Ten Principles of Equipment Maintenance for Pasteur Milk Production Line

For faulty pasteurized milk production line equipment, it is not an emergency, you should first ask about the before and after process and the phenomenon of the failure. For unfamiliar equipment, you should also be familiar with the circuit principle and structural characteristics, and follow the corresponding rules. Before disassembly, you must be fully familiar with the functions, locations, connection methods, and relationships with other surrounding components of each pasteurized milk production line. In the absence of assembly drawings, you should disassemble, draw sketches, and mark them.

    Ten Principles of Equipment Maintenance for Pasteur Milk Production Line

1 Move your mouth first

For faulty pasteurized milk production line equipment, do not respond to the emergency, you should first ask about the before and after the failure and the phenomenon of the failure. For unfamiliar equipment, you should also be familiar with the circuit principle and structural characteristics, and follow the corresponding rules. Before disassembly, you must be fully familiar with the functions, locations, connection methods, and relationships with other surrounding components of each pasteurized milk production line. In the absence of assembly drawings, you should disassemble, draw sketches, and mark them.

2 External first then internal

(1) Check the pasteurized milk production line for obvious cracks and defects, understand its maintenance history, service life, etc., and then check the inside of the machine. Before dismantling, you should line up the surrounding failure factors, and you can only dismantle after determining that it is an internal failure. Otherwise, blindly dismantling, the equipment may be repaired and worsened.

3 Machine first, electrical first

Only after confirming that the mechanical parts are not faulty, the inspection of the pasteurized milk production line is performed. When checking circuit faults, you should use testing equipment to find the faulty part, confirm that there are no bad contact faults, and then check the operating relationship between the line and the machine to avoid misjudgment.

4 Static first, then dynamic

 When the equipment is not powered on, judge the quality of the buttons, contactors, thermal relays and fuses of the pasteurized milk production line to determine the fault. Power on test, listen to its sound, measure parameters, judge failure, and finally perform maintenance. For example, in the absence of phase of the motor, if the three-phase voltage value cannot be distinguished, you should listen to it and measure each phase voltage separately to determine which phase is defective.

5 Clean first and then repair

Clean the buttons, wiring points, and contact points of the heavily polluted pasteurized milk production 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 power supply part accounts for a high proportion of the entire faulty equipment, so it is often more efficient to repair the power supply first.

7 Universal before special

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

8 External first then internal

 Don't rush to replace damaged parts of the pasteurized milk production line before you consider replacing the damaged parts of the pasteurized milk production line when confirming that the peripheral device 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 pasteurized milk production line that coexists with debugging and faults, the fault should be eliminated before debugging, and the debugging must be performed under the premise of line speed of the pasteurized milk production line.
