Electric ball valve series maintenance and repair

First, maintenance of electric ball valve equipment

The maintenance of the equipment through general methods such as wiping, sweeping, lubricating and adjusting to maintain and protect the construction machinery performance and technical condition of the equipment is called equipment maintenance. There are four main requirements for equipment maintenance:

(1) Clean and clean the equipment inside and outside the whole mine. There is no oil on the sliding surfaces, screws, racks, gear boxes, oil holes, etc., and no oil leakage or air leakage occurs on all parts. The chips, debris, and dirt around the equipment Mechanical engineers must clean up;

(2) Neatly arranged tools, accessories, and workpieces (products) should be placed neatly. Pipes and lines must be organized. <BR> (2) Lubrication is good. Timely refueling or oil change, constant oil, no dry friction, normal oil pressure The oil standard is bright and the oil path is unimpeded. The oil quality meets the requirements of Tianjin Machinery, and oil guns, oil cups and linoleum are clean;

(4) Safety Observe the safety operation rules, and do not overload the equipment. The safety equipment of the equipment will be complete and reliable, and the unsafe factors will be eliminated in time.

The maintenance content of the equipment generally includes daily maintenance, regular maintenance, periodical mechanical inspection and precision inspection in Hangzhou, and equipment lubrication and cooling system maintenance are also an important part of equipment maintenance.

The daily maintenance of equipment and washing machines is the basic work of equipment maintenance and must be institutionalized and standardized. Regular maintenance work on the equipment to work to develop a fixed quota and material consumption quota enrichment of civilian machinery, and the assessment of the fixed amount, equipment maintenance and repair work should be included in the workshop contract responsibility system assessment content. Periodic inspection of the equipment is a planned preventive inspection of the machinery industry. The means of inspection, in addition to the human senses, must also have certain inspection tools and instruments. It is carried out on a regular inspection card. Regular inspections of people and mechanical drafting software are called periodical inspections. Check. Accuracy checks should also be made on mechanical equipment to determine the degree of accuracy of the equipment.

Equipment maintenance should be carried out in accordance with the Qingdao Machinery Regulations. The equipment maintenance regulations are requirements and regulations for the daily maintenance of the equipment.

(1) The equipment must be neat, clean, sturdy, and lubricated. Construction machinery should be recruited for anti-corrosion, safety, etc. operation contents, operation methods, use of tools and materials, and standards for land use and precautions;

(2) daily sunshine machinery inspection and maintenance and regular inspection of the site, methods and standards;

(3) Inspection and evaluation of the contents and methods of the maintenance worker's level of maintenance equipment, glass machinery, etc.

Second, equipment, three-level maintenance system
The three-level maintenance system is the beginning of the mid-1960s in China. It summarizes the pre-repair system of the former Soviet Union's mechanical seal joint program based on the practice in China, and gradually perfects and develops a maintenance and repair system, which embodies China's equipment maintenance management. The center of gravity of the mechanical drawing software was changed from repairs to maintenance, reflecting the progress of China's equipment maintenance management and the clearer maintenance-management approach to prevention. The three-level maintenance system includes the following items: daily maintenance of equipment, primary maintenance and secondary maintenance. The three-level maintenance system is based on the principle that the operator is mainly responsible for the maintenance of the equipment, the warranty, and the compulsory maintenance system for the people's machinery. The three-level maintenance system is to rely on the masses, give full play to the enthusiasm of the masses, implement group management, special groups, and do a good job of equipment maintenance of agricultural machinery maintenance and effective methods.

(1) The daily maintenance and repair of the daily maintenance equipment at the equipment site, generally with daily maintenance and weekly mechanical processing and maintenance, also known as daily insurance and weekly warranty.

1. The daily insurance day insurance is carried out on-duty by the equipment operation workers, and the four things of the mechanical design and manufacturing before the class, the attention of the class and the four things after the class are seriously performed.

(1) Four things in the class to digest the pattern data and check the shift record. Wipe the machine factory preparation, according to the provisions of lubrication. Check whether the handle position and manual operation position are correct and flexible, and whether the safety device is reliable. Check if the transmission is running at a low speed. Check whether the mechanical forum is normal and whether the lubrication and cooling are smooth.

(2) During the class five pay attention to the operating sound, equipment temperature, pressure, liquid level, electro-hydraulic mechanical gas, hydraulic pressure, pneumatic system, instrument signals, safety insurance is normal.

(3) Four things after the class close the switch, all the handles put mechanical science and technology to zero. Remove iron scraps and dirt, clean the oil on the track surface and sliding surface of the equipment, and add oil. Clean the workplace, organize attachments and tools. Fill in the records of the Tianjin mechanical handover class and the record of the operating platform, and handle the transition procedures.

2. Zhou Baobao Zhou Baobao is operated by the equipment operator at the end of each week. The maintenance time is: General equipment 2h, fine, large, thin equipment 4h.

