Described spring fixed seat outer wall also is provided with and the driver slot driving arm to match.
Described driver slot is arc groove.
Described rotating ring and groove are matched in clearance.
Described rotating ring includes annulus body and is located at the annulus boss of annulus body one end, and described annulus boss diameter is less than the diameter of annulus body；The outer face of described annulus boss realizes movable sealing with stationary ring and contacts, and driver slot is in the outer wall of annulus body；The described annulus body other end is provided with locating slot, and sealing ring mates in locating slot.
Described rotating ring is graphite material, and stationary ring, stationary ring are fixed seat and be ceramic material.
What this utility model can reach has the technical effect that
Compared with prior art, the mechanically-sealing apparatus spinned prevented by self priming pump of the present utility model, rotating ring fixed support uses the assembling structure of flat axis hole and flat axle with pump shaft, so, pump shaft is when starting or stoping, its with mechanically-sealing apparatus not compared with inertia motion, it is to avoid the abrasion that friction causes, extend service life；
Compared with prior art, the mechanically-sealing apparatus spinned prevented by self priming pump of the present utility model, be provided with spring fixed seat between spring and rotating ring, it is to avoid spring directly contacts with rotating ring, extends the service life of spring and rotating ring.

Fig. 3 is the axonometric chart of rotating ring of the present utility model.
Detailed description of the invention
With detailed description of the invention, this utility model is described in further detail below in conjunction with the accompanying drawings:
Refer to Fig. 1, Fig. 2, this utility model provides a kind of self priming pump to prevent the mechanically-sealing apparatus spinned, seat 7 is fixed with stationary ring including the rotating ring fixed support 2 being set on pump shaft 1, spring 3, spring fixed seat 4, rotating ring 5, stationary ring 6, described spring 3, spring fixed seat 4 and rotating ring 5 are plugged in the groove 8 of rotating ring fixed support 2 successively, spring 3 one end is against groove 8 inwall of rotating ring fixed support 2, and the other end is against on spring fixed seat 4；Described rotating ring 5 outer wall is provided with multiple driver slot 9, and accordingly, the inwall at rotating ring fixed support 2 has multiple driving arm 10, drives arm 10 to mate driver slot 9；It is provided with sealing ring 11, it is preferable that sealing ring 11 is O between described rotating ring 5 inwall and pump shaft 1；Having flat axis hole 12 on rotating ring fixed support 2, pump shaft 1 is arranged in flat axis hole 12, and the cross section being in pump shaft 1 at flat axis hole 12 is consistent with flat axis hole 12；By the rotation of pump shaft 1, thus rotating ring fixed support 2, rotating ring 5 is driven to rotate；Described stationary ring 6 is arranged on stationary ring and fixes in seat 7, and stationary ring 6 mates with rotating ring 5 and constitutes friction pair simultaneously.
Described spring fixed seat 4 outer wall also is provided with and the driver slot 13 driving arm 10 to match.
Described driver slot 9 is arc groove.
Described rotating ring 5 is matched in clearance with groove 8, and interval, gap is 1mm ~ 2mm.
As it is shown on figure 3, described rotating ring 5 includes annulus body 14 and the annulus boss 15 being located at annulus body 14 one end, described annulus boss 15 diameter is less than the diameter of annulus body 14；The outer face of described annulus boss 15 realizes movable sealing with stationary ring 6 and contacts, and driver slot 9 is in the outer wall of annulus body 14；Described annulus body 14 other end is provided with locating slot 16, and sealing ring 11 mates in locating slot 16.
