Abstract.
In this article the possibility of using of vacuum airlift to execute bottom deepening construction
works are considered. The problem of optimization of exploitation regimes of such settings from the position
of power inputs minimization has been given. Outputinput ratio of vacuum airlift is depended of absolute
pressure vacuum= in its air separator in subject to condition of other parameters, which do not change. The
dependencies for determination of outputinput ratio of vacuum airlift from pressure in air separator, and
to find the optimal pressure having exploitation parameters have been suggested.
Keywords:
vacuum airlift, density, pulp,
power inputs, outputinput ratio.
