对于油压控制的能量调节系统，其主要原因有：滑油压力过低。(一般为轴承间隙过大和泵间隙过大引起)，可通过旋紧油压调节阀来解决;卸载油缸的活塞严重漏油，油路阻塞;油缸与活塞或其它机构卡阻;电磁阀动作不灵，或铁芯有剩磁。

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.

制冷机组长时间停机后，系统中制冷剂是环境温度下的饱和状态，因为环境温度的变化，饱和温度也在发生变化，润 滑油对制冷剂的溶解度随之发生变化，当溶解度变小时，会有制冷剂析出。

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.

析出有两种方式：气相和液相，制冷剂液态比重约为1.2,比油重，会沉积在底部，随着环境温度变化而周期性的变化，底部液态的制冷剂越来越多，最后将油面抬高，使部分润滑油溢流离开油箱，导致“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、长时间停机时，保持油加热器电源不被中断，维持油温可防止失油;

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单独导管，利用联通器原理将积累在底部的制冷剂液体引回蒸发器，这样停机后因油箱底部制冷剂增多，油位至多只能上升至导管的水平转弯高度处，为避免导管内出现虹吸，导管需要设置防虹吸装置，这样可以在停机断电的情况下避免机组“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、机组油箱设计时考虑到足够空间和余量，防止油位抬高后发生溢流;

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