What are the maintenance methods of Roots blower bearings? During the use of Roots blower, each component is in a state of loss. In order to reduce this loss, we need to do some maintenance for some important components to extend their service life. Today we will tell you how to maintain the bearings of Roots blower motor:

(1) When Roots blower is running, ensure that the oil level is between the two red lines of the oil level gauge.

(2) Too little oil will lead to poor lubrication of gears and bearings; Too much oil will cause the oil temperature to rise and damage the gear and other parts.

(3) The lubricating oil shall be of reliable and guaranteed quality. When filling the lubricating oil, the lubricating oil shall be added to the oil level gauge. After the blower and vacuum pump run, the oil level will drop slightly.

(4) When the blower and vacuum pump are driven by the intermediate shaft pulley, the bearing blocks at both ends of the intermediate shaft shall be filled with No. 2 general lithium base grease, and the filling amount shall be 1/2 - 1/3 of the free space of the bearing block.

(5) Roots blower is mainly composed of casing, wallboard and two rotors with impellers. Through the action of a pair of synchronous gears, the two rotors rotate at the same speed in the opposite direction, and rely on the The gap between the suction chamber and the exhaust chamber is basically isolated, and the air in the casing volume is driven by the rotation of the impeller to achieve the purpose of blowing.

Roots blower can control the air volume due to the frequency conversion control, and it is more intuitive and convenient to adjust the air volume of the blower to meet the production needs compared with the valve control; Due to the frequency conversion technology, the motor is soft Start, no starting current impact; The motor was started directly when the frequency converter was not used, and the starting current was up to 200-300A, which had adverse effects on the motor or the power grid. As the rotating speed of the fan is reduced to 60% of the original, the vibration frequency and noise of the fan pipe are greatly reduced, the mechanical life of the fan and motor bearing is extended, and the maintenance of the equipment is reduced.
