Abstract
The utility model relates to a non-leakage sealing assembly of a reciprocating plunger pump, which comprises a plunger rod (4) and annular packings (5), wherein an alloy layer is arranged on the surface of the plunger rod (4), the section of each annular packing (5) is V-shaped and the boss part and the sunk part thereof can be engaged and contacted, and a plurality of annular packings (5) form a group of packings after being stacked and are sleeved on the plunger rod (4). The plunger rod of the non-leakage sealing assembly can not be damaged and is well sealed, sealing gaps can be automatically regulated after the packings are abraded, and the non-leakage sealing assembly has the characteristics of difficult leakage and no need of frequent replacement and reduces the labor intensity of workers and the payment of material expenses.
Description
Technical field:
The utility model relates to the drive unit reciprocating plunger pump in the oil recovery field, oil field, especially a kind of reciprocating plunger pump inclusion seal assembly.
Background technique:
At present, the aboveground plunger pump of oil-field flooding relies on packing and plunger rod to fit tightly mostly and realizes sealing.Packing is a nylon material, the cross section is a square, and the packing group is become by a plurality of packing stack faces, because plunger pump is continuously worked, sealed packing produces wound to the surface of plunger rod, produce to leak behind the surface fracture of plunger rod, in addition, along with the increase packing of service time also can cause wearing and tearing, gap between itself and the plunger rod is increased, and then make sealing part produce leakage, and so just must often change sealed packing and plunger rod, influence ordinary production.
The model utility content:
In order to overcome the deficiency that exists in the background technique, the utility model provides a kind of reciprocating plunger pump inclusion seal assembly, this inclusion seal assembly plunger rod can not be damaged good seal, and packing can be regulated seal clearance automatically after wearing and tearing, have the advantages that to be difficult for the generation leakage and need not often to change, reduced the expenditure of working strength of workers and Master Cost.
The technical solution of the utility model is: this reciprocating plunger pump inclusion seal assembly comprises plunger rod annular packing, there is alloy-layer on the surface of plunger rod, touch mutually for " V " type and its projection section can coincide with sunk part in the cross section of annular packing, and some annular packings stack back one group of packing of composition and are enclosed within on the plunger rod.
Above-mentioned annular packing inner bottom part has annular groove; Stack back one group of packing upper and lower end of composition and be equipped with the termination up and down that the termination is the plane respectively, there is annular groove the upper-end surface of upper tip; The material of annular packing is a rubber.
The utlity model has following beneficial effect: because touch mutually for " V " type and its projection section and sunk part can coincide in the cross section of taking the annular packing in the such scheme, some annular packings are stacked together and form one group, after annular packing is squeezed, the annular packing expands, remedied the gap that increases between annular packing and the plunger rod, can regulate seal clearance automatically, be difficult for producing and leak, need not often change.The surface of plunger rod has alloy-layer to increase the intensity of plunger rod, and plunger rod is difficult for being made its good seal prevent seepage by damaged.
Description of drawings:
Accompanying drawing 1 is a structural representation of the present utility model.
1-packing box among the figure, 2-packing cover, 3-packing gland, 4-plunger rod, 5-annular packing, 6-groove.
Embodiment:
The utility model is described in further detail below in conjunction with accompanying drawing:
As shown in FIG., this reciprocating plunger pump inclusion seal assembly comprises plunger rod 4 and annular packing 5, and the surface of plunger rod 4 is coated with wear-resistant alloy layer, and alloy-layer has increased the intensity of plunger rod, and plunger rod is difficult for being made its good seal prevent seepage by damaged.Touch mutually for " V " type and its projection section can coincide with sunk part in the cross section of annular packing 5,3～12 annular packings 5 stack back one group of packing of composition and are enclosed within on the plunger rod 4, stack back one group of packing 5 upper and lower end of composition and be equipped with the termination up and down (7 that the termination is the plane respectively, 8), the termination (7 up and down, 8) upper and lower end has packing cover 2, one groups of annulars packing 5 and packing cover 2 to place in the packing box 1 respectively, and packing box 1 lower end screw thread is connected with packing gland 3.Touch mutually for annular packing 5 its projection sections of " V " type and sunk part can coincide in the cross section, the annular packing is stacked together and forms one group, after annular packing is squeezed, the annular packing expands, remedied the gap that increases between annular packing and the plunger rod, can regulate seal clearance automatically, be difficult for producing and leak, need not often change.
Annular packing 5 inner bottom parts have annular groove 6, and there is annular groove 9 upper-end surface of upper tip 7, after water inlet in the packing, expand after being full of the water pressurized in groove 6 and the annular groove 9, have remedied the gap between annular packing and the plunger rod, prevent seepage.
The material of annular packing 5 is a rubber, and the annular packing 5 of rubber material is difficult for worn piston bar 4, can prolong the working life of plunger rod 4, and makes good seal.
Claims (4)
1. reciprocating plunger pump inclusion seal assembly, comprise plunger rod (4) and annular packing (5), it is characterized in that: there is alloy-layer on the surface of described plunger rod (4), touch mutually for " V " type and its projection section can coincide with sunk part in the cross section of described annular packing (5), and some annular packings (5) stack back one group of packing of composition and are enclosed within on the plunger rod (4).
2. reciprocating plunger pump inclusion seal assembly according to claim 1 is characterized in that: annular packing (5) inner bottom part has annular groove (6).
3. reciprocating plunger pump inclusion seal assembly according to claim 1 is characterized in that: stack back composition one group of packing (5) upper and lower end and be equipped with the termination up and down (7,8) that the termination is the plane respectively, there is annular groove (9) upper-end surface of upper tip (7).
4. reciprocating plunger pump inclusion seal assembly according to claim 1 is characterized in that: the material of annular packing (5) is a rubber.
