Abstract
The present invention pertains to the field of jet technology and essentially relates to a pumping-ejection apparatus including a vacuum-producing device. Further, the apparatus is equipped with a condenser, a jet pump and an additional vacuum-producing device which has a boosting liquid-gas ejector, an outlet separator, an additional pump and an additional condenser. The evacuated medium inlet of the jet pump is connected to the separator, the outlet of the jet pump is connected to the suction side of the pump, the inlet of the jet pump for motive medium is connected to the discharge side of the pump. The inlet of the condenser is connected to the ejector's outlet, outlet of the condenser is connected to the separator. The gas inlet of the boosting ejector is connected to the pipe for discharge of compressed gas, the outlet of the boosting ejector is connected to the inlet of the additional condenser. The outlet separator is connected to the outlet of the additional condenser and to the suction side of the additional pump. The introduced pumping-ejection apparatus exhibits an increased operational reliability.
