Abstract
The utility model relates to Sealing technical field, particularly relate to a kind of sealing ring for centrifugal pump, it comprises seal ring body, described seal ring body is made up of inner ring and outer ring, described inner ring is alloy steel ring, and described outer ring is stainless steel coil, described outer ring parcel inner ring, the inner ring of described seal ring body is formed by surfacing, and the thickness of inner ring is 1mm.Seal ring of the present utility model is wear-resistant and then decrease the frequency changing seal ring, also saves simultaneously and often changes the loaded down with trivial details of seal ring.
Description
Technical field
The utility model relates to Sealing technical field, particularly relates to a kind of sealing ring for centrifugal pump.
Background technique
Seal ring is one of comparatively crucial component of multistage centrifugal pump, be related to the efficiency of whole pump, its material can make Ordinary Steel or stainless steel, traditional seal ring is for simply to process, the initial normal operation of whole pump after installation, but along with the effect of the solid particle contained in mining water qualities, seal ring is worn very soon, time serious, wear extent reaches more than three or four millimeters, and serious likely kills, pump is caused normally to start, even burn out motor, seal clearance is expanded, flow and the efficiency of whole pump sharply decline.
Model utility content
The purpose of this utility model is to propose a kind of sealing ring for centrifugal pump, and sealing ring is wear-resistant and then decrease the frequency changing seal ring.
For reaching this object, the utility model by the following technical solutions:
A kind of sealing ring for centrifugal pump, comprise seal ring body, described seal ring body is made up of inner ring and outer ring, described inner ring is alloy steel ring, and described outer ring is stainless steel coil, described outer ring parcel inner ring, the inner ring of described seal ring body is formed by surfacing, and the thickness of inner ring is 1mm.。
Preferably, the inner circle wall that described seal ring body inner ring contacts with impeller is provided with the arc convex be evenly equipped with to projecting inward, and described arc convex is made up of magnetic material.
Preferably, described seal ring body outer ring is provided with connected unit in order to wear screw connection seal ring and impeller.
Preferably, described connected unit and seal ring body are integral type.The utility model beneficial effect:
On the inner circle wall that the utility model contacts with impeller at traditional seal ring, surfacing has alloy steel ring, and then can reduce ring wear, improves the utilization efficiency of seal ring, also saves simultaneously and often changes the loaded down with trivial details of seal ring; Arc convex is made up of magnetic material, and making between seal ring and axle can closely adhesive, and sealing effect is better.
Accompanying drawing explanation
Fig. 1 is the structural representation of the sealing ring for centrifugal pump that the utility model embodiment provides;
The sectional view of the sealing ring for centrifugal pump that Tu2Shi the utility model collective mode of execution provides.
In figure:
1, seal ring body; 2, inner ring; 3, outer ring; 4, arc convex; 5, connected unit.
Embodiment
The technical solution of the utility model is further illustrated by embodiment below in conjunction with accompanying drawing.
The utility model provides a kind of sealing ring for centrifugal pump, it comprises seal ring body 1, it is characterized in that: described seal ring body 1 is made up of inner ring 2 and outer ring 3, described inner ring 2 is alloy steel ring, and described outer ring 3 is stainless steel coil 3, and inner ring 2 is wrapped up in described outer ring 3, inner ring 2 surfacing is on the inner circle wall of outer ring 3 in the fabrication process, and the thickness of inner ring is 1mm, described spray material is Ni-based, can ensure that inner ring thickness evenly and save material like this.
In present embodiment, certain friction can be there is between seal ring body 1 and impeller, the meeting rubbing serious produces gap, the inner circle wall that described seal ring body 1 inner ring 2 contacts with impeller is for this reason provided with the arc convex 4 be evenly equipped with to projecting inward, described arc convex is made up of magnetic material, and magnetic material can make seal ring body 1 pair of impeller attach.
In order to make seal ring body 1 be connected fastening with the impeller of centrifugal pump, described seal ring body 1 outer ring 3 is provided with connected unit 5 and connects seal ring and impeller in order to wear screw.
In present embodiment, preferably, described connected unit 5 seal ring body 1 is integral type.
More than show and describe basic principle of the present utility model and major character and advantage of the present utility model.The technician of the industry should understand; the utility model is not by the restriction of above-mentioned mode of execution; what describe in above-mentioned mode of execution and specification just illustrates principle of the present utility model; under the prerequisite not departing from the utility model spirit and scope; the utility model also has various changes and modifications; these changes and improvements all fall within the scope of claimed the utility model, and claimed scope of the present utility model is defined by appending claims and equivalent thereof.
