Bearing cooling method to bearing body part (9), (10) improves, and has that air cooling, fan are cold, three kinds of water-cooleds, and according to the different serviceability temperatures of pump, territory of use's situation is selected for use, wherein the cold area that particularly is applicable to lack of water or water quality inferiority of fan.After the improvement this type single-stage double-suction two supports formula centrifugal oil pump is by pump cover (1), the pump housing (2), impeller (3), pump shaft (4), pump cover (5), stud bolt (6), nut (7), right stuffing box packing parts (8), right bearing body component (9), left bearing body component (10), left side stuffing box packing parts compositions such as (11), stud bolt (6) is screwed in pump cover (1) respectively, the pump housing (2), on the pump cover (5), left stuffing box packing parts (11) are contained on the pump cover (1), right stuffing box packing parts (8) are contained on the pump cover (5), impeller (3) is contained in pump shaft (4) and fixing, in the pump housing that insertion assembles (2), again with the pump cover (1) that assembles, pump cover (5) is contained in pump shaft (4) respectively and upward contacts with the pump housing (2), use nut (7) with pump cover (1) after finding gap value, pump cover (5) is fastened on the pump housing (2), left bearing body component (10) is contained in pump shaft (4) upward to contact with pump cover (1), behind the centering with nut (7) tightly being integral, right bearing body component (9) being contained in pump shaft (4) upward contacts with pump cover (5) again, behind the centering with nut (7) tightly becoming one, when rotating pump shaft (6), each string quantity evenly nothing is suppressed strength.
The utility model compared with prior art has following advantage:
1, the waterpower overcurrent position of pump cover (1), the pump housing (2), impeller (3), pump cover (5) is improved after, improve 5-8% than the efficient of the Ys type single-stage double-suction two supports formula centrifugal oil pump of same specification, reduce to wear power of motor.
2, this type pump can be widely used in petroleum refinement, petrochemical industry and chemical industry and other local oil, liquefied petroleum gas (LPG) and other media that does not contain solid particle of carrying.
3, to the cooling of the bearing of the bearing body part of this type pump have that air cooling, fan are cold, three kinds of water-cooleds, select for use according to different serviceability temperatures, territory of use's situation of pump.
