Abstract:
The present invention relates to a vacuum pump for a high-altitude test and a chamber for a high-altitude test using the same and, more specifically, to a vacuum pump for a high-altitude test which controls an altitude rising rate inside a chamber for a high-altitude test by comprising an inverter to control the number of rotations of a motor in the vacuum pump; and to a chamber for a high-altitude test using the same. The vacuum pump for a high-altitude test controls an altitude rising rate inside a chamber, and comprises an inverter for controlling the number of revolutions of a motor. A chamber for a high-altitude test using the vacuum pump is controlled by the vacuum pump which uses the inverter to control the number of revolutions of a motor in order to control an altitude rising rate in the chamber.
Abstract:

Abstract:
PURPOSE: A jig for attaching and detaching a port plate is provided to reduce a work load because a worker does not need to lift up a port plate when the port plate is installed. CONSTITUTION: A jig for attaching and detaching a port plate comprises a support unit (100). The support unit is formed around the port of a chamber and supports a port plate (20) to the port of the chamber. The support unit comprises a pair of parallel supports (110) and horizontal supports (120). The parallel supports are formed in the chamber. The horizontal supports cross the parallel supports and support the port plate.
Abstract:
PURPOSE: A blower device for high-temperature or cryogenic gas is provided to accurately simulate a space environmental test of a satellite on the ground by circulating the high-temperature or cryogenic gas into a shroud. CONSTITUTION: A blower device for high-temperature or cryogenic gas comprises a blower case(101), a blower(110), a heat exchanger(130), and an airtight member(150). The blower is embedded in the blower case and supplies the high-temperature or cryogenic gas. The heat exchanger circulates heat exchange mediums to the internal space of the blower case to prevent the heating of a blower motor due to the gas supplied by the blower. The airtight member seals a driving shaft of the blower so that the driving shaft of the blower cannot come in contact with the gas supplied by the blower.
Abstract:
PURPOSE: A device and a method for sensing a leakage are provided to sense leakages generated in several spots of a target object simultaneously by sensing the leakages by using infrared rays. CONSTITUTION: A device(1) for sensing a leakage comprises a supply unit(10) and a sensing unit(20). The supply unit supplies a sensitizer to the inside of a target object. The sensing unit senses the existence of a leakage of the sensitizer from the target object by using infrared rays. The supply unit supplies the sensitizer to the inside of the target object after heating.
