Description

Energy Efficient Fluid Series Tandem Circulator {omitted}

The present invention is a fluid device that converts the specific kinetic energy of a fluid, which is a liquid or gas, into mechanical energy or converts mechanical energy into kinetic energy of a fluid.

It is to improve the energy utilization efficiency of the air motor using the compressed air.

Compared to electric motors, air motors have many advantages, such as small size, light weight, simple structure, easy repair in case of breakdown, safety in overload, no risk of fire, but the efficiency of using compressed air energy is less than 10%. It is so low that there are many restrictions on its use.

Among the fluid equipment, windmills that convert the movement of atmospheric air into power and air motors that convert the movement of compressed air into power use the same principle.

Although gaseous air flow has been used as a power generating device for a long time, a single device with a simple structure was not used because of low energy use efficiency, and the development of technology using air flow as a power was very weak.

After the Industrial Revolution, the rapid spread of thermodynamic energy devices of external and internal combustion engines caused serious atmospheric pollution problems,

Starting from the developed countries of Europe and America, as part of the development of technology to utilize clean energy sources without pollution as a power, much efforts have been made to improve the efficiency by developing fluid equipment that converts the movement of compressed air into power.

Starting with a windmill type winged device, a lot of effort has been made to improve the efficiency of a single unit, relying on precision machining technology such as piston type, rotary type and turbo type. Compressed air energy use efficiency of motor products is less than 10%,

Because of the limitations, the use of compressed air in a parallel configuration of a single device prevents further energy efficiency improvements.

Although it has many advantages in terms of operation characteristics, the compressed air energy use efficiency is less than 10%, which improves the air motor energy use efficiency of the single device parallel configuration, which is a conventional method of use, which is restricted in use. There is a challenge to improve above.

This problem can be solved by applying the principle of the tandem multi-stage turbine to increase the efficiency of the steam turbine by connecting the air motor which is a kind of fluid equipment in series to configure the circulation device.

The circulating device is constructed by making the case of fluid equipment in a completely sealed type that does not leak fluid such as compressed air or high pressure gas refrigerant and connecting it in series to the pipe through which compressed air passes.

In order to develop a highly efficient fluid equipment series connection circulator that can obtain a large amount of rotational power by the movement of a certain amount of fluid flow.

Energy that the subject innovation apparatus was a type of fluid device, including a special power unit improves the automation device or to be a range of use extended to portable tools, such as compressed air energy be the efficiency of the air motor to be utilized in the industry universally High efficiency fluid equipment series connection circulator .

Hereinafter, with reference to the accompanying drawings will be described a detailed configuration and detailed operation principle of the device.

1 is an installation system diagram using an air motor in a conventional manner in parallel with respect to compressed air flow.

The air motors AM1 to AM3 are driven in parallel by using compressed air packed in the compressed air tank (AT) by the electric motor drive compressor (EMC), and the three air motors each compress a certain amount of air. Air is being released to the atmosphere.

In this case, the dynamic energy that can be gained by using compressed air can be calculated as the product of compressed air mass and velocity squared (E = MXV ² X 1/2) and has a greater effect on the velocity of the flowing fluid compared to the mass of the fluid. You will see that you receive.

Since there is a large loss of fluid kinetic energy at the compressor suction side and the discharge side of the air motor, the consumption of compressed air increases by multiple depending on the number of air motors in which the devices are driven in parallel. EMC) requires very large capacity.

2 is an installation system diagram of using an air motor in a series-connected circulation system configuration for compressed air flow.

In FIG. 2, in order to improve the drawback that the single device parallel configuration of FIG. 1 utilizes less than 10% of the power that can be obtained by the air motor compared to the power required to fill the compressed air, the air motor series circulation circuit It is installed to improve the efficiency of compressed air energy use.

At this time, there should be no air leakage in the air motor series connection circulation system. If the compressed air passing through the air motor connected in series consumes the same amount of compressed air as one air motor in FIG. 1, the 8 air motors connected in series (AM1-AM8) Since the compressed air flowing through the inside is the same, the rotational force that drives the air motor is almost the same.

At this time, the capacity of the electric motor drive compressor (EMC) filling the compressed air is to fill the compressed air consumed by one air motor, so the output energy that can be obtained by the air motor is reduced while the energy input to the air compressor is reduced. It can be used relatively largely.

3 is an installation system diagram consisting of three-way valves and pipes to run / stop according to the needs of users among a plurality of fluid equipment connected in series.

4 is a diagram showing the overall installation system utilizing the energy-efficient fluid equipment series connection circulation device . It is configured to send in compressed air to the air motor, or by-pass while driving or to select a stop to energy-efficient fluid devices connected in series circulator-way valve (3WV6 3WV1) when you want.

The device of the present invention improves the compressed air energy use efficiency by overcoming the limitations of the use of air motors, which are smaller in size, simpler in structure, and have many advantages compared to electric motors, because the compressed air energy use efficiency is low.

As described above, by improving the parallel installation configuration of a single air motor having a low efficiency of using the compressed air energy of less than 10%, and configuring a series-connected circulation device, a plurality of air motors are consumed while consuming a small amount of compressed air. By obtaining the rotational force, an energy efficient fluid equipment series connection circulator is provided.
