Technical status of the factors of agricultural motorcycle

, Leading to the clutch friction plate and friction plate brake shoe wear increases, transmission gear wear increased; the uneven road surface, so that the assembly, components, the impact load increases, increased leaf spring, frame and mechanical transmission parts fatigue and tire wear. 2. The temperature of the outside temperature is too high, the engine cooling becomes worse, resulting in engine overheating, so that the combustible mixture of gas into the engine to reduce, leading to power down; high-temperature viscosity of the oil decline, and increased oxidative deterioration of oil to speed up the operation wear parts; the temperature is too high may cause the brake have a The outside temperature is too low, the oil viscosity, flow variation, increases the friction of each part of moving parts, resulting in difficulty in starting. At the same time the outside temperature is too low, the brake fluid will appear layered or freeze, affecting braking performance. Therefore, the engine warm-up work is very important, it is not only easy to start, save fuel, more importantly, reduce cylinder wear. Third, fuel, lubricating oil properties of rational use of fuel, lubricating oil is to ensure the normal operation of locomotives and the extension of agricultural life of the necessary conditions. 1. Fuel properties of diesel engines used in agriculture is a high-speed locomotive diesel engines, used diesel light diesel oil. Evaluation of the quality indicators light diesel oil pour point, anti-violent resistance, viscosity,[link widoczny dla zalogowanych], fractions and so on. Domestic brand diesel engine is determined based on freezing point, the selected general requirements for diesel fuel pour point lower than the ambient temperature 5-10qc, if the improper selection of diesel, such as a high freezing point in winter Xuanyong diesel, diesel fuel flow to deteriorate, resulting in oil or oil fuel system is not difficult, it is difficult to start. Speaking from the nature of diesel, anti-violent means it is mainly the cetane number, cetane number is too low, if selected, will cause behind the fire combustion process of growth has started the work of rough and difficult winter; if selected cetane number is too high, so that incomplete combustion of diesel, exhaust black smoke, reduce engine power and increased diesel consumption. In addition, if the viscosity is too large or too small; or the composition of heavy and difficult due to the formation of distillate mixture,[link widoczny dla zalogowanych], which can cause incomplete combustion of diesel, coke increased,[link widoczny dla zalogowanych], accelerated cylinder wear, engine power decreased. At the same time corrosion and cleanliness of diesel have affected the wear of the moving parts. 2. Lubricating oil performance quality indicators mainly in the viscosity, such as oil and oxidation resistance. Directly affects the viscosity of liquid lubricants. If the oil viscosity is too high in winter, the current difficulties and bad parts lubrication, increasing the wear parts; summer if the oil viscosity is too low, causing low oil pressure lubrication system, resulting in insufficient lubrication of the parts can not form a reliable film, also increased the mechanical wear and tear. If the oil is good, the friction surface of the part is not in direct contact, can reduce the wear rate of parts; if there is oil in the water or mechanical impurities, so that oil deterioration, wear increased. Oil after long-term use and deterioration due to high temperature, if the continued use of easy to form a gelatinous sediment and carbon deposition, destruction of the metal parts heat and movement exercise capacity. Blocked by dirt road or even oil, tubing and the destruction of the lubrication system normal operation. Fourth,[link widoczny dla zalogowanych], agricultural mismanagement locomotives use of unreasonable and proved: the length of mechanical life depends not only on parts of the structure, operating conditions, fuel, lubricant performance and other objective factors, but also with the driver's reasonable use and maintenance has a lot of subjective factors, it is manifested in: 1. Load carrying capacity of the vehicle the size of the vehicle, load is reasonable, are a direct impact on agricultural motorcycle parts wear. If long-term overload, lead frame, leaf spring, transmission and tires are designed to withstand the load exceeds the limit, it must lead to early wear and tear parts. 2. Quality of the vehicle running after the car or locomotive repair factory was going through some adjustments, but the parts machined surface is quite rough, if after a reasonable period of transition and heavy-duty work immediately, it will increase the wear parts, reduce the machine's life. 3. Quality of maintenance of good quality maintenance to eliminate hidden dangers in time to ensure the normal operation of agricultural motorcycle. We should implement the 4. Pilot operation of machine operation method hand driving and driving skills, will be directly related to the parts of life, the driver driving in the long term to explore a set of operating practices, such as cold rolling slowly forward, preheat temperature,[link widoczny dla zalogowanych], light tread Slowly lift and low block start, maintain the temperature, moderate speed, time shift, slide right, correct and reasonable trailer and other reasonable methods of operation, it locomotives extend the service life of the farm to ensure road safety are useful.
