Abstract
The utility model discloses a rotary case pump with labyrinth groove structure on liquid collecting pipe, comprising a pump case, a charging and discharging pipe, a liquid collecting pipe and a rotor which consists of an outer cover (3) and an inner cover (1) welded together. The assembling part of the inner cover (1) and the liquid collecting pipe (2) is a step-shape labyrinth groove structure. The structure can prevent the liquid in the cavity of the rotor from flowing toward the entrance of the rotor for the working rotary case pump so as to improve the efficiency of the rotary case pump.
Description
Technical field
The utility model relates to a kind of equipment for liquid transportation, especially relates to a kind of rotary case pump that is used to carry liquid medium.
Background technique
Rotary case pump is applied in industries such as petrochemical industry, papermaking, generating mostly, such as occasions such as waste liquid conveying, high-pressure spraying, boiler feed waters.At present, in the assembling of rotary case pump parts, the main Spielpassung mounting type that adopts between liquid collecting pipe and the rotor inner cap, liquid medium enters from liquid inlet pipe, when arrival rotor inner cap enters the rotor flow channels, some liquid can flow through from the assemblage gap between liquid collecting pipe and the rotor inner cap, and the rotor intracavity liquid can flow to rotor inlet place, has influenced the working efficiency of rotary case pump.
Summary of the invention
The technical problems to be solved in the utility model provides a kind of rotor intracavity liquid that can reduce to the mobile rotary case pump of rotor inlet place.
Technical problem to be solved in the utility model is achieved by the following technical solution: it comprises pump case, liquid in-out pipe, liquid collecting pipe and rotor, rotor is welded by rotor enclosing cover and rotor inner cap, cooperates the installation place to adopt step type maze trough structure with liquid collecting pipe at the rotor inner cap.
The said structure that the utility model adopts makes rotary case pump when the execution work task, and can reduce the rotor intracavity liquid and flow to rotor inlet place, thus the working efficiency of raising rotary case pump.
Description of drawings
Below in conjunction with accompanying drawing the utility model is described further:
Figure 1 shows that structural representation of the present utility model
Figure 2 shows that the partial enlarged drawing at I place among Fig. 1
Embodiment
As shown in Figure 1, this kind adopts the rotary case pump of maze trough structure to comprise pump case, liquid in-out pipe, liquid collecting pipe and rotor on liquid collecting pipe, rotor is welded by rotor enclosing cover 3 and rotor inner cap 1, cooperates the installation place to adopt step type maze trough structure with liquid collecting pipe 2 at rotor inner cap 1.Step type maze trough structure on the liquid collecting pipe as shown in Figure 2.When rotary case pump execution work task, liquid medium enters from liquid inlet pipe, when arriving the rotor place, owing to adopted step type maze trough structure on the liquid collecting pipe, liquid is difficult to cooperate the installation place to flow through from rotor inner cap 1 with liquid collecting pipe 2, can only flow through from rotor flow channels 4.
Claims (1)
1, a kind of rotary case pump that on liquid collecting pipe, adopts the maze trough structure, comprise pump case, liquid in-out pipe, liquid collecting pipe and rotor, rotor is welded by rotor enclosing cover and rotor inner cap, it is characterized in that: cooperate the installation place to adopt step type maze trough structure with liquid collecting pipe at the rotor inner cap.
