For faulty milk assembly line equipment, it's not an emergency, you ought to first ask about the before and after process and therefore the phenomenon of the failure. For unfamiliar equipment, you ought to even be conversant in the circuit principle and structural characteristics, and follow the corresponding rules. Before disassembly, you want to be fully conversant in the functions, locations, connection methods, and relationships with other surrounding components of every milk assembly line . within the absence of assembly drawings, you ought to disassemble, draw sketches, and mark them.

Ten Principles of kit Maintenance for Pasteur Milk assembly line

1 Move your mouth first

For faulty milk assembly line equipment, don't answer the emergency, you ought to first ask about the before and after the failure and therefore the phenomenon of the failure. For unfamiliar equipment, you ought to even be conversant in the circuit principle and structural characteristics, and follow the corresponding rules. Before disassembly, you want to be fully conversant in the functions, locations, connection methods, and relationships with other surrounding components of every milk assembly line . within the absence of assembly drawings, you ought to disassemble, draw sketches, and mark them.

2 External first then internal

(1) Check the milk assembly line for obvious cracks and defects, understand its maintenance history, service life, etc., then check the within of the machine. Before dismantling, you ought to line up the encompassing failure factors, and you'll only dismantle after determining that it's an indoor failure. Otherwise, blindly dismantling, the equipment could also be repaired and worsened.

3 Machine first, electrical first

Only after confirming that the mechanical parts aren't faulty, the inspection of the milk assembly line is performed. When checking circuit faults, you ought to use testing equipment to seek out the faulty part, confirm that there are not any bad contact faults, then check the operating relationship between the road and therefore the machine to avoid misjudgment.

4 Static first, then dynamic

When the equipment isn't powered on, judge the standard of the buttons, contactors, thermal relays and fuses of the milk assembly line to work out the fault. Power on test, hear its sound, measure parameters, judge failure, and eventually perform maintenance. for instance, within the absence of phase of the motor, if the three-phase voltage value can't be distinguished, you ought to hear it and measure each phase voltage separately to work out which phase is flawed.

5 Clean first then repair

Clean the buttons, wiring points, and get in touch with points of the heavily polluted milk assembly line equipment and check whether the external control keys have failed. Many faults are caused by dirt and conductive dust blocks, and faults are often eliminated once cleaned.

6 Power first, then equipment

The failure rate of the facility supply part accounts for a high proportion of the whole faulty equipment, so it's often more efficient to repair the facility supply first.

7 Universal before special

Faults caused by the standard of assembly parts or other equipment failures generally account for about 50% of common failures. Most of the special faults of milk assembly line equipment are soft faults, which are measured and repaired by experience and instruments.

8 External first then internal

Don't rush to exchange damaged parts of the milk assembly line before you think about replacing the damaged parts of the milk assembly line when confirming that the peripheral circuit is normal.

9 DC first, then AC

During maintenance, the static operating point of the DC circuit must be checked before the dynamic operating point of the AC circuit.

10 Debug after failure

For the equipment of the milk assembly line that coexists with debugging and faults, the fault should be eliminated before debugging, and therefore the debugging must be performed under the premise of line speed of the milk assembly line.
