Abstract
The utility model discloses a kind of high pressure resistant anti-dropping type ceramic plunger, its inner core is a metallic material, overcoat is the special cermacis thick walled tube, take the Bond bonding between ceramic coat and the metal inner core, take interference fit simultaneously, metal inner core one end is provided with metal backup shoe, takes bolt to be connected between gland and the metal inner core, corrosion-resistant, the wear-resistant Bond of gland outer end brushing, special ceramic material comprises aluminium oxide, zirconium oxide, silicon nitride, Zirconia reinforced alumina.This structure has well solved under high pressure frangible, the caducous problem of ceramic component in the ceramic plunger, and it is widely used in the industries such as oil, geologic prospecting and chemical industry, prolongs the working life of product greatly, reduces enterprise's cost of production.
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 anti-dropping type 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 adopts the method for chromium plating, coated with hard alloy, carburizing or carbonitriding, nitriding treatment more at present, under the industrial and mineral mal-condition, be difficult to normal the use, life-span is short, quality of product does not reach requirement, or costs an arm and a leg.
Three, summary of the invention
The purpose of this utility model is to provide a kind of high pressure resistant anti-dropping type ceramic plunger of being made 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 this utility model is achieved in that a kind of high pressure resistant anti-dropping type ceramic plunger, it is characterized in that: its inner core (1) is a metallic material, and overcoat (2) is the special cermacis thick walled tube; Take Bond (3) bonding between ceramic coat (2) and the metal inner core (1), take interference fit simultaneously; Metal inner core (1) one end is provided with metal backup shoe (4), takes bolt (5) to be connected between gland (4) and the metal inner core (1), gland outer end brushing corrosion-resistant, wear-resistant Bond (6); Special ceramic material comprises aluminium oxide, zirconium oxide, silicon nitride, Zirconia reinforced alumina.
High pressure resistant anti-dropping type ceramic plunger of the present utility model, its inner core is a metallic material, overcoat is the special cermacis thick walled tube, take the Bond bonding between ceramic coat and the metal inner core, take interference fit simultaneously, metal inner core one end is provided with metal backup shoe, takes bolt to be connected between gland and the metal inner core, corrosion-resistant, the wear-resistant Bond of gland outer end brushing, special ceramic material comprises aluminium oxide, zirconium oxide, silicon nitride, Zirconia reinforced alumina.This structure has well solved under high pressure frangible, the caducous problem of ceramic component in the ceramic plunger, and it is widely used in the industries such as oil, geologic prospecting and chemical industry, prolongs the working life of product greatly, reduces enterprise's cost of production.
