安全性：不注意安全即會產生災難腐蝕性介質：宜選用塑料王電磁閥和全不銹鋼；對于強腐蝕的介質必須選用隔離膜片式。例CD-F.Z3CF。中性介質，也宜選用銅合金為閥殼材料的電磁閥，否則，閥殼中常有銹屑脫落，尤其是動作不頻繁的場合。氨用閥則不能采用銅材。性環境：必須選用相應防爆等級產品，露天安裝或粉塵多場合應選用防水，防塵品種。電磁閥公稱壓力應超過管內高工作壓力。適用性：不適用等于花錢買費物，還要添麻煩。介質特性1.1質氣，液態或混合狀態分別選用不同品種的電磁閥，例ZQDF用于空氣，ZQDFY用于液體，ZQDF2(或-3)用于蒸汽，否則易引起誤動作。ZDF系列多功能電磁閥則可通通于氣.液體。好訂時告明介質狀態，安裝用戶就不必再調式。質溫度不同規格產品，否則線圈會燒掉，密封件老化，嚴重影響壽命命。質粘度，通常在5cSt以下。若超過此值，通徑大于15mm用ZDF系列多功能電磁閥作特殊訂貨。

了解螺桿式冷水機的主要工作原理之后，下面我們為大家解析螺桿式冷水機組常見的故障問題，供大家參考。高壓故障：壓縮機排氣壓力過高，導致高壓保護繼電器動作。壓縮機排氣壓力反映的是冷凝壓力，正常值應1.4~1.6MPa，保護值設定為2.MPa。若是長期壓力過高，會導致壓縮機運行電流過大，易燒電機，還易造成壓縮機排氣口閥片損壞，而應該做的自然是控制好壓縮機排氣壓力的大小在安全范圍之內。產生高壓故障的原因如下：冷卻水溫偏高，冷凝效果不良；冷卻水流量不足，達不到額定水流量；冷凝器結垢或堵塞；制冷劑充注過多；制冷劑內混有空氣、氮氣等不凝結氣體；電氣故障引起的誤報。

一般來講，系統的極限真空度比系統的工作真空度低2%，比前級泵的極限真空度低5%。被抽氣體種類與抽氣量?檢查確定工藝要求的抽氣種類與抽氣量。因為如果被抽氣體種類與泵內液體發生反應，泵系統將被污染。同時必須考慮確定合適的排氣時間與抽氣過程中產生的氣體量。真空容積檢查確定達到要求的真空度所需要的時間、真空管道的流阻與泄漏。考慮達到要求真空度后在一定工藝要求條件下維持真空需要的抽氣速率。選用真空泵時需要注意事項：真空泵的工作壓強應該滿足真空設備的極限真空及工作壓強要求。
