For better understanding of the present invention, the lubrication system, the lubrication method and the wind turbine generator set according to the embodiments of the present invention are described in detail below with reference to fig. 1 to 5.
Fig. 1 shows a partial structural schematic diagram of a wind turbine generator system according to an embodiment of the present invention, and fig. 2 shows a structural schematic diagram of a lubrication system according to an embodiment of the present invention. Referring to fig. 1 and fig. 2 together, an embodiment of the invention provides a wind turbine generator system, which includes a tower 200, a nacelle base 300, and a yaw bearing 400 connecting the nacelle base 300 and the tower 200, where the yaw bearing 400 includes a bearing raceway 401 and a gear ring 402, and the rotation of the nacelle base 300 relative to the tower 200 can be realized through the yaw bearing 400, so as to meet the yaw requirement of the wind turbine generator system, and further ensure the power generation benefit of the wind turbine generator system.
In the service process of the yaw bearing 400, in order to ensure long-term stable operation and guarantee the service life of the yaw bearing, the bearing raceway 401 and the gear ring 402 of the yaw bearing 400 need to be lubricated according to requirements, and therefore, the wind generating set of the embodiment of the invention further comprises the lubricating system 100, and the lubricating requirements on the bearing raceway 401 and the gear ring 402 can be better met through the lubricating system 100.
As shown in fig. 2, an embodiment of the present invention provides a lubrication system 100 for lubricating a bearing raceway 401 and a gear ring 402 of a yaw bearing 400, where the lubrication system 100 includes a grease supply device 10, a lubrication pipeline 20, and a valve assembly. The grease supply device 10 can supply grease, the lubrication line 20 includes a first branch 22 and a second branch 23 connected to the grease supply device 10 and used for obtaining the grease, the first branch 22 includes a first guide pipe 221 and a lubrication portion 222 connected to the first guide pipe 221, and the lubrication portion 222 can be matched with the gear ring 402 and used for conveying the grease obtained by the first branch 22 to the gear ring 402. The second branch 23 includes a second guide pipe 231 and a grease injector 232 connected to the second guide pipe 231, the grease injector 232 being capable of connecting to the bearing race 401 and delivering grease captured by the second branch 23 to the bearing race 401. A valve assembly is provided in the lubrication line 20 to control the opening and closing of the first branch 22.
The lubricating system 100 provided by the embodiment of the invention can meet the lubricating requirements on the bearing raceway 401 and the gear ring 402 of the yaw bearing 400, and the gear ring 402 is uniformly lubricated, so that the yaw bearing 400 can stably run, and the power generation benefit of the wind generating set is further ensured.
Specifically, the grease supply device 10 according to the embodiment of the present invention may include an accommodating box 11 and a driver 12, the grease supply device 10 contains grease through the accommodating box 11, and the driver 12 is connected to the accommodating box 11 and the lubrication pipeline 20 to deliver the grease to the lubrication pipeline 20.
In some alternative examples, the actuator 12 may include a driving pump 122 and a driving motor 121 connected to each other, the driving pump 122 is connected to the accommodating box 11 and the lubrication line 20, and the driving pump 122 is operated by powering the driving motor 121 to deliver the grease in the accommodating box 11 to the lubrication line 20.
In order to supply the first branch 22 and the second branch 23 of the lubrication pipeline 20 with liquid through the driving pump 122, as an optional embodiment, the lubrication pipeline 20 further includes a main pipeline 21 connected to the first branch 22 and the second branch 23, the lubrication pipeline 20 is connected to the grease supply device 10 through the main pipeline 21, and the main pipeline 21 is specifically connected to an outlet of the driving pump 122 to obtain grease from the grease supply device 10.
The first guide pipe 221 of the first branch 22 and the second guide pipe 231 of the second branch 23 may be circular pipes, square pipes or other pipes according to the use requirement, and the pipe diameters may be set according to the use requirement, which is not specifically limited herein.
