Maintenance and overhaul management of chemical plant equipment

Maintenance and overhaul management of chemical plant equipment

The implementation of the production of the link, production equipment is indispensable. The continuity of chemical enterprises is very large, also has high temperature, high pressure and other characteristics. If there are certain problems with the equipment in the chemical workshop, it will lead to many consequences, which will bring adverse effects to the production, and in serious cases will cause the problem of casualties. Therefore, for chemical enterprises, need to do a good job of maintenance and overhaul of various equipment, so as to lead the development of chemical enterprises.

A, the importance of maintenance of chemical plant equipment overhaul

(a) can make the chemical plant equipment to extend the service life

Equipment in the chemical plant plays an important role, the number of times the staff work on maintenance and overhaul of equipment is extremely frequent, the danger is also relatively large, the technical performance is very high, the whole work process is tedious, the repair work has real-time. The staff need not only professional skills, but also qualifications in the maintenance of chemical plant equipment. Enterprises need to hire professional personnel to maintain and overhaul the equipment, so that not only can the wear and tear of chemical workshop equipment effectively reduce, but also make the application of chemical workshop equipment to improve the life.

(2) Provide corresponding guarantee for the operation and management of chemical enterprises

The equipment in the chemical plant must be well maintained and inspected, which is very important for the operation of chemical enterprises. The link between the production equipment and the inlet pipe is effective, with materials entering at one end and exiting at the other. The process of transferring the original material places great demands on the chemical plant equipment. If there are problems with the equipment, this can lead to problems with the quality of the product. Only by maintaining and overhauling the equipment in the chemical plant can the materials and the quality of the products in the chemical enterprise be implemented and the operation of the chemical enterprise be made fully operational.

(iii) Improving the safety of production and operation

For chemical enterprises, safety in operation is very important, if there are some small problems in the equipment, it will have a huge impact on the later production and operation, there are hidden dangers in safety. For example, if a pipeline is cracked and leaks oil or gas, it can easily cause an explosion, threatening the lives of staff and property. Maintenance and overhaul of chemical plant equipment can make the operation of chemical enterprises safer.

Second, the maintenance and overhaul of chemical plant equipment strategy

(a) Touring inspection efforts to enhance the safety of equipment operation

In the process of installing chemical equipment, it is necessary to increase the touring inspection so that the equipment can operate safely. Under general conditions, there are three main types of roving inspection in form. Firstly, operators go on tour to carry out inspections. Secondly, the maintenance and repair personnel in the area carry out the inspection tour. Thirdly, the touring inspection is carried out by the technical staff on site. The use of these three types of roving inspection efforts can make the equipment safe operation.

(ii) Improve the management model to improve maintenance levels

With the rapid changes in science and technology, chemical plant equipment is gradually moving into reform and towards automation. The traditional management mode can no longer meet the requirements of the chemical plant equipment management. Therefore, the traditional management model needs to be constantly reformed, and in the reform to achieve innovation, so that the level of chemical plant equipment management can step up to a new level. The means of maintenance and overhaul taken in chemical companies need to be modernised and rationalised, with problems in operation identified in the first instance and reasonable measures taken in response to specific problems.

The use of modern management techniques to prevent problems before they occur allows the chemical plant to operate more smoothly. Firstly, in order for equipment not to be replaced blindly, the right equipment needs to be chosen to give full play to the benefits of the equipment and avoid causing waste to the business. Second, regular training of staff on the operating procedures of the equipment, so that staff can master the use of equipment. Third, strengthen the inspection and management of equipment, timely discovery of hidden dangers of accidents in equipment, advance notice of changes in equipment performance, reduce the probability of sudden failure of equipment, ensure that the equipment is in good running condition and reduce the cost of maintenance.

