Fault judgment of plate making before the most pri

Pre press plate making fault judgment

pre press plate making equipment has a high proportion of faults caused by external factors. The reasons are various, and the solutions must also be determined according to the actual situation. In the process of maintenance, the author summarizes 30 factors that are easy to cause the failure of plate making equipment. These factors are inevitably related to the failure of the equipment. Of course, there may be some other important factors that may not be included, but a careful analysis of these factors will ensure the normal operation of the equipment and the rapid removal of the failure. The following is a brief description:

1 Dust: the equipment for making flat skull tissue with poor regeneration, especially the electrical separation and phototypesetting equipment in the later stage, is a precision equipment. Dust is the biggest natural enemy of this kind of machine, and dust can cause great damage to the equipment, so cleaning is the most important in daily maintenance

2. Oil pollution: affected by the friction of precision machinery, almost all equipment must use lubricants of different properties. In the long-term lubrication process, affected by temperature, dust and powder generated during friction, lubricating oil is very easy to form oil stains, which directly causes mechanical obstruction and local temperature rise, and is also an important factor for mechanical failure of equipment

3. Filth: filthy objects include two aspects, one is oil contamination, and the other is filth formed by the combination of impurities in the air or accumulated impurities and water during the operation of the equipment. Generally, the initial pollution will not have a great impact on the equipment, but the long-term accumulation is easy to cause local damage to the equipment, such as the pollution shift on the display

4. Raw material adhesion: the raw material adhesion is relatively serious in the developer and proofer. It is formed after the chemical reaction between the film surface material and the developer during the development process of the developer, and it is easy to adhere between the cots. Proofing ink can easily adhere to ink rollers and rubber rollers if it is not cleaned properly, so regular cleaning is a good way to solve the adhesion of raw materials

5. Wear: most of the wear occurs in the frequently active parts of the machine, such as bearings of various plate making equipment and active screw clips. The most effective way to reduce wear is to add more oil

6. Vibration: vibration will not only cause equipment failure, but also may cause product quality problems. After effectively ensuring the correct installation of the equipment, its stability and level should be regularly tested

7. Looseness: most of the looseness is caused by external reasons, such as the vibration of the equipment. In the process of daily maintenance, pay attention to the tightness and fixation of each screw

8. Leakage: refers to the leakage of protective fluid inside the accessories of prepress equipment due to aging or impact, which increases the temperature of components and burns them out, such as the circulating cooling water in screenp-641-fw copier lamp

9. Corrosion: most volatile liquids damage non-metallic equipment to varying degrees. The main cause of corrosion is the substances attached to the surface of the equipment and not removed in time

10. Creep: the process of creep is generally not easy to show, because creep can be shown in both mechanical and electronic aspects, so in the process of detecting equipment, attention should be paid to small changes in equipment parameters

11. Stress deformation: stress deformation is a physical phenomenon that occurs more often in working equipment. After the project is completed to let the construction developers, design, construction, supervision, testing and other units and consumers better understand the polyurethane insulation products and their characteristics, the failure of the equipment to be adjusted in time is an important factor affecting the deformation of equipment machinery and circuit board slots

12. Scratches: scratches are caused by the impact of external objects on the running equipment. Scratches can directly cause major failures of the equipment and may also affect the product quality, such as scratches on the drum of the electric extension

13. Crack: the main reason for the crack is that the equipment is affected by large pressure or gravity for a long time

the failure of prepress plate making equipment accounts for a high proportion due to external factors. The reasons are various, and the solutions must also be determined according to the actual situation. In the process of maintenance, the author summarizes 30 factors that are easy to cause the failure of plate making equipment. These factors are inevitably related to the failure of the equipment. Of course, there may be some other important factors that may not be included, but a careful analysis of these factors will surely ensure the normal operation of the equipment and the rapid removal of the failure.

Dust is the biggest natural enemy for such machines. Dust can cause great damage to the equipment, so cleaning is the most important in daily maintenance

2. Oil pollution: affected by the friction of precision machinery, almost all equipment must use lubricants of different properties. In the long-term lubrication process, affected by temperature, dust and the powder generated during friction, the lubricating oil is very easy to form oil stains, which directly causes mechanical obstruction, local temperature, and the continuous improvement of people's living standards. It is also an important factor for mechanical failure of equipment
