Description
Technical field
The utility model relates to a kind of sink, particularly relates to a kind of novel wind generator gear-box sink.
Background technique
In wind power generating set, gear-box is an important mechanical part, its major function is that the transmission of power that produced under wind-force effect by wind wheel makes it reach corresponding rotating speed to generator, the rotating speed of wind wheel is low, and the accelerating function having to pass through gear-box gear pair can reach the demand rotating speed of generator.
At present, the lubrication of gear case of blower adopts forced lubricating system more, lubrication system is generally made up of gear pump, thermostat valve, filter, cooler, oil pipe line, supervisory device and control system, the lubrication system of existing typical gearbox of wind turbine, during work, when gear-box oil temperature reaches 55 DEG C, thermostat valve cuts out, wind cooling oil cooler starts automatic operation, lubricant oil enters gear-box again after supercooler cooling, when oil sump temperature drops to 45 DEG C, cooler quits work automatically, and lubricant oil directly enters gear-box through thermostat valve and carries out pressure lubrication.In order to protect gear-box, when gear-box oil sump temperature is greater than 75 DEG C or bearing temperature is greater than 90 DEG C, wind-driven generator reduces Power operation automatically, namely limits power; When oil sump temperature is greater than 80 DEG C or bearing temperature is greater than 95 DEG C, wind-power electricity generation chance autostop, resets after temperature reduces again.
The Wind turbines newly dispatched from the factory, the mechanical efficiency of its gear-box is generally not less than 97%, when blower fan Operation at full power, because of the friction such as gear, bearing and the stirring etc. to lubricant oil, the heat energy being about its rated power 3% can be produced, due to long-term running, the wearing and tearing of gear, bearing, the efficiency of gear-box can decline, and its heat produced can increase to some extent.When flow one timing of lubrication system oil pump; the cooling power of forced air cooler has relation with ambient temperature and ventilation; ambient temperature is lower, and ventilation is larger, and cooling power is higher; when running into high temperature strong wind weather; or cooler adhering dust, batting ventilation decline time, just there will be heat radiation power deficiency, cause Wind turbines limit power or shut down phenomenon occur; thus affect generated energy, cause economic loss.
China's wind-powered electricity generation installation quantity constantly increases in recent years, and the problem of gear-box excess temperature constantly appears in some areas, and slowly could not be solved.
Summary of the invention
For solving the problems of the technologies described above, the utility model proposes a kind of novel wind generator gear-box sink, comprise support, described support installing is in the side of the fixing frame of original gear case cooler;
Described support is provided with newly-increased wind cooling oil cooler;
Described newly-increased wind cooling oil cooler, by the base set gradually from bottom to up, is arranged on the fan on base, is arranged on the exhaust outlet at fan top, with between exhaust outlet by the exhaust port that soft cloth air channel is connected, be arranged at rain cover above exhaust port and form;
Described base side is provided with oil circuit, the crude oil road serial or parallel connection bottom described oil circuit and original gear case cooler.
During work, fan rotates, and wind is sent from exhaust outlet, discharges behind soft cloth air channel through exhaust port, reduces bottom oil circuit temperature, plays radiating effect.
A kind of novel wind generator gear-box sink described in this patent, increased a newly-increased wind cooling oil cooler newly on one side at original gear case cooler, cooling effect is better; Be provided with rain cover on newly-increased wind cooling oil cooler top, can effectively prevent rainwater from pouring in down a chimney.
This patent overall structure is simple and reliable, designs ingenious, and can carry out improving on existing equipment basis, manufacture cost be not high, is conducive to large-scale promotion and uses.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
See Fig. 1, a kind of novel wind generator gear-box sink, comprises support 6, and described support 6 is arranged on the side of the fixing frame 11 of original gear case cooler 7;
Described support 6 is provided with newly-increased wind cooling oil cooler 10;
Described newly-increased wind cooling oil cooler 10 is by the base 1 set gradually from bottom to up, be arranged on the fan 2 on base 1, be arranged on the exhaust outlet 8 at fan top, with the exhaust port 3 be connected by soft cloth air channel 9 between exhaust outlet 8, the rain cover 4 be arranged at above exhaust port 3 is formed;
Described base 1 side is provided with oil circuit 5, crude oil road 12 serial or parallel connection bottom described oil circuit 5 and original gear case cooler 7.
Embodiment recited above is described preferred implementation of the present utility model; not scope of the present utility model is limited; do not departing under the utility model designs spiritual prerequisite; the various distortion that the common engineers and technicians in related domain make technical solutions of the utility model and improvement, all should fall in protection domain that claims of the present utility model determine.