(1) Clean the equipment guide rails, chemical mechanical parts and exposed parts of the transmission, and clean the work site. To achieve cleanliness inside and outside no dead, no rust, the surrounding environment clean.

(2) Manipulate the transmission coal mine machinery to check the technical conditions of each site, tighten the loose parts and adjust the fit clearance. Check interlocks and safety devices. To achieve a normal drive sound, safe and reliable machinery industry press.

(3) Hydraulic lubrication oil line, dust felt, oil filter, oil added or oil change. Check the hydraulic system to achieve clear oil quality in Tianjin. The oil path is smooth, no leakage, and no injury.

(4) The electrical system wipes the surface of the motor and snake skin to check the insulation and grounding. The washing machine is complete, clean and reliable.

(2) Level 1 Maintenance Level 1 maintenance is mainly based on operators, with the assistance of maintenance workers, partial dismantling and inspection of equipment according to the mechanical drawing plan, cleaning of prescribed locations, dredging of oil roads, pipes, replacement or cleaning of oil lines, felts, etc. The oil filter is adjusted to fit the clearances of the equipments of each equipment company and fasten all parts of the equipment. The time for the first-level maintenance is 4-8h. After the completion of the first insurance, the records shall be made and the defects of the machinery manufacturing and automation not yet cleared shall be recorded. The workshop mechanic shall organize the acceptance. The scope of a land reservation shall be the full use of equipment by the company and strict implementation of key equipment. The main purpose of a land preservation is to reduce the wear of machinery and drawing equipment, eliminate hidden dangers, and prolong the service life of the equipment. This will provide guarantees for the production of equipment in order to complete production tasks during the next guarantee period. (C) Secondary Maintenance Secondary maintenance is mainly based on maintenance workers. Operators participate to complete the maintenance. The second-grade maintenance was included in the Taiyuan Railway Machinery School, which was repaired by the equipment. The equipment was partially dismantled and inspected and repaired. The wearing parts were replaced or repaired. The electric parts were cleaned, changed oil, checked and repaired, and the technical conditions of the equipment were fully met. The equipment meets the standard requirements. The secondary maintenance takes about 7 days.

After the completion of the second insurance, maintenance workers should fill in the details of the mechanical industry maintenance and inspection records, which shall be checked and accepted by the workshop mechanics and operators. The main goal of the two guarantees is to make the equipment reach a good standard, and mechanical excellence network to improve and consolidate the equipment in good condition and extend the overhaul cycle.

The implementation of the "three-level maintenance system" must enable operators to perform "three good" mechanical engineer examinations, "four meetings", "four requirements" and observe the "five disciplines" for equipment. The three-level maintenance system highlights the status of petroleum machinery in maintenance and repair of equipment and plans to more concreteize the requirements of “three good” and “four meetings” for operators, and improves the knowledge and skills of operators to maintain equipment. The three-level maintenance Shenyang Railway Machinery School system broke through the relevant provisions of the original Soviet plan for pre-repaired areas and improved some of the shortcomings in the planned pre-repair system. The implementation of the three-level maintenance system in the middle of the machinery and equipment plant also learned to absorb some of the practices of the management of weapons, and stressed the group management. The three-level maintenance system has achieved good results and experience in our country's enterprises. It has been implemented in three levels of maintenance system by mechanical drawing, which has effectively improved the availability of enterprise equipment, reduced the accident rate of equipment, and extended the period of equipment overhaul. Reduce coal mine machinery equipment repair costs, and achieved a good technical and economic results.

Third, the use of maintenance requirements for fine, large and thin equipment

(Glass machine 1) Four tasks (1) Scheduled personnel. According to the fixed-person system, operators of fine, large, and thin equipment should select those who have strong mechanical capabilities, high technical skills, and rich practical experience in this type of work, and should remain relatively stable for as long as possible.

(2) Set maintenance personnel. Metallurgical machinery companies with fine, large and dilute equipments can organize professional repair or repair groups for fine, large and thin equipment according to the company's conditions. They are specifically responsible for inspection, precision adjustment, and maintenance of thin equipment for fine, large, and mechanical watches. ,repair;

(3) Set operating procedures. The fine, large, and thin equipment shall be divided into type-by-set compiling machine processing plants to make procedures, display them and strictly enforce them;

(4) Set spare parts. According to the sources of food machinery and spare parts used in the production of various fine, large and thin equipment, the reserve quota is determined and given priority.

(B) Precise equipment use and maintenance requirements (1) The papermaking machinery must strictly follow the instructions to install the equipment;

(2) Equipment with special requirements for the environment (constant temperature, humidity, shock, dust) Enterprise machinery industry Press industry should take corresponding measures to ensure the accuracy of equipment:

(3) During routine maintenance, the equipment shall not be disassembled, and it is found that the machinery manufacturing and automation often stop immediately, and no sick operation is allowed;

(4) Strictly implement the cutting specifications specified in the equipment specification, and only allow the direct machining of parts into Xiamen Machinery Line. The machining allowance should be as small as possible. When machining castings, blank surfaces should be sandblasted or painted;

(5) In the non-working hours, the maid should add guards and stop for a long time. It should be regularly wiped, lubricated and air-operated.

