The failure to start the Roots blower may be caused by various reasons. Here are some common reasons and solutions:
1、 Power failure
Inspection content: Check if the power circuit is in good contact, if the fuse is blown, and if the voltage is stable.
Solution: Ensure that the power line is connected correctly and there are no open or short circuits; Replace the blown fuse; Check voltage stability and use a voltage regulator if necessary.
2、 Motor malfunction
Inspection content: Check whether the motor is damaged, whether the insulation is good, and whether the wiring is firm.
Solution: Check whether the internal parts of the motor are worn, whether the insulation layer is damaged, and whether the coil is open circuited; If necessary, replace or repair the motor.
3、 Control system malfunction
Inspection content: Check whether there are any abnormal prompts or fault indicator lights on the controller, and whether the start button, relay, circuit breaker and other equipment are working properly.
Solution: Based on the abnormal prompts or fault indicator lights on the controller, carry out corresponding repairs or replacements; Check and repair faults in equipment such as start buttons, relays, circuit breakers, etc.
4、 Mechanical malfunction
Inspection content: Check whether the bearings are damaged, whether the impeller is dusty or stuck, and whether the gears are stuck.
Solution: Disassemble and inspect the bearings. If damaged, replace or repair them; Clean the dust and debris on the impeller to ensure that it can rotate freely; Check the wear of the gears and replace them if necessary.
5、 System parameter setting error
Inspection content: Check whether the parameter settings of the fan control system are correct, such as whether the working mode, speed and other parameters meet the requirements.
Solution: According to the user manual of the fan, check and adjust the parameter settings of the control system to ensure that the parameters are correct and error free.
6、 Other faults
Air filter blockage: Clean or replace the clogged air filter.
Exhaust pipe blockage: Clean the blocked exhaust pipe.
There are foreign objects in the fan: Clean the dust and debris inside the fan to ensure that it is clean.
Fan rusting: Add an appropriate amount of clean gasoline for lubrication, and manually rotate it two to three times for lubrication; If rust is severe, rust removal treatment is required.
In summary, the reasons why the Roots blower cannot start may involve multiple aspects such as power supply, motor, control system, and machinery. When troubleshooting, these aspects should be checked one by one and corresponding solutions should be taken according to the actual situation. If the above methods cannot solve the problem, it is recommended to seek the help of technical personnel for further diagnosis and repair.
