Description
Technical Field
The utility model relates to a novel wear-resisting corrosion resistant ceramic plunger of structure specifically is a high strength ceramic plunger.
Background
Traditional metal plunger is perishable in acid-base environment, and the cladding material easily drops, causes the plunger to scrap, and the filler is sealed to be scrapped, and the leakage capacity increases suddenly, and corrosive medium way shop reaches drive end scheduling problem, and life is short.
The ceramic plunger belongs to structural ceramics, adopts the super-hard wear resistance of modern engineering ceramic materials, can be assembled and molded by utilizing ceramic metallization bonding, welding, embedding and sleeving technologies, has extremely high hardness, wear resistance, corrosion resistance, high pressure resistance and thermal shock resistance, solves the problems of short service life of equipment caused by poor wear resistance, poor corrosion resistance and poor working temperature resistance of the metal plunger, increases the yield for users, saves the cost, saves the maintenance cost, effectively reduces the operation times of shutdown and pump inspection, improves the service life, is 5-10 times of the service life of the metal plunger, is the most ideal substitute product of the metal plunger of the same kind, and is widely applied to industries of medical instruments, environmental engineering, petroleum, chemical engineering and the like at present. However, the ceramic plunger is easy to crack or burst under different working conditions, particularly under high-temperature and high-pressure conditions, and a general ceramic plunger structure is formed by bonding a metal core and a ceramic outer sleeve through ceramic glue and fastening and assembling through threads.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a high strength ceramic plunger to solve the problem that proposes among the above-mentioned background art.
In order to solve the technical problem, the utility model discloses a technical scheme is:
the utility model provides a high strength ceramic plunger, includes the metallic body, ceramic body, metal end cap, the metallic body is the steel core, the front end of metallic body is equipped with the screw hole with one heart, be equipped with on the metallic body and evenly mill a plurality of axial cross sections that follow its axial for sectorial fan-shaped recess, the front end of fan-shaped recess is in form the opening on the metallic body front end side, the ceramic body is sectorial strip ceramic block for the axial cross section, the ceramic body with fan-shaped recess closes, a plurality of fan-shaped recesses in all be equipped with the ceramic body, metal end cap threaded connection the screw hole, and compress tightly the front end of ceramic body.
Furthermore, a rubber gasket is arranged on the metal plug.
Furthermore, the ceramic bodies are all bonded in the fan-shaped grooves through ceramic glue.
Furthermore, the blank body after the metal body and the ceramic body are assembled into a matching body needs to be integrally rounded.
The utility model has the advantages that:
the utility model provides a high strength ceramic plunger, its simple structure, novelty, ceramic body hardness height, intensity height, wearability are good, the tissue is fine and close, and smooth finish is good, and the ceramic body piecemeal bonds with the metallic member, and connected mode is reliable, and physical mechanical properties is superior, can bear high temperature high pressure operating mode condition, is difficult for producing crackle and phenomenon of bursting.
