Abstract
The utility model relates to a ceramic pump flow passage component which is composed of a ceramic layer, an adhesive layer and a casing layer. The utility model is characterized in that: the ceramic layer is sintered and formed by ceramic material; the adhesive layer is arranged between and bonds the casing layer and the ceramic layer; the average thickness of the adhesive layer is between 0. 3 mm and 30 mm. The ceramic pump composed of the flow passage components can transfer corrosive fluid containing relatively big solid particles, and the utility model can also be used for the occasions with strong vibration during operation.
Description
The utility model is relevant with the improvement of ceramicpump.
Pottery have than metal superior the wear-resisting property of Duoing, have extraordinary decay resistance simultaneously, so make the application of ceramicpump of flow passage part with pottery comparatively extensive.But pottery also has a significant disadvantages, is exactly generally more crisp, and is not shock-resistant.So at present ceramicpump generally can not be used for the fluid that pumping contains big solid particle, can not be used for to produce the occasion of judder simultaneously, because ceramic flow passage part is subject to greater impact and destroys and make the pump ability of losing the job under these operating modes.Application number 94108074.9 discloses a kind of sheath and manufacture method, it is characterized in that Si
3N
4Ceramic plate is bonded on the rubber layer with binder, rubber layer is bonded on the cast iron housing again, and this technology can solve the not impact-resistant problem of pottery effectively, but this technology construction is complicated, the manufacture cost height, and weak spot appears easily in making, flow passage part is easily from weak spot early failue.So can't apply in practice.
The purpose of this utility model is to provide a kind of can anti-greater impact also can carry the ceramicpump flow passage part that contains big solid particle fluid.
The utility model thes contents are as follows: the ceramicpump flow passage part is made up of ceramic layer, adhesives layer and shell layer, ceramic layer is by the stupalith thermal sintering, have adhesives layer that both are bonded together between shell layer and ceramic layer, the average thickness of adhesives layer is between 0.3-30mm.
Relative application number 94108074.9, the thickness that obvious characteristics of the utility model is an adhesives layer obviously increases, in application number 94108074.9 disclosed technology, the average thickness of adhesive layer generally can not surpass 0.3mm, causes that easily ceramic block comes off because thickness of adhibited layer surpasses this scope; And the average thickness of the utility model adhesives layer should help absorbing the impact that flow passage part in service is subjected to like this greater than 0.3mm; Relative application number 94108074.9 another obvious characteristics of the utility model are not have rubber layer, so flow passage part has rigidity preferably, and the ceramic block difficult drop-off.The utility model is owing to bond together ceramic layer and shell layer, so the impact that ceramic layer is subjected in installation and operation can be passed on the shell layer by adhesives layer, the shock-resistant ability of flow passage part is improved greatly, even if when operation ceramic layer be subjected to greater impact and localized cracks or breakage occur, because the support and the sealing of adhesives layer and shell layer, ceramic layer can not occur whole broken, fluid seepage can not occur under many circumstances yet, so pump still can continue operation.It is the diversity that stupalith is selected for use that the relative application number 94108074.9 of the utility model also has a feature, in the application number 94108074.9 owing to will consider the impact resistance of ceramic block, so ceramic block can only adopt the higher silicon nitride ceramics of cost, and the utility model is because the structure improvement, ceramic block can adopt potteries such as more cheap aluminium oxide, silicon carbide, can reduce manufacture cost greatly.So the ceramicpump with this flow passage part assembling can be carried the fluid that contains big solid particle, produce the occasion of judder in the time of also work can being used for.
Below in conjunction with embodiment and with reference to corresponding accompanying drawing the utility model is illustrated.
Fig. 1 is a structural drawing of the present utility model
As can be seen, ceramicpump flow passage part of the present utility model is made up of ceramic layer 1, outer shell layer 2 and adhesives layer 3 in the embodiment of accompanying drawing 1.Ceramic layer 1 is by engineering ceramics such as aluminium oxide ceramics thermal sintering among this figure embodiment, and binder 3 adopts resin, and outer shell layer 2 adopts the metal manufacturing.
In some embodiments, ceramic layer can sinter some into, and is bonded on the outer shell layer by binder.
When carrying some to contain the fluid of high hardness particle, can add some wear-resistant ceramic particles in the adhesives layer, like this when crackle appears in ceramic layer, binder in the adhesives layer can stop fluid seepage, ceramic particle wherein can be resisted in the liquid high speed of high hardness particle and wash away, and makes pump still can continue operation for a long time.
In some embodiments, outer shell layer and adhesives layer can adopt commaterial (as resin) manufacturing, like this can simplified manufacturing technique.
Because the utility model is implemented simple, so the professional and technical personnel can make various remodeling to above-mentioned ceramicpump flow passage part under the situation that does not exceed scope of the present utility model.
