Abstract
The utility model relates to an improved anticorrosion inner lining plastic pump which is characterized in that the inner side surface of a lining plastic pump body is uniformly processed with a plurality of blind holes or counter bores, and the lining plastic part of the lining plastic pump body is embedded into a shell body to form a riveted connection mode. Thus, the connecting adhesion of lining plastic and the pump body is enhanced, and the whole service life of the lining plastic pump is prolonged, so that the utility model is much suitable for being used at the state when temperature changes much.
Description
Model utility is about the improvement to the anti-corrosion plastic coating pump, relates in particular to the fastness that is connected that improves lining plastics and the pump housing.
People are for solving the anticorrosion problem of pump, and the effective way of a kind of less expensive is at metal pump case inner lining anti-rot plastic material.Yet because the thermal expansion coefficient of plastics and metal is inconsistent, in use owing to often running into reason such as expand with heat and contract with cold, plastic lining easily deforms and separates with the metal pump case, causes plastic lining and separating of pump case to cause coming off, and influences the working life of corrosion protection pump.Be the be connected fastness of raising plastic lining with metallic matrix, the someone proposes axially, radially to process the shallow ridges that angle is 60 degree at pump case, pump cover inwall, thereby reaches the adhesion that strengthens lining plastics and metal pump case, improves both connection fastness.But because pump housing cavity shape is comparatively complicated, inclined groove processing is difficulty comparatively, and be difficult for reaching at pump housing internal face and evenly distribute, cause the shallow ridges skewness easily, plastic lining is general mobile relatively poor in addition, and the inclined groove plastics are difficult for full full, especially ultra-high molecular weight polyethylene lining, thereby can not reach effective riveted joint effect, so whole connection attachment fastness is still not ideal enough, still having is worth improved place.
The purpose of model utility is to overcome the deficiency of above-mentioned prior art, and it is big to provide a kind of improved plastic lining and the pump housing to be connected attachment fastness, difficult drop-off, and the comparatively easy corrosion resistant plastic lined pump of processing and fabricating.
The model utility purpose realizes, the main improvement is to mould the inboard at the lining of the metal pump housing, be processed with blind hole or counterbore at interval, when moulding, the mold pressing lining melts by heat, the lining plastics are stretched in blind hole or the counterbore, be partially submerged into metal shell and form similar riveted joint thereby lining is moulded, reach and improve the lining plastics and be connected fastness, effectively prevented coming off of plastic lining with adhering to of pump case.Specifically, model utility corrosion resistant plastic lined pump comprises the metal pump housing and plastic lining, it is characterized in that said pump housing lining moulds the inboard and be distributed with numerous blind holes or counterbore, makes plastic lining be partially submerged into housing and forms riveted joint.
Further specify model utility and advantage below in conjunction with accompanying drawing.
Fig. 1 is the model utility organigram.
Fig. 2 is Figure 1A place magnifying show counter bore structure schematic representation.
Fig. 3 is Figure 1B place magnifying show blind hole structure schematic representation.
Embodiment: referring to accompanying drawing, alternate uniform blind hole or the counterbore 2 that is processed with hole plane approximate vertical of the metal pump case 1 overcurrent inner side surface of moulding at need linings, after the modified ultra-high molecular weight polyethylene filling, heating pressurization mold pressing forms the plastic lining layer 3 of 10-25mm.Not only make ultra-high molecular weight polyethylene attached to the pump housing and pump cover inwall, and, form similar riveted joint, be connected fastness with adhering to of the pump housing thereby strengthened the lined with ultra-high molecular weight polyethylene having blind hole or counterbore place ultra-high molecular weight polyethylene to embed wherein.
The model utility lining is moulded and is connected blind hole or counterbore, and also available ditch or groove replace; It can also be other engineering plastics or the like that lining is moulded.
Model utility is owing to mould face at plastic lined pump body lining and evenly be processed with and connect blind hole or counterbore, not only can improve the fastness that is connected of plastic lining and the pump housing, and easy processing, and the lining that is more suitable for the liner face and is shaped body is moulded.Straight hole not only is easy to processing, and is easier to the embedding of plastic lining, especially is fit to for example lining of ultra-high molecular weight polyethylene of mobile poor plastics.The model utility plastic lined pump is because plastic lining layer forms similar riveted joint at pump housing lining face, increased socketing of the lining plastics and the pump housing, effectively reduce the plastic lining amount of deformation, plastic layer is sticked on the pump case securely, make it more appropriate to serviceability temperature and change occasion greatly.The model utility mode also can be used for the lining of other objects and moulds.
