Bushing 9, the bottom of piston cylinder 8 is provided with inlet valve 11, and inlet valve 11, the sealing of piston cylinder 8 constitute B cavitys 24;There is oil in B cavitys 24
12, B cavitys 24 are connected by one-way cock 7 with plunger case 21, and plunger case 21 is internally provided with hollow plunger 18, plunger 18
On be fixed with fixed pulley 19, load 20 is connected with fixed pulley 19;Whole plunger case 21 is located on base 6;The A of plunger case 21
Cavity 23 is connected by pipeline and time switch 5 with the C cavitys 25 of the bottom of piston cylinder 8;C cavitys 25 are connected to by pipeline 4
On oil storage tank 1, valve 3 and pump 2 are installed on pipeline 4.
As shown in figure 3, described piston 10 is shaped as cylindrical shape, primarily to increasing sealing.
Operation principle of the invention is as follows:
Before normal startup, the liquid oil got ready in fluid reservoir 1 is extracted into C cavitys 25 with pump 2 first, adjusted in the process
Whole switch 5, is at open state, and liquid oil enters among C cavitys 25 and A cavitys 23.With increasing for liquid, pressure meeting
The top of inhaling valve 11 is opened, into B cavitys 24, after waiting piston cylinder 8 and plunger case 21 hydraulically full, motor is closed, while twisting
Tight valve 3.
The pumping process of hydraulic oil pumping unit:
Upstroke:Motor 17 is opened, it passes through reduction box 26 and drives crank 16 to be rotated down, and the movement locus of crank 16 is
Circumference;Crank 16, connecting rod 15 and crossbeam 14 are three bar linkage structures, and its rear of middle cross beam 14 is fixed on support 13, center section
It is sliding sleeve 28, during three link motions, sliding sleeve 28 can force the guide post 27 under it to move downward.Due to the work of pressure
With inlet valve 11 is now in closed mode, and the internal liquid of B cavitys 24 passes through one-way cock 7 because pressure is acted on and enters A chambers
Body 23, i.e. plunger case, during this, time switch 5 is closed;The increased pressure in the inside of A cavitys 23 can make plunger 18
Motion upwards, so as to be moved upwards by fixed pulley band dynamic load 20 thereon, shaft bottom crude oil is given rise to ground by realization.
Down stroke:By setting the time of time switch 5, when plunger 18 rises to top dead-centre, switch 5 is opened;Now,
Liquid oil in A cavitys 23 is flowed into C cavitys 25 by pipeline, and the fluid pressure in A cavitys 23 is decreased, under plunger 18
Drop, load 20 declines also with plunger, and when top dead-centre is dropped to, time switch 5 is automatically switched off again.
The time of time switch 5 is determined that the time that it is in closing is identical with the time opened by the discharge capacity of real work,
Equal to the time of upper and lower stroke.That is, in upstroke, time switch 5 is closed;In down stroke, time switch 5 is opened.
Originally the sensor of well head sets related parameter values, and the sensor of well head connects the signal of well head, achieves
Change according to well head flow (well head flow volume change values be more than a certain setting value) and the power of threephase asynchronous 17 is entered
Row regulation and control.
