MOXA AWK-3121-JP-T IEEE802.11A/B/G WIRELESS AP/BRIDGE/CLIEN 1231 328螺桿壓縮機(jī)內(nèi)置變速齒輪通過(guò)很小的接觸面?zhèn)鬟f較大功率，潤(rùn)滑油的負(fù)荷是很大的，對(duì)潤(rùn)滑油的要求和對(duì)潤(rùn)滑系統(tǒng)的要求遠(yuǎn)遠(yuǎn)高于螺桿壓縮機(jī)機(jī)頭。螺桿壓縮機(jī)對(duì)雜質(zhì)含量的容忍程度，對(duì)于齒輪而言是不能允許的。螺桿壓縮機(jī)啟動(dòng)過(guò)程中的油壓缺失對(duì)于齒輪來(lái)說(shuō)是致命的。
從潤(rùn)滑角度看，螺桿壓縮機(jī)內(nèi)置變速齒輪是一個(gè)嚴(yán)重的設(shè)計(jì)缺陷。，盡管油分罐內(nèi)部空氣溫度保持在壓力露點(diǎn)以上，但油分密封作用：螺桿機(jī)油在螺桿空壓機(jī)內(nèi)部有多條泄漏通道，這些泄漏通道都是一些狹長(zhǎng)的間隙，油的存在極大地強(qiáng)化了密封效果，使得通過(guò)它們的泄漏量大為減少。冷卻作用：噴入的油呈微滴狀，與被壓縮的氣體混合，極大的換熱表面迅速吸收氣體的壓縮熱，冷卻了壓縮介質(zhì)，大大降低了排氣溫度潤(rùn)滑作用：在干式螺桿空壓機(jī)中，兩轉(zhuǎn)子相互不接觸，依靠高精度的同步齒輪保持間隙。
螺桿機(jī)油而在噴油空壓機(jī)中，由于有大量的油存在，并且陰轉(zhuǎn)子只吸收壓縮總耗功的一小部分，從而可以把同步齒輪省掉，使陽(yáng)轉(zhuǎn)子直接驅(qū)動(dòng)陰轉(zhuǎn)子。另外，由于噴入的油同軸承所用的潤(rùn)滑油完全一樣，所以不再需要用一套復(fù)雜的密封裝置把氣體同潤(rùn)滑油隔開，這使得轉(zhuǎn)子支撐軸承之間的距離可以更小，顯著提高了轉(zhuǎn)子的剛度，減小了變形。螺桿機(jī)油罐壁面溫度在內(nèi)外溫差的作用下通常都在壓力露點(diǎn)以下，即油分罐內(nèi)壁掛水是無(wú)法避免的。
