Below in conjunction with accompanying drawing, the invention will be further described.
As shown in Figure 1, a kind of tube centrifuge is without the lower bearing equipment of grease contamination, comprise step 2, bearing holder (housing, cover) 3 and bearing 4, bearing holder (housing, cover) 3 is fixed in step 2, bearing 4 is arranged in bearing holder (housing, cover) 3, described lower bearing equipment also comprises container 12, and step 2 is provided with liquid inlet 15, liquid outlet 11 and correspondingly path 10, and liquid inlet 15 is connected with container 12 by woven hose 13.
In actual applications, lower bearing equipment is fixed on the support 1 of centrifuge fuselage, conveniently lower bearing equipment is dismantled, cleans, is changed the accessory saving operating time in maintenance, strengthen operating efficiency, lower bearing equipment also comprises bearing cap 8, stage clip 5, locking nut 6 and gland 7, bearing cap 8 is arranged on the surface of bearing holder (housing, cover) 3, stage clip 5 is fixed between gland 7 and bearing holder (housing, cover) 3, locking nut 6 is connected with step 2 by screw thread respectively with gland 7, the replacing of such spare and accessory parts, clean very convenient; Pressure when running to woven hose 13 or centrifuge to prevent the liquid backflow in step 2 in step 2 reduces the fluid pressure of liquid inlet 15, the path 10 at liquid inlet 15 place is provided with block 9, the size and shape of block 9 is determined according to the actual conditions of path 10, in manufacturing process, block 9 and step 2 carry out overall processing.
In actual applications, liquid selects water or other free of contamination liquid, when lower bearing equipment runs up, in order to farthest reduce the friction of bearing 4, the horizontal plane at the discharge outlet place of liquid outlet 11 is not less than the end face of bearing 4, that is all must be immersed in water or free of contamination liquid when bearing 4 operates, the phenomenon of lack of water or free of contamination liquid can not have been had; Material enters in the drum device of centrifuge by sparge pipe 14, woven hose 13 is connected with the bottom of container 12, woven hose 13 is or/and liquid outlet 11 is provided with valve, in order to realize the Automated condtrol of centrifuge, lower bearing equipment is provided with controller, and woven hose 13 is or/and the valve of liquid outlet 11 selects magnetic valve, and magnetic valve is connected with controller by holding wire, the unlatching of magnetic valve is operated by controller completely, and people only need input instruction on the controller.
In addition, in order to farthest save cost, liquid selects water, the both sides of the bottom of step 2 are provided with liquid inlet 15 and liquid outlet 11, as long as the liquid level of water is higher than the certain height of the plane of liquid outlet 11 in container 12, when opening the valve on woven hose 13, because the liquid level of water in container 12 is higher than the certain height of the horizontal plane at the discharge outlet place of liquid outlet 11, the inside that water enters step 2 by woven hose 13 from liquid inlet 15 is lubricated, namely lubricate between bearing holder (housing, cover) 3 and step 2, reduce the frictional dissipation of centrifuge bearing 4 when running up, last water is discharged from the discharge outlet of liquid outlet 11.
The invention also discloses the lubricating method of a kind of tube centrifuge without the lower bearing equipment of grease contamination, comprise the steps:
The in-built full water of container 12 or free of contamination liquid;
The inside that water or free of contamination liquid enter step 2 by woven hose 13 is lubricated, step 2 is provided with liquid inlet 15, liquid outlet 11 and correspondingly path 10, liquid inlet 15 is connected with container 12 by woven hose 13, and in container 12, the liquid level of water or free of contamination liquid is higher than the certain height of the horizontal plane at the discharge outlet place of liquid outlet 11;
Discharge from liquid outlet 11 after water or free of contamination hydrodynamic lubrication.
In actual applications, when lower bearing equipment runs up, in order to farthest reduce the friction of bearing 4, the horizontal plane at the discharge outlet place of liquid outlet 11 is not less than the end face of bearing 4, that is all must be immersed in water or free of contamination liquid when bearing 4 operates, the phenomenon of lack of water or free of contamination liquid can not have been had; In order to the fluid pressure preventing the pressure be back to when woven hose 13 or centrifuge run in step 2 of the water in step 2 from reducing liquid inlet 15, the path 10 at liquid inlet 15 place is provided with block 9, the size and shape of block 9 is determined according to the actual conditions of path 10, in manufacturing process, block 9 and step 2 carry out overall processing.
In actual applications, woven hose 13 is connected with the bottom of container 12, woven hose 13 is or/and liquid outlet 11 is provided with valve, in order to play lubricant effect better, improve the pressure of water or free of contamination liquid, accelerate the flow velocity of water or free of contamination liquid, namely by the liquid level of water or free of contamination liquid in container 12 higher than a lot of height of the horizontal plane at the discharge outlet place of liquid outlet 11, such as between the two the discrepancy in elevation at 5 more than ㎝.
Operation principle of the present invention: when after the in-built full water of container 12 or free of contamination liquid, open the valve on woven hose 13, due to the pressure reduction of liquid, the inside that water or free of contamination liquid enter step 2 by woven hose 13 from liquid inlet 15 is lubricated, namely lubricate between bearing holder (housing, cover) 3 and step 2, reduce the frictional dissipation of centrifuge bearing 4 when running up, in order to farthest reduce the friction of bearing 4, the horizontal plane at the discharge outlet place of liquid outlet 11 is not less than the end face of bearing 4, after centrifuge shuts down, the valve opened on liquid outlet 11 is discharged water or free of contamination liquid from the discharge outlet of liquid outlet 11, in order to play lubricant effect better, improve the pressure of water or free of contamination liquid, accelerate the flow velocity of water or free of contamination liquid, namely by the liquid level of water or free of contamination liquid in container 12 higher than a lot of height of the horizontal plane at the discharge outlet place of liquid outlet 11, such as between the two the discrepancy in elevation at 5 more than ㎝.Because the present invention adopts water or free of contamination liquid to lubricate, therefore tube centrifuge is without the maintenance of the lower bearing equipment of grease contamination and disassembling section is convenient, structure is simple, stop grease causes second time grease to be atomized to product to pollute, reach desirable quality product, break through the insurmountable difficult problem of the industry.
The above; be only the specific embodiment of the present invention, but protection scope of the present invention is not limited thereto, the technical staff of any skilled is in technical scope disclosed by the invention; the change that can expect easily or replacement, all should be encompassed within protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection domain of described claim.
