摘要： PROBLEM TO BE SOLVED: To provide a power recovery system which reduces total energy consumption in an industrial processing process or a fluid-refining process including delivery of fluid under a high pressure. SOLUTION: The power recovery system is provided with a high-pressure pump 5, a reverse osmosis membrane cartridge 8, a positive-displacement piston pump 23, and a power-recovery pump turbine 18. The high-pressure pump 5 pressurizes supplied raw water, and the reverse osmosis membrane cartridge 8 produces processed water by performing membrane processing of high pressure water discharged from the high-pressure pump 5 by a reverse osmosis membrane 10. The positive-displacement piston pump 23 pressurizes the supplied raw water by making use of the pressure of the concentrated water which has been discharged from the reverse osmosis membrane cartridge 8 without being processed by the reverse osmosis membrane 10. The power-recovery pump turbine 18 increases the pressure of the pressurized water which has been pressurized by the positive-displacement piston pump 23, and makes the pressurized water merge with the high-pressure water discharged from the high-pressure pump 5. The pressurized water generated in the system is made a power source of the power-recovery pump turbine 18. COPYRIGHT: (C)2009,JPO&INPIT

摘要： PROBLEM TO BE SOLVED: To make automatic and smooth execution possible by a method wherein a mud discharge pump is controlled, based on a set flow rate for mud discharge, when shifting is made from a face holding operation mode to a bypass operation mode, while a set mud feed pressure is made to become of characteristic of nth power, being synchronized with the flow rate of mud discharge. SOLUTION: On shifting from a face holding operation mode to a bypass operation mode, a mud feed pump 4 is operated at its lowest speed and a mud discharge pump 3 is operated at its lowest speed. A mud feed pressure regulator 10 and a mud discharge flow rate regulator 12 take in the results of detection at the lowest speed outputted from sensors 9 and 11 and put the values of mud feed pressure and mud discharge flow rate into memories. Then, variation is made from the actual mud discharge flow rate to a final set value for mud discharge flow rate, and the mud discharge flow rate regulator controls operation of the mud discharge pump 3, based on the variation. At the same time, variation is made, being synchronized with the mud discharge pump 3, from the actual mud feed pressure to a final value for mud feed pressure on characteristics of nth power, and the mud feed pressure regulator 10 controls operation of the mud feed pump 4.
