Introduction: Sanitary pads are an inseparable commodity in modern civilization, but even the production staff do not know much about the machinery that produces sanitary pads. If there is a problem with the electrical equipment of sanitary pads machinery, how should the operator repair it?
For the faulty sanitary pads machinery electrical equipment, do not rush to do it, you should first ask about the process of the fault and the phenomenon of the fault. For unfamiliar equipment, you should be familiar with the circuit principle and structural characteristics first, and abide by the corresponding rules. Before disassembly, be fully familiar with the function, position, connection method and relationship with other surrounding components of each component.
You should first check the sanitary pads machinery for obvious cracks and defects, understand its maintenance history, service life, etc., and then check the inside of the machine. Before dismantling, the surrounding failure factors should be sorted out, and the device can be disassembled only after it is determined to be an internal fault. Otherwise, blind disassembly may cause the equipment to be damaged more and more.
Only after confirming that the mechanical parts are fault-free, conduct electrical inspections. When checking the circuit fault, the detection instrument should be used to find the fault location. After confirming that there is no bad contact fault, the operation relationship between the circuit and the machine should be checked in a targeted manner to avoid misjudgment.
When the sanitary pads equipment is not powered on, judge the quality of the equipment buttons, contactors, thermal relays and fuses, so as to determine the fault location. Power-on test, listen to the sound, measure parameters, judge faults, and finally carry out maintenance. For example, when the motor is out of phase, if the three-phase voltage value cannot be judged, you should listen to the sound and measure each phase-to-ground voltage separately before judging which phase is defective.
For equipment with heavy pollution, first clean its buttons, wiring points, and contact points, and check whether the external control keys are out of order. Many failures are caused by dirt and conductive dust blocks, which are often eliminated once cleaned.
The failure rate of the power supply part accounts for a high proportion of the entire faulty equipment, so repairing the power supply first can often get twice the result with half the effort.
The failures caused by the quality of assembly parts or other equipment failures generally account for about 50% of common failures. The special faults of the equipment are mostly soft faults, which must be measured and maintained by experience and instruments.
Don't rush to replace the damaged parts first, and then consider replacing the damaged parts after confirming that the peripheral equipment circuit is normal.
9. DC first, then AC
During maintenance, the static operating point of the DC circuit must be checked first, and then the dynamic operating point of the AC circuit.
sanitary pads machinery The price of each unit is very expensive. If there is a problem with the electrical equipment, it must be repaired in strict accordance with the standard principles to avoid damage expansion and economic damage.
