Description
Technical field:
The utility model relates to a kind of mechanical seal device, the mechanical seal device of especially a kind of chemical pump that is used for centrifugal pump, pipeline mounted pump, sewage pump, oil pump and weak corrosion etc.
Background technique:
At present, the prior art mechanical seal device generally comprises static components and moving ring assembly; Described static components comprise stationary ring and be enclosed within on the stationary ring and with the friction tight stationary ring pad of the pump housing; Described moving ring assembly comprises rotating ring, support, rotating seat, fastening ring, spring and spring seat; End face of described rotating ring and stationary ring end face are fitted, the end face applying of its another end face and described support stub end; The little head end of described support is held tightly on axle by fastening ring; One end of described rotating seat is inserted on the groove of described fastening ring, and its other end realizes that by the cooperation of the R groove on rotating seat drive lug and the rotating ring transmission cooperates; Described spring is supported between rotating seat and the spring seat.The working principle of the mechanical seal device of said structure is: when axle rotates, axle and support can be by the power of holding tightly the transmissions of fastening ring, the moving rotating seat of the troughed belt of fastening ring rotates, rotating seat drives the rotating ring rotation by drive lug, under the effect of spring restoring force, end face of described rotating ring and stationary ring end face form motive sealing face, another end face of described rotating ring and the end face of support stub end formation static seal face.There is a deficiency when mounted in the mechanical seal device of said structure: because rotating ring just cooperates by itself R groove and the lug transmission on the rotating seat, and the relation of also just fitting between rotating ring and the support, therefore rotating ring is taken off easily when pump chamber is installed the mechanical seal device of said structure, thereby not only cause the breakage of rotating ring, but also bring certain trouble for the installation of whole mechanical seal device because need reinstall rotating ring.
The model utility content:
The technical problems to be solved in the utility model is, provides a kind of its rotating ring when mounted can not take off, thereby both avoided the breakage of rotating ring, can not influence the mechanical seal device of whole erection program again.
Technical solution of the present utility model is, a kind of mechanical seal device with following structure is provided, and it comprises static components and moving ring assembly; Described static components comprise stationary ring and be enclosed within on the stationary ring and with the friction tight stationary ring pad of the pump housing; Described moving ring assembly comprises rotating ring, support, rotating seat, fastening ring, spring and spring seat; Fit in the left side of described rotating ring and stationary ring right side; Fit in the right side of described rotating ring right side and described support; Described support is held tightly on axle by fastening ring; Described rotating seat right part is inserted in the groove of described fastening ring, and the rotating seat left part cooperates with the rotating ring transmission; Described spring is supported between rotating seat and the spring seat; The left end of described rotating seat can be provided with two or more rotating ring mousing-hooks; Described rotating ring mousing-hook is hooked on the step of rotating ring.
After adopting above structure, compared with prior art, the utlity model has following advantage: because rotating seat is provided with the rotating ring mousing-hook that is hooked on the rotating ring step in the utility model, therefore rotating ring can not taken off when the pump housing is installed the utility model, thereby both avoided the breakage of rotating ring, and can not influence normal mounting program of the present utility model again.
Description of drawings:
Accompanying drawing is the structural representation of the utility model mechanical seal device.
The pump housing as shown in the figure, 1, stationary ring, 2, the stationary ring pad, 3, rotating ring, 4, support, 5, rotating seat, 6, fastening ring, 7, spring, 8, spring seat, 9, axle, 10, groove, 11, the rotating seat drive lug, 12, the rotating ring mousing-hook, 13.
Embodiment:
The utility model is described in further detail below in conjunction with the drawings and specific embodiments:
As shown in drawings, in this specific embodiment, the utility model mechanical seal device comprises static components and moving ring assembly; Described static components comprises stationary ring 1 and stationary ring pad 2; Described stationary ring pad 2 is enclosed within on the stationary ring 1, because stationary ring pad 2 outer surfaces are provided with screw thread and its outside dimension inner cavity size greater than the pump housing 13, so is drive fit between the stationary ring pad 2 and the pump housing 13; Described moving ring assembly comprises rotating ring 3, support 4, rotating seat 5, fastening ring 6, spring 7 and spring seat 8; Fitting in the right side of the left side of described rotating ring 3 and stationary ring 1, fits in the right side of the right side of rotating ring 3 and described support 4; Described support 4 is held tightly on axle 9 by fastening ring 6; The right part of described rotating seat 5 is inserted in the groove 10 of described fastening ring 6; Described rotating seat 5 rotating rings 3 transmissions cooperate and refer to: the left part of described rotating seat 5 is provided with rotating seat drive lug 11, and described rotating ring 3 is provided with the R groove that cooperates with rotating seat drive lug 11, and described rotating ring 3 and rotating seat 5 can circumferentially rotate under the drive of fastening ring 6; Described spring 7 is supported between rotating seat 5 and the spring seat 8; The left end of described rotating seat 5 is provided with three rotating ring mousing-hooks 12, and described rotating ring mousing-hook 12 is as a whole with rotating seat 5; Described rotating ring mousing-hook 12 is hooked on the step of rotating ring 3.Because working principle of the present utility model is same as the prior art, so do not give unnecessary details at this.
The utility model is not limited to described in the foregoing description, and promptly the rotating ring mousing-hook 12 on the rotating seat 5 is can be not as a whole and just be connected on the rotating seat 5 with rotating seat 5 in the utility model; In addition, the quantity of rotating ring mousing-hook 12 also is not limited to three, and it can be two, four or five, more than changes all falling into protection domain of the present utility model.
