The oil change of Roots blower is an important maintenance measure to ensure the normal operation of the equipment. The following are the detailed steps and precautions for oil change:
1、 Oil change cycle
1. New machine first oil change
The new machine needs to have its first oil change after one month of operation, and its second oil change after three months.
After long-term operation, it is recommended to replace the gear oil every 3-6 months, and the specific cycle can be adjusted according to the quality of the oil and the usage environment.
2. Daily maintenance
Check the oil level and quality before starting each day to ensure that the oil level is in the middle and upper position of the oil mirror.
If the oil level is found to be lower than the middle line of the oil mirror, it should be replenished in a timely manner; Long term lack of oil may lead to motor burnout.
2、 Oil change steps
1. Preparation work
Turn off the fan power and ensure that the equipment stops running and is in a stationary state.
Prepare cleaning containers for collecting old oil, as well as tools such as filters and clean fabrics.
2. Discharge old oil
Find the gear oil discharge port at the bottom or side of the fan, unscrew the discharge screw, and drain the old oil.
When collecting old oil, it is necessary to avoid polluting the environment, and waste oil should be disposed of according to environmental protection requirements.
3. Clean the gearbox
Use a filter to remove impurities and dirt from the gearbox to ensure internal cleanliness.
Check if the sealing components of the gearbox are intact, and replace them promptly if they are damaged.
4. Add new oil
Choose gear oil that meets the equipment requirements (such as 220 medium load gear oil or ISO VG32/46, etc.).
Slowly inject new oil from the oil injection port, keeping the oil level in the middle of the oil mirror to avoid being too high or too low.
5. Check and restart
Close the discharge outlet, clean up the spilled oil, and ensure the appearance of the equipment is clean.
Restart the fan and check the oil level and temperature after running for a period of time to confirm that the equipment is operating normally.
3、 Precautions
1. Oil selection
Special gear oil must be used to avoid mixing lubricants of different models or brands.
Choose the appropriate oil viscosity (such as ISO VG32 or VG46) based on the device model and usage environment.
2. Operation
Wear protective gloves when changing oil to avoid skin contact with the oil.
Waste oil should be stored properly, away from sources of fire, to prevent environmental pollution.
3. Regular inspection
Check the oil level and quality every week. If the oil turns black, emulsifies, or contains excessive impurities, it needs to be replaced in advance.
Before restarting after a long-term shutdown, it is necessary to check the oil level and replenish new oil.
4、 Common problems and solutions
1. Abnormal oil level
Excessive oil level may cause an increase in oil temperature, oil leakage, or fuel injection; If the oil level is too low, it needs to be replenished in a timely manner.
2. Deterioration of oil quality
If the oil turns black, has an odor, or contains metal shavings, it should be replaced immediately and the equipment wear should be checked.
3. Oil leakage treatment
Check if the seal and oil pipe connection are loose or damaged, and replace the seal if necessary.
5、 Summary
The oil change of Roots blower must be strictly carried out in accordance with the operating procedures, selecting suitable oil products and regularly checking the oil level and quality. Through standardized maintenance and upkeep, the service life of the equipment can be effectively extended to ensure the stable operation of the fan.
