空压机工作原理：
Working principle of air compressor:
当启动装置开启后， 电动机进入正常运转， 通过三角皮带轮带动压缩机曲轴，再通过连杆和十字头，使活塞在气缸内作往复直线运动。当活塞由外止点向内止点开始移动时， 气缸内侧活塞外侧处于低压状态，气体通过近期阀进入汽缸， 当活塞由内止点向外止点移动时， 进气阀关闭，气缸内的气体则被压缩而提高压力。当压力超过排气阀外气体压力时，排气阀打开，开始排出压缩气体，当活塞到达外止点时排气完毕。气体经过一级气缸压缩再经中间冷却器冷却后，进入二级缸，同样被压缩后进入储气罐，以备使用。1、活塞式空压机的原理 －－驱动机启动后，经三角胶带，带动压缩机曲轴旋转，通过曲柄杆机构转化为活塞在气缸内作往复运动。当活塞由盖侧向轴运动时，气缸容积增大，缸内压力低于大气压力，外界空气经滤清器，吸气阀进入气缸；到达下止点后，活塞由轴侧向盖侧运动，吸气阀关闭，气缸容积逐渐变小，缸内空气被压缩，压力升高，当压力达到一定值时，排气阀被顶开， 压缩空气经管路进入储气罐内， 如此压缩机周而复始地工作，不断地向储气罐内输送压缩空气，使罐内压力逐渐增大，从而获得所需的压缩空气。
When the starting device is turned on, the motor enters normal operation, drives the compressor crankshaft through the triangular belt pulley, and then makes the piston move back and forth in a straight line in the cylinder through the connecting rod and crosshead. When the piston starts to move from the outer dead center to the inner dead center, the outside of the piston inside the cylinder is in a low-pressure state, and the gas enters the cylinder through the near-term valve. When the piston moves from the inner dead center to the outer dead center, the inlet valve is closed, and the gas in the cylinder is compressed to increase the pressure. When the pressure exceeds the gas pressure outside the exhaust valve, the exhaust valve opens and begins to discharge the compressed gas. When the piston reaches the outer dead center, the exhaust is completed. After being compressed by the primary cylinder and cooled by the intercooler, the gas enters the secondary cylinder. After being compressed, it enters the air storage tank for use. 1. The principle of piston air compressor - after the driver is started, it drives the compressor crankshaft to rotate through the triangular belt, which is transformed into a piston through the crank rod mechanism to make reciprocating motion in the cylinder. When the piston moves from the cover to the shaft, the cylinder volume increases, the pressure in the cylinder is lower than the atmospheric pressure, and the external air enters the cylinder through the filter and suction valve; After reaching the bottom dead center, the piston moves from the shaft side to the cover side, the suction valve is closed, the cylinder volume gradually decreases, the air in the cylinder is compressed and the pressure increases. When the pressure reaches a certain value, the exhaust valve is pushed open, and the compressed air enters the air storage tank through the pipeline. In this way, the compressor works round and round, continuously transmits compressed air to the air storage tank, and gradually increases the pressure in the tank, So as to obtain the required compressed air.
