Automatic control system for operation of oil well cement dry mixing station

Abstract

The invention relates to an automatic control system for operation of an oil well cement dry mixing station. The automatic control system for operation of the oil well cement dry mixing station comprises a programmable PLC (Programmable Logic Controller), and gas source, raw material feed and transmission, storage, dry mixing and dedusting control units. Associated signals of a device, an instrument, a pneumatic butterfly valve, a pneumatic proportional valve, a pressure sensor and a weighing sensor arranged on a pipeline of the individual control unit are collected and gathered. A control cabinet of each unit is controlled. The associated signals are transmitted to the programmable PLC control unit. Automatic control of operation of the oil well cement dry mixing station is realized by transmission signal processing, command feedback, Internet transmission, display and printing of each control unit through a PLC processor, the control cabinet, and a distribution cabinet, therefore, the workers are reduced, the labor intensity is lowered, the cement mixing efficiency and yield are improved, and the raw materials are saved. Dedusting discharge meets the national outdoor discharge standard, and the whole system is simple, convenient and safe to operate, and can be controlled remotely.

Description

technical field [0001] The invention relates to an automatic control system for the operation of an oil well cement dry mixing station, which changes the previous situation that the cement dry mixing depends entirely on manpower, and realizes the automatic control from raw materials entering the station to finished products leaving the station. Background technique [0002] Before the oil well cement dry mixing system appeared, the dry mixing operation of cement was basically realized manually. Not only the dry mixing efficiency was very low, but also a lot of manpower and material resources were consumed, which could not meet the requirements of dry mixing cement for well cementing operations. . Under such a background, through years of research and exploration, as well as the experience summed up in the construction of dry-mixing stations, researchers put forward the concept of automatic control of the operation of oil well cement dry-mixing stations, aiming to make oil-w...
