How to ｒｅｐｌａｃｅ the vacuum pump oil of the oil filter?

The replacement cycle of vacuum pump oil and the precautions when replacing it are key to ensuring the vacuum pump's normal operation and extending its service life. The following is a detailed discussion of the replacement cycle and precautions for vacuum pump oil.

The replacement cycle of vacuum pump oil mainly depends on several factors: working environment, equipment manufacturer's recommendations and oil quality. In a clean, dry working environment with an operating temperature below 100°C, the replacement cycle of vacuum pump oil can usually be extended to every 500 to 2000 working hours or every six months.

However, in a harsh working environment, vacuum pump oil may need to be replaced every 500 working hours. In addition, if the color of the vacuum pump oil turns dark brown, it should also be replaced in time.

When replacing vacuum pump oil, there are several points to note:

1. Make sure the vacuum pump has stopped running and drain the medium in the pump body. This is to avoid hot oil spraying or splashing when changing oil.

2. Unscrew the drain screw and drain the oil. Pay attention to the oil level when draining the oil to avoid excessive oil draining.

3. Inject new vacuum pump oil to the center of the oil mark. When refueling, use a special refueling tool and avoid using containers containing other oils or solvents.

4. Restart the vacuum pump to ensure that there is no abnormal sound, check the oil level and oil quality, and ensure normal operation. After starting the vacuum pump, observe its operation to ensure that there is no abnormal sound or vibration.

In addition, there are some other precautions:

1. When replacing the vacuum pump oil, make sure that the oil filling window is clean, avoid sun exposure and open-air storage, and prevent moisture and dust from mixing.

2. When taking or filling oil, pay attention to the small rain around the barrel cover must be removed to prevent debris from mixing into the oil and causing wear of the pump.

3. Vacuum pump oils of different brands and varieties cannot be mixed, and new and old oils cannot be mixed. This is to avoid chemical reactions between different oils and affect the performance of the vacuum pump.

4. The vacuum pump should try to avoid extracting solvents, water vapor and corrosive gases. If it must be used, it should be checked and changed frequently to ensure the normal operation of the vacuum pump.

5. When inspecting the pump, you must clean the various parts of the pump with solvents or cleaning agents and dry the parts to completely remove the residue and moisture in the pump to avoid affecting the performance and service life of the pump.

In short, regular replacement of vacuum pump oil and compliance with the above precautions are the key to ensuring the normal operation of the vacuum pump and extending its service life. In actual operation, it should be carried out in accordance with the equipment manual and operating procedures to ensure safety and effectiveness. If you are not sure how to operate or encounter problems, it is recommended to seek help from professionals.
