Description

A kind of novel adjustment half-and-half type stripping ring

Technical field

The utility model relates to centrifugal type slurry pump field, particularly a kind of novel adjustment half-and-half type stripping ring for centrifugal type slurry pump.

Background technique

Pulp pump is used to carry containing the flowing medium of solid particle, i.e. slag slurry, a kind of equipment, it is widely used in multiple industries such as chemical industry, coal, metallurgy, electric power, mining production, and may be used for blowdown and irrigate, and purposes is very extensive.Pulp pump adopts centrifugal structure usually.

Connection in the rotor structure of Pulp pump between its pump shaft and impeller adopts threaded connection design, and make the hand of spiral of impeller contrary with the sense of rotation of pump, add location and the locking effect of axle sleeve, coordinating after making Pulp pump operation between impeller with pump shaft is more and more fastening, thus plays the effect preventing impeller from coming off.But the impeller due to Pulp pump is flow passage components, very easily wear and tear, replacement frequency is high, and between pump shaft with impeller, coordinate this factor of tension, create on the contrary and dismantle the very difficult defect of impeller from pump shaft, when needing after damage in impeller to change, need to expend a lot of manpowers, very high labor intensity, and the probability causing pump shaft to damage in unloading process is high.In order to carry out centering adjustment to impeller and facilitate the dismounting of impeller, usually arrange and regulate stripping ring 1.

Existing stripping ring has various structures, three-clove style stripping ring 2 ' such as shown in Fig. 1, three-clove style stripping ring 2 ' is arranged on the live axle between bearing housing and impeller, is the dismounting being realized stripping ring by three pieces of identical dismounting blocks by adjacent side Bolt Connection, and then dismantles impeller again.Three-clove style stripping ring 2 ' can be used for realizing the dismounting to impeller, but still bearing housing need be adopted to regulate the position of impeller centering.In addition, three-clove style stripping ring is with bolts, installs inconvenience on the one hand, reduces efficiency; On the other hand, along with the prolongation of time, bolt easily becomes rusty extremely, brings difficulty, also just make troubles to maintenance like this to stripping ring dismounting itself.In addition, its structure of three-clove style stripping ring itself also more complicated.Adopt bearing housing to regulate the centering position of impeller to make the structure of system become complicated, be with moving axis and associated components to move integrally by tightening with loosering a bolt, and then play the object regulating impeller location, operation effort is inconvenient; The existence of bearing housing in addition, makes the bearing size of installation reduce, and the bearing capacity of bearing reduces, and affects the working life of whole system.

Fig. 2 shows the structure of existing half-and-half type stripping ring, and it comprises the semicircular ring 2 of two symmetrical configuration.Half-and-half type regulates the plurality of specifications of stripping ring 2 different-thickness, just can regulate impeller centering position and take off stripping ring by different thickness, and namely detachable impeller, therefore, does not need bearing housing to regulate the centering position of impeller, simplify the structure of stripping ring.But, if two of half-and-half type stripping ring semicircular ring variable thickness cause, card will be caused not dead, easily semi-ring is got rid of, reduce safety reliability; When regulating impeller neutral position in addition, the stripping ring of different-thickness, owing to can not form an entirety, all first will stamp jump ring at every turn, will take off jump ring again, then adjust suitable thickness if improper, again repeated removal and installation jump ring, operation and inconvenience.That is, when overhauling Pulp pump at the scene, not being often whole disintegration, is site examining and repairing mostly, at this moment half-and-half type stripping ring is not first fix to get on from one end assembling of main shaft with steel wire clip again, but first stripping ring is installed on axle, and then fixing steel wire clip, because operating space is limited, while need two of stripping ring each and every one semicircles good, also to steel wire clip be assembled on stripping ring on one side, extremely require great effort, very inconvenient.

Summary of the invention

In view of this, the utility model provide a kind of at the scene overhaul Pulp pump time easy to assembly, be convenient to locate docking novel adjustment half-and-half type stripping ring.

The utility model provides a kind of novel adjustment half-and-half type stripping ring, comprises the semicircular ring 2 of two symmetrical configuration, it is characterized in that: the interface of two semicircular ring 2 is provided with positioning means.

Described positioning means comprises the depressed part 1 being positioned at first annulus and the protuberance 3 being positioned at second annulus.

Described depressed part 1 is mutually corresponding with the position of described protuberance 3.

Width and the length of described depressed part 1 and described protuberance 3 are mated mutually, and make when two semicircular ring 2 are docked, described protuberance 3 extend into the inside of depressed part 1.

The outer peripheral surface of described stripping ring is provided with the groove around excircle.

Described groove is positioned on the center line of the excircle of stripping ring.

Groove is used for winding steel wire clip 4, makes two semicircular ring 2 can form a complete stripping ring.

Novel adjustment half-and-half type stripping ring structure of the present utility model is simple, two semicircular ring are easy to location docking, thus it is convenient for assembly when overhauling at the scene, there will not be dislocation, in manufacture and storage, can not confusion get wrong in transportation process, when can ensure to install, two halves ring thickness is identical, is combined into one easy location and installation, is convenient to dismounting, and can ensure that in work running, unlikely getting rid of causes the accident.Regulate moderate after stamp steel wire clip again, be convenient to the replacing of different-thickness stripping ring.