The lubrication portion 222 of the first branch 22 may specifically adopt a gear, and the grease obtained by the first branch 22 is conveyed to the lubrication portion 222 through the first guide pipe 221. Because the lubricating portion 222 is of a gear structure, it can be engaged with the gear ring 402 to be lubricated by the yaw bearing 400, so as to lubricate the gear ring 402, and the lubricating effect on the gear ring 402 can be better ensured. Of course, the lubrication portion 222 may be a gear structure, but is not limited thereto, as long as the lubrication requirement for the gear ring 402 can be met, and for example, the lubrication portion may also be a flexible structure such as a brush.
The grease injector 232 of the second branch 23 may be selected according to the lubrication requirement, for example, a QSL7 type grease injector of LINCOLN may be adopted, and certainly, grease injectors 232 of other types or different manufacturers may be adopted as long as the lubrication requirement of the bearing race 401 can be met.
As an alternative embodiment, the valve assembly may include a first control valve 31 disposed in the lubrication line 20, and the valve assembly controls the on/off of the first branch 22 through the first control valve 31, as shown in fig. 2, the first control valve 31 of the valve assembly may be specifically disposed in the first branch 22 of the lubrication line 20 and is a normally closed two-position two-way valve. When the general control of the wind generating set sends out an instruction to lubricate the bearing raceway 401 of the yaw bearing 400, the driving motor 121 of the driver 12 may be powered on, and the lubricating grease may be delivered to the lubricating pipeline 20 through the driving pump 122. Because the first control valve 31 is a normally closed two-position two-way valve, when the first control valve 31 is not powered on, the grease entering the lubrication pipeline 20 cannot be delivered to the lubrication portion 222 of the first branch 22, and can only be delivered into the grease injector 232 from the second guide pipe 231 of the second branch 23, and then enters the bearing race 401 through the grease injector 232 to lubricate the bearing race 401.
During the process of lubricating the bearing race 401, in order to allow the grease in the grease injector 232 to completely enter the bearing race 401 and lubricate it, the line of the lubrication line 20 between the grease injector 232 and the grease supply device 10 may be vented. Therefore, as an alternative embodiment, a pressure relief branch 24 having a pressure relief valve 241 is connected between the housing box 11 of the grease supply device 10 and the lubrication line 20 to relieve the lubrication line 20.
In order to better satisfy the pressure release requirement on the lubrication pipeline 20, optionally, the lubrication system 100 further includes a pressure detector 26 and a controller, the pressure detector 26 is disposed in the lubrication pipeline 20 and detects the pressure of the lubrication pipeline 20, the controller is connected to the driver 12 and the pressure release valve 241, when the pressure detector 26 detects that the pressure in the lubrication pipeline 20 reaches a preset pressure value, the pressure detector 26 sends a pressure release signal, the controller controls the pressure release valve 241 to open according to the pressure release signal, and controls the driver 12 to close, so as to complete the pressure release of the lubrication pipeline 20, thereby better ensuring that the grease in the grease injector 232 completely enters the bearing raceway 401. After the grease in the grease injector 232 completely enters the bearing race 401, the driving motor 121 of the driver 12 is powered up again, and the grease is injected into the lubricating pipeline 20, and the circulation is performed until the lubrication of the bearing race 401 is completed.
When the bearing raceway 401 of the yaw bearing 400 is lubricated, the wind generating set does not need to be stopped, so that the power generation benefit of the wind generating set is not influenced on the basis of meeting the lubricating requirement of the bearing raceway 401.
In the present embodiment, the pressure detector 26 may be a pressure sensor, but may also be other types of detectors as long as it can detect the pressure of the lubrication line 20, and the pressure detector 26 may be specifically connected to the second branch 23 of the lubrication line 20. The controller may be a separately arranged control device, and of course, it may also be integrated on the master controller of the wind turbine generator system, and its position is not specifically limited.
