steam jet vacuum pump
structure
Ejector (nozzle + sucking ventricular + diffuser)+ condenser + Steam System + Cooling-water System + vacuum line system + Measurement and Control System
working principle of Ejector:
In Figure 1, 1. steam inlet pipe, 2. Nozzle, 3. Sucking ventricular, 4. Physical mode of supersonic air flow sucking gases pumped, 5. Mixed Flow (pressure- boosted by diffusing pipe throat after two flows are mixed and their pressure is equalized). The diffusing pipe is composed of a convergent cone, a throat pipe and a divergent cone, in which the two flows mix.
A. inlet of working steam B. suction inlet of gases pumped C. mixed gases outlet
