トン５は往復動を繰り返す。Next, the operation of the water pump using the recycle pressure booster according to this embodiment will be described focusing on the flow of air. The air pressure switching valve 1 is connected to the supply pipe 2 by about 12 kg /
The compressed air inside and outside the cm 2 G is sent to the pressure chamber 6 on one side of the air cylinder 4, and the pneumatic piston 5 is moved. on the other hand,
The air in the pressure chamber 7 on the other side of the air cylinder 4 is pushed out by the pneumatic piston 5 to generate about 5 to 7 kg /
With a residual pressure of about cm 2 G, it returns to the switching valve 1, passes through the reflux pipe 3, and returns to the low-pressure tank 51. The compressed air having a residual pressure of about 5 to 6 kg / cm 2 G returned is about 8 kg / cm from the low pressure tank 51 to the first booster compressor 52.
The pressure is increased to 2 G, further increased to about 12 kg / cm 2 G by the intermediate pressure tank 53 and the second pressure increasing compressor 54, stored in the high pressure tank 55, and passed through the receiver tank 56, It is sent again to the switching valve 1 via the supply pipe 2. In the switching valve 1, the flow of air is switched at predetermined time intervals, compressed air of about 12 kg / cm 2 G is sent to the pressure chamber 7 on the other side of the air cylinder 4, and the pneumatic piston 5 is moved to one side of the air cylinder 4. Move to side 6.
As a result, the air in the pressure chamber 6 on one side of the air cylinder 4 is pushed out by the pneumatic piston 5, and the air pressure is reduced to about 5 to 6
Returning from the reflux pipe 3 to the low-pressure tank 51 leaving a residual pressure of kg / cm 2 G. In this way, the pneumatic piston 5 repeats reciprocating motion.

In this case, the air pressure of the compressed air is initially about 12 kg / cm 2 G, which is consumed for the reciprocation of the air piston 5, and is 5 to 6 kg / cm.
It is recirculated as compressed air having a residual pressure of about 2 G. The recycle pressure boosting apparatus according to this embodiment regenerates compressed air having a residual pressure of 5 to 6 kg / cm 2 G, which has been conventionally discharged into the atmosphere, to a high pressure to enhance the energy saving effect when pumping water. It is a thing.

る。In the pushing mechanism, the compressed air is pressure-fed to the main body of the second booster compressor 54 by the same operation as that described for the first booster compressor. The use of two two-stage reciprocating compressors in series means that increasing the pressure of compressed air requires increasing the amount of work by increasing the pressure to the final predetermined value with the one-stage reciprocating compressor. Because it is bad. That is, if the number of stages is increased, it is cooled by the intercooler after the pressure is increased by one stage and the temperature is lowered to the outside air temperature. Therefore, if the pressure in the second stage is increased from that state, the work amount is reduced and the efficiency is improved. However, if one large-capacity reciprocating compressor having a large number of stages is adopted, the initial cost will be high. Therefore, two two-stage reciprocating compressors are arranged in series. Actually, the first booster / compressor 52 has a positive pressure up to about 8 kg / cm 2 G and the second booster / compressor 54 has a pressure of 8 k / cm 2.
Pressure is applied from g / cm 2 G to about 12 kg / cm 2 G.

徴とする。As described above, according to the present invention, in a water pump and a power generation system using the same, a low pressure tank for storing residual pressure air on the air pressure source side of a return pipe and residual pressure air from the low pressure tank. A first pressure boosting compressor for sucking in, a medium pressure tank for storing discharge compressed air of the first pressure boosting compressor to prevent pressure fluctuation, and a first pressure boosting medium pressure compressed air from the medium pressure tank to a predetermined pressure value 2. A booster compressor, a high-pressure tank that stores the compressed air discharged from the second booster compressor and prevents pressure fluctuations, and a receiver tank that relays the compressed air from the high-pressure tank are connected in series, and the receiver is provided. A tank is connected to the supply pipe, and the first and second booster compressors are reciprocating compressors in which the number of stages can be selected.

率なものにすることができる。Therefore, the first and second booster compressors can be reciprocating compressors each having a number of stages, and since two compressors are provided in series, one reciprocating compressor with one stage can be used. Compared with using a type compressor, it requires less work, and because two units are arranged in series, the number of stages can be reduced, so compared to a large-capacity reciprocating compressor with many stages. Initial cost can also be reduced. Then, compressed air with a residual pressure (plus pressure) is kept at a predetermined value (5 kg / cm
Since it can pressurize to 2), it is more energy-saving and less wasteful than pressurizing from zero such as the introduction of outside air, and it is intended to make the pump and the power generation system using it more efficient. You can