When the master control of the wind generating set sends out a command for lubricating the gear ring 402 of the yaw bearing 400, the wind generating set is shut down feathering, the drive motor 121 of the driver 12 is powered on, and the first control valve 31 is powered on. Grease entering the lubrication line 20 may be delivered to the lubrication portion 222 through the first guide pipe 221 of the first branch 22, and lubrication of the ring gear 402 of the yaw bearing 400 is achieved by the lubrication portion 222. Because the lubricating part 222 is in the form of a gear, the working pressure of the lubricating part is much lower than that of the grease injector 232, so that the pressure of each pipeline of the lubricating pipeline 20 can be adjusted by adjusting the amount of the grease entering the lubricating pipeline 20 by the grease supply device 10 in a unit time, and it is ensured that the grease injector 232 does not work by the grease when a lubricating instruction of the gear ring 402 of the yaw bearing 400 is executed, so that the driving motor 121 of the driver 12 is not required to be powered off when the grease supply device 10 supplies oil to the lubricating pipeline 20, the driving motor 121 of the driver 12 can be powered on all the time, the driving pump 122 always supplies the grease to the lubricating pipeline 20, the lubricating part 222 of the first branch 22 can continuously obtain the grease and lubricate the gear ring 402, and the uniformity of lubrication of the gear ring 402 is ensured.
Although the wind generating set needs to be stopped when the gear ring 402 of the yaw bearing 400 is lubricated, the grease supply device 10 can continuously supply lubricating grease for the gear ring 402 of the yaw bearing 400, compared with the prior art, the lubrication of the gear ring 402 is uniform, the yaw bearing 400 runs stably, the lubrication speed of the whole circle of the gear ring 402 of the yaw bearing 400 can be increased, the stop time of the wind generating set is greatly shortened, and the power generation benefit of the wind generating set is better ensured.
In order to avoid the failure of the lubrication system 100 caused by the local blockage of the lubrication pipeline 20 during the process of executing the lubrication instruction to the gear ring 402 of the yaw bearing 400, as an alternative embodiment, an overflow branch 25 having an overflow valve 251 is further connected between the accommodating tank 11 and the lubrication pipeline 20, and when the first guide pipe 221, the second guide pipe 231, or the main pipeline 21 of the lubrication pipeline 20 is blocked, and the pressure detector 26 detects in advance and sends out a failure signal to notify the system of the failure and needs to be maintained as the pressure in the lubrication pipeline 20 reaches a preset pressure value. With the continuous rise of the pressure in the lubrication pipeline 20, when the pressure reaches the predetermined pressure relief value of the overflow valve 251, the overflow valve 251 is opened and the grease is caused to flow back to the accommodating box 11, so as to achieve the purpose of relieving the pressure in the lubrication pipeline 20, and avoid the first guide pipe 221, the second guide pipe 231 or the main pipeline 21 of the lubrication pipeline 20 from being broken due to the overhigh pressure.
The first control valve 31 in each of the above embodiments is described by taking a normally closed two-position two-way valve as an example, which is an optional manner, but not limited to this, it may also be a normally open two-position two-way valve, when a bearing race 401 lubrication instruction of the yaw bearing 400 is executed, the first control valve 31 may be powered on, and then the first branch path 22 is closed, so that it does not lubricate the gear ring 402, and the lubrication requirement of the yaw system can also be met.
Further, the first control valve 31 is not limited to a two-position two-way valve, and in some other examples, the first control valve 31 of the above embodiment may also be a one-way valve, which is communicated from the grease supply device 10 to the lubrication portion 222 in one way. Of course, other control valves may be used as long as the lubrication requirements of the yaw bearing 400 are met.
Fig. 3 shows a schematic structural diagram of a lubrication system 100 according to another embodiment of the present invention, please refer to fig. 3 together, the lubrication system 100 of this embodiment is substantially the same as the embodiment of the lubrication system 100 according to the embodiment shown in fig. 2, except that the valve assembly of the lubrication system 100 according to the embodiment of the present invention further includes a second control valve 32 disposed in the lubrication pipeline 20, the valve assembly further controls the on/off of the second branch 23 through the second control valve 32, and the second control valve 32 is specifically disposed in the second branch 23 of the lubrication pipeline 20 and is a normally open two-position two-way valve.
