METHOD AND WATER-WORK FOR PRODUCING LAYER-WATERS THROUGH WATER-PRODUCING WELLS BY PUMP

摘要

In the process according to the invention, water is pumped from the natural underground reservoirs to the surface and the pumping is carried out in a manner that the depressive pressure is variably changed between two non-zero values by regulating the pumping capacity of the pump and / or the throttle of the well, and the direction and sign are kept unchanged. The control is carried out according to the change in the level of water in the surface water reservoir by increasing the pumping capacity of the pump and reducing the throttle level if the water level decreases the supply capacity of the water pump and the level of throttle is increased if the water level rises above a second set value. The process is carried out by means of a waterworks comprising at least one water-producing well, pump, control unit, and surface water reservoir, according to the invention, the control unit (8) being configured as a speed and / or throttle regulator and with level indicators (4) disposed in the reservoir (4). 5, 6) and on the outgoing side are connected to a pump and / or a throttle.
