The excavator long stick is very common nowadays, because it can better help the excavator to achieve earthwork excavation operations such as building foundations, river channels, deep trenches, etc.
Therefore, no matter how many or small faults the hydraulic system encounters, the owner will quickly find an engineer to solve the problem, but the editor wants to know that everyone will spend a lot of money when they encounter such a simple problem as hydraulic feed cylinder oil leakage.
There are also many domestic manufacturers of excavator oil cylinder. Unreasonable cause, in most cases, the manufacturer is to save costs.
Check whether the other end of the heavy duty hydraulic cylinder has oil, whether the solenoid valve is reversed, and whether the leakage of the cylinder is particularly serious. Whether the oil return line is blocked by foreign objects.
The so-called crawling of the excavator cylinder rod is that after the excavator closes the engine, under this static state, the cylinder rod will have a certain displacement.
Analysis of the reasons for the weakness of the excavator hydraulic cylinder and oil leakage
The excavator long front boom produced by Huitong Heavy Industry is a set of specially designed and manufactured excavator front-end working devices tailored to expand the working range of the excavator according to the requirements of special working conditions.
The whole double-cylinder hydraulic shears can be hydraulically rotated 360 degrees to improve the working ability. The special speed-increasing valve design can increase the working speed and penetrate the complex structure with huge shearing force.
The reliability of the excavator hydraulic system depends to a large extent on the design of the hydraulic system excavator seal kit and the selection of the oil seal.
The replacement of the excavator cylinder seal kit in the central rotary joint and the oil seal in the boom cylinder on the excavator is time-consuming and labor-intensive, and cannot be quickly replaced and repaired in the field due to the limitations of the site and equipment.
