Make preparations before your job 1. Make a small job plan. 2. Debugging equipment. Inspect equipment state comprehensively, install and adjust according to agricultural technical requirements and technical requirements of the engine, such as the entire plant spacing of the regulators, and so on, and conduct field tests to exclude hidden dangers before the operation. 3. Check plots and roads. According to the conditions of soil quality, lyricism and ground temperature, determine the time and method of operation, rationalize the area, and reduce the turning of the ground. 4. Prepare enough oil and materials.
Reasonable use of agricultural machinery 1. Reasonable grouping, as much as possible in parallel operations of more than one farm tool. 2. Used properly. Minimize the number of tractors entering the ground, seize the locust operation, and strictly follow agricultural farming technical requirements to ensure the quality of operations. 3. Correct operation. The start, driving, parking, and flameout of the tractor, as well as the steering and shifting during driving, and the operations of braking and fuel supply are directly related to the fuel consumption. To keep the starting device in good condition, the long-term parking should be turned off in time. Select the appropriate gear and throttle operation. Take Dongfanghong 802 tractor as an example, the four-speed small throttle is about 20% less fuel than a large throttle. Keep the engine operating at normal water temperature and oil temperature. Experiments have proved that under the same conditions, the water consumption is 80°C to 90°C. The fuel consumption is increased by 3% to 4% when the water temperature is 60°C, and the fuel consumption is increased by 25% when the water temperature is 30°C. If the oil temperature is too high, the oil will deteriorate and deteriorate.
Maintaining the state of agricultural machinery and equipment is in good condition. The state of tractors and agricultural implements is closely related to the technical state and fuel consumption. Insufficient engine cylinder compression force, poor injector spray, incorrect fuel injection angle, air filter plugging, and poor lubrication all increase fuel consumption. For example, the injection angle is 3~4 degrees ahead of schedule, fuel consumption is increased by 1.5% to 2.0%, gears in clutches, gearboxes, central transmissions, and reducers of tractor transmissions, bearings are not properly mated, lubrication is poor, and transmission efficiency is high. As a result, a large amount of engine power is lost in the transmission and fuel consumption increases. The technical status of the walking device is not good, and it has a great impact on fuel consumption. If the tire pressure is 20% lower than the regulations, the fuel consumption will increase by about 10%. To reduce fuel consumption, it is necessary to ensure correct adjustment of the farm implement's traction line, smooth surface of working parts, and sharp edges. It is necessary to ensure that the implement drive is effective and reliable, with flexible rotation, good lubrication, and timely elimination of plugging. People often don't care if the tractor leaks oil, but this is a loophole that cannot be ignored.
Maintenance of agricultural machinery as required 1. Maintain air cleaner, diesel filter, oil filter. 2. Replace lubricants on schedule. Late change of oil changes the quality of the oil and increases the wear of the parts; premature oil change results in wasted oil. 3. Fill the oil level as required. The oil level in the sump is too high and the oil dripping into the combustion chamber can cause burning oil. Excessive oil levels in other locations will accelerate damage to the seal and cause leakage. The vent hole of the crankcase is kept clear to prevent oil leakage and contaminate the engine oil. 4. Reasonable use of cleaning oil. According to the degree of contamination of the parts, clean in sequential order. For example, first wash the diesel filter, then wash the air filter filter, and finally wash the oil filter. In the repair room, washing with the parts tank car wash can save cleaning oil.
Modification equipment 1. Diesel preheating. After the engine combustion system is technically modified, the diesel fuel is warmed through the exhaust pipe before entering the fuel pump, which can improve the atomization conditions and allow the diesel engine to fully burn. This will not only save fuel but also increase engine power. The modified tractor can save about 5% of fuel. 2. Modified oil filter. The wire oil filter is converted into a sawdust pulp filter, a cotton filter, and a toilet paper filter. The filter performance is improved and the oil use time can be extended. 3. Install a fuel-saving smoke reducer. If a large and medium-sized tractor consumes 5,000 kilograms of diesel per year, it can save 5% of fuel after installing a fuel-saving smoke reducer, and it can save 250 kilograms a year.
Doing a good job of oil purification oil purification is of great significance to reduce machine tool failure, reduce machine wear, improve the tractor's "three-rate", and extend the service life of the tractor. Oil purification should be: closed, filtered, sedimentation, cleaning, oil discharge and buffer unloading, float oil, metering and refueling. Conditional oil spots and more specialized farming teams and agricultural machinery specialists shall establish a fuel purification device to meet the qualified requirements for oil purification.
