(France trailer hydraulic cylinder,produced by Hengyu Hydraulic Co., Ltd）

trailer hydraulic cylinder are widely used in France，because of no need for deceleration device，long service life，smooth movement.So our company has designed trailer hydraulic cylinder for customers from France.

Introduction to trailer hydraulic cylinder:

The cavitation of the trailer 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 trailer 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.

When the piston speed of the trailer hydraulic cylinder is high, the steel ball of the check valve flows with the oil flow, so that the valve hole is blocked, and the trailer hydraulic cylinder moves irregularly. Elimination method: Replace the steel ball with a cone valve or spool with a guide shoulder.

Most of the failure of the trailer hydraulic cylinder is because there is a foreign body in the trailer hydraulic cylinder into the failure of the trailer hydraulic cylinder, the most problematic is that it is difficult to determine when the foreign body is into the trailer hydraulic cylinder. After a foreign body enters, if the outer side of the sliding surface of the piston is equipped with a seal with a lip edge, then the lip edge of the seal can scrape the foreign body when working, which is beneficial to avoid scratching. However, the piston equipped with 0-shaped sealing ring has a sliding surface at both ends, and foreign bodies are sandwiched between this sliding surface, which is easy to form scars.

trailer hydraulic cylinder and hydraulic station selection: Select the type and structure of the trailer hydraulic cylinder according to the operation requirements of the main engine. According to the external load force borne by the trailer hydraulic cylinder, such as gravity, friction force of the external mechanism, inertia force and working load, determine the load change law of the trailer hydraulic cylinder in each stage of the stroke and the power value that must be provided. Determine the diameter of the piston and piston rod according to the working load of the trailer hydraulic cylinder and the selected oil working pressure. the flow rate of the hydraulic pump is determined according to the movement speed of the trailer hydraulic cylinder, the diameter of the piston and the piston rod.

Answers to some questions about trailer hydraulic cylinder:

What is the material of the cylinder support ring?
Generally, it is polytetrafluoroethylene doped with copper powder, or polyformaldehyde, and copper sleeves, there are also nylon, resin and so on.

For a cylinder with a piston diameter of 100mm and a system pressure of 10MPa, what is the thrust?
Thrust is 7850 kg. Piston area A= πR^2=7850 square mm =78.5 square cm 10MPa = 100kg/cm^2 "^2" is square F = A x P =78.5 x 100=7850 kg.
