Maintenance and common faults of electromagnetic clutch

Detailed content

In order to ensure the uninterrupted operation of the electromagnetic clutch, it is necessary to regularly maintain and maintain it:

1. Regularly check the tightness of the bolts, especially tightening the bolts of the electromagnet, the bolts of the electromagnet and the shell, the bolts of the magnetic yoke, the bolts of the electromagnet coil, and the wiring bolts.

2. Frequently add lubricant to the movable part of the electromagnetic clutch.

3. Regularly inspect the mechanical wear of movable components and remove dust, burrs, and dirt from the surface of electromagnetic components.

4. Regularly check the length of the armature stroke. Because during the operation of the clutch, the travel length of the armature will increase due to wear on the moving surface. When the length of the armature stroke cannot reach the normal value, adjustments must be made to restore the small gap between the brake surface and the rotary table. If the stroke length of the armature increases above the normal value, it may greatly reduce the suction force.

5. If the worn brake surface is replaced, the small gap between the brake surface and the rotary table should be adjusted appropriately.

During use, electromagnetic clutches may experience different malfunctions due to various factors. Electromagnetic clutch faults generally occur during startup, idling, and load, but they occur more frequently during startup, mainly manifested as inability to start or low input voltage to the electromagnetic clutch. The conventional input voltage is DC24V. And unstable power, slipping or high temperature, but there are also special situations.

So pay attention to the requirements when inputting voltage, and the elimination method is to check whether the input voltage is the required voltage for the electromagnetic clutch. The coil is short circuited, and when encountering this fault, it is usually replaced or repaired. It is recommended to modify the replaced or modified electromagnetic clutch circuit.

The operation is unstable, most likely due to unstable input voltage. The power of the detection power supply is about 1.5 times greater than the rated power of the electromagnetic clutch, and the voltage fluctuation is within the range of+-5%. The solution to unstable operation is to check the voltage condition and stabilize the voltage. Another situation is friction heating, which causes the coil to burn out or short-circuit due to heating.
