Now illustrate the running principle of the device based on above-mentioned listed assembly.

Be suitable for this running principle manufacturing installation, be mounted with the fluid of rule by its flow valve (6).Guarantee that the closing valve (20) above turbine chamber closes, simultaneously, once set suitable tap to regulate fluid, the liquid level of the corresponding large-scale reservoir chamber (1) of such as pipeline (C), pipeline (8) corresponding heat exchanger chambers (7), pipeline (13) corresponding suction tube (11) discharge section and pump (12), the correct setting of fluid level in complete twin installation in fluid regulation process, heat exchanger chambers starts to fill by tap (15), after the liquid level being suitable for this running principle completes and presets, should guarantee that all fluids flow through part and do not hinder, thus damage correct operation cycle, simultaneously, once device is loaded by rule, its running program is pneumatic.

By opening the large size valve (D) being arranged at top, reservoir chamber (1), the fluid brought in device that negative pressure is brought into heat exchanger chambers (7) and continued by the whole fluids in up-hill line (5), in device, whole force value is limited by atmospheric pressure (state of rest).

By these values, the fluid in heat exchanger chambers (7) has higher negative pressure value.From up to down, the pressure condition that the value in heat exchanger chambers (7) is determined by device height: upwards chamber (1) force value is conceited presses the pressure risen to storing greatly in chamber (1), nominal atmospheric pressure to self-exchange chamber (7) towards storing greatly, equal.

In suction tube (11), there is identical pressure equally, suction tube (11) is immersed in the fluid compensating and store chamber (10) completely, store chamber (10) with compensation to be connected with storage chamber (1) is through on phase same level, its startup depends on that large storage chamber (1) is at the pressure of its maximum height under negative pressure.

In the descending post chamber that self-pumping (12) begins, there is identical negative pressure equally, down to compensating chamber (14) with tube chamber (19) until the turbo machine (26) of below has the pressure identical with larger storage chamber (1).(from point 12, there is negative pressure, to putting 26, there is barometric pressure.）

When all these positive pressure value or possible negative pressure force value appear in when needs 12 exchange air pump inoperative (state of rest).

For creating a favo(u)rable case of the dynamic moving of fluid, pump (12) should be work, certainly storage chamber (1) larger in suction tube (11) is to the inflow entrance formative dynamics negative pressure field of pump (12), and it is identical with the aforementioned static subnormal ambient that static-pressure field is formed in heat exchanger chambers (7).

Meanwhile, the fluid leaving pump (12) presents positive pressure state, shunted and flowed out negative pressure from malleation and enter the effect of pump (12), thus changed from label 12(pump) to label 26(turbo machine) the pressure state of downstream pip, comprise the pressure state of air chamber for subsequent use (17).The pressure state that the flow flowed out and pump (12) produce must be compensated in attached taper bucket (16), attached taper bucket extends to nearly cone-shaped collection chamber (16) and vertically with tube chamber (19) to arrange, store chamber (14) and air chamber for subsequent use (17) by compensating it is integrally connected with tube chamber (28), and on the horizontal position being arranged at device.In above-mentioned situation, the pressure of efflux pump (12) likely can to fall to label 26 from label 12 accelerated and reset because of fluid, secondly, the fluid of whereabouts leaves under gravity acceleration discharges taper bucket (27), directly falls to entering to store greatly chamber (1) to flow back in device circulation.

Hereafter the pressure produced in the operation of this device will be described.

The process of device load fluids is described above.

In addition, in this embodiment, operating process is similar, will produce positive pressure.According to device natural structure, by manufacturing pressure in the tap (E) storing chamber (1), pressure can be made to inject not restriction.

The only difference of said apparatus there is different force value: storing greatly in chamber (1) and air chamber for subsequent use (17), there is malleation extreme value, and exist in the heat exchanger chambers (7) and store greatly pressure low compared with chamber (1).

Large storage chamber (1) and air chamber for subsequent use (17) have identical pressure, because the two is connected by pipeline (21), pipeline (21) is by the control of valve pipe (21a) and (21b).

In the present embodiment, for discharging the fluid stored greatly in chamber (1), select the pipeline on suitable diameter and surface according to device estimated pressure.

With reference now to Fig. 2, illustrate second preferred embodiment of apparatus of the present invention.Following assembly is disclosed in Fig. 2:

Plant running principle based on aforesaid assembly will hereinafter be described.

The routine that the device adapting to this operation carries out fluid by tap (18') is loaded.Before pneumatic loading, should guarantee that top tap (15') and (16') open.Start once device routine is loaded, form water level (A), (B) and (C), device has completed to run and has prepared.

By pneumatic pump motor (4'), fluid starts (1') to be transported to chamber (5') from chamber: chamber (1') the fluid (9') entered at the flows by action of gravity accleration from downstream pip that is reduced to of fluid space is provided; This dynamic state come from chamber (1') with chamber (8') in gas, form requisite space, and by fluid, (2') dynamic power fed to turbo machine.

In fluid flowing, chamber (5') in, the movement of fluid in the local of up-hill line (7') tube chamber, (4') pump will produce the gravity of single opposite force, its from pump outflow opening (4') oppositely to pipeline outflow opening (6'), thus be beneficial to pumping system can the limit flow of load.

Pump (4') in the pressure that produces by according to downstream pip (9') in tube chamber height import turbine chamber pressure (1'), thus make from turbine chamber (1') the fluid that comes and pump discharge the fluid that (5') chamber discharge and realize exchanging.

Because of chamber (1') in pressure and capacity situation and chamber (5') in pressure and capacity situation will balance, again because gas density when pressure increases only increases an extremely low percentage, chamber (1') in gas pump is aspirated and (2') turbine is discharged.

The fluid (4') carried of pump and chamber (5') in fluid junction: the different pressures that (4') pump produces is formed fluid and (8') (9') flows to the accelerator of turbo machine (2') in process by gathering with downstream pip by being connected chamber.

The different pressures that (4') up-hill line intended diameter (7') should produce according to pump and determining: with obtain flow to up-hill line fluid total volume (7') and downstream pip (9') in flow to turbo machine fluid total volume (2'); Because the slip velocity of fluid is only decided by the different pressures that (4') pump produces in up-hill line (7), downstream pip (9') in liquid speed be decided by that acceleration that gravity produces simultaneously, the size suitable for calculating pipeline is very necessary.

Device described in this specification details and running principle thereof; be interpreted as only enumerating two preferred embodiments; and under the condition not departing from basic principle of the present invention, scope; its various change, amendment, increase and/or replacement parts, to form independent establishment, all fall into the protection domain of invention claim.
