大氣端的密封為帶有輔助密封圈的滑動(dòng)式機(jī)械密封，串聯(lián)布置。圖9一8(a)中，密封腔配有進(jìn)出管線，可向機(jī)械密封的介質(zhì)端和大氣端區(qū)間的密封腔內(nèi)注人流體，防止介質(zhì)端微量泄漏熱分解積炭。該密封有由裝在泵上方的儲(chǔ)罐向密封腔內(nèi)供油，靠大氣端的機(jī)械密封轉(zhuǎn)動(dòng)座的泵送螺旋來(lái)實(shí)現(xiàn)流體的循環(huán)，確保了機(jī)械密封的冷卻和潤(rùn)滑。圖9-8(b)的密封結(jié)構(gòu)和圖(a)的相同，不同的地方是圖(b)由泵的出口法蘭處引人部分流體至旋液分離器，經(jīng)旋液分離器分離后，含有固體顆粒的流體返回泵的進(jìn)口，而凈化的流體供給介質(zhì)端機(jī)械密封作為沖洗液使用。旋液分離器后的循環(huán)管線有一段是螺旋形的盤(pán)管，因而使該密封腔內(nèi)的流體溫度比泵送介質(zhì)溫度約低50℃。由于液流引自泵出口處，使密封腔內(nèi)壓力升高并始終作用在機(jī)械密封扛。如此，可避免端面產(chǎn)生磨粒磨損和端面間的液膜汽化。泵送高溫渣油、“落地原油”等可推薦使用圖(b)所示的沖洗循環(huán)系統(tǒng)。寶雞襄樊五二五機(jī)械密封IH-25S320襄樊五二五機(jī)械密封LC600/825。</p><div
