The speed is slower or not, or
The specific reasons are due to motor damage, line load, excessive load, or the pause button not bouncing back for calibration.
To address these common faults, it is necessary to replace the burnt out motor, check the circuit connection, rotate the guide rail slider of the travel switch to activate the power switch button switch, modify the body part of the power switch, and check for any blockages in the machine equipment body. If there are any, they must be removed.
When the button switch contact or toggle switch of the DC contactor is ineffective, the small screw of the guide rail slider is loose, or the support plate is moved, making it impossible for the guide rail slider or screw to move with the ball screw or, the transmission system of the limit switch transmission system is damaged, and the up and down keys of the key are stuck.
For common faults of such fast rolling shutter doors, these include replacing DC contactors, replacing toggle switches or metal springs, tightening screws to calibrate the support plate, replacing buttons, or replacing the transmission system of limit switches.
The zipper is not moving
The common causes of faults such as fast rolling shutter doors are jamming of the chain press frame, circular chains crossing the cross groove, and the ratchet and pawl not getting rid of the ratchet wrench.
Now that we have understood the common faults that cause such fast rolling shutter doors, let's grasp these: replacing lubricating grease and sorting out circular chains. Adjust the relative position between the ratchet, pawl, and press frame.
Electric motor oscillation or relatively high environmental noise
Common fault causes: brake disc imbalance or rupture; The brake disc is not tightened; Needle roller bearings lose oil or are ineffective; Gear meshing is not smooth, oil loss or severe damage; Motor noise or oscillation.
Solution: Replace the brake disc or change the balance again; Tighten the brake disc screws; Replace needle roller bearings; Mechanical and electrical maintenance of the motor bearing output end transmission system, lubrication or replacement; Inspect the motor and replace it if it is damaged.
