Abstract
The utility model discloses a high-pressure-resisting reproducible ceramic plunger. An inner core of the high-pressure-resisting reproducible ceramic plunger is made of metal, an outer sleeve of the high-pressure-resisting reproducible ceramic plunger is a special ceramic thick-wall pipe, and the ceramic outer sleeve and the metal inner core are adhered by an adhesive; a plug and a location step are arranged at one end of the metal inner core and are integrated with the metal inner core; a metal gland is arranged at the other end of the meal inner core, the metal gland and the metal inner core are connected through a thread, and the gland, the plug and the ceramic outer sleeve are of smooth transition; four threaded holes are arranged at the center of the plug; and the special ceramic material comprises the following components of aluminum oxide, zirconium oxide, silicon nitride, zirconium-oxide toughened aluminum oxide, and metal ceramic. According to the structure of the high-pressure-resisting reproducible ceramic plunger disclosed by the utility model, the installation and the detachment of the plunger are convenient; simultaneously, the problem that a ceramic component is easy to be broken and removed in the ceramic plunger under high pressure is greatly solved, and the problem that the plunger does not lock a pump under a condition of high-speed operation is solved at the same time; and the high-pressure-resisting reproducible ceramic plunger disclosed by the utility model is widely applied to industries of petroleum, geological exploration, chemistry and the like, greatly prolongs the service lives of products and reduces production costs of corporations.
Description
One, technical field
The utility model relates to pump that occasion such as wear-resisting in the industries such as oil, chemical industry, geologic prospecting, high temperature resistant, corrosion-resistant the uses a kind of mechanical device with ceramic plunger, particularly relates to a kind of high pressure resistant renewable ceramic plunger.
Two, background technique
Plunger is a kind of mechanical device of the pump that uses of occasion such as wear-resisting in the industries such as oil, chemical industry, geologic prospecting, high temperature resistant, corrosion-resistant with ceramic plunger; The easily worn part of the similar device that occurs on the domestic and international market at present adopts the method for chromium plating, coated with hard alloy, carburizing or carbonitriding, nitriding treatment more; Under the industrial and mineral mal-condition, be difficult to normal the use; Life-span is short, and quality of product does not reach requirement, or costs an arm and a leg.
Three, summary of the invention
The purpose of the utility model is to provide a kind of high pressure resistant renewable ceramic plunger of being processed by big, wear-resistant, corrosion-resistant, the anti-special ceramic material that washes away of hardness; And, original piston structure has been made corresponding change overcome the existing in prior technology deficiency according to the performance that stupalith itself has.
The purpose of the utility model is achieved in that a kind of high pressure resistant renewable ceramic plunger, it is characterized in that: its inner core (2) is a metallic material, and overcoat (4) is the special cermacis thick walled tube; Take Bond (3) bonding between ceramic coat (4) and the metal inner core (2); Metal inner core (2) one ends are provided with plug (6) and positioning step (5), and plug (6) and positioning step (5) are integrated with metal inner core (2); Metal inner core (2) the other end is provided with metal gland (1), takes to be threaded between gland (1) and the metal inner core (2), takes smooth transition between gland (1) and plug (6) and the ceramic coat (4);----four screw holes (7) that are provided with one in the plug center.
The high pressure resistant renewable ceramic plunger of the utility model, its inner core are metallic material, and overcoat is the special cermacis thick walled tube, take the Bond bonding between ceramic coat and the metal inner core; Metal inner core one end is provided with plug and positioning step, and plug and positioning step and metal inner core are integrated; The metal inner core the other end is provided with the metal gland, takes to be threaded between gland and the metal inner core, takes smooth transition between gland and plug and the ceramic coat;----four screw holes that are provided with one in the plug center; Special ceramic material comprises aluminium oxide, zirconium oxide, silicon nitride, Zirconia reinforced alumina, ceramet.This structure has made things convenient for the installation and removal of plunger; Well solved simultaneously under high pressure frangible, the caducous problem of ceramic component in the ceramic plunger; Solved plunger problem of holddown not under the situation of running up simultaneously; It is widely used in the industries such as oil, geologic prospecting and chemical industry, prolongs the working life of product greatly, reduces the enterprise production cost.
Four, description of drawings
Fig. 1 is the cross-sectional schematic representation of the high pressure resistant renewable ceramic plunger of the utility model.
Five, embodiment
Below in conjunction with accompanying drawing the utility model is done detailed description.
Like a kind of high pressure resistant renewable ceramic plunger of Fig. 1, it is characterized in that: its inner core (2) is a metallic material, and overcoat (4) is the special cermacis thick walled tube; Take Bond (3) bonding between ceramic coat (4) and the metal inner core (2); Metal inner core (2) one ends are provided with plug (6) and positioning step (5), and plug (6) and positioning step (5) are integrated with metal inner core (2); Metal inner core (2) the other end is provided with metal gland (1), takes to be threaded between gland (1) and the metal inner core (2), takes smooth transition between gland (1) and plug (6) and the ceramic coat (4);----four screw holes (7) that are provided with one in the plug center.
