Fig. 1 is a schematic structural diagram of the present invention.
Detailed Description
The following description is provided for illustrative purposes, and other advantages and features of the present invention will become apparent to those skilled in the art from the following detailed description.
The utility model provides a centrifugal pump anti-blocking device, as shown in figure 1.
This stifled device of centrifugal pump anti-sticking, including the pump body 1, pump cover 2 and impeller 3, pump cover 2 seals fixes in one side of the pump body 1, and forms pump chamber 4 of installation impeller 3 between pump cover 2 and the pump body 1, the interval is equipped with a plurality of inlet tube 5 that is used for washing on the pump cover 2, and the mouth of pipe of inlet tube 5 lays towards impeller 3. The pump cover comprises a pump cover body and is characterized by further comprising a suspension 6 and a rotating shaft 7, wherein the suspension 6 is fixed on one side of the pump cover 2, the rotating shaft 7 is supported in the suspension 6 through a bearing, and one end of the rotating shaft 7 extends into the pump cavity 4 and is fixedly connected with the impeller 3.
In the use, the quantity of inlet tube 5 is selected according to the size of centrifugal pump, and in this embodiment, inlet tube 5 is equipped with 2 along vertical interval distribution, and the head end and the water source of inlet tube 5 are connected, and the during operation adopts normal water pressure to wash and can satisfy the demand.
The anti-blocking device of the centrifugal pump is suitable for all products of centrifugal pumps, and the water inlet pipe 3 on the pump cover 2 can be composed of 1 or more than one according to the size of the centrifugal pump. When the impeller 3 rotates in operation, the blades of the impeller 3 promote the medium to rotate rapidly, the medium in the pump is thrown out from the center of the impeller 3 under the action of centrifugal force, a vacuum area is formed in the center of the impeller 3, and the medium forms continuous pumping under the action of atmospheric pressure; due to the complexity of media, the media are gathered after entering the main impeller or the auxiliary impeller, and finally the load of the pump is increased, or the main impeller and the auxiliary impeller are stuck and abraded too fast, and the plurality of water inlet pipes at the pump cover 2 are filled with flushing water to flush the interior of the pump, so that the media, impurities and the like gathered at the impeller 3 and the pump cover 2 or the lining plate are flushed away, the gathering of media impurities is avoided, and the load, abrasion and blocking phenomena of the pump are reduced.
The foregoing shows and describes the general principles, essential features, and advantages of the invention. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, but rather is described in the embodiments and descriptions herein to illustrate the principles of the invention and that various changes and modifications may be made without departing from the spirit and scope of the invention, all of which fall within the scope of the claimed invention. The scope of the invention is defined by the appended claims and equivalents.
In the description of the present invention, it should be understood that the terms "front", "back", "left", "right", "center", etc. indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, and are only for convenience of description and simplicity of description, and do not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and thus should not be construed as limiting the scope of the present invention.
