    摘要： The leak detection appliance has a test inlet to which a test chamber containing the test specimen can be connected. A high-vacuum pump produces a high vacuum in a test gas detector. A preliminary vacuum pump contains two pump stages. In order to evacuate the test chamber, the pump stages are operated in parallel mode, with their suction capabilities being added. When the necessary vacuum has been achieved, the pump stages are operated in series in order to produce the necessary high vacuum—which is required for high detection sensitivity—on the test gas detector.

    摘要： A compression machine includes a refrigerant condenser, an expansion device, a refrigerant evaporator, a first compressor and a second compressor. Each compressor is arranged to receive lower pressure refrigerant vapor from the evaporator and to deliver higher pressure vapor to the condenser independently of the other compressor. The first compressor operates when the compression machine is operating in a first duty mode, for example a water-cooling mode. The second compressor operates when the compression machine is operating in a second duty mode, for example one of a water-heating mode or a brine cooling. The first compressor is selected for optimal performance in the first duty only and the second compressor is selected for optimal performance in the second duty mode only.

    摘要： A system and a method for adding and subtracting stages of compression to a compressor as and when the compressor requires them. If the compressor needs only a low pressure ratio, then the system and method allow the compressor to operate with only a primary pumping circuit spinning, while available additional stages, forming a secondary pumping circuit, and which may be required at other times when the needed pressure ratios increase, are decoupled from the rotating shaft, so that the compressor pumps at its most efficient and flexible point. Further, a system and method for adding and subtracting stages of compression to a compressor in order to increase and decrease the pumping capacity as and when required to satisfy a given load requirement.
