Изобретение относитс к насосостроению , в частности к конструкции ; элёктроимпульсных насосов и может быть использовано при проектировании систем дл транспортировки жидкости 5 при повышенном давлении.The invention relates to pump engineering, in particular, to a structure; electropulse pumps and can be used in the design of systems for transporting fluid 5 at elevated pressure.

Известен элёктроимпульсный насос, содержащий рабочую камеру с нагнетательным клапаном-прерывателем,; систему электродов, св занных с источником питани и напорную емкость tU. .Known electropulse pump containing a working chamber with a discharge valve-interrupter ,; a system of electrodes associated with a power source and a pressure tank of tU. .

Недостатком известного насоса вл етс мала надежность, св за ина с наличием подвижных элементов,The disadvantage of the known pump is low reliability, due to the presence of moving elements,

Наиболее близким к изобретению по технической сущности и достигаемому результату вл етс электроимпульсный насос, содержащий рабочуй камеру с подводами рабочей жидкости и парабо лическим отргокателем, размещенные в ней электроды,Подключенные к источнику питани и имеющие оси, расположенные в плоскости, проход щей через фокус отражател , и сопло 2. 25The closest to the invention in technical essence and the achieved result is an electropulse pump containing a working chamber with supplying working fluid and a parabolic deflector, electrodes connected thereto, connected to a power source and having axes located in a plane passing through the focus of the reflector, and nozzle 2. 25

Недостатком известной конструкции вл етс низкий КИд и невысока надежность .A disadvantage of the known construction is low CID and low reliability.

Цель изобретени - увеличение КПД иНадёжности..30The purpose of the invention is to increase efficiency and reliability. 30

Поставленна цель достигаетс тем, что на внутренней поверхности стенки рабочей камеры выполнена цилиндрическа проточка, на выходе из сопла установлен датчик давлени , подключенный k источнику питани электродов, а подводы выполйены в виде тангенциальных каналов, располс кенных в зоне проточки.The goal is achieved by the fact that a cylindrical groove is made on the inner surface of the working chamber wall, a pressure sensor is installed at the nozzle outlet, connected to the k power supply of the electrodes, and the supply lines are made in the form of tangential channels located in the groove zone.

На фиг,1 схематически показан насос , продол ьйый разрез; на фиг.2 сечение по цилиндрической проточке,Fig. 1 shows a schematic of a pump, a prolonged section; Fig.2 section along a cylindrical groove,

Электроимпульснь1Й нйсос содержит рабочую камеру 1 с Подводами рабочей жидкости, выполненными в виде танген- .-.:.- 15 циальных каналов 2, и параболическим отражателем 3, размещенные в ней электроды 4, подключенные к источнику 5 питани и имеющие оси, проход щие через фокус б отражател 3, и соп ло 7f а на внутренней поверхности 8 стенки рабочей камеры 1 выполнена цилиндрическа проточка 9, и на выходе 10 из сопла 7 установлен датчик 11 давлени , подключенный к источнику 5 питани электродов 4,The electric pulse contains a working chamber 1 with supply of working fluid, made in the form of a tangent- .-.: .- 15 channels 2, and a parabolic reflector 3, electrodes 4 placed in it, connected to the power source 5 and having axes passing through the focus 6 of the reflector 3 and the nozzle 7f a cylindrical groove 9 are made on the inner surface 8 of the wall of the working chamber 1, and a pressure sensor 11 is connected at the outlet 10 of the nozzle 7 and connected to the power supply 5 of the electrodes 4,

Насос работает следующим образом.The pump works as follows.

При включении питани электродов 4 в фокусе 6 параболического отража тел 3 возникает быстр расшир юцийс When turning on the power of the electrodes 4 in the focus 6 of the parabolic reflection of the body 3, there is a rapid expansion of

Claims

781 399 a plasma bubble, creating a spherical Cheeks uzazarnuyu wave. A shock wave that propagates in the radial HW direction from the forkus 6 of a parabolic reflector 3, as well as a part of the vapnya reflected from the parabolic reflector 3, carries the fluid in the cavity The working chamber 1 of the pump to the outlet 10 of the nozzle 7. As a result, a vacuum is created in the cylindrical bore 9 and the liquid is sucked into the working chamber 1 through the tangential channels 2, creating a spiral, apr f around the nozzle 7 n ac. The next discharge of the main part of the energy goes into the shock wave propagating along the nozzle 7. A part of the shock wave that hits the cylindrical groove 9 affects the incoming flow, which has a moment of momentum due to the tangential inlet, which counteracts fluid outflow working chamber 1. In addition, this part of the shock wave is dispersed perpendicularly to the direction of movement of the swirling flow of liquid, which also prevents liquid from being ejected from the working chamber 1. The pressure sensor 11 indicates that at a moment rekrascheni fluid flow toward the outlet of the nozzle 7 is fed a voltage pulse to the electrodes 4. Thus the whole process is pbvtor. The design of the pump has no moving parts, therefore, the service life and reliability of the pump is increased. In addition, the design allows pumping a liquid with solid particles in it without reducing the efficiency of the pump, the invention Electric pulse pump containing a working chamber with supply of working fluid and a parabolic reflector, electrodes connected to the power source and having axes located in a plane passing through the focus of the reflector, and a nozzle, characterized in that, in order to increase efficiency and reliability, on the inner surface of the wall of the working chamber is made A small groove, a pressure sensor is installed at the nozzle outlet, connected to the source of electrodes, and the submersibles are made in the form of tangential kanaloses located in the groove zone.
