Abstract

The invention provides a magnetic drive pump bearing box structure. The magnetic pump bearing box structure comprises a bearing box body, a first rolling bearing, an outer magnetic rotor, a second rolling bearing, a driving shaft and a driving shaft baffle. The first rolling bearing and the second rolling bearing are fixedly mounted at two ends of the bearing box body; the first rolling bearing and the second rolling bearing sleeve the driving shaft; a first horizontal oil return groove is formed in the bearing box body above the first rolling bearing, and a second horizontal oil return grooveis formed in the bearing box body below the first rolling bearing; a third horizontal oil return groove is formed in the bearing box body above the second rolling bearing, a fourth horizontal oil return groove is formed in the bearing box body below the second rolling bearing, one end of the driving shaft is sleeved with the outer magnetic rotor, an end of the outer magnetic rotor is sleeved withan inner ring of the first rolling bearing, and the outer magnetic rotor is fixedly installed on the driving shaft through a driving shaft baffle by means of a fastening screw. The bearing box structure provided by the invention can meet the requirement of stable driving of a current maximum load magnetic drive pump, an oil return structure is improved, and the oil leakage prevention capacity isgreatly improved.

Description

technical field [0001] The invention relates to a magnetic pump, in particular to a magnetic pump bearing box structure. Background technique [0002] Magnetic pumps are widely used in the transportation of dangerous liquids in petrochemical, fine chemical and other fields; their stability and ease of operation have attracted more and more attention from users; various manufacturers have entered into in-depth research on the drive configuration of magnetic pumps; With the continuous development and progress of simulation technology and new materials, the magnetic pump is gradually developing towards high power and large load. At present, the domestic magnetic pump has developed to an impeller diameter of 500mm and a power of 315kW; internationally, it has reached more than 400kW. As the power of the magnetic pump increases gradually, the stability of its bearing housing configuration becomes more and more critical. [0003] The bearing box of the existing magnetic pump has ...
