Working Principle And Daily Maintenance Of Hydraulic Cylinder Of Dump Truck

Working principle and daily maintenance of hydraulic cylinder of dump truck.
Today, we will talk about the principle and daily maintenance of the hydraulic cylinder of the dump truck, the well-known ancient Greek physicist Archimedes once said such a sentence: "Give me a fulcrum, I can pry up the whole earth." The principle of the hydraulic cylinder of the dump truck is similar to this, no matter how much weight is faced, through a simple manual pressurization of the cylinder, the hydraulic oil enters the cylinder, so that the hydraulic oil cannot be returned because of the obstruction of the check valve, so as to promote the cylinder rod upward. Then the dump car began to rise. The lowering principle is the same, opening the hydraulic valve to let the hydraulic oil return to the tank, so as to complete the self-unloading work.
Daily maintenance of hydraulic cylinder of dump truck:
1. The routine inspection of the cylinder should be done often. Although the material of the cylinder is relatively hard, there will generally be no problems, but once there is a problem, the consequences are very serious; So it is necessary to have regular check-ups.
2. Before use, first check whether the hydraulic oil is sufficient, whether the system is damaged, whether the link between the connecting rod mechanism is reliable, whether the carriage and the force extractor are intact.
3. In the process of use, the pressure must first be zero, too high pressure will cause the oil to spray out; Disassembly is to pay attention to protect the screw threads on the piston rod to avoid damage. In addition, different disassembly methods are selected according to different cylinders.

4. After the completion of the use, it is also necessary to timely troubleshooting and routine testing, if everything is in good condition, you can also do a maintenance, timely cleaning and maintenance is also necessary.
