The technical status of the tractor has been significantly improved after commissioning. The average power before commissioning was 7.35 kilowatts, the average fuel consumption was 340 grams per kilowatt-hour, the average power after commissioning was 8.16 kilowatts, and the average fuel consumption was 299.2 grams per kilowatt-hour. The total power was restored 3588. Kilowatts, average fuel savings 120 kg/year. Lubricant timely replacement technology Meaning: Regular inspection and analysis of agricultural machinery oil quality, according to oil change standards, timely oil change, to ensure a good lubrication of agricultural machinery. At the same time, monitoring the changes in the state of agricultural machinery technology, determine the maintenance strategy of agricultural machinery. The main technical contents include: Lubricant physical and chemical performance indicators (viscosity, acid value, moisture, impurities, water-soluble acid and alkali) detection technology, oil change standards and change the oil cycle to determine the lubrication system related to the analysis of the working status of the system . Effect: The replacement of farm machinery lubricating oil usually uses a fixed oil change cycle. The use of regular inspection and analysis of timely replacement technology can avoid replacement of lubricants with good quality when they are replaced in a fixed cycle, reduce oil change, save resources, and reduce waste oil pollution. It can also be found that the quality of lubricants is not improved when the replacement time is not reached. Problems, to avoid poor lubrication conditions, increased wear, serious mechanical failure. Water-based cleaning technology Meaning: Using water as cleaning medium, using water-based cleaning agent instead of organic solvent, combined with different cleaning methods, a new environmental protection cleaning technology that quickly and efficiently removes parts of dirt. Water-based cleaners are made by adding a small amount of surfactants, detergents, corrosion inhibitors, solubilizers, defoamers, foam stabilizers, and other chemical substances in water to replace flammable dangerous petroleum solvents. Part of the surface of oil stains, stains and other mold stains. The main technical contents include: selection and preparation of water-based cleaning agents, application of cleaning methods such as high pressure cleaning and ultrasonic cleaning. Effect: According to test statistics, using 1 kg of water-based cleaning agent can replace 20 kg of organic solvent, the cost is only 10-20% of organic solvent. Water-based cleaning agent can not only dissolve and remove all kinds of water-soluble dirt. In addition, non-water soluble dirt such as synthetic resin and fat can be removed. Diesel exhaust pollutant reduction technology Meaning: The technology of purifying the exhaust gas is based on the in-house purification measures and fuel reformation of the diesel exhaust.
