Abstract
The invention discloses a bearing assembly device for a centrifugal pump, which comprises a bearing seat with radiating fins, a bearing, a bearing pressing cover, an oil retaining disk and a sealing ring, wherein the bearing pressing cover is installed on the bearing seat installed on a pump shaft through the bearing. The oil retaining disk is arranged on the pump shaft, the sealing ring is arranged between the oil retaining disk and the bearing pressing cover, an impeller is arranged on the pump shaft, and an impeller shade with an air inlet and an air outlet is installed on the bearing seat. The impeller is installed on the pump shaft, and cold air is pumped in by means of high speed revolution of the impeller driven by the pump shaft, thereby on one hand, being capable of reducing the temperature of the radiating fins of the bearing seat and prolonging service life of the bearing; on the other hand, being capable of further cooling the sealing ring through a gap between the oil retaining disk and the bearing pressing cover, and prolonging service life and sealing effect of the sealing ring. The bearing assembly can not only be used for a multistage chemical centrifugal pump, but also be used for other pumps.
Description
Technical field
The present invention relates to a kind of high temperature multilevel chemical centrifugal pump that applies to industries such as oil, chemical industry, particularly relate to multilevel chemical centrifugal pump shaft bearing assembly.
Background technique
The multilevel chemical centrifugal pump is widely used in fields such as oil, chemical industry, smelting, printing and dyeing, electric power and printing and dyeing.And high temperature multilevel chemical centrifugal pump is mainly used coal liquefaction, coal for replacing oil and coal system wet goods Coal Chemical Industry industry, and the technical performance index of pump requires: design pressure≤12MPa; Operating temperature is at 250 to 300 ℃; Rotating speed≤3000rpm.Bearing as one of core component of pump is an important indicator of examination pump quality, and bearing must be being full of the use environment of lubricant oil under, in order to prevent the leakage of lubricant oil; Pump shaft is provided with oil baffle disc, between oil baffle disc and bearing gland, is provided with seal ring, because high temperature multilevel chemical centrifugal pump is after working long hours; The temperature of pump shaft is higher, and in order to reduce the temperature of parts such as bearing, bearings mounted bearing support is provided with radiating fin; Though radiating fin can reduce the temperature of pump shaft, the long-time temperature of back radiating fin of using can be increasingly high, and its radiating effect descends greatly; The seal ring that is provided with between oil baffle disc and the bearing gland is along with the rising of temperature; Ruckbildung occurs, its sealing effect descends thereupon, causes occurring the generation of oil leak phenomenon; Descended to the working life of bearing, pollute the working environment of pump on the other hand.
Summary of the invention
The object of the invention is to provide a kind of centrifugal pump of new structure to use the bearing unit device; Impeller through installing is drawn into cool air; Can reduce the temperature of bearing support radiating fin on the one hand; Come the coolant seal ring through the space between oil baffle disc and the bearing gland on the other hand, improve the working life and the sealing effect of seal ring.
The technological scheme that realizes the object of the invention is:
A kind of centrifugal pump is used the bearing unit device; Comprise flange-cooled bearing support, bearing, bearing gland, oil baffle disc and seal ring, said bearing gland be installed on the said bearing support, said bearing support through said Bearing Installation on pump shaft; Said pump shaft is provided with said oil baffle disc; Between said oil baffle disc and bearing gland, be provided with said seal ring, it is characterized in that: said pump shaft is provided with impeller, and said bearing support is provided with the impeller chimney of band air ports.
The present invention compared with prior art has following advantage:
Because impeller is installed on pump shaft, utilize pump shaft impeller high speed rotating, cool air is drawn into, can reduce the temperature of bearing support radiating fin on the one hand, the working life of improving bearing; Come further coolant seal ring through the space between oil baffle disc and the bearing gland on the other hand, improve the working life and the sealing effect of seal ring.

Embodiment
As can be seen from Figure 1, a kind of centrifugal pump is used the bearing unit device, comprises bearing support 7, bearing 8, bearing gland 5, oil baffle disc 3 and the seal ring 4 of being with radiating fin 6; Bearing gland 5 is installed on bearing support 7; Bearing support 7 is installed on the pump shaft 9 through bearing 8, and said pump shaft 9 is provided with oil baffle disc 3, between oil baffle disc 3 and bearing gland 5, is provided with seal ring 4; Pump shaft 9 is provided with impeller 2, and bearing support 7 is provided with the impeller chimney 1 of band air ports.
This bearing unit not only can be used on the multilevel chemical centrifugal pump, also can be used on the various pumps.
