Abstract
The utility model relates to a main bearing lubrication apparatus for horizontal helical centrifuges. A main bearing 7 is arranged on the main shaft 5 of a horizontal helical centrifuge and the side surface of the main bearing 7 is provided with an oil thrower 6. The main bearing 7 and the oil thrower 6 are installed in a bearing seat 8. The utility model is characterized in that an oil inlet is arranged on the bearing seat 8, the oil inlet is communicated with an oil inlet pipe 1, the lower part of the bearing seat 8 is communicated with an oil level stable oil tank 3 on the side of the bearing seat 8 through an oil pipe 4, and the oil level stable oil tank 3 is provided with an oil outlet which is communicated with an oil outlet pipe 2. The oil thrower can proceed with lubricating work under the conditions that oil pumps are ineffective or oil pipes are plugged, which can not make the main bearing burn out due to oil starvation. Moreover, lubricating oil can be circulated and cooled by an outer oil tank.
Description
The utility model relates to the lubricating arrangement on a kind of centrifuge.
Base bearing in the horizontal spiral discharge sedimentation centrifuge of the prior art (abbreviation horizontal screw centrifuge) has two kinds in oil foglubrication device and splash lubrication device.The oil foglubrication device is made up of oil pump, spraying oil pipe, oil return pipe, fuel tank; The pressure oil that lubricating oil is got by oil pump is lubricated base bearing by the spraying oil pipe.The base bearing of the LW-450 horizontal screw centrifuge that the north of the Changjiang River, Chongqing machinery plant produces promptly adopts oil foglubrication, in this device, lubricating oil can cool off by fuel tank, lubricating oil temperature is lower, greasy property is better, but the reliability of base bearing also will be subjected to the reliability effect of oil pump, oil pipe, and a dispensing pump lost efficacy or the oil pipe obstruction all can make base bearing burn out immediately because of oil starvation.The splash lubrication device is by the disc that is arranged on the high speed rotation on the base bearing limit lubricating oil splash to be lubricated to base bearing.The base bearing of the LW-380A type horizontal screw centrifuge of No.2 Chemical Equipment Plant, Suzhou City promptly adopts the splash lubrication device, base bearing is not easy because of oil starvation burns out like this, but lubricating oil seals in bearing block, and cooling condition is relatively poor, lubricating oil temperature is higher, the greasy property deviation.
The purpose of this utility model is to provide the horizontal screw centrifuge main bearing lubrication that a kind of greasy property is good, system reliability is high device.
Base bearing of the present utility model is contained on the horizontal screw centrifuge main shaft, and the side of base bearing is provided with disc, and described base bearing and disc are installed in the bearing block; Bearing block top has fuel feed hole, and fuel feed hole is communicated with oil inlet pipe, and the bearing block bottom is stablized fuel tank with the oil level of bearing block side and is communicated with, and oil level is stablized fuel tank and had oil-out, and this oil-out is communicated with flowline.Base bearing when work, by oil pump with lubricating fluid in oil inlet pipe is squeezed into bearing block, and make bearing block bottom and oil level stablize the certain oil level of maintenance in the fuel tank, it is fair that the height of oil level and oil level are stablized the oil-out of fuel tank; When disc rotates at a high speed, can lubricating oil splash to base bearing, produce lubrication.By oil pump lubricating oil constantly is input in the bearing block, flows out through flowline again and deliver to oil tank, just can make lubricating oil obtain better cooling effect.
The utility model compared with prior art has following advantage:
1). stablize fuel tank owing to the side at bearing block is provided with oil level, so disc is immersed in the lubricating oil all the time, disc can be proceeded lubricated work under the situation of oil pump failure or oil pipe obstruction, base bearing is burnt out because of oil starvation.
2). lubricating oil can be through the oil tank circulation and the cooling of outside, so high lubricating effect.
3). because base bearing is mainly lubricated by disc,, can saves high-pressure oil pump and carry out oil foglubrication so can the less oil pump of working pressure be sent in the bearing block by lubricating oil.
Accompanying drawing is a front view of the present utility model; Wherein,
1. oil inlet pipe; 2. flowline; 3. oil level is stablized fuel tank; 4. connection oil pipe; 5. horizontal screw centrifuge main shaft; 6. disc; 7. base bearing; 8. bearing block.
Referring to accompanying drawing; Base bearing 7 of the present utility model is contained on the horizontal screw centrifuge main shaft 5, and the side of base bearing 7 is provided with disc 6, and described base bearing 7 and disc 6 are installed in the bearing block 8; Bearing block 8 tops have fuel feed hole, fuel feed hole is communicated with oil inlet pipe 1, bearing block 8 bottoms are stablized fuel tank 3 by connection oil pipe 4 with the oil level of bearing block 8 sides and are communicated with, oil level is stablized fuel tank 3 and is had oil-out, this oil-out is communicated with flowline 2, and required oil level maintains an equal level when should work with disc 6 in the position of oil-out.During base bearing 7 work, by the oil pump effect, lubricating oil is squeezed into the bearing block 8 through oil inlet pipe 1 from being located at outside oil tank, and then stablizes fuel tank 3 through being communicated with oil pipe 4 inflow oil levels, and is flow back in the oil tank by flowline 2.Lubricating oil is at the above-mentioned heat that produces because of base bearing 7 high speed rotations in the absorption axes bearing 8 in the process that circulates, and hot lubricating oil is got back in the oil tank and cooled off, thereby has reduced lubricating oil temperature, has improved greasy property.Because oil level stablize fuel tank 3, connection oil pipe 4, bearing block 8 threes have the action principle of linker, the level height that oil level is stablized the flowline 2 on the fuel tank 3 promptly is the level height of bearing block 8, in case oil pump failure or oil inlet pipe 1 or flowline 2 stop up, oil level in the bearing block 8 still can remain unchanged, guarantee that disc 6 can rotate all the time in lubricating oil, to base bearing 7, make base bearing 7 remain lubricating condition lubricating oil splash.
