The difference between factory repair and factory repair of trains, what does railway freight car se

Both factory and section repairs of trains are ways of maintaining and repairing trains, but they differ in scope and scale of work.

1.Definition of plant repair and section repair:

Factory repair: When the train (including passenger cars and wagons) runs for a period of time, it needs to be overhauled on a large scale, and this repair generally needs to send the vehicle back to the manufacturer for processing, so it is called factory repair.

Section repair: In the daily maintenance of the train, a small-scale overhaul is required, and this repair is usually carried out in the depot, so it is called section repair.

2.The difference between factory repair and section repair:

Scope and scale of work: Compared with section repair, factory repair has a wider scope of work and a larger scale. In order to ensure that the train can run safely and efficiently, the vehicle needs to be thoroughly inspected, repaired and tested.

Whereas, section repair is mainly to carry out daily maintenance and simple repairs to maintain the normal operation of the vehicle.

Location: Factory repairs usually need to be carried out at the manufacturer, because the manufacturer has more comprehensive and professional maintenance equipment and knowledge, and is able to carry out in-depth maintenance and testing. Whereas, section repairs are usually carried out at depots or stations, as these places have basic maintenance equipment and tools.

Frequency: The frequency of factory repairs is usually low, and it may only need to be carried out every few years depending on the vehicle's condition and maintenance requirements. On the other hand, it is more frequent and may need to be done once a month or every few months.

In general, plant repairs and section repairs are important maintenance methods to ensure the safe and efficient operation of trains, but they differ in scope, scale, location and frequency of work. In practice, according to the operation condition and maintenance needs of the train, there will be corresponding maintenance plans and arrangements.

Trains (including passenger cars and wagons) need to be overhauled after a period of operation, and this small-scale overhaul is usually done in depots.

It can be repaired, and this kind of repair is called Duan repair. However, after a few minor repairs (i.e., section repairs), major repairs are required, and in the case of major repairs, they are usually returned to the manufacturing plant for repairs, which is called factory repairs.

Factory repair is a comprehensive inspection and thorough repair of the vehicle, and the necessary modern technical transformation. The purpose is to restore the basic technical performance of the Obikei vehicle and bring it close to the level of the new vehicle after repair. The technical quality of the main components should be able to ensure the normal operation during the repair period.

Factory repairs are generally carried out in vehicle repair shops, and if necessary, in conditional depots.

Carry out. Section repair is a comprehensive inspection of the vehicle, weighing and focusing on analysis. Focus on the decomposition and inspection of the vehicle's driving command, coupling buffer device and braking device and other components.

Eliminate hidden dangers of failure, repair damaged and worn parts; Replace parts with excessive wear and tear according to regulations to prevent the expansion of failures. The purpose is to maintain the basic performance of the vehicle, prolong the service life of the vehicle, and ensure the safe operation of the vehicle. The technical quality of the main components should be able to ensure a period of repair.

Section repairs are carried out in the depot.

To explain simply, minor repairs and major repairs, section repairs are minor repairs, and factory repairs are major repairs.

Railway wagon section repair regulations.

1 1 Railway wagons are an important means of transport to complete the task of railway freight, especially in the national operation, except for the locomotive car and some tank cars and special cars, there is generally no fixed maintenance unit, and the number is large, the type is many, therefore, it is necessary to strengthen the regular maintenance of the wagon. In order to unify the technical requirements and quality standards for maintenance, this "Railway Wagon Section Repair Regulations" is specially formulated.

1 2 The maintenance system of railway wagons in China adopts the principle of prevention, which is divided into regular maintenance and operation maintenance. The fundamental task of truck section repair is: to keep the truck's performance in good condition before the next factory repair; Extend the service life of vehicle accessories; Reduce temporary repair, eliminate driving accidents, ensure operation safety, and improve vehicle efficiency.

1 3 In order to improve the quality of the repair of large trucks, we must adhere to the principle of quality first and conscientiously implement the repair procedures. Each bureau shall prepare the process specification, and each section shall prepare the technical operation process and process card. In the maintenance work, the repair operation plan should be strengthened, the scope of spare parts exchange should be expanded, and the mechanization of repair should be actively adopted to achieve the purpose of balanced production, improved quality and improved repair efficiency.

Factory repair is to carry out a full imitation of the vehicle inspection and thorough repair, and carry out the necessary modern technical transformation. The purpose is to restore the basic technical performance of the vehicle and bring it close to the level of a new vehicle after repair. The technical quality of the main components should be able to ensure the normal operation during the repair period.

Factory repairs are generally carried out in vehicle repair shops, and can be carried out in conditional depots if necessary.
