Description
Technical field
The present invention relates to field of petroleum exploitation, more specifically to a kind of multistage-combination gear oil-well pump.
Background technique
It is all often to take very large-scale equipment, such as beam type kowtowing machine etc. during exploiting oil field, these
Equipment is mostly extremely complex huge, and trouble difficult in maintenance, and driving process is also complex.For small-sized oil field, or for
The lesser oil exploitation process of scale, if a more exquisite oil exploitation device can be designed, it will be of great use.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of multistage-combination gear oil-well pumps, can be with an exquisite structure
Make the exploitation that oil field is realized with mode.
In order to achieve the above object, the present invention takes following technical scheme:
A kind of multistage-combination gear oil-well pump, including multiple gear pump modules arranged in the vertical direction, each gear
Pump module is made of multiple gear pumps mutually stacked, close on lower section one in the entrance of gear pump and same gear pump module
A gear pump outlet (thus in gear pump module positioned at least significant end gear pump oil inlet just no longer with its
He connects gear pump)；The oil well pump further includes oil pumping passage and oil discharge passage, oil pumping passage be located at each gear pump module most
The entrance of one gear pump of lower section is connected to, and oil discharge passage goes out with a gear pump positioned at each gear pump module the top
Mouth connection；
Gear pump can be crescent gear pump, including the internal gear as driving wheel and as the external gear of driven wheel,
The internal gear of each gear pump after transmission shaft rotates also by the vertically communicated connection driving of same root transmission shaft (to own
Gear pump can be driven and rotate together).
It may include three gear pumps in each gear pump module.
(thus motor driven transmission shaft) can be also connected to motor in transmission shaft.
The oil well pump may also include the pump case for fixing gear pump, and gear pump is fixed on pump case by quill bearing
Body.
The oil well pump may also include positioned at the oil pumping room of bottom, and interior of pumping is provided with check valve, and (oil pumping room is located at oil reservoir
Above well liquid, check valve control oil liquid can only flow to oil pumping room from oil reservoir and cannot flow to oil reservoir well liquid from oil pumping room), oil pumping is logical
Road is connected to oil pumping room.
The oil well pump may also include the output oil pipe for being connected to top, and oil discharge passage is connected to output oil pipe.
It is an advantage of the current invention that motor is directly connected to transmission shaft, so that it may realize the operating of all gear pumps, drive
Flowing mode is very simple；In addition, by be arranged in a gear pump module multiple gear pumps in the way of, increase each gear
The extraction force of pump module, and by the output oil liquid of each gear pump module be together in parallel in the way of, can be easily
Setting more multiple gearpump module is to improve efficiency；In addition to this, due to the plurality of advantages that gear pump itself has, the device
Just there are these following advantages: simple and compact, small in size, light weight, good manufacturability, cheap；Self-suction is strong, to oil contamination
The insensitive, range of speeds is big, can impact resistance load；Easy to maintain, reliable operation, energy conservation and environmental protection etc., this is for oil field
Exploitation, the exploitation in especially small-sized oil field are very convenient.

Specific embodiment
A specific embodiment of the invention is described with reference to the accompanying drawing.
It is as shown in Figure 1 oil well pump of the present invention along axial sectional view, basic principle of the invention is, passes through transmission shaft
2 rotation drives the rotation of multiple gear pumps, to (wherein include petroleum by oil reservoir well liquid 14；Oil recovery process will be toward ground undershoot
Enter water, drive petroleum to extract together using the pressure of water) oil pumping room 17 is first evacuated to by check valve 13, then successively lead to again
It crosses oil pumping passage 15, gear pump and oil discharge passage 4 and is evacuated to output oil pipe 1 positioned at top, oil well pump of the present invention is described below
Specific structure.
Still as shown in Figure 1, being located at bottom, there are three the gear pumps that mutually stack, from the bottom up respectively one-stage gear
Pump 12, secondary gear wheel pump 11 and tertiary gear pump 10.These three gear pumps one gear pump module of composition, and such gear pump
Module is arranged with many from the bottom up, and specific quantity can be determined (the gear pump quantity in gear pump module by actual conditions
It can also be determined by actual conditions, here as one embodiment has selected three).
What meaning does the division of gear pump module have since being all the arrangement of gear pump in the vertical direction?
In a gear pump module, the entrance of each gear pump and close on the most the tooth immediately below it
The outlet of wheel pump is connected by pump stage channel 7, but because below a gear pump of bottom in the gear pump module not
There is gear pump again, therefore the entrance of the gear pump of bottom is not just connect with the outlet of other gear pumps.In this way, a tooth
Take turns only one entrance and one outlet in pump module, be respectively a gear pump of its bottom entrance and the top one
The outlet of a gear pump, so, the function of a gear pump module are equivalent to the function of a gear pump, but this
The series connection of sample can allow the oil pumping ability of gear pump module to be improved.
Next, from be located at bottom oil pumping room 17 in draw an oil pumping passage 15, by this oil pumping passage 15 with
The entrance of each gear pump module is attached by parallel port 81 of pumping；Then again with one gear pump module of bottom
Outlet is starting point toward 1 direction of output oil pipe extension, one oil discharge passage 4 of extraction, which finally leads with output oil pipe 1
It is logical, but be attached with the outlet of each gear pump module by fuel-displaced parallel port 82 in road, in this way, each tooth
Wheel pump module can be transferred through same oil pumping passage 15 and pump, and can also be carried out by same oil discharge passage 4 fuel-displaced.
Certainly, entire oil well pump can not only have the above internal structure mentioned, and also have for fixed and closed interior
The pump case 3 of structure, and gear pump is fixed on pump case 3 by needle bearing 9, oil pumping passage 15 and oil discharge passage 4 are also opened
In pump case 3.
Fig. 2 shows the radial cutaway view of the oil well pump, it is mainly used for expressing the effect of gear pump.It can be seen that gear
Pump includes the lesser internal gear 6 of diameter, and the external gear 5 being relatively large in diameter, and internal gear 6 and external gear 5 engage, and forms one
Semi-moon shaped void area, oil liquid are exactly to be transmitted in this void area.It can be seen that being also provided with packing in gear pump
Crescent moon 16, these are all existing gear pump structures, and just few expansion set forth.
Pumping operation can be carried out by manpower rotating drive shaft 2 in principle, but can also be filled with motor or other drivings
Set the pumping operation for being attached and thus allowing for higher efficiency and more automating.
The foregoing is only a preferred embodiment of the present invention, but scope of protection of the present invention is not limited thereto,
Anyone skilled in the art within the technical scope of the present disclosure, according to the technique and scheme of the present invention and its
Inventive concept is subject to equivalent substitution or change, should be covered by the protection scope of the present invention.
