What are the common faults and solutions of rolling shear type spiral duct fan manufacturers?

1. The touch screen of rolling shear type spiral air duct machine displays hydraulic overload alarm and flickers

Methods: check whether the system pressure of the hydraulic station of the rolling shear spiral air duct machine is too high, remove the cover plate of the mechanical and electrical air box of the rolling shear spiral air duct, and manually reset the thermal relay.

2. The rolling shear spiral air duct machine does not lift the knife when punching small holes

Practice: the solenoid valve of the rolling shear type spiral air duct fan may be blocked by debris, so the rolling shear spiral air duct fan can be cleaned up.

3. The rolling shear spiral air duct fan does not stop discharging or does not discharge.

Exercise: check whether the photoelectric switch of the roller shear type spiral air duct blower bracket is damaged or the connecting line is disconnected, and check and replace it.

4. After the rolling shear type spiral air duct fan is put into operation, the plate size is not stable.

Exercise: check the encoder and signal line of the rolling shear type spiral duct fan and repair them in time.

5. The cutting knife of the rolling shear spiral air duct fan cannot move.

Exercise: check whether the circuit or equipment of rolling shear spiral duct fan is damaged, and replace and repair it in time.
