First, all kinds of agricultural machinery should be in accordance with the requirements of the use of manuals, clean, lubrication, adjustment, fastening and other items before use to ensure that equipment in a good technical state to put into operation.
Second, the maintenance of the lubricating system of power machinery (such as tractors, diesel engines), in addition to the use of lubricating oil in accordance with the required standards, but also strictly abide by the lubrication system maintenance cycle and specifications, regular cleaning of the lubrication system, regular replacement of filter parts to reduce the machine Wear.
Third, the temperature in early spring is unstable and volatile, and the correct use of power machinery cooling systems cannot be ignored:
(1) to continue to do a good job of anti-freezing work, when the temperature is below zero at night, if no antifreeze is used, cooling water should be released to avoid freezing and cracking the body;
(2) When the machine starts at a low temperature, warm-up start shall be implemented;
(3) Pay attention to the normal operating temperature of the engine. When the water temperature reaches 40°C or above, it can only be operated with no load; 60°C or more can start the load operation; the normal working temperature should be kept between 80-95°C to reduce the engine's No unnecessary wear.
4. When the tractor is performing rotary tillage, sowing, irrigation and other operations, it must strictly abide by the operating procedures to ensure safe production.
The first is the net fuel economy. At present, most of the agricultural machinery engines are diesel engines. Therefore, the diesel purification work is very important. There are three ways to purify diesel fuel. First, the purchased diesel is left to settle for more than 96 hours, and then the hopper is added to the filter and a layer of silk cloth is added. When taking oil from the oil drum, the filter is wrapped with a layer of silk cloth or typewriter wax paper, and it should be cleaned or replaced regularly. In particular, the imported equipment of the farmland should be precipitated with diesel for 96 hours, filtered in three stages, and floated with oil. The oil should be filled at one night in the operating head to prevent water vapor condensation.
The second is the net lubricating oil. Always pay attention to the use of clean lubricants that meet the standards of this machine. The filter element of the oil filter should be regularly cleaned. The rotor-type filter should be affixed with a layer of suitable kraft paper of a wide and narrow length to facilitate the adsorption of dirt under centrifugal action. The dirt that is adsorbed on the filter element is best cleaned with an air pump and blows air from inside to outside, scrubs with a brush, and never wipe it by hand. Lubricant should be used as required. Do not casually inject other lubricants.
The third is net air. When the engine is running, each cylinder inhales 2-4 cubic meters of air per minute. In order to ensure that the air entering the cylinder is clean, the air filter must be inspected and cleaned regularly.
Fourth, the cooling water net, the engine cooling system is open type, cooling water is best to use soft water, that is, snow, rain or treated tap water and clean well water, cooling system cleaning ratio according to the volume of water plus 1% Caustic soda and 0.5% kerosene.
Fifth, there is a net of implements, and agricultural machinery operations are mostly conducted in the open air and in the open air. They often come in contact with dust, silt, and water. The body is most likely to be dirty. Therefore, it is necessary to scrub frequently, so that the body will not rust, if necessary, to make up the paint to prevent corrosion.
