| 摘要 |
The invention relates to electric pumps for pumping gases, dielectric and conductive fluids and can be used in the chemical and electronic industries to create pressure in the electroconvective heat exchangers and electrohydrodynamic heat pipes.The electrostatic piston pump, according to the first embodiment, includes a cylindrical chamber of dielectric material (1), the input and output ends of which are equipped with bypasses, at the same time inside the chamber (1) is placed a hollow piston (4) in the form of a ball of electrically conductive material, electrodes in the form of net (2), convexly located in the direction of the piston (4), fixed to the ends of the chamber (1) by means of springs (5) and connected to a power supply (3), and on the walls of the chamber (1) are consecutively arranged annular acceleration electrodes (6), connected over one to the opposite poles of the source (3). The pump also includes a pipeline (7) with a valve, fixed to the outside of the chamber (1), and which connects the spaces formed by the ends of the chamber (1) and the electrodes (2).The pump, according to the second embodiment, includes a pipeline of dielectric material (7) with a valve, rigidly fixed to the ends of the chamber (1), coaxial to it, and which passes through a through hole formed in the piston (4), with the possibility of free movement of the piston (4) along the pipeline (7), at the same time at the ends of the pipeline (7) are made through holes. The pipeline (7) is made of fluoroplastic. |
