This product is a special equipment for gas extraction or discharge from mined-out area of coal seam, rock formations and goaf.
Gas pumping station on the ground, connecting with the drainage hole through the underground gas drainage pipeline system , negative pressure caused when pump runs, the gas after extracted, send into gas cans, or direct supplied to users. If outlet a smaller quantity of gas, or unstable, can be directly discharged to the atmosphere.
Gas Pump Station currently has characteristics of variety of models, and complete functions, reasonable institutional , safe, reliable, good performance, easy to move and other, the main function in addition to water ring vacuum pump, exhaust and stable performance, but also with self-control protection functions: one is water power auto cut function; the other one is power automatically cut during environmental testing functions.
1. coal mine well which has no ability to establish ground mine gas drainage system, such as a partial or localized gas emission coal and gas outburst area; locations need short-term for gas drainage , wells have caves or mine gas ejected crevices.
2. although there are some ground mine gas drainage pumping station, but the underground work in remote areas, can not achieve effective drainage,which can be used to mine gas drainage pumping stations for mobile Relay drainage.
3. the ground pumping station malfunctioning for some reason, we can use the mobile pumping station on the main areas underground gas drainage.
4. the local small coal mines can be moved drainage pumping stations, small investment, quick, with better security and economic benefits.
5. for scientific research and experiments of gas, gas drainage pumping station in the establishment of the ground before using a mobile downhole pumping test pumping, drainage from the test to determine the best methods and drainage parameters for the establishment of ground pumping stations provide a reliable basis, avoid blind investment wastage.
6. for the pre-pumping, while excavation and pumping, pumping while mining, upper corner drainage, drainage ability flows.
7. no gas concentration restrictions if drainage using water ring vacuum pump.
8. if use extracted gas,its concentration must be considered, not less than 30% of the requirement.
