The dump truck is a relatively common vehicle in daily operations. Its working principle is mainly achieved through hydraulic lift. The main components include a fuel tank, a check valve, a solenoid valve, a hydraulic oil gear pump, and a hydraulic cylinder. . Mainly through the start of the hydraulic oil gear pump, the tank hydraulic oil is continuously pressurized along the pipeline pump to the hydraulic cylinder. When the plunger in the hydraulic cylinder rises and the pump fluid stops, the pump fluid returns to the tank. What is the specific working principle? With a small series to see detailed operating schematic!
To ensure safe operation, the dump truck should not be able to push the handle to the descending position suddenly during the lifting. Such an operation will bring severe impact to the carriage, which may cause serious accidents. Therefore, the first important point is to control the speed of landing and avoid suddenly throwing the car to the end.
Second, because the vehicle is heavier, there is an inertia in the weight and the speed of the goods when unloading. Fast brakes will, to a certain extent, lead to permanent deformation of the vehicle and welding cracking of the carriage and destruction of the seal ring. It may also reduce the service life of the vehicle. In severe cases, a rollover accident may occur, resulting in irreversible damage.
Finally, after the dump truck has finished unloading, it must remove the power take-off before it can drive. If you do not drive off the PTO, it will cause the hydraulic oil temperature to rise quickly, which will result in the damage of the oil pump seal. In severe cases, the oil pump may be burned or the car may rise automatically.
Therefore, Xiao Bian reminds everyone here that we must fully understand the working principle of the dump before operating the dump truck. Learn more about the precautions for the next operation and some simple fault judgments so that you can work more safely. It is also responsible for the safety of oneself and others. I hope this article from Xiao Bian can help you, thank you for your visit!
