PULSE JET PUMPING APPARATUS

摘要

The invention relates to the manufacturing of pumps, compressors and vacuum machines and is used for the transportation (displacement) of gases, liquids and mixtures thereof. Disclosed is a pulse jet pumping apparatus which includes a body containing an internal working chamber, whereby a vaned rotor is mounted on an axis inside said chamber; a diffuser mounted downstream of a tangential outlet from the working chamber; a jet and an input nozzle oriented towards the center of the vaned rotor. An additional nozzle is mounted between the diffuser and a tangential output from the working chamber. An additional chamber is mounted between the working chamber and the input nozzle, coaxially with the latter, said additional chamber having the form of the solid of revolution; the diameter of any cross section of the additional chamber is less or equal to the diameter of the vaned rotor, whereby the jet is mounted tangentially to the surface of the additional chamber and communicates with the latter. The input nozzle comprises a diffuser section located within the cavity of the additional chamber. The diffuser output communicates with the input of the gas and liquid separator, said separator comprising respective outputs for gases and for liquids, whereby the output for liquids communicates with the nozzle input.
