If there is a problem with the door and window processing equipment, it should not be repaired blindly. The fault should be eliminated first, and the problems that occur during production should be investigated one by one. Many users are not very familiar with the internal structural characteristics of the equipment, and should follow the corresponding rules. Before disassembly, it is necessary to fully understand the function, position, connection method, and relationship with other surrounding components. In the absence of an assembly diagram, disassembly should be carried out while sketching, And mark it.

 The maintenance of equipment needs to follow the principle of "from the outside to the inside". Check whether there are obvious cracks or defects on the outside of the equipment, and then inspect its interior. Before disassembling, queue up the surrounding fault factors to determine that it is an internal fault before disassembling. Otherwise, blind disassembly may cause the door and window processing equipment to deteriorate over time. First, mechanical parts should be repaired before electrical parts. Only after confirming that there are no faults in the mechanical parts, electrical inspections should be carried out to check for circuit faults, Testing instruments should be used to locate the faulty area, confirm that there are no poor contact faults, and then check the operation relationship between the circuit and the machinery in a targeted manner to avoid judgment errors.

Do not power on the equipment first, check if there are any problems with the buttons, circuits, etc. of the equipment, in order to determine the location of the fault. Conduct a power on test, listen to its sound, measure parameters, determine the fault, and then carry out maintenance. For example, when the three-phase voltage value of the motor is missing, if it cannot be determined by measuring the three-phase voltage value, listen to its sound and measure each phase to ground voltage separately to determine which phase is missing. Clean it first and then repair it. For heavily polluted broken bridge aluminum door and window equipment, clean its buttons, wiring points, and contact points first, and check whether the external control keys are malfunctioning. Many faults are caused by dirt and conductive dust blocks, and once cleaned, faults are often eliminated.
