Abstract
The utility model discloses a ceramic plunger piston which comprises a metal handle and a plunger piston body arranged on the metal handle. The plunger body is a ceramic plunger piston body, the metal handle is connected with the plunger piston body through a thread, and an adhesive layer is arranged between the metal handle and the plunger piston body. Because the metal handle is connected with the plunger piston body by adopting the thread, the connection of the plunger piston and the metal handle is firm without easily shedding, adhesive is filled between the plunger piston body and the metal handle so as to prevent the thread from loosing, the contact surface and the working surface of the plunger piston body and medium are both structural ceramics, and the metal handle and the plunger piston body adopt the thread connection and the adhesive is filled between the plunger piston body and the metal handle. The utility model has the advantages of shedding prevention, reliable connection and high strength, thereby prolonging the service life of the ceramic plunger piston. The ceramic plunger piston is over 2 times more than the common ceramic plunger piston for the service life, can prolong the service life of sealing filling, and has the advantages of very high abrasion resistance, corrosion resistance and impact prevention.
Description
Technical field
The utility model relates to the pump ceramic plunger that use workplaces such as industries such as a kind of oil, chemical industry are wear-resistant, corrosion-resistant, high temperature resistant.
Background technique
At present in industries such as oil, chemical industry, the application of ceramic plunger is constantly expanded, the use of ceramic plunger has wear-resisting, corrosion resistant advantage, but used ceramic plunger all is directly to adorn the ceramics pole cock body outside metal handle now, plunger body and metalwork joint are loosening easily, it is unreliable to connect, and comes off easily, thereby influences life-span of ceramic plunger.
Summary of the invention
The purpose of this utility model just is to provide a kind of ceramic plunger of the long service life that is connected firmly.
The purpose of this utility model can realize by following measure:
A kind of ceramic plunger, it comprises metal handle and is contained in plunger body on the metal handle, and plunger body is the ceramics pole cock body, and metal handle is to be threaded with plunger body.
Above-mentioned ceramic plunger is provided with adhesive layer between metal handle and plunger body.
Above-mentioned ceramic plunger, described ceramics pole cock body are that Zirconia reinforced alumina material or pure zirconia material are made.
Above-mentioned ceramic plunger is equipped with through hole ceramics pole cock body outside metal handle, in the metal handle end tightening nut is housed.
Above-mentioned ceramic plunger, described ceramics pole cock body are blind hole ceramics pole cock bodys.
The utility model is threaded owing to metal handle adopts with plunger body, plunger body and the metal handle difficult drop-off that is connected firmly, fill adhesive between plunger body and the metal handle simultaneously, prevent thread looseness, be structural ceramics with medium surface of contact and working surface, metal handle adopts to be threaded with plunger body fills adhesive between while plunger body and the metal handle, such structure has Drop-proof, connect reliable, advantages of high strength, thereby prolonged the working life of ceramic plunger greatly, the utility model is than the high life of conventional ceramic plunger more than 2 times, blind hole ceramics pole cock body in use simultaneously, what directly contact with stuffing box packing is whole potteries, therefore can improve the stuffing box packing life-span, have high wear-resistant, anticorrosive, shock proof advantage.
Below table 1 be the performance table of conventional ceramic and Zirconia reinforced alumina ceramic, zirconia ceramics
Description of drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is the utility model preferred structure schematic representation.