(C) the implementation of maintenance work, so that the operation can be safe

The inspection process is easy to have various differences, so the way to take maintenance varies. There are two main forms of overhaul, the first is to do a good job of temporary overhaul. Secondly, to do a good job of shutting down the production overhaul. For specific overhaul work, it can be classified into major, medium and minor overhaul. The shutdown overhaul is generally carried out after the equipment has been operating for a period of time, and if the operation of the system is completely stopped, then the maintenance of the equipment is carried out. When implementing a major overhaul session, both the quality of the equipment and the intensity of the overhaul can leave operating conditions severely inhibited. Therefore, it is necessary to choose a reasonable overhaul method for different types of systems or different cycles, and you can choose some minor or medium repair methods to reduce the number of equipment repairs and avoid causing greater losses to the operation of the enterprise.

(4) Do daily maintenance on equipment to prevent safety accidents from occurring

In the process of maintaining and overhauling the equipment in the chemical workshop, it is necessary to do a good job of maintenance measures so that the operation of the equipment can be in a safe and stable state and play the role of prevention before it happens. When carrying out inspection tours, it is necessary to carry out comprehensive verification work and to reinforce loose parts of the equipment in time, using special tools to tighten them. Let the equipment will not exist in terms of security hidden dangers, to eliminate the occurrence of security failures.

(E) remove harmful media, do a good job of chemical equipment maintenance

Chemical equipment pipelines are interconnected, the medium has a strong liquidity, and has a certain high temperature, with flammable and explosive characteristics.

For some of the larger equipment, the maintenance process requires the implementation of high-altitude operations. From these characteristics, it can be concluded that the process of overhauling chemical equipment needs to comply with the safety requirements. In the process of overhauling the equipment, the equipment needs to be stopped and the media needs to be removed, including: temperature, pressure, flow, etc. These media have flammable and explosive characteristics, and some media are toxic and can threaten the health of the overhauler.

For these harmful media need to do a good job of blowing out the replacement, and the implementation of the removal and disinfection, so that the maintenance of equipment can start from the inside, safe to carry out maintenance. When working at height, safety belts need to be fastened and permits for working at height need to be obtained. For internal maintenance of explosive media, obtain a maintenance certificate. In the process of overhauling system equipment in production, it is necessary to separate it from the system to prevent the effective spraying of media from the equipment pipelines, which can cause various unsafe accidents.

(vi) make good repair decisions and implement safe overhaul of chemical equipment

The actual condition of the equipment to do the corresponding decision-making, the process of maintenance of chemical equipment, there is not only major repair, there is also a medium repair, there are also minor repair aspects of the content.

When carrying out daily overhauls, work tickets are used to provide operating instructions, targets are set for the quality of the overhaul, a system of various certificates of conformity is set up for maintenance, and three certificates of conformity are required for quality control, so that the next step can be taken.

The subsystem does not exist alone, but is effectively linked to the various aspects of the overhaul and the inspection process has a certain validity. After the previous processes have been completed, the later processes can be perfected and controlled using process control.

The operating conditions of the equipment are mastered in depth, and the conditions occurring in the equipment are mastered in depth to understand some of the laws that exist in equipment failure, and a reasonable time is chosen to implement effective repairs to the equipment so that the repairs are more scientific and require a large amount of money to be invested.

Inspection work should be carried out sooner rather than later, people have a deep understanding of the state of the law of accidents, the need to implement the corresponding decision on the repair of chemical enterprises chemical enterprises need to implement a reasonable decision, regular inspection of equipment to do a good job, the formation of an important mode of condition testing. Ensure that the equipment can run safely, improve the life of the equipment, to create greater value for chemical enterprises, and promote the long-term stable development of chemical enterprises.

Third, concluding remarks

In summary, the process of maintenance of chemical workshop equipment needs to increase management efforts, so that chemical workshop equipment can run safely. Therefore, it is necessary to take reasonable protective measures to do the corresponding maintenance and overhaul of the equipment in the chemical workshop, to ensure that the equipment in the process of safe operation, to create higher economic profits for chemical enterprises.
