Table 1

Because existing cooling oil is mainly using No. 46 steam turbine oils or No. 32 steam turbine oils, No. 46 steam turbine oils are at 40 DEG C The viscous viscosity of motion is 45.8, and its preferable temperature range of operation is 44-46 DEG C；The viscous viscosity of the motion of No. 32 steam turbine oils at 40 DEG C For 32, its preferable temperature range of operation is 38-40 DEG C；Control is needed in existing cooling oil running below 65 DEG C, when cold But oil temperature is too high, and viscous viscosity diminishes, and insufficient lubrication, coefficient of friction can be caused to become big, and frictional heat aggravation, oil temperature rises rapidly Height, and oil temperature is high, aggravates the abrasion of sliding friction surface；Existing bearing adopts this cooling structure, in order to prevent oil temperature mistake Height causes mill watt, and oil temperature in bearing need to be monitored, and when temperature drift, need to increase need to increase the flow of inlet water of cooling body, When temperature is too high, reported to the police, and it is out of service.

Due to the problem that existing bearing of hydraulic generator generally existing heat exchanger effectiveness is low, easily there is report in electromotor Alert to shut down, the problem not only affects the output efficiency and economic benefit in power station, and power station shutdown and start-up course to power station its The service life of its equipment affects larger.

The reason for the problems referred to above of presence, is mainly：Because the density and viscous viscosity of cooling oil are affected by oil temperature change Larger, cooling oil temperature is higher, and density and viscous viscosity are less, and cooling oil is Jing after cooling copper tube a71 cools, and its cooling amount is larger Cooling oil sink, and flow velocity diminishes, and the less cooling oil of its cooling amount floats, and causes the lower region cooling amount of the second oil pocket a6 Larger cooling oil is detained, and the less cooling oil flow rate of the cooling amount of upper zone accelerates, and is flowed out from oil road a62, is caused The cooling oil that oil road a62 flows out is in the condition of high temperature.

In addition, bearing of the prior art, there is a problem in that：1. it supports the oiling groove design of watt inner side on top Portion, and a watt process need to be scraped to supporting watt inner side to carry out, for generating the little concave point of oil storage, improve lubrication, due in its support watt Cooling oil is to bring the little concave point of oil storage of sliding friction surface into by main shaft rotation from oiling groove, and the amount of bringing into of its cooling oil is less, Cooling oil exchange rate is low, causes to support watt bottom section exchange rate less, and because the Standard General scraped watt is often flat Square centimetre has two to three contact points, and it is scraped, and watt process is more time-consuming to take a lot of work；2. because existing outage is generally designed One end of support watt, causes the other end oil circuit of support watt obstructed, and the two ends of its support watt have the larger temperature difference, easily lead Cause to support shoe to become, and cause the phenomenon of mill watt；3. the cooling oil between the thrust bearing shoe valve and thrust disc of existing thrust bearing is directly led to Cross oil pump to be pressed into from the outside diameter of thrust bearing shoe valve, this kind of mode simple structure, but due to being hindered by centrifugal force, its cooling oil compared with Difficulty is pressed into the internal side diameter of thrust bearing shoe valve, is easily caused thrust bearing shoe valve internal side diameter high temperature tile kilning；4. Jing after manually scraping watt, scrape a watt quality and deposit In larger difference, be present larger distributional difference in the depth for scraping a watt inferior tiling, the area of its contact and oil storage point, lead It is caused to support a watt sliding friction surface to there is a problem of that oil film thickness is uneven and oil film flow velocity is uneven, sliding friction surface exists high Warm spot, easily produces impurity, causes coefficient of friction unstable；5. the big part of bearing adopts casting technique, GB casting technique 2% defect is allowed, the service life of its part is shorter, significantly impacts the stability after whole machine installation；6. bearing shell installing rack passes through Two screws in left and right are fixed, and radial vibration can be produced when hydrogenerator breaks down, and cause bearing shell to loosen, and main shaft is easy There is polarization, cause main shaft deformation；7. bearing shell watt seat is solid annular body, and thickness is big, not easy heat radiation, and volume is heavy, is being installed Shi Tongchang needs to carry out lifting the upper with loop wheel machine, and then rotation takes out another half of, and because weight is larger, taking-up is very inconvenient； 8. in existing combination bearing, comprising supporting watt and for the thrust bearing shoe valve of axially loaded for radial force, support watt and push away Power watt has been both needed to oil circuit and has passed through, and for realizing heat exchange, but because oil circuit oil resistance temperature influence is larger, oil resistance easily becomes Change, easily cause that wherein oil circuit fuel feeding is unstable, affect the stability of heat exchanger effectiveness, cause watt temperature to raise.
