Abstract
A self-suction centrifugal pump is characterized by comprising a vacuum pump fixed at the upper end of the centrifugal pump, wherein the vacuum pump is communicated and connected with a vacuum starting control part through a vacuum hose, the vacuum starting control part is communicated and connected with an inlet of the centrifugal pump, a floating ball valve switch is arranged on the vacuum starting control part, a cavity provided with an impeller is communicated and connected with a volute, the volute is communicated and connected with a discharge part, and the discharge part is connected with a non-return mechanism.
Description
Technical Field
The utility model relates to a from inhaling formula centrifugal pump belongs to pump equipment field.
Background
At present, the centrifugal pump needs a long time to normally operate when extracting liquid, so that the efficiency is low, and the damage rate of the centrifugal pump is increased.
Disclosure of Invention
In order to solve the defects and shortcomings, the utility model provides a self-suction centrifugal pump.
The utility model discloses a solve the technical scheme that technical problem adopted as follows:
a self-suction centrifugal pump is characterized by comprising a vacuum pump fixed at the upper end of the centrifugal pump, wherein the vacuum pump is communicated and connected with a vacuum starting control part through a vacuum hose, the vacuum starting control part is communicated and connected with an inlet of the centrifugal pump, a floating ball valve switch is arranged on the vacuum starting control part, a cavity provided with an impeller is communicated and connected with a volute, the volute is communicated and connected with a discharge part, and the discharge part is connected with a non-return mechanism.
The utility model discloses the beneficial effect who reaches is: the pumping time of the centrifugal pump is greatly shortened, the working efficiency of the centrifugal pump is improved, and the damage rate of the centrifugal pump is reduced.
Drawings
The accompanying drawings are included to provide a further understanding of the invention, and are incorporated in and constitute a part of this specification, illustrate embodiments of the invention, and together with the description serve to explain the invention and not to limit the invention. In the drawings:
fig. 1 is a schematic structural view of the present invention.
Detailed Description
The technical solution of the present invention will be described clearly and completely with reference to the accompanying drawings, and obviously, the described embodiments are some, but not all embodiments of the present invention. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
In the description of the present invention, it should be noted that the terms "upper", "lower", "horizontal", "inner", "outer", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and simplification of description, but do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus, should not be construed as limiting the present invention.
In the description of the present invention, it is to be noted that, unless otherwise explicitly specified or limited, the terms "mounted," "connected," and "connected" are to be construed broadly, and may be, for example, fixedly connected, detachably connected, or integrally connected; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meaning of the above terms in the present invention can be understood in specific cases to those skilled in the art.
Furthermore, the technical features mentioned in the different embodiments of the invention described below can be combined with each other as long as they do not conflict with each other.
Example 1
As shown in figure 1, the self-priming centrifugal pump comprises a vacuum pump 1 fixed at the upper end of a centrifugal pump 2, the vacuum pump 1 is communicated and connected with a vacuum starting control part 4 through a vacuum hose 3, the vacuum starting control part 4 is communicated and connected with an inlet 5 of the centrifugal pump 2, the vacuum starting control part 4 is provided with a floating ball valve switch, a cavity provided with an impeller 6 is communicated and connected with a volute 7, the volute 7 is communicated and connected with a discharge part 8, and the discharge part 8 is connected with a non-return mechanism 9.
The working principle is as follows: the centrifugal pump 2 works to enable liquid to enter from the inlet 5, the vacuum pump 1 works to suck air above the inlet rapidly and enable the liquid to flow into the centrifugal pump 2 more rapidly, when the liquid of the vacuum starting control part 4 rises to a certain height, the floating ball valve switch closes the vacuum starting control part 4, the vacuum pump 1 stops working at the moment, when the liquid of the vacuum starting control part 4 is insufficient, the floating ball valve switch enables the vacuum starting control part 4 to be in an open state due to self gravity, the vacuum pump 1 starts working to accelerate the liquid to enter; the liquid then passes through the impeller 6 to the volute 7 and is discharged from the discharge portion 8, and the non-return mechanism 9 serves to prevent the discharged liquid from flowing back into the volute.
Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments described in the foregoing embodiments, or equivalents may be substituted for elements thereof. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
