Furthermore, the right end face of the inlet flange is welded with the left end face of the connecting frame, and the left end face of the outlet flange is welded with the right end face of the connecting frame.
Furthermore, one side of the first rib and one side of the second rib are welded with the inner side of the connecting frame, and the other side of the first rib and the other side of the second rib are welded with the outer side of the front bearing body.
Furthermore, the right end face of the front bearing body is welded with the excircle of the rear bearing body.
Further, a handle is arranged on the outer side of the connecting frame.
The utility model has the advantages that:
1. simplify structures such as the pump body, motor element, motor front and back lid, directly with pump body entry flange, link, the welding of pump body export flange together, with the antifriction plate of canned motor pump, bearing body and motor element shell subassembly as an organic whole, accomplish to have the leaklessly equally by the quantity that reduces standard components such as part, screw, bolt and sealed pad to the utmost. The cost is saved, the installation is easy, the structure is compact, the volume is small, the weight is light, and the carrying is convenient.
2. The utility model discloses the medium of carrying is for not having the oils of corrosivity, and nature is more stable, so adopts the design of canned motor pump, removes the housing on this basis, directly soaks stator and rotor in the medium, reduce cost, and processing is simple and convenient.
3. The rolling bearing is used for replacing a sliding bearing, so that the service life is longer, the starting performance and the bearing capacity are excellent, the price is low, the maintenance is convenient, and the operation effect is reliable. Before starting, the pump is not needed to be filled for exhausting, and the medium containing gas can be conveyed.
