Claims (2)

1. Устройство для очистки фильтров в скважинах, включающее трубопровод или колонну труб, эластичный баллон и прерыватель потока прокачиваемой жидкости, отличающееся тем, что прерыватель потока выполнен в виде автоколебательной системы, содержащей трубный корпус-цилиндр с боковыми отверстиями, соединенный с корпусом эластичного баллона; поршень, выполненный в виде стакана и помешенный в цилиндр на скользящей посадке, верхний торец которого нормально сомкнут с нижним торцом корпуса эластичного баллона; пружину, подпирающую поршень, и пробку, соединенную на резьбе с цилиндром для регулирования степени сжатия пружины.1. A device for cleaning filters in wells, including a pipeline or pipe string, an elastic balloon and an interrupter for the flow of pumped liquid, characterized in that the interrupter is made in the form of a self-oscillating system comprising a pipe cylinder body with side openings connected to an elastic cylinder body; a piston made in the form of a glass and placed in a cylinder on a sliding fit, the upper end of which is normally closed with the lower end of the body of the elastic cylinder; a spring supporting the piston, and a plug connected to the cylinder thread to control the compression ratio of the spring. 2. Устройство для очистки фильтров в скважинах, включающее трубопровод или колонну труб, эластичный баллон и прерыватель потока прокачиваемой жидкости, отличающееся тем, что эластичный баллон содержит трубный корпус с боковыми отверстиями, соединенный с колонной труб, облеченный снаружи эластичным кожухом, герметично закрепленным на концах корпуса и образующий с ним общую внутреннюю полость.2. A device for cleaning filters in wells, including a pipeline or pipe string, an elastic balloon and an interruption of the pumped fluid flow, characterized in that the elastic balloon comprises a pipe body with side openings connected to the pipe string, clad on the outside with an elastic casing sealed at the ends housing and forming with it a common internal cavity.
