Description

Technical Field

[0001] The utility model relates to the field of advanced manufacturing and automation, and more specifically, to a combined canned motor pump that is convenient for transportation. Background Art

[0002] A canned motor pump is a leak-free pump formed by integrating a canned motor and a pump, mainly composed of components such as a pump body, an impeller, a stator, a rotor, front and rear bearings, and a thrust disk. The stator and the rotor are respectively isolated by non-magnetic corrosion-resistant thin-walled sleeves. The rotor is supported by the front and rear bearings and immersed in the conveying medium, so no type of dynamic seal is required to prevent the outward leakage of the conveyed medium.

[0003] For example, a canned motor pump disclosed in the publication number CN105090051A includes a pump body, a motor housing, an impeller, and a main shaft. The motor housing is arranged on the pump body, and fixing bolts are arranged on the motor housing. The motor housing is fixedly connected to the pump body through the fixing bolts. The impeller is arranged in the pump body and fixedly connected to the main shaft. The main shaft is respectively provided with a lower bearing seat and an upper bearing seat. A shaft sleeve and a graphite bearing are respectively arranged in the lower bearing seat and the upper bearing seat. The main shaft is rotationally connected to the graphite bearing through the shaft sleeve. A end cover is arranged at the lower end of the lower bearing seat, and the end cover is hermetically connected to the pump body. A stator assembly and a rotor assembly are sequentially arranged in the motor housing. This canned motor pump is convenient to install, has a compact structure, operates stably, is easy to maintain, and adopts a circulating cooling method, so that the pump body can be kept from overheating during long-term use.

[0004] From the above disclosed solution, it can be seen that the support structure of the current canned motor pump is mostly fixedly welded to the lower end of the canned motor pump, and it is not easy to load and unload the support structure and the canned motor pump, which brings a lot of inconvenience to the loading and unloading work of the support structure and the canned motor pump. Moreover, it is not easy to fix the sealing gaskets at the inlet and outlet ends and the reflux end of the canned motor pump, so that the sealing gaskets are easily separated from the inlet and outlet ends and the reflux end, thus affecting the sealing effect of the sealing gaskets. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a combined canned motor pump that is convenient for transportation to solve the problems of loading and unloading of the support structure and the canned motor pump and sealing of the inlet and outlet ends and the reflux end.

[0006] To achieve the above object, the present utility model provides the following technical solution: a combined shielded electric pump convenient for transportation, including a pump body and a reflux end. An inlet end is fixedly arranged on the left side of the pump body, an outlet end is fixedly arranged on the upper left side of the pump body. Left retaining rings are respectively fixedly arranged on the left and right sides of the pump body, and right retaining rings are respectively fixedly arranged on the left and right sides of the pump body. Arc-shaped seats are respectively slidably clamped on the left and right sides of the pump body, and arc-shaped covers are respectively slidably clamped on the left and right sides of the pump body. A support plate is fixedly arranged at the lower end of the arc-shaped seat, and a base is fixedly arranged at the lower end of the support plate. Sleeve rings are respectively fixedly arranged on the inlet end, the outlet end and the reflux end. An annular groove is arranged inside the sleeve ring, and a gasket is slidably clamped inside the sleeve ring. A limiting ring is fixedly arranged on the outer side of the gasket. By fixedly arranging the left retaining ring and the right retaining ring, the left retaining ring and the right retaining ring respectively limit the left and right sides of the arc-shaped seat and the arc-shaped cover, avoiding the phenomenon that the pump body moves left and right after the pump body is installed, increasing the installation stability of the pump body. Thus, the pump body is limited and fixed and separated by the loading and unloading of the arc-shaped seat and the arc-shaped cover, achieving the effect of convenient loading and unloading of the pump body. At the same time, an annular groove is arranged through the sleeve ring, and the annular groove clamps the limiting ring. The limiting ring can move inside the annular groove, thereby facilitating the movement of the gasket and performing installation limitation on the gasket to avoid separation.

[0007] Preferably, a reflux pipe is fixedly arranged on the right side of the pump body, and a reflux end is fixedly arranged on the upper right side of the reflux pipe. The inlet end, the outlet end and the reflux end are respectively prior arts and will not be elaborated in this technical solution. The left retaining ring and the right retaining ring respectively limit the left and right of the arc-shaped seat and the arc-shaped cover, avoiding the pump body from moving left and right when the arc-shaped seat and the arc-shaped cover limit the pump body, and increasing the installation limitation stability of the pump body.

[0008] Preferably, the arc-shaped cover is arranged on the upper end of the arc-shaped seat. Ear plates are respectively fixedly arranged on the arc-shaped seat and the arc-shaped cover, and the ear plates are fixedly connected by bolts. Through the arrangement of the ear plates, it is convenient to fixedly connect the upper and lower ear plates by bolts, thereby achieving the effect of installing and connecting the arc-shaped seat and the arc-shaped cover. Through the arrangement of the support plate, the arc-shaped seat is supported, thereby supporting the pump body. Through the arrangement of the threaded holes, it is convenient to install and limit the base when the bolts pass through the inside of the threaded holes.

[0009] Preferably, the support plate is arranged at the lower end of the pump body, the base is arranged at the lower end of the pump body, and the base is provided with a plurality of threaded holes. By the clamping of the annular groove and the limiting ring, the installation of the gasket is limited to avoid the gasket separating from the inside of the sleeve ring.

[0010] Preferably, the material of the gasket is rubber. The gasket is tightly attached and sealed to the inlet end, the outlet end and the reflux end, and the limiting ring is slidably clamped inside the annular groove.

[0011] Compared with the prior art, the beneficial effects of the present utility model are:

[0012] (1) The utility model fixes the left retaining ring and the right retaining ring. The left retaining ring and the right retaining ring respectively limit the left and right sides of the arc-shaped seat and the arc-shaped cover, avoiding the phenomenon that the pump body moves left and right after the pump body is installed, increasing the installation stability of the pump body. Thus, the pump body is limited and fixed and disengaged by the loading and unloading of the arc-shaped seat and the arc-shaped cover, achieving the effect of convenient loading and unloading of the pump body.

[0013] (2) The utility model sets an annular groove through the collar. The annular groove is clamped with the limiting ring, and the limiting ring can move inside the annular groove, thus facilitating the movement of the gasket, installing and limiting the gasket, and preventing it from disengaging.
