The invention relates to constructions of pumps-generators, which can be used in Autonomous closed heating systems icheskih systems Closest technological solution is rotary pump-heat (patent RU 2159901), containing a hollow body with a suction inlet for supplying a heated liquid. Inside the housing is a rotor in the form of a double-flow centrifugal wheel with the holes on the periphery. Concentric with the rotor is a stator with holes. The holes in the rotor is made in the form kropiewnicki nasdaw Venturi, and the holes in the stator is in the form of suddenly expanding nasdaw.The disadvantages of the known device is that the liquid is not sufficiently heated in a single pass through the pump-heat. To raise the temperature of the liquid required multiple pumping through pump-heat.Technical problem on which the invention is directed, is the creation of a device, through which the treated liquid is repeatedly subjected to the pressures on it, resulting in intense heating of the liquid in one pass through hydroshock pump-heat.The problem is solved in that in a rotary hydraulic shock pump-heat, which has a full body with a suction nozzle for supplying a heated fluid and a discharge pipe for exhaust heated liquid, and located inside the housing is in the form of a tapering nozzle, in the annular channel from the side of the rotor and stator installed perforated cavities, within which is placed an elastic hollow balls, and rings made with holes in them in the form of a tapering nozzle, the interior annular channel, and the base of the nozzles supplying heated liquid and outlet are located in the annular channel.Fig 1 shows a section of a rotary hydraulic shock pump-boiler, consisting of the following main parts: 1 - hollow body; 2 - nozzle for supplying a heated liquid; 3 - tube for removal of the heated liquid; 4 - ring stator with holes; 5 - pump rotor-generator; 6 - drive shaft; 7 - ring rotor with holes; 8 - seal stator; 9 - seal rotor.In Fig.2 shows the node I when the movement of hydroporn of the holes of the rotor in the bore of the stator In Fig.3 shows the node I when the movement of hydroporn from the hole of the stator into the hole of the rotor.In Fig.4 shows a plot of the magnitude of the ratio of the weight of the blowyfrom the corner extensionsnozzles of the rotor and stator, which shows that the most advantageous angle of expansion is within 6-8o. When e is p>Works as described rotary hydraulic shock pump-heat follows.When the shaft 6 (Fig.1) of the heated fluid through inlet pipe 2 of the hollow body 1 is supplied to the ring of the rotor 7, the liquid fills the holes of the rotor 7 and the annular channel between the ring of the rotor 7 fixed to the rotor 5, and the ring of the stator, and then the holes in the ring of the stator.Under the action of centrifugal force the liquid inside the nozzle hole of the rotor is discharged into the annular channel between the rings of the rotor and the stator, and when combined holes rushes in coplowe hole of the stator. When fluid flow in Solovay hole of the stator deformation of a hollow sphere 15 under the action of hydraulic shock 11 (Fig.2). To prevent flow of fluid in the torque hydraulic blow hole 10 of the housing 1 and the bore of the stator is sealed with a gasket 8 and the holes of the rotor similarly sealed with a gasket 9.Liquid ejected from the nozzles of the rotor under the action of the kinetic energy forms in the nozzle of the rotor of the hydraulic piston 12 with the formation of a zone of discharge 13. In the closed volume of zone 13, occurs under the action of reduced pressure, the saturation of the liquid in pairs, obrazovanja ejection of the liquid from the nozzle hole of the stator, under the action of energy of a hollow sphere 15, which, taking the original form, according to fluid kinetic energy. As in the hole of the rotor was a vacuum, the liquid from the nozzle holes of the stator rushes into the holes of the rotor. A sharp increase in pressure in the zone of hydraulic shock 14 forces you to condense vapors of the liquid and cavitation bubbles, and the kinetic energy of the fluid deforms the hollow ball 16 in the hole of the rotor.When filled with liquid vacuum zones 13 of the rotor and stator at the time of vapor condensation liquid is a sharp decrease in volume. It is known that the volume of condensate in the 400-1500 times smaller than the amount of steam equal to him in the mass.Pressure resulting from the condensation of vapor-gas and cavitation bubbles can be identified by the formulas: 1. The closure of the gas and steam bubbles:where R30is the radius of the initial values of the gas bubble, mm; R3- the final value of the gas bubble, mm; P0- hydrostatic pressure in the liquid, kg/cm2; P is the pressure arising in the Central condensation of the cavitation bubble, kg/cm2.For example: whenand P0
wherethe compressibility of the fluid, kg/cm2(water=5010-6kg/cm2).For the same value of P0=1 kg/cm2andget P=10300 kg/cm2.P0=10 kg/cm2andget P=498800 kg/cm2.The above values of pressures occur when condensation was cavitation bubbles. In the moving fluid, and even more so when the condensation of the bubbles in the hydraulic conditions of shock deformation of their surface and shape change.When condensation deformed cavitation bubbles occur, the cumulative streams, pressure which may exceed the pressure from condensation perfect bubbles up to a dozen times. Given the changes in the volume of steam by condensation (400-1500) and values
R0we can assume that the pressure P can be much larger than when
Local increase of the temperature of the heated liquid from the pressure differential arising from hydraulic ugalde V - fluid volume, cm3;
P - differential pressure kg/cm2;
V is the volumetric weight of the fluid, kg/cm3;
C - specific heat of liquid, kcal/kgo;
m - mechanical equivalent of heat, kgcm3/kcal;
t is the temperature rise of the liquid,oC.Water: V-0.001 kg/cm3;
With - 1.0 kcal/kgo;
m - 42700 kg cm3/kcal;
when R0= 10 kg/cm2pressure dropR will be
P=498800 - 10=498790 kg/cm2.In this case, thet=0,0234P=0,0234498790=11671,69oC.Similar processes of vaporization and condensation, water hammer and cavitation occur in the nozzles of the rotor and stator repeatedly with increasing pressure from a suction pipe 2 to the pipe 3. The heated fluid through a discharge pipe is routed to a destination.In order to reduce friction losses in the nozzles, and therefore, reduce pressure and prevent separation of the jet from the walls of the nozzle angle of expansion should be within 6-8o.Regulation is about to install energy-efficient heating mode liquid.The level of metal in modern machine-building enterprises makes it possible to manufacture a rotary hydraulic shock pumps-generators on the basis of commercially available sand, soil and other pumps that have a significant radius of the impeller and its height
The specified pump-generator can be used for heating and hot water supply objects that are distant from the power supply units, as well as for heating of process fluids.Similar sources of heat required in areas requiring preservation of clean environment and safety in places of its development (hospitals, rest homes, and so on)
