary search mechanism and a function installation mechanism, the existing control device is solved. After the drive screw pump fails to work normally, it is difficult to accurately locate and repair the direct drive screw pump, or when the faulty direct drive screw pump is accurately located and searched, its positioning structure is exposed to the installation environment, easily damaged and easily lost. At the same time, after the above-mentioned concealed installation is carried out, it is difficult for the operator to determine its position, which causes the problem of inconvenience in use.
