空壓機(jī)工作原理:
Working principle of air compressor:
當(dāng)啟動(dòng)裝置開(kāi)啟后, 電動(dòng)機(jī)進(jìn)入正常運(yùn)轉(zhuǎn), 通過(guò)三角皮帶輪帶動(dòng)壓縮機(jī)曲軸,再通過(guò)連桿和十字頭,使活塞在氣缸內(nèi)作往復(fù)直線運(yùn)動(dòng)。當(dāng)活塞由外止點(diǎn)向內(nèi)止點(diǎn)開(kāi)始移動(dòng)時(shí), 氣缸內(nèi)側(cè)活塞外側(cè)處于低壓狀態(tài),氣體通過(guò)近期閥進(jìn)入汽缸, 當(dāng)活塞由內(nèi)止點(diǎn)向外止點(diǎn)移動(dòng)時(shí), 進(jìn)氣閥關(guān)閉,氣缸內(nèi)的氣體則被壓縮而提高壓力。當(dāng)壓力超過(guò)排氣閥外氣體壓力時(shí),排氣閥打開(kāi),開(kāi)始排出壓縮氣體,當(dāng)活塞到達(dá)外止點(diǎn)時(shí)排氣完畢。氣體經(jīng)過(guò)一級(jí)氣缸壓縮再經(jīng)中間冷卻器冷卻后,進(jìn)入二級(jí)缸,同樣被壓縮后進(jìn)入儲(chǔ)氣罐,以備使用。1、活塞式空壓機(jī)的原理 --驅(qū)動(dòng)機(jī)啟動(dòng)后,經(jīng)三角膠帶,帶動(dòng)壓縮機(jī)曲軸旋轉(zhuǎn),通過(guò)曲柄桿機(jī)構(gòu)轉(zhuǎn)化為活塞在氣缸內(nèi)作往復(fù)運(yùn)動(dòng)。當(dāng)活塞由蓋側(cè)向軸運(yùn)動(dòng)時(shí),氣缸容積增大,缸內(nèi)壓力低于大氣壓力,外界空氣經(jīng)濾清器,吸氣閥進(jìn)入氣缸;到達(dá)下止點(diǎn)后,活塞由軸側(cè)向蓋側(cè)運(yùn)動(dòng),吸氣閥關(guān)閉,氣缸容積逐漸變小,缸內(nèi)空氣被壓縮,壓力升高,當(dāng)壓力達(dá)到一定值時(shí),排氣閥被頂開(kāi), 壓縮空氣經(jīng)管路進(jìn)入儲(chǔ)氣罐內(nèi), 如此壓縮機(jī)周而復(fù)始地工作,不斷地向儲(chǔ)氣罐內(nèi)輸送壓縮空氣,使罐內(nèi)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.
