Screw liquefaction unit

This post was last edited by sunjl1981 on 2013-1-6 23:46 Our factory uses a low-temperature liquefaction unit from Wuleng for chlorine liquefaction. The operation is relatively stable, but the screw machine carries a large amount of oil to the liquefier, and the oil needs to be drained frequently. Seniors, please analyze the reasons and give me some pointers, thank you#,, &
We also have this problem when using a large cooling unit. Since the engine capacity is now greatly improved, we adopt the method of draining oil in turns. There is no other better way.
Our factory also uses Wuhan. We have never encountered this situation and have never drained the oil. Could you please explain in detail? Drain oil from the liquefier?
It may be that the oil separation effect is not good. It is recommended to replace the filter element.
It may be that the injection pressure is high and the oil separation effect is not good.
reason: 1. High injection pressure ； 2. The oil separation effect is poor, check the filter. ； 3. When you first start driving, pay attention to the oil temperature rising before adding load.
We also encountered this situation with the screw unit we originally used. After a long period of analysis, we finally dissected the oil separator and found out that 1. Some oil separators cannot be disassembled. The filter component (steel mesh plus felt) inside is broken, and the oil is very large. Finally I replaced the separator. If it can be disassembled, it is more economical to replace the filter assembly. 2. In the separator, in front of the filter, there are generally three to four separate oil isolation chambers. There is an oil return pipeline at the bottom to the oil pump port, and there is a solenoid valve in the middle. Carefully check whether the valve can operate accurately, and whether the pipeline is blocked, causing poor oil return. This post was last edited by cqdcyxp on 2008-1-4 08:59 ]
Is the oil temperature controlled too low? It is best to be above 50 degrees. If it is too low, the oil will easily run out. This post was last edited by limingshuguang on 2008-1-6 09:30 ]
If the oil separation effect is poor, ultrafiltration can be used instead.
This phenomenon may also occur if you refuel too much.
The problem explained above is basically correct. Benyou and Wuleng machines have oil return systems. Just return oil. We used an ice wheel machine and one of them also had this problem. In the end, it was found that it was caused by too much oil.~~~~~~~~~~~
