Description
Technical Field
The utility model belongs to the technical field of machinery, concretely relates to mechanical seal structure in impeller pump.
Background
Present rotor pump, including the box and the pump body that link firmly mutually, wear to establish pivot and install the rotor in the pump body in the box and link to each other, in order to guarantee that the medium in the pump body can not leak to the box, install mechanical seal in the pivot usually, mechanical seal includes quiet ring and rotating ring, wherein quiet ring is located the box, the rotating ring is located the pump body, this structure can reach good mechanical seal, but because the installation of quiet ring and rotating ring is on different positions, it is more troublesome in the actual installation, it is inconvenient to bring for subsequent maintenance.
Disclosure of Invention
The utility model aims at solving the problems in the prior art, and provides a mechanical sealing structure in a rotor pump, which has simple structure, is practical and convenient.
The purpose of the utility model can be realized by the following technical proposal: the utility model provides a mechanical seal structure among rotor pump, install in the pump body, wear to be equipped with the pivot in the pump body, a serial communication port, including rotating ring and the quiet ring that contacts, install the rotor that links to each other with the pivot in the tip before the pump body, rotor face has seted up ring groove on the terminal surface of the tip behind the pump body, the rotating ring is installed in ring groove, the annular groove has been seted up in the tip behind the pump body, quiet ring is installed in the annular groove, the constant head tank has been seted up on the terminal surface of quiet ring face towards the pump body rear end portion, be equipped with the spring in the constant head tank and spring one end supports and leans on at the constant head tank bottom, the other end supports and leans on at the annular groove bottom, seal installation has the sealing washer between the outer terminal surface of.
Compared with the prior art, the utility model has the advantages of it is following: the static ring and the rotating ring in the mechanical seal are all installed in the pump body, wherein the rotating ring is installed on a rotor in the pump body, the static ring is installed in the rear end portion of the pump body, meanwhile, the static ring and the rotating ring are in close contact through spring extrusion, when the mechanical seal is actually installed, the spring and the static ring are installed in the pump body, then the rotating ring is installed in the rotor, and finally the rotor is installed on the pump body. Because quiet ring and rotating ring all install in the pump body, when maintaining the change, also only need with the pump body dismantle alone can, in the purchase in-process, the rotating ring can be purchased respectively with quiet ring moreover, simultaneously through sealing washer and sealing ring, can be so that the rotor in the pump body is at the rotation in-process, its inside medium can not leak out from mechanical seal, sealed effectual.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
Fig. 2 is a schematic diagram of the structure at a in fig. 1.
In the figure, 1, a pump body; 11. an annular groove; 2. a rotating shaft; 3. a rotor; 31. an annular neck; 4. a moving ring; 5. a stationary ring; 51. positioning a groove; 6. a spring; 7. a seal ring; 8. and (4) a sealing ring.
Detailed Description
The following are specific embodiments of the present invention and the accompanying drawings are used to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.
As shown in figures 1 and 2, the mechanical sealing structure of the rotor pump is arranged in a pump body 1, a rotating shaft 2 is arranged in the pump body 1 in a penetrating way and comprises a movable ring 4 and a static ring 5 which are contacted with each other, a rotor 3 connected with the rotating shaft 2 is arranged in the front end part of the pump body 1, an annular clamping groove 31 is arranged on the end surface of the rotor 3 facing the rear end part of the pump body 1, a movable ring 4 is arranged in the annular clamping groove 31, an annular groove 11 is arranged in the rear end part of the pump body 1, the static ring 5 is arranged in the annular groove 11, a positioning groove 51 is arranged on the end surface of the stationary ring 5 facing the rear end part of the pump body 1, a spring 6 is arranged in the positioning groove 51, one end of the spring 6 is propped against the bottom of the positioning groove 51, the other end of the spring 6 is propped against the bottom of the annular groove 11, and a sealing ring 7 is arranged between the outer end surface of the static ring 5 and the inner wall of the annular groove 11 in a sealing way, and a sealing ring 8 is arranged between the outer end surface of the movable ring 4 and the inner wall of the annular clamping groove 31 in a sealing way. The mechanical seal is characterized in that a static ring 5 and a movable ring 4 are all installed in a pump body 1, wherein the movable ring 4 is installed on a rotor 3 in the pump body 1, the static ring 5 is installed in the rear end portion of the pump body 1, meanwhile, the static ring 5 and the movable ring 4 are in close contact through extrusion of a spring 6, the spring 6 and the static ring 5 are installed in the pump body 1 firstly, the movable ring 4 is installed in the rotor 3, and finally the rotor 3 is installed on the pump body 1. Because quiet ring 5 and rotating ring 4 all install in the pump body 1, when maintaining the change, also only need with the pump body 1 dismantle alone can, moreover in the purchase process, rotating ring 4 and quiet ring 5 can be purchased respectively.
Meanwhile, by the sealing ring 7 and the sealing ring 8, the medium in the rotor 3 in the pump body 1 cannot leak out from the mechanical seal in the rotating process, and the sealing effect is good.
The specific embodiments described herein are merely illustrative of the spirit of the invention. Various modifications, additions and substitutions for the specific embodiments described herein may be made by those skilled in the art without departing from the spirit of the invention or exceeding the scope of the invention as defined in the accompanying claims.
