Description
Technical field
The utility model relates to a kind of mechanical sealing element, specifically a kind of single mechanical end face seal part of architecture advances.
Background technique
Mechanical seal is by a pair of or several the end face of making relative sliding perpendicular to axle is kept applying and is equipped with auxiliary seal and reaches the gland seal device of Drain Resistance in that elastic force (or magnetic force) effect of hydrodynamic pressure and compensation mechanism is lower.It generally is comprised of elements such as stationary ring, rotating ring, elastic element, spring seat, Cock screw, auxiliary seal rings, and whether rotating ring and stationary ring can have the nose balance ability according to them toward contact is called compensated loop or non-compensation also.
The end face of rotating ring and stationary ring is fitted each other and is done the motive sealing of relative sliding, and it is the primary seal in the mechanical seal device, also is to determine mechanical sealing performance and the key in life-span.Therefore, very high to the processing request of seal face, keep necessary lubricating liquid film between seal face in order to make simultaneously, the compressive load per unit area on the end face processed of necessary strict chamber, pressure is excessive, is difficult for forming stable lubricating liquid film, can accelerate the wearing and tearing of end face; Pressure is too small, and leakage rate increases.So will obtain good sealability has again enough life-spans, when design and installation mechanical seal, must guarantee that end face compressive load per unit area value is in optimal scope.
The structure of the mechanical sealing element of present various single end faces is complicated, and is high to making processing request, so the single mechanical end face seal part of development of new structure has very real meaning.
The model utility content
The purpose of this utility model is to provide a kind of single mechanical end face seal part of architecture advances, can reach the lift-off seal effect by structural optimization and improvement, improves the Novel single end face mechanical sealing element of comprehensive sealing effect.
The technical scheme in the invention for solving the technical problem is: a kind of single mechanical end face seal part of architecture advances, comprise axle sleeve, stationary ring, rotating ring, rotating seat, spring, gland assembly and flange, it is characterized in that, described axle sleeve is nested with in flange hole, and be provided with the positioning plate that a restrictive axes that is stuck in the axle sleeve annular groove is overlapped axial play between described axle sleeve and flange, described axle sleeve can rotate with respect to flange;
One end of described axle sleeve is installed rotating seat and rotating ring;
But the side that is installed in flange that described stationary ring slides by spring and guiding round pin axial reciprocating, and the end face of the end face of described stationary ring and rotating ring matches;
Be fixedly connected with by screw between described rotating seat and axle sleeve, described axle sleeve and the rotating ring; And be provided with seal ring between described rotating seat and axle sleeve, described rotating seat and the rotating ring;
Be provided with sealing gasket and seal ring two seals between described stationary ring and the flange;
Described gland assembly is fixed on the axle sleeve of flange opposite side, comprises upper press cover and lower cover, and is wedge-like engagement between two glands, by bolton so that described gland assembly compressing axle sleeve and so that axle sleeve and axle fit in one.
Between described axle sleeve and axle, be provided with seal ring.
Be provided with the leakage recovery approach at described flange.
The beneficial effects of the utility model are: the utility model structure has certain improvement, has simplified part-structure, has improved sealability, and structure aspects has certain novelty.
Description of drawings
Fig. 1 is general assembly drawing of the present utility model;
Among the figure: 1 axle sleeve, 2 stationary rings, 3 rotating rings, 4 rotating seats, 5 springs, 6 gland assemblies, 7 flanges, 8 seal rings, 9 positioning plates, 11 upper press covers, 12 lower covers, 13 wedge-like engagement, 14 guiding round pins, 15 sealing gaskets, 16 reveal recovery approach.
Embodiment
As shown in Figure 1,
A kind of single mechanical end face seal part of architecture advances comprises axle sleeve 1, stationary ring 2, rotating ring 3, rotating seat 4, spring 5, gland assembly 6, flange 7, screw, sealing gasket and seal ring etc.
Axle sleeve 1 is for being nested with the part on pump shaft, and itself and axle closely cooperate, and are provided with seal ring 8 between axle sleeve and axle.Axle sleeve 1 is nested with in the flange hole of flange, in the both sides of flange extension is arranged all.(right side) is provided with the positioning plate 9 that a restrictive axes that is stuck in the axle sleeve annular groove is overlapped axial play between axle sleeve and flange, fix by screw between positioning plate and the flange, so lower fixing of positioning plate, axle sleeve only can rotate with respect to flange, and must not be at axial float.Low order end at axle sleeve 1, by one group of gland assembly axle sleeve is pressed on the axle, this gland assembly comprises upper press cover 11 and lower cover 12, and is wedge-like engagement 13 between two glands, by bolton so that described gland assembly compressing axle sleeve and so that axle sleeve and axle are tightened to one.That is to say that under the state of bolting on, lower cover can be close on the axle by wedge-like engagement face compressing upper press cover distortion and final compressing axle sleeve.
The left end of axle sleeve 1 is installed rotating seat 4 and rotating ring 3, and concrete mounting type is: be fixedly connected with by screw between described rotating seat and axle sleeve, described axle sleeve and the rotating ring; And be provided with seal ring between described rotating seat and axle sleeve, described rotating seat and the rotating ring.So axle sleeve, rotating seat and rotating ring form one, and rotate synchronously.
But the left side that is installed in flange 7 that stationary ring 2 slides by spring 5 and guiding round pin 14 axial reciprocatings, and the end face of the end face of stationary ring and rotating ring matches, and the fitting surface between rotating ring and the stationary ring is mechanical sealing surface.
Be provided with sealing gasket 15 and seal ring two seals between stationary ring and the flange, form static sealing effect.
Be provided with leakage recovery approach 16 at flange, can receive Outer Tube, the raffinate of revealing is recycled.
Except the described technical characteristics of specification, be the known technology of those skilled in the art.
