Technical specification for large automobile coating production line
Abstract: the large-scale investment in large-scale coating production line planning and design, as well as equipment license installation and commissioning to acceptance is a very complex process. The preparation of coating technology requirements and the technical requirements of process equipment are of vital importance to the new coating equipment production line. This article mainly expounds this knowledge from the technical requirements of the new large automobile coating production line.
1 draw the purpose of coating technical requirements
(1) according to the coating technical requirements, determine the coating workshop machinery and automation equipment, these large quantities of process equipment to serve the mass production system for automobile body and / or sheet metal coating, meet the owners of properties, function, construction and quality of the equipment requirements.
(2) according to the technical requirements of the process equipment, to ensure that the equipment is successfully started in the shortest possible time during the debugging and starting of the equipment.
(3) refer to the checklist and test in the technical requirements of process equipment;
Test methods to evaluate all parts of the coating shop. The following three stages can be performed:
Stage 1 - tender review;
Stage 2 equipment inspection in supply plant;
Stage 3 - equipment test after installation.
(4) coating technical requirements to make the score of contractors and suppliers informed of these to support and maintain production and ensure safe production environment for all coating processes, facilities and features, and helps the equipment inspection and quotation. All key information is formatted in a unified manner so that the device is evaluated for comparison.
In these technical requirements, a variety of standardized technical conditions and standards are quoted, and specific articles, methods and equipment types can be drawn. These technical requirements can be used as the basis for technical proposals and basic tender documents. Deviations in standard construction methods and materials may be allowed in situations where the performance, function, economy and / or quality of the whole system are beneficial. For these deviations, the owner shall provide written documents prior to construction. Before submitting the cost proposal to the general contractor, the contractor is responsible for approving the deviation document. In addition to the owner's approval, function, safety and the quality of the equipment provided, the Contractor shall also be responsible for the implementation of the legal requirements. The ultimate objective is to provide the contractor with the complete equipment of the process, equipment and installation within the scope of this project, and comply with these technical requirements and comply with the requirements of the owners.
2 overall requirements
2.1 security
Paint operations and equipment perform the highest safety standards during their operations and maintenance. Monitor all safety inspection circuits and / or ensure safe working conditions. The contractor must implement the enterprise's requirements regarding safety, maintenance, energy control and published technical requirements. All equipment shall comply with the enterprise energy saving plan and the specific requirements of the site. All site works must strictly carry out on-site safety plan.
2.2 noise
Noise requirements - based on the noise requirements of the equipment purchased.
2.3 maintainability
On the basis of the expected use and operating conditions of the equipment, all equipment shall be repairable under the technical and operational personnel of the general factory. The following design standards shall be used to handle maintenance matters:
• be able to approach parts level;
Structural interchangeability and modularity;
The use of industrial grade and commercially available components;
Adopt standard parts, fasteners, fittings, hoses, etc.;
• use standard tools and test equipment;
Adopt reliable equipment;
Least maintenance equipment required;
• quick identification and location of faults (diagnostics);
• the ability to isolate faults locally in a component or subsystem so that the system will continue to function;
Quick regulation and calibration;
Avoid special training;
Eliminate the potential for false attire;
Ergonomics.
The repair of each automatic subsystem shall be repaired using the general tools and specialties of the assembly plant at no more than 2H during the period of active repair.
No maintenance is required during the 5000h run time. All maintenance, service, and replacement of parts in the 5000h running time shall be clearly documented.
2.4 silicon free equipment
All mounting materials must be free of silicon. It must be warned that no form of silicon containing material or lubricant is allowed in the plant facilities. Even a tiny amount of silicon can be harmful to the car's finishing process. This regulation applies to the equipment that is manufactured and installed in the bidder's or his sub contractor's factory. Silicon is not allowed in the manufacturing process. Special items to be monitored include lubricants in valves (especially PVC valves), Guan Daoqi, wire lubricants, seals, lubricants, sprays for lubrication and water proofing, and artificial lotions. All PVC valves and fittings using seals and many non plastic valves are usually made of the above. The supplier shall provide a written certificate indicating that the products supplied to the assembly plant are not silicon. Once the parts or materials are found contaminated, the structures that may be damaged must be replaced at their own expense. The contractor or bidder shall obtain a written certificate or test analysis form from each supplier or subcontractor to indicate that there is no silicon in the shipment. Once the parts or materials delivered to the owner are found to be contaminated by silicon, the contractor must replace the damaged structures at his own expense or eliminate the pollutants at his own expense.
2.5 quality assurance
Qualified suppliers must have effective technical and management systems
