To pump, the present embodiment uses eccentric crankshaft and bevel gear pair, naturally it is also possible to will can vertically be revolved using other
Transhipment is dynamic to be converted into the structure pumped, and therefore not to repeat here.
The operation principle of the present invention is as follows：
Electric energy is delivered to the submersible electric machine with oil of underground by oil-submersible cable 1 by ground driving equipment from ground, makes submersible electric machine with oil
Moment of torsion is produced between stator 13 and submersible motor rotor 12, so as to drive submersible electric machine with oil axle 14 to rotate；Submersible electric machine with oil axle 14 drives
The upper little gear 8 of upper stage plunger module and the lower little gear 15 of subordinate's plunger module rotate, and pass through the upper He of deceleration reversing assembly 7
Tilt motions are converted into by lower deceleration reversing assembly 16 to pump；The upper little gear 8 of upper stage plunger module drives
Upper stage plunger 6 is reciprocating, and the lower little gear 15 of subordinate's plunger module drives push rod 17 and subordinate's plunger 18 reciprocating；
And upper stage plunger 6 is opposite with the direction of motion of subordinate plunger 18；
When push rod 17 and subordinate's plunger 18 are moved downward, the compression lower spring 20 of subordinate's plunger 18 makes lower spring accommodating cavity
Volume diminish (at the same time the volume of negative pressure cavity VI becomes big), the hydraulic oil in lower spring accommodating cavity balances oil duct through hydraulic oil
32 flow into the oily working chamber II of lower hydraulic, become the pressure in the oily working chamber II of lower hydraulic and top hydraulic working oil chamber III
Greatly；The pressure acts on upper stage plunger 6 by the lower surface of upper stage plunger 6, makes the motion upwards of upper stage plunger 6；At the same time, on
The upper little gear 8 of level plunger module drives upper stage plunger 6 to move upwards by upper deceleration reversing assembly 7, then upper stage plunger 6 is by under
Pressurization and submersible electric machine with oil produced by level plunger module is to the double action of the driving force of upper stage plunger 6；Upper stage plunger 6 to
Spring 5 in upper motion, compression, and power is passed into barrier film 3 by hydraulic oil, make the motion upwards of barrier film 3, in well liquid accommodating cavity V
Middle generation malleation, this malleation forces liquid valve 11 to open (while closing liquid feed valve 10), so that by well liquid accommodating cavity V
Well liquid is expelled in oil pipe 25 by well liquid outlet 2；
When the pressure in bottom hydraulic working oil chamber II and top hydraulic working oil chamber III rises to the unlatching of overflow valve 21
After pressure, overflow valve 21 can be forced to open, it is unnecessary in lower hydraulic oil working chamber II and top hydraulic working oil chamber III
Hydraulic oil can be backflowed to hydraulic oil storage chamber I by hydraulic oil overflow passage 33, so that lower hydraulic oil working chamber II and upper
Pressure in portion's hydraulic working oil chamber III maintains setting value.
After upper deceleration reversing assembly 7 and lower deceleration reversing assembly 16 reset, push rod 17 and subordinate's plunger 18 are acted on
Thrust is disappeared, and push rod 17 and subordinate's plunger 18 are moved upwards in the presence of the reseting elasticity of lower spring 20, now lower hydraulic
Distress resolves in oily working chamber II and top hydraulic working oil chamber III, the volume of lower spring accommodating cavity becomes big and produces negative pressure, one
Section hydraulic oil balances oil duct 32 by hydraulic oil and added in lower spring accommodating cavity, and not enough part is by make-up valve 19 from liquid
Force feed storage chamber I is added in lower spring accommodating cavity through hydraulic oil fluid infusion passage 31；
Upper stage plunger 6 or is moved downward in the reseting elasticity of upper spring 5 in the presence of the driving force of submersible electric machine with oil, is made
Barrier film 3 is moved downward, and negative pressure is produced in well liquid accommodating cavity V, and this negative pressure forces liquid feed valve 10 to be opened (while making liquid valve 11
Close), so that extraneous well liquid is sucked in well liquid accommodating cavity V by well liquid suction inlet 9.
The present invention drives upper stage plunger 6 and subordinate's plunger 18 to do work simultaneously by submersible electric machine with oil, i.e., subordinate's plunger 18 is downward
Upper stage plunger 6 is moved upwards while motion, and moving downward for subordinate's plunger 18 can produce upward power to upper stage plunger 6,
To realize that relay lifts effect, so as to reach higher work lift than common latent oil membrane pump.
The present invention is provided with negative pressure cavity VI in the top of subordinate's plunger 18, when push rod 17 and subordinate's plunger 18 move downward it is same
When upper stage plunger 6 move upwards, the volume of the oily working chamber II of lower hydraulic and top hydraulic working oil chamber III is become big, and lower bullet
The volume of spring accommodating cavity diminishes, while negative pressure cavity VI becomes big；Because negative pressure cavity VI becomes big, the volume of lower spring accommodating cavity is set to diminish
Measure the volume that (i.e. the oil extraction volume of lower spring accommodating cavity) is more than the oily working chamber II of lower hydraulic and top hydraulic working oil chamber III
Become a large amount of, so that the amount of liquid flowed into from lower spring accommodating cavity is more than the oily working chamber II of lower hydraulic and top hydraulic working oil
The volume variable quantity of chamber III, finally makes the pressure in the oily working chamber II of lower hydraulic and top hydraulic working oil chamber III become big.
Although embodiments of the present invention are hereinbefore described in detail, show for those skilled in the art
And be clear to, various modifications and variations can be carried out to these embodiments.However, it is understood that this modifications and variations are all
Belong within the scope and spirit of the present invention described in claims.Moreover, the present invention described herein can have others
Embodiment, and can be practiced or carried out in several ways.
