Ensuring the reliability of agricultural machinery

Abstract

Today, there is a decrease in the production of domestic agricultural machinery, the aging of the rolling stock of agricultural enterprises is taking place. In these conditions, special attention is paid to the problem of effective use of technology. The issue of improving the quality of manufactured domestic agricultural machinery and ensuring its reliability both at the stage of production and manufacture and during operation is becoming more and more urgent. Demands are constantly growing both to improve the reliability and productivity of agricultural machinery, and to increase the range of work performed.

The authors noted that the operability of agricultural machinery is ensured by the organization of the maintenance system and the performance of maintenance and repair. Timely diagnostics and preventive maintenance can reduce operating costs and increase both the reliability of the machine and tractor fleet and its technical characteristics.

The reliability of agricultural machinery at the design and manufacturing stage will depend on the correctness of calculations and provision of parameters (implementation of DSTU) and quality assurance of technology and production (regulations, assembly, testing), and at the operation stage – on proper maintenance in a working condition (quality of maintenance and current repairs) and ensuring operability and durability (qualification of operators, intensity of operation, seasonality, etc.).

It is emphasized that in order to improve the reliability and efficiency of the use of agricultural machinery, it is important to timely carry out a set of control and diagnostics operations at the sites of its operation. A flow chart for organizing maintenance and routine repairs was proposed, which is based on the principle of reliability management with the participation of a diagnostic service. Timely comprehensive diagnostics of all systems and assemblies allows you to identify malfunctions and eliminate them, preventing a decrease in performance. Filling in the diagnostic card based on the history of diagnostics allows you to determine the need to perform certain works during maintenance.
