(Cote d 'Ivoire unidirectional cylinder,produced by Hebei Hengyu company）

unidirectional cylinder are widely used in Cote d 'Ivoire，because of simple structure and reliable operation，excellent temperature resistance，no transmission clearance.So our company has designed unidirectional cylinder for customers from Cote d 'Ivoire.

Introduction to unidirectional cylinder:

When the unidirectional cylinder is in use, once the seal and guide support ring are found to be defective, the seal with the same structural form and appropriate material should be replaced according to the structural form of the unidirectional cylinder seal to be repaired, so as to minimize the thickness of the oil film between the seal and the sealing surface and reduce the leakage of the seal.

The repair method of the unidirectional cylinder: the repair of the unidirectional cylinder must use brush plating. This is because this repair method can be carried out on site, and the repair effect is good. In this way, loading and transportation can be eliminated to shorten the repair time and improve work efficiency. In addition, the coating obtained by brush plating has good binding force and will not have obvious boundaries. Moreover, the repair surface has high hardness and good wear resistance.

How to repair the unidirectional cylinder body when it is damaged: When the unidirectional cylinder has trace deformation and shallow tensile marks, the unidirectional cylinder is repaired by strong honing process. The heavy honing process can repair unidirectional cylinders up to 2.5 times out of tolerance than the original tolerance. It honed the parts with excessive size or shape error through a powerful honing machine, so that the overall size, shape tolerance and roughness of the unidirectional cylinder can meet the technical requirements.

The wear of the hard chromium plating layer of the unidirectional cylinder is mostly caused by the grinding of the friction iron powder of the piston, and the wear is faster when there is water in the middle. Corrosion caused by the contact potential difference of the metal only occurs in the part of the piston contact, and the corrosion occurs in a point pattern. As mentioned above, when there is moisture in the middle, it will promote the development of corrosion. Compared with castings, the contact potential difference of copper alloy is higher, so the corrosion degree of copper alloy is more serious.

Answers to some questions about unidirectional cylinder:

Can a leak in the cylinder cause the hydraulic system to fail?
Leakage in the cylinder can cause the hydraulic system to fail. Cylinder leakage (internal leakage) first affects the controlled action of the hydraulic system can not meet the requirements (such as the movement speed of the cylinder, the insufficient thrust and tension of the cylinder), if the internal leakage of the cylinder is too large, it may also cause the cylinder to be unable to promote the load movement. Second, the existence of internal leakage (internal leakage) of the oil cylinder will lead to the rapid rise (or too high) of the oil temperature of the hydraulic system, and the high oil temperature will not only waste the energy conversion of the system, but also lead to the reduction of the viscosity of the oil, which will accelerate the aging and destruction of the seals such as pumps, valves, cylinders, pipelines, and at the same time, the lubrication effect of the hydraulic oil is reduced, and the production of iron filings that increase the friction of the hydraulic system.

Why does the hydraulic cylinder ring?
1 Air intrusion into the hydraulic system is the main reason for noise 2 The relief valve is unstable, such as due to the improper combination of the slide valve and the valve hole or the contact of the cone valve and the seat is stuck by dirt, the damping hole is blocked, the spring is crooked or fails to make the spool stuck or move in the valve hole, causing system pressure fluctuation and noise. 3 Improper adjustment of the reversing valve causes the spool of the reversing valve to move too fast, resulting in reversing impact, resulting in noise and vibration. 4 Mechanical vibration, such as long tubing, elbow more and not fixed, when the oil flow through, especially when the flow rate is high, easy to cause pipe shaking; The rotating part of the motor and hydraulic pump is unbalanced, or the alignment is not good during installation, or the coupling is loose, etc., which can produce vibration and noise.
