Description

Technical Field

[0001] This application belongs to the technical field of thermal power generation equipment, and in particular relates to a wind turbine oil station. Background Technology

[0002] In thermal power plants, wind turbines are the core power units for conveying flue gas, air, and desulfurization and denitrification media, significantly impacting power generation efficiency, environmental compliance, and system stability. The wind turbine oil station, a crucial component, supplies oil to the bearing housings, hydraulic cylinders, and motor bearings of the wind turbine. The oil station handles a large volume of oil, and during operation, the high ambient temperature causes the lubricating oil temperature within the oil station to rise, potentially leading to bearing overheating, alarms, or even turbine shutdown. Furthermore, the oil supplied to the wind turbine oil station must be kept clean to ensure the long-term reliable operation of the wind turbine.

[0003] Traditional wind turbine oil stations typically arrange the oil filter and cooler as two separate devices or functional modules within the oil circuit system. In existing technology, the general operating mechanism is as follows: when the oil temperature in the wind turbine oil station is high, a cooling fan or cooler is added; when the oil quality is substandard, oil filtration is performed. This approach does not integrate oil filtration and cooling functions. Adding oil filtration and cooling devices results in complex piping, requiring additional connecting pipes, valves, and joints, increasing the complexity of the oil circuit system and potential leakage points. Installation and maintenance are inconvenient, and the efficiency and cost of installing, disassembling, and maintaining two separate devices are low. Furthermore, there are issues with coordination; the control of oil filtration and cooling functions is relatively independent, making coordinated optimization difficult.

[0004] Therefore, developing a wind turbine oil station to address the technical shortcomings of existing wind turbine oil stations, such as inconsistent installation and maintenance and poor coordination between the oil filter and cooler, has become an urgent problem for those skilled in the art. Utility Model Content

[0005] Therefore, it is necessary to address the technical shortcomings of existing fan oil station technologies, such as the inconsistency in installation and maintenance and poor coordination of the oil filter and cooler. A new fan oil station should be provided.

[0006] This application provides a wind turbine oil station, which includes: an oil station body, a filter assembly, and a cooling assembly. The filter assembly and the cooling assembly are connected to the oil return pipeline of the oil station body. The oil in the oil return pipeline passes through the filter assembly and the cooling assembly in sequence and then returns to the oil tank of the oil station body.

[0007] In one embodiment, the fan oil station further includes a control component, which includes a differential pressure sensor, a temperature sensor, and a controller.

[0011] In one embodiment, the filtration assembly further includes a plurality of pumps connected to the coarse filtration section, the fine filtration section, the magnetic adsorber, and the high-precision filtration section, respectively.

[0012] In one embodiment, the cooling component is selected from any one or more of a plate heat exchanger, a shell-and-tube heat exchanger, or an air-cooled radiator.

[0013] In one embodiment, the plate heat exchanger includes two liquid cooling sections arranged in parallel.

[0014] In one embodiment, the filter assembly and the cooling assembly are arranged to be stacked vertically.

[0015] In one embodiment, the wind turbine oil station further includes a housing, with the filter assembly and the cooling assembly disposed inside the housing.

[0016] In summary, this application provides a wind turbine oil station, comprising: a main body, a filter assembly, and a cooling assembly.

[0025] To provide a clear and complete description of the wind turbine oil station provided in the embodiments of this application, the following will be combined with... Figure 1 A structural diagram of a stroke engine oil station, briefly explaining the working process of the main body of the oil station.

[0026] When the wind turbine oil station is working, inside the main body of the oil station, the first working oil pump 12 and the second working oil pump 13 draw oil from the oil tank 11 and then enter the various structures of the wind turbine equipment that need lubrication. At the oil outlets of the first working oil pump 12 and the second working oil pump 13, a first check valve 14 and a second check valve 15 are respectively installed to prevent oil from flowing back into the oil tank. During oil return, the oil from the various structures of the wind turbine equipment that need lubrication enters the return oil pipeline and returns to the oil tank 17.

