Abstract
The utility model discloses a water pump mechanical sealing device with a water throwing groove, which comprises the water throwing groove processed on a rotating shaft and a water inlet, a water outlet and a water collecting groove arranged on a static flange, wherein the water inlet is positioned right above the rotating shaft, the water outlet is positioned right below the rotating shaft, one side of the water outlet is provided with a leakage point, and the water throwing groove and the water collecting groove form a relatively closed space. The utility model has the beneficial effects that: the shaft sleeve can regularly lead out overflowing cooling water or other liquid without being provided with a framework oil seal, so that the overflowing liquid is prevented from flowing everywhere, the dryness of a working occasion is kept, related electric equipment is protected, the requirement on environmental protection can be met, and the service life of mechanical seal is prolonged.
Description
Technical Field
The utility model relates to the field of mechanical sealing, in particular to a water pump mechanical sealing device with a water throwing groove.
Background
The cooling water seal of the single-end-face mechanical seal is always a pain point of the mechanical seal used on site: 1, the cooling water splashes around along with the rotation of the rotating shaft when the rotating shaft is not sealed; 2, the framework oil seal is used for sealing, the sealing aging of the framework oil seal is short, and the abrasion to the rotating shaft is caused.
SUMMERY OF THE UTILITY MODEL
The utility model aims to overcome the defects of the prior art and provide a water pump mechanical sealing device with a water throwing groove, which can regularly lead out overflowing cooling water or other liquid under the condition that a shaft sleeve is not required to be provided with a skeleton oil seal, prevent the overflowing liquid from flowing everywhere, keep the working occasion dry, protect related electrical equipment, meet the requirement of environmental protection and prolong the service life of the mechanical sealing.
In order to solve the technical problems, the utility model provides the following technical scheme:
the utility model provides a water pump mechanical sealing device with a water throwing groove, which comprises a rotating shaft, the water throwing groove processed on the rotating shaft and a water inlet, a water outlet and a water collecting groove arranged on a static flange, wherein the water inlet is positioned right above the rotating shaft, the water outlet is positioned right below the rotating shaft, one side of the water outlet is provided with a leakage point, and the water throwing groove and the water collecting groove form a relatively closed space.
As the preferable technical scheme of the mechanical sealing device of the water pump with the water throwing groove, the angle of the water throwing groove is related to the rotating direction of a pump shaft connected to a rotating shaft.
Compared with the prior art, the utility model has the following beneficial effects:
the utility model has the beneficial effects that: the shaft sleeve can regularly lead out overflowing cooling water or other liquid without being provided with a framework oil seal, so that the overflowing liquid is prevented from flowing everywhere, the dryness of a working occasion is kept, related electric equipment is protected, the requirement on environmental protection can be met, and the service life of mechanical seal is prolonged.
Drawings
The accompanying drawings, which are included to provide a further understanding of the utility model and are incorporated in and constitute a part of this specification, illustrate embodiments of the utility model and together with the description serve to explain the principles of the utility model and not to limit the utility model. In the drawings:

Detailed Description
The preferred embodiments of the present invention will be described in conjunction with the accompanying drawings, and it will be understood that they are described herein for the purpose of illustration and explanation and not limitation. Wherein like reference numerals refer to like parts throughout.
In addition, if a detailed description of the known art is not necessary to show the features of the present invention, it is omitted. It should be noted that the terms "front," "back," "left," "right," "upper" and "lower" used in the following description refer to directions in the drawings, and the terms "inner" and "outer" refer to directions toward and away from, respectively, the geometric center of a particular component.
Example 1
Referring to fig. 1, the utility model provides a mechanical seal device of a water pump with a water throwing groove, which comprises a rotating shaft 6, a water throwing groove 2 processed on the rotating shaft 6 and a water inlet 1, a water outlet 4 and a water collecting groove 3 arranged on a static flange 7, wherein the water inlet 1 is positioned right above the rotating shaft 6, the water outlet 4 is positioned right below the rotating shaft 6, one side of the water outlet 4 is provided with a leakage point 5, and the water throwing groove 2 and the water collecting groove 3 form a relatively closed space.
The angle of the water throwing groove 2 is related to the rotation direction of a pump shaft connected to the rotating shaft 6.
The mechanical seal cooling water inlet and outlet are vertically arranged, the water inlet 1 is arranged right above the mechanical seal cooling water inlet, the water outlet 4 is arranged right below the mechanical seal cooling water inlet, the water flow is controlled by the aid of the cut-off water inlet 1, the water throwing groove 2 and the water collecting groove 3 form a relatively closed space, the angle of the water throwing groove 2 is related to the rotating direction of the pump shaft, the water collecting groove 3 is thrown under the action of centrifugal force through the cooling water of the water throwing groove 2, the water outlet 4 right below the water throwing groove flows out, and liquid overflowing is prevented from flowing everywhere.
Through tests, the device has remarkable effect on mechanical sealing of pump shaft diameters of 25 to 80.
The utility model has the beneficial effects that: the shaft sleeve can regularly lead out overflowing cooling water or other liquid without being provided with a framework oil seal, so that the overflowing liquid is prevented from flowing everywhere, the dryness of a working occasion is kept, related electric equipment is protected, the requirement on environmental protection can be met, and the service life of mechanical seal is prolonged.
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 changes may be made in the embodiments and/or equivalents thereof without departing from the spirit and scope of the utility model. 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.
