Loaders are very important machinery in engineering construction. We will inevitably make some mistakes during operation. The following are some of the most common incorrect operations.
When the loader engine is just started, the body temperature is low, the oil viscosity is high, and the fluidity is poor. The oil cannot flow smoothly to all lubrication units in a short period of time. If you slam the accelerator at this time, the engine speed will instantly increase, which will easily cause instantaneous dry friction on the components, leading to severe wear and tear. The running resistance will also increase. If the accelerator is hit hard, the piston, connecting rod, and crankshaft will have violent impact, accelerating the damage of the parts. Therefore, after the loader is started, it should run smoothly and at low speed.
When the loader is operating, many drivers are accustomed to shifting gears while driving at high speed to perform shoveling work. Using the inertia of driving to rush towards the material pile will cause the whole machine to be violently impacted, causing uneven stress on each component, which will be harmful to the entire machine body. great. This will deform the bucket, boom, front frame, etc. Due to the sudden force on the transmission and clutch, the torque increases, the friction plates are easily distorted and deformed, and the transmission components are also easily damaged. The correct operation is that the loader puts the transmission lever in low gear before shoveling, drives towards the material head-on at speed II, slowly inserts the material at speed I, and gradually increases the throttle for shoveling.
Directly adding cooling water when the diesel engine is at high temperature will produce a large temperature difference, causing the tractor body to become brittle or cracked, which may lead to oil or air leakage. The correct approach should be to wait for the water temperature to drop, turn off the flame, discharge the water vapor, and then slowly inject cooling water.
If the loader is shut down immediately after heavy load operation, the cooling system will stop working and the heat dissipation capacity will drop sharply. The large amount of heat generated by work cannot be dissipated in time, causing the cooling water of the cylinder head, cylinder liner, cylinder block and other heated parts to boil, causing the parts to overheat and ablate at high temperatures. Therefore, the loader should unload the load before starting a fire and run it for a few minutes to allow the machine temperature and water temperature to cool down before shutting down.
