The annular gap seal can effectively reduce the friction during the movement of the hydraulic cylinder. It has obtained domestic and foreign patents, U.S. Patent No.
The annular gap seal is a non-contact seal. Due to the pressure difference, , allowing the oil to pass through the smaller orifice to form a very thin oil film, thereby replacing ordinary seals to achieve the sealing effect. It is more cost-effective than static pressure supports, because the contact seals and dust rings cannot withstand Pressure, the piston rod is guided by friction-optimized guide elements, so the starting friction in the entire pressure range is very small, thus ensuring the high dynamics and long life of the servo hydraulic cylinder. Application fields: various tensile and compression testing machines, vibration swing tables, dynamic simulation of aircraft and automobiles and their parts.
