Description
Technical field
The utility model relates to a kind of self-starting fuel feeding steam turbine, belongs to steam turbine field.
Background technique
Large Steam Turbine Sets after having a power failure or hypervelocity shut down, steamer due to inertia can slow reduction of speed to stopping, but self oil supply system and external oil pump quit work, now steam turbine set non lubricant oil work, serious wear between steamer and axle, artificial topping-up is slipped up unavoidably, and topping-up is not in time; External fuel cell has requirement for height, and rugged environment should not be used; Direct current oil pump cost is installed high, Maintenance Difficulty.
Model utility content
According to above deficiency of the prior art, the technical problems to be solved in the utility model is: provide a kind of and can in the time shutting down, complete the lubricated self-starting fuel feeding steam turbine of oneself.
Self-starting fuel feeding steam turbine described in the utility model, comprise large steam turbine, large steam turbine connects generator and large oil pump by rotating shaft, large oil pump oil pipe connects from opening throttle, from the high pressure oil cylinder that opens throttle and comprise sealing, high pressure oil cylinder is established spring on bottom surface, piston is established in spring upper end, piston and high pressure oil cylinder form high-voltage oil cavity, oil pipe is connected with high-voltage oil cavity, fixed valve bar on piston bottom surface, valve lever is arranged in secondary steam tube, secondary steam tube one end connects small turbine, the other end is communicated with main steam pipe, the small turbine little oil pump that is in transmission connection, little oil pump connects large steam turbine.
On secondary steam tube, quick-closing valve is also set, quick-closing valve can be blocked fast steam in the time of incoming call, and stall small turbine is given little oil pump power supply by ABAP Adapter.
Solenoid valve is set on oil pipe, little operation of oil pump when incoming call, in oil pipe, oil pressure rises, and certainly opens throttle and turn-offs, and solenoid valve is charged closes, and maintains from opening high oil pressure in throttle, keeps turn-offing from opening throttle.
Working principle and process:
In the time that large steam turbine has a power failure or exceed the speed limit shutdown, large steam turbine cannot drive large operation of oil pump, large oil pump provides lubricant oil cannot to large steam turbine, now the easy tile kilning of large steam turbine damages, charged closing under the common state of solenoid valve, in opening throttle, maintain high oil pressure, valve lever turn-offs, quick-closing valve is opened, when power failure, large steam turbine due to inertia needs a period of time could stall, now little oil pump decommissions, large steam-turbine lubrication deficient oil supply, solenoid valve power-off is opened, be back to oil pipe from opening throttle inner high voltage oil, high-voltage oil cavity oil pressure reduces, spring action valve bar moves upward, steam enters small turbine along steam tube, small turbine drives little operation of oil pump, give the not large steam turbine fuel feeding of complete stall, when incoming call, quick-closing valve turn-offs rapidly, small turbine stall, little oil pump is worked by external power source, in opening throttle, high oil pressure recovers, solenoid valve turn-offs, valve lever keeps closing, small turbine quits work, steam drives large steam turbine running.
The beneficial effect that the utility model compared with prior art had is:
Self-starting fuel feeding steam turbine described in the utility model, automatic oil supplying device power-off is opened automatically, refuels in time, prevents tile kilning, enhances productivity, and reduces fault and occurs, and without manually, automatically opens, be swift in response, wide accommodation.
