Detailed description of the invention
The present invention will be further described in detail with detailed description of the invention below in conjunction with the accompanying drawings.
As depicted in figs. 1 and 2, a kind of multistage support sealing mechanism of multi-stage booster pump, including the seal receptacle 2 being pressed on electric motor end cap 1, the rotating shaft 3 of described motor 101 is through seal receptacle 2, on described seal receptacle 2, also pressure is provided with a water-outlet body 4, described seal receptacle 2 caves inward away from one end of motor and forms cylindrical containing cavity 100, and this containing cavity is intrinsic pressure is provided with a mechanical seal body being set in rotating shaft 35.Seal receptacle 2 is compressed by electric motor end cap 1 and mechanical seal body 5 from two contrary directions, namely the both sides of seal receptacle 2 are all supported, and support strength significantly improves.
In the present embodiment, electric motor end cap 1 is provided with a cylindrical circular pressure-bearing cylinder 6, and this pressure-bearing cylinder 6 is formed to support with seal receptacle 2 lower surface and is connected.
Water-outlet body 4 is set in outside seal receptacle 2, seal receptacle 2 be provided with one outwardly and with water-outlet body 4 inwall be in close contact it is thus possible to water-outlet body 4 formed support support rim 7.The effect increasing structural strength is played in one end of water-outlet body 4 by support rim 7.Water-outlet body 4 includes water-outlet body straight tube 14 and the outlet 15 that be connected fixing with water-outlet body straight tube 14, and described water-outlet body straight tube 14 is provided with a concave station seam 16 away from one end of motor, and pump case can be pressed on concave station seam 16.Concave station seam 16 and the cooperation of support rim 7, make the structural strength at water-outlet body 4 two ends all be improved.
Seal receptacle 2 includes interconnective sealed end 8 and is tightly connected end 9, and support rim 7 is positioned at and is tightly connected end 9 and the junction of sealed end 8, and mechanical seal body 5 is positioned on sealed end 8.Being tightly connected end 9 and outwards turn down formation crimp rings 10 away from one end of sealed end 8, described water-outlet body 4 end is pressed in crimp rings 10, and crimp rings 10 is pressed on electric motor end cap 1, and Area of bearing is relatively big, has preferable support effect.Sealed end 8 includes the rib 11 in round platform taper and the supporting part 12 in annular being connected with rib 11, and described supporting part 12 is pressed on pressure-bearing cylinder 6.Supporting part 12 cave inward near the side of mechanical seal body 5 formed bottom there is the containing cavity of supporting surface 13.
Form sealing ring containing cavity 17 between crimp rings 10, support rim 7 and water-outlet body straight tube 14, in sealing ring containing cavity 17, be provided with sealing member.Crimp rings 10, support rim 7, be tightly connected end 9 and sealed end 8 one cold moudling.
The operation principle of the present invention is: seal receptacle 2 is all played a supporting role by electric motor end cap 1, mechanical seal body 5 and pressure-bearing cylinder 6, especially pressure-bearing cylinder 6 directly acts on the supporting part 12 of seal receptacle 2, the end face strength of seal receptacle 2 is played reinforcement by rib 11, therefore pressure-bearing cylinder 6 also functions to the effect strengthening supporting on supporting part 12, thus improves sealing effectiveness.
Water-outlet body straight tube 14 front end has stamped out concave station seam 16, add the intensity of front end, rear end is straight barrel type, insufficient strength, therefore the support rim 7 of seal receptacle 2 and water-outlet body straight tube 14 inwall close-fitting, after assembling, be equivalent to the direct tube section having an inner supporting circle to support water-outlet body straight tube 14, thus add the intensity of water-outlet body straight tube 14 rear end.During assembling, water-outlet body straight tube 14 is directly socketed on seal receptacle 2 installation, quick and easy for installation.
Specific embodiment described herein is only to present invention spirit explanation for example.Described specific embodiment can be made various amendment or supplements or use similar mode to substitute by those skilled in the art, but without departing from the spirit of the present invention or surmount scope defined in appended claims.
Although the most more employing electric motor end cap 1, seal receptacle 2, rotating shaft 3, water-outlet body 4, mechanical seal body 5, pressure-bearing cylinder 6, support rim 7, sealed end 8, being tightly connected the terms such as end 9, crimp rings 10, rib 11, supporting part 12, supporting surface 13, water-outlet body straight tube 14, outlet 15, concave station seam 16, sealing ring containing cavity 17, but it is not precluded from using the probability of other term.Use these terms to be only used to more easily to describe and explain the essence of the present invention；It is all contrary with spirit of the present invention for being construed as any additional restriction.
