醫藥冷庫設備有限公司和大家講解制冷機組維修常見的兩種故障現象：

1、故障現象：機組壓力低 ·實際用氣量大于機組輸出氣量；·放氣閥故障(加載時無法關閉)；

1, fault phenomenon: system with low pressure, actual gas is greater than the output volume; , purge valve fault (load cannot close);
進氣閥故障；·液壓缸故障；·負載電磁閥(1SV)故障·最小壓力閥卡死；
Intake valve fault; , hydraulic cylinder fault; Load, electromagnetic valve (sv) 1 fault, the minimum pressure valve stuck;
用戶管網有泄漏；·壓力設置太低；·壓力傳感器故障(控制機組)；
User pipe network leakage; , the low pressure setting; (control unit), a pressure sensor failures;
壓力表故障(繼電器控制機組)；·壓力開關故障(繼電器控制機組)；·壓力傳感器或壓力表輸入軟管漏氣。
Pressure gauge failure (relay control unit); Pressure switch, a fault (relay control unit); , pressure sensor or pressure gauge input tube leakage.
2、故障現象:機組油耗大或壓縮空氣含油量大 ·冷卻劑量太多，正確的位置應在機組加載時觀察，此時油位應不高于一半；
2, fault phenomenon: unit fuel consumption big or the oil content of compressed air, coolant is too much, correct position should be observed when the unit load, the oil level shall not be higher than half;
回油管堵塞；·回油管的安裝(與油分離芯底部的距離)不符合要求；機組運行時排氣壓力太低；·油分離芯破裂；·分離筒體內部隔板損壞；·機組有漏油現象；冷卻劑變質或超期使用。

Back to the tubing plug; , return pipe installation (and oil separator at the bottom of the distance) is not in conformity with the requirements; Unit operation exhaust pressure is too low. Oil separator, burst; Separation, cylinder internal partition damage; Unit, oil leakage phenomenon; Coolant spoiled or extended use.
