　　Sichuan Roots Blower Manufacturers: Tell me about several root causes of Roots blower motor damage

The 1. motor is damaged by external damage. For example, the motor is out of phase and the wiring head is loose and short-circuited due to fan vibration. Water seepage or moisture return in distribution box or motor leads to reduction of insulation resistance. Aging of wires of machinery and equipment; Excessive dust intervention; The working standard voltage is wrong, and the working voltage is constantly too high or too low. Such situations may affect the normal operation of Roots blower motor. When Roots blower is working, the ambient temperature of the motor will rise greatly, as a result of motor damage, the general quality of the motor may be damaged within more than ten minutes, worse is the power supply and distribution system phase failure, many fan control switch is locked or fully automatic start, a power failure after the re-distribution phase failure safety accident, it is likely to burn several motors. Therefore, the Roots blower in use, carefully check the indicators after the normal restart, can reduce the common fault.

2. the Roots blower is overweight, the motor will be damaged. There are two connection methods between the Roots blower and the motor. One is the direct connection of the coupling. Because the Roots blower equipment and the flow working pressure characteristic points are more concentrated and the motor speed ratio is different, the export and flow working pressures are different, so adjusting the speed ratio can change the total flow. Therefore, the Roots blower also has a more common interface method-belt connection. When the Roots blower is stuck due to various reasons, the driving force given by the motor cannot normally push the blower, then the motor power of the blower exceeds the output power of the motor. If the excess is larger, the probability of motor damage is higher. When the Roots blower is running normally, the motor driving force is very suitable, but when the blower is stuck, the frictional resistance is much higher than the motor work, which leads to motor damage. Such things generally belong to equipment failure, it is generally closely related to the engine. For example, the problem of the centrifugal impeller of the Roots blower occurs when the centrifugal impeller wheel locks up, causing the motor to burn.

The variable pressure value of the fan is marked on the factory nameplate of the 3. Roots blower, which indicates the acceptable frictional resistance of the Roots blower under the output power of the motor. Roots blower sucks into the cyclone, through the mandatory promotion of the stator after the cyclone pressure change, export system software. When the friction resistance of the system is much higher than the variable pressure value of the machine, there will be insufficient driving force. When the friction resistance exceeds the variable pressure value, the output power of the motor is lacking, which will be reflected in the burning of the motor at the beginning, and the electromagnetic coil will be burned out during normal use., The motor is damaged.

If the fan model is not selected correctly, it is necessary to re-select the model. Therefore, it is very important to select a moderate model and pair it with a suitable output power motor. When the fan pipe is blocked, the frictional resistance will exceed the range of variable pressure values. The fan pipe must be fully cleaned. For example, the reverse check valve will suddenly expand the frictional resistance of the Roots blower and cause the motor to burn. These are more common motor damage.
