Description
Technical field
The utility model relates to hydraulic turbine generator field, particularly relates to a kind of thrust-bearing of vertical hydrogenerator.
Background technique
Thrust-bearing is one of hydraulic turbine generator core component.The thrust-bearing of hydraulic turbine generator can be divided into rigid support and elastic support substantially.At present, usually rigid support is adopted in Medium and Small Hydraulic Generator group, due to position and the angle of the anti-heavy bolt of very difficult observation, measurement and accurate adjustment, when rigid support installation, maintenance, each thrust tiling is not easily transferred to same level, and each thrust bearing shoe valve uniform force often relies on the experience of installation personnel to ensure.The adjustment workload of rigid support is large, and Adjustment precision is poor, causes the dispersion degree of each thrust bearing shoe valve load during unit operation to be difficult to lower than 8%.Institute thinks guarantee safety, and the design pressure of the thrust bearing shoe valve of rigid support is generally no more than 3MPa.Due to the restriction by pressure, when unit load is larger, the tiling of thrust bearing shoe valve is long-pending must be strengthened, and the size of runner plate, thrust collar all will strengthen thereupon, and directive/guide unit weight increases, and cost improves.Due to each thrust bearing shoe valve discontinuity, during unit operation, also easily produce that watt temperature of thrust bearing shoe valve is too high, rapid wear even causes burning accident.
Model utility content
For the deficiency that above-mentioned prior art exists, the utility model provides a kind of can regulate flexible self balancing supporting mechanism stressed between balanced each piece of thrust bearing shoe valve automatically.
Technical solution adopted in the utility model is: a kind of flexible self balancing supporting mechanism, comprises several flexible units, several connecting tubes, one-way valve, plug, chassis, holder, and described chassis is toroidal, the inside of several flexible units described is equipped with cavity, several flexible units are fixed on the upper surface on chassis, and several flexible units are arranged along the circumference uniform distribution on chassis, often be communicated with a connecting tube between adjacent two flexible units, the sidewall of one of them flexible unit of several flexible units described offers oil hole and bleeder hole, described oil hole is by plug shutoff, described bleeder hole is by the shutoff of peace one-way valve, cavity is provided with in the middle part of described holder, it is outside that holder is sleeved on several flexible units, holder is fixed on chassis, the top of several flexible units is placed in the outside of holder.
The beneficial effects of the utility model are:
1. several flexible units of the present utility model be communicated with several connecting tubes and become as a whole after, the turbine oil with certain initial pressure is full of after adopting inner vacuumizing, and make flexible unit produce elastic strain, the air avoiding flexible unit inner remaining with connecting tube is different with the compressive deformation of turbine oil, affects the self balancing effect of flexible self balancing.
2. holder of the present utility model is sleeved on several flexible units outsides, and holder is fixed on chassis, plays a good protection to parts such as several flexible units and several connecting tubes.

Embodiment
As shown in Figure 1 to 4, a kind of flexible self balancing supporting mechanism, comprises several flexible units 1, several connecting tubes 2, one-way valve 3, plug 4, chassis 5, holder 6, and described chassis 5 is toroidal, the inside of several flexible units 1 described is equipped with cavity, several flexible units 1 are fixed on the upper surface on chassis 5 respectively by fastening screw trip bolt 7, and several flexible units 1 are arranged along the circumference uniform distribution on chassis 5, often be communicated with a connecting tube 2 between adjacent two flexible units 1, the sidewall of one of them flexible unit 1 of several flexible units 1 described offers oil hole and bleeder hole, described oil hole is by plug 4 shutoff, described bleeder hole is by the shutoff of peace one-way valve 3, cavity is provided with in the middle part of described holder 6, it is outside that holder 6 is sleeved on several flexible units 1, holder 6 screw assemblies 8 is fixed on chassis 5, the top end that the top of several flexible units 1 is placed in the outside holder 6 of holder 6 is provided with unit thrust bearing shoe valve limiting stopper.
Described each flexible unit 1 comprises a casing 1-1 and iron block 1-2, the middle part of described casing 1-1 outer side wall is provided with curl projection, the sidewall of described casing 1-1 offers two connecting tube through holes, the two ends of described connecting tube 2 are connected with one of them the connecting tube through hole on adjacent two casing 1-1 sidewalls, described iron block 1-2 is arranged in the cavity of casing 1-1, and the upper plane of iron block 1-2 and the upper plane of casing 1-1 are in same level and be tightly connected with electric welding.
The sidewall of described holder 6 offers lifting eye.
Working principle: according to unit thrust loading needs on annular chassis 5, installs several flexible units 1, often adopt connecting tube 2 to be communicated with between adjacent two flexible units 1, and integral installation is on chassis 5.After installation, the overall machining of lower plane on the upper plane of all flexible units 1 and chassis 5 is smooth, utilizes machining to ensure planeness and the parallelism of the lower planes of flexible self balancing supporting mechanism of the present utility model.Utilize the bleeder hole on one of them flexible unit 1 sidewall all flexible units 1 and connecting tube 2 inside to be evacuated, be then full of turbine oil, form connecting vessels, make each flexible unit 1 become one and wait compressed-oil system.Holder 6 is arranged on chassis 5, in order to protect flexible unit 1 and connecting tube 2, utilizes the lifting eye of holder 6 sidewall can lift by crane whole mechanism.The upper plane of holder 6 is as the measuring basis of flexible unit 1 amount of deformation.The middle part of the casing 1-1 outer side wall of flexible unit 1 is that curl is protruding, curl projection makes casing 1-1 have elasticity, the turbine oil that inside is filled with has certain initial pressure, it is made to produce resiliently deformable, during work under the effect of outside axial force, there is axial elasticity distortion in flexible unit 1, gets back to height during free state, utilize and bear outside thrust load to the compression of its inside turbine oil and the plastic deformation of flexible unit 1 outer wall.By law of connected vessels, the unequal external load that each flexible unit 1 bears passes to other flexible units 1 automatically by the turbine oil be communicated with, make the load on each flexible unit 1 automatically obtain equilibrium, thrust loading when finally making unit operation, each piece of thrust bearing shoe valve born is balanced.Use the utility model, the height of each piece of thrust bearing shoe valve and stressed need not be adjusted when units' installation, maintenance, substantially increase installation precision and efficiency, decrease the workload of installation, maintenance, avoid due to each piece of thrust bearing shoe valve discontinuity, cause indivedual Thrust Tile Abrasion aggravate or cause thrust bearing shoe valve burning accident, unit can not be run.Because flexible self balancing supporting mechanism has the stressed feature of autobalance, the pressure of thrust bearing shoe valve can improve 1.5 times, in identical thrust loading situation, the size of unit thrust bearing shoe valve can reduce, the size of runner plate, thrust collar also can reduce, the more compact structure of hydraulic generator thrust bearing, rationally, overall economic efficiency is remarkable.
