1. Selection of silicone oil
Silicone oil is a high molecular organic compound made into a transparent viscous liquid. It has good lubricity, insulation, waterproofness, heat resistance and other properties, so it is widely used in the lubrication and sealing of various mechanical equipment. However, there are many types of silicone oil. For vacuum pumps, non-volatile and temperature-stable silicone oil should be selected as much as possible to avoid corrosion to the pump body or affect its vacuum efficiency.
2. Control of the amount added
After selecting the appropriate silicone oil, you need to pay attention to the control of the amount added. Generally speaking, the amount of silicone oil added should be controlled within 2% of the total volume inside the vacuum pump. Excessive addition of silicone oil will not only affect the efficiency of the vacuum pump, but may also cause the silicone oil to volatilize in the pump body and cause interference in vacuum work. Therefore, when adding silicone oil, you should pay attention to the control of the amount added to avoid excessive addition.
3. Precautions
In addition to the selection of silicone oil and the control of the amount added, the following matters need to be noted when adding silicone oil to the vacuum pump:
1. The silicone oil should be filtered to avoid impurities in the pump body from wearing and contaminating the pump.
2. The addition of silicone oil should be carried out when the pump body is emptied to avoid air mixing into the pump body, thereby affecting the vacuum efficiency of the pump.
3. The addition of silicone oil should be evenly distributed in the vacuum pump and should not be added to only one part of the pump.
4. After the silicone oil is added, the vacuum degree of the pump should be checked in time, and the stability of the vacuum degree should also be noted during operation.
4. Can silicone oil be added to the vacuum pump?
It can be added. However, the addition of silicone oil should be controlled, and the above matters need to be noted. If not handled properly, the addition of silicone oil may cause the efficiency of the vacuum pump to decrease, thereby affecting its use effect.
In short, the addition of silicone oil is an important part of vacuum pump maintenance. The correct addition method can effectively improve the working efficiency and life of the vacuum pump, but when adding, it is necessary to control the amount of addition, select the appropriate silicone oil, and observe the above precautions.
