second, the use and maintenance of equipment

the more downtime and overhaul time of equipment, the less working time and the lower time availability; Conversely, the higher the availability of time. Our ideal is that the time interest rate of the required equipment is 100%. And urban social management and public services to achieve this goal, involving all aspects of factors, as far as the equipment itself is concerned, in addition to the quality of the composition period (including the reliability and durability of performance, the rationality of structure, the progressiveness and rationality of material selection, the degree of quality assurance of processing and manufacturing, etc.) is the basic condition, the correct and reasonable use of the service period, careful maintenance and careful management, It is the objective requirement to prolong the service life of equipment and the basic condition to give full play to the efficiency of equipment and improve the availability of time. Numerous examples in practical work show that the equipment of the same model and the same manufacturer put into production in the same period works under the same environmental conditions. Due to the advantages and disadvantages of use and maintenance conditions, the use effect varies greatly. This situation is not only between two equipment, but also in the same equipment. Due to the differences in the use and maintenance level of different operators and users, the use effect is also different. For example, a steel barrel seam welding machine in a factory, although it has been used for 20 years, has not been repaired in large or medium scale, the number of small repairs is not many, and the number of failures and downtime is very few. The equipment still maintains its due accuracy and performance, and its appearance is still new. The person who operates and uses this equipment is an old worker with high dedication and rich practical experience. His experience is to use it reasonably and maintain it carefully, so as to "cherish equipment as soldiers cherish weapons". Such cases exist in many enterprises. This shows that strengthening the use and maintenance of equipment can greatly reduce the maintenance downtime of equipment and improve the time availability on the premise of saving costs. Therefore, the focus of equipment service life management should be on the use and maintenance of equipment

first, use the equipment correctly

the basic conditions for the rational use of the equipment are: equip the equipment according to the process characteristics and actual needs of the enterprise's product production, make it complete, and make the layout reasonable and coordinated; Arrange the production tasks of the equipment according to the performance, bearing capacity and technical characteristics of the equipment; Select qualified operators; Formulate and implement laws and regulations on the use and maintenance of equipment, including a series of rules and regulations, to ensure that the operator uses and maintains the equipment according to the relevant technical data of the equipment; Have an objective environment to ensure that the equipment can give full play to its efficiency, including necessary protective measures and moisture-proof, anti-corrosion, dust-proof, shock proof measures; Establish and implement various systems for using equipment. The management of using equipment is based on these basic conditions. From the signing of the contract with the supplier to the withdrawal from production, through planning, organization, education, supervision and a series of measures, it can reduce wear, maintain the due accuracy, technical performance and production efficiency of the equipment, extend the service life, and make the equipment often in a good technical state to obtain the best economic effect

(I) reasonable allocation of equipment

reasonable allocation of equipment by the production department is the premise for correct and reasonable use of equipment, giving full play to efficiency and improving use effect. Reasonable allocation means that the enterprise should allocate and select equipment according to the actual needs of product process and technical requirements according to the production capacity, production nature and enterprise development direction. When equipping and selecting equipment, we should pay attention to the following points:

(1) we should consider the complete set of main production equipment and auxiliary production equipment. Otherwise, the equipment will not adapt to each other, resulting in uncoordinated production arrangements and affecting the normal production

(2) the allocation of equipment should be coordinated in terms of performance and economic efficiency. With the change of product structure, the change of variety, quantity and technical requirements, as well as the promotion and application of new processes and new materials, the allocation proportion of various equipment should also be adjusted accordingly to make it suitable

(3) in the process of equipping equipment, it is forbidden to pursue "large and complete" and "small and complete". In an enterprise, when comprehensively planning, balancing and implementing the equipment capacity of each unit, the starting point should be to give full play to the maximum role and utilization effect of the equipment, and try to be centralized rather than decentralized

(4) if some special equipment can be improved or refitted by using existing equipment or solved by the innovation of a certain tooling fixture, do not purchase special equipment

(5) in equipping equipment, attention should be paid to improving the adaptability and flexibility of equipment processing. To meet the requirements of products with multiple varieties, small batches and short production period

(II) the use of new equipment

the use of new equipment should focus on the following main links:

1. The selection and training of operators

according to the technical performance and structural complexity of the equipment, select skilled workers who have a strong heart, have the corresponding cultural level and professional knowledge, and can study hard on technical business for training and learning. Nowadays, there are more and more electronic computer control equipment, multifunctional and efficient equipment, and program-controlled automation equipment. These equipment have advanced technology, complex structure, and high requirements for operation and use. It is difficult for operators to master and operate without certain culture and professional technical basic knowledge. Improper use will not only fail to give full play to the due efficiency of the equipment, but even damage the equipment. When selecting operators, they must go through:

(1) cultural knowledge and intellectual choice

(2) professional knowledge learning and assessment

(3) operation skill training

only after learning and training in the above three aspects, and passing all examinations and obtaining certificates, can you become a qualified equipment operator

