摘要： A power generation apparatus that suppress cavitation includes a first on/off valve provided between a steam generator and an expander in a circulating channel; a bypass channel connected between an area between the steam generator and the first on/off valve and an area between the expander and a condenser; a second on/off valve provided in the bypass channel; a third on/off valve provided between a pump and the steam generator; and a controller. When stopping the pump, the controller outputs a control signal that stops the pump, a control signal that closes the first on/off valve, a control signal that opens the second on/off valve, and a control signal that closes the third on/off valve. In the case where a predetermined condition has been met, the controller outputs a control signal that closes the second on/off valve.

摘要： In a power generation apparatus, a working medium is evaporated in an evaporator using a heating medium supplied from outside, and the evaporated working medium is subsequently introduced into an expander, which is connected to an electric generator, to convert a thermal expansion force of the working medium into a rotation force inside the expander for generation of electric power. Then, the working medium exhausted from the expander is fed into a condenser in which the working medium is condensed by cooling the working medium with a coolant medium supplied from outside, and the condensed working medium is pressurized by a circulating pump to resupply the evaporator with the pressurized working medium. In the power generation apparatus, when a condensing pressure in the condenser is high, a rotational speed of the circulating pump and a suction volume of the evaporator are increased.

摘要： A screw vacuum pump which includes a pair of screw rotors meshing each other with a small gap defined therebetween. A closing valve is provided in an oil circulation line leading from an oil stripper to a rotor chamber accommodating the screw rotors. A pressure switch for detecting a suction pressure is connected to the closing valve. When the suction pressure is lower than a predetermined value (i.e., at high level of vacuum), the closing valve is opened to supply the oil into the rotor chamber.
