High-end Servo Hydraulic Cylinder

Functional uses:

In the dynamic test environment, a stable, low friction hydraulic cylinder is needed. This hydraulic cylinder provides two types of test cylinders with minimal friction. High manufacturing accuracy with small guide clearance ensures wear-free operation, thus prolonging service life.

咨询热线: Product characteristics:High speed (up to 50 m/s);High frequency (up to 1000HZ);Long life (more than 5 years);Low friction (below 0.01 MPA).Sealing of high-end servo hydraulic cylinder:1. Hydrostatic bearing has hydrostatic piston rod guide device, rod guide device and seal in one component. The piston rod floats on a layer of oil film and can withstand large transverse shear force. The pressure supply of hydrostatic bearing is realized by the inner structure of the cylinder, which can withstand large lateral force. Because the contact seal and dust ring do not withstand pressure, the residual friction force in the whole pressure range is very small, which ensures the high dynamic and long service life of the servo hydraulic cylinder.2. Ring gap seal is a kind of non-contact seal. Because of the pressure difference, the oil can form a thin oil film through a small throttle hole, thus replacing the ordinary seal to achieve the sealing effect, but the maximum lateral force it bears is limited. Because the contact seal and dust ring do not withstand pressure, the piston rod is guided by a guide element optimized for friction, so the starting friction in the whole pressure range is very small, which guarantees the high dynamic performance and long service life of the servo hydraulic cylinder.Applications: Various tension and pressure testing machines, multi-degree-of-freedom swing table, dynamic simulation of aircraft and automotive parts, high-speed and long-life requirements for machine tools, injection moulding machines and stamping machines.

The blade type high-end servo swing cylinder is divided into two types: single blade and double blade. The seal adopts clearance seal form, which has extremely high dynamic performance. The maximum torque is 100,000 NM and the maximum working pressure is 300 BAR. Emergency buffer and adjustable buffer can be designed at both ends. An angle encoder can be installed at the tail of the output shaft to provide real-time tracking feedback for the swing of the swing cylinder.
