Abstract

The utility model relates to a desulfur pump packaging type mechanical sealing element, comprising an end-face seal composed of a movable ring and a stator ring. The movable ring and a movable ring system composed of a movable ring seat fixed with the movable ring are fixedly arranged on the outer end of the shaft sleeve; the stator ring, a thrust ring contacting to the inner end surface of the stator ring, and a stator ring system composed of a spring and a spring seat are fixedly arranged in the center of the gland; the thrust ring takes a T shape, and is thrust by the spring arranged in the spring seat; the end surface in the spring seat is provided with a limited baffle plate; the gland is fixed on a pump body ento-ectad. The mechanical sealing element of the utility model adopts the assembling type structure, thus, which largely facilitates the installing, the debugging and the repairing of the large scale equipment; simultaneously dismounting the heavy pump body is avoided while in mounting and dismounting; the installation accuracy is improved, and the working strength is abated. The desulfur pump packaging type mechanical sealing element overcomes the defects of complex installation and debugging and big difficulty degree of the separate installing of the component adopted by the prior art.

Description

Desulfur pump integrated mechanical sealing spare

Technical field

The utility model relates to a kind of mechanical sealing element, is a kind of being arranged between turning axle and the machinery, the mechanical sealing element that stops the equipment inner fluid to leak.

Prior art

Leak for the place, slit of flowing medium between the desulfur pump pump shaft and the pump housing that stops conveying, Sealing must be set.In the prior art, generally all adopt end face seal, the gap sealing of rotation pump shaft and housing is converted into rotation rotating ring of himself and the sealing between the stationary ring end face, and it is few that this end face seal has leakage rate, advantages such as automatic compensation, but because mechanical sealing element all is to adopt the parts packing, the Installation and Debugging complexity, difficulty is big, and reliability is difficult to again guarantee, especially when other parts damages needed repairing, dismounting was very difficult.The patent No. is " 0220828.8 ", " being used in the integrated mechanical sealing spare between revolution pump shaft and the pump case ", though its conventional mechanical sealing element is quick detachable, its sealability is difficult to guarantee.

Summary of the invention

The purpose of this utility model is at the defective of above-mentioned prior art and deficiency, for desulfur pump provides integrated mechanical sealing spare a kind of new varieties.

The technological scheme that the utility model adopted is: this desulfur pump integrated mechanical sealing spare comprises the end face seal that is made of rotating ring and stationary ring, the rotating ring system that described rotating ring and fixing with it rotating seat are formed is fixedly installed on the outer end of axle sleeve, stationary ring and press on the stationary ring system that throw-out collar, spring and the spring seat of stationary ring interior edge face form and be fixedly installed on the gland center; Between rotating ring and rotating seat and stationary ring and gland, O-ring seals is housed respectively; Throw-out collar 7 is the T font, and it is pushed mutually by the spring 13 that is installed in the spring seat 8; The spring seat interior edge face of stationary ring system is equipped with postive stop baffle; The gland that is installed with the stationary ring system is fixed on the pump housing from inside to outside.

The utility model rotating ring system is arranged on the outer end of axle sleeve, the stationary ring system is fixedlyed connected with gland, and fix with the pump housing from inside to outside by gland, greatly facilitate installation, debugging and the maintenance of main equipment like this, when mounting or dismounting, avoid pulling down the heavy pump housing simultaneously, improve installation precision, alleviated working strength.

Embodiment

Referring to accompanying drawing, this desulfur pump integrated mechanical sealing spare is by constituting end face seal between rotating ring 2 and the stationary ring 4.Rotating ring 2 is fixed on the outer wall of rotating seat 1, on the surface of contact mutually O-ring seals 3 is housed, rotating seat 1 is installed on the outer end of axle sleeve 10, and rotating seat and pump shaft are fixed by bearing pin, make the axle sleeve outer end of pump shaft form the unsteady rotating ring system of forming by rotating ring 2, rotating seat 1 and O-ring seals 3.Stationary ring 4 is arranged on the exterior edge face, center of gland 12, between it and the gland O-ring seals 5 is housed.Bottom at stationary ring 4 is compressed mutually by throw-out collar 7, this throw-out collar 7 is the T font, and it is pushed mutually by the spring 13 that is installed in the spring seat 8, and postive stop baffle 9 is equipped with in spring seat 8 bottoms, one end of baffle plate 9 is entrenched in the perisporium groove of axle sleeve, and by screw postive stop baffle 9 and spring seat 8 is fixed.Driving pin 6 is fixed in the spring seat 8, and its head inserts the groove of stationary ring 4 bottoms, to prevent owing to relative to friction stationary ring being rotated with rotating ring.Like this, make the interior edge face of rotating ring 2 form the unsteady stationary ring system of forming by stationary ring 4, O-ring seals 5, driving pin 6, throw-out collar 7, spring seat 8, spring 13.Gland 12 and the pump housing 14 usefulness tight a bolt and 15 fix.Axle sleeve 10 fixes with pump shaft by positioning ring 16 usefulness set screws 11.Pull down postive stop baffle 9, desulfur pump running, the pump shaft rotation drives rotating ring and rotates synchronously, makes that the end face of stationary ring 4 and rotating ring 2 is relative to rotate friction, thereby reaches the purpose of sealing.
