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

Introduction to clamp type cylinder:

The piston rod and guide sleeve function of the clamp type cylinder is crucial: the relative motion pair between the piston rod and the guide sleeve is the main factor causing external leakage, if the chrome layer on the surface of the piston rod is spalling or producing longitudinal tensile marks due to wear, it will directly lead to the failure of the seal.

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

The definition of the minimum stable speed refers to the minimum movement speed of the clamp type cylinder without crawling phenomenon when the full load is moving, it has no uniform indicator, and the clamp type cylinder that undertakes different work has different requirements for the minimum stable speed.

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

Answers to some questions about clamp type cylinder:

What valve is used to control the speed of the cylinder?
Hydraulic cylinder for lifting is generally the piston rod downward installation, to achieve the fast and slow speed of the cylinder, you can add a two-digit three-way electromagnetic reversing valve + a throttle valve on a branch at the bottom of the cylinder, you can achieve speed change, control mode can be controlled by time control can also be controlled by stroke switch. If you want to achieve more accurate control can use proportional valve control.

Is the hydraulic cylinder leaking because there is no pressure?
HC hydraulic cylinder common leakage reasons, first: most of the reasons are because the seal surface wear or aging leads to poor sealing, so there is no pressure to operate, as long as the piston seal can be replaced. Second: It may also be the piston rod strain, repair the piston rod is good. If it is because the piston strength is not enough and the playing time is long, it is necessary to replace the piston.
