Interpreting the 30 Factors That Cause Platemaking Equipment Failure

The pre-printing plate equipment has a high proportion of faults due to external factors. The reasons are many, and the solution must be determined according to the actual situation. In the course of maintenance, the author summarizes the 30 factors that are likely to cause the failure of plate-making equipment. These factors are inextricably linked with equipment failures. Of course, there may be some other important factors that may not be included. However, careful analysis of these factors can ensure that The normal operation of equipment and the rapid release of faults are briefly described below:

1. Dust: A plate prepared especially for later generations, photocopying equipment, is precision equipment, dust is the biggest natural enemy for such machines, dust can cause great harm to the equipment, so in daily maintenance The most important thing is cleaning.

2. Oil pollution: Due to the influence of precision mechanical friction, almost all equipment uses different types of lubricants. In the long-term lubrication process, affected by temperature, dust, and the powder generated during friction, the oil is extremely likely to form oil and directly cause mechanical obstruction and local temperature increase, which is also an important factor causing mechanical failure of the device.

3. Contamination: Contaminated items include two aspects, one is oil contamination, and the other is contamination caused by the combination of debris or accumulated debris and moisture in the air during equipment operation. Initial contamination does not generally have a major impact on the equipment, but long-term accumulation can easily cause damage to the equipment locally, such as dirty spots on the monitor.

4. Raw material adhesion: The raw material adhesion performance is more serious in the development machine and the proofing machine. It is the development process of the developing machine. After the chemical reaction between the film surface material and the developing solution, it is easy to adhere to each roller. If the proofing ink is improperly cleaned, it can easily adhere to the ink roller and the rubber roller. Therefore, maintaining regular cleaning is a good way to solve the problem of raw material adhesion.

5. Wear: Most of the wear occurs in the parts where machinery is often active, such as various plate-making equipment bearings and active screw clamps. The most effective way to reduce wear is to add more oil.

6. Vibration: Vibration will not only cause the equipment itself to fail, but also may cause problems in the quality of the product. After effectively ensuring the correct installation of the equipment, it is also necessary to constantly check its stability and level.

7. Looseness: Most of the loosening causes are caused by external factors, such as the vibration of the equipment. During daily maintenance, it is necessary to check the tightness and fixation of each screw.

8. Leakage: refers to the internal parts of the prepress equipment due to aging or impact, resulting in protection fluid leakage, the component temperature rise burned, such as SCREEN P-641-FW copy of the circulating cooling water inside the lamp.

9. Corrosion: Most non-metal devices with volatile liquids have varying degrees of damage. Substances that are attached to the surface of the device and are not removed in time are the main cause of corrosion.

10. Creep: The process of creep is generally not easy to express because creep can be expressed both mechanically and electronically. Therefore, minor changes in equipment parameters should be taken into account during the inspection of equipment.

11. Stress deformation: Stress deformation is a physical phenomenon that occurs more often at work in equipment. After the work is completed, the lack of timely adjustment of the equipment is an important factor affecting the deformation of the mechanical and circuit board slots of the equipment.

12. Scratches: The equipment in operation is scratched by the collision of external objects. Scratches can directly cause major equipment failures and may also affect the quality of the product, such as roller scratches on electric extensions.

13. Cracks: The main cause of cracks is the long-term impact of equipment or gravity. In the event of a crack, under normal circumstances, do not repair, in order to prevent secondary cracking equipment damage.

14. Fever: After the electronic device is powered on, there is usually a phenomenon of heat generation. After the metal mechanical friction, there is also a phenomenon of heat. Electronic heating requires an auxiliary heat sink, while metal machinery relies on its own thermal conduction to reduce heat dissipation. Daily equipment testing needs to pay attention to the degree of heating of the equipment.

15. Abnormal sound: In the course of operation of the machinery and equipment, the sound of the normal sound emitted by the influence of many factors such as the heat wear, etc., needs to be shut down and overhauled in time, otherwise it is easy to expand the fault.

16. Short circuit: Short circuit is often accompanied by the damage of other components, and the short circuit itself is due to component aging, human error, etc. After a short circuit occurs, do not immediately power, need to carefully check the cause of such failure, and then conduct power test .

17. Insufficient insulation: The aging of the equipment and the heat during operation can cause the insulation performance of the insulation to decrease. Poor insulation can short-circuit the device. Be as generous as possible when controlling and replacing components or circuits.

18. Continuity obstruction: It is the phenomenon that no current passes through the movable element after the guide body or electronic switch, relay and other components are affected by voltage, current, and contact resistance. Continuity barriers can generally be tested by turning on the power.
