Summary of common faults and solutions of Roots blower!

  Roots Blower Rely on the synchronous gear at the rotor shaft end to keep the two rotors engaged. The concave curved surface on the rotor forms the working volume with the inner wall of the cylinder. During the rotation of the rotor, gas is sucked in from the suction port. When the rotor moves near the exhaust port, the instantaneous connection with the exhaust port is made. Because of the backflow of high pressure gas, the pressure in the working volume suddenly rises, and the gas is transported to the exhaust channel. The two rotors do not contact each other during operation, and they are sealed by tightly controlled clearance, so the discharged gas is not polluted by lubricating oil.

1、 Insufficient air volume. Cause of fault: the inlet filter is blocked. Treatment method: remove the dust and blockage of the filter, and replace it if necessary.
2、 The impeller is worn and the clearance increases. Treatment method: repair and adjust the clearance
3、 The belt slips. Treatment method: tighten the belt, increase the number of belts, and replace it if necessary. Cause of fault: excessive inlet pressure loss. Treatment method: adjust the inlet pressure to the specified value.
4、 Leakage of pipeline system. Treatment method: fasten the connectors and repair the leaking parts. Cause: the safety valve leaks. Treatment method: open the valve several times with a lifting wrench to flush away dirt
5、 The fan temperature is too high. The fault reason is that there is too much or too little oil in the oil tank. Treatment method: adjust the oil level of oil tank. Cause of fault: poor oil quality. Treatment: Replace with new lubricating oil.
       

Use case of Roots blower

6、 The pressure rise increases. Treatment method: check the inlet and exhaust pressure and load, and reduce the pressure difference
7、 Filter or muffler is blocked. Treatment method: remove foreign matters.
8、 The impeller is excessively worn with large clearance. Treatment method: repair the clearance.
9、 The inlet temperature is high due to poor ventilation and high indoor temperature. Treatment method: open a vent to maintain good ventilation and reduce the room temperature.
10、 The running speed is too low, and the belt slips. Treatment: increase the rotating speed to prevent the belt from slipping.
11、 Overload of Roots blower motor: fault cause: excessive inlet resistance. Treatment method: clean the inlet filter.
12、 Treatment method for pressure increase: check the exhaust pressure and load, and reduce the pressure difference.
13、 There is friction between the impeller and the cylinder wall. Treatment method: adjust the clearance.
14、 The rotating speed of the fan is too high. Treatment method: replace the proper pulley.
The above are the common faults of Roots blower and their solutions. I believe you will understand them after reading them. I hope they will help you.
