Abnormal sound of roots vacuum pump is caused by poor assembly, deviation of position between guide gear and rotor impinge the rotor, excessive entry pressure, overload or poor lubrication, damage to gear and bearing wear. Dismounting method: reloading; Adjust position to ensure clearance; Adjust and control inlet pressure; Change gear; Replace the bearings.



Root wind turbine factory tutor your roots blower maintenance fault elimination methods:


Abnormal sound of roots vacuum pump is caused by poor assembly, deviation of position between guide gear and rotor impinge the rotor, excessive entry pressure, overload or poor lubrication, damage to gear and bearing wear. Dismounting method: reloading; Adjust position to ensure clearance; Adjust and control inlet pressure; Change gear; Replace the bearings.



When there is insufficient pumping speed of roots vacuum pump, the reason and method of this situation are as follows: the pipeline permeability is not enough, then the pipeline permeability is increased. Lower the pumping speed of the front-stage pump, repair or replace the front-stage pump; The overflow valve leaks air and the overflow valve is cleaned. Above is the roots blower manufacturer on the elimination of trouble, hope to help you. Inspection and maintenance of roots blower in operation:



The repair and inspection of roots fan shall remove the motor from the base, open the front and rear end cover of the motor, take out the rotor, and screw all the end cover screws into the screw holes at both ends of the stator. Expose the stator to the sun for 12 hours at each end. Use a megometer to measure the insulation resistance between the windings and the casing no less than 20 megohm. If not, continue to expose in the sun to reach the standard.



The dissolved oxygen of roots blower is controlled at 2 ~ 4mg/L (read by the dissolved oxygen meter). At the initial stage of operation, due to the viscosity of the lubricating oil, there is too much noise and current, running for 10-20 minutes can disappear by itself. Flow cannot be adjusted by switching the valve. The fan is a volumetric compressor which changes the flow rate and shaft power by adjusting the speed. The pressure gauge switch is normally closed. If you need to measure the pressure, you can turn it on.
