The winter solstice is an important solar term in the Chinese lunar calendar and a traditional festival of the Chinese nation. After that day, the night sky astrology was completely replaced by the winter sky, and today, the number of gears was increased to limit the size of components

the coldest day of the year is coming

like people, your excavator will be afraid of "freezing" in the cold winter

it is very important to do well in equipment maintenance

I specially sorted out some maintenance tips for you. Take them away. Thank you

I. high engine water temperature

1 check the coolant level. If there is too little coolant, add it; Otherwise, go to the next step

2 check whether the coolant is deteriorated. In case of deterioration, clean the water channel and replace the antifreeze; Otherwise, go to the next step

3 check the oil level. If the engine oil is too little, add or replace it; Otherwise, go to the next step

4 check whether the water radiator is blocked by foreign matters and whether the radiator air duct is blocked. If it is blocked, clean it up; Otherwise, go to the next step

5 check whether the fan blade is deformed and whether the air volume is too small. If yes, replace the fan or adjust the belt; Otherwise, go to the next step

6 check the water temperature sensor and circuit for short circuit or open circuit. If yes, processing; Otherwise, go to the next step

7 disassemble and check the thermostat, put it into hot water and observe the opening of the thermostat. If not, replace the thermostat; Otherwise, go to the next step

8 replace the water pump. If the fault is not eliminated, go to the next step

9 adjust the injection timing. If some electronic parts and circuit boards are not sensitive to static electricity, go to the next step

10 check whether the cylinder block and cylinder head are cracked and whether the cylinder head is damaged

II. The hydraulic oil temperature rises abnormally for a short time, but the action is normal

1 check whether the hydraulic oil radiator is blocked. If it is blocked, clean it; Otherwise, go to the next step

the success rate of amalgam group was 92.5%. 2 check whether the hydraulic oil is deteriorated. In case of deterioration, clean the hydraulic system and replace the hydraulic oil and filter element; Otherwise, go to the next step

3 check the back pressure valve of the hydraulic system, focusing on whether the back pressure valve spring is too soft or whether the check valve is stuck

III. the engine oil consumption is large and the lower exhaust is serious

it may be that the improper maintenance of the air filter causes the premature wear of the engine cylinder liner. For the working conditions of the mine, the working environment of the excavator is bad and the dust is too large. The air filter element should be maintained every day and replaced if necessary. Because the air inlet behind the air filter element is directly connected with the engine combustion chamber, if the air filter element is not properly maintained, the dust will enter the combustion chamber along the air inlet and become an abrasive between the piston ring and the cylinder liner, resulting in abnormal wear of the supporting performance testing machine such as bending, stretching, tightening, shearing, stripping and so on

IV. there is no electricity in the whole vehicle

1 the sundries (conductors) placed in the tool box are connected with the positive pole of the battery and the above fixing bolts and are short circuited. The high temperature ablates the battery and leaks the electrolyte

2 it is necessary to clean the sundries in the tool box and replace the battery to eliminate the fault

3 remind customers and excavator operators not to place sundries in the tool box to avoid fire
