Abstract

The utility model discloses a complete device for vacuuming of a million-kilowatt level thermal power and nuclear power condenser, which comprises a gas-water separator, a water ring vacuum pump, a nozzle, an ejecting pipe component, a heat exchanger and the like. The nozzle and the ejecting pipe component are arranged at two inlet ends of the water ring vacuum pump. A pump gas inlet pipe is communicated with the two inlet ends of the water ring vacuum pump, a gas suction pipe and the ejecting pipe component. A pump exhaust pipe is communicated with two outlet ends of the water ring vacuum pump and the gas-water separator. The heat exchanger is communicated with the gas-water separator through an inlet connecting pipe of the heat exchanger, and simultaneously communicated with the water ring vacuum pump through a circulating water supplying component. The combination of the ejecting pipe component and the nozzle effectively solves the problems that the operating gas quantity can be decreased and gas etching easily occurs under a high-vacuum condition.
