tailplate hydraulic cylinder are widely used in Dominica，because of powerful torque，clever hydraulic energy conversion，simple structure and reliable operation.So our company has designed tailplate hydraulic cylinder for customers from Dominica.

Introduction to tailplate hydraulic cylinder:

Before the tailplate hydraulic cylinder is removed, the system should be unloaded, the loop pressure is zero, the oil source should be cut off, and the oil port should be blocked after the oil port distribution pipe is loosened.

tailplate hydraulic cylinder spool stuck or valve hole blocked How to solve: When the flow valve or direction valve spool stuck or valve hole blocked, the tailplate hydraulic cylinder prone to misoperation or action failure. At this time, the contamination of the oil should be checked; Check whether dirt or colloidal deposits are stuck in the spool or blocking the valve hole; Check the wear of the valve body, clean and replace the system filter, clean the fuel tank, and replace the hydraulic medium.

The cavitation of the tailplate hydraulic cylinder has a great influence, and to avoid it, it is necessary to use the hydraulic oil reasonably and ensure the quality of the hydraulic oil. If the anti-foam property of the oil is poor, it is easy to produce foam, resulting in cavitation. Secondly, the change frequency of oil pressure is too fast and too high, which will also directly cause the formation of bubbles and accelerate the rupture rate of bubbles. The test shows that the speed of cavitation will be accelerated in the part with high frequency of pressure change. For example, at the inlet and outlet of the tailplate hydraulic cylinder, due to the relatively high frequency of pressure changes, the degree of cavitation is also relatively higher than that of other parts. In addition, overheating of the oil will also increase the probability of cavitation.

After chrome plating of the piston rod of the tailplate hydraulic cylinder, the surface flatness is not fully treated: After chrome plating of the piston rod surface, the method of post-plating polishing should be changed to post-plating polishing. Although it is necessary to increase the thickness of the coating before grinding (generally increased by about 0.02 in the diameter direction), it can remove chrome plating defects well, and test the binding force of the coating. In addition, due to the micro-roughness of the grinding surface, the trough can store lubricating oil, which can improve the wear resistance and extend the service life.

Answers to some questions about tailplate hydraulic cylinder:

How to control the speed of the cylinder?
High demand control, it is necessary to use servo closed-loop control, you can adjust the speed at will. Reference: Hydrodynamic Motion Control Practical Design Guide.

What is the function of the hinged cylinder of the shield machine?
The articulated cylinder is used for the shield when the radius of curvature is very small during the propulsion process, that is, for turning. For example, a propulsion section with a radius of curvature of R150 can only be turned using an articulated system due to the sensitivity of the shield body (i.e. the length of the shield body divided by its outside diameter). However, in the construction process, the use of articulated systems is not much.