When the general control of the wind generating set sends out an instruction for lubricating the bearing raceway 401 of the yaw bearing 400, the first branch 22 is closed through the first control valve 31, the driving motor 121 of the driver 12 can be powered on, and lubricating grease is delivered to the lubricating pipeline 20. Since the second control valve 32 is a normally open two-position two-way valve, the grease entering the lubricating pipeline 20 can directly enter the grease injector 232 through the second control valve 32, so as to lubricate the bearing race 401, and when the bearing race 401 is lubricated, the power-on and power-off control of the actuator 12 is the same as that of the embodiment shown in fig. 2, which is not repeated here.
When the general control of the wind generating set sends out an instruction for lubricating the gear ring 402 of the yaw bearing 400, the first control valve 31 and the second control valve 32 can be powered on, the second branch 23 is closed through the second control valve 32, so that the lubricating grease entering the lubricating pipeline 20 does not enter the grease injector 232 and directly enters the lubricating part 222 of the first branch 22, that is, the lubricating grease pumped out by the grease supply device 10 is completely delivered to the gear ring 402, the lubricating speed and the uniform reliability of the lubrication of the gear ring 402 can be further improved, the downtime of the wind generating set is shortened again, and the power generation benefit of the wind generating set is improved.
It is understood that the second control valve 32 of the above embodiments is not limited to be a normally open two-position two-way valve, and alternatively, it may also be a normally closed two-position two-way valve, and when lubrication needs to be performed on the bearing race 401, the second control valve is powered on, so that the second branch 23 is opened, and the lubrication requirement of the bearing race 401 can also be met. Of course, the second control valve 32 is not limited to a two-position two-way valve, and may be another control valve, such as a check valve, which is communicated from the grease supply device 10 to the grease injector 232 in one direction.
Fig. 4 shows a schematic configuration of a lubrication system 100 according to a further embodiment of the present invention. Referring to fig. 4, it is understood that the manner of supplying all of the grease delivered from the grease supply device 10 to the first branch passage 22 or the second branch passage 23 is not limited to the embodiment shown in fig. 3, and the configuration shown in fig. 4 may be adopted.
As shown in fig. 4, the lubrication system 100 according to the embodiment of the present invention is substantially the same as the embodiment shown in fig. 3, except that the valve assembly according to the embodiment of the present invention includes a first control valve 31, and the first control valve 31 is a two-position three-way valve and is disposed on the main pipe 21 of the lubrication pipe 20, an inlet of the two-position three-way valve is connected to an outlet of the driving pump 122 of the grease supply device 10, and two outlets of the two-position three-way valve are respectively connected to a first guide pipe 221 of the first branch 22 and a second guide pipe 231 of the second branch 23, so that the first control valve 31 can control not only opening or closing of the first branch 22, but also control opening and closing of the second branch 23. Furthermore, the pressure detector 26 may be disposed on the main line 31 for better safety of the lubrication system 100.
When the lubrication system 100 provided by the embodiment needs to lubricate the bearing race 401, the first control valve 31 may be powered on or powered off, so that the second branch 23 is opened and the first branch 22 is closed, thereby realizing lubrication of the bearing race 401. When the gear ring 402 needs to be lubricated, similarly, the second branch 23 is closed and the first branch 22 is opened by powering on or powering off the first control valve 31, so that the gear ring 402 is lubricated.
Thus, the lubrication system 100 according to the above embodiments of the present invention includes the grease supply device 10, the lubrication line 20, and the valve assembly, and when the lubrication system 100 is used, the lubrication portion 222 of the first branch path 22 of the lubrication line 20 is engaged with the ring gear 402, and the grease in the grease supply device 10 is guided to the ring gear 402, so as to lubricate the ring gear 402.
