subject: Note excavator maintenance [print this page] There are many mines where there are excavators at work. Rocks more, this time to pay attention to the excavator chassis watch for loose, damaged. Check the track of the degree of tension than the tension in the ground level when some better song. Working in the mountains, the excavator working device will be faster the damage, pay attention to use of the excavator enhanced and timely replacement. Winter construction in north China will use excavators, excavators at this time to note the following maintenance issues, the first high-quality oil resistant to cold type of fuel, oil label attention, preferably twenty-negative or negative on the 10th No oil. Then, the excavator used to add antifreeze to the cooling water, or water tanks will freeze. Once again, the battery should be charged and discharged more frequently to prevent freezing of the electrolyte. Finally, to remove mud excavator chassis to prevent the excavator was frozen in the mud. The entire maintenance process, but also be very complicated.
Other oils, including engine oil, hydraulic oil, gear oil; different grades and different grades of oil can not mix and; different varieties of excavator oil added in the production process from the chemical or physical effects of different additives; to ensure oil clean to prevent debris (water, dust, particles, etc.) mixed; according to the environmental temperature and the use of selected oil label. Environmental temperatures are high, the oil viscosity should be used, the low temperature viscosity of the oil should be used; gear oil viscosity is relatively large to accommodate the large transmission load, hydraulic oil viscosity is relatively small, to reduce the liquid flow resistance.
Use of oil (butter) can reduce the wear surface movement to prevent noise. Grease storage custody, not mixed with dust, sand, water and other impurities; recommended use lithium grease g2-l. Anti-wear performance, and apply heavy working conditions; filling, you should try out all the old oil and clean to prevent sand adhesion. more excavator information, http://www.infoexcavator.com/construction-machinery/
