где QH - инжектируемый расход воды из колодца;
Qp - расход основного потока воды на входе в струйный аппарат;
dr - диаметр диффузора;
dc - диаметр рабочего сопла;
Рр - давление на входе основного потока воды в струйный аппарат;
РH - давление на входе инжектируемого потока воды в струйный аппарат,
причем водоподъемный насос имеет технические характеристики, обеспечивающие подачу, не превышающую величину расчетного дебита колодца, и напор не менее
где
∑hw1 - суммарные потери напора в вертикальной трубе и трубах сборного водовода;
∑hw2 - суммарные потери напора в струйных аппаратах,
на вертикальной напорной трубе под динамическим уровнем воды расположен датчик, воспринимающий давление внутри этой трубы и снаружи, выходы которого подсоединены к входам блока управления, у которого выходы подсоединены к пусковому устройству насоса и приводу задвижки на сборном водоводе, за которой по отношению к насосу, установлен датчик, воспринимающий давление внутри водовода, выход которого также подключен к входу блока управления.A device for extracting water from a group of mine wells, comprising a prefabricated water conduit and a water-lifting pump, characterized in that the water-lifting pump, located in one of the wells under a dynamic water level, is connected by a vertical pressure pipe to a collection water pipe, on which it is connected to vertical pipes at its junctions , lowered under dynamic water levels in other wells, are jet devices, the structural dimensions of each of which are determined from the condition
where Q H is the injected water flow from the well;
Q p is the flow rate of the main water stream at the inlet to the jet apparatus;
d r is the diameter of the diffuser;
d c is the diameter of the working nozzle;
R p - pressure at the inlet of the main stream of water in the jet apparatus;
P H is the pressure at the inlet of the injected stream of water into the jet apparatus,
moreover, the water-lifting pump has technical characteristics that ensure a flow that does not exceed the value of the calculated flow rate of the well, and a pressure of at least
Where
∑h w1 - total pressure loss in the vertical pipe and the pipes of the collection pipe;
∑h w2 - total pressure loss in jet devices,
on the vertical pressure pipe under the dynamic water level there is a sensor that senses the pressure inside this pipe and outside, the outputs of which are connected to the inputs of the control unit, whose outputs are connected to the pump starting device and the valve actuator on a prefabricated water conduit, behind which, with respect to the pump, is installed a sensor that senses the pressure inside the conduit, the output of which is also connected to the input of the control unit.
