(54) ЭЛЕКТРОСТАТИЧЕСКИЙ НАСОС(54) ELECTROSTATIC PUMP

Изобретение относитс к насосо- строению,а именно к электрическим насосам дл перекачки жидкостей и газов и может быть применено в электронной , химической и других отрасл х промьшшенности дл перекачки и создани напора жидких и газообразных . сред..The invention relates to pump construction, namely to electric pumps for pumping liquids and gases, and can be applied in electronic, chemical and other industries for pumping and creating liquid and gaseous pressure. av ..

Известен мембранный насос дл диэлектрических сред, содержащий диэлектрический канал, в котором перпендикул рно оси насоса расположены пол рно неподвижные электроды с одинаково малой кривизной поверхности и электрод-мембрана, размещенный мелзду неподвижными электродами. Все электроды снабжены перепускными клапанами гп.A diaphragm pump for dielectric media is known, which contains a dielectric channel in which perpendicular to the pump axis there are polarly fixed electrodes with equally small curvature of the surface and an electrode-membrane placed along the pool with fixed electrodes. All electrodes are equipped with bypass valves gp.

Недостатком этого насоса вл етс невозможность перекачки электропроводных и даже слабопровод щих рабочих сред, поскольку сам принцип работы насоса предопредел ет надежную изол цию между электродами,The disadvantage of this pump is the impossibility of transferring electrically conductive and even weakly conducting working media, since the very principle of operation of the pump determines reliable insulation between the electrodes,

Известен также электростатический насос, содержащий рабочий канал с вз1рД1Л1м и выходньгм торцами, снабженными перепускными клапанами и диэлектрический патрубок, расположенный перпендикул рно оси канала, в котором размещены неподвижный и подвижный электроды,причем подвижный электрод укреплен на дне диэлектрического сильфона,а внутренн поверхность An electrostatic pump is also known, which contains a working channel with vp1rD1L1m and outlet ends equipped with bypass valves and a dielectric branch pipe located perpendicular to the channel axis, in which a fixed and movable electrodes are placed, the movable electrode being mounted on the bottom of the dielectric bellows, and the inner surface

10 диэлектирического патрубка выполнена с развитой поверхностью Г21.10 dielectric nozzle is made with a developed surface G21.

В известром насосе подвижный электрод вьшолнен Ъ виде провод щего диска и соединен с источником пита15 ни гибким проводником. Ниличие отдельного источника питани подйижного Электрода и средства подачи этого питани на электрод усложн ют систему питани насоса и снижают на20 дежность его рабрты.In a well-known pump, the movable electrode is made in the form of a conducting disk and is connected to the source of power by a flexible conductor. The presence of a separate power source of the sub electrode and the means for supplying this power to the electrode complicate the power supply system of the pump and reduce the efficiency of its operation.

Claims

The purpose of the invention is to simplify the power system and increase the reliability of the pump. The goal is achieved by the fact that in an electrostatic pump containing a working channel with inlet and outlet ends equipped with relief valves and a dielectric nozzle located perpendicular to the axis of the channel in which the stationary and movable electrodes are placed, the movable electrode being mounted on the bottom of the dielectric - bellows, and the inner surface of the dielectric nozzle is made with a developed surface, the movable electrode is made in the form of a unipolar electrolyte. In order to increase the manufacturer's capacity, the pump is additionally equipped with a second channel installed parallel to the first, both channels connected by the above-mentioned dielectric port, in the middle of which is installed. the stationary electrode, and electrets of opposite polarity are placed on both sides of the dielectric sylphs, in addition, the stationary electrode is equipped with a hole and a dielectric gate of the hole, the dielectric socket is filled with invert gas. The drawing shows the proposed pump with two working channels / option. The electric pump consists of two working channels 1, at the ends of which are located the bypass valves 2, and the dielectric nozzle 3, in which the fixed electrode 4 and the movable electret electrodes 5 on the dielectric bellows 6 are located. The stationary electrode is provided with a hole 7 and a dielectric gate 8, which regulates the magnitude of the latter. The pump works as follows. The fixed electrode 4 is supplied with a high voltage of a certain polarity. Under the action of electrostatic interaction forces, the electret of the same polarity repels itself from the stationary electrode, and the opposite one is attracted to it. Dielectric electrodes 6 provide for free movement of the electret electrodes. The unidirectional movement of the pumped medium is created by the system bypass valve. 2. A hole 7 in the stationary electrode 4 allows the air to move freely during the reciprocating motion of the moving electrodes / s .5. The implementation of mobile electrodes in the form of electrets eliminates the need for an additional high-voltage power source, which simplifies the power system and increases the reliability of the pump as a whole. The use of inert gas eliminates the disadvantage of all devices with electrets. In the air, for example, there is always some. A new amount of free ions of both polarities that are attracted to them by the action of the field of electrets of the corresponding polarity, thereby reducing the intensity of the external field of the electrets. Inert gas ionization energy; great, there are practically no free ions in them. Consequently, in the inert gas atmosphere there is no weakening of the strength of the electret field. The presence of a dielectric damper allows you to adjust the size of the hole in the stationary electrode and thus, changing the gas-dynamic resistance to the movement of the inverted gas when the pump is running, smoothly adjust its power.
