安全性：不注意安全即会产生灾难腐蚀性介质：宜选用塑料王电磁阀和全不锈钢；对于强腐蚀的介质必须选用隔离膜片式。例CD-F.Z3CF。中性介质，也宜选用铜合金为阀壳材料的电磁阀，否则，阀壳中常有锈屑脱落，尤其是动作不频繁的场合。氨用阀则不能采用铜材。性环境：必须选用相应防爆等级产品，露天安装或粉尘多场合应选用防水，防尘品种。电磁阀公称压力应超过管内高工作压力。适用性：不适用等于花钱买费物，还要添麻烦。介质特性1.1质气，液态或混合状态分别选用不同品种的电磁阀，例ZQDF用于空气，ZQDFY用于液体，ZQDF2(或-3)用于蒸汽，否则易引起误动作。ZDF系列多功能电磁阀则可通通于气.液体。好订时告明介质状态，安装用户就不必再调式。质温度不同规格产品，否则线圈会烧掉，密封件老化，严重影响寿命命。质粘度，通常在5cSt以下。若超过此值，通径大于15mm用ZDF系列多功能电磁阀作特殊订货。

了解螺杆式冷水机的主要工作原理之后，下面我们为大家解析螺杆式冷水机组常见的故障问题，供大家参考。高压故障：压缩机排气压力过高，导致高压保护继电器动作。压缩机排气压力反映的是冷凝压力，正常值应1.4~1.6MPa，保护值设定为2.MPa。若是长期压力过高，会导致压缩机运行电流过大，易烧电机，还易造成压缩机排气口阀片损坏，而应该做的自然是控制好压缩机排气压力的大小在安全范围之内。产生高压故障的原因如下：冷却水温偏高，冷凝效果不良；冷却水流量不足，达不到额定水流量；冷凝器结垢或堵塞；制冷剂充注过多；制冷剂内混有空气、氮气等不凝结气体；电气故障引起的误报。

一般来讲，系统的极限真空度比系统的工作真空度低2%，比前级泵的极限真空度低5%。被抽气体种类与抽气量?检查确定工艺要求的抽气种类与抽气量。因为如果被抽气体种类与泵内液体发生反应，泵系统将被污染。同时必须考虑确定合适的排气时间与抽气过程中产生的气体量。真空容积检查确定达到要求的真空度所需要的时间、真空管道的流阻与泄漏。考虑达到要求真空度后在一定工艺要求条件下维持真空需要的抽气速率。选用真空泵时需要注意事项：真空泵的工作压强应该满足真空设备的极限真空及工作压强要求。
