Embodiment
Below in conjunction with accompanying drawing to its structure of implementation of the present utility model and working procedure:
See also Fig. 1 to shown in Figure 3, dynamic seal apparatus of the present utility model is provided with base plate 115, the sleeve block 108 that links to each other with the internal surface of base plate 115, an O RunddichtringO 110 that links to each other with sleeve block 108 with the internal surface of base plate 115 respectively, penetratingly be inserted in the shifting axle 101 in the sleeve block 108, respectively with sleeve block 108, link to each other with shifting axle 101 first, the second oil-free lubrication guide sleeve 104,109 and first, second y- type seal ring 102 and 111, wherein first y-type seal ring, 102 to the first oil-free lubrication guide sleeves 104 are more away from the close more base plate 115 of base plate 115, the second y-type seal rings 111 to the second oil-free lubrication guide sleeves 109.Described movable sealing structure also be provided be sheathed on sleeve block 108 and an end be connected to the air inlet sleeve 106 of the outer surface of base plate 115, respectively that link to each other with air inlet sleeve 106 and sleeve block 108 and be positioned at 104,109 of first, second oil-free lubrication guide sleeves a pair of the 2nd O RunddichtringO 107, be positioned at a pair of the 2nd O RunddichtringO 107
Between air inlet annular groove 114, be located on the air inlet annular groove 114 and the inlet hole 113 that runs through sleeve block 108 be installed in air inlet sleeve 106 on and the argon gas air inlet adjustment valve 105 that links to each other with air inlet annular groove 112.
The first oil-free lubrication guide sleeve 104 is identical with the structure of the second oil-free lubrication guide sleeve 109, is respectively equipped with fracture 13 on it and two suction ports 14 are vertically arranged, argon gas is charged to the lip place on first, second y-type seal ring 102,111.
