Abstract
A sealing ring between a large-scale mud pump shaft sleeve and a pump body comprises a metal skeleton and a hub-shaped rubber part enveloped outside the metal skeleton, wherein the sealing ring adopts axisymmetric and split component combination structure, and the integrated combination of the axisymmetric components can be realized by means of a dovetail groove structure arranged on the split end surface of the metal skeleton. Therefore, the large-scale mud pump and other parts are avoided to be dismantled during maintenance process, thus greatly improving the overhauling efficiency and maintenance efficiency.
Description
Technical field
The utility model relates to a kind of seal ring, the seal ring between the specifically a kind of large-scale slurry pump axle sleeve and the pump housing.
Background technique
The volume of large-scale slurry pump is very huge, and single pump Beijing South Maxpower Technology Co. Ltd reaches 120 tons.The medium that slurry pump is carried is the thick substances of mobile difference such as mud, sandstone, and these materials are to the damage that the pump housing washes away for a long time, grinding can cause the pump housing and structure member thereof, and therefore, the sealing of slurry pump seems extremely important.Slurry pump axle sleeve at work runs up, and seal ring is very easy to be worn, and adds the working environment of slurry pump strong motion and washing away of fed sheet of a media, also is very easy to cause the damage of seal ring.What traditional slurry pump axle sleeve and the seal ring of the pump housing adopted is integral structure, also needs other parts of dismounting slurry pump earlier in maintenance and the process opened and inspect, for large-scale slurry pump, and maintenance operation complexity and inefficiency like this.
The model utility content
At above defective, the utility model provides the seal ring between the large-scale preferably slurry pump axle sleeve of a kind of convenient disassembly, sealing effect and the pump housing.
Seal ring between this large-scale slurry pump axle sleeve and the pump housing by metal frame and envelope the rubber parts on metal frame form, metal frame is that the cross section is the annulus of rectangle, rubber parts is hub-like, seal ring is an axisymmetric opposite opened component combined structure, splits the integrated combination of the oat tail groove structure realization axisymmetric parts on the end face by means of being arranged on metal frame.
The outer rim of metal frame protrudes from the surface of rubber parts, is used to locate seal ring; Splitting of rubber parts has one deck sealed binder between the end face.
Rubber parts adopts the elastic caoutchouc of wear-resisting type to make, and still can keep good sealing effect in the very big workplace of vibrations; Only need during installation dovetail groove on the metal frame of two opposite opened semicircles and dovetail tangs butt joint, and adhesive rubber get final product, this structure can avoid dismantling other component of large-scale slurry pump, greatly the raising efficient of opening and inspecting, keeping in repair.
Description of drawings
Fig. 1 is the plan view of the semicircle of seal ring between the large-scale slurry pump axle sleeve and the pump housing;
Fig. 2 is that the A of Fig. 1 is to view;
Fig. 3 is the B of Fig. 1---the B sectional view.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
Referring to Fig. 1 and Fig. 2, the utility model by metal frame 3 and envelope the rubber parts 4 outside metal frame 3 form, metal frame 3 is that the cross section is the annulus of rectangle, rubber parts 4 is hub-like, seal ring is an axisymmetric opposite opened component combined structure, split the integrated combination of the oat tail groove structure realization axisymmetric parts on the end face by means of being arranged on metal frame, its oat tail groove structure is made up of dovetail groove 1 and dovetail tangs 2.Splitting of rubber parts 4 has one deck sealed binder between the end face.
The outer rim of metal frame 3 protrudes from the surface of rubber parts 3; Rubber parts 4 is provided with two circle outer edge bulge 7,8, and its cross section is a rectangle, and along metal frame 3 symmetries. semicircle technology pit 5,6. is set on the rubber parts above dovetail groove 1 and the dovetail tangs 2
Referring to Fig. 3, the cross section of the circle of two on metal frame 3 and two rubber parts 4 outer edge bulge 7,8 is the cross type, and this cross is the supporting frame of seal ring, and other device of black box is provided with and the corresponding mounting groove of supporting frame.Rubber parts adopts the wear-resisting type elastic caoutchouc to make, and still can keep good sealing effect in the very big occasion of vibrations.
Only need during installation the dovetail groove on the metal frame of two opposite opened semicircles and dovetail tangs docked from top to bottom and press tightly, and adhesive rubber gets final product.This structure can avoid dismantling other component of large-scale slurry pump, improves the efficient of opening and inspecting, keeping in repair greatly.
