Abstract

FIELD: mud pumps. SUBSTANCE: mud pump is driven by submersible electric motor to which single-spindle pump is connected. Single-spindle pump is provided with preconnected disintegrator for crushing solid particles contained in mud. Single-spindle pump has fixed stator and submersible electric motor which is provided with shaft extending to either side. Connected to upper end of shaft is single-spindle pump; connected to lower end of shaft is disintegrator whose outlet is provided with intermediate member hydraulically connected with suction member of single-spindle pump. Hydraulic connection is made by at least one line or ring-shaped space which is concentric relative to axis of submersible electric motor. EFFECT: enhanced reliability.

Изобретение относится к шламовому насосу, образованному погружным электродвигателем, к которому присоединен одношпиндельный насос с предвключенным дезинтегратором для дробления твердых частиц, которые содержатся в подаваемых шламах и сделали бы невозможной эксплуатацию самостоятельного одношпиндельного насоса. Для этой цели предусмотрены одношпиндельный насос с неподвижным статором и погружной электродвигатель, который содержит выступающий в обе стороны вал. К верхнему концу вала присоединен одношпиндельный насос, а к нижнему - дезинтегратор, выход которого снабжен промежуточным элементом, гидравлически присоединенным к всасывающему элементу одношпиндельного насоса. Гидравлическое присоединение образовано по меньшей мере одной линией или кольцеобразным пространством, которое выполнено концентрично оси погружного электродвигателя.The invention relates to a slurry pump formed by a submersible electric motor, to which a single-spindle pump is connected with an upstream disintegrator for crushing the solid particles contained in the supplied sludge and would make it impossible to operate an independent single-spindle pump. For this purpose, a single-spindle pump with a fixed stator and a submersible motor, which contains a shaft protruding in both directions, are provided. A single-spindle pump is connected to the upper end of the shaft, and a disintegrator is connected to the lower end, the output of which is equipped with an intermediate element hydraulically connected to the suction element of the single-spindle pump. The hydraulic connection is formed by at least one line or annular space, which is made concentric with the axis of the submersible motor.
