Regulation of vacuum in milking machines by unit with pressure reducing valve and assessment of its basic parameters.

摘要

A unit with the pressure reducing valve to control vacuum at the simultaneous control of vacuum pump operation was designed. No additional atmospheric air is needed to be sucked in for vacuum control. The vacuum pump is passed through only by air consumed by the milking machine, i.e., a considerably lower amount than with the classical control valve. The use of special control unit with the pressure reducing valve reduced the consumption of electric energy. Results of the theoretical analysis withthe subsequent experimental verification to choose the optimum parameters of the unit are tabulated and discussed.
