(Thailand retractable cylinder,produced by Hengyu Hydraulic Co., Ltd）

retractable cylinder are widely used in Thailand，because of excellent fatigue and impact resistance，no need for deceleration device，long service life.So our company has designed retractable cylinder for customers from Thailand.

Introduction to retractable cylinder:

When the long-stroke retractable cylinder rotates horizontally, the piston rod bends due to its own weight, causing the guide sleeve and piston to produce biased load, resulting in retractable cylinder head seal damage, oil leakage, and piston sleep in the retractable cylinder. The following measures can be taken: increase the piston plan to adjust the piston outer circle and process it into a convex drum, so that the piston can self-position, improve the force situation, and reduce and avoid pulling the retractable cylinder; The piston and the piston rod are connected with a spherical joint.

How to repair the retractable cylinder body when it is damaged: When the retractable cylinder has trace deformation and shallow tensile marks, the retractable cylinder is repaired by strong honing process. The heavy honing process can repair retractable 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 retractable cylinder can meet the technical requirements.

When producing oil retractable cylinders, there are two processing processes, grinding and rolling, the latter is better than the former. Rolling machining is a kind of non-cutting machining, using the plastic deformation of the metal at room temperature, so that the micro roughness of the workpiece surface is flattened to achieve the purpose of changing the surface structure, mechanical characteristics, shape and size. Therefore, this method can achieve the two purposes of finishing and strengthening at the same time, which can not be done by grinding.

The difference between the integral retractable cylinder and the split retractable cylinder: The integral retractable cylinder and the split retractable cylinder in the retractable cylinder are two different retractable cylinders, and they are very different. The whole retractable cylinder, which is cast in one body, is not prone to problems such as oil leakage; The split retractable cylinder is welded twice, so if it is not handled well at the welding, it is prone to problems such as oil leakage and retractable cylinder damage. Therefore, it is obvious that the answer to this question is for difference.

Answers to some questions about retractable cylinder:

A hydraulic system functions three cylinders to maintain pressure, what components need to be used?
Two way cartridge valve can be selected for control. Two way cartridge valve advantages: 1) flow capacity is large, especially suitable for large flow occasions. 2) The spool has sensitive action and strong anti-clogging ability. 3) Good sealing, small leakage, oil flow through the valve pressure loss is small. 4) Simple structure, easy to standardize.

Can multiple identical hydraulic cylinders be supplied with the same supply line?
This can be connected, but there is a disadvantage, that is, the hydraulic cylinder with the minimum pressure is extended first, and then the pressure is higher, and then the higher, until all the hydraulic cylinders are extended, which may not meet the requirements of field use.
