FEATURES OF DEVELOPMENT OF LUBRICANTS FOR TECHNICAL MAINTENANCE OF TRACTORS
It is known that the lubricant filling operation maintenance of tractors represent more than 50 % of the total volume of maintenance work. From timely and quality of their implementation largely depends on the reliability and efficiency of machinery. Besides, when performing these operations in the field practically there is always an ecological danger caused by a possibility of hit of fuel lubricants to the soil. However many questions concerning technology and means of carrying out lubricant and filling operations in field conditions, are still insufficiently studied today. The analysis of references allows to draw a conclusion that historically, from the beginning of formation of the system and so far, improvement of lubricant and filling means, is carried out in the direction of resource-saving, and without ecological safety of their application in the field. Means for performance of lubricant and filling operations as the probes which are built in, for example, for control of level of oil in a case of the internal combustion engine, and portable (funnels filling and drain, wrenches for unscrewing of traffic jams of drain openings, canisters and pallets for discharge and collecting the fulfilled oils, etc.) and also mobile (maintenance units) on a design and operational properties for the specified time period significantly haven't changed. It predetermines need of their improvement as in the direction of resource-saving, and ecological safety. The received results can be used further at decision-making on improvement of technology and means of performance of lubricant and filling operations at technical tinning of cars in field conditions and also at statement of research problems of process of service of cars in the directions of resource-saving and ecological safety.
