SELF-ADJUSTING HYDRODYNAMIC HEATER OF LIQUID Russian patent published in 2008 - IPC F24J3/00 

FIELD: the invention refers to heating engineering and is assigned for heating liquids for various branches of the people's economy.

SUBSTANCE: the technical result is providing capability for work of the hydrodynamic heater in a broad diapason of changing parameters of feeding and forcing the liquid supplying by the pump on its input at a changing frequency of rotation of the shaft of the pump. The self-adjusting hydrodynamic heater of liquid has a cyclone 1 with a lid 2 on which a limiting ring 3 and an adjusting screw 4 are installed, a conic vortex generator 5 is fastened to the cyclone 1, a cylinder 6 having a braking arrangement 7 is connected to the conic vortex generator 5. A breaking chamber 8 with a socket 9 perpendicularly placed to the cylinder 6 is located below the breaking arrangement 7, a hollow closed topped cone 10 is fixed to the lid 2 of the cyclone 1 with the aid of the adjusting screw 4. The cone 10 enters with its large foundation in the limiting ring 3; from the side of the smaller foundation a funnel 11 with a socket 12 are put on the hollow closed topped cone 10. The socket 12 passes through the cylinder 6, the breaking arrangement 7 and a directing bushing 13 installed in the breaking chamber 8 and provided with a fixing screw 14; additionally the hydrodynamic heater has a self-adjusting system having a spring 15 placed in the socket 12 leaned with one extreme screw against the bead 16 formed in the place of joining of the socket 12 and the funnel 11 and the other extreme screw - against a washer 17 putted on a rod 18 which is motionlessly connected with one end to the bottom of the smaller foundation of the closed hollow topped cone 10 and on the other end having a threading and a nut 19 fixing the washer 17 on the rod 18; at that in the bottom of the larger foundation of the closed hollow topped cone 10 there is a beaker 20 in which there is a spring 21 leaning with one extreme coil against an adjusting nut 22 being on an adjusting screw 4 and with the other extreme coil leaning against a supporting bushing 23 leaning with its broad foundation against the bottom 24 of the beaker 20. and with its narrow foundation putted on the adjusting screw 4 with possibility displacement of the supporting bushing 23 along the adjusting screw 4 limited with a head 25 on the end.

EFFECT: provides working capability of the hydrodynamic heater of liquids.
