One end of the bearing gland 3 is fixedly connected with the motor wall 12 and constituted between the motor wall 12 close
Seal hydraulically full in chamber 10, the annular seal space 10；
The bearing gland 3 is provided with through hole 4 and provided with oblique through hole 11, and the through hole 4 connects the interval 5 and annular seal space
10, the oblique through hole 11 connects the hydrops region 13 and the annular seal space 10；
The oil flinger 1 is fixed on the axle 9 and positioned at bearing shell A 2 left end.
Further, in addition to axle sleeve 6, the axle sleeve 6 is arranged on the axle 9, positioned at the axle 9 and the bearing shell it
Between.
Further, the oblique through hole 11 is multiple.
Further, the bearing shell is connected with the bearing gland 3 by alignment pin 7.
In such scheme, the bearing gland 3 is connected with motor wall 12 by connecting bolt 15.
When shielding pump work, using sliding bearing cooling and lubricating device of the present invention, its two lubricating loops are same
When work, improve the lubrication and cooling condition of liquid sliding bearing in rotor-support-foundation system, can preferably reduce bearing temperature rise, subtract
Few bearing wear, enhances radial direction bearing capacity, extends the service life of bearing, and avoid high temperature from being passed further to high speed screen
Pump motor winding is covered, the operational reliability of pump assembly is improved, cost of overhaul use is reduced.
Brief description of the drawings

Embodiment
Below in conjunction with the accompanying drawings and specific embodiment the present invention is further illustrated, but protection scope of the present invention is simultaneously
Not limited to this.
A kind of sliding bearing cooling and lubricating device as shown in Figure 1, axle sleeve 6 is arranged on axle 9, bearing shell A 2, bearing shell B 8
The inwall of bearing gland 3 is fixedly connected on by alignment pin and gap coordinates on axle sleeve 6, bearing shell A 2 and bearing shell B 8 exist
It is axially arranged with interval 5, the one end of bearing gland 3 is fixedly connected with motor wall 12 by connecting bolt 15, bearing gland 3 and motor wall
It is hydraulically full in annular seal space 10, annular seal space 10 between 12, bearing gland 3 is provided with through hole 4, the connection of through hole 4 interval 5 and sealing
Chamber 10；
Oil flinger 1 is fixedly connected with axle 9, positioned at the left ends of bearing shell A 2；
The inwalls of bearing shell B 8 throw liquid bath 14 provided with spiral, and hydrops region 13, hydrops are provided between bearing gland 3 and axle 9
Region 13 is located at the right-hand members of bearing shell B 8, and bearing gland 3 is provided with least one oblique through hole 11, the oblique connection hydrops of through hole 11 region 13
With annular seal space 10.
When pump rotor rotates at a high speed, axle 9 drives oil flinger 1 to rotate together, and due to centrifugal action, liquid is in annular seal space 10
The interior oil flinger 1 that is located at can produce a low-pressure area close to the part of axle 9, and part of the oil flinger 1 away from axle 9 can produce a high pressure
Area, liquid, which leaves, enters motor seal chamber 10 after oil flinger 1, pass sequentially through through hole 4 and interval 5 flows into bearing shell A 2 and axle sleeve 6
