Description
Technical field
The utility model belongs to electrical generator fields, is specifically related to a kind of generator lubrication system.
Background technique
The lubricating system that existing dynamo bearing adopts is oil ring selflubricating mostly, this kind of lubricating system relies on generator axle journal to the frictional force of the oil ring be enclosed within axle, drive oil ring rotates, utilize lubricant oil from the oil sump of bearing chamber bottom, to take oil to journal surface to the adhesive force of oil ring, the frictional heat energy dependence bearing chamber body shell that its motion produces externally air diffuses cooling.This kind of lubricating system is because being limited to its lubrication and thermal equilibrium mode, it is larger by the impact of temperature inevitably to there is lubrication effect in it, this is because how many impacts that oil body hangs oil mass to oil ring are very large, and oil body is by the impact of ambient operating temperature, when the temperature is too low, lubricating oil viscosity increases, the viscous force of oil ring is also increased, thus partly or entirely counteract the frictional force that pivot journal drives oil ring rotation, oil ring rotate stagnate or rotating speed relative excessively slow, thus after causing generator rotation, within a period of time between axle and bearing shell because lubricants capacity cannot form the effect of hydrodynamic lubrication not, and when ambient operating temperature is too high, bearing housing heat dissipation potential is limited, moving the heat produced will in bearing chamber inner accumulated, running time is longer, heat accumulation is higher, lubricating oil temperature is also higher, thus lubricating oil viscosity is reduced, oil ring band oil mass diminishes, the dynamic pressure oil film formed between axle and bearing shell is thinning, part contact surface produces direct contact friction, thus a large amount of frictional heat that produces makes bearing temperature sharply raise further, produce vicious circle, Bearing Temperature unit finally may be caused to be lowered the temperature by forced-stopping machine.
Summary of the invention
For the deficiencies in the prior art, the purpose of this utility model is to provide a kind of generator lubrication system, and abundant, the oily loss of fuel feeding is little, good heat dissipation effect.
Generator lubrication system described in the utility model, comprise electric generator casing, casing internal is provided with transmission shaft, the two ends of transmission shaft are respectively equipped with fore bearing and rear bearing, fore bearing, rear bearing lays respectively at front-end bearing pedestal and rear bearing block is inner, front-end bearing pedestal top is provided with fore bearing filler opening, rear bearing block top is provided with rear bearing filler opening, front-end bearing pedestal one sidewall is provided with fore bearing oil outlet, rear bearing block one sidewall is provided with rear bearing oil outlet, steam turbine oil tank outlet connects oil pump successively by pipeline, reduction valve and oil cooler, oil cooler connects fore bearing filler opening and rear bearing filler opening successively by pipeline, steam turbine oil tank import connects fore bearing oil outlet and rear bearing oil outlet respectively by pipeline.
During use, lubricant oil under the effect of oil pump from steam turbine oil tank out, reduce pressure through reduction valve, lower the temperature through oil cooler, then, lubricating bearings fore bearing and rear bearing is entered from fore bearing filler opening and rear bearing filler opening, front-end bearing pedestal one sidewall is provided with fore bearing oil outlet, rear bearing block one sidewall is provided with rear bearing oil outlet, when lubricant oil in current axis bearing or rear bearing block exceedes fore bearing oil outlet or rear bearing oil outlet, lubricant oil is discharged from fore bearing oil outlet or rear bearing oil outlet, the position of front-end bearing pedestal and rear bearing block is higher than steam turbine oil tank position, lubricant oil is back in steam turbine oil tank under gravity, lubrication oil circulation uses, loss is few, and prevent the lubricating oil temperature in bearing too high.By arranging fore bearing oil outlet or the height of rear bearing oil outlet on front-end bearing pedestal or rear bearing block, the amount of lubricant oil in adjustment bearing.
In sum, the utility model has the following advantages:
(1) the utility model is rational in infrastructure, achieves lubrication oil circulation and uses, make lubrication oil consumption few, and lubrication oil circulation uses and the lubricating oil temperature in bearing can be prevented too high.
(2) generator lubrication system described in the utility model can be applicable to large-scale, heavy, at a high speed, in the various machinery of accurate and automation.
