CPD CAR
Planned maintenance system maintenance and repair cars The reliability and operation of the vehicle in the pre- the Affairs of the established operating parameters can be provide baked under strict supervision of units and assemblies and the Prov- the progress of scheduled repairs. In industry and transport there are three system we planned repairs: • planning paleobotany; • planning-forced (standard); • scheduled preventive. Planning paleobotany repair is a PE- periodic, pre-scheduled, inspection equipment tion, during which the set data comprising- of components, assemblies, defined the scope and subsequent the performance of repair work. This is the most cost-effective system and, Naya, however, with a long downtime in repairs- those. Acceptable for agricultural machinery (flounder- new, etc.), working certain times of the year (season service). Planned-forced (standard) repair pre- sees a planned stop of the machine for repairs, when individual nodes, regardless of their physical state States, replaced or restored. This repair guarantees high reliability, but has high forge cost. The system finds application in the repair aircraft and equipment, the reliability of which depends on people's lives. In repair shops of motor vehicles operates system outage, which is cetait combines the advantages of both the above systems the. It provides high reliability car after repairs at the lowest labor and material minimal cost and simple machines. The system of preventative maintenance (CPD) is called a set of strictly scheduled in time IU- measures for the care, supervision and repair of motor vehicles, - aimed at accident prevention and the maintenance of mA- tire in a state of constant operational readiness. System outage extends not only to vehicles but and utility equipment, and buildings, with- structures, other communications, vehicles enterprises. CPD activities are preventive in nature and executed according to plan, in advance prepared on the basis of- research Institute approved standards and specifications exp- lately. The system includes: • content and purpose should be implemented preventive measures throughout the term machine service; • content, purpose and frequency of maintenance works; • standards for manufactured repair work. Depending on the purpose, content, size, and PE- ridionale system preventative maintenance it is proposed that two types of repair: current and capital. Repairs — planned complex of works on maintenance of the replacement of parts or assemblies to ensure the normal Noah car work within the established working settings until the next scheduled maintenance. Frequency and timing of this repair due to approved schedule, according to which the cars OS- travliata for repair. During the current repair disassemble only individual ing parts of the vehicle, with a meticulous inspection of the determi- share their status and by small repairs restore nalivayut its performance. In addition, evaluate the nature and intensity of wear, which is very important for the mouth- tion timing and scale of major repairs. In the period between routine maintenance about the car- slazhivaetsya attached persons (driver, repair mechanic), specialist training and are responsible for compliance with all conditions operation and care for him. Overhaul maintenance consists in yourself: • compliance of the operating modes, according to a passport- the data entirely; • maintain vehicle in good working condition the Institute by conducting various types of technical- services — IT, IT-1, IT-2, one HUNDRED, etc.; • production of small repair (elimination of leaky- opportunities, tightening glands, etc.). Daily maintenance is performed with preparing your car for work, use it for shift. IT is aimed at ensuring safety of movement tion, neat appearance, fueling, Mac scrap and coolant. The first and second maintenance-1, to-2 run through some runs that are installed depending on the type, brand of car and EC- operation. Seasonal maintenance (SRT) performs- Xia to prepare transport for the autumn-winter and spring- not years of operation. One HUNDRED combined with TS-1 or TS-2 and carried out twice a year. Maintenance and technical repairs performed are complemented with a repair service of motor transport enterprises and service stations. Overhaul — the largest PLANO- vy repair in which the car is subjected to disassembly for detailed clarification of his condition. Designed for restoration of cars and components run to the next overhaul (or write off), accounting for at least 80% of normal mileage for a new vehicle biles. The direction of vehicles for major repair Pro- performed according to valid technical status tion and the preset operating time between repairs. Trucks come for an overhaul if the frame and cab (body passenger car, and bus stations- sa) and at least three other major units in Liu- BOM combination require major repairs. Aggregates- further on overhaul, if their basic DETA- whether in need of repair, and if their performance is not can be repaired at the current repair. Norms of mileage before overhaul for various car models are set in the technical conditions of the conditions for the first category of conditions and a penny- General climatic zones. For example, VOLVO mileage (minimum) before capital overhaul is 300 000 km the same sizes well run are the basic units of these vehicles — DWI- gatel, gear shift, front and back mos you steering. For other conditions the rate of mileage to major re- Monta is corrected using the coefficients for the WTO- Roy category it equal to 0.8, for the third — 0,6 from these for the first category. Overhaul is accomplished in the basics- nom in specialized repair shops. On the repair companies applied two methods of re- Monta vehicles — individual and aggregate. When an individual method of repair of the car and its units dismantled, removed items and restore again establish after repair on the same car or Ah- regattas, the disadvantage is that the vehicle length more time in the shop waiting refurbished rooms with- based parts, components. The advantages of the method relative includes ability to save mates of detail is not required designed to repair, so the quality of the repair over high than when aggregate method. Aggregation is a method of repair where the worn parts are replaced with new or pre- repaired. The method reduces the residence time of AB- tomobile to be repaired, but the successful use of it can to be provided with careful adherence to the principle of com- imagemanagement. Aggregate method of repair is essential for re- montyh enterprises. It gives you the ability to create shifts- Fund spare parts and specialization of production in some works, for example the site of repair transmission, etc. |
