In order to carry out automobile maintenance work better, improve work efficiency and maintenance quality, the following principles should be followed in automobile maintenance work.
1. Taking the reliability of automobile as the center, carrying out the principle of prevention, compulsory maintenance and repair as appropriate
In the work of automobile maintenance, we should carry out the maintenance guiding ideology of ' prevention, regular testing, compulsory maintenance, repair as appropriate ', strengthen regular testing and maintenance work, and reduce repair work.
2. Strengthen technical inspection, reasonable arrangement of maintenance projects, timing and operation depth The regular testing of automobiles through modern means is an important means to inspect and identify the technical status and maintenance quality of automobiles, and it is an important guarantee to promote the development of maintenance technology and realize the repair of visual conditions. The test and diagnosis of the car should be able to be carried out without disintegration, and the location and cause of the fault or hidden trouble should be identified. The main contents of the detection and diagnosis include: the main performance affecting the safety of the car, assembly and equipment (braking performance, handling stability and sideslip, steering performance, front and rear lighting, seat belts, airbags, etc.), the vehicle in particular the reliability of the engine and fault signals and causes (noise, wear, deformation, cracks, etc.), power (car
Speed, acceleration performance, chassis output power, engine power, torque), economy (fuel consumption) and noise and exhaust emissions. According to the results of automobile testing, the spirit of ' compulsory maintenance, as appropriate repair ' principle, the car maintenance content and operation depth of timely and reasonable arrangements, to eliminate repair instead of maintenance, unnecessary disassembly and other practices, reduce ineffective disassembly operations, improve maintenance quality, avoid unnecessary waste.
As a result of the upgrading of domestic cars and a large number of advanced performance of imported models, in order to make maintenance work more accurate, reasonable, maintenance work should be carried out by the implementation of manufacturers recommended content.
3. Adopt new technology, new process, ensure maintenance quality, improve maintenance speed The maintenance quality directly affects the technical condition and service life of the automobile. Therefore, in the maintenance work must establish the point of view of quality first, strictly abide by the process procedures, strengthen the quality inspection, so that the maintenance of the car to meet the requirements of technical specifications. Maintenance work should also ensure the quality of the premise, improve the efficiency of maintenance operations, as far as possible to shorten the parking maintenance time, in order to improve the efficiency of the use of the car, adapt to the transport work (or car owners) requirements.
Therefore, automobile maintenance work should actively adopt advanced technology and equipment, improve the maintenance process, improve the operation methods. With the rapid development of modern automobile manufacturing technology, the reliability of automobiles is getting higher, because of the new technology, the use of new materials, the workload of car maintenance is gradually reduced, car trouble-free mileage and overhaul interval greatly extended. As a result, many cars are already able to use scrap miles under normal use, without the need for an entire vehicle overhaul. Mastering the knowledge of automobile reliability has important guiding significance for automobile maintenance work.
The reliability of the car is divided into inherent reliability and reliability of use.
1. Inherent reliability Inherent reliability refers to the intrinsic quality that a car is given when it is designed and manufactured. Once the car is out of the factory, this inherent reliability has been determined, which reflects the intrinsic nature of the car. For us, we can only make full use of and maintain its inherent reliability, and in general it cannot be improved by means of maintenance, but only through redesign or modification. For example, ordinary engines compared with high-quality engines, there are high failure rates, short service life, poor economy and other defects. We can only reduce failures to some extent through maintenance, not improve their overall performance and longevity.
If replaced with a high-quality engine, a longer service life and a lower failure rate can be obtained (but the replacement of the engine is a retrofit behavior).
2. Reliability of Use The reliability of the use of cars (also known as job reliability) is the quality shown in the use of automobiles. The use of reliability can be maintained and raised by means of maintenance and 卨. In the course of using a car, the purpose of its maintenance is to maintain its inherent reliability and improve the reliability of its use. Therefore, the vehicle maintenance weight in the control of the decline in the reliability of various factors.
In automobile maintenance, we should do a good job in the statistical work of all kinds of data, regularly test cars, timely maintenance of cars on demand, quantitatively check the effectiveness and economic benefits of car maintenance, reduce blind unnecessary maintenance operations. Three basic principles for car repair, you know?
