Abstract

The utility model provides a protective structure of a water pump bearing end cover, which comprises a bearing body and a bearing end cover, wherein the rear end of the bearing body is provided with a first annular recess and a first annular protrusion, the front end of the bearing end cover is provided with a second annular protrusion and a second annular recess, the first annular protrusion is matched with the second annular recess in size, the first annular recess and the second annular protrusion have an interval, the rear end of the bearing end cover is provided with a ring groove, the ring groove is positioned at the inner side of the bearing end cover, a framework oil seal is arranged in the ring groove, and the framework oil seal is arranged around the outer edge of a shaft; the utility model has the advantages that: the framework oil seal is arranged in the ring groove at the tail end of the bearing end cover, and the framework oil seal is tightly wrapped on the shaft when the pump runs, so that various foreign matters (such as water, dust and the like) in the environment where the pump is located are prevented from entering the bearing chamber, and the water pump bearing chamber is protected safely and reliably.

Description

Protection structure of water pump bearing end cover

Technical Field

The utility model relates to a centrifugal pump field especially relates to a protective structure of water pump bearing end cover.

Background

The supporting point of centrifugal pump shaft generally arranges on the bearing, and the bearing is buried underground in the bearing room, not only must consider bearing structure's rationality when the design, but also must compromise sealed and protection problem of bearing end cover department. The protective measures of the traditional centrifugal pump bearing chamber are generally simple and crude, so that most of water pumps can only be installed indoors for use (namely in a pump room), the structure limits the use occasions of the pumps and can only be used indoors or additionally adds protective measures to the pumps. When the project site does not have the conditions, the pump cannot be used or the service life is shortened.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a protective structure of water pump bearing end cover.

In order to realize the purpose, the technical scheme of the utility model is that:

the utility model provides a protective structure of water pump bearing end cover, its characterized in that, bearing body and bearing end cover that connect gradually around including, the rear end of bearing body is equipped with first annular sunken and first annular arch, first annular sunken and first annular arch connect gradually the setting by the inboard to the outside of bearing body, the front end of bearing end cover is equipped with the protruding and second annular sunken of second annular, the protruding and second annular of second annular is sunken to be connected gradually the setting by the inboard to the outside of bearing end cover, the protruding size with the second annular is sunken to cooperate, there is the interval in the first annular sunken and second annular arch, the rear end of bearing end cover is equipped with the ring channel, the ring channel is located the inboard of bearing end cover, be equipped with the skeleton oil blanket in the ring channel, the skeleton oil blanket encircles the outer fringe setting of axle.

The utility model has the advantages that: the framework oil seal is arranged in the ring groove at the tail end of the bearing end cover, and the framework oil seal is tightly wrapped on the shaft when the pump runs, so that various foreign matters (such as water, dust and the like) in the environment where the pump is located are prevented from entering the bearing chamber, and the water pump bearing chamber is protected safely and reliably.
