Abstract
A cooling system for a speed increasing box of a wind driven generator mainly solves cooling problems of the speed increasing box, and is characterized in that an oil pump, a gear box and a wind cooler forms a closed-loop oil-circulation cooling system of the speed increasing box through pipelines, the oil pump is driven by a motor, an oil outflow port and an oil backflow port are the component parts of the closed-loop oil-circulation cooling system of the speed increasing box and arranged on the oil pump, and the oil outflow port is connected with a cooling channel of a gear box in the speed increasing box; and one end of the wind cooler is connected with the oil backflow port, and the other end of the wind cooler is connected with the cooling channel of the gear box in the speed increasing box. The cooling system of the speed increasing box of the wind driven generator can meet the cooling requirement of a large-sized wind driven generator, lubricates a gear, and simultaneously cools and reduces temperature.
Description
Technical field
The utility model relates to a kind of wind-driven generator speedup box cooling system, particularly a kind of cooling of high-power wind-driven generator speedup box.
Background technique
In wind power generating set, the slow-speed of revolution of blade wheel hub is input to generator after becoming at a high speed by speedup box, because running up of gear of speed increasing box can produce a large amount of heats, therefore must cool off.When motor size increases, the heat that distributes on the generator set per surface will increase, temperature will raise, and this makes the heating of Generator Set and cooling problem become outstanding especially, and closed circuit air speedup box cooling system can not satisfy the heat radiation requirement of 2MW wind power generating set.
The model utility content
The purpose of this utility model is to provide a kind of wind-driven generator speedup box cooling system, and this cooling system can satisfy the cooling requirement of Large-scale Wind Turbines by external pressure cooling.
The technical scheme in the invention for solving the technical problem is: this kind wind-driven generator speedup box cooling system, it is characterized in that, form a closed circuit oily circulation speedup box cooling system by oil pump, gear-box and forced air cooler by pipeline, oil pump is by motor driving, oil pump is provided with an oily outflow opening and the oily refluxing opening as above-mentioned closed circuit oily circulation speedup box cooling system constituent element, and described oily outflow opening connects the gear-box cooling channel in the speedup box; Forced air cooler one end connects oily refluxing opening, and the other end connects the gear-box cooling channel in the speedup box.
Oil circuit route is, cold oil heats up after oil pump enters the gear-box cooling channel, oil after the intensification enters forced air cooler through the cold cooling of sector-style under the effect of pump, the oil after the cooling enters booster engine gear-box cooling channel through oil pump once more, finishes a work cycle.
The beneficial effects of the utility model are: this wind-driven generator speedup box cooling system can satisfy the cooling requirement of large-scale wind driven generator, and plays the lubricated of gear in cooling.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Among the figure: 1 motor, 2 oil pumps, 3 forced air coolers, 4 gear-boxes.
Embodiment
As Fig. 1, this kind wind-driven generator speedup box cooling system, form a closed circuit oily circulation speedup box cooling system by pipeline by oil pump 2, gear-box 4 and forced air cooler 3.Oil pump 2 connects motor 1 and is driven by motor 1, oil pump is provided with an oily outflow opening and the oily refluxing opening as above-mentioned closed circuit oily circulation speedup box cooling system constituent element, described oily outflow opening connects the cooling channel of the gear-box 4 in the speedup box by pipeline, connect forced air cooler 3 through pipeline again, forced air cooler 3 connects oily refluxing opening again.Cold oil heats up enter the cooling channel of gear-box 4 through oil pump after, and the oil after the intensification flows out from gear-box under the effect of pump and enters forced air cooler through row forced air cooling cooling, and the oil after the cooling enters gear-box through oil pump once more, finishes a work cycle.
