Zusammenfassung:The utility model discloses a novel horizontal multistage centrifugal pump with rolling bearings. The novel horizontal multistage centrifugal pump is characterized by comprising a bearing component of a driving portion, a sealing tank of the driving portion, a suction section, a pump body, a discharge section, a sealing tank of a non-driving portion, a bearing component of the non-driving portion and a pump shaft, the bearing component of the driving portion, the sealing tank of the driving portion, the suction section, the pump body, the discharge section, the sealing tank of the non-driving portion, the bearing component of the non-driving portion and the pump shaft are sequentially connected with one another, and the bearing component of the non-driving portion comprises a bearing housing cover, a single-row cylindrical rolling bearing, an oil slinger sleeve I, an angular contact ball bearing set, a bearing gland, a locking nut, a bearing non-rotating sleeve, an oil slinger I, a bearing housing, an oil slinger sleeve II and an oil slinger II. The single-row cylindrical rolling bearing and the angular contact ball bearing set are respectively individually lubricated, and the bearing non-rotating sleeve is not radially positioned. The novel horizontal multistage centrifugal pump has the advantages that the novel horizontal multistage centrifugal pump can be easily and conveniently mounted and detached; good lubricating effects can be realized, and the novel horizontal multistage centrifugal pump is safe and reliable and can bear high residual axial force; the rolling bearings are low in cost as compared with bearing pads, and accordingly the cost can be saved.
