Reasons and Solutions of High Noise in Positive Displacement Blower

Some customers reflect that the positive displacement blower has a lot of noise in the using , why is the noise so large? Is the quality problem of the product itself? Sometimes it is not because of the quality problem of blower, it is possible because the daily maintenance work is not done, now the positive displacement blowers are all low noise, if there is high noise, the positive displacement blower has been a failure. Then what is the cause?

Now I analyze them for you:
1: the pressure is raising caused by pipe blockage, then we need to clean or replace the pipeline
2: the belt cover improper installation causes vibration, then check and reload belt cover on it;
3: the motor bearing wear, replace the new bearings;
4: the dust into positive displacement blower cause damage of the rotor, at this time to repair the rotor; (this needs professional personal, do not disassemble by yourself.)
5: no lubrication oil will lead to high noise, then check the lubrication system;
6: bad lubrication, should always wash the drip nozzle and oil filter;
7: pulley loose, fastening the thimble;
8: V-belt slip, adjust the belt tension.
