<p>Now the use of excavators more and more common, construction, mining and other industries are inseparable from it. On the excavator to implement regular maintenance, can reduce the machine failure, reduce excavator maintenance costs, improve efficiency and economic benefits. Then the daily maintenance from which to proceed? In general, construction machinery maintenance mainly includes the following two aspects.</p>
<p>First, do the fuel, other oil and lubricants selection and management.</p> <p>Excavator working environment has changed, which means that the choice of fuel should also be changed, according to different environmental temperature selection of different grades, the quality of qualified fuel, so as to avoid low-grade paraffin and sulfur content of high damage to the engine; Keep clean and pollution-free, can not be mixed with impurities, lime and water, or else will make the fuel pump premature wear; open the fuel tank before the end of the daily operation of the water valve release water, fuel tank after the operation to fill the fuel tank to prevent water droplets generated. Other oil, including engine oil, hydraulic oil, gear oil. The choice of oil and storage of these oils with the different grades and different grades of oil can not be mixed; to ensure clean oil to prevent debris mixed; according to the ambient temperature and use of different labels of oil, high ambient temperature, viscosity should be used Large oil, low ambient temperature should be used relatively small viscosity of the oil; gear oil viscosity is relatively large to adapt to the larger transmission load; hydraulic oil viscosity is relatively small, in order to reduce the liquid flow resistance. Lubricant (butter) is the role of surface friction to reduce the surface, thereby reducing the wear and tear, to prevent noise. Grease should be kept clean, not other impurities, such as dust, sand, etc .; recommend the use of lithium-based grease G2-L1, the anti-wear can be good for heavy-duty situation; As far as possible all the old oil squeezed out and wipe clean, to prevent sand adhesion.</p>
<p>Second, do filter maintenance. The role of the filter is to filter the oil or air in the impurities, to prevent impurities caused by the intrusion of the internal system failure; the use of machinery in line with the provisions of pure filter; filter in accordance with the (operation and maintenance manual) requirements of regular replacement, replacement Check whether there is a metal attached to the old filter, if found to have metal particles, should be promptly diagnosed and take measures to improve.</p> |
