    An electrostatic pump comprises a body having upstream and downstream chambers insulated from each other, and joined by constricted channel, adjacent the upstream mouth of which is the sharp conductive tip of an injection electrode. The channel around the conductive tip is shaped to promote laminar non-turbulent liquid flow past the tip, under the influence of a high potential difference between the injection electrode and a discharge electrode in the downstream chamber.

    The invention relates to pump construction -I relates to electrostatic pumps for pumping weakly conducting liquids.
    The purpose of the invention is to reduce current losses in liquids having a resistivity in the range of 10 to 10 ohm-cm and to ensure more reliable pumping.

The pump comprises a tubular body 1 of durable insulating plastic (for example, nylon or polyacetal) with a diameter of about 2 mm. The upper (in the direction of flow through the pump at the time of application) end 2 of the housing 1 is made with a ring having an internal thread to install the injection electrode 3. The latter is made in the shape of a cylinder 4 with an external thread terminating at the lower end with a cone 5 (apex angle 36 °) whose end 6 is pointed. At the upper end of the injection electrode 3, there is a groove 7 for tightening the electrode in the ring and changing its position. On the threaded cylindrical surface of the electrode, two diametrically opposite grooves 8 (Fig. 2) are formed, which function as channels for supplying fluid into the housing. The housing 1 is made with an inner sleeve 9 dividing the housing into the upper 10 and lower 11 chambers. The sleeve 9 is made in one piece with the housing 1 and has a central conical part 12, into which the cone 5 of the injection electrode 3 is inserted. In the center of the sleeve 9 there is a cylindrical channel 13 with a diameter of 0.2 mm and a length of 0.2 mm, for the passage of fluid from the top 10 to the lower 1I chamber,

    The invention relates to a pump engineering industry, and relates to electrostatic pumps for pumping weakly conducting liquids. The purpose of the invention is to reduce current losses in liquids having a specific resistance in the range of 1010 ohm-cm and to ensure more reliable pumping. FIG. 1. given the proposed pump, axial section; in fig. 2 shows section A-A in FIG. one; in fig. 3 is a graph of pump pressure versus distance between the working end of the injection electrode and the cylindrical part of the channel; in fig. 4 shows an embodiment of the injection electrode. The pump comprises a tubular body 1 of durable insulating plastic (for example, nylon or polyacetal) with a diameter of about 2 mm. The upper (in the direction of flow through the pump at the time of application) end 2 of the housing 1 is made with a ring having an internal thread to install the injection electrode 3. The latter is made in the shape of a cylinder 4 with an external thread terminating at the lower end with a cone 5 (apex angle 36 °) whose end 6 is pointed. At the upper end of the injection electrode 3, there is a groove 7 for tightening the electrode in the ring and changing its position. On the threaded cylindrical surface of the electrode, two diametrically opposite grooves 8 (Fig. 2) are formed, which function as channels for supplying fluid into the housing. The housing 1 is made with an inner sleeve 9 dividing the housing into the upper 10 and lower 11 chambers. The sleeve 9 is made in one piece with the housing 1 and has a central conical part 12 into which the cone 5 of the injection electrode 3 is inserted. The shape and size of the conical part corresponds to the shape and size of the cone electrode except for the apex of the conical part, the angle of which is somewhat larger (40). In the center of the sleeve 9 there is a cylindrical channel 13 with a diameter of 0.2 mm and a length of 0.2 mm, for the passage of fluid from the upper 10 to the lower 1I chamber. In the lower chamber 11 there is a sleeve 14 made of insulating plastic, forming a housing for the metal core of the sleeve 15, which is removed from the output of channel 13 and is discharged by a discharge elec- tro of the genus; by means of electrical connections, electrodes 3 and 15 are connected by a source of high voltage. The pressure developed by the pump depends on the size of the pump, the applied voltage, the properties of the pumped liquid (the degassed liquid works better), but most of all from the position of the working end 6 of the injection electrode 3. FIG. Figure 3 shows a plot of the back distance (axial displacement of the working end of the electrode back from the cylindrical part of the channel 13) versus pressure for pumps of this type. When using a liquid with a specific resistance of 4.4–10, with an applied voltage of 17 kV and a diameter of the cylindrical part of the channel of 0.35–0.895 mm, a static pressure of approximately 1 m of water column was obtained. The maximum head is obtained when shifted back by about 0.11, 0 mm. The injection electrode 3 is usually made of metal. FIG. Figure 4 shows a variant of the electrode, which is a strong plastic body (for example, made of polyacetal) 16 of the specified form, metallized on all sides with a thin metal layer 17 (thickness less than μm), for example aluminum or copper. Such electrodes do not need metal grinding, but can be made by injection molding followed by vacuum metallization. In operation, a liquid (e.g., an indenticide solution in an organic solvent, having a viscosity of 8 cSt and a resistivity of 1.10 0 m-cm at 25 s) is introduced into chambers 10 and P through grooves 8. When the electric power is turned on, a voltage drop occurs between Kondom 6 injection an electrode and a liquid in chamber 11. The ions are introduced from end 6, are attracted through channel 13 to chamber I, and ultimately are discharged on electrode 15.-This provides a steady pumping effect. Fluid in channel 13 acts as B iicoKoe resistance, limiting the current between the electrodes. Claims 1. Electrostatic pump for liquids containing ICH1
