Stable operation control system for gas extraction pump based on expert system

Abstract

The invention provides a stable operation control system for a gas extraction pump based on an expert system. The stable operation control system comprises a programmable control cabinet, an upper computer, a gas water circulation pump, a pump motor and a water-gas separator, the output end of the pump motor is connected with the power input end of the gas water circulation pump through a pump speed reducer, a water-gas outlet of the gas water circulation pump is connected with a water-gas inlet of the water-gas separator, a water outlet of the water-gas separator is connected with a water inlet of a cooling water pond, a water outlet of the cooling water pond is connected with a water inlet of a high-level water pond, a water outlet of the high-level water pond is connected with a water inlet of the gas water circulation pump, a connecting pipeline of the gas water circulation pump and the high-level water pond is provided with a PLC constant-pressure control cabinet and a position-type electric adjusting valve, and a pipeline flowmeter is arranged on an underground gas drainage pipeline. According to the stable operation control system, various work states and operation parameters of the gas drainage pump can be monitored really, operation can be remotely controlled, and the purposes that the unattended underground dangerous environment is achieved, energy sources are saved,the labor intensity is lowered, the operation cost is lowered, and the service life of equipment is prolonged are achieved.

Description

technical field [0001] The invention belongs to the technical field of gas drainage, and in particular relates to an adaptive adjustment control system for stable operation of a gas drainage pump. Background technique [0002] The main function of the gas drainage pump station is to collect the capillary drainage pipelines arranged in the underground coal seam and empty coal seam, and then lead to the ground drainage pump station through the main pipeline. The gas is pumped through the pipeline to the ground for discharge or sent to the gas power plant for gas utilization. When the gas drainage pump station is working, first open the exhaust valve, start the pump motor, the pump motor runs to drive the reducer to rotate, thereby driving the water circulation pump to work, then open the intake valve; open the water intake valve of the water circulation pump, the water circulation pump rotates , the water entering the cavity is rotated and dispersed until the casing and the r...

Problems solved by technology

[0003] Therefore, it is necessary to make the inlet water flow rate and the vacuum degree of the vacuum pump reach a balance value, and the main specific parameters that characterize the vacuum degree of the vacuum pump: - negative pressure, auxiliary parameters - load current, currently using manual adjustment to adjust the opening of the valve, the operation Manual on-site control is adopted, and the water inflow is adjusted based on comprehensive consideration of observed negative pressure, flow, temperature, gas concentration and other parameters. It is impossible to grasp the operating status of the equipment in real time, and it is impossible to monitor and control the field data in real time. The modern management level of the mine is low.
