Excavator maintenance is necessary, but some wrong practices in maintenance will hurt the excavator more. Xiaowang summed up the following points today to see if he has been recruited, and if there is no change, he will be encouraged.

01

Fuel management

1. Different brands of diesel oil should be selected according to different ambient temperatures;

2. Diesel oil should not be mixed with impurities, dust and water, otherwise the fuel pump will be worn out prematurely;

3. The high content of paraffin and sulfur in inferior fuel oil will cause damage to the engine;

4. After the daily operation, the fuel tank should be filled with fuel to prevent water droplets on the inner wall of the fuel tank;

5. Open the drain valve at the bottom of the fuel tank to drain water before daily operation;

6. After the engine fuel is used up or the filter element is replaced, the air in the road must be exhausted.

02

Management of other oils

1. Other oils include engine oil, hydraulic oil, gear oil, etc.;

2. Oils of different grades and grades cannot be mixed;

3. Different types of excavator oil have different chemical or physical additives in the production process;

4. It is necessary to ensure that the oil is clean and prevent the mixing of sundries (water, dust, particles, etc.).

03

Grease Management

1. The use of lubricating oil (butter) can reduce the wear of the moving surface and prevent noise;

2. When the grease is stored, it should not be mixed with dust, sand, water and other impurities;

3. When filling, try to squeeze out all the old oil and wipe it clean to prevent sand from sticking.

04

Maintenance of the filter element

1. The filter element plays the role of filtering impurities in the oil circuit or gas circuit, preventing it from invading the system and causing failure;

2. Various filter elements should be replaced regularly according to the requirements of the (Operation and Maintenance Manual);

3. When replacing the filter element, check whether there is metal attached to the old filter element. If metal particles are found, diagnose and take improvement measures in time;

4. Use pure filter elements that meet the requirements of the machine. The filtration capacity of the fake filter element is poor, and its filter layer and material quality do not meet the requirements, which will seriously affect the normal use of the machine.

05

Maintenance in the rainy season

In the rainy season, the parking position of the excavator is particularly important.

If conditions permit, you can park the excavator in the garage, and try to avoid parking in an excessively humid environment. When choosing indoor storage, anti-rust operation is very important. In the case of long-term parking, the equipment should be started and driven once a month to charge the battery.

If the conditions do not allow, when you need to park the excavator outdoors, first observe and judge that the surrounding geographical environment is safe, away from rivers or hillsides that may cause landslides; it is not a good parking lot under the big trees, thunderstorms The weather is easy to be struck by lightning, and if the tree is blown down on the excavator in the windy weather, it will also cause huge losses.

Choose a place with a solid road for parking. It is best to park on cement or asphalt. Generally, there are few cement roads in the places where excavators work, and most of them are in the field. In this case, long-term parking should be selected at On firm ground, try to avoid parking on rough ground.

HW-17

1. Flexible and high work efficiency;

2. Equipped with bulldozers, it can level the ground and backfill the earth, and increase the stability of the whole machine;

3. The fuselage is small and can be operated in a narrow field, the operation is simple and the operation is quick;

4. Quickly replace accessories, with the functions of digging, crushing, ditch cleaning and drilling, and the utilization efficiency of the machine is greatly improved.