(6) Attachments and special tools shall be provided with special cabinet racks for mechanical placement, kept clean, protected against injury, and not loaned.

Fourth, the use of power equipment maintenance requirements
The power equipment is a key equipment for the company to close Hangzhou, and it has high temperature, high pressure, flammable, toxic and other risk factors during operation. It is the key location for safe production, and it is necessary for the continuous and stable supply of safety for Suzhou Machinery. Kinetic energy, there are special requirements for the use and maintenance of power equipment:

(1) Operations operators must train Hangzhou Machinery in advance and pass the examination;

(2) Must have complete technical data, safe operation technical regulations and operating records;

(3 mechanical equipment) The operating personnel should perform the inspection at any time during the shift and must not leave the work at will.

(4) In case of abnormal mechanical drawing in the process of operation, the on-duty personnel shall urgently handle according to the operating procedures and report to the superior in a timely manner;

(5) Ensure that all kinds of indicator instruments and packaging machinery safety devices are sensitive and accurate, and check regularly. Backup equipment is complete and reliable;

(7) Conduct preventive tests and seasonal inspections on a regular basis;

(8) Safety education is often carried out on duty personnel's mechanical manufacturing and automation personnel, and the safety and security system is strictly enforced.

Fifth, equipment area maintenance

Equipment area maintenance is also called maintenance of mine mechanics package mechanism. Maintenance workers are responsible for the maintenance of equipment in certain production areas in the Mainland. They work together with production workers to perform routine maintenance, circuit inspections, maintenance of regular machine basic knowledge, planned repairs, and troubleshooting, and are responsible for completing equipment availability and failure rates in the pipeline area. And other assessment indicators. Regional Maintenance Responsibility The construction machinery parts are a good form of strengthening equipment maintenance for production services, mobilizing the enthusiasm of maintenance workers and enabling production workers to actively care about equipment maintenance and repair work. The main organizational form of professional maintenance of garden machinery equipment is the regional maintenance team. The regional maintenance team is fully responsible for the maintenance of the equipment in the production area and the mechanical design manual of the emergency repair engineers. The task of this task is:

(1) Responsible for the maintenance and repair of equipment in the region, and ensure that the completeness rate of the equipment, the Suzhou machinery rate for fault shutdown, and other indicators are completed;

(2) Seriously implement the equipment periodic inspection and regional tour inspection system to guide and supervise the operators to perform routine maintenance and regular maintenance of mechanical maintenance;

(3) Under the guidance of the workshop mechanics, participate in the survey of equipment conditions, accuracy inspections, adjustments, leaks, and failures to carry out the analysis and status monitoring of China Machinery Industry Federation.

The advantages of this type of equipment maintenance organization in the regional maintenance group are: a high degree of mobility in the construction of China's engineering machinery business network when the emergency repairs are completed, so that the equipment repair can be stopped in the shortest time, and the attendant can complete the tasks when they are not called. Preventive work and participation in planned repairs. The division of metallurgical machinery and equipment maintenance areas should take into account Liugong mechanical factors such as the distribution of production equipment, equipment conditions, technical complexity, production needs, and the technical level of repair and fitment site. The workshop equipment can be divided into several areas based on the above factors, and the area maintenance group can also be divided into equipment types. The equipment of the production line shall be dredging machinery to divide the maintenance area by lines.

The regional maintenance team shall prepare a periodic inspection and accuracy inspection plan, and stipulate that each class conducts routine inspections of the equipment on the time of mechanical science and technology. In order to ensure that these tasks do not affect production, planned inspections of equipment are scheduled to be carried out on non-working days in the factory, and routine inspections for each class are to be conducted during the lunch break of the mechanical science and technology production workers.

Sixth, improve the equipment maintenance level measures

In order to improve the maintenance level of the equipment, the hydraulic machinery of the maintenance worker should basically achieve the three standards, that is, standardization, process, and institutionalization.

The standardization is to make the maintenance content uniform, which parts should be cleaned, which lifting machine parts should be adjusted, and which devices should be checked. According to the situation of each enterprise, they should be considered and stipulated in accordance with objective laws.

Process technology is based on different equipment of plastics machinery to develop various maintenance procedures and maintenance according to regulations.

Institutionalization is based on the different working conditions of different equipment, stipulating that no mechanical watches have the same maintenance cycle and maintenance time, and strictly implement them.

For regular maintenance work, work-time quotas and material consumption quotas shall be established and assessment shall be conducted at a fixed amount of chemical machinery.

Equipment maintenance work should be combined with the production economic contract responsibility system for assessment. At the same time, enterprises should also mobilize the masses to carry out equipment maintenance work for specialized mechanical watch groups and carry out self-inspection, mutual inspection, and major equipment inspections.
