原因水質(zhì)差含顆粒。由于水質(zhì)差，含有小顆粒及介質(zhì)中鹽酸鹽含量高，形成磨料磨損機封的平面或拉傷表面產(chǎn)生溝槽、環(huán)溝等現(xiàn)象。處理辦法：改進水壓或介質(zhì)，更換機封。原因缺水運行造成干磨損壞。此現(xiàn)象多見于底閥式安裝形式進口處負壓，進水管有空氣，泵腔內(nèi)有空氣，泵開機后，機封的磨擦高速運轉(zhuǎn)時產(chǎn)生高溫，無法得到冷卻，檢查機封，彈簧張力正常，摩擦面燒焦發(fā)黑，橡膠變硬開裂。處理辦法：排盡管道及泵腔內(nèi)空氣，更換機械密封。

一般來說，羅茨蒸汽壓縮風機的轉(zhuǎn)速在98～145r/min，普通離心蒸汽壓縮風機的轉(zhuǎn)速在6～9r/min，而單級高壓離心風機的高轉(zhuǎn)速可達3r/min。當然，對于羅茨風機來說，其劣勢也很明顯，其單級體積流量過小、效率低、保養(yǎng)周期短(一般2h/次)是其先天缺陷;同時羅茨風機噪聲頻譜較寬，且以63-8HZ的低中頻噪音為主要成份，在運行中的噪聲高達1分貝以上，對人員健康傷害較大。

一般系統(tǒng)設(shè)計為壓縮機停機一定時間后四通閥才換向，此時高低壓趨于平衡，換向到中間位置便停止，即四通閥換向不到位，主滑閥停在中間位置，下次啟動時，由于中間流量作用造成流量不足；壓縮機啟動時流量不足。四通閥換向不良原因四通閥線圈斷路、短路或電壓不符合線圈性能要求，造成先導閥的閥芯不能動作；由于外部原因，先導閥部變形，造成閥芯不能動作；先導閥毛細管變形或堵塞，造流量不足，形成不了換向所需的壓力差；主閥體變形，活塞部被卡死而不能動作；冷凍油變質(zhì)或系統(tǒng)內(nèi)進入雜物，四通閥活塞卡死；四通閥焊接時，溫度過高，內(nèi)部零件發(fā)生熱變形而不能動作；制冷系統(tǒng)冷媒泄漏，冷媒循環(huán)量不足，達不到換向所需的壓力；壓縮機溫度過高，由于制冷劑泄漏等原因壓縮機得不到很好的冷卻，排氣溫度過高導致四通閥內(nèi)部零件變形卡死或換向不靈。

原因水質(zhì)差含顆粒。由于水質(zhì)差，含有小顆粒及介質(zhì)中鹽酸鹽含量高，形成磨料磨損機封的平面或拉傷表面產(chǎn)生溝槽、環(huán)溝等現(xiàn)象。處理辦法：改進水壓或介質(zhì)，更換機封。原因缺水運行造成干磨損壞。此現(xiàn)象多見于底閥式安裝形式進口處負壓，進水管有空氣，泵腔內(nèi)有空氣，泵開機后，機封的磨擦高速運轉(zhuǎn)時產(chǎn)生高溫，無法得到冷卻，檢查機封，彈簧張力正常，摩擦面燒焦發(fā)黑，橡膠變硬開裂。處理辦法：排盡管道及泵腔內(nèi)空氣，更換機械密封。

一般來說，羅茨蒸汽壓縮風機的轉(zhuǎn)速在98～145r/min，普通離心蒸汽壓縮風機的轉(zhuǎn)速在6～9r/min，而單級高壓離心風機的高轉(zhuǎn)速可達3r/min。當然，對于羅茨風機來說，其劣勢也很明顯，其單級體積流量過小、效率低、保養(yǎng)周期短(一般2h/次)是其先天缺陷;同時羅茨風機噪聲頻譜較寬，且以63-8HZ的低中頻噪音為主要成份，在運行中的噪聲高達1分貝以上，對人員健康傷害較大。

一般系統(tǒng)設(shè)計為壓縮機停機一定時間后四通閥才換向，此時高低壓趨于平衡，換向到中間位置便停止，即四通閥換向不到位，主滑閥停在中間位置，下次啟動時，由于中間流量作用造成流量不足；壓縮機啟動時流量不足。四通閥換向不良原因四通閥線圈斷路、短路或電壓不符合線圈性能要求，造成先導閥的閥芯不能動作；由于外部原因，先導閥部變形，造成閥芯不能動作；先導閥毛細管變形或堵塞，造流量不足，形成不了換向所需的壓力差；主閥體變形，活塞部被卡死而不能動作；冷凍油變質(zhì)或系統(tǒng)內(nèi)進入雜物，四通閥活塞卡死；四通閥焊接時，溫度過高，內(nèi)部零件發(fā)生熱變形而不能動作；制冷系統(tǒng)冷媒泄漏，冷媒循環(huán)量不足，達不到換向所需的壓力；壓縮機溫度過高，由于制冷劑泄漏等原因壓縮機得不到很好的冷卻，排氣溫度過高導致四通閥內(nèi)部零件變形卡死或換向不靈。
