Installation and removal of the ceramic factory used hydraulic seals, in order to prevent the hydraulic plastic strap seal is threaded, undercut such an acute angle to scratch the sealing performance, we must adopt the following measures:
A) shall cylinder, piston, piston rod and the guide sleeve ends and other uses 15 ~ 30 ° angle smooth introduction.
2) When the hydraulic seals must pass male or retraction bad, they should put in their respective positions on the special sleeve, you can also make the outer diameter of the external thread or undercut the hydraulic diameter less than the inner diameter of the seal.
3) When the hydraulic seal to the internal thread or radial through holes, should the inner diameter or radial threaded hole is larger than the diameter of the outer diameter of hydraulic seals.
4) To reduce the hydraulic meter seals installation and removal of resistance, hydraulic seals should be subject to the appropriate location on the coated lithium soap grease or hydraulic working oil, hydraulic seals and try to avoid excessive stretching, in order to avoid the plastic deformation affecting the hydraulic seal of the sealing performance.
