Abstract
The utility model discloses a pressurized water injection pump which is composed of a base, a crankshaft pulley, a box body, an inner and an outer packing boxes, a pump head, a plunger, a lead assembly of a pressure gauge, a connecting plate of a balance pipe and the balance pipe, wherein, the inner of the pump head is provided with a combined valve. A small hole on one end of a drain channel is communicated with the balance pipe. A small hole on one end of a pipetting channel is communicated with the lead assembly of the pressure gauge. The utility model has the advantages that the integral pump head reduces leakage points; the combined valve reduces valve checking workload and raises work efficiency; repositioned accessory members including a balancing pipe assembly and the lead assembly of the pressure gauge eliminate unsafe factors in operating procedure and provide convenience for management.
Description
The utility model relates to a kind of water injection pump, belongs to the oil field equipment water injection equipment.
The frequent high pressure water injection equipment that uses in oil field is the 3ZY-4/37 hydraulic resistance balance boosting water injection pump that General Machinery Plant, Dagang Petroleum Administration produces at present.This pump partly is made up of power end part and fluid end, and power end partly comprises base, parts such as the bent axle of wheel, connecting rod, crosshead, crosshead tappet, casing thong; Fluid end partly comprises parts such as inside and outside packing box assembly, discharge opeing menifold, imbibition menifold, flap type, pump head, plunger, balance tube, pressure gauge lead-in wire assembly, end cap flange.This pump has the following disadvantages in the production use and management: 1, former pump head is split type, by the main pump head with advance the discharge opeing manifold and form, especially change combination valve for maintenance and cause certain difficulty (needs three people operate simultaneously); 2, split type pump head assembly structure seal point is many, easy to leak; 3, pressure gauge lead-in wire assembly is installed in imbibition menifold bottom, and easily the contamination precipitation that liquid is carried is in imbibition menifold bottom, and retaining pressure table wire jack causes the indication of pump inlet pressure inaccurate.
The purpose of this utility model is exactly the shortcoming that overcomes prior art, and a kind of boosting water injection pump is provided.
The purpose of this utility model is achieved in that boosting water injection pump is by base, crank pulley, casing, outward, interior packing box, pump head, plunger, pressure gauge lead-in wire assembly, the balance tube tie-plate, balance tube is formed, pump head is linked to each other with casing by fixing bolt, pump head top has apocenosis passage, the bottom has the imbibition passage, the middle part has three plunger service aisles and three valve group working barrels, in the valve group working barrel combination brake switch and proporting is housed, combination brake switch and proporting is by the imbibition valve seat, the imbibition valve block, the liquid sucting valve gland, the discharge opeing valve seat, the discharge opeing valve block, the discharge opeing gland, the valve pressure head, the valve gland flange is formed.The terminal aperture of apocenosis passage communicates with balance tube, and imbibition channel end aperture communicates with pressure gauge lead-in wire assembly.
The utility model compared with prior art has the following advantages: 1, implement whole pump head, reduced leakage point; 2, adopt combination brake switch and proporting, inspection valve workload reduces, and has improved work efficiency; 3, associate member balance tube assembly and pressure gauge lead-in wire assembly position change is eliminated the operating process unsafe factor, is convenient to management.
Below in conjunction with accompanying drawing the utility model is described further:
Fig. 1: the utility model plan view; Fig. 2: the utility model plan view;
Fig. 3: the utility model A is to view; Fig. 4: B-B sectional view;
As Fig. 1,2,3, shown in 4, boosting water injection pump is by base 1, crank pulley 2, casing 3, outward, interior packing box 4,5, pump head 8, plunger 10, pressure gauge lead-in wire assembly 12, balance tube tie-plate 13, balance tube 14 is formed, pump head 8 is linked to each other with casing 3 by fixing bolt, pump head 8 tops have apocenosis passage 7, the bottom has imbibition passage 21, the middle part has three plunger service aisles and three valve group working barrels, in the valve group working barrel combination brake switch and proporting is housed, combination brake switch and proporting is by imbibition valve seat 18, imbibition valve block 20, liquid sucting valve gland 11, discharge opeing valve seat 17, discharge opeing valve block 19, discharge opeing gland 16, valve pressure head 15, valve gland flange 6 is formed.Apocenosis passage 7 terminal apertures communicate with balance tube 14, and balance tube 14 links to each other with outer packing box balance tube joint again, has guaranteed counterbalance effect, and imbibition passage 21 terminal apertures communicate with pressure gauge lead-in wire assembly 12.Avoid the pressure gauge wiring to be stopped up by impurity.
When power end drives plunger 10 motions, pump head 8 active chamber internal pressures reduce, imbibition passage 21 liquid squeeze opens suction valve disc, liquid flows in the active chamber, and behind the plunger motion certain position, the work intracavity liquid of making is squeezed, pressure raises, imbibition valve block 20 is closed under spring action, and expulsion valve is opened, and liquid is pushed to discharge opeing runner 7.In movement process, when working pressure was high, liquid became buffering by flinging, and separating liquid is between feed liquor gland and the pump head active chamber, effectively prevented the pump head fracture, prolonged pump head working life, reduced pressure pulsation simultaneously.
