The publication about need to carry out a running in of new cars, about the running in organization and also who and in what order should see off her. After a running in maintenance operations are carried out (on the TO-1 tractor), check and if necessary tighten the broken fastenings, draw up the statement on a running in.
In an economy the new equipment arrives. Often car or a tractor come to a heat of field works when in them especially big need, and it is clear to place aspiration them in operation as soon as possible.
Acceleration of input of new equipment in a system shouldn’t occur at the expense of quality of an operational running in of cars at all. Derogation from these rules recommended by plant, very often leads to undesirable consequences: to refusal of separate knots or units of cars, and sometimes and to breakages.
Owing to the wrong running in not only there are technical malfunctions, but also indicators of machine and tractor units worsen. Work of a new tractor with full loading without carrying out all volume of an operational running in if casually also won’t lead to appreciable damages, by all means will negatively affect work of separate knots and units, especially the engine and transmission (a dymleniye, a povyyoshenny consumption of the karterny oil, the lowered capacity, knocks and the noise, the increased heating of cases).
Need of a running in of new cars for an economy speaks that at machine building plants units and knots of the car run in empty, full extra earnings of the interfaced rubbing surfaces isn’t reached. The collected tractor too passes only short-term bench running in on all transfers without loading. The main objective of a factory running in – to estimate quality of assembly: lack of podtekaniye, zones of the increased heating, correctness of adjustments.
At the engine which has not passed a necessary running in, wear of details of piston group for the first 200 business hours approximately same, as at the worked 2000 hours of correctly rolled engine. The length of life of vtulochno-roller chains after a running in at the stand or on the combine raises for 10-12 percent.
Final extra earnings of rubbing surfaces of interfaces of knots and mechanisms of the new and capitally repaired cars surely it should be carried out to the period of an operational running in in farms as is a necessary component of system of maintenance of cars, it provides decrease in intensity of wear of rubbing surfaces of details, allows to increase term of their normal work.
In process a number of requirements, basic of which is required to observe extra earnings also: gradual increase of loads of earned extra surfaces and smooth increase in speed of their relative moving; an optimum mode of greasing and intensive cooling of earned extra surfaces; careful removal from them abrasive and metal particles; optimum duration extra earnings depending on degree of loading and speed of relative moving of surfaces of a friction.
The running in is recommended to be begun with the smallest vozmozhyony loadings and then to increase gradually, in process of smoothing of roughnesses.
Big requirements show to greasing, especially in initial period runnings in. Greasing should wash away well products of wear process and cool rubbing surfaces, to form a strong oil film on them and to possess good penetration. Taking into account the stated principles develop rules of a running in for separate cars which provide in factory instructions on assembly and operation. A duty of the machine operator – strictly to observe these rules.
Properly to organize a running in of the new or repaired equipment in an economy? To whom and in what order it to lead?
The running in of a new tractor includes three stages. The first – a running in of a dviyogatel within 0,25-0,5 hours idling (on the lowered and normal turns) and tractor hydrosystems (lift and lower the easy car). The second – a tractor running in idling: for 30-40 minutes on working transfers and for 10-15 minutes on transfers of a backing, transport, with a hodoumenshitel. General duration of the second stage no more than 5-6 hours. The third – a tractor running in under loading on useful works within 45-55 hours according to the obkatochny table recommended for this brand.
For the second day the run-in tractor gets into gear, however, at first it use usually on transportation in good road conditions. At the first stage of a running in under loading the tractors T-150 and T-150K within 12 hours aggregate with the trailer 2PTS-4, then 20 hours – with trailers 1PTS-9 or ZPTS-12. At the second stage it is possible to work at a boronovaniye with hitch SG-21 or with one cultivator KPS-4 and four harrows. At the third stage tractors load stsepy of two kulyyotivator, three grain seeders or disk hoeing plow LDG-10. The general duration of a running in under loading in this case 50 hours. In the middle of the second week from the moment of the running in beginning the tractor is ready to normal work.
After replacement or engine repair a tractor run in in the following order: 20 minutes the engine idle; 30 minutes a tractor move empty on various transfers; 10 hours a tractor work with a half loading.
Before a running in check completeness of the car, filling and greasing of knots and units, quality of fastenings, electric equipment, adjustments. In the course of a running in carefully watch operation of units, paying special attention to noise and podtekaniye, on overheats of cases, on indications of control devices, reveal and eliminate malfunctions. After a running in carry out maintenance operations (on the TO-1 tractor), check and if necessary podtyagivayut external fastenings, draw up the statement on a running in.
