黄沙坪铅锌矿开放式调压风机站及其参数选择

降低小风阻网孔的漏风, 可在不增阻的情况下有效增加高阻网孔进风端的进风量,而不影响进风分路的行人通车问题。开放式机站是采用低压大风量风幕原理设计的一种新式风机站, 适应于多风机串并联通风系统进风端的调压控制。介绍了开放式机站的设计原理, 计算机优化选择机站参数和风机的方法。

HUANGSHAPIN LEAD-ZINCMINE′S OPEN-TYPE PRESSURE-REGULATING FAN STATION AND ITS PARAMETER SELECTION

Reduction in air leakage of low-resistance meshes can achieve effective increase in air inflow of air-inlet of high-resistance meshes without increasing its resistance, instead of affect t ravel and traffic on the air inlet branch.The station is designed according to the principles of a low-pressure and large air capacity air curtain, and is suitabe for controlling the air-inlet end of a series-parallel ventilation system of several fans by pressure-regulation.The author describes the designing principles of the open-type fan station and the computer-optimized selection of its parameters and fans.
