1973～1986年间,美国矿山安全卫生管理局受理了涉及油浸螺杆式压气机(OFRSC)的12起火灾事故,其中大多数是由于保护装置故障或不适时的维修保养引起的。螺杆式压气机的压气是由两个互相啮合的转子(即螺杆)在定子内旋转而产生的。注入压气机内的油起冷却、密封和润滑作用。当压气由大气压力被压缩到较高的排出压力时,要产生一定的热量。 Between 1973 and 1986, the U.S. Sanitary and Sanitary Board accepted 12 fire accidents involving OFRSC, the majority of which were caused by maintenance or repair of faulty protective devices. Compression of screw compressors results from the rotation of two intermeshing rotors (ie, screws) within the stator. The oil injected into the compressor acts as a cooling, sealing and lubricating element. When the pressure from the atmospheric pressure is compressed to a higher discharge pressure, to produce a certain amount of heat.
