Heidelberg HD102V four-color offset press failure repair example (c)

Fault 9: Causes of rotten paper transfer from paper to tooth: 1 The whole row of teeth is uneven, not on the same straight line; 2 Locating pins at the row end are loose or shearing, and the teeth are skewed; 3 The paper is not delivered at the correct time, not "zero Even "transfer.
Repair: 1 The entire row of dental pad leveling; 2 Replace the positioning of the row of teeth, pinning, tooth alignment; 3 Adjust the position of the open cam plate is appropriate; 4 If the cam plate is seriously worn, adjustment is invalid, there are two methods can be Repair: A check the wear, calculate the amount of wear, first draw and sample template, weld repair or repair after the fitter repair; B mapping processing, wear-resistant surface treatment (available EDM strengthening, nitriding, etc.).
Fault 10: The reason for the rising of the delivery table is that: the end of the receiving balance spring is broken and the chain is wrong;
Repair: 1 Reattach the disconnected spring, or change the spring; 2 reset the chain, balance the two ends of the paper table.
Fault 11: Roller cannot be pressed off (one or more sets)
Causes: 1 Circuit failure; 2 The clutching piezoelectric magnet in the operating side shield is stuck, broken or burned.
Repair: 1 to eliminate circuit failures; 2 remove the shield, symptomatic treatment (A. eliminate obstacles blocking, B. remove the burned electromagnet,
Rewind the coil; C. Select domestic-made replacement electromagnets, equipped with small accessories such as plates, rods, springs, model MQl-5111, suction 3Kg, voltage 220V, working stroke 25mm).
Fault 12: Cause of duster failure: 1 bad powder sprayer, part number 00.780.3029; 2 powder spray tube is blocked; 3 bad powder spray pump.
Repair: 1 repair or replace the potentiometer, optional replacement parts; 2 nozzle discharge plug, symptomatic treatment; 3 maintenance and repair dust pump.
Fault 13: Sustained delivery of the motor does not turn Reasons: 1 circuit failure; 2 Loose motor mounting screws, skewed stuck; 3 motor or transmission is blocked by dirt; 4
Motor burned or bearing damaged.
Repair: 1 check the circuit and the motor, remove the fault; 2 adjust the motor position, tighten the base screw; 3 maintenance and repair motor and transmission; 4 replace rotten loss bearing.
Fault 14: The delivery slow conveyor belt is broken, part number 00.580.0744
Causes: Aging rubber aging, fatigue cut off.
Repair: 1 Adhesive bond; 2 purchase domestic replacement parts or according to West Germany D/N3770 standard processing.
Fault 15: Damage to the conveyor belt, pulley, and pin shaft: Long-term fatigue damage.
Repair: 1 adhesive bonding; 2 mapping processing, pulley optional nylon, plastic or bakelite, pin 45 steel selection.
Fault 16: Large spring on the swing paper feeder Broken Cause: Fracture fatigue.
Repair: 1 using similar specifications of the pressure spring or TT402 machine pressure spring trimmed the appropriate contingency, emergency; 2 mapping processing.
