Изобретение относитс к насосостроению , касаетс объемных насосов и может найти применение в различных отрасл х народного хоз йства дл перекачк текучих сред под высоким давлением.This invention relates to a pump engineering industry, is concerned with positive displacement pumps and can be used in various sectors of the national economy for pumping fluids under high pressure.

Известен объемный насос, содержащий рабочую камеру с параболиче;ской стенкой, снабженную каналами дл подвода и отвода жидкости.,. последний из которых расположен против параболической стенки корпуса по оси параболоида , проход щей через его фокус, и устройство дл создани в фокусе параболоида зоны интенсивного испарени жидкости 1.A volumetric pump is known that contains a working chamber with a parabolic wall, provided with channels for supplying and discharging liquid.,. the latter of which is located against the parabolic wall of the body along the axis of the paraboloid passing through its focus, and the device for creating in the focus of the paraboloid a zone of intense evaporation of the liquid 1.

Недостаток насоса заключаетс в том, что интенсивное испарение жидкости обеспечиваетс электрораэр дом в жидкости, при котором возникают значительные (до 50%) потери энергии на излучение в ударной волне, что приводит к существенному снижению КПД насоса.The disadvantage of the pump is that the intense evaporation of the liquid is provided by the electric heater in the liquid, which causes significant (up to 50%) energy loss due to radiation in the shock wave, which leads to a significant decrease in pump efficiency.

На фиг.1 представлен насос без фокусирующей линзы; на фиг.2 - то же, с фокусирующей линзой.Figure 1 shows a pump without a focusing lens; figure 2 - the same, with a focusing lens.

В корпусе 1 насоса выполнена рабоча камера 2 с параболической стен15 кой 3. Рабоча камера 2 имеет отделенную диафрагмой 4 насосную полость 5 и снабжена сообщенными с насосной полостью 5 каналами подвода 6 и отвода 7 перекачиваемой жидкости, в кото20 рых установлены, соответственно, всасывающие В и нагнетательный .9 клапаны . Канал 7 расположен против параболической стенки 3 по оси параболрида, проход щей через его фокус.

Устройство дл создани в фокусе параболоида зоны интенсивного In the pump casing 1, a working chamber 2 with a parabolic wall 3 is made. The working chamber 2 has a pumping cavity 5 separated by a diaphragm 4 and provided with channels 6 and outlet 7 of the pumped liquid communicated with the pumping cavity 5, in which delivery .9 valves. Channel 7 is located against the parabolic wall 3 along the axis of the parabolride passing through its focus. In the parabolic wall 3 of the housing 1. Along the axis of the aboloid, a window J.O is made of a material that is transparent to quantum radiation. A device for creating an intense zone at the focus of a paraboloid

Claims

30 liquid evaporation is made in the form of a quantum generator 11 mounted against the window 10 on the outer side of the housing 1. A focusing lens 12 can be mounted between the quantum generator 11 and the focus of the paraboloid 3. When the quantum generator 11 is turned on, it is connected. evaporates a beam of electromagnetic radiation of a certain wavelength, the choice of which depends on the type of fluid. The radiation time is determined by the required pump flow, the radiation power is the power required to sample the liquid and form a plasma. The radiation beam of the quantum generator 11 is focused at the focus of the parabolic wall 3, either by appropriately selecting the power level of the corresponding self-focusing beam, or by the focusing lens 12. In the focus of the parabolic wall 3, a high-temperature plasma is formed and an intense evaporation of the liquid occurs. the starting moment forms a shock wave with a steep front, which, when propagated, practically does not cause the liquid to move in the working chamber 2. Then, due to evaporation audio ,, liquid is formed Vågå vapor bubble with high internal giving leniem which expands Referring to the relatively low velocity fluid moves layers. The parabolic wall 3 reflects the moving fluid layers and forms a specific movement of the fluid towards the diaphragm 4. Lastly, it sags, displaces the pumped medium from the pumping cavity 5 to the discharge channel 7. The damper 13 smoothes the sharp increase in pressure in the working chamber

2. After the end of the action of the quantum radiation pulse, the pressure and temperature decrease in the vapor bubble due to its expansion and on reaching the critical state the vapor condenses. The pressure in the working chamber 2 drops and the diaphragm 4 returns to the dry position, ensuring the suction of the pumped liquid into the pump cavity 5. Then the cycle repeats. The use of a quantum generator 11 for evaporating a fluid increases the pump's efficiency, since the loss of breakdown of the fluid is reduced, its heating is eliminated due to the passage of electrical current through the breakdown channel in the fluid, and the heat loss due to radiation in the shock wave is reduced, Radiation power, thus choosing the optimal mode. In addition, the design of the pump is simplified by eliminating the high voltage generator and increases electrical safety. Claim 1. A volumetric pump containing a working chamber with a parabolic wall, provided with channels for supplying and discharging liquid, the latter of which is located against the parabolic wall of the housing along the axis of the paraboloid passing through its focus, and a device for creating an intense evaporation zone at the focus of the paraboloid liquid, characterized in that, in order to increase the efficiency in the parabolic wall of the housing, a window made of a transparent for the quantum radiation material is made along the axis of the paraboloid, and a device for evaporating The awn is made in the form of a quantum generator installed on the outside of the case against the window. 2, The pump according to claim 1, wherein a focusing lens is installed between the focus of the paraboloid and the quantum generator, whose focus coincides with the focus of the paraboloid.
