A, clean the excavator internal impurities

Mechanical impurities generally refers to nonmetal material such as dust, soil and engineering machinery in use process produce some of the scrap metal, wear debris, etc. These impurities for komatsu excavator is huge, not only make out relative motion block, speed up the process of wear parts, and will cooperate surface scratch, destroy the lubricating oil film, make the parts temperature, lubricating oil deterioration. And in selecting excavator parts may not choose accessories in the process of using authentic wear are likely to cause excavator damage, as well as the produce of the impurities, in the selection of lubricating oil or accessories must choose normal brand, repair is to regular repair shop, ensure the excavator work smoothly

Second, pay attention to the anti-corrosion excavator

Park, the process of rainwater, the chemicals in the air by mechanical parts into the machinery, such as foreign channels, crack corrosion mechanical parts inside, accelerate the mechanical wear, increase the mechanical failure. Due to the corrosion effect is sometimes invisible, scratching, easy panties neglected, thus its harmfulness is bigger. In use, management and operating personnel should according to the local weather conditions, the air pollution situation, take effective measures to reduce the chemical corrosion effect on the mechanical, the key is to prevent the rain and the invasion of the chemical composition of mechanical in the air.

Third, the influence of the temperature of excavator

At work, each component has its own normal range of temperature.

1, to prevent overload operation under low temperature, ensure the effective operation of the low speed estimate temperature stage, make the mechanical requirements on temperature and then to travel or work, don't cry because it is the problem and not ignore the important role;

2, to prevent mechanical operation at high temperature, mechanical operation process to check all kinds of thermometer, found the problem immediately stop check to find fault in a timely manner to eliminate. For want of reason, absolutely can't treated and still make the mechanical work, although he is ill. In the usual work, pay attention to check the working condition of the cooling system. For water-cooled machine, daily work must be checked before, add cooling water; For air-cooled machinery, also want to regular cleaning the dust on the air cooling system, guarantee the cooling air duct flow.
