Komatsu excavator summer maintenance, you sure you understand?

Summer is here, hot and hot, for the driver, for the Komatsu excavator spare parts, is a test, the temperature is high, the excavator often produces a variety of faults due to high temperature during the operation, if the excavator driver in the excavator work Pay attention to the following points, it can effectively reduce the occurrence of excavator failure.

Excavator summer maintenance tips 1: cooling anti-gas resistance

The summer temperature is high, the excavator hydraulic spare parts are high temperature, the heat dissipation is difficult, and the driving air resistance is easy to appear, so that the engine sometimes stops for a few minutes and it is difficult to start. Once the gambling resistance is generated, the excavator spare parts should immediately stop and cool down to eliminate the malfunction.

Excavator summer maintenance tips 2: Watch the water temperature gauge at any time to prevent water shortage

High-temperature weather driving, always pay attention to check the amount of cooling water, pay attention to the water temperature gauge. When the invention is short of water, immediately start the idling and cool down, then add water, and be careful not to open the radiator cover immediately to prevent burns.

Excavator summer maintenance tips 3: oil anti-deterioration

Lubricating oil is susceptible to heat thinning, resulting in poor oxidation resistance, deterioration, and even failures such as burning the shaft. Therefore, the hydraulic spare parts and the final drive should be replaced with summer lubricating oil, and the number of lubricating oil and oil quality should be checked frequently, and the original parts should be replaced in time.

Excavator summer maintenance tips 4: timely cleaning engine oil stains

If the external oil of the engine is too thick, it will affect the heat dissipation, and it will cause hidden troubles for various components. The high-pressure injection method can be used to clean the engine parts with the cleaning agent that does not corrode the body parts.

Digging machine summer maintenance tips 5: to prevent the water tank water temperature is too high

In summer, the cooling water of the excavator evaporates and is fast, and it is necessary to add sufficient cooling water before exiting the vehicle, and often check the water level during work. For single-cylinder diesel engines with waterless thermometers, always pay attention to the red standard height of the water tank floats. If the floats are not properly applied, they should be repaired in time. If there is a boiling phenomenon in the work, do not directly add cooling water. The work should be finished, the generator should be decelerated, and the cooling water should be added slowly after the water temperature drops, so as to avoid cracks in the water tank when it encounters cold.

Excavator summer maintenance tips 6: to ensure the best fuel supply time

In summer, the oil supply time of the excavator should be adjusted. If the oil supply is too early, the engine will make a knocking sound, and sometimes it will show a reversal phenomenon; the oil supply time should not be too late, otherwise the engine will work weakly.

Excavator summer maintenance tips 7: use high viscosity lubricant

The viscosity of the lubricating oil can improve the performance of the lubricating oil and increase the sealing performance. When changing the lubricating oil of the excavator, thoroughly clean the oil filter, the filter, and the oil pan. The diesel engine equipped with the transfer switch should be turned to the "summer" position in the summer, so that the oil can be cooled into the main oil passage to avoid the viscosity of the lubricating oil.

Excavator summer maintenance tips eight: accurate application of batteries

In the summer, the electrolyte in the excavator battery should be sucked out a part, and the appropriate amount of distilled water should be taken to control the specific gravity of the electrolyte to about 1.25. The liquid level should be checked every 5-10 days, and distilled water should be added when it is insufficient. The battery should always maintain sufficient power. When the excavator does not work for a long time, the battery should be removed and placed in a ventilated, dry room, and charged every 15-20 days. In addition, keep the outside of the battery clean.

In summer, the weather is hot. On the one hand, the driver's physical exertion is high and it is easy to fatigue. On the other hand, the whole machine is prone to failure due to high temperature, so both should be adjusted in time to replace the excavator spare parts in time to achieve their best condition. Spend the summer safely.
