Background
At present, most of brine guiding water in the salt field is operated by a mixed flow pump, and the normal clearance between an impeller and a pump cover is 1mm-2.5mm in order to achieve the service efficiency of the mixed flow pump in the operation process. The salt pan brine mixing pump has the advantages that the salt pan brine mixing pump is poor in mining conditions, normal abrasion of the bearing easily causes friction between the impeller and the pump cover, the service life of the impeller and the service life of the pump cover are shortened, and the use cost of the salt pan brine mixing pump of an enterprise is increased.
SUMMERY OF THE UTILITY MODEL
To the defect among the prior art, the utility model provides a mixed flow pump cover to solve the technical problem who proposes in the background art.
A mixed flow pump cover comprises a cover body, wherein a water inlet is formed in the middle of the cover body, a wear-resistant ring is fixedly arranged on a mounting surface of the cover body, which is in contact with a pump body, the wear-resistant ring is detachably connected with the cover body, the wear-resistant ring and the water inlet are concentrically arranged, and the wear-resistant ring and the surface of the cover body are hermetically arranged;
the material of wear-resisting circle is different with the material of impeller.
Further, the wear-resistant ring is fixedly arranged on the cover body through a positioning pin;
the locating pin is provided with a plurality ofly, and is a plurality ofly the locating pin evenly distributed is in on the wear-resisting circle.
Further, a mounting groove is formed in the mounting surface of the cover body, which is in contact with the pump body, and the wear-resistant ring is mounted in the mounting groove.
Further, the wear-resisting ring and the surface of the cover body are sealed through an O-shaped ring.
Furthermore, a concentric sealing groove is formed in the wear-resistant ring, and the O-shaped ring is arranged in the sealing groove.
The beneficial effects of the utility model are embodied in:
the wear-resisting ring is made of other metal materials except cast iron materials, for example, the wear-resisting ring can be made of metal materials such as aluminum, copper or stainless steel, friction resistance is small when the impeller and the wear-resisting ring are in surface contact, and the abrasion speed of the impeller can be effectively reduced. After the wear-resisting ring is worn and torn, only need to change wear-resisting ring can, can prolong the life-span of the impeller of pump and pump cover more than 3 times to wear-resisting ring cost only has 30% of pump cover cost, and the change time is 20% of pump cover change time, practices thrift the labor cost.
Drawings
In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the drawings used in the embodiments or the technical solutions in the prior art will be briefly described below. Throughout the drawings, like elements or portions are generally identified by like reference numerals. In the drawings, elements or portions are not necessarily drawn to scale.
Fig. 1 is a schematic structural view of a pump cover of a mixed flow pump provided by an embodiment of the present invention;
wherein, lid 1, inlet opening 2, wear-resisting circle 3, locating pin 4, O type circle 5.
Detailed Description
Embodiments of the present invention will be described in detail below with reference to the accompanying drawings. The following examples are only used to illustrate the technical solutions of the present invention more clearly, and therefore are only used as examples, and the protection scope of the present invention is not limited thereby.
It is to be noted that unless otherwise specified, technical or scientific terms used herein shall have the ordinary meaning as understood by those skilled in the art to which the present invention belongs.
As shown in fig. 1, the utility model provides a pair of mixed flow pump cover, including lid 1, 1 middle part of lid is provided with inlet opening 2, still fixedly on the installation face of lid 1 and pump body contact being provided with wear-resisting circle 3, wear-resisting circle 3 can be dismantled with lid 1 and be connected, and wear-resisting circle 3 sets up with inlet opening 2 is concentric, and wear-resisting circle 3 sets up with 1 surface seal of lid to, the material of wear-resisting circle 3 is different with the material of impeller.
Specifically, the mounting surface of the cover body 1 contacting with the pump body is provided with a mounting groove, and the wear-resistant ring 3 is mounted in the mounting groove. Wear-resisting circle 3 passes through locating pin 4 fixed mounting on lid 1, and locating pin 4 is provided with a plurality ofly, and a plurality of locating pins 4 evenly distributed are on wear-resisting circle 3. When changing wear-resisting circle 3, can change after taking off locating pin 4, make things convenient for the workman to operate, practice thrift wear-resisting 3 change times of circle.
The abrasion-resistant ring 3 and the surface of the cover body 1 are sealed through an O-shaped ring 5. A concentric sealing groove is formed in the wear-resistant ring 3, and an O-shaped ring 5 is arranged in the sealing groove. The O-shaped ring 5 can adopt a polyethylene sealing ring or a PTFE sealing ring.
The impeller and the pump cover of the pump are made of cast iron materials, and the friction coefficient is large when the impeller and the pump cover are contacted by the same material and small when different materials are contacted by the same material through tests. Therefore, in this embodiment, the wear-resistant ring is made of a metal material other than a cast iron material, for example, the wear-resistant ring may be made of a metal material such as aluminum, copper, or stainless steel, and the friction resistance is small when the impeller and the wear-resistant ring are in surface contact, so that the wear speed of the impeller can be effectively reduced. After the wear-resisting ring is worn, only need to change wear-resisting ring can, can prolong the life-span of the impeller of pump and pump cover more than 3 times to wear-resisting ring's cost only has 30% of pump cover cost, and the change time is 20% of pump cover change time, practices thrift the labor cost.
Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit the same; although the present invention has been described in detail with reference to the foregoing embodiments, it should be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; such modifications and substitutions do not depart from the spirit and scope of the embodiments of the present invention, and they should be construed as being included in the scope of the claims and description of the present invention.
