(Egypt supporting cylinder,produced by Hengyu Hydraulic Co., Ltd）

supporting cylinder are widely used in Egypt，because of smooth movement，high work efficiency，excellent fatigue and impact resistance.So our company has designed supporting cylinder for customers from Egypt.

Introduction to supporting cylinder:

When using the supporting cylinder product, be sure to operate safely in accordance with the specification documents provided by the manufacturer, and pay attention to protecting the supporting cylinder block. If the supporting cylinder block is damaged, it will cause adverse consequences: ① The material debris extruded from the scratch groove will be embedded in the seal, which may cause new scratch area marks while damaging the working parts of the seal during operation. ② Deterioration of the surface roughness of the inner wall of the supporting cylinder, increase friction, easy to produce crawling phenomenon. ③ Increase the internal leakage of the supporting cylinder, so that the working efficiency of the supporting cylinder is reduced.

The supporting cylinder is mainly composed of body, piston, piston rod, supporting cylinder head, supporting cylinder bottom, piston rod head and related auxiliary devices. The piston divides the supporting cylinder into two chambers, and moves reciprocally in the supporting 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 supporting cylinder head, due to the existence of the gap, it is easy to produce external leakage phenomenon, and the dust can enter the supporting 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 supporting 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 supporting cylinder bottom and the supporting cylinder head is serious, so the buffer deceleration should be set at both ends of the supporting cylinder The working medium of the supporting cylinder: because it works at room temperature, the ordinary oil-type hydraulic oil can be selected; supporting 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 supporting cylinder: The buffer structure of the supporting cylinder is to prevent the piston from colliding with the supporting cylinder head at the end of the stroke.

The supporting cylinder should be used as far as possible to avoid the transverse force, sometimes the piston rod to bear the transverse load is too large, especially do not force or pull the supporting cylinder, bite. Elimination method: When installing the supporting cylinder, ensure that the axis position of the supporting cylinder is consistent with the direction of movement; Make the load borne by the supporting cylinder as far as possible through the supporting cylinder axis, to avoid the phenomenon of eccentricity.

Before the supporting cylinder is removed, the relief valve should be loosened to reduce the pressure of the hydraulic circuit to zero, and then the power supply should be cut off to stop the hydraulic device. After loosening the oil port piping, the oil plug should be applied to plug the oil port.

Answers to some questions about supporting cylinder:

How many kinds of cylinder seal repair kit are there?
Very much, a wide variety of imported and domestic, J type, UHS, DHS, O-ring, Sterseal, etc., as well as support bars, materials are different, according to the size of the pressure selection is different, the appearance of the structure is different, the size is a variety, maintenance is generally selected according to the needs of the cylinder.

Is it good or bad for the hydraulic cylinder working in the limit stroke position?
It is not good for the hydraulic cylinder working in the limit stroke position. Generally, when the cylinder is used in the limit stroke, the oil in the cylinder will form a backflow back pressure impact on the piston and guide sleeve seals. If the limit is not accurate, it is easy to cause collision damage. It is recommended to leave a buffer of ten to twenty centimeters.
