Abstract
The invention relates to a high-strength heatproof heat-proof impeller. The impeller comprises the following raw materials by mass: 20 to 25% of Cr, 5 to 10% of Mn, 0.5 to 2.5% of N, 10 to 15% of C, 2 to 3% of Ni, 2 to 3% of Si and 0.5 to 0.9% of S, with the balance being Fe. The high-strength heatproof heat-proof impeller disclosed in the invention is prepared by mixing a plurality of materials and has the advantages of light total weight, high strength, capacity of meeting demands of a water pump on the impeller, and long service life.
Description
Technical field
The present invention relates to the component of pump, be specifically related to a kind of high strength heat resistant impeller.
Background technology
Impeller refers to the wheel disc that movable vane is housed, and finger wheel dish and the general name of rotating vane be installed on it, be the important component part of pump again.Because the environment for use of pump is different, the various performance requriementss for impeller are also not quite similar.Impeller of the prior art is many to be made up of metallic substance, and its weight strengthens, but intensity is less, is difficult to the need of work meeting pump.
Summary of the invention
For solving the technical problem existed in prior art, the invention provides high, the lightweight impeller of a kind of intensity.
Technique effect of the present invention is achieved through the following technical solutions:
A kind of high strength heat resistant impeller, its raw material according to the formation of mass percent is: Cr:20-25, Mn:5-10, N:0.5-2.5, C:10-15, Ni:2-3, Si:2-3, S:0.5-0.9, and surplus is Fe.
Further, its raw material according to the formation of mass percent is: Cr:20, Mn:5, N:2.5, C:10, Ni:3, Si:3, S:0.9, and surplus is Fe.
The invention has the beneficial effects as follows:
High strength heat resistant impeller disclosed in this invention, adopt novel high-strength heat-stable material to make, its oeverall quality is light, and intensity is high, good heat resistance, has stronger erosion resistance simultaneously, can meet the demand of pump to impeller, long service life.
Embodiment
Introduce technical solution of the present invention in detail below.
A kind of high strength heat resistant impeller, its raw material according to the formation of mass percent is: Cr:20, Mn:5, N:2.5, C:10, Ni:3, Si:3, S:0.9, and surplus is Fe.
Last it is noted that the foregoing is only the preferred embodiments of the present invention, be not limited to the present invention, although with reference to previous embodiment to invention has been detailed description, for a person skilled in the art, it still can be modified to the technical scheme described in foregoing embodiments, or carries out equivalent replacement to wherein portion of techniques feature.Within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
