Description
Technical field
The utility model belongs to Large-scale Wind Turbines supplementary equipment optimisation technique field, particularly a kind of gearbox lubrication oil cooler.
Background technique
At double-fed, high-speed permanent magnetic and in the Large-scale Wind Turbines such as partly directly driving, gear-box is important in unit and one of requisite parts.In unit running process, gearbox high-speed operates, amount of heat can be produced, must cool it, general all employing cools gear-box indirectly to lubricant oil cooling, therefore the working condition that gear-box moistens cunning cooling system has direct impact to the working condition of whole gear-box and working life, good lubricant oil cooling can not only play enough protective actions to gear and bearing, also there is reduction friction and wear, there is high bearing capacity, prevent gummed, absorb shock and vibration, prevent fatigue equivalent, cooling, antirust, the performance such as anticorrosive.
At present, the gearbox lubrication oil cooling system generally used is: the oil sump interface of gear-box is connected with the suction inlet of oil pump by oil pipe, the import of oil delivery side of pump access wick filter, wick filter outlet is communicated with heat-operated valve import, heat-operated valve two outlet, primary outlet connects gear case oil entrance through air-cooled core body, and second outlet directly connects the oiler of gear-box by oil pipe.When temperature is greater than setting value, primary outlet opened by heat-operated valve, closes second outlet, and lubricant oil is flowed into gear case oil entrance after being lowered the temperature by air-cooled core body and carries out lubrication gear box; When temperature is less than setting value, second outlet opened by heat-operated valve, and close primary outlet, lubricant oil flows directly into gear case oil entrance and carries out lubrication gear box.The lubrication system cooling temperature dependent control valve of this gear-box, heat-operated valve is fault Multiple trauma, if lubricating oil temperature is too high, mineral oil will go bad, and lubrication, cooling effect decline, and the serious gear-box that will cause damages.
Model utility content
The purpose of this utility model is to provide a kind of gearbox lubrication oil cooler, and this device can realize two loop switch lubrications without the need to thermostat valve; And this apparatus structure is simple, long service life.
For reaching above-mentioned technical purpose, the utility model adopts following technological scheme to be achieved.
A kind of gearbox lubrication oil cooler, the oil sump interface of described gear-box is connected with the suction inlet of an oil pump, described oily delivery side of pump is connected with the import of a wick filter, it is characterized in that, described wick filter is provided with the first outlet and the second outlet, described first outlet connects the oiler of described gear-box by the first oil pipe, described second outlet connects the oiler of described gear-box by the second oil pipe, described first oil pipe is provided with one-way valve, the second oil pipe is provided with cooler.
Feature and further improvement of the technical program are:
Described cooler is wind cooling oil cooler, passes into lubricant oil in its cooling core body, and its outer installment has cooling fan.
Gearbox lubrication oil cooler of the present utility model, two loop switch lubrications can be realized without the need to thermostat valve, when lubricating oil temperature is greater than setting value, lubricant oil is lubricated gear-box after being cooled by cooler, when lubricating oil temperature is less than setting value, lubricant oil by one-way valve directly to gearbox lubrication; And this apparatus structure is simple, long service life.

Fig. 3 is the curve synoptic diagram that cooling core body inlet pressure is poor corresponding with lubricating oil viscosity coefficient;
In figure: 1, oil pump; 2, wick filter; 3, cooling fan; 4, cooling core body; 5, one-way valve; 6, gear-box; 7, the first oil pipe; 8, the second oil pipe.
Embodiment
With reference to Fig. 1, it is the linkage structure schematic diagram of a kind of gearbox lubrication oil cooler of the present utility model; The oil sump interface of gear-box 1 is connected with the suction inlet of an oil pump 1, the outlet of oil pump 1 is connected with the import of a wick filter 2, wick filter 2 is provided with the first outlet and the second outlet, first outlet connects the oiler of gear-box 6 by the first oil pipe 7, second outlet connects the oiler of gear-box 6 by the second oil pipe 8, first oil pipe 7 is provided with one-way valve 5, and the delivery outlet of one-way valve 5 connects the oiler of gear-box 6, and the second oil pipe 8 is provided with cooler.
Wherein, cooler is wind cooling oil cooler, and pass into lubricant oil in its cooling core body 4, its outer installment has cooling fan 3.
Below in conjunction with Fig. 2, Fig. 3, running principle of the present utility model is described:
Make T
1for cooling fan start-up temperature; C
1for T
1viscosity coefficient at temperature; P
e1for C
1cooling core body 4 inlet pressure under viscosity coefficient is poor, and the force value of opening of setting one-way valve 5 is P
e1.
After oil pump 1 starts, certain pressure can be formed, as lubricant oil real time temperature T<T in the inlet of one-way valve 5 and cooling core body 4
1time, according to Fig. 2, real-time lubricating oil viscosity C>C
1, more real-time cooling core body 4 inlet pressure difference P can be obtained according to Fig. 3
e>P
e1, therefore one-way valve 5 inlet pressure difference is greater than setting value P
e1, one-way valve 5 conducting, lubricant oil is directly lubricated gear-box by the first oil pipe; As lubricant oil real time temperature T>T
1time, according to Fig. 2, real-time lubricating oil viscosity C<C
1, more real-time cooling core body 4 inlet pressure difference P can be obtained according to Fig. 3
e<P
e1, therefore one-way valve 5 inlet pressure difference is less than setting value P
e1, one-way valve 5 is closed, and lubricant oil is lubricated gear-box after being cooled by wind cooling oil cooler.
Two loop switch lubrications can be realized without the need to thermostat valve according to running principle of the present utility model recited above known device, when lubricating oil temperature is greater than setting value, lubricant oil is lubricated gear-box after being cooled by cooler, when lubricating oil temperature is less than setting value, lubricant oil by one-way valve directly to gearbox lubrication; And this apparatus structure is simple, long service life.
Although be below described embodiment of the present utility model by reference to the accompanying drawings, but the utility model is not limited to above-mentioned specific embodiments and applications field, above-mentioned specific embodiments is only schematic, guiding, instead of restrictive.Those of ordinary skill in the art is under the enlightenment of specification, and when not departing from the scope that the utility model claim is protected, can also make a variety of forms, these all belong to the row of the utility model protection.
