Seven points to know about loader repair knowledge
The loader repairs the weather in winter is harsh and cruel. Regarding the loader that can create wealth for us-it is undoubtedly a test. It seems that it is necessary to understand the certain loader repair knowledge. Some precautions for operation and maintenance are communicated with the broad drivers and friends, so that the wheel loader can serve you better.
1. Some drivers and friends do not understand the common sense of wheel loader repair, and it is relatively difficult to use the vehicle in winter. Here it is recommended that each start should not exceed 8 seconds. If it cannot be started, you should loosen the switch and wait for 1 minute before parking. Launched twice. After the engine is started, idle for a period of time (not too long, too long will form carbon deposits on the inner wall of the cylinder, showing the phenomenon of pulling the cylinder), one will charge the battery, the other will make the water temperature reach 55 ℃ and the barometer reaches 0.4Mpa, then Start again

2. After understanding the certain common knowledge of wheel loader repairs, you will find that: the general temperature is below 5 ℃, the water or steam should be preheated before the engine is started, and the preheated to 30 ~ 40 ℃ before starting ( The temperature of the first preheating cylinder, and then the temperature of the atomized diesel, because the general diesel engine is compression ignition);
3. Only when the water temperature of the diesel engine is higher than 55 ° C and the oil temperature is higher than 45 ° C are you allowed to perform full-load operation; the engine temperature and oil temperature should not exceed 95 ° C, and the torque converter oil temperature should not exceed 110 ℃;
4. When the temperature is lower than 0 ℃, the cooling water in the water tank, engine, oil cooler and torque converter oil cooler should be discharged after the operation every day to avoid frost cracking; there is water vapor in the air reservoir, which is often discharged, Avoid freezing, causing brake failure. If antifreeze has been added, it may not be released.
5. If the storage vehicle stops operating for more than half a month, it is necessary to start the engine once every 15 days and work for a period of time to charge the battery. If the time is too long, please remove the battery and use the charger to charge it The same is true for the vehicles to be sold), move together properly, and change the pressure parts of the tires to avoid tire deformation; the vehicles need to be parked for more than two months, it is necessary to disconnect or remove the battery negative electrode;
6. The usage of fuel oil, lubricating oil coolant and auxiliary materials used in diesel engines are as follows:
6.1 The diesel of the diesel engine is selected to be -10 # light diesel oil, and the fuel oil is -35 # light diesel oil in the cold area;
6.2 The engine oil of the diesel engine is selected to be CD grade. (For other oils and their amounts, please refer to the Degong product operation protection manual and the "Diesel Engine Operation and Maintenance Manual").
7. When the temperature is lower than 0 ℃, the concentration of antifreeze should be checked on time, and the use of untreated water as the engine coolant should be stopped together.
