DEVICE FOR EXTRACTION OF WATER FROM GROUP OF SHAFT WELLS Russian patent published in 2002 - IPC

FIELD: water supply. SUBSTANCE: device has a collecting water conduit and a water-lifting pump located in one of the wells under the dynamic water level, connected to the collecting water conduit through a vertical pressure pipe, located on the collecting water conduit are the jet devices connected water conduit are the jet devices connected to the vertical suction pipes lowered under the dynamic water levels in the other wells. The structural dimensions of each jet device and the technical data of the water-lifting pump are determined from formulas. Positioned on the vertical pressure pipe under the dynamic water level is a transducer perceiving the pressure inside and outside this pipe, its outputs are connected to the inputs of the control unit, whose outputs are connected to the pump starting device and the drive of the gate valve on the collecting water conduit, installed behind which relative to the pump is a transducer perceiving the pressure inside the water conduit, whose output is also connected to the input of the control unit. EFFECT: enhanced reliability, prevented depletion of the water-bearing horizon, expanded conditions of use, reduced expenditures connected with construction and servicing. 1 dwg
