Method for calculating the maintenance cycle of tractors

Doing a good job of calculating the maintenance cycle of the tractor is a good habit for the tractor itself. Let's take a look at the specific methods:
1. Measured according to the hours of work completed by the tractor, that is, after a certain cumulative working hours of the tractor is completed, technical maintenance of a certain number is required. For example, Dongfenghong-75 tractors will perform shift maintenance every 10-12 operating hours; 50-60 operating hours, No. 1 maintenance; 240-250 operating hours, No. 2 maintenance - this measurement method will be implemented earliest It is also the basis of other measurement methods. The advantage is that it is easy to measure and it is easy to implement. The disadvantage is that the tractor carries out different work items with different load changes and different degrees of tediousness, but the technical maintenance cycle is the same.
Second, according to the workload of the tractor to complete the measurement, that is, each tractor to complete a certain amount of work (standard acres), to carry out a number of technical maintenance. This measurement method needs to calculate the standard MU workload based on the coefficient of conversion. The advantage is that the heavy workload is taken into consideration. The disadvantage is often that the maintenance factor and maintenance level do not meet the actual requirements of mechanical wear because the conversion factor is not accurate enough.
Third, according to the main fuel consumption measurement, that is, after each tractor consumes a certain amount of main fuel, it is necessary to carry out a number of technical maintenance. This measurement method is to multiply the first hour maintenance cycle by the tractor average hourly fuel consumption, and then correct it based on a large number of statistical data. Because the work done by the engine and the main fuel consumption are the same, so this measurement method is more scientific, it is more reasonable than the first two methods, can more fully reflect the tractor's working hours, load levels, wear levels and needs Maintenance situation. Of course, this measurement method also has imperfections. If the fuel system is not working properly, it will cause an increase in fuel consumption, which in turn leads to early maintenance of other parts.
Technical maintenance of agricultural machinery is carried out according to each work shift and certain period. The technical maintenance cycle measurement method is accurate and affects the quality of maintenance. If the technical maintenance period is not measured properly, the number of maintenances will be too much or too little, resulting in waste of maintenance materials, time, and unnecessary disassembly. Scientifically measuring the technical maintenance cycle and timely performing technical maintenance can reduce losses and prevent accidents.
