Abstract
A wear-resistant centrifugal water pump impeller and a sealing ring matched with the same solve the problems of poor wear resistance and short service life of the impeller and the sealing ring which are made of a single material. The impeller sealing ring has the advantages that the mechanical property of the material is reasonably utilized, the abrasion resistance of the impeller and the sealing ring is improved, and the service life of the impeller sealing ring can be prolonged by 5-10 times.
Description
The utility model belongs to a kind of water pump accessory, particularly a kind of wear-resistant Centrifugal water pump impeller and associated seal ring.
The impeller of Centrifugal water pump and seal ring are a pair of components, impeller is installed on the rotatingshaft of water pump, seal ring is fixed on the dividing plate of water pump, leave 0.02～0.04 mm clearance between impeller and the seal ring, liquid refluxes to prime during with the prevention wheel rotation, realizes the sealing between the forward and backward level of water pump.Because the gap between impeller and the seal ring is very little, therefore, when the impeller high speed rotating, the matching part mutual friction mutually of impeller and seal ring, it is very fast to wear and tear; When the gap between impeller and the seal ring increased, the leakage of fluid increased, and the impeller end thrust increases, and caused pump efficiency to descend, until not running well; Impeller and seal ring are a pair of supporting use pump part, and its abrasion resistance properties should mate mutually, in case wearing and tearing are difficult to carry out repair.The impeller of Centrifugal water pump and seal ring are normally made with homogenous material in the prior art, adopt materials such as HT or QT as clean waterpump more, the slag stock pump adopts materials such as high-chromium alloy white iron (Cr15Mo3), high-chromium alloy cast steel more, and the abrasion resistance properties of HT and QT is poor, and working life is short; Though the abrasion resistance properties of high-chromium alloy white iron and high-chromium alloy cast steel is better than HT and QT, but still be difficult to satisfy usage requirement, and cost is also very high, make impeller and seal ring if adopt more the high-abrasive material of high hardness, then can be subjected to the restriction of machining, especially the keyway on the impeller, not only be difficult to processing, and, be difficult to the effect that reaches desirable, therefore, adopt single made water pump vane and seal ring, not only be difficult to satisfy usage requirement, and, mechanical property that can not the reasonable use material causes waste.
The purpose of this utility model is to overcome the deficiencies in the prior art part, change the conventional construction that water pump vane and seal ring use homogenous material to make, rationally utilize the mechanical property of different materials, a kind of wear-resistant Centrifugal water pump impeller and associated seal ring of rational in infrastructure, long service life is provided.
For achieving the above object, the utility model is wear-resistant, and the Centrifugal water pump impeller adopts common HT or QT casting impeller body, and its with position that water pump gland ring matches on surfacing one deck wear-resistant alloy layer, to strengthen its abrasion resistance properties.
In order to be used above-mentioned wear-resistant Centrifugal water pump impeller, the utility model also provides a kind of associated seal ring, it adopts common HT or QT casting seal ring body, and its with position that water pump vane matches on surfacing one deck wear-resistant alloy layer so that with the impeller use that matches.
Advantage of the present utility model is, impeller and seal ring adopt different materials to make, reasonable use the mechanical property of material, significantly improved the working life of impeller, impeller and seal ring as clean waterpump, behind position surfacing one deck wear-resistant alloy layer that it matches,, can improve 10 times working life though its cost has increased by 20%; The impeller of slag stock pump and seal ring, behind position surfacing one deck wear-resistant alloy layer that it matches, its cost can improve 5 times its working life than adopting high-chromium alloy white iron or high-chromium alloy cast steel to reduce by 70%.
Provide embodiment of the present utility model below in conjunction with accompanying drawing:
Fig. 1 is the structural representation of the utility model impeller;
Fig. 2 is the left view of Fig. 1;
Fig. 3 is the structural representation of the utility model seal ring;
Fig. 4 is the schematic representation that the utility model impeller matches with seal ring.
As shown in Figure 1 and Figure 2, the utility model is wear-resistant, and the Centrifugal water pump impeller has a common HT of usefulness or QT casting, and the impeller body 1 of process machining, surfacing has one deck wear-resistant alloy layer 2 on impeller body 1 and position that seal ring matches, wear-resistant alloy layer 2 is nickel-base alloy or ferrous alloy, can be selected according to its purposes; The section shape of wear-resistant alloy layer 2 is L shaped, and thickness is 0.5～3 millimeter.
As shown in Figure 3, the seal ring that the utility model and impeller match has a common HT of usefulness or QT casting, and the seal ring body 3 of process machining, surfacing has one deck wear-resistant alloy layer 4 on seal ring body 3 and position that impeller matches, wear-resistant alloy layer 4 is nickel-base alloy or ferrous alloy, can be selected according to its purposes; The thickness of wear-resistant alloy layer 2 is 0.5～3 millimeter.
As shown in Figure 4, during use, seal ring body 3 is fixed on the water pump dividing plate, impeller body 1 is installed on the water pump rotatingshaft, and its wear-resistant alloy layer 2 and wear-resistant alloy layer 4 are matched, the operation of can putting into production.
