ZH 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, the oil The fluid passes through the smaller orifice to form a very thin oil film, thus replacing ordinary seals to achieve the sealing effect. It is more cost-effective than the static pressure support. Since the contact seal and dust ring do not bear pressure, the piston The rod is guided by friction-optimized guide elements, so the starting friction in the entire pressure range is very low, thus ensuring the high dynamics and long service 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.
