After assembling the turbine in the form shown in Figure A.l, Figure A.2, Figure A.3. 1. Manufactured material:

In general, Gaspressure - liquid turbine does not require any special material, however: If the selected solvent is a corrosive substance (such as water), surfaces exposed to the solvent should be painted or coated a layer of chemical corrosion resistant material; In case of special conditions such as high temperature, suitable design should be adjusted such as: choosing the appropriate solvent, using heat resistant seal ring...

2. Solvent:

The solvent used is a liquid (to create a floating environment in the water of the gas flow), the solvent may be selected according to different criteria, eg: Choose a boiling point (if Turbine structured with gas flow emerged in water by pressure works with high- temperature gas flow such as thermodynamics, or choose non-corrosive chemicals to ensure durability of the exposure parts. However, for optimal power and performance, to choose heavy and flexible liquids.

When operating, the level of solvent (7b) in the tank (7), equal to the solvent level (3q) in the working box(3a).

3. Rotatiom.Gaspressure - liquid turbine can rotate clockwise or counterclockwise:

- When selecting the rotation direction of clockwise, the position of the Shield (4) is positioned as shown in Figure D. l

- When selecting the rotation direction of counter-clockwise, the position of the Shield (4) is positioned as shown in Figure D.2.

5. Operating:

a.Startup: At startup, the gas inlet valve must be opened and the turbine must be rotated in the

direction of gasflow inward, in the direction of the Shield (4a) (same clockwise, with the position of the Shield). (4) as shown in Figure Dl, counterclockwise, with the position of the Shield (4) as shown in Figure D.2). The speed equals the velocity floating in the water (solvent) of the gas flow, until the solvent level is stable, to start the turbine.

b. Operating:

- Suction period:When the working box (la) passes through the gas inlet (3b), it remains in the state of an open box, the gas - pressure from the gas inlet enters a certain volume of the box, about 1/2 to 1 /3 of working box volume(la) when reaching the Gas inlet.

- Period of power generation: As soon as passing through the gas inlet (3b). The working box (la) is covered by a closed box (the outside of the box is covered by the casing 3, the inner cover of the

box is covered by the shield 4a), so that: power is preserved, The gas block lifting force acts on the underside of the blade, forcing the rotor around the working direction during the journey.

- Discharge periodfWhen going to the Gas outlet (3c), the working box (la) becomes the power

generated open gasbox that easily exits out.

The working boxes (la) in turn receive gas- generatepower - escape sequentially, make the turbines rotate evenly. (At the beginning, the level of solvent will rise higher than the normal level, equivalent to the volume of gas occupied immediately, then: solvent flows through the container and stabilize the solvent level as the original, then tassel bin has been in nonnal working state).

Example:

Example 1 : Use Gaspressure - liquid turbine to exploit gassource - pressure of 0.05 kg /cm² .

To exploit an gas source - pressure of 0.05 kg / cm with Turbine structured with gas flow emerged in water by pressure, if the solvent is Water (H²0), we can use Turbine structured with gas flow emerged in water by pressure with a working box diameter of 500 mm to generate electricity or water pump .. etc ...

Example 2 : Use Gaspressure - liquid turbinewith heat - live gas, gas-pressure at high temperature.

For gas - live gas, pressure at high temperature as much as Gaspressure - liquid turbine, suitable boiling temperature is chosen (can be heavy oil), selected heat resistant seal gland, seal

ring.

Example 3 :UseTurbine structured with gas flow emerged in water by pressure to exploit gas- pressuresource at high pressure .

Gaspressure - liquid turbinecan also be used to exploit high pressuregas sources, by: Large diameter turbine design, or connection in series of multiple turbines on angas - pressure source

(similar to Continuously load the load into the current).

Example TUseGaspressure - liquid turbine to collect power from gas source - pressure lower than air pressure.

When using anGaspressure - liquid turbine to collect power from an gas - pressure source with pressure lower than the air pressure, we choose the Gaspressure - liquid turbine diameter to match the pressure difference of the gas flow, then connect the source to the outlet ofGaspressure - liquid turbine.

Effect of the invention:
