Daily maintenance is routine maintenance, all by the operator daily implementation. The first level of maintenance is based on the operator, maintenance workers with into the maintenance.
The second level of maintenance is based on professional maintenance personnel, the operator to participate in the maintenance. Above the second level of maintenance in order of small repairs, item repair, overhaul, remodeling. Daily warranty, first warranty, second warranty constitutes the three-tier maintenance system. The three-tier maintenance system is a combination of professional management and maintenance and group management and group repair of an equipment maintenance system.
The specific content of the three levels of maintenance, including routine maintenance (commonly known as routine maintenance), the first level of maintenance (referred to as the first insurance) and the second level of maintenance (referred to as the second insurance).
Equipment "three maintenance system" is to rely on the masses, give full play to the enthusiasm of the masses, the implementation of mass management, equipment maintenance and maintenance of effective ways.
First, "three maintenance system" content: 1, daily maintenance: before and after the shift by the operator to carefully check the equipment, wipe all parts and lubricants, so that the equipment is often kept neat, clean, lubricated, safe. Equipment failure in the class, give timely exclusion, and carefully do a good job of shift handover records.2, the first level of maintenance: operator-based, maintenance workers counseling, according to the plan for the partial disassembly of the equipment and inspection, cleaning of prescribed parts, dredging oil, piping, replacement or cleaning of oil line, linoleum, oil filter, adjust the equipment parts with the gap, tighten all parts of the equipment.
3, three-tier maintenance: maintenance workers mainly, included in the overhaul plan of the equipment, part of the equipment dismantling inspection and repair, replacement or repair of worn parts, cleaning, oil change, inspection and repair of the electrical parts, local restoration of accuracy, to meet the minimum requirements of the processed parts. Second, "three good" "four will" content The implementation of the "three-tier maintenance system", the operator must make the equipment to achieve "three good "" four will "requirements: 1," three good "content: (1) tube good: consciously abide by the system of fixed person fixed machine, with the operating license to use the equipment, do not mess with other people's equipment, good tools, accessories, not lost, damaged, placed neatly, safe and secure! Damage, placed neatly, safety guards are complete and useful, lines, pipes intact. (2) with good: the equipment does not run with disease, not overloaded, not big machine small, fine machine rough. Compliance with operating procedures and maintenance procedures. Careful care of equipment to prevent accidents.(3) repaired: according to the planned maintenance time, downtime repair, and actively cooperate with the maintenance workers, to participate in the equipment of the second level of maintenance work and large and medium repairs after the completion of the acceptance test work.
2, "four will" content :
(1) will use: familiar with the structure of the equipment, master the technical performance of the equipment and operating methods, know the processing technology, the correct use of equipment.
(2) will maintain: correctly according to the lubrication charts, refueling, oil change, keep the oil circuit is smooth, oil line, felt, oil filter clean, clean, keep the equipment inside and outside the clean, no dirt, no dirt, paint see the color of the iron to see the light. According to the provisions of the first level of maintenance work.
(3) will check: understand the equipment precision standards, will check the precision inspection items related to the machining process, and can make appropriate adjustments. Will check the safety protection and insurance devices.?
(4) will troubleshooting: can not be the usual sound, temperature and operation, found that the abnormal condition of the equipment, and can judge the abnormal condition of the parts and causes, and take timely measures to remove the fault. Accidents, participate in the analysis, clear causes of accidents, lessons learned, and make preventive measures.
Expanded Information:
Requirements for the maintenance of the equipment:
1, neat
Tools, workpieces, accessories placed in a neat, toolbox, Shelf should be placed reasonably, neatly, equipment and safety guards are complete, a variety of signs should be complete and clear, lines, pipes should be installed neatly, safe and reliable.
2, clean
Equipment inside and outside the clean, no dust, no black rust; the movement of the pieces of oil, no hair, bruises, scratches; parts of the water leakage, leakage, oil leakage; chips, garbage clean.
3, lubrication
On time, according to the quality and quantity of refueling and oil change, to keep the oil label visible, oil tank, oil pool, cooling box should be clean, no iron debris, oil pots, oil check, oil cups, oil nozzles complete, oil felt, oil line clean, oil pump pressure is normal, the oil circuit is smooth, the bearings of all parts of the lubrication is good.
And mechanical equipment failure characteristics often have diversity, the application of mechanical equipment is designed to improve the efficiency of mechanical production, and for mechanical equipment, it is often necessary to be in operation for a long time, which makes it easy to produce corrosion, wear and fatigue under the influence of a variety of factors over a long period of time, and other issues.
The purpose of equipment maintenance:
Most of the testing equipment belongs to the precision instruments, not only require test operators will use, but also to understand the basic principles of the instrument, the use of precautions, the instrument's storage environment, so that the failure rate of the instrument will be reduced.
Equipment maintenance can maintain the stable state of the equipment and the use of durable, so as to ensure that the production schedule, efficiency, product quality and stability to reduce production costs, and improve the utilization of equipment, reduce the cost of equipment.
In the daily maintenance, only "strict" word at the head, correct, reasonable use, careful maintenance, careful management, and effectively strengthen the use of the pre-use, the use of the process and the use of the inspection in a timely manner, serious, high-quality elimination of hidden defects, troubleshooting.
To do a good job in the use of operational records, to ensure the correctness and completeness of the original information, vouchers. Require operators to be able to equipment for the existence of common failures, put forward suggestions for improvement.
And with the maintenance workers, take appropriate measures to improve the technical condition of the equipment, reduce the frequency of failure and eliminate accidents, to achieve the purpose of maintenance.
