(Ireland servo hydraulic cylinder,produced by Hengyu Hydraulic Co., Ltd）

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

Introduction to servo hydraulic cylinder:

When producing oil servo hydraulic 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.

servo hydraulic cylinder body inspection: The inner surface of the servo hydraulic cylinder and the piston seal are the main factors causing the leakage in the servo hydraulic cylinder, if the servo hydraulic cylinder has a longitudinal tensile mark, even if the new piston seal is replaced, it can not effectively eliminate the fault, the inner surface of the servo hydraulic cylinder mainly checks whether the dimensional tolerance and shape and position tolerance meet the technical requirements, there is no longitudinal tensile mark, and measures the depth of the longitudinal tensile mark, in order to take the corresponding solution.

The servo hydraulic cylinder is mainly composed of body, piston, piston rod, servo hydraulic cylinder head, servo hydraulic cylinder bottom, piston rod head and related auxiliary devices. The piston divides the servo hydraulic cylinder into two chambers, and moves reciprocally in the servo hydraulic cylinder with the help of pressure oil. In order to improve its working effect, there is no sealing ring on the piston to eliminate internal leakage, where the piston rod passes through the servo hydraulic cylinder head, due to the existence of the gap, it is easy to produce external leakage phenomenon, and the dust can enter the servo hydraulic cylinder through the gap, so the sealing device and dust prevention reason are set. At the same time, in order to eliminate the influence of eccentric load on the work of the piston, all the servo hydraulic cylinders must be provided with a considerable length of guide sleeve at the extended end of the piston rod. In addition, in the case of faster piston movement, the phenomenon of mechanical collision between the piston and the servo hydraulic cylinder bottom and the servo hydraulic cylinder head is serious, so the buffer deceleration should be set at both ends of the servo hydraulic cylinder The working medium of the servo hydraulic cylinder: because it works at room temperature, the ordinary oil-type hydraulic oil can be selected; servo hydraulic cylinder sealing device: The use of Yx sealing ring, polyurethane (PU) and polytetrafluoroethylene (PTFE) materials combined to achieve a good sealing effect; Buffer mechanism of the servo hydraulic cylinder: The buffer structure of the servo hydraulic cylinder is to prevent the piston from colliding with the servo hydraulic cylinder head at the end of the stroke.

When installing the servo hydraulic cylinder, the axial ends of the servo hydraulic cylinder cannot be fixed. Due to the effect of liquid pressure and thermal expansion in the servo hydraulic cylinder, there is axial expansion. If the two ends of the servo hydraulic cylinder are fixed, all parts of the servo hydraulic cylinder will be deformed. When disassembling the servo hydraulic cylinder, it is strictly forbidden to hammer the servo hydraulic cylinder and the piston surface, such as the servo hydraulic cylinder hole and the piston surface is damaged, do not allow sandpaper grinding, to use a fine oil stone carefully grinding. The clearance between the guide sleeve and the piston rod should meet the requirements.

Answers to some questions about servo hydraulic cylinder:

How to repair if hydraulic shears cylinder oil leakage?
The hydraulic cylinder is generally disassembled and the sealing ring is replaced. There are generally two ways to install the ends of the hydraulic cylinder. The larger hydraulic cylinder is mostly flanged disc type, which is screwed to the middle cylinder block by several bolts, the bolts are removed, and the cylinder head is slowly pulled out. The smaller hydraulic cylinder, the cylinder block and the head itself are threaded, and the rotating end cap can be removed from the cylinder block. If you do not understand the hydraulic cylinder, it is best to ask someone to deal with it. It is easy to damage the sealing ring and internal surface during disassembly.

What's the use of three oil pipes on the cylinder?
The cylinder usually has an upper and lower oil chamber, one is connected to the upper oil chamber, one is connected to the lower oil chamber, sometimes a hydraulic lock will be added, that is, a hydraulic control check valve to prevent accidents when the oil pipe breaks, so the third pipe should be the control oil pipe of the hydraulic control check valve.
