同正負(fù)環(huán)室結(jié)合處泄漏有關(guān)。無法用旋緊螺栓的方法消除泄漏，于是拆下節(jié)流裝置更換密封墊片，然后發(fā)現(xiàn)孔板變形。同天氣有關(guān)。孔板流流量計節(jié)流裝置本來無泄漏現(xiàn)象，由于天氣暴冷，西北風(fēng)勁吹，引起正負(fù)環(huán)室結(jié)合處泄漏。同節(jié)流裝置處絕熱保溫不佳有關(guān)。保溫良好的節(jié)流裝置未出現(xiàn)泄漏現(xiàn)象。將上述相關(guān)線索聯(lián)系起來可對孔板變形原因作出推理分析。節(jié)流裝置設(shè)計計算時，孔板外徑與環(huán)室配合處的間隙留得足夠大是假定孔板和環(huán)室溫度相同，但實際上不可能相同，孔板被環(huán)室包圍著，而且有高溫流體為其提供熱量，所以溫度高，得到充分膨脹。

一般來說，羅茨蒸汽壓縮風(fēng)機的轉(zhuǎn)速在98～145r/min，普通離心蒸汽壓縮風(fēng)機的轉(zhuǎn)速在6～9r/min，而單級高壓離心風(fēng)機的高轉(zhuǎn)速可達(dá)3r/min。當(dāng)然，對于羅茨風(fēng)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(fēng)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(dá)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(dǎo)閥的閥芯不能動作；由于外部原因，先導(dǎo)閥部變形，造成閥芯不能動作；先導(dǎo)閥毛細(xì)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(jìn)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(dá)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(dǎo)致四通閥內(nèi)部零件變形卡死或換向不靈。
