Description
Technical field
The utility model relates to a kind of pneumatic pump, particularly relates to a kind of pneumatic pump of ceramic structure.
Background technique
For the air pump of existing use, its material is generally metal, and the peak unit of metal parts sliding friction pair relative motion surface contacts with each other sometimes, under the effect of frictional force, produce plastic deformation.Now surperficial original adsorbed film, patina break, and fresh metal surface is exposed, make some peak unit of surface contact portion connect, namely produce the cold welding phenomenon in tribology under the effect of molecular force.Metal surface cold solder connection after cold welding is interconnected, and causes the increase of relative movement surface friction drag even can not relative movement, also causes tearing and producing chip of metal surface simultaneously.The evolution of cold welding is very rapid, can cause equipment major failures accident at short notice, once appear in the air pump of braking system, will cause gas leakage, during braking, pump gas is unable, braking force is not enough, has a strong impact on safety.
The gas pump structure of current research is all the piston, connecting rod, the crank structure that are similar to reciprocating internal combustion engine.The mounting process requirement of this structure not suitable ceramic pump housing.Explained hereafter that a kind of novel structure realizes the ceramic pump housing must be attempted carry out design and produce.
Model utility content
For above-mentioned technical problem, the technical solution that the utility model provides is a kind of ceramic structure pneumatic pump being easy to install and adapt to completely new process of design.
The utility model adopts following technological scheme to realize:
A kind of ceramic structure pneumatic pump, comprise the cylindrical shape pottery pump housing be made up of stupalith, front fixed support, rear fixed support, front cover, rear end cover, air pump piston, cover plate, described front fixed support, rear fixed support is provided with the cylinder assembly department that internal diameter and ceramicpump body diameter match, described front fixed support is stretched at the two ends of the described ceramic pump housing respectively, in the endoporus of rear support bracket fastened cylinder assembly department, and fixed by bonding mode, described rear end cover is connected by screw in rear fixed support rear end, described front cover and cover plate are connected to front fixed support front end in turn by screw, described air pump piston is arranged in the ceramic pump housing, match with ceramic pump housing inwall, the rod end of described air pump piston passes and extends to outside front cover and cover plate.
Further, the material of the described ceramic pump housing is zirconium oxide.
Further, described front fixed support, rear fixed support are provided with the stiffening rib for improving intensity.
Compared to existing technology, whole pump of the present utility model adopts split-type structural, because the ceramic pump housing is that cylindrical shape is easy to processing, and shape is comparatively complicated and don't relate to non-critical component affect usability and still adopt intermetallic composite coating, because adopting stupalith just can save oil lubrication, minimizing impurity is mixed into and reduces wear, thus improve the durable of air pump and reliability, improve the intensity of the pump housing, alleviate air pump weight, improve reliability and the Security of braking system.
The ceramic pump housing of this pneumatic pump and Steel Support select the mode of bonding connection, have weight reduction, simple to operate, save the advantages such as seal arrangement; And metallic member takes the mode of screw fastening, what assembling was become is relatively simple, and forward and backward support takes the design of stiffening rib, improves firmness degree.

Embodiment
Be described in further detail the purpose of this utility model below by specific embodiment, embodiment can not repeat one by one at this, but therefore mode of execution of the present utility model is not defined in following examples.
As shown in Figures 1 to 7, a kind of ceramic structure pneumatic pump, comprise the cylindrical shape pottery pump housing 5 be made up of stupalith, front fixed support 4, rear fixed support 6, front cover 3, rear end cover 7, air pump piston 7, cover plate 2, described front fixed support 4, rear fixed support 6 is provided with the cylinder assembly department 8 that internal diameter and the ceramic pump housing 5 external diameter match, described front fixed support 4 is stretched at the two ends of the described ceramic pump housing 5 respectively, in the endoporus of the cylinder assembly department of rear fixed support 6, and fixed by bonding mode, described rear end cover 7 is connected by screw in rear fixed support 6 rear end, described front cover 3 and cover plate 2 are connected to front fixed support 4 front end in turn by screw, described air pump piston 7 is arranged in the ceramic pump housing 5, match with the ceramic pump housing 5 inwall, the rod end of described air pump piston 7 passes and extends to outside front cover 3 and cover plate 2.
Specifically, described front fixed support 4, rear fixed support 6 are provided with the stiffening rib for improving intensity.
The material of the described ceramic pump housing 5 is zirconium oxide, and ceramic forming process is the important step of Machining of Ceramics process, the advantage such as high hardness, high strength of stupalith, gives the processing of pottery, being shaped brings difficulty.Desirable ceramic forming process, effectively to reduce body defect, control particle agglomeration, the ceramic equipment structure after shaping is even, has good compactness, the stupalith especially in extreme environment, for making its performance higher, also higher to the requirement of moulding process.
