负压自动风门系利用扇风机运转在风峒内产生的负压(即风压)而自行开启和关闭的一种风门。过去我矿扇风机风峒风门都是悬吊式或闸板式,这两种旧式风门都存在着构造笨重、操作复杂的缺点,非常不便。特别是在东北地区,冬季气候寒冷,往往因结冰而将风门或其传动部分冻住,以致造成操作系统失灵,这是过去长期没有解决的问题。在无产阶级文化大革命中,在毛主席革命路线指引下,我矿广大职工发扬“自力更生,艰苦奋斗,破除迷信,解放思想”的革命精神,对风峒风门进行了大胆革新。经过反复试验,终于创制了这种负压自动风门,并于一九六八年试运成功,从而彻底解决了旧式风门存在的问题。从同
The negative pressure automatic damper is a type of damper that opens and closes by using the fan (fan) to operate the negative pressure (ie, the air pressure) generated in the fan. In the past I mine fan wind 峒 throttle are hanging or ram-type, both of these old throttle there is the structure bulky, complex operation of the shortcomings, very inconvenient. Particularly in the northeast, cold weather in winter tends to freeze the damper or its transmission part due to icing, resulting in malfunction of the operating system, which has not been solved for a long time in the past. In the Great Proletarian Cultural Revolution, under the guidance of Chairman Mao’s revolutionary line, the vast majority of mine workers carried forward the revolutionary spirit of “self-reliance, hard work, breaking superstition and emancipating the mind,” and boldly renovated the tyrant’s tyrant. After repeated tests, this negative pressure automatic damper was finally created and successfully commissioned in 1968, thus thoroughly solving the problems existing in the old damper. From the same
