pump engineering. SUBSTANCE: jet pumping plant has working chamber, nozzle mounted for axial motion and coupled hydraulically with power pump, and diaphragm positioned between nozzle and working chamber coaxially with them, with formation of two radial circular channels. One of channels provided between working chamber and diaphragm communicates with receiving channel of pumped-over medium. The second radial circular channel located between diaphragm and nozzle is coupled hydraulically with power pump and output line of working chamber through shut-off valve. EFFECT: enhanced reliability, simplified design. 1 dwg
