Technical field
The utility model relates to a kind of wear resistant coating structure, particularly relates to a kind of silicon carbide wear resistant coating structure for Pulp pump, belongs to high-abrasive material technical field.
Background technique
Wearing and tearing are one of principal modes of mechanical parts inefficacy.Low stress erosive wear wherein be extensively present in especially modern industry produce machinery and system in, as component such as flow passage components, pipeline and the valves in mortar pump, slurry pump and Pulp pump that the industry such as mine, power plant uses, not only to bear erosion and the grinding of solid particle in the course of the work, also to bear the abrasion of liquid medium and the effect of high temperature, working environment is extremely severe, cause these parts wears serious, working life is shorter.For this reason, will there is the rich chromium cast iron of higher hardness and abrasion resistance as the material manufacturing Pulp pump, and achieve certain effect.But along with the increase of actual production and the maximization of Pulp pump, the transporting velocity of liquid slurry increases, rich chromium cast iron is difficult to resist the abrasion and cavitation erosion that the erosive wear of high-speed solid particle and liquid medium cause, the Pulp pump serious wear causing rich chromium cast iron to be made.
Stupalith has higher hardness and good wear-corrosion resistance, metal composite good to itself and processability, toughness and intensity is formed composite surface material, both bi-material performance separately can have been given full play to, again can for the design carrying out material property and structure under different working condition artificially, with the requirement to component under satisfied different operating mode.But due to stupalith preparation, processing difficulties, cost of production is high, and fragility is large, makes it apply and receives larger restriction.
Summary of the invention
The purpose of this utility model is not wear-resistant for the parts that operating mode in existing Pulp pump is poor and corrosion, the poor adhesive force of metal surface is not easy to arrange wearing layer, the defect that working life is shorter and deficiency, there is provided a kind of wearing layer bonding state good, shock resistance and fatigue ruption, there is well wear-resisting and decay resistance, be convenient to machine shaping, a kind of silicon carbide wear resistant coating structure for Pulp pump of long service life.
For achieving the above object, technical solution of the present utility model is: a kind of silicon carbide wear resistant coating structure for Pulp pump, comprise metal basal plane, the outer surface of described metal basal plane evenly offers crisscross fixing notch, in fixing notch, correspondence is fixed with embedded with support, carrier unit crisscross on embedded with support defines multiple coating and separates, and the outer surface of metal basal plane is provided with resin bottom, and the upper surface of resin bottom and the outer surface of embedded with support are equipped with wearing layer.
The inside spaced set of described wearing layer has Coated Steels wire ring, and Coated Steels wire ring and embedded with support are fixedly connected.
Described wearing layer adopts vinyl ester resin, silicon-carbide particle and coupling agent to make.
The height that described embedded with support is positioned at metal basal plane outer surface is less than the thickness sum of resin bottom and wearing layer.
The thickness of described resin bottom is 0.2 millimeter-3 millimeters, and the thickness of wearing layer is 2 millimeters-12 millimeters.
The beneficial effects of the utility model are:
1, the utility model evenly offers fixing notch at the outer surface of metal basal plane, in fixing notch, correspondence is fixed with embedded with support, the resin bottom that embedded with support can be laid outside and wearing layer play the effect that well dispersion is fixing, improve the adhesion property of metal basal plane outer surface.
2, the utility model is rational in infrastructure, there is well wear-resisting and decay resistance, effectively prevent wearing layer and occur phenomenon that is loosening or local bursting crack because the adhesion between metal basal plane is not enough, its bonding state is good, flawless, the fatigue ruption that Absorbable rod solid particle repeated stock cladding material surface causes, long service life.

Embodiment
Illustrate below in conjunction with accompanying drawing and with embodiment, the utility model to be described in further detail.
See Fig. 1 to Fig. 3, a kind of silicon carbide wear resistant coating structure for Pulp pump of the present utility model, comprise metal basal plane 1, it is characterized in that: the outer surface of described metal basal plane 1 evenly offers crisscross fixing notch 2, in fixing notch 2, correspondence is fixed with embedded with support 3, carrier unit crisscross on embedded with support 3 defines multiple coating and separates 4, the outer surface of metal basal plane 1 is provided with resin bottom 5, and the upper surface of resin bottom 5 and the outer surface of embedded with support 3 are equipped with wearing layer 6.
The inside spaced set of described wearing layer 6 has Coated Steels wire ring 7, and Coated Steels wire ring 7 and embedded with support 3 are fixedly connected.
Described wearing layer 6 adopts vinyl ester resin, silicon-carbide particle and coupling agent to make.
The height that described embedded with support 3 is positioned at metal basal plane 1 outer surface is less than the thickness sum of resin bottom 5 and wearing layer 6.
The thickness of described resin bottom 5 is 0.2 millimeter-3 millimeters, and the thickness of wearing layer 6 is 2 millimeters-12 millimeters.
See Fig. 1, there are the component such as the flow passage components of the poor equipment of more working condition, pipeline and valve in Pulp pump, the utility model arranges wear resistant coating structure on the poor outer surface metal basal plane 1 of working condition, to improve the performance of the wear-resisting and resistance to chemical attack of parts surface.The outer surface adhesive quality of conventional metals basal plane 1 is poor, be unfavorable for arranging wear resistant coating, the utility model evenly offers crisscross fixing notch 2 at the outer surface of metal basal plane 1, in fixing notch 2, correspondence is fixed with embedded with support 3, embedded with support 3 is interlocked by the carrier unit of transverse distribution and the carrier unit of genesis analysis and forms, the resin bottom 5 can laid outside after embedded with support 3 embeds and is fixed on the outer surface of metal basal plane 1 and wearing layer 6 play the effect that well dispersion is fixing, improve the adhesion property of metal basal plane 1 outer surface.
