Abstract
A blade with high toughness for submersed pump contains C (2.1-3.6 wt %), Si (0.9), Mn (1.1-1.5), P (0.03), S (0.03), Cr (12-17), Mo (0-2.0), rare alloy (0-2.5) for playing the desulfurizing and deaerating role, and Fe (rest).
Description
Technical field
The present invention relates to a kind of submersible pump blade.
Background technique
The present submersible pump blade that uses, because the working environment of above-mentioned machinery is very abominable, blade is subjected to resistance big again in addition, the most easy to wear or the fracture of blade, working life is shorter, needs frequently to change, and normally used submersible pump blade, its wear resistance and toughness are obviously not enough.
Summary of the invention
The purpose of this invention is to provide a kind of wear resistance and good toughness, long service life, low, the simple submersible pump blade of preparation process of cost of production.
The object of the present invention is achieved like this, the weight percentage of this leaf chemical ingredient is C2.1-3.6, Si0.9, Mn1.1-1.5, P0.03, S0.03, Cr12-17, Mo smaller or equal to 2.0, rare alloy smaller or equal to 2.5, all the other are iron.
The present invention compared with prior art adds rare alloy in the leaf chemical ingredient, play the effect that desulfurization is degassed, and can improve the toughness of submersible pump blade significantly, thereby can reduce the use amount of noble metals such as chromium, reduces production costs.
Description of drawings
The present invention does not have accompanying drawing
Embodiment
The weight percentage of embodiment's 1 this submersible pump leaf chemical ingredient is that C2.1, Si0.9, Mn1.1, P0.03, S0.03, Cr12, Mo equal 0.1, rare alloy equals 2.5, all the other are iron.The submersible pump vanes experiment of producing is than the life-saving 20% that uses now.
The weight percentage of embodiment's 2 these submersible pump leaf chemical ingredients is that C2.8, Si0.9, Mn1.3, P0.03, S0.03, Cr14.5, Mo equal 1.25, rare alloy equals 1.25, all the other are iron.The submersible pump vanes experiment of producing is than the life-saving 20% that uses now.
The weight percentage of embodiment's 3 these submersible pump leaf chemical ingredients is that C3.6, Si0.9, Mn1.5, P0.03, S0.03, Cr17, Mo equal 2.0, rare alloy etc. 2.5, all the other are iron.The submersible pump vanes experiment of producing is than the same life-saving 20% that uses now.
