Abstract
A reciprocating piston type water injection pump packing box two-positioning device resolves the defects of the prior reciprocating piston type water injection pump packing boxes which adopt single positioning method to cause cylinder scuffing accidents of the packing box and the box easily, wherein a pump head (7) is fixedly connected with a box body (3), one end of a packing box (4) is fixedly connected with the box body (3) via a packing box flange (5), the inner hole of the packing box (4) is communicated with the pump head (7), one end of the packing box (4) far from the pump head (7) is provided with a packing box support base II (9) fixedly connected with the box body (3), the inner hole of the packing box support base II (9) is coaxially arranged with the inner hole of a packing box support base I (8). The utility model has the advantages that the reciprocating piston type water injection pump packing box two-positioning device can stably keep the axis line of a packing box horizontal, to confirm the coaxial state between the plunger and the packing box, thereby effectively preventing cylinder scuffing of the packing box and crosshead, to prolong the service lives of the elements such as the packing box and the plunger, and confirm the stable operation of water injection pumps.
Description
Affiliated technical field
The utility model relates to a kind of reciprocating plunger type water injection pump, especially relates to a kind of reciprocating plunger type water injection pump packing box double positioner.
Background technique
Along with the continuous increase of oilfield exploitation time, many oil fields have entered development late stage.In order to realize crude oil stable high yield, usually adopt the reciprocating plunger type water injection pump to carry out water filling and exploit.At present, the end face position structure that the packing box of reciprocating plunger type water injection pump plunger mostly adopts the packing box flange to be connected with casing with stud bolt, as shown in Figure 1.In use, influence because of factors such as the vibration of plunger pump and packing box deadweights, the bolt that the packing box flange is connected with casing reaches fatigue limit easily and produces distortion, the axis of packing box is difficult to keep level, influence the coaxality of crosshead and packing box, thereby cause the packing box scuffing of cylinder bore, even cause casing heating, the generation of crosshead scuffing of cylinder bore accident.
The model utility content
Take single orientation type in order to overcome existing reciprocating plunger type water injection pump packing box, cause the deficiency of the generation of basin root box, casing scuffing of cylinder bore accident easily, the utility model provides a kind of reciprocating plunger type water injection pump packing box double positioner.
The technological scheme that its technical problem that solves the utility model adopts is: reciprocating plunger type water injection pump packing box double positioner comprises pump head, casing, plunger, packing box, packing box flange, packing box gland, bolt, pump head is fixedlyed connected with casing, one end of packing box is fixedlyed connected with casing by the packing box flange, the packing box endoporus communicates with the pump head hole, plunger is along the to-and-fro motion of packing box endoporus, away from pump head one end packing box supporting base II is arranged at packing box, packing box supporting base II is fixedlyed connected with casing; Packing box supporting base II and casing are one; Packing box supporting base II endoporus is coaxial with packing box supporting base I endoporus.
The beneficial effects of the utility model are, can make the packing box axis stably keep level, guarantee that plunger is coaxial with packing box, effectively avoid packing box and crosshead scuffing of cylinder bore, prolong the working life of parts such as packing box, plunger, guarantee that the water injection pump running state is steady.
Description of drawings
Fig. 1 is known reciprocating plunger type water injection pump packing box position structure schematic representation.
Fig. 2 is the utility model reciprocating plunger type water injection pump packing box double positioner structural representation.
Among the figure: 1. plunger, 2. packing box gland, 3. casing, 4. packing box, 5. packing box is sent out orchid, 6. bolt, 7. pump head, 8. packing box supporting base I, 9. packing box supporting base II.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing 2 and embodiment.
The utility model reciprocating plunger type water injection pump packing box double positioner comprises pump head 7, casing 3, plunger 1, packing box 4, packing box flange 5, packing box gland 2, and pump head 7 is positioned at casing 3 outsides, fixedlys connected with casing 3; Packing box 4 is positioned at casing 3 inboards, and an end of packing box 4 is fixedlyed connected with casing 3 by packing box flange 5, connects with bolt 6 usually; The cylindrical of packing box 4 is positioned at casing 3 packing box supporting base I8 holes; Packing box 4 endoporus communicate with the hole of pump head 7, and plunger 1 is along packing box 4 endoporus to-and-fro motion.Away from pump head 7 one ends packing box supporting base II9 is arranged at packing box 4, packing box supporting base II9 is fixedlyed connected with casing 3, adopts casting technique that packing box supporting base II9 and casing 3 are cast into one usually.When machining box, guarantee packing box supporting base II9 endoporus and packing box supporting base I8 endoporus coaxality and levelness, the axis horizontal degree of packing box 4 in the time of can guaranteeing to assemble.
The utility model reciprocating plunger type water injection pump packing box double positioner owing to adopted double locating structure, makes water injection pump work running state steady, reduces rate of breakdown, prolongs the working life of water injection pump.
Claims (3)
