空壓機工作原理 Working principle of air compressor 1. 螺桿式空壓機 Screw air compressor 介紹雙螺桿式單級壓縮空壓機是由一對相互平行齒合的陰陽轉(zhuǎn)子（或稱螺桿）在氣缸內(nèi)轉(zhuǎn)動，使轉(zhuǎn)子齒槽之間的空氣不斷地產(chǎn)生周期性的容積變化，空氣則沿著轉(zhuǎn)子軸線由吸入側(cè)輸送至輸出側(cè)，實現(xiàn)螺桿式空壓機的吸氣、壓縮和排氣的全過程。空壓機的進(jìn)氣口和出氣口分別位于殼體的兩端，陰轉(zhuǎn)子的槽與陽轉(zhuǎn)子的齒被主電機驅(qū)動而旋轉(zhuǎn)。 由電動機直接驅(qū)動壓縮機，使曲軸產(chǎn)生旋轉(zhuǎn)運動，帶動連桿使活塞產(chǎn)生往復(fù)運動，引起氣缸容積變化。由於氣缸內(nèi)壓力的變化，通過進(jìn)氣閥使空氣經(jīng)過空氣濾清器（消聲器）進(jìn)入氣缸，在壓縮行程中，由於氣缸容積的縮小，壓縮空氣經(jīng)過排氣閥的作用，經(jīng)排氣管，單向閥（止回閥）進(jìn)入儲氣罐，當(dāng)排氣壓力達(dá)到額定壓力0.7MPa時由壓力開關(guān)控制而自動停機。當(dāng)儲氣罐壓力降至0.5--0.6MPa時壓力開關(guān)自動聯(lián)接啟動。 Introduce double screw type single stage compression air compressor is composed of a pair of parallel tooth rotor (or screw), Yin and Yang of rotation, inside the cylinder between the rotor alveolar air constantly produce periodic changes in volume, the air is along the rotor axis by suction side to the output side, screw air compressor suction, compression and exhaust process. The inlet and outlet of the air compressor are located at opposite ends of the shell, and the slot of the Yin rotor and the tooth of the male rotor are driven by the main motor. The motor drives the compressor directly, causing the crankshaft to rotate, and the connecting rod causes the piston to reciprocate, causing the cylinder volume to change. Due to the change of pressure in the cylinder, through the inlet valve to make the air through the air filter (silencer) into the cylinder, in the compression stroke, due to the cylinder volume reduction, the role of compressed air through the exhaust valve, the exhaust pipe, one-way valve (check valve) to storage tanks, when the exhaust pressure to achieve the rated pressure of 0.7 MPa is controlled by a pressure switch and automatic stop. The pressure switch automatically connects when the reservoir pressure drops to 0.5-0.6 MPa. 2. 旋葉式壓縮機 Rotary vane compressor 每種型號的壓縮機對潤滑油的要求都是不同的。旋葉式壓縮機的潤滑油功能是潤滑在壓縮過程中滑入和滑出的葉家莊電動伸縮門 保定桌椅 保定水處理設(shè)備 河北機械加工 保定養(yǎng)老院 保定防水片。潤滑油也作為葉片與機架間的密封劑使用，使氣體壓縮成為可能。通常ISO68-150產(chǎn)品滿足旋葉式壓縮機的粘度要求。 Each type of compressor has a different requirement for lubricating oil. The lubricant function of the rotary vane compressor is the sliding and sliding of the blade in the compression process. Oil is also used as a sealant between blade and rack, which makes the gas compression possible. Normally iso680-150 products meet the viscosity requirements of rotary vane compressor. 3. 往復(fù)式壓縮機 Reciprocating compressor 空壓機往復(fù)式壓縮機提供了一個很大的流出壓力容量范圍從1bar g至1000bar g。往復(fù)式壓縮機的油潤滑汽缸，曲軸箱部件，線圈，活塞，閥門和裝填桿。曲軸箱部件包括十字頭軸承，十字接頭，十字頭導(dǎo)承和曲柄銷。近來的制冷應(yīng)用表明操作粘度小于10 cSt的ISO15潤滑油可提供合適的潤滑作用。然而，依靠氣體分子量和流壓操作，加工和碳?xì)浠衔餁怏w往復(fù)式壓縮機的經(jīng)典使用是ISO68-680產(chǎn)品。 The compressor provides a large outflow pressure range from 1bar g to 1000bar g. The oil lubrication cylinder, crankcase parts, coils, pistons, valves and loading poles of reciprocating compressor. The crankcase parts include crosshead bearings, cross joints, crosshead guide and crank pin. Recent refrigeration applications show that ISO15 lubricating oil with viscosity less than 10 cSt provides suitable lubrication. However, the classic usage of gas reciprocating compressor for processing and hydrocarbon gas is iso68-680 based on gas molecular weight and flow pressure operation.
