である。(Prior Art) A conventional fluid pumping device using pressure fluid pressure uses a prime mover to rotate the compressor to compress and pump fluid. In this fluid pumping device, for example, as described on pages 1044 to 1045 of the Control Engineering Handbook, the increase in discharge pressure due to a decrease in the pumping amount is controlled by a valve installed in the discharge pipe to the limit that does not cause surging. The discharge amount is adjusted by throttling the fluid, or by using a discharge pressure or discharge flow rate adjustment valve installed in the branch pipe, the compressed fluid is reduced in pressure and returned to the suction pipe of the compressor by bypass control. It is common to adjust the discharge pressure or flow rate to maintain the same.

絞り込むこと、及び一度圧縮したガスを減圧して
再度圧縮することになるため、動力損失が大きく
圧送量の減少幅が、大きくなるほど動力損失が極
めて大きくなるという問題がある。 This is because the discharge side of the compressor is throttled to a certain extent by a valve, and the once compressed gas is decompressed and then compressed again, so the power loss is large and the larger the decrease in the pumped amount, the more the power is reduced. The problem is that the loss becomes extremely large.

While maintaining the discharge pressure or discharge flow rate at a predetermined value, the pressure of the compressed gas is converted into rotational force by the expansion turbine, and the rotational force is transmitted to the compressor via the clutch to generate the power of the prime mover required for compression. The purpose is to reduce the

Controls the opening degree of 12. Further, the controller 14 outputs a control signal for controlling the engagement and separation of the rotation transmission device, for example, the clutch 6, to the rotation transmission control device 15.

The output signal of the discharge pressure or discharge flow rate controller 14 is inputted, and the rotation detector 16-1
The rotational speed signal of the rotating shaft 4 of the compressor 1 and the rotational speed signal of the reduction shaft 4' of the expansion turbine 2 from the rotation detector 16-2 are inputted, and the rotational speed of the reduction shaft 4 of the expansion turbine 2 is input to the compressor. The clutch 6 is engaged so as to operate within a specified range equal to or greater than 1 rotational speed. As a result, the rotational force of the rotating expansion turbine 2 is transmitted to the compressor 1 side,
Apply rotational force to the compressor 1. This reduces the power required for the prime mover 3 to rotate the compressor 1 by the amount of transmitted rotational force.

When the rotational speed of the compressor 1 is lower than the rotational speed of the compressor 1, the clutch 6 is open and no power is transferred, and the compressed fluid that has passed through the expansion turbine 2 is passed through the expansion turbine discharge pipe 11 and then into the compressor suction pipe 8. It expands (depressurizes) to the internal pressure and returns to the compressor suction side.

なり、対応できない。 In addition, by changing the rotation speed of the prime mover 3, the compressor 1
It is conceivable to adjust the discharge pressure and discharge flow rate from the engine, but when the rotation speed is decreased, the discharge pressure decreases in proportion to the square of the decrease in rotation speed, and the discharge flow rate also decreases in proportion to the decrease in rotation speed. On the other hand, since the plant to which the compressed gas is supplied requires a certain discharge pressure, the situation is such that the constant discharge pressure cannot be achieved and it cannot be dealt with.
