Abstract
The utility model discloses a vacuum pump. The vacuum pump comprises a circular shell, an impeller, blades, an inlet pipe, an outlet pipe and connection sheets, wherein the impeller is mounted in the shell; the circle center of the circular impeller is located on one side of the circle center of the shell; the impeller is connected with the blades; the inlet pipe and the outlet pipe are connected to the top of the shell. As the working pressure range of the vacuum pump is large, the vacuum pump can be applied to various occasions with high requirements and has high efficiency; meanwhile, as having a simple rotor structure, the vacuum pump is convenient to check and maintain.
Description
Technical field
The utility model relates to a kind of vacuum pump, belongs to field of mechanical technique.
Background technique
Existing vacuum pump, concentric type if, its advantage had is that rotor has good geometrical symmetry, therefore vibrate little, smooth running, but this pump work pressure is little, efficiency is lower, effectively in the time, is being difficult to the work that vacuumizes that the amount of finishing the work is larger.Centrifugal vacuum pumps for some, its rotor surface is the curve cylinder that shape is comparatively complicated, processing and check more difficult.
The model utility content
The utility model provides a kind of vacuum pump, can change the above defect, and its range of working pressure is larger, can be applied to multiple occasion of having relatively high expectations, and efficiency is high, and simultaneously, its rotor structure is simple, is convenient to inspection and maintenance.
For solving above technical problem, the utility model provides following technological scheme: a kind of vacuum pump, comprise housing, impeller, blade, inlet tube, outer pipe and connecting sheet, described housing is circular shell, and impeller is installed in housing, and described impeller is also circular, the side of its center of circle in the housing center of circle, described impeller connects blade; Described inlet tube and outer pipe all are connected in the top of housing.
Further, the quantity of described blade is at least 12.
Further, the profile of described blade is cuboid, is plate shape.
Further, described blade tie point corresponding with impeller place tangent line angle is 30 °-60 °.
This vacuum pump that the utility model relates to, simple in structure, high working efficiency, simple in structure, be convenient to maintenance.
The accompanying drawing explanation
Fig. 1 is the utility model vacuum pump sectional view;
The side view that Fig. 2 is Fig. 1.
Embodiment
As depicted in figs. 1 and 2, comprise housing 1, impeller 2, blade 3, inlet tube 4, outer pipe 5 and connecting sheet 6, housing 1 is circular shell, and impeller 2 is installed in housing 1, and impeller 2 is also circular, the side of its center of circle in the housing center of circle, impeller 2 connects blade 3; Inlet tube 4 and outer pipe 5 all are connected in the top of housing 1.
The quantity of blade 3 is at least 12.
The profile of blade 3 is cuboid, is plate shape.
Embodiment described in the utility model does not form the restriction to the application's scope; every within the spirit and principle of the utility model design, any modification that one of skill in the art can make, be equal to and replace and within improvement etc. all should be included in protection domain of the present utility model.
