Abstract
Погружной лабиринтно-винтовой насос для перекачивания жидкостей, содержащий ротор, на наружной поверхности которого выполнены канавки вращающейся части насоса, и корпус, на внутренней аксиальной поверхности которого выполнены канавки невращающейся части насоса, а на торцевых поверхностях выполнены входной и выходной каналы, отличающийся тем, что на торцевой поверхности ротора со стороны входного канала выполнены лопатки, вход насоса соединен с периферийной полостью лопаток, которая соединена с чашеобразным отстойником посредством отверстий сброса посторонних примесей в корпусе насоса, причем дно отстойника имеет герметичное соединение с входной частью корпуса насоса между отверстием сброса посторонних примесей и отверстием, располагаемым на корпусе насоса как можно ближе к оси вращения ротора. A submersible labyrinth-screw pump for pumping liquids, comprising a rotor, on the outer surface of which grooves of the rotating part of the pump are made, and a housing, on the inner axial surface of which grooves of the non-rotating part of the pump are made, and on the end surfaces there are input and output channels, characterized in that blades are made on the end surface of the rotor from the inlet channel, the pump inlet is connected to the peripheral cavity of the blades, which is connected to the bowl-shaped sump by means of openings of the discharge of impurities in the pump casing, the bottom of the sump having a tight connection with the input part of the pump casing between the hole for the discharge of foreign impurities and the hole located on the pump casing as close as possible to the axis of rotation of the rotor.
