Abstract
The utility model relates to a roller pump for ceramic spray finishing, which is composed of a pump body, a pump cover, a rotor in the pump body, a roller in the pump body, etc., wherein a ceramic layer with a definite thickness is sprayed and painted on the end surface of the pump cover and the internal circular wall of the pump body respectively. The pump has the advantages of corrosion resistance, abrasion resistance, low cost, good service performance, etc.
Description
The utility model is a main workpiece on the atomizing sprayer, is mainly used in and sprays chemical pesticide in the agricultural production, also can be used for chemical industry, chemical fertilizer, papermaking, industries such as printing and dyeing.Belong to farm machinery.
Existing roller pump is by housing and rotor, compositions such as pump cover, and they all adopt cast iron materials.In use, cast iron materials is relatively poor to the corrosion resistance of liquid such as agricultural chemicals, and pump when running, owing to form fastness between pump housing rotor and pump cover, the pump housing, after using a period of time, pump cover end face and pump housing inner round wall surface abrasion, erosion are very serious, thereby the pressure of pump is descended, and influence is used.
At present, the method that adopts the integral material that changes pump is arranged both at home and abroad, prevent wearing and tearing and corrosion, as adopt nickeliferous foundry goods etc.Though can solve wearing and tearing and corrosion problem, cost is relatively more expensive, does not meet national conditions.
In order to address the above problem, the utility model sprays certain thickness ceramic layer on the pump housing surface that contacts with soup, and avoiding occurring wearing and tearing and the problem of corrosion, and cost is lower.
The utility model is achieved in that a kind of ceramic spraying roller pump, mainly is by the pump housing, pump cover, rotor in the pump housing and roller are formed, and it is characterized in that, increase thickness and be two kinds of variform ceramic fittings of 0.4～0.7 millimeter, be separately fixed on the inner round wall of the end face of pump cover and the pump housing.Further specify below in conjunction with accompanying drawing,
Fig. 1. the structural drawing of roller pump.
Fig. 2. be fixed with the pump cover figure of ceramic layer.
Fig. 3. be fixed with the pump housing figure of ceramic layer.
See Fig. 1, rotor (1), the pump housing (2), axle (3), back-up ring (4), bearing (5), twoport oil sealing (6), protecgulum (7), bonnet (8), " O " RunddichtringO (9), nameplate (10), ceramic layer (11).
The utility model is cast by the plain cast iron material, when work, soup mainly is contacted with pump protecgulum (7) end face, pump postoperculum (8) end face, and on the pump housing (2) inner round wall, therefore, (see figure 2) on the front and rear end of pump cover, and (see figure 3) on the pump housing inner round wall are with suitable thick aluminium oxide ceramics layer (11) material of 0.5MM that is fixed with of spraying shape, form ceramic on metal layer composite material, its ceramic thickness can be in 0.4～0.7MM scope.As less than 0.4MM, after spraying, then just do not have machining allowance, thereby can not guarantee desired degree of finish; As greater than 0.7MM, then Pen Tu pottery and the adhesion strength between the cast iron are not enough, easily come off, admittedly it is thick in best to spray 0.5MM.Its ceramic coated layer for the thick technical order of 0.5MM is:
After grinding machine processing, the ceramic layer surface finishment is 3.2
Coating and substrate combinating strength 1.1kg/mm
Microhardness of coating Hr716～920
The friction factor 0.11～0.13 of coating
Corrosion resistance is outstanding
Wear resistance is outstanding
By above-mentioned survey first finger mark as can be seen, the utility model not only conforms to usage requirement, but also has corrosion protection, and wear-resistant, cost is low, advantages such as long working life.
