Abstract
The utility model relates to a wear-resistant lining for a high-temperature concentrated sulfuric acid submerged pump, which is made of nodular cast iron. The utility model is characterized in that the inner surface of the lining is provided with a corrosion-resistant and wear-resistant layer formed by oxide ceramic, and the corrosion-resistant and wear-resistant layer formed by oxide ceramic can use the metal oxide material of Cr2O3. The lining provided by the utility model has the advantages of strong corrosion resistance, wear resistance, long service life, etc.
Description
The utility model relates to a kind of high-temperature concentrated sulfuric acid Under Water Pumps anti-wearing liner.
Adopt alloyed steel to make high-temperature concentrated sulfuric acid Under Water Pumps lining at present both at home and abroad mostly, its alloyed steel Main Ingredients and Appearance is Cr32, Ni29.5, Co10, Mo3, Cu3, Mn3, Si3-3.5 and other elements.Sleeve inner surface makes sleeve inner surface hardness reach RC45 through heat treatment, because Under Water Pumps when work axle sleeve contact friction with lining system surface, corrodes and weares and teares also from contact surface.Generally, when axle sleeve and each corrosive wear of lining fell that the gap surpasses 0.4mm between 0.2mm, axle sleeve and the lining, Under Water Pumps working stability performance just sharply descended.Above-mentioned alloyed steel lining exists cost height, the relatively poor problem of wear-resisting property.
The purpose of this utility model is to overcome the deficiency of above-mentioned prior art and a kind of high-temperature concentrated sulfuric acid Under Water Pumps anti-wearing liner is provided.
The utility model above-mentioned purpose is to realize like this.
A kind of high-temperature concentrated sulfuric acid Under Water Pumps anti-wearing liner is characterized in that said sleeve inner surface is provided with oxide ceramics anticorrosion antiwear layer.The lining two ends also can be provided with oxide ceramics anticorrosion antiwear layer.The lining matrix can adopt the spheroidal graphite cast iron manufacturing.
The utility model adopts spheroidal graphite cast iron to make matrix, and is provided with oxide ceramics anticorrosion antiwear layer at internal surface, helps reducing the lining cost, improves wear resistance and working life thereof, and then prolongs high-temperature concentrated sulfuric acid Under Water Pumps overall working life.
Introduce the utility model specific embodiment below in conjunction with accompanying drawing.
Fig. 1 is the utility model bush structure schematic representation.
In the present embodiment, Under Water Pumps lining 1 matrix adopting 45-2 spheroidal graphite cast iron is made moulding, then at lining 1 internal surface and the thick oxide ceramics anticorrosion antiwear layer 2 of two end part surfacing 0.2-0.5mm.Oxide ceramics anticorrosion antiwear layer 2 material that lining 1 adopts are Cr
2O
3, hardness is RC60.
