Abstract
The utility model relates to a two-stage single-suction cantilever centrifugal pump, belonging to a pump for the petrochemical industry. The utility model is composed of a front pump cover (1), a pump body (2), a pump cover (3), a threaded stud (4), nuts (5), a bearing body member (6), impeller nuts (7), a secondary impeller (8), a pump shaft (9), a primary impeller (10), and a sealing filler member (11). The bearing body of the bearing body member (6) of the pump is changed into an improved bearing body to improve the safety and the stability of the operation of the pump, and to reduce the vibration and the noise. The utility model can be widely used for delivering the petroleum, the liquefied petroleum gas, and other media without containing the solid particle for the refining of the petroleum, the petrochemical industry, the chemical industry, and other places.
Description
The utility model is to belong to petrochemical industry to use a kind of of pump.
Present Y type two-stage single suction cantilever type centrifugal oil pump all exists poor stability, generation vibration and noise are big during the pump running, pump efficiency is low, it is big to wear power of motor, can not satisfy the needs of modernization construction, user in all parts of the country appeals that manufactory will be the center with energy-conservation as soon as possible, updates to old Y type pump.
The purpose of this utility model: be to produce vibration and the bigger problem of noise when Y type two-stage single suction cantilever type centrifugal oil pump exists poor stability, pump running, and a kind of improved two-stage single suction cantilever type centrifugal oil pump is provided in order to solve.
The purpose of this utility model is achieved in that and is keeping inheriting original Y type pump structure pattern, installation dimension, under the constant situation of performance parameter, Y type pump is renovated, it mainly is the 35.50.60 bearing support of bearing body part (6) to pump, flange diameter differs greatly because dress bearing outer cylinder body profile is connected with pump cover, between rib thin and narrow, exist poor stability, generation vibration and noise are bigger during the pump running, change 45.55.70 into and improve bearing support, profile as shown in Figure 2, it is identical to improve bearing support dress bearing outer cylinder body profile and the pump cover flange diameter that links, between muscle be engaged in widening and improve pump running security and stability, reduce to vibrate and noise.
Bearing support cooling means to bearing body part (6) is improved, and has water-cooled, air cooling, fan cold, is the different serviceability temperatures according to pump, and territory of use's situation is selected for use, and what wherein fan cooled particularly was applicable to lack of water or water quality inferiority is the district.Water-cooled is to be cast with cooling chamber by bearing support inner bearing cylindrical, the heat cooling that can send bearing during by cooling chamber when the cooling water that flows or take away the purpose that reaches cooling bearing; Air cooling is that the outer surface by bearing support is cast with radiating fin, and the bearing evolution of heat is passed on the radiating fin by bearing support, is cooled off by moving air or heat is taken away the purpose that reaches cooling bearing.Fan is cold to be by the bearing support rear end fan guard (12), fan (13) to be housed, fan when pump rotates (13) rotation makes cold wind pass through fan guard (12) and blows to bearing body part (6), quicken air flows heat is taken away, reach the purpose that the cooling bearing body plays cooling bearing.Two-stage single suction cantilever type centrifugal oil pump after the improvement is by front pump cover (1), the pump housing (2), pump cover (3), stud bolt (4), nut (5), bearing body part (6), impeller nut (7), pump shaft (9), one-level impeller (10) and stuffing box packing parts (11) are formed, stud bolt (4) is contained in the pump housing (2) and pump cover (3), stuffing box packing parts (11) are contained on the pump cover (3), pump shaft (9) is contained on the bearing body part (6), to assemble pump cover (3) again is contained in pump shaft (9) and goes up and to contact with nut (5) tightly being integral with bearing body part (6), one-level impeller (10) is contained on the pump shaft (9), pack into and assemble in the pump housing (2), with pump cover (3) join the back with nut (5) tightly becoming one, sencond stage impeller (8) is contained on the interior pump shaft (9) of the pump housing (2), and with impeller nut (7) tightly, again front pump cover (1) is contained in the pump housing (2) and goes up with nut (5) tightly being integral, when rotating pump shaft (9) each string quantity evenly nothing suppress strength.
The utility model compared with prior art has following advantage:
1. the 35.50.60 bearing support with Y type pump bearing body component changes improved 45.55.70 bearing support into, improves pump running security and stability, reduces vibration and noise.
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.
The bearing cooling method of the bearing body part of this type pump (6) adopt 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.
