Description

(54) MEMBRANE INLETER

I

The invention relates to pump engineering and can be used in various sectors of the national economy, mainly for injecting gaseous media.

A membrane blower is known, which contains at least one pump chamber separated from the drive chamber by a membrane on which an electric discharge electrode is fixed, coaxial to the second electrode 1.

However, this blower has one working chamber, and since the membrane deflection is limited by its elastic properties, the working volume of the blower, specific power, pressure and other specific indicators are limited, which does not allow full use of the electro-hydraulic capabilities. drive.

The purpose of the invention is to increase the specific indicators of the supercharger.

To achieve this goal, the supercharger is additionally equipped with a second pump chamber and a membrane on which the second electrode is mounted, with the second

The pump chamber is separated by an additional membrane from the drive chamber.

The proposed supercharger shown in the drawing.

Claims (1)

In case 1, two pump chambers 2 and 3 are made, separated by membranes 4 and 5 from drive 6. On membranes 4 and 5, on the side of the drive chamber 6, electrodes 7 and 8 of the electric discharge coaxially are mounted. Electrodes 7 and 8 are included in the power supply circuit of the electric discharge (not shown), which is connected to terminals 9. The drive chamber 6 is connected by a valve 10 to an additional tank 11. In housing 1, an intermediate chamber 13 is bounded by an elastic membrane 12, which communicates with the pump chamber 2 through the discharge valve 14 and with the pump chamber 3 through the channel 15 and the suction valve 16. The pump chamber 2 is also equipped with a suction valve 17 communicated with the suction nozzle 18, and the pump chamber 3 is equipped with a discharge valve 19, with a discharge pipe 20. Diaphragm blower works as follows. Opening the valve 10, the drive chamber 6 is filled with the drive fluid from the tank 11. Gaseous products are also removed from the valve 10 through the valve 10. After filling the chamber 6, the electrodes 7 and 8 are at a minimum distance from each other, which is determined by the volume of the driving fluid in the chamber 6. The electrodes 7 and 8 are supplied with a voltage sufficient to break down the established interelectrode gap. An electrohydraulic discharge occurs in chamber 6, as a result of which the pressure rises in it and membranes 4 and 5 bend in opposite directions. At the same time, the volume of chambers 2 and 3 is reduced, the gaseous medium being pumped from the pump chamber 2 flows through the discharge valve 14 into the intermediate chamber 13, and from the pump chamber 3 through the discharge valve 19 - into the discharge pipe 20 and further to the consumer. The membrane 12, when it enters the chamber 13 of the pumped medium, is arched. During this period, the distance between the electrodes 7 and 8 increases and the voltage applied to them does not provide breakdown of the interelectrode gap. After the completion of the injection cycle, the vapors of the drive fluid in chamber 6 condense, the pressure in the latter drops and membranes 2 and 3 return to their original position, moving towards each other. The pumped medium from the suction inlet 18 flows through the suction valve 12 into the expanding pump chamber 2, and from the intermediate chamber 13 under the action of overpressure created by the elasticity of the membrane 12 to the expanding pump chamber 3, the passage through the channel 15 and the suction valve 16. it provides the highest pressure at the entrance to the pump chamber 3 of the second pump stage. After the membranes 4 and 5 return to their original position, at which the distance between the electrodes 7 and 8 is minimal, the voltage on the latter becomes sufficient for the breakdown of the interelectrode gap and a new electro-hydraulic discharge occurs. Next, the operation cycle repeats. By providing stepwise pumping of the pumped medium from one drive chamber, a more complete utilization of the power of the electro-hydraulic discharge is achieved and the specific indicators of the supercharger are increased. Claims of invention on which the second electrode is installed, the second pumping chamber being separated by an additional membrane from the drive chamber.
