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?
1. Mouth first, then hands
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.
2. External first then internal
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.
3. Mechanical first, then electrical
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.
4. static first, then dynamic
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.
5. Clean first, then repair
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.
6. Power first, then equipment
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.
7. General first, then special
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.
8. Peripheral first then internal
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.
10. Debug after failure
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.
