Some common failures of the mucking rock loader during construction operations, such as: the excavator's walking deviation, the reason may be the damage of the walking distribution oil seal (also known as the center rotary joint oil seal); the flow of the two hydraulic pumps is not the same; the side walking motor something wrong. If the hydraulic cylinder is drained quickly, the safety relief valve may not be tightly closed, or the oil seal of the cylinder may be severely damaged.
Daily maintenance of mucking rock loader In order to prevent the failure of the excavator, it is necessary to pay great attention to the maintenance of mucking rock loader during daily use.
The maintenance of the mucking rock loader includes checking, cleaning or replacing the air filter element; cleaning the inside of the cooling system; checking and tightening the track shoe bolts; checking and adjusting the track back tension; checking the air intake heater; replacing the bucket teeth; adjusting the bucket clearance; checking Front window cleaning liquid level; check and adjust air conditioner; clean cab floor; replace crusher filter (optional). When cleaning the inside of the cooling system, after the engine is sufficiently cooled, slowly loosen the water injection port cover to release the internal pressure of the water tank, and then discharge the water; do not perform the cleaning work while the mucking rock loader engine is working. The high-speed rotating fan will cause danger; when cleaning When changing the coolant, park the machine on a level surface.
At the same time, before starting the mucking rock loader engine, you need to check the liquid level of the coolant (water); check the engine oil level, add oil; check the fuel oil level (fuel); check the hydraulic oil level (add hydraulic oil); Check whether the air filter is blocked; check the wires; check whether the horn is normal; check the lubrication of the bucket; check the water and sediment in the oil-water separator.
Modern mucking rock loader adopts electro-mechanical liquidization control mode. There are many failures encountered by mucking rock loader in daily work, and in order to reduce the occurrence of failures, it is very important for daily maintenance of the excavator. Only by guaranteeing the double guarantee of maintenance and maintenance, can the mucking rock loader work better.
