The wheel loader maintenance techniques
Public Group active 3 months, 1 week agoExcavation machine to perform on a regular basis to protect enjoying their goal is to reduce the machine failure, extending the life of machine application; reduce machine down time; the progress of the work force, a decrease of operating capital. Govern fuel, lubricating oil, water and air can be reduced by 70% of the fault. In fact, about 70% of failures are caused by poor governance.1, fuel managementSelection of different grades of diesel fuel depending on the ambient temperature; diesel fuel is not entering into the impurities, dirt and water, or fuel pump will prematurely wear; high paraffin and sulfur content in the low-quality fuel, the engine will occur against; daily operations After the fuel tank to fill the fuel, to prevent the tank inner wall of water droplets; daily operations to open the discharge valve of the fuel bottom water; Although the road in the air in the engine fuel exhaustion or replace the filter, to be ranked. Minimum ambient temperature of 0 ℃ -10 ℃ -20 ℃ -30 ℃ diesel grades 0 # -10 # -20 # -35 #.2, other oil managementOther oils containing the mobilization of oil, mini wheel loader, gear oil; different grades and different grades of oil can not mix and; different varieties to explore oil in the production process from the chemical action or physical effects of the additives; to ensure that clean oil, to prevent debris (water, dust, particles, etc.) entering into the oil label; selected based on ambient temperature and usefulness. Ambient temperature and viscosity of the oil should be used, the ambient temperature is low viscosity of the oil should be used; gear oil viscosity is relatively large, the spirits are sad ~ to adapt to the larger transmission load, hydraulic oil The viscosity is relatively small, in order to reduce the liquid flow resistance. Excavation machine oil in Table 2 Select the container outside temperature ℃ oil type replacement cycle h Change L to mobilize the machine sump -35-20 the CD SAE 5W-30 250 24 -20-10 the CD SAE 10W -20-40 the CD the SAE 10W -30 -15-50 the CD the SAE 15W-40 0-40 the CD the SAE 30 rotary mechanism box -20-40 the CD the SAE 30 1000 5.5 damper shell the CD SAE 30 6.8 hydraulic oil tank, the CD SAE 10W 5000 Model PC200 type: 239 PC220 type : 246 the CD the SAE 10W-30 CD SAE 15W-40 final drive the CD SAE90 1000 5.43, grease managementTake oil (butter) can reduce the active surface of the wear and tear, to prevent showing the noise. Grease storage custody can not be entering into the dust, sand, water and other impurities; elected choice of the lithium base grease G2-L1, anti-wear performance, practical overloaded conditions; filling, to try all the old oil extrusion and wipe clean to prevent the adhesion of the sand, I believe ~ tomorrow will be good.4, filter maintenancePlay the role of filter impurities in oil or diesel water pump, to prohibit intrusion within the system may cause a malfunction; various filters to be replaced on a regular basis in accordance with the request of the (operation and maintenance manual); replace the filter should be checked for metal attached on the old filter, such as the invention of the metal particles Woodland timely diagnosis and using the modified approach; application of pure filter in conformity with the provisions of the machine. Shoddy filter filter to poor surface of each one of the filter layer and the quality of the data does not meet the request, it would seriously affect the normal application of the machine.
