瓦斯抽放设备选型

The Gas Drainage Equipment Selection

由于瓦斯抽放效果主要取决于抽放设备,因此根据设计依据,详细计算瓦斯泵流量、管径、管道阻力、抽放泵压力、抽放泵系统压力及其密度,根据计算结果的选型原则,确定瓦斯抽放泵的型号。实践表明:合理的瓦斯抽放系统能有效缓解综采工作面瓦斯超限的问题。

Because the gas drainage effect mainly depends on the drainage equipment, according to the design basis,with the resistance calculation of gas pump flow, pipe diameter, pipe pressure, drainage pump, drainage pump system pressure and density, according to the principle of selecting the calculation results, determine the gas drainage pump model. Practice shows that the system can effectively relieve fully mechanized coal face gas pumping reasonable gas problem.
