style="font-size:14px;">定期檢查配件靈敏度</span><span style="font-size:14px;">此外，工業(yè)制冷機(jī)組還需要定期檢查吸氣側(cè)、過(guò)濾器用的壓差繼電器、排氣側(cè)壓力繼電器、油壓與冷卻水用的壓力、繼電器和油壓繼電器等配件的運(yùn)作是否靈敏，是否存在故障，多注意保養(yǎng)。</span> </p>

style="font-size:14px;">冷庫(kù)庫(kù)溫過(guò)高，經(jīng)檢查發(fā)現(xiàn)，兩庫(kù)溫度只有-4℃ ～0℃ ，兩庫(kù)的供液電磁閥處于打開狀態(tài)。壓縮機(jī)啟動(dòng)比較頻繁，轉(zhuǎn)換用另一臺(tái)壓縮機(jī)工作時(shí)情況并沒有好轉(zhuǎn)，而回氣管上卻有很厚的結(jié)霜。進(jìn)人這兩個(gè)庫(kù)檢查發(fā)現(xiàn)，蒸發(fā)盤管上均結(jié)有很厚的霜，除霜后情況有所改善，這時(shí)壓縮機(jī)的啟動(dòng)次數(shù)有所減少，庫(kù)溫也有所降低，但還不理想。后來(lái)，檢查到低壓控制器動(dòng)作的上下限值，發(fā)現(xiàn)被誤調(diào)為0.11—0.15NPa(表壓，下同)，即壓力為0.11MPa時(shí)停止壓縮機(jī)，壓力為0.15Pa時(shí)啟動(dòng)壓縮機(jī)，對(duì)應(yīng)的蒸發(fā)溫度范圍約為-20℃一18℃ ，顯然這個(gè)調(diào)定太高了，且幅差值也過(guò)小。因此，對(duì)低壓控制器上下限重調(diào)，調(diào)整后其值為：0.05—0.12MPa，對(duì)應(yīng)的蒸發(fā)溫度范圍約為-20℃一l8℃，之后，重新啟動(dòng)系統(tǒng)，工作恢復(fù)正常。</span> </p><p> <span style="font-size:14px;">制冷機(jī)組故障--高低壓控制器的調(diào)定值有誤</span> </p> <p> <span style="font-size:14px;">制冷設(shè)備使用制冷劑為R22，高壓斷電壓力(上限)多選為表壓1.7一1.9MPa。低壓繼電器壓力(下限)可取設(shè)計(jì)蒸發(fā)溫度減去5℃(傳熱溫差)后所對(duì)應(yīng)的冷劑飽和壓力，但一般不低于表壓0.01 MPa。低壓開關(guān)的調(diào)節(jié)幅差一般為0.1～0.2MPa。有時(shí)壓力控制調(diào)定值的刻度不太精確，實(shí)際動(dòng)作值應(yīng)以調(diào)試測(cè)得值為準(zhǔn)。測(cè)試低壓控制器時(shí)應(yīng)慢慢關(guān)小壓縮機(jī)吸人截止閥，注意吸人壓力表的指示值，壓縮機(jī)停車和重新啟動(dòng)時(shí)的指示值即為低壓控制器的上限和下限。試驗(yàn)高壓控制器可慢慢關(guān)小壓縮機(jī)排出截止閥，讀出排出壓力表在壓縮機(jī)停下時(shí)的讀數(shù)，即為高壓斷開壓力。試驗(yàn)前要證實(shí)壓力表可靠;排出閥不應(yīng)全關(guān)，以保安全。</span>

奉行“知人善任、人盡其才”的人才理念。昆明制冷機(jī)組廠家</p><p style="text-indent:25px">過(guò)硬品質(zhì)，用實(shí)力說(shuō)話。昆明制冷機(jī)組哪家公司好</p><p> <span style="font-size:14px;">制冷機(jī)組壓縮機(jī)，是機(jī)組中非常關(guān)鍵的部件，壓縮機(jī)的好壞直接關(guān)系到機(jī)組的穩(wěn)定性。如果壓縮機(jī)發(fā)生故障.由于壓縮機(jī)的安裝精度要求較高，一般都需要請(qǐng)廠方來(lái)進(jìn)行維修。</span> </p> <p> <br /> </p> <p> <strong><span style="font-size:14px;">1、更換潤(rùn)滑油</span></strong> </p> <p> <span style="font-size:14px;">制冷機(jī)組在長(zhǎng)期使用后，潤(rùn)滑油的油質(zhì)變差，油內(nèi)部的雜質(zhì)和水分增加，所以要定期的觀察和檢查油質(zhì)。一旦發(fā)現(xiàn)問(wèn)題應(yīng)及時(shí)更換，更換的潤(rùn)滑油牌號(hào)必須符合技術(shù)資料。</span> </p> <p> <strong><span style="font-size:14px;">2、更換干燥過(guò)濾器</span></strong> </p> <p> <span style="font-size:14px;">干燥過(guò)濾器是保證制冷劑進(jìn)行正常循環(huán)的重要部件。由于水與制冷劑互不相溶，如果系統(tǒng)內(nèi)含有水分，將極大可能影響機(jī)組的運(yùn)行效率，因此保持系統(tǒng)內(nèi)部干燥是十分重要的，干燥過(guò)濾器內(nèi)部的濾芯必須定期更換。</span> </p> <p> <strong><span style="font-size:14px;">3、安全閥的校驗(yàn)</span></strong> </p> <p> <span style="font-size:14px;">冷水機(jī)組上的冷凝器和蒸發(fā)器均屬于壓力容器，根據(jù)規(guī)定，要在機(jī)組的高壓端即冷凝器本體上安裝安全閥，一旦機(jī)組處于非正常的工作環(huán)境下時(shí)，安全閥可以自動(dòng)泄壓，以防止高壓可能對(duì)人體造成的傷害。所以安全閥的定期校驗(yàn)對(duì)于整臺(tái)機(jī)組的安全性是十分重要的。</span> </p> <p> <br /> </p> <p> <strong><span style="font-size:14px;">4、冷凝器和蒸發(fā)器的清洗</span></strong> </p> <p> <span style="font-size:14px;">水冷式冷凝器的冷卻水由于是開式的循環(huán)回路，一般采用的自來(lái)水經(jīng)冷卻塔循環(huán)使用。</span> </p> <p> <strong><span style="font-size:14px;">5、制冷劑的充注</span></strong> </p> <p> <span style="font-size:14px;">如沒有其他特殊的原因，一般機(jī)組不會(huì)產(chǎn)生大量的泄漏。</span> </p> <p> <br /> </p> <span style="font-size:14px;"></span> <p> <br /> 昆明制冷機(jī)組哪家公司好</p></p><br /><p>文章來(lái)源地址:
