為了(le)保(bao)(bao)證(zheng)客戶購買(mai)的(de)冷(leng)(leng)卻水循環機(ji)安(an)(an)全穩定連續運行，在(zai)冷(leng)(leng)卻水循環機(ji)上安(an)(an)裝了(le)各種控制保(bao)(bao)護(hu)器，如高低壓(ya)保(bao)(bao)護(hu)、壓(ya)縮機(ji)過(guo)熱(re)過(guo)載保(bao)(bao)護(hu)、壓(ya)縮機(ji)延遲啟動保(bao)(bao)護(hu)等。

1. 高壓控(kong)制(zhi)器:位于冷水機(ji)壓縮(suo)(suo)機(ji)的排(pai)氣管上，當壓力超過(guo)設定(ding)值(zhi)時，高壓控(kong)制(zhi)器切(qie)斷電路，使壓縮(suo)(suo)機(ji)停(ting)止運(yun)行，從而實現自動(dong)保(bao)護。高壓設定(ding)值(zhi)I

2. 油(you)(you)溫(wen)(wen)(wen)控(kong)制(zhi)器(qi):油(you)(you)溫(wen)(wen)(wen)直(zhi)接影響潤滑油(you)(you)的粘度(du)，從而影響潤滑油(you)(you)的分離效果。因此，使(shi)用(yong)溫(wen)(wen)(wen)度(du)控(kong)制(zhi)器(qi)來控(kong)制(zhi)其油(you)(you)溫(wen)(wen)(wen)。當油(you)(you)溫(wen)(wen)(wen)高于70℃時，油(you)(you)溫(wen)(wen)(wen)控(kong)制(zhi)器(qi)可使(shi)壓縮機停止運(yun)行。

3. 低(di)(di)壓(ya)控制器:位于(yu)(yu)壓(ya)縮(suo)機的吸入管上，當壓(ya)力(li)低(di)(di)于(yu)(yu)設定值時(shi)(shi)，低(di)(di)壓(ya)控制器切斷電(dian)(dian)路，當壓(ya)力(li)高于(yu)(yu)設定值時(shi)(shi)，電(dian)(dian)路接(jie)通(tong)。低(di)(di)壓(ya)控制器可作為自動(dong)安全保護，防止(zhi)蒸(zheng)發壓(ya)力(li)過低(di)(di)時(shi)(shi)冷卻液結冰(bing);或防止(zhi)冷水機壓(ya)縮(suo)機在(zai)低(di)(di)吸入壓(ya)力(li)條件下(xia)運行(通(tong)常(chang)有故障)。
