The specific embodiment
Accompanying drawing discloses the structural representation of the related preferred embodiment of the utility model without limitation; Below with reference to accompanying drawing, explain the technical solution of the utility model.
As illustrated in fig. 1 and 2, support roller 26 is arranged in rotating shaft 24, and rotating shaft 24 is rotated together with support roller 26.Rotating shaft 24 is pressed on lining tile 25, and lining tile 25 is fixed on cooling watt 23, then is fixed on bearing base 6, and bearing base 6 is fixed on base 27.Lining tile 25 does not rotate, and rotating shaft 24 and lining tile 25 relative slidings form sliding bearing.On base 27, be provided with tank.
Cooling watt of 23 internal productions have pipeline, and a side leaves into water interface, and a side leaves water outlet mouthpiece, make cooling water in cooling watt 23, carry out exchange heat, take away from lining tile 25 and transmit the amount of heat of coming.
Vibration means for main pipe for supplying water 8 is received factory's recirculated water feed pipe, so that cooling water to be provided.Backwater supervisor 14 receives factory's recirculated water return pipe, so that cooling water is got back to factory's pump station of recirculation water, and recycling.Drain header 20 is received drainage pipeline outside factory.
Pressure of supply water table 11 is installed on vibration means for main pipe for supplying water 8, on backwater supervisor 14, pressure of return water table 19 is installed, the pressure of supply water of vibration means for main pipe for supplying water 8 is greater than backwater supervisor 14 pressure of return water, and circulating water pressure is poor to be subtracted each other and obtained by pressure of supply water table 11 and pressure of return water table 19.Pressure in drain header 20 can be considered as 0, and outer discharge pressure is poor is the registration of pressure of supply water table 11.
Vibration means for main pipe for supplying water 8 is connected with cooling watt 23 water inlet interface through water supply arm 9, so that cooling water to be provided.On water supply arm 9, be provided with water supply valve 10.Cooling watt of 23 water outlet mouthpieces are connected with backwater supervisor 14 through return branch 12, so that cooling water enters recirculated water water return pipeline.In return branch 12, be provided with backwater valve 16.
In the return branch between cooling watt 23 and backwater valve 16, be connected with the first branch drain 13 and the second branch drain 15.The first branch drain 13 is connected to the tank top that drain header 20, the second branch drain 15 delivery ports are arranged on base 27.On the first branch drain 13, be provided with on first row penstock 17, the second branch drains 15 and be provided with second row penstock 18.
The tank of base 27 is connected with pipeline 22, and pipeline 22 is connected with water-level regulator 21, and water-level regulator 21 is connected with drain header 20.
Described heat insulation cover plate comprises ring side heat shield 1 and end face heat shield 2, and they are comprised of double-deck sheet metal, and centre fills up heat-barrier material.Ring side heat shield 1 is arranged on bearing upper cover 5 by the first support 3 and the second support 4.Operation principle:
Cooling segment:
The cooling water of supplying with from recirculated water feed pipe, distributes to through vibration means for main pipe for supplying water 8 arm 9 that respectively supplies water, and through water supply arm 9, enters cooling watt 23, at cooling watt 23, interiorly flows one week fully to complete heat exchange, and the heat passing over from lining tile 25 is taken away in time.Cooling water from cooling watt 23 out after, have three paths.Article one, path is directly via return branch 12, to import backwater supervisor 14, and by cooling water drainage, in recirculated water return pipe, formation recycles; Second path is that cooling water directly drains into drain header 20 through the first branch drain 13 by cooling water, then the direct outer outer drainage pipeline that drains into; A Third Way footpath is that cooling water drains in the tank of base 27 through the second branch drain 15, through pipeline 22, drains into water-level regulator 21, finally by the outer drainage pipeline that drains into of drain header 20.
When normal work, first row penstock 17 is closed, and second row penstock 18 is crack, only need supply with minute quantity cooling water to the tank of base 27, then regulates retainings height via water-level regulator 21, reaches the temperature that reduces near equipment such as base 27 grades.Regulate water supply valve 10 and backwater valve 16, and regulate cooling water inflow in conjunction with the temperature of the pressure reduction between pressure of supply water table 11 and pressure of return water table 19 and lining tile 25, temperature stabilization is being required below temperature.
When fluctuation appears in status of equipment, lining tile 25 caloric values increase, when temperature raises, increase the aperture of water supply valve 10 and backwater valve 16 to increase cooling water flow, observe lining tile 25 temperature and whether be stabilized in and require below temperature, if temperature temperature keeps valve opening, after temperature declines, progressively reduce the aperture of water supply valve 10 and backwater valve 16.If temperature can not be stablized, need more substantial cooling water, open first row penstock 17, the cooling water of closing completely in the anti-non-return water supervisor 14 of backwater valve 16 pours in down a chimney to branch drain, regulate water supply valve 10 and first row penstock 17 to regulate cooling water flow, temperature stabilization is being required below temperature.After temperature declines, close first row penstock 17 completely, open back-water valve (BWV) 16, the control method while entering normal work.
When needs reduce support roller temperature, regulate water-level regulator 21, change retaining height, make the height of water level in tank reach requirement.
When shutting down maintenance, need to stop cooling water or water supply valve 10 is closed completely, when start, reopen.
Guard section:
Radiation of equipment heat, in radiative process, if be directly radiated on bearing upper cover 5 and bearing (ball) cover 7, will made the temperature of bearing upper cover 5 and bearing (ball) cover 7 rise, thereby communicate the temperature on axle 24 and lining tile 25, and this is unfavorable for the cooling of bearing.
The ring side heat shield 1 arranging can block the radiations heat energy at bearing top and rear, and end face heat shield 2 blocks axle head heat, and two heat shields keep off a large amount of radiations heat energies outside heat shield, reduce the temperature of bearing upper cover 5 and bearing (ball) cover 7.
