Abstract
The utility model relates to a ceramic plunger which belongs to pump parts. A plunger body consists of a metal body, a metal choke plug and a wear-resistant ceramic sleeve; the wear-resistant ceramic sleeve is sleeved on the metal body; the metal choke plug and the metal body are connected by screws; and the wear-resistant ceramic sleeve is pressed and fixed by the metal choke plug. The ceramic plunger not only has the advantage of firm structure, but also has the advantages of good corrosion resistance and long service life.
Description
Technical field
The utility model relates to a kind of ceramic plunger, belongs to the pump base part.
Background technique
At present, the plunger pump that petroleum chemical industry uses mainly uses metal plunger, the general surface hardness that adopts treatment process such as steel surface surfacing nickel or chromium plating to improve the plunger working surface, the wear-resisting property of this plunger is better than customary quenching steel, but this corrosion-resistant, work under aggressive medium, working life is short.In order to solve this type of problem, also useful ceramic plunger replaces metal plunger, but at present structures that adopt ceramics pole and metal handle to bond together more, but in use, because bonding not firm, ceramics pole and metal handle come off easily, and the diameter of ceramics pole again can not be too big, it is just very difficult that diameter surpasses the above product sintering of 50mm, and therefore this method is just with the less plunger of production size.
The model utility content
The purpose of this utility model is to provide a kind of well-set ceramic plunger, good corrosion resistance, long service life.
Ceramic plunger described in the utility model, plunger body is arranged, and its plunger body is made up of metal body, metal plug and wear-resistant ceramic cover, and the wear-resistant ceramic cover is sleeved on the metal body, metal plug and metal body are by being threaded, and the metal plug is fixed the wear-resistant ceramic cover.
Be threaded owing to adopt, sound construction, the outer surface of metal body has wear-resistant ceramic cover, good corrosion resistance, long service life.
When plunger is big, metal body is designed to hollow structure, to alleviate the overall weight of plunger.
The equipped respectively buffering spacer in the two ends of wear-resistant ceramic cover as copper backing etc., eases off the pressure when assembling; can protect the wear-resistant ceramic cover effectively, prevent that wear-resistant ceramic cover is cracked, and in the process of using, can not come off or loosening; improve working life greatly, and simple in structure, is convenient to produce.
Be covered with binder between metal body and the wear-resistant ceramic cover, increase adhesive strength, that is to say, method bonding and that screw fit combines is adopted in assembling, with metal body outer surface and wear-resistant ceramic endoporus be worked into corresponding require size after, on the metal body outer surface, evenly smear the agent of one deck high strength bonding, then the wear-resistant ceramic cover is enclosed within on the metal body outer surface.
In like manner, be covered with screw thread glue on the connecting thread of metal plug and metal body, further strengthen the join strength of metal plug and metal body, that is to say that when implementing to connect, the place evenly is coated with last layer screw thread glue (market is on sale) with metal plug screw thread, and assemble with internal thread on the metal body, be seated, treat the Bond bone dry after, can carry out post-production.The utility model ceramic plunger is sound construction not only, and good corrosion resistance, long service life.
Description of drawings
Fig. 1, the utility model one example structure schematic representation.
Fig. 2, the utility model embodiment 2 structural representations.
Among the figure: 1, metal body 2, wear-resistant ceramic cover 3, binder 4, copper backing 5, metal plug 6, screw thread glue 7, metal body 8, wear-resistant ceramic cover 9, binder 10, hollow cavity 11, copper backing 12, metal plug 13, screw thread glue.
Embodiment
The utility model is described in further detail in conjunction with the foregoing description accompanying drawing.
As shown in Figure 1, ceramic plunger described in the utility model, plunger body is made up of metal body 1, metal plug 5 and wear-resistant ceramic cover 2, wear-resistant ceramic cover 2 is sleeved on the metal body 1, and metal plug 5 and metal body 1 are by being threaded, and metal plug 5 overlaps 2 with wear-resistant ceramic and is fixed, be covered with binder 3 between metal body 1 and the wear-resistant ceramic cover 2, the two ends of wear-resistant ceramic cover 2 are fitted with copper backing respectively, are used for buffering, are covered with screw thread glue 6 on the connecting thread of metal plug 5 and metal body 1.
As shown in Figure 2, ceramic plunger described in the utility model, plunger body is by metal body 7, metal plug 12 and wear-resistant ceramic cover 8 are formed, metal body 7 is designed to hollow structure, hollow cavity 10 is arranged, to alleviate the overall weight of plunger, wear-resistant ceramic cover 8 is sleeved on the metal body 7, metal plug 12 and metal body 7 are by being threaded, metal plug 12 is fixed wear-resistant ceramic cover 8, is covered with binder 9 between metal body 7 and the wear-resistant ceramic cover 8, and the two ends of wear-resistant ceramic cover 8 are fitted with copper backing 11 respectively, be used for buffering, be covered with screw thread glue 13 on the connecting thread of metal plug 12 and metal body 7.
Adopt screw thread and bonding dual mode, be connected firmly,, solved the corrosion resistance problem, also prolonged working life because the wear-resistant ceramic cover is arranged on the outer surface of metal body.The copper backing at wear-resistant ceramic cover two ends eases off the pressure when assembling, can protect the wear-resistant ceramic cover effectively, prevents that the wear-resistant ceramic cover is cracked, and can not come off in the process of using or loosening, has further improved working life.
