What is difficult for excavators to dig steel plates? Teach you four ways

[BONOVO]

▊ Oil, hydraulic oil, gear oil precautions

1, under harsh conditions (high temperature, high pressure), the oil used by the engine and the working device will deteriorate, therefore, even if the oil is not dirty, the new oil should be replaced at the specified time as required.

2, oil is equivalent to the blood in the human body, we must be careful when using, to prevent debris (such as water, metal particles, dust, etc.) into it, the failure of the excavatorin the operation, most of them are caused by impurities mixed in the oil.

3. It is strictly prohibited to mix different brands and grades of oil.

4, should be in accordance with the amount of refueling, refueling too much and too little will produce adverse phenomena.

5, when changing the oil, be sure to replace the corresponding oil filter at the same time.

▊ Coolant precautions

1, the river contains a lot of calcium and other debris, so if the machine uses the river water, the scale will adhere to the inner wall of the engine and radiator, which will lead to poor heat exchange and overheating.

2. The engine radiator of the new machine is equipped with the original antifreeze filled by the excavatormanufacturer, which can effectively prevent the cooling system from being corroded and can be used continuously for two years or 4000 hours; Therefore, it can be used even in areas with hot weather.

3, antifreeze is flammable, be sure to pay attention to fireworks.

4, the proportion of antifreeze and water should be determined according to the ambient temperature.

5. The coolant should be added after the engine cools.

6, if the coolant level is low, it will overheat the engine, and the air in the coolant will corrode the cooling system.

▊ oil filter maintenance

1, the oil filter is a very important component, it can prevent impurities from entering the important device in the oil circuit and gas circuit, so as to reduce the occurrence of failure, the oil filter should be replaced regularly according to the requirements; When the excavator is used under harsh conditions, the replacement cycle should be shortened according to the quality of the diesel oil (sulfur content) used.

2, do not clean the oil filter (cylindrical) and use again, should be replaced with a new oil filter.

▊ Precautions for wearing parts

Wear parts should also be replaced regularly; Due to the low pressure return oil hose, high pressure hose, rubber water pipe and other key safety parts, will age, wear, deterioration, deformation, resulting in oil, water leakage, fire or major accidents, which is very dangerous.

In SUMMARY:

For the excavator maintenance time and the replacement of wearing parts, it must not be settled or delayed, because it is difficult for us to judge the degree of quality deterioration of these parts through a simple inspection, so no matter what their status is, they should be replaced regularly!
