Abstract
A multi-cylinder adjustable injecting device for a hydraulic plunger piston mainly aims to solve the problems of inaccurate injection volume and poor operating stationarity of the prior injecting device, and is characterized in that a hydraulic gate valve group (2) for a hydraulic station (1) is communicated with one to six hydraulic cylinders (3) communicated with a plunger piston for a meteringpump the lower end of which is communicated with a valve body (10), a liquid inlet (4) and a liquid outlet (5) where non-return valves are arranged are arranged on the valve body (10), the liquid inlet (4) is communicated with an injecting tank, and the liquid outlet (5) is communicated with an injecting well. The multi-cylinder adjustable injecting device for the hydraulic plunger piston has theadvantages of accurate injecting volume and good operating stationarity.
Description
Technical field:
The utility model relates to used injecting device, the especially hydraulic plunger multi-cylinder adjustable injection device of oil recovery field, oil field displacing oil underground.
Background technology:
In oil recovery field, oil field,, adopt the purpose that reaches the raising recovery ratio to the examination of oil reservoir injecting displacement of reservoir oil side in order to improve recovery ratio.And injecting need inject oil reservoir with liquid with the injecting device.And at present used injecting device exists the injection rate inaccuracy owing to reasons in structure, owing to adopt machine driving, vibration is big, running stability is poor, influences the injecting effect.
Summary of the invention:
In order to solve the problem of existing injecting device injection rate inaccuracy, running stability difference, the utility model provides a kind of hydraulic plunger multi-cylinder adjustable injection device, this hydraulic plunger multi-cylinder adjustable injection device have the injecting amount accurately, the characteristics of injection volume and good operational stability.
The technical solution of the utility model is: this hydraulic plunger multi-cylinder adjustable injection device comprises Hydraulic Station, the Hydraulic Station hydraulic valve bank is connected with 1-6 hydraulic cylinder by pipeline, hydraulic cylinder is connected with the measuring pump plunger again, the pump barrel lower end of measuring pump is communicated with valve body, inlet and leakage fluid dram are arranged respectively on the valve body, in inlet and the leakage fluid dram one way valve is arranged, inlet is connected with the injecting jar, and leakage fluid dram and injecting well are logical.
Hydraulic cylinder in the such scheme is 3; Be communicated with accumulator on the hydraulic valve bank; Be in series with return filter on the hydraulic valve bank return line.
The utlity model has following beneficial effect: this hydraulic plunger multi-cylinder adjustable injection device is owing to adopt Hydraulic Station and structure that hydraulic cylinder is connected with measuring pump, the characteristic of utilizing hydraulic system to operate steadily, thereby realization accurate measurement, the purpose of even running.Thus this hydraulic plunger multi-cylinder adjustable injection device have the injecting amount accurately, the characteristics of injection volume and good operational stability.
Description of drawings:
Accompanying drawing 1 is the utility model structural representation;
Accompanying drawing 2 is Fig. 1 vertical views;
Accompanying drawing 3 is Fig. 1 left views.
1-Hydraulic Station among the figure, 2-hydraulic valve bank, 3-hydraulic cylinder, 4-inlet, 5-leakage fluid dram, 6-accumulator, 7-return filter, 8-plunger, 9-pump barrel, 10-valve body.
The examination of concrete enforcement side:
The utility model is described in further detail below in conjunction with accompanying drawing:
Shown in accompanying drawing, this hydraulic plunger multi-cylinder adjustable injection device comprises Hydraulic Station 1, Hydraulic Station 1 is made of fuel tank, motor, hydraulic pump and hydraulic valve bank 2, the hydraulic valve bank 2 of Hydraulic Station 1 is connected with 3 hydraulic cylinders 3 by pipeline, power source by Hydraulic Station 1, hydraulic valve bank 2 and the reciprocal easy motion of hydraulic cylinder 3 formations drives measuring pumps by hydraulic cylinder 3 and moves back and forth.Hydraulic cylinder 3 is connected with the plunger 8 of measuring pump again, pump barrel 9 lower ends of measuring pump are communicated with valve body 10, and inlet 4 and leakage fluid dram 5 are arranged respectively on the valve body 10, in inlet 4 and the leakage fluid dram 5 one way valve are arranged, inlet 4 is connected with the injecting jar, and leakage fluid dram 5 is logical with the injecting well.When the measuring pump feed liquor, inlet 4 is opened, and leakage fluid dram 5 is closed, and injecting enters in the pump barrel 9 of measuring pump; When the measuring pump discharge opeing, inlet 4 is closed, and leakage fluid dram 5 is opened, and injecting injects in the injecting well.Be communicated with accumulator 6 on the hydraulic valve bank 2.Be in series with return filter 7 on hydraulic valve bank 2 return lines.
During actual the use, at first the inlet on the valve body 10 4 is connected with the injecting jar, leakage fluid dram 5 is logical with the injecting well, opening Hydraulic Station 1, hydraulic cylinder 3 moves reciprocatingly under the control of hydraulic valve bank 2, the plunger 8 that while hydraulic cylinder 3 also drives measuring pump moves reciprocatingly, when the plunger 8 of measuring pump moves upward, the one-way valve opens of inlet 4 on the valve body 10, the closed check valve of leakage fluid dram 5 on the valve body 10, injecting inspiration pump barrel 9, when the plunger 8 of measuring pump moves downward, the closed check valve of inlet 4 on the valve body 10, the one-way valve opens of leakage fluid dram 5 on the valve body 10, injecting is annotated in the injecting well, reaches metering accurately and the purpose of the injecting of even running, has the value of applying.This invention is because the employing hydraulic system is carried out work, thereby the equipment overall operation is steady.
