Description

The invention relates to a positive displacement pump with an injection chamber equipped with two electrodes used to create spark discharges causing pressure pulses in the injected fluid.

In a known pump of the same principle, liquid is not prevented from being thrown from the discharge chamber into the feed channel.

In order to eliminate this drawback in the proposed pump, the supply channel is composed of several channels connected in series with each other at 90 ° angles.

FIG. Figures 1 and 2 depict a pump in two mutually perpendicular sections; in fig. 3 is an electrical circuit for switching on the pump.

The pump consists of a housing / and a receiver 2, equipped with a damper for equalizing the pulsating pressure of the liquid, the airbag of which is enclosed in a rubber casing 3. The discharge chamber 4 is in communication with the cavity

the receiver window, which can be blocked by a spring-loaded non-return valve 5. To enhance the movement of the fluid towards the receiver, the wall of the chamber 4, opposite the valve 5, is hemispherical.

In case I, two electrodes 9 and 10 are reinforced with textolite insulators 5 and 7 and bushings 8. The negative electrode Yu is grounded and provided with a disk // at the end protruding into the injection chamber 4.

The receiving channel for supplying the injected fluid into the chamber 4 is composed of several channels 12, 13, 14 and 15 connected between themselves at 90 ° angles. The channels are provided with dead ends to more effectively prevent the discharge of fluid from the injection chamber 4 under the action of pressure pulses. The liquid is supplied to the channels 12, 13, 14 and 15 through the pipeline 16 at atmospheric pressure, and it is discharged through the pipeline 17 under high pressure, which occurs in the pressure chamber 4 as a result of spark discharges obtained at the electrodes 9 and 10. Discharged from the liquid, during spark discharges, air bubbles are discharged from chamber 4 through the outlet port to the receiver. In the case of the pump operating in an inverted position, when the chamber 4 is located with its outlet window to the side or downward, air bubbles are discharged through the inlet channel 16.

The electrodes 9 n JO are connected to the high-voltage transformer IS through additional spark gaps J9 and 20, which form the main spark discharge on electrodes 9 and 10.

The pump capacity and the pressure of the injected fluid are controlled by varying the voltage and capacitance of the electrical discharge circuit, as well as by changing the length of the spark gap between the electrodes 9 10 and spark gaps 19 and 20.
