Abstract
The invention provides a wear-resistant pump body for a vane type pump, and the pump body is easy to be shaped according to the requirements of hydromechanics, thereby being conductive to improving the efficiency of the pump and having better wear resistance. The technical scheme of the invention is as follows: the pump body adopts a composite wear-resistant material containing 10-98% (by weight) of abrasive particles and 2-90% (by weight) of resin binding agent, at least one framework is arranged on the pump body, one end of the framework is combined with the composite wear-resistant material together, and the end surface at the other end is vertical to the shaft line of a pump shaft.
Description
Affiliated technical field
The present invention relates to a kind of vane type oil pump pump housing, the wear-resisting pump housing of vane type oil pump of the solid-liquid two-phase flow of abrasion is arranged in particular for conveying.
Background technique
When vane type oil pump had the abrasion solid-liquid two-phase flow in conveying, flow passage components easily were worn.Prior art is for addressing this problem, the normal wear-resistant materials such as abrasion resistance alloy or rubber that adopt are made flow passage components, but because the restriction of the process characteristic of made, the flow-passing surface of the wear pump pump housing is difficult to carry out appearance by hydromechanical requirement, and this situation can cause the efficient of pump to reduce.
Summary of the invention
For solving the above-mentioned deficiency of prior art, the invention provides the wear-resisting pump housing of a kind of vane type oil pump, this pump housing is easy on technology by hydromechanical requirement appearance, and wear-resisting property is preferably arranged.
The technical solution adopted for the present invention to solve the technical problems is: the material of the pump housing is the composite abrasion resistance material of the resin-bonded agent that contains the abrasive grain of 10-98% (weight) and 2-90% (weight); The pump housing is provided with at least one skeleton, and an end and the composite abrasion resistance material of skeleton combine, the vertical pump shaft axis of the end face of the other end; The pump housing is connected by other parts of skeleton and pump.
It is lower and wear resistance is artificial preferably or natural abrasive that above-mentioned abrasive grain is generally cost, as silicon nitride, silicon carbide, corundum, garnet, emery, zirconium oxide etc.Can adopt a kind of abrasive material wherein, also can adopt several abrasive material combinations to strengthen the wear resistance of composite abrasion resistance material simultaneously.If only the mechanical strength of the composite abrasion resistance material of being made up of abrasive grain and resin-bonded agent can not meet design requirement, can add the auxiliary material that are no more than 49% (weight) therein and improve mechanical strength, these auxiliary material have cellosilk, fleece, French chalk, coupling agent, plasticizing agent etc., add and fashionablely add wherein a kind ofly, also can add wherein several.
The invention has the beneficial effects as follows: because the composite abrasion resistance material of rational formula has formation technique and wear resistance preferably preferably, so the pump housing not only is easy to help improving the efficient of pump by hydromechanical requirement appearance, also can guarantee working life; Skeleton in that connection part is provided with can guarantee join strength and precision.
