Abstract

The utility model discloses a device using gas pressure difference for directly improving liquid potential energy. The device is composed of a liquid lifting barrel, a gas path switcher and a switch controller. A liquid passage and a gas passage are arranged in the liquid lifting barrel. The pressure interlayer of every liquid level in the liquid passage is determined by pressure in the gas passage at intervals, and a high pressure passage and a low pressure passage are continually switched by the gas path switcher for causing liquid to continually flow from a high pressure layer to a low pressure layer. The main advantage of the device is that the lift of liquid which is lifted is far in excess of the height of liquid column corresponding to the pressure difference of air source, and also the device has simple structure and convenient operation.

Description

Liquid accumulative pump

Technical field is a kind of specific pump under the invention.

Reciprocating pump and rotor pump are modal liquid pumps, and with regard to its working principle, piston is the parts that reciprocating pump carries out energy interchange.Rotor then is the parts that rotor pump carries out energy interchange.And jet pump is a kind of common specific pump, though it is a kind of pump of ancient form, because it has certain advantage, so it in particular cases still can be widely used some, and forms a kind of special technology.Such pump has geneogenous shortcoming in view of principle, because it is to carry out momentum and energy transfer from the turbulent flow hybrid mode, so efficient is extremely low, generally is lower than 30%.

The fluid cumulative pump of the invention is a kind of pump of special shape, its structure and principle both be different from above-mentioned all kinds of pump, and with the patent No. be that 86203136 whirlwind windmill water pumping device also has a lot of differences, it is that 86203136 model utility is that the air pressure difference that utilizes whirlwind tower to form reaches the purpose of water lift step by step as power that patent is.Fluid cumulative pump of the present invention, available air, the pressure reduction of steam and other gas is as power, and this pump both can be used for flooding, and also can be used for improving the potential energy of oil or other fluid.Thus this pump except can part with the application for the quotation marks pump, and can open new application.As: utilize vapour pressure deficit to be used as power and can extract oil, utilize air pressure difference to be used as power and can extract corrosive fluid.

The utility model device is by extract tube (1), and gas circuit switch (2) and switch controller (3) are formed.Gas channels (4), (5) all place in the extract tube (1) with liquid paths (6), two-part before and after the extract tube is separated into along axle, first half is liquid paths (6), latter half of is gas channels (4), (5).Liquid paths (6) is divided into several layers, and the number of plies is decided as required.Have pipeline (7) to link to each other between each layer, have in the top of pipeline (7) to make liquid by the one-way cock (8) of underflow to the upper strata, the upper limb interlayer of each layer is alternate vent (9) or (10), and respectively with gas channels (4), (5) are communicated with.At the U of the superiors of extract tube (1) type liquid-discharging tube (11), it can drain, can proper functioning in the time of guaranteeing to be in low pressure in the superiors again.Feed liquor tube (12) is arranged at extract tube (1) bottom, on its barrel inlet opening is arranged, and extraneous liquid is flowed in the fluid cylinder (12) by cinclides.

Gas circuit switch (2) is by forming with lower member.Switch chamber (13), (14), pipeline (15), (16), (17), (18), control valve (19), (20), rotating shaft (21), bearing (22), crank (23), and by control valve (19), (20) make pipeline (16), (18) with pipeline (15), (17) are in alternately closed condition.

Switch controller (3) is by industrial electro magnet (24), and iron core (25), the ball float disconnected device that continues is formed.Be connected with flexible cord (29) between suspension rod (27) the other end on the ball float (26) and the three-way cock (28).

Further describe the concrete structure and the working procedure of the invention below in conjunction with accompanying drawing.

The accumulation of fluid pump, it switches chamber (13) and gas channels (4) is communicated with, switch chamber (14) and be communicated with gas channels (5), gas channels (4) is communicated with each chamber interbed of liquid paths (6) through vent (10) with liquid paths (6) or gas channels (5) through vent (9).

Pipeline (17), (18), (15), (16) one ends are fixed in and switch chamber (13), are communicated with pipeline (17) on (14) wall with it, (18) the other end is communicated with the source of the gas high voltage terminal, and the other end of pipeline (15), (16) is communicated with the gas source low pressure end.Rotating shaft (21) is by being fixed on the bearing (22) on the gas circuit switch and being communicated with switch controller on being fixed on the switch top cover by crank (23).

During the initial start-up of accumulation of fluid pump, at first by the manual switching gas circuit for a moment, fluid passage is in interbed very soon liquid status.When top when liquid is arranged, ball float (26) is in high position, circuit switch is in state shown in the right figure among Fig. 3, right side electromagnet (24) is charged, and valve (19) this moment (20) makes pipeline (15), and (17) are in closed condition, air-flow path (4) is connected with the source of the gas high voltage terminal, air-flow path (5) is logical with the gas source low pressure termination, and liquid level is in high pressure conditions in the top and downward odd-level of taking this as the standard of extract tube this moment (1), and liquid level is in low-pressure state in the even level simultaneously.So liquid is flowed out by U type liquid-discharging tube (11) in top, the liquid in the odd-level is by right side fluid passage (7), and one-way valve (8) flows to the upper strata.When the liquid in top drops to extreme lower position, ball float (26) then is in lower position, circuit switch is in state shown in the left figure among Fig. 3, left side electromagnet (24) energising, and right side electromagnet (24) circuit interruption, and control valve (19), (20) make pipeline (16), (18) be in closed condition, air-flow path this moment (4) is logical with the gas source low pressure termination, air-flow path (5) is connected with the source of the gas high voltage terminal, and the liquid in the even level passes through left side fluid passage (7), and one-way valve (8) is moving to upper stream.After liquid was full of in the odd-level, ball float was in the extreme higher position again, made right side electromagnet (24) work again, thereby made valve (19), and switch once more (20).So go down, liquid constantly flows into the upper strata by lower floor, is flowed out by U type waste pipe (11) at last.

The invention, simple in structure, available steel plate or plastic plate welding or compacting form. Security of operation, convenient management according to actual needs, increases the height of extract tube (1), in the situation that does not increase consume, reaches needed lift.
