Abstract
The invention discloses a water-ring vacuum pump, and relates to the technical field of vacuum pumps. The water-ring vacuum pump comprises an impeller, a pump body and a pump cover; the impeller is arranged in the pump body, and at least one end of the pump body is connected with the pump cover; two sides of the pump cover are respectively provided with an air inlet and an air outlet; and the central axis of the impeller is deviated from the transverse and longitudinal center lines of the cross section of the pump body. The water-ring vacuum pump solves the problem that a conventional water-ring vacuum pump is not ideal in air exhaust capability.
Description
Technical field
The present invention relates to vacuum pump technology field, particularly relate to a kind of water ring vaccum pump.
Background technique
Two center lines being in length and breadth centrally disposed on pump housing cross section of the impeller of traditional water ring vaccum pump are wherein on one, and offset certain distance with pump housing central point, thus changed from small to big again from large to small in the space between impeller hub to water ring, thus the function that realization is bled and is vented.
As shown in Figure 1, it is the sectional view of traditional water ring vaccum pump, it comprises impeller 1, the pump housing 2, pump cover, impeller 1 is located in the pump housing 2, the pump housing 2 at least one end is ined succession pump cover, the both sides of pump cover are respectively equipped with suction port 3 and relief opening 4, and the center of impeller 1 is wherein on of two center lines in length and breadth of the pump housing 2 cross section.
Because the center of traditional vacuum pump impeller is wherein on of two center lines in length and breadth of pump housing cross section, the wheel hub of impeller is large not to the space between water ring, causes the exhaust capacity of vacuum pump not ideal enough.
Summary of the invention
The object of the invention is to propose a kind of water ring vaccum pump, the exhaust capacity of this water ring vaccum pump can be made comparatively strong, and operational efficiency is higher.
For reaching this object, the present invention by the following technical solutions:
A kind of water ring vaccum pump, it comprises impeller, the pump housing, pump cover, and described impeller is located in the pump housing, and the pump housing at least one end is ined succession pump cover, the both sides of described pump cover are respectively equipped with suction port and relief opening, and the horizontal and vertical center line of the central axis of described impeller and the cross section of the pump housing all departs from.
Concrete, described suction port and relief opening are located at the top of pump cover, and the central axis of described impeller is located at the top of the cross central line of the cross section of the pump housing.
Beneficial effect of the present invention has:
The horizontal and vertical center line of the central axis of the impeller of water ring vaccum pump of the present invention and the cross section of the pump housing all departs from, thus increases the space between the wheel hub of impeller and water ring, makes exhaust capacity stronger.
Accompanying drawing explanation
Fig. 1 is the sectional view of traditional water ring vaccum pump;
Fig. 2 is the sectional view of the water ring vaccum pump that the embodiment of the present invention provides;
In figure, 1, impeller; 2, the pump housing; 3, suction port; 4, relief opening; 5, water ring.
Embodiment
Technological scheme of the present invention is further illustrated by embodiment below in conjunction with accompanying drawing.
As shown in Figure 2, be the water ring vaccum pump that provides of the embodiment of the present invention sectional view, it comprises impeller 1, the pump housing 2, pump cover, impeller 1 is located in the pump housing 2, the pump housing 2 at least one end is ined succession pump cover, and the both sides of pump cover are respectively equipped with suction port 3 and relief opening 4, and the horizontal and vertical center line of the central axis of impeller 1 and the cross section of the pump housing 2 all departs from, thus the space between the wheel hub of impeller 1 and water ring 5 is increased, make the exhaust capacity of water ring vaccum pump stronger.
As shown in Figure 2, the suction port 3 of water ring vaccum pump provided by the invention and relief opening 4 are located at the top of pump cover, and the central axis of described impeller 1 is located at the top of the cross central line of the cross section of the pump housing 2, are convenient to suck and Exhaust Gas.
Obviously, the above embodiment of the present invention is only used to clearly demonstrate example of the present invention, and is not the restriction to embodiments of the present invention.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here exhaustive without the need to also giving all mode of executions.All any amendments done within the spirit and principles in the present invention, equivalent to replace and improvement etc., within the protection domain that all should be included in the claims in the present invention.
