對于油壓控制的能量調節系統，其主要原因有：滑油壓力過低。(一般為軸承間隙過大和泵間隙過大引起)，可通過旋緊油壓調節閥來解決;卸載油缸的活塞嚴重漏油，油路阻塞;油缸與活塞或其它機構卡阻;電磁閥動作不靈，或鐵芯有剩磁。

For oil pressure control system, the main reasons are as follows: low oil pressure. (usually bearing clearance is too large and the pump gap caused by excessive), which can be solved by tightening the oil pressure regulating valve; the piston cylinder unloading serious oil spill, the oil blocking; the cylinder and piston or other blocking; solenoid valve action is ineffective, or core remanence.

制冷機組長時間停機后，系統中制冷劑是環境溫度下的飽和狀態，因為環境溫度的變化，飽和溫度也在發生變化，潤 滑油對制冷劑的溶解度隨之發生變化，當溶解度變小時，會有制冷劑析出。

The refrigerator a long time after the shutdown, the refrigerant system is saturated at ambient temperature, because the change of environment temperature, saturation temperature is also changing, the solubility of lubricating oil on the refrigerant is changed, when the solubility decreases, there will be precipitation of refrigerant.

析出有兩種方式：氣相和液相，制冷劑液態比重約為1.2,比油重，會沉積在底部，隨著環境溫度變化而周期性的變化，底部液態的制冷劑越來越多，最后將油面抬高，使部分潤滑油溢流離開油箱，導致“跑油”。

The precipitation in two ways: gas phase and liquid phase, the liquid refrigerant accounted for about 1.2, is heavier than oil, will be deposited in the bottom, with the change of environment temperature and the cyclical change, more and more at the bottom of the liquid refrigerant, the oil surface elevation, the left part of the oil overflow tank, resulting in "oil spill".

1、長時間停機時，保持油加熱器電源不被中斷，維持油溫可防止失油;

1, long time downtime, keep the oil heater power supply is not interrupted, maintain the oil temperature can prevent oil loss;

2、另外可在油箱底部引出單獨導管，利用聯通器原理將積累在底部的制冷劑液體引回蒸發器，這樣停機后因油箱底部制冷劑增多，油位至多只能上升至導管的水平轉彎高度處，為避免導管內出現虹吸，導管需要設置防虹吸裝置，這樣可以在停機斷電的情況下避免機組“跑油”

In addition, 2 can separate the catheter at the bottom of the oil tank, the device will lead to the accumulation of Unicom principle in the bottom of a liquid refrigerant evaporator, so stop after the tank at the bottom of the refrigerant level increased, at the height of oil level can only turn up to the catheter, in order to avoid the catheter catheter siphon, need to set up an anti siphon device, which can avoid the oil unit "in the run down power case"

3、機組油箱設計時考慮到足夠空間和余量，防止油位抬高后發生溢流;

3, the unit fuel tank design takes into account enough space and margin, to prevent oil level after the overflow;
