HEAT HYDRAULIC PLANT Russian patent published in 2003 - IPC

FIELD: heat power supply systems. SUBSTANCE: invention can be used to supply separate consumers from renewable sources. Proposed hydraulic plant contains drive motor with vertical shaft and rotary converter arranged in liquid-filled tank and coupled with electric machine. Vertical shaft is mechanically coupled with hydraulic pump and with low conicity ferromagnetic rotor placed inside gauge pressure container secured inside tank and partially filled with magnetic liquid and communicating with outlet branch pipe of hydraulic pump installed for submerging inlet branch pipe into magnetic liquid. Side walls of container and rotor are made in form of surfaces conjugated with clearance, with spiral channels on rotor surface, and side walls of container are formed by pole shoes of field winding with circular non-through groove between poles closed on permanent magnet from outside of container which is furnished with reducing return valve to provide circulation of magnetic liquid at preset pressure between consumer and hydraulic plant. Moreover, shaft is mechanically coupled with rotor through overrunning clutch furnished with pulley of belt drive to motor- generator connected to said fields winding and to local power circuit. EFFECT: reduced overall dimensions, increased efficiency of heat transfer to consumer. 3 cl, 1 dwg
