1. Thermal insulation devices should be added when assembling the engine. When working with tractors in winter, in order to enable the engine to start normally, a certain temperature of the lubricant should be maintained first, and additional installation of insulation devices should be considered. In the case of a battery capacity (a battery can be reconfigured), make a resistance heater that can be installed around the engine without interfering with the normal operation and disassembly of other components. The hot water heating circulation system can maintain the surface temperature of the shell at a constant temperature of about 15cc, which can effectively maintain the operating temperature of the engine itself and shorten the preparation time for starting the vehicle.
2. Reasonably select the viscosity of the oil. (1) The diesel in the diesel tank is discharged, and the diesel tank and the diesel filter are cleaned with diesel, and then the winter diesel is filled. The specification of refueling should be appropriately selected according to the temperature. When the temperature is 0 to 10°C, 10# light diesel oil is used; when the temperature is -10 to -20°C, 20# light diesel oil is used; and when the temperature is -20 to -35°C, 35# light diesel oil is used. If there is no diesel with the corresponding grade, an appropriate amount of anti-coagulant can also be added to diesel. (2) Release the engine oil in the oil sump, clean the lubrication system with a 4:1 or 5:1 mixture of diesel oil and engine oil, and then fill the HC No. 11 or HC No. 8 winter oil, and The switch of the oil filter is adjusted to the working position in winter, and the fuel pump, governor and hydraulic oil tank are also to be replaced with HC No. 11 or HC No. 8 oil. (3) Release the gear oil in the gearbox, differential, and steering gear, add HC-20 winter gear oil after cleaning with diesel oil.
3. The cooling water in the cooling system is discharged, and the washing liquid is cleaned and cooled with clean water, caustic soda and kerosene in a ratio of 10:0.75:0.5. When adding cooling water without antifreeze, always pay attention to the reading on the engine water temperature table. If the engine idles idle, malfunctions or stops for a long time, the cooling water temperature in the water tank will gradually drop, such as when the water temperature drops At 50 to 60°C, the cooling water should be released and the crankshaft should be cranked to drain the cooling water. When it is found that the radiator is frozen, it is necessary to wrap the frozen place with cotton yarn or waste cotton cloth, and then water the hot water. When pouring hot water, start from the lowest point of the radiator.
4. The electrolyte in the battery is made of concentrated sulfuric acid and distilled water. The greater the concentration of concentrated sulfuric acid in the electrolyte, the greater its relative density (concentration). The lower the freezing point, the more difficult it is to freeze. When the temperature is low, the electrolyte tends to freeze. Therefore, in the case of low temperature, the outer surface of the battery In addition to covering insulation such as felt and batting, the density of the electrolyte must also be increased. The density of the electrolyte is 1.25 to 1.27 in summer and 1.28 to 1.30 in winter. The electrolyte level is less than 10 to 15 mn above the shield. Diluted sulfuric acid with a density of 1.05 should be added instead of distilled water as in summer.
5. Tractors must take care of and prevent malfunctions in the winter. First of all, when cooling the vehicle at low temperatures, the water in the cooling system should be added. The water temperature should be higher than 80°C. At the same time, the preheating work should be done well before starting the car. Then the car must be started again. It is forbidden to start the car after adding water and force the traction to start. This is Work to be done before starting the car. In addition should also do the following:
(1) The locomotive is stored in the open air in winter. Before starting, charcoal is used to bake the bottom shell of the oil tank. It should also be checked while the oil is being roasted to observe the state of the oil until the oil is thinned by thickening. At the same time, special attention should be paid to the fact that under no circumstances should an open-fire grill be used to prevent accidents such as mechanical damage and oil fire.
(2) When adding hot water, the water temperature should be in the range of 80-90%. When adding, the cooling system should be slowly added from the mouth of the tank. At the same time, the discharge valve of the body should be opened, and the cooling water should be released while heating the water. The purpose of this is to: First, we must ensure that the water added to the cooling system has a certain temperature, so that it is between 80 to 90%; Second, the slow addition of water and water, will not make the water tank parts due to sudden heat There is a burst phenomenon. When discharging water, it should be done by hand while putting water on the side, until the released water feels hot (the water temperature table indicates that the reading is more than 40%), then close the water discharge valve, fill the water tank and pull up the insulation curtain, and pay attention to any In any case, do not add boiling water when the engine is too cold.
In addition, the conditional unit electricity can be steam warmed up to increase the tank temperature.
6. After the engine has just started, you must not bang the throttle, because the lubricating oil inside the body is thicker and the lubrication effect is poor. In addition, the spring at the plunger, injector, valve, etc. is in a low-temperature operation state, and is damaged due to cold brittleness. The accident occurred.
7. The pressure of the tires used in tractors should be maintained at a certain level of pressure, which should generally be higher than in summer (the upper limit of the range). Ensure that the tire has some friction with the ground.
8. The following aspects should also be noted in winter operations:
(1) After starting the car, it should be idling for 3 to 5 minutes, but it must not exceed 10 minutes, because the internal parts of the engine, gears, etc. are not well lubricated at the start, resulting in increased wear. When starting, slow-speed gears should be used to allow the body and the drive system to be fully lubricated and then gradually replaced by high-speed gears.
(2) If it is difficult to start a heavy load on an ice-snow road, some sand, slag, etc. may be laid on the lower part of the drive wheel to increase the adhesion to prevent slipping. Driving on an icy road should slow down, try to avoid overtaking, do not use an emergency brake when braking, and use intermittent slow braking to prevent the locomotive from slipping and damage the locomotive parts due to too much braking force. In addition, on the ice and snow roads must also carry vehicles with snow chains, triangle wood and other items. Install tire chains on the tires to be symmetrical, and remove them immediately after the passage of ice and snow.
(3) When passing through a frozen river, you should first understand the thickness of the ice layer and the direction of the hail. Only when it is safe to do so can it be accessed.
(4) The dangerous road beside the mountain should be stopped when the snow is frozen.
(5) In the early spring and late autumn, due to the harder soil freezing, it is easy to make a part of the locomotive to generate a large vibration, so the vehicle speed should not be too fast so as to avoid damage to the parts.
The above describes the problems that tractors should pay attention to during winter use, and also the issues that should be paid attention to during the key season when the locomotive life span is high. Such as the machine can achieve the above points in the winter can effectively improve the service life of the locomotive itself. .
In tractor maintenance, the most common method is to replace new parts. It can be proved that some parts do not have to be replaced because of structural permission. The worn parts of the parts can be turned in one direction; or the location can be repaired by changing the position. This method is easy to operate and repairs. Rapid, low cost, can guarantee the service life and performance of the locomotive.
