Description
Technical field:
A kind of electromechanical integrated product that relates to machinery, hydraulic pressure, electrical equipment control is used for the oil recovery in oil field and the coal-bed gas exploitation in colliery.
Background technology:
At present, the oil field generally uses three to take out system's (oil pumper, sucker rod, oil well pump) and carry out oil producing operation; Emerging coal gas industry also is to use this three systems of taking out to carry out water pumping gas production.This three take out oil pumper used in the system or water pumper mostly is beam pumping unit, are commonly called as " machine of kowtowing ".
The many oil fields of China have all entered the exploitation later stage, and for the annual production that guarantees crude oil as much as possible is unlikely to descend significantly, people have to develop in a large number some stripper wells, low seepage well, thereby need some small-sized oil pumpers; Emerging coal gas industry is buried more shallow (2000 meters with shallow) because of the coal seam, and load is less, and what need also is small-sized oil pumper.Original " machine of kowtowing " because of bulky, from great, reasons such as floor space is big, energy consumption height, can not adapt to this demand well.
In view of above problem, field produces and coal-bed gas exploitation need a kind of volume little, from heavy and light, and easy transportation and installation, energy-conservation small-sized oil pumping, pumping equipment.
Rui Te group is inspired confidence in Shandong, develops single crank coal bed gas oil pumper (water pumper) on the basis of traditional beam pumping unit, and it is dwindling in proportion of " machine of kowtowing " basically.BOSCH-REXROTH company has also released oil cylinder vertical type small-sized hydraulic oil pumper.These machines have been received good effect in the oil field or colliery operation, and some are better but still need development, more small-sized suitable oil pumper (water pumper).
Summary of the invention:
It is little that the present invention is intended to provide a kind of volume, in light weight, simple in structure, is easy to transport, install the small-sized oil pumper (water pumper) that efficiency is high.
The invention provides a kind of vertical type rack-and-pinion oil pumper (water pumper) of fluid motor-driven, as Fig. 1, Fig. 2, Fig. 3, shown in Figure 4.Its overall structure comprises seven major parts, main frame (1), and counterweight support (2), guiding wheels (3), counterweight wire rope (4), counterweight basket (5) adds Hydraulic Station and electric control box.Main frame (1) links to each other with wellhead flange by the mounting bracket (6) of its underpart, stands on the well head; Oil pumping polish rod passes from the centre bore (15) of tooth bar (13), and is fixing with light bar cramp; Under the control of electric control box, Hydraulic Station produces pressure oil and drives hydraulic motor (9) rotation; The rotation of hydraulic motor is rotated in opposite directions by the motor gear (10) in the transmission case (4), idle gear (11), travelling gear (12), drive pair of driving wheels gear (14); Two driving wheels (14) that rotate in opposite directions drive the upper and lower motion of tooth bar (13), and oil pumping polish rod is realized the oil pumping action in company with the upper and lower together reciprocating motion of tooth bar (13); Counterweight wire rope (4) one ends are connected the top of tooth bar (13), are connected above the ballast box (5) after the last twice 90 degree commutations of two commutation wheels (3) of the other end on being installed on the counterweight support.Rack housing (8) is installed in the top of transmission case (7), is enclosed within the outside of tooth bar (13).
The vertical type rack-and-pinion oil pumper (water pumper) of fluid motor-driven of the present invention, its power resources are in hydraulic motor (9), hydraulic motor produces under the effect of hydraulic oil and rotatablely moves, and thisly moves through the upper and lower reciprocating motion that gear train assembly becomes tooth bar (13).Hydraulic Station produces pressure oil, enters two chambeies of hydraulic motor by oil piping system, and a side is an oil suction chamber, and opposite side is an oil back chamber just.Three position four-way directional control valve is being controlled the break-make and the commutation of oil stream, and the commutation of oil stream makes and the hydraulic motor counter-rotating realizes the commutation of oil pumping polish rod.
The vertical type rack-and-pinion oil pumper (water pumper) of fluid motor-driven of the present invention; its electric control part branch comprises conventional electric motor starting, halt circuit; the start and stop circuit of oil pumping action; comprise upper and lower stroke switch (16) (17) in addition; the left and right sides coil and the safety protective circuit of three-position four-way valve; as surpassed distance protection, liquid-level switch etc.

The specific embodiment:
Counter-balanced carriage (2), counterweight basket (5), mounting bracket (6) is mainly welding structural element, amount of machining seldom on it; Transmission case also is welded by steel plate, and postwelding need carry out normalized treatment, to eliminate welding stress, prevents to produce distortion after the machine, carries out machine then, mainly is to bore each bearing mounting hole; Gear shaft, gear etc. all are to use high-quality structural steel machining to form; With hydraulic motor, gear shaft, the transmission case (7) of packing into such as gear, the bottom that then mounting bracket is connected to casing promptly constitutes main frame.Main frame is installed on the wellhead flange by mounting bracket, and oil pumping polish rod passes from the tooth bar centre bore, gets final product with the polished rod clamp is fixing above transmission case; Counter-balanced carriage (2) straddle mounting is in main frame (1) top, two columns are fixed on the ground with stone bolt, two guiding wheels (3) are installed on the crossbeam of counter-balanced carriage top, and counterweight wire rope one end is connected the top of tooth bar (13), and the other end is connected on the counterweight basket after successively walking around two directive wheels.Upper and lower stroke switch (16) (17) is installed in the inboard (near the tooth bar side) of mounting bracket, cooperates with the electromagnetic coil at three-position four-way hydraulic reversal valve two ends, is controlling the length and the commutation position of stroke.Consider that oil pumper needs long-term around the clock continuous operation,, can use two drivings with hydraulic motors (9) for increasing its reliability, the using and the reserved, motor gear (10) correspondingly, idle gear (11) also all has two covers.The course of work of the vertical type rack-and-pinion oil pumper (water pumper) of fluid motor-driven is as follows:
When the spool of three-position four-way hydraulic reversal valve is in meta, two oil pocket mouths of confining liquid pressure motor (9), hydraulic motor can not just change, and can not reverse; When the spool of three-position four-way hydraulic reversal valve is in position, a left side, a chamber oil-feed of hydraulic motor (9), another chamber oil return, forward rotation rises sucker rod, finishes the oil pumping operation, and counterweight is fallen in the key simultaneously, with the rising of its potential energy power-assisted sucker rod; When the inductor on the tooth bar made upper stroke switch (16) action, the spool of three-position four-way hydraulic reversal valve was changed to right position, and the oil suction chamber and the oil return of hydraulic motor (9) replace by force, and backward rotation descends sucker rod, and the counterweight basket rises simultaneously, accumulates potential energy; When the inductor on the tooth bar made lower stroke switch (17) action, the spool of three-position four-way hydraulic reversal valve was changed to position, a left side, begins next working cycles.
