When you encounter an industrial dust collector that
cannot be started, you should first check whether there is any problem with the power line, including the power switch and each connection end buckle. If there is no problem, it may be a problem with the industrial dust collector. Because of its high speed, small size, and large starting torque, it can adapt to a wide range of power supply voltage fluctuations, and must use brushes and commutators. If the contact is not good, it will cause the brush or commutator to wear out too fast, or even burn out, and eventually the motor will not start, so we should detect and analyze the fault of the motor and deal with it properly. The main measures are as follows:
1. If the fuse is blown, replace it with a new one.
2. If the power cord is in poor contact or the motor leads are loose, the power source should be connected.
3. If the power switch is damaged, replace the power switch.
4. If the motor is damaged, replace it with a new one. Industrial dust collectors have
cleaned our environment and produced fewer occupational diseases. Its power is indispensable. However, due to the high power of industrial dust collectors and the high frequency of use, it is inevitable that some faults will occur during use. What causes the industrial dust collectors to malfunction? Today I will help you analyze it.
1. The noise is too large: it may be caused by severe bearing wear, deformation or displacement of the impeller shaft, loose fasteners, wear of the motor, loose or damaged fan blades, etc.
2. Decreased suction: It is caused by the failure of the motor, the wear of the brushes, the dampness of the dust filter, the clogging of the hose and the dust suction or exhaust port, the dust collection room full of dust, and the poor interface seal.
3. The case is charged: This is caused by the aging of the power cord, which causes ground leakage and the internal circuit of the vacuum cleaner to contact the case.
4. Fuse connection blowout: It is caused by short circuit of power cord, plug, socket, short circuit of motor coil, short circuit of internal wiring of vacuum cleaner.
5, motor overheating: caused by continuous working time is too long, brushes and commutator wear sparks are too large, dust room is full of dust, dust on the filter is too much.
