空壓機工作原理：
Working principle of air compressor:
當啟動裝置開啟后， 電動機進入正常運轉， 通過三角皮帶輪帶動壓縮機曲軸，再通過連桿和十字頭，使活塞在氣缸內作往復直線運動。當活塞由外止點向內止點開始移動時， 氣缸內側活塞外側處于低壓狀態(tài)，氣體通過近期閥進入汽缸， 當活塞由內止點向外止點移動時， 進氣閥關閉，氣缸內的氣體則被壓縮而提高壓力。當壓力超過排氣閥外氣體壓力時，排氣閥打開，開始排出壓縮氣體，當活塞到達外止點時排氣完畢。氣體經(jīng)過一級氣缸壓縮再經(jīng)中間冷卻器冷卻后，進入二級缸，同樣被壓縮后進入儲氣罐，以備使用。1、活塞式空壓機的原理 －－驅動機啟動后，經(jīng)三角膠帶，帶動壓縮機曲軸旋轉，通過曲柄桿機構轉化為活塞在氣缸內作往復運動。當活塞由蓋側向軸運動時，氣缸容積增大，缸內壓力低于大氣壓力，外界空氣經(jīng)濾清器，吸氣閥進入氣缸；到達下止點后，活塞由軸側向蓋側運動，吸氣閥關閉，氣缸容積逐漸變小，缸內空氣被壓縮，壓力升高，當壓力達到一定值時，排氣閥被頂開， 壓縮空氣經(jīng)管路進入儲氣罐內， 如此壓縮機周而復始地工作，不斷地向儲氣罐內輸送壓縮空氣，使罐內壓力逐漸增大，從而獲得所需的壓縮空氣。
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.
