The characteristics of Roots blower are that when the pressure is adjusted within the allowable range, the flow changes little, the pressure selection range is wide, and it has the characteristics of forced gas transmission. The medium does not contain oil during transportation. Simple structure, convenient maintenance, long service life and low vibration of the whole machine.
Replacement of lubricating oil. There are generally three management methods for the oil change of Roots blower:
Change the oil on time, that is, according to the specified time cycle. For example, change the oil every 3 months or so. As soon as the deadline comes, replace all the oil regardless of its quality. This method is simple and conservative, so it will cause waste and increase operating costs.
Change the oil according to the quality, that is, according to the performance of the lubricating oil. Once the oil quality index exceeds the allowable standard, it shall be replaced regardless of the service time. This method is economical, but it is difficult to judge accurately.
Change the oil on time and according to the quality, that is, refer to a certain oil change cycle, and change the oil according to the change of oil quality. For example, if there is less dust pollution, change the oil every 6 months or so, and if there is serious pollution, change the oil every 3 months or so. If the oil color becomes darker and turbid, and there are dirt deposits and solid particles, the oil change period should be further shortened.
1. When the lubricating oil of roots blower bearing is in normal use, it should be replaced at least once every six months. When it is used for the first time, it should be done after about 200 hours of operation. The second oil change should be done in 1~2 months. After that, the lubricating oil should be checked once a week. If the lubricating oil does not deteriorate, the oil change can be extended to 2~4 months, The specified brand of lubricating oil must be used for replacement, and the old oil in the oil tank must be completely drained and cleaned before new oil can be filled.
2. When changing the oil, drain the oil in the oil tank before injecting new oil. It is better not to add the oil on the basis of the old oil, because the oil in the oil tank will be too dirty and thick after a long time. This will affect the operation of Roots blower. Pay attention to the position of the oil mirror during daily inspection. Once the oil level is found to be less than half of the oil mirror, it should be supplemented in time. If the Roots blower is short of oil for a long time, the motor will burn down in serious cases.
3. If the oil is replenished, it is usually the equipment with oil leakage. Generally, the equipment in good condition rarely has the problem of obvious oil level drop, and there is no need to replenish oil during the normal oil change period.
4. The order of changing gear oil for Roots blower: first remove the gear oil, then inject new gear oil. The first time: one month after starting and running, the second time after three months, and the second time after long-term running every six months. Pay attention to the oil level daily and replenish it in time.
5. Evaluation of lubricating oil quantity of Roots blower: the oil quantity of each model of Roots blower can check the gear side oil mirror at any time, and keep the oil level between the center line during shutdown. If the oil level is lower than the middle position, lubricating oil must be added in time; If the oil level is higher than the middle position, the oil temperature will be high, the exhaust body will spray oil, and the engine body will leak oil.
I believe that after reading the above, you should also know how to change the oil of Roots blower. I hope it will help you.
