Granted: 2004-01-27
Abstract: FIELD: oil producing industry. SUBSTANCE: device is designed for use in hydraulic machine engineering, particularly, in well diaphragm pumps. Proposed pump contains housing, bushing with diaphragms fitted in seats of bushing and made in form of sector cylinders and consisting of carrying and sealing members. With pump operating, its eccentric shaft acts onto eccentric bushing which acts onto pressure bearings and the latter act onto knockout device which compresses the diaphragms. Carrying members are not subjected to deformation on end face surfaces, i.e. they operate as piston. Sealing members are subjected to deformation which sharply increases operation reliability of device. As carrying and sealing members of diaphragms are made in form of solids of revolution, labor input at their manufacture and at manufacture of device as a whole is considerably reduced.

Abstract: FIELD: three-phase pulse-width output voltage regulators. SUBSTANCE: output voltage is regulated by means of transistor switch installed at output of first diode bridge connected to like-polarity leads of matching transformer secondary windings; other diode bridge is connected to other like-polarity leads of these transformer windings, polar capacitors being connected across output terminals of both bridges. Stepless switching of current is ensured due to voltage across plates of rather high-value damping capacitor connected to output terminals of first bridge. To this end mentioned capacitor is changed over to mode of charge- discharge alternating at every switching interval with aid of two additional transistor switches of which one connects common cathodes of second-bridge diodes to common anodes of first-bridge diodes, and second transistor switch connects positive plate of damping capacitor to common anodes of second-bridge diodes.

Title: Method for treating well-proximate layer area
Inventor: SHIPULIN A V
IPC: E21B37/00
Filed: 2002-08-15
Granted: 2004-03-20
Abstract: FIELD: mining industry. SUBSTANCE: method includes equipping well with a T-pipe with quick-opening valves. T-pipe is connected to a tank through a valve. Previously all air is pumped out of the tank for creating limited vacuum volume. One of said valves has access to atmosphere. Well is connected to fluid container through a T-pipe with valves. Previously fluid is pumped into the well. When fluid moves in the well shaft from well-proximate layer area towards day surface, pressure is scoured while well hollow is abruptly opened. A valve is opened, through which well fluid under pressure fills the tank. Fluid hits inner tank wall and is reflected from it while creating pressure impulses in well-proximate layer area in form of damped standing wave, which creates repression-depression impulses. Depression pressure overfall is formed between well-proximate layer area and well hollow. During period of depression half-wave growth waste is removed from the well by means of pumping fluid into container. EFFECT: possible restoration of well operation for wells without tubing string by means of pump and hoisting equipment. 1 dwg
