Abstract
The utility model relates to a plunger piston seal box press sleeve, in particular to a plunger piston seal box press sleeve used in various type plunger pumps in an oil field high-low pressure water injection system. The utility model adopts the technical scheme that the plunger piston seal box press sleeve comprises a plunger pump assembly, a press sleeve, a plunger piston and a press cap, wherein the plunger pump assembly is provided with a spring and a packing set, the outer side of the opening end of the plunger pump assembly is provided with an external screw, the press cap is provided with an internal screw which is matched with the external screw of the plunger pump assembly, the plunger piston threads through the press sleeve and the press cap, and is located in the plunger pump assembly, the inner surface of the press sleeve is provided with an inner groove, an oil storage lubricating seal ring is arranged in the groove, and a through hole is arranged between the inner groove and the outer surface of the press sleeve. The plunger piston seal box press sleeve has the beneficial effects of extending the replacing cycle of plunger pump packing seal and reducing the abrasion of the packing set to the plunger piston, thereby greatly reducing wastage of materials, reducing the maintaining workload, and effectively reducing the maintaining cost of the plunger pump.
Description
One, technical field:
The utility model relates to a kind of plunger seal letter gland, particularly a kind of plunger seal letter gland that is used for the various model plunger pumps of oil field high low pressure flood pattern.
Two, background technique:
At present, the plunger seal letter gland of various model plunger pumps that is used for oil field flood pattern is very universal, the main orientation of plunger and the parallel pressuring action of packing of rising, but the problem that exists is: the parallel pressuring action that only plays plunger orientation and packing, do not lubricate and the sealing cooling effect, behind the plunger pump long-play, cause gland wearing and tearing and fouling easily; Cause plunger pump to open pump shroud pump difficulty, increase workload, difficult in maintenance; Packing wearing and tearing, sintering lose seal action; The plunger wear aggravation; Gland weares and teares, fouling is serious, even plunger is stuck.Pump efficiency reduces, and materials consumption is serious.
Three, summary of the invention:
The purpose of this utility model is exactly the defective that exists at prior art, and a kind of lubricating type plunger seal letter gland with orientation, lubricated, seal action is provided.
Its technological scheme is: the utility model comprises plunger pump assembly, gland, plunger and pressure cap, be provided with spring and packing in the plunger pump assembly, the plunger pump assembly opening end outside is provided with outer silk, pressure cap is provided with the internal thread that matches with the outer silk of plunger pump assembly, plunger passes gland and pressure cap is positioned at plunger pump assembly inside, internal surface at described gland is provided with inner groovy, is provided with oil storage lubrication and seal circle in the groove, is provided with a through hole between inner groovy and gland outer surface.
Effect of the present utility model is: owing to be provided with inner groovy at the interior toroidal surface of plunger packing sealed letter gland, and be connected by the through hole outer surface, rise and inject the i.e. oiling on the oil storage seal ring of moderate lubrication oil in the pump forward direction gland through hole, and open the dish pump work before the pump.Such effect is: play preceding plunger of pump and packing and obtained lubricating, alleviated the preceding dish pump load of a pump, increased the packing_seal effect, gland has been had plunger and the lubricated effect of lowering the temperature of packing.Prolonged the replacement cycle of post match pump packing sealing, reduced the wearing and tearing of packing plunger.Spillage of material is reduced greatly, and maintenance workload lowers, and has effectively reduced the maintenance cost of plunger pump.
Four, description of drawings:
Accompanying drawing 1 is a structural representation of the present utility model;
Accompanying drawing 2 is structural representations of the utility model gland.
Five, embodiment:
With reference to attached Fig. 1 and 2, the utility model comprises plunger pump assembly 1, gland 5, plunger 8 and pressure cap 7, be provided with spring 2 and packing 3 in the plunger pump assembly 1, the plunger pump assembly 1 opening end outside is provided with outer silk 4, pressure cap 7 is provided with outer silk 4 internal threads that match 6 with plunger pump assembly 1, plunger 8 passes gland 5 and pressure cap 6 is positioned at plunger pump assembly 1 inside, internal surface at described gland 5 is provided with groove 10, be provided with oil storage lubrication and seal circle 12 in the groove 10, between groove 10 and gland 5 outer surfaces, be provided with a through hole 11.
Claims (2)
1, a kind of plunger pump stuffing sealing letter gland, comprise plunger pump assembly, gland, plunger and pressure cap, it is characterized in that: be provided with spring and packing in the plunger pump assembly, the plunger pump assembly opening end outside is provided with outer silk, pressure cap is provided with the internal thread that matches with the outer silk of plunger pump assembly, and plunger passes gland and pressure cap is positioned at plunger pump assembly inside.
2, lubricating type plunger seal letter gland according to claim 1, it is characterized in that: the internal surface at described gland is provided with inner groovy, is provided with oil storage lubrication and seal circle in the groove, is provided with a through hole between inner groovy and gland outer surface.
