ZWY type coal mine mobile gas drainage pump
ZWY series mobile gas drainage pumping station for coal mines is a special safety equipment mainly used for underground gas drainage in coal mines to reduce local gas gushing and prevent coal and gas outbursts. At present, there are 13 models, and the pumping capacity ranges from 6 to 130.
It is mainly composed of air extraction system, monitoring and control system, air inlet and outlet pipelines, mobile pump chassis, shield and other parts. It has the characteristics of reasonable structure, small size, movable, easy installation, easy operation, safe and reliable operation, etc. It also has the functions of pumping and discharging parameters and environmental gas concentration monitoring, pumping station water supply monitoring, and can realize the environmental gas concentration exceeding the limit. Alarm power failure and abnormal power failure control of pumping station water supply, at the same time, it can also measure and calculate the drainage gas flow through the orifice flowmeter. It can be used as a local and temporary gas drainage equipment in the mine to make up for the lack of scope and capacity of the mine ground drainage system, and can also be used as the main equipment for gas drainage in local small and medium-sized mines.
Purpose and scope of application:
The purpose and scope of application of the mobile station are mainly reflected in the following aspects:
• Mine without the establishment of surface gas drainage system, such as local gas gushing or local coal and gas outburst areas. The characteristics of short-term gas drainage are required, such as mines where gas is ejected from the fissures of the volcanic rock.
•Although some mines have ground pumping stations, the underground working area is too remote to achieve effective drainage. Mobile pumping stations can be used for relay drainage.
• Local small and medium-sized coal mines can be pumped by mobile pumping stations, with small investment, quick results, and good safety and economic benefits.
•It is used for gas scientific research experiments. Before establishing a ground gas pumping station, use the mobile pumping station to conduct underground sampling tests, and determine the optimal drainage method and parameters by the test, so as to provide a reliable system for the establishment of permanent and ground pumping station drainage systems. According to the basis, to avoid blind investment causing waste.
