一、性能介绍我厂动力总站四压风站的一台空压机是无锡压缩机厂生产的5L-40/8型空气压缩机。使用压力为4～8kgf/cm~2,排气量为40m~3/min,其工作原理见图1。当电动机启动后,带动曲轴1并通过连杆2和十字头3将曲轴的圆周运动变为活塞5的直线往复运动。两级气缸6、7的内外两侧各有一对吸、排气阀8、9。当活塞由外死点A向内死点B运动时,气缸内活塞外侧的压缩气体的体积不断膨胀,当压力低于大气压时,
First, the performance of the introduction of our plant four air compressor station air compressor is a compressor factory in Wuxi 5L-40/8 air compressor. Working pressure is 4 ~ 8kgf / cm ~ 2, displacement is 40m ~ 3 / min, the working principle shown in Figure 1. When the motor is started, the crankshaft 1 is driven and the circular motion of the crankshaft is changed to the linear reciprocating motion of the piston 5 through the connecting rod 2 and the crosshead 3. Two cylinders 6, 7 on both sides of each have a pair of suction, exhaust valve 8,9. When the piston moves from the dead point A to the dead point B inward, the volume of the compressed gas outside the piston in the cylinder continues to expand. When the pressure is lower than the atmospheric pressure,
