Abstract
The utility model relates to a multi-stage immersion centrifugal pump, which belongs to the technical field of industrial pump. The centrifugal pump has the important point that the utility model is provided with a balancing drum with amaze type sealing. One end of the balancing drum is provided with a maze sealing cavity, and inside of the amaze sealing cavity is provided with a throttle sleeve. The internal and external walls of the amaze sealing cavity on the balancing drum and the internal and external walls of the throttle sleeve are all provided with spiral grooves. The utility model is characterized by good sealing effect, which reduces environment polluting and has good spreading and application value.
Description
The utility model relates to multistage submerged centrifugal pump structure, belongs to the industrial pump technical field.
Existing multi-level submerged pump, constitute by pump case, pump shaft, impeller, balancing drum, bearing, sealing etc., be widely used in industrial fields such as oil, chemical industry, this pump is because the gap between balancing drum and the pump case, medium directly enters the balancing drum top, very big to the sealing influence, thereby leak seriously befouling environment.
The purpose of this utility model is to provide a kind of good seal, the multistage submerged centrifugal pump of long service life by the improvement to existing Under Water Pumps.
The purpose of this utility model is to realize that by the improvement to existing multi-level submerged pump multistage submerged centrifugal pump comprises pump case, pump shaft, impeller, bearing, sealing, it is characterized in that centrifugal pump is provided with band labyrinth sealed balancing drum.One end of balancing drum is provided with the labyrinth seal chamber, and orifice sleeve is set in the chamber, and orifice sleeve is fixedly connected on the pump case, and the inside and outside wall in labyrinth seal chamber is provided with spiral chute, and the inside and outside wall of orifice sleeve is provided with the reverse acting spiral groove.When multistage submerged centrifugal pump is worked, the medium that gap between balancing drum and pump case enters, must just enter into capping through several turnovers, adding has spiral chute to disturb entering of medium on the way, so the pressure when medium arrives capping descends greatly, the safety that helps sealing improves the effect of sealing, prolongs the working life of sealing.
The utility model novel and reasonable structure is manufactured easily, and the Packed again effect of the function of the existing balancing axial thrust of balancing drum has improved the sealing effect of pump, reduces and leaks and environmental pollution, and the excellent popularization using value is arranged.
Accompanying drawing 1 is a structural representation of the present utility model, 1 pump case, 2 pump shafts, 3 balancing drums, 4 sealings, 5 orifice sleeves among the figure.
Accompanying drawing 2 is a balancing drum structural representation of the present utility model, 6 spiral chutes among the figure.
Accompanying drawing 3 is an orifice sleeve structural representation of the present utility model, 7 spiral chutes among the figure.
Narrate case study on implementation of the present utility model below in conjunction with accompanying drawing.
The end towards seal arrangement at balancing drum is provided with the labyrinth seal chamber, on the inside and outside wall in labyrinth seal chamber spiral chute is set.In the labyrinth seal chamber orifice sleeve is set, on the inside and outside wall of orifice sleeve the reverse acting spiral groove is set, orifice sleeve is fixedly connected on the pump case.
