The coal mine underground mobile gas pumping station can be used for local, temporary gas drainage and drainage and anti-burst of mines to compensate for the lack of drainage and capacity of mine ground drainage system, and can also be used as local small and medium-sized mine gas drainage. The main equipment put.
The coal mine underground gas pumping station is driven by an explosion-proof motor to drive the water ring vacuum pump impeller to generate suction and exhaust effects, which achieves the purpose of pumping. The gas flow concentration of the pumping pipeline is monitored by the orifice flowmeter and the high-moisture sensor, and the turbidity of the gas is calculated by calculation; the low-moisture sensor monitors the gas concentration of the operating environment of the pumping station, and the water supply sensor monitors and controls the water supply of the pumping station. When the water supply quantity is less than the specified water supply quantity or the gas concentration of the pumping station operating environment exceeds the safety value specified by the relevant regulations, the automatic power-off of the pumping station is realized by the gas power failure control.
The ZWY coal mine underground mobile gas pumping station (hereinafter referred to as the pumping station) is a special safety equipment used for underground coal mine gas drainage to reduce local gas emission and prevent coal and gas outburst. It is mainly composed of water ring vacuum pump, explosion-proof three-phase asynchronous motor (hereinafter referred to as explosion-proof motor), steam-water separator, monitoring and monitoring system and base frame. The monitoring and monitoring system mainly includes: KG9701A low-concentration methane sensor (hereinafter referred to as low-moisture sensor), GUY mine intrinsically safe water supply sensor (hereinafter referred to as water supply sensor), GJT100S high-low concentration methane sensor for gas pipeline (hereinafter referred to as high-altitude sensor) ), KFD-4 type mine explosion-proof and intrinsically safe controller (hereinafter referred to as gas de-energizer), orifice flowmeter, etc.
