The inner side of the outer barrel is fixed with a sealing seat in an interference fit mode, the stator seat is connected with a first end portion of the sealing seat, and a second end portion of the sealing seat is connected with the guide wheel. The stator seat is connected with the sealing seat, and the motor part can be integrally fixed into the outer barrel through the interference fit of the sealing seat and the outer barrel after the motor part is assembled, so that the product structure is simplified, the installation operation and the maintenance are convenient, and the production efficiency of the product is improved.

The first end part of the sealing seat is provided with a plurality of connecting holes, and the periphery of each connecting hole is provided with a plurality of second through holes, so that the stator seat can be connected and fixed with the connecting holes through screws, and the assembly is easier.

A plurality of bolts are connected between the first end cover and the second end cover in a penetrating manner, and nuts for compressing and fixing the first end cover, the second end cover and the outer barrel are installed at the end parts of the bolts. Compared with the traditional mode that the single-side end cover is fixed by screws, the assembling structure is simplified, and the assembling efficiency is improved.

The stator seat is connected with a first wiring terminal and a second wiring terminal which extend out of the outer barrel respectively, and the outer side faces of the first wiring terminal and the second wiring terminal are in threaded connection with the outer barrel so as to facilitate installation and subsequent use and maintenance of products.

The utility model has the advantages that: in the pipeline pump, the check valve function is realized through the matching of the sealing washer and the first limber hole on the bracket, the external check valve of the traditional product can be replaced in use, the mounting structure of the product is simplified, and the use cost of the product is favorably reduced.