2. Formulate operating procedures and maintenance rules

organize the formulation of safety operating procedures according to the technical requirements, performance, structural characteristics, operation and use specifications, adjustment measures, etc. specified in the equipment manual, and put forward the specifications of operation and use requirements to the operators, and organize learning, so that they can master and be familiar with the specific requirements and relevant regulations of the operation and use of the equipment. In the operating procedures and maintenance rules, the use scope, requirements, methods, operation and maintenance requirements of the equipment and other precautions should be specified

while formulating safety operation regulations, it is necessary to formulate maintenance rules. The contents of the equipment maintenance rules include various maintenance regulations and specific requirements for external maintenance and transmission systems, safety devices, lubrication systems, control systems, hydraulic systems, electrical control metering instruments, etc., and clearly specify the maintenance time

3. Clarify job responsibilities

for equipment used by one person, after clarifying the operator, its responsibilities must be clarified; If two or more people are using the equipment at the same time or one person operates the equipment with two or three shifts, the information of the company shall specify that the team leader is responsible for the maintenance of the equipment

(III) normal use process of equipment

the management of equipment in the use process should be closely combined with production management, process management and operation technology management, so as to manage and use it well. In the process of use, requirements:

1. Arrange production tasks reasonably according to the technical performance of the equipment

producers should arrange production tasks reasonably according to the performance, technical conditions, processing range, load capacity, etc. of the equipment. Do not overload or use the equipment beyond the scope; It is not allowed to compete for equipment in pursuit of output. Those that should be repaired should not be repaired or occupy the maintenance time of equipment. We should avoid the waste of equipment and energy caused by "big horse pulling small car"

2. Strengthen process management

whether the equipment is in good condition is the prerequisite for excellent process management and operation. However, the rationality of the process is assured that understanding our products will directly affect the state of the equipment. According to the data accumulated in the actual work of some enterprises, due to the unreasonable process, the wear speed and wear amount increase due to the increase of dynamic load, which shortens the repair cycle of the equipment by two thirds

3. Use the equipment correctly and reasonably

during the use of the equipment, workers should use the equipment correctly and reasonably according to the operation and use procedures specified in the relevant technical documents and materials of the equipment and the characteristics, technical requirements and performance of the equipment. In order to ensure the correct and reasonable use of the equipment, operators should be regularly organized to learn the theoretical knowledge of operation technology and carry out basic skill training; Regularly organize theoretical knowledge and practical operation assessment. Through this series of measures, they can achieve the "four excellencies": excellencies in equipment - familiar with equipment performance, structure, principle, maintenance, inspection and troubleshooting of general faults; Excellent in operation - skilled, accurate and well coordinated; Excellent quality - understand the process flow, and the processed products meet the specified quality requirements; Be competent in complex situations - have a certain knowledge of safety and prevention, be able to judge, prevent and deal with accidents, and prevent accidents from expanding and causing greater losses

during the use of the equipment, the operator must achieve "three good" (namely: management, use and maintenance) "Five don't" (that is, don't leave the work position with the machine on. When you have to leave, stop and cut off the power supply; don't violate the operating procedures, operate and use the equipment in strict accordance with the use requirements and specifications, and don't step on the equipment and kick the electrical switches and operating handles with your feet; don't use the equipment with overload and beyond the processing range. If necessary, you should report it in advance and get the consent of the relevant parties before using it; don't bring "disease" In case of any hidden trouble during operation, stop the machine for inspection in time, and do not continue to use it until the cause is found out and the hidden trouble is eliminated; Do not place workpieces, materials, tools, measuring tools, etc. on the machine, and it is strictly forbidden to knock on the guide rail and other parts of the equipment), so that the equipment can always be kept neat, clean, lubricated and safe

4. Strictly implement the system of fixed person and fixed machine

in the cause analysis of equipment accidents, "unskilled operation" is often caused by the operator's familiarity with the performance, operation requirements and technical specifications of the equipment. Therefore, when the operator platform needs to exchange and use other types of equipment due to work, he should first be familiar with the performance, structure, principle, operation specifications and use requirements of the equipment operated by the new post, and can only be operated after passing the examination. In order to meet the needs of "one specialty and many abilities" and organizing production, operators are allowed to apply for the operation of several different types and models of equipment at the same time, but these equipment can only be operated and used after passing the examination

5. Equip equipment inspectors and maintenance workers who are engaged in inspecting and supervising the use of equipment

in order to timely inspect and supervise the correct and reasonable use of equipment and the implementation of relevant rules and regulations such as equipment use and maintenance, the enterprise should set up a full-time "equipment inspector" to be responsible for formulating equipment operation procedures, maintenance rules, inspection Supervise but how to effectively use these waste materials for processing and manufacturing. Operators operate and maintain the equipment in strict accordance with the operating procedures and maintenance rules; Be responsible for solving technical problems in equipment maintenance and troubleshooting; Be responsible for the statistics and analysis of equipment faults and the accumulation of relevant data, and study the solutions to common faults and multiple faults; Be responsible for the storage, transmission and feedback of information during the service life of the equipment. Equipment inspectors should always
