Abstract
The utility model relates to a driven well pump auto-compensation plunger piston gland bush comprising a plunger piston (1) which comprises a spring seat (5), a plunger spring (4), a package (3) and an oil distributing loop (6) according the order, wherein the adjusting gland bush (7) and the sleeve (2) are respectively disposed at the two ends of the plunger and connected with each other to form the shell, the module is covered by the shell, the lock ring (8) and the lock ring (9) are respectively disposed on the inner side and the outer side of the oil distributing loop (6), the airproof of the plunger and the sleeve (2) can be achieved, the fluid coolant inlet port A and B are disposed in the sleeve (2), the smooth and the cooling of the plunger piston (1) and the package (3) can be achieved. As the spring auto-compensation pressing force is adopted, the plunger piston and the package are forcibly lubricate and refrigerated, the airproof is safe and reliable, and thereby the device is suitable for the working pressure 0-105MPa shuttle conveyer driven well pump.
Description
Technical field:
The utility model belongs to the plunger sealing device in the petroleum natural gas exploration usefulness reciprocating drilling pump.
Background technique:
Three cylinder single-acting drilling pumps of domestic production manufacturing at present all adopt the cylinder sleeve piston structure.On behalf of drilling pump, the plunger type drilling pump can bear higher pressure, but realizes that safe and reliable sealing configuration is a present difficult problem.
Summary of the invention:
The utility model purpose provides a kind of drilling pump auto-compensating plunger sealing device of high reliability, satisfies the demand of high pump pressure.
Specifically, the utility model is to solve the problems referred to above by following technical solution:
Drilling pump auto-compensating plunger sealing device, it comprises that being docile and obedient preface is contained in spring seat (5), piston spring (4), packing (3) and each assembly of distribution oil ring (6) on the plunger (1); Adjusting gland (7) and cylinder sleeve (2) are contained in plunger (1) two ends respectively and by connecting and composing housing each assembly are coated; Seal ring (8) and (9) are contained in the inboard of distribution oil ring (6) and the outside respectively and realize sealing to plunger and cylinder sleeve (2); Metalworking coolant import A and the outlet B of realization to the lubricated and cooling of plunger (1) and packing (3) arranged on the cylinder sleeve (2).
Described packing (3) is made up of the sealing of plastics and two kinds of unlike materials of rubber, and assembling at interval.
The utility model reaches the forced seal of packing to plunger owing to adopt spring to compensate impacting force and pressure lubrication cooling automatically, has the reliable sealing characteristics.The utility model adopts the spring plunger seal structure of compensation automatically, and working pressure can reach 0-105MPa.
