When the suction of the dust collector is small, it is necessary to check the operation and parameters of the equipment first, and then carry out professional consultation.

1. The pressure of the pulse valve is reduced, and it is necessary to climb to check whether the data of the air bag pressure gauge is normal.

2. The fan is reversed, the fan cable is incorrectly installed, or the fan, motor, or capacitor system is faulty. Electrical equipment needs regular inspection, cleaning and maintenance.

3. There are obstructions in the pipeline or dust collector, which affect the exhaust air volume. The air volume and noise of different suction tuyere of the pipeline are measured to eliminate the cause of the failure of the air regulating valve. Open the dust collector to check whether the cloth bag is damaged or dropped, and replace the cloth bag with the dust.

4. Open the valve to check whether water is discharged from the air bag drain pipe.
