Today Xiao Bian talked to you 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 pick up the whole Earth". The principle of the hydraulic cylinder of the dump truck is similar to this. No matter what the weight is, a manual pressurization by a simple hydraulic cylinder allows the hydraulic fluid to enter the hydraulic cylinder, so that the hydraulic fluid cannot be returned due to the check valve's obstruction. Push the cylinder rod upwards. Then the dump trucks began to rise. The principle of descent is the same. Open the hydraulic valve and let the hydraulic oil return to the tank. This completes the work of the dump.

Understand the working principle of the dump truck to get a better job. How do you do the daily maintenance of the dump truck in your operation? The following Xiaobian summed up the following points for reference:

First of all, the routine inspection of the fuel tank should be done frequently. Although the material of the fuel tank is generally hard and there will be no problem, once the problem occurs, the consequences are serious; therefore regular inspection is often necessary.

Secondly, before re-use, we must first check whether the amount of hydraulic oil is sufficient, whether the system is damaged, whether the link between link mechanisms is reliable, whether the compartment, power take-off, etc. are intact.

In the process of use, the pressure should be zeroed firstly. If the pressure is too high, the oil will be sprayed outwards; when disassembling, the threads on the piston rod should be protected to prevent damage. In addition, different disassembly methods are selected according to the different cylinders.

After the final use is completed, it is also necessary to promptly complete troubleshooting and routine inspections. If everything is in good condition, maintenance can be done once, and timely cleaning and maintenance are also necessary. I hope this article from Xiaobian can help you!
