A submersible gate pump

Abstract

The invention discloses a submersible gate pump, which comprises a gate and a through-flow submersible pump. One end of the gate is provided with a water inlet flange, and the other end of the gate is provided with a water outlet flange. The flange and the outlet flange are connected inside the gate through a sealing cylinder. A positioning ring is fixed on the outer circumference of the water inlet of the tubular submersible pump, and a guiding cone is provided on the front end of the positioning ring. The water inlet end of the tubular submersible pump is provided with a compression flange, and the compression flange is fixed on the water inlet flange of the gate by bolts. There is a taper that matches the guide cone of the positioning ring, and the slope on the inner hole of the rear end face of the compression flange is offset against the guide cone of the positioning ring, changing the assembly of the traditional through-flow submersible pump and the gate into a double-end support , effectively change the unfavorable factors such as unit vibration and submersible pump flange deformation, and improve the safety and reliability of the unit operation.

Description

technical field [0001] The invention belongs to the technical field of tubular submersible pumps, in particular to a submersible gate pump. Background technique [0002] Tubular submersible pump is an updated product of the traditional tubular pump unit, which can be immersed in water for a long time and is widely used in industrial mines, docks, agricultural production, urban water supply and drainage, water supply engineering, power station water supply and drainage and other fields. [0003] The combination of the tubular submersible pump and the gate to form the tubular submersible gate pump is the key technology of the integrated pump gate station. In the past, most of the tubular submersible pumps and gates were fixedly connected with the gate by a flange at one end, and the other end was suspended in the air. Pump cantilever installation (see attached Image 6 ), poor stability is likely to cause unit vibration, equipment fatigue damage, affect the safe use of equipme...
