High concentrations of fuel oil and lube oil in winter, poor fluidity, icing of cooling water and freezing of snow on the road surface, make it difficult for the tractor to start, lubricate and travel. Therefore, in addition to the prescribed technical maintenance and driving operations, the following technical requirements must be strictly observed.
Before the winter, all parts of the tractor shall be descaled, cleaned, adjusted and lubricated, and the technical status of the engine shall be comprehensively inspected. Valve clearances, injection pressures, etc. that do not meet the requirements must be adjusted to the specified range. In particular, the oil supply time must not be too late. It is easy to cause starting difficulties when it is too late. A comprehensive inspection and adjustment of the clutches, brakes, and operating mechanisms is also needed to prevent accidents in the snow and frozen roads.
Replace fuel and lubricants with winter oil. It should be replaced with diesel that has a freezing point below the local temperature of 5 to 10 degrees Celsius. When refueling, it must be strictly filtered. The oil in the oil pan should be replaced with No. 8 oil, the gear oil in the gearbox and the rear axle should be replaced with No. 20 gear oil. It is strictly forbidden that the lubricant in the governor casing exceeds the specified oil level to prevent the speed of the vehicle from being caused.
Adjust the proportion of battery electrolyte. The specific gravity of the electrolyte was adjusted from 1.25 to 1.26 for summer use to 1.28 to 1.29. In the high-cold area, it can be adjusted to 1.30 to 1.31. It is necessary to conduct a comprehensive inspection and maintenance of the electric starting system.
Heat the water to warm the body before starting the engine. Use the method of heating water while putting water on the side until the body drain valve flows out of warm water. Close the drain valve and use the crank to turn the crankshaft for dozens of turns so that all parts are full of oil and lubricated. It is forbidden to bake the engine with an open flame and start without cooling water. After the engine is started, it is necessary to extend the warm-up time and add insulation curtains in front of the radiator to ensure that the operating water temperature reaches 80 degrees Celsius or more. Long-term work at low temperatures is not allowed.
After parking at night, when the water temperature drops to 50 degrees Celsius, open the drain valve, put a net cooling water, and use a crank to crank the crankshaft several times until no water flows out. Do not close the drain switch. Some of the pilots were able to save time by leaving the locomotive open after the water switch was turned on, often resulting in an accident that caused the body to clog and the cooling water was not released, causing the body to freeze. There are also parking stalls that put water, causing the engine to cool and the body burst.
Strictly abide by the use of operating procedures. Prepare skid chains, triangle mats and other anti-skid tools before leaving the car. When you are on a frosty road, drive slowly. When going uphill, use a gear that can go up to avoid shifting halfway. When there is snow, you must pay attention to the edge of the curb.
The infrared thermometer is designed for measuring the human body forehead temperature reference. It is very simple and convenient to use. Accurate temperature measurement in 1 second, no laser spot, avoid potential damage to eyes, no need to touch human skin, avoid cross infection, one-click temperature measurement, and check for flu. It is suitable for home users, hotels, libraries, large enterprises and institutions, and can also be used in hospitals, schools, customs, airports and other comprehensive places, and can also be provided to medical personnel for use in clinics.
The normal body temperature of the human body averages between 36 ~ 37 ℃), exceeding 37.1 ℃ means fever, 37.3_38 ℃ is low fever, and 38.1_40 ℃ is high fever. Life above 40 ° C is always dangerous.
1. Human body temperature measurement: accurate measurement of human body temperature, replacing traditional mercury thermometers. Women who want to have a child can use an infrared thermometer (frontal temperature gun) to monitor the basal body temperature at any time, record the body temperature during ovulation, and choose the right time to conceive, and can also measure the temperature to judge pregnancy.
Of course, the most important thing is to observe whether your body temperature is abnormal at any time, to avoid flu infection, and to prevent swine flu.
2. Skin temperature measurement: To measure the surface temperature of the human skin, for example, it can be used for amputation and re-implantation surgery.
3. Object temperature measurement: To measure the surface temperature of an object, for example, it can be used to measure the temperature of the surface of a tea cup.
4. Liquid temperature measurement: measure the temperature of the liquid, such as the temperature of the baby's bath water. When the baby takes a bath, measure the water temperature, and no longer worry about being cold or hot; you can also measure the water temperature of the milk bottle to facilitate the preparation of Baby's milk powder
5. Room temperature can be measured:
※Precautions:
1. Please read the instructions carefully before the measurement, and the forehead should be kept dry, and the hair should not cover the forehead (please carry out the measurement in the environment of 10 ℃ -40 ℃) to ensure the accuracy of the measurement.
2. The forehead temperature quickly measured by this product is for reference only, and should not be used as a basis for medical judgment. If you find abnormal body temperature, please use a medical thermometer for further measurement.
3. Please protect the sensing lens and clean it in time. If the change of the ambient temperature is too large, you need to place the measuring instrument in the environment to be measured for 20 minutes, wait for it to adapt to the ambient temperature, and then use it to measure more accurate values.
