For the bearing maintenance of Roots blower, we should always check the oil supply of the bearing lubricating oil of Roots blower. If there is oil leakage in the box, we can tighten the bolts of the end cover a little. If this is not enough, we may have to use new sealing packing.

When the bearing lubricating oil is in normal use, it should be replaced at least once in half a year. 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 to 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 to 4 months. The specified lubricating oil must be used when changing, The old oil in the oil tank shall be thoroughly drained and cleaned before new oil can be filled.

The lubricating oil of roots blower bearing should be replaced at least once every six months when it is used normally. When it is used for the first time, it should be replaced after about 200 hours of operation. The second oil change should be conducted in 1 to 2 months. After that, the lubricating oil should be checked once a week. If the lubricating oil is not deteriorated, the oil change can be extended to once every 2 to 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.

The lubricating oil in the bearing can effectively reduce the wear of the bearing. The smaller the wear, the longer the service life of the bearing. We once received a customer who used a Roots blower with broken bearings. The equipment was damaged for only one minute, and the whole equipment was scrapped. The reasons for bearing fracture really accumulated over the years.

How to maintain the motor bearing of Roots blower

The lubricating oil conducts the temperature, and the bearing will generate heat during rotation. These heat can be transmitted through the lubricating oil to dissipate the heat, thus playing the role of cooling the bearing; Due to the thermal conductivity of lubricating oil, the quality of lubricating oil needs to be considered. When the temperature of lubricating oil is too high, we need to check the lubricating oil regularly in time to ensure the quality of lubricating oil.

For example, lubricating oil will also be added to the gearbox, and the importance of lubricating oil in this part can be more reflected. If there is no lubricating oil, the gears will occlude with each other, and damage will occur in a short time. This kind of phenomenon is also likely to occur in the case of insufficient lubricating oil.

Bearing related spare parts include rings, rolling elements, and the use of lubricating oil can also effectively reduce the loss of these parts.

Note: The lubricating oil should not be too much or too little in use. It should be added according to the current situation of Roots blower. The gearbox with the largest use of lubricating oil for Roots blower is mainly used for heat conduction and lubrication. In the aspect of bearing lubrication, it also plays a major role in these two aspects. There are few bearing failures. If the operation and maintenance are improper, it is also easy to fail. Therefore, scientific and reasonable use can maximize the service life of roots blower.

If the fan bearing needs to be replaced, pay attention to the following:

Before installing the new bearing, the bearing and bearing housing must be very clean. Place the bearing in the oil with a temperature of about 70~80 ℃ and heat it before installing it on the shaft. Do not force assembly to avoid damaging the shaft.

I believe that after reading the above, you should also know how to maintain the bearings of Roots blower. I hope it will be helpful to you.