[0027] Please see Figure 1This application provides a wind turbine oil station, including: an oil station body 1, a filter assembly 2, and a cooling assembly 3. The filter assembly 2 and the cooling assembly 3 are connected to the oil return pipeline of the oil station body 1. The oil in the oil return pipeline passes through the filter assembly 2 and the cooling assembly 3 in sequence before returning to the oil tank of the oil station body 1. The wind turbine oil station provided by this application solves the technical defects of existing wind turbine oil stations, such as inconsistent installation and maintenance and poor coordination between the oil filter and the cooler.

[0028] In the wind turbine oil station provided in this embodiment, a filter assembly 2 and a cooling assembly 3 are connected to the return oil pipeline of the main body 1. These components sequentially filter and cool the oil in the return oil pipeline. The filter assembly 2 and the cooling assembly 3 are designed in series, providing better synergy and effectively ensuring the quality of the oil returning to the oil tank. When processing the oil in the return oil pipeline, filtration by the filter assembly 2 prevents the oil from clogging the cooling assembly 3 and the pipeline during cooling, further improving the overall reliability of the wind turbine oil station and reducing its maintenance frequency and costs.

[0029] This application provides a wind turbine oil station that directly connects both the filter assembly 2 and the cooling assembly 3 to the return oil pipeline, effectively optimizing the oil circuit design. Through this structural optimization, oil flow resistance and system pressure loss are effectively reduced, further improving the working efficiency of the wind turbine oil station. Simultaneously, the optimized oil circuit structure reduces the use of elbows, joints, and other components, decreasing potential leakage points and lowering the probability of oil leakage.

[0030] To further optimize the technical solution, the fan oil station provided in this application embodiment also includes a control component, which further includes a differential pressure sensor, a temperature sensor, and a controller. The differential pressure sensor is respectively installed at the oil inlet and outlet of the filter assembly 2, and the temperature sensor is installed at the oil inlet of the cooling assembly 3. The differential pressure sensor and the temperature sensor are electrically connected to the controller, which is electrically connected to the cooling assembly 3 to control the start and stop of the cooling assembly 3. The differential pressure sensor can detect the pressure difference between the oil inlet and outlet of the filter assembly 2. The differential pressure sensor is electrically connected to the controller. If the differential pressure detection result of the differential pressure sensor exceeds a preset value, the controller issues a prompt signal to remind the operator to replace the filter element of the filter assembly 2. The temperature sensor detects the temperature of the oil entering the cooling assembly 3. The temperature sensor is electrically connected to the controller. If the oil temperature is higher than a preset value, the controller sends a signal to the cooling assembly 3 to start the cooling assembly 3 to cool the oil. By monitoring the filter assembly 2 through the control component, the good filtration effect of the filter assembly 2 is effectively ensured; and by controlling the start and stop of the cooling assembly 3 through the control component, the energy waste caused by starting the cooling assembly 3 when cooling is not required is avoided.

[0031] To further optimize the technical solution, while ensuring the good filtration effect of the filter assembly 2, this application embodiment also aims to improve the filtration efficiency of the filter assembly 2 and reduce the component cost of the filter assembly 2. The filter assembly 2 includes a coarse filter section 21 and a fine filter section 22. The oil entering the filter assembly 2 passes through the coarse filter section 21 and the fine filter section 22 sequentially. The coarse filter section 21 has a filtration diameter of 30-100 micrometers, and the fine filter section 22 has a filtration diameter of 3-10 micrometers. By dividing the filter assembly 2 into a coarse filter section 21 and a fine filter section 22, the coarse filter section 21 filters large-diameter impurities, and the fine filter section 22 filters small-diameter impurities. This improves the filtration efficiency of the filter assembly 2 and effectively reduces component costs compared to using a small-diameter filter alone.

[0032] In a wind turbine oil station provided in this embodiment, the filter assembly 2 further includes: a magnetic adsorber and / or a high-precision filter section 23. The magnetic adsorber is located at the front of the coarse filter section 21, and the oil entering the filter assembly 2 passes through the magnetic adsorber and then enters the coarse filter section 21. The high-precision filter section 23 is located at the rear of the fine filter section 22, and the oil flowing out of the fine filter section 22 enters the high-precision filter section 23. The filtration diameter of the high-precision filter section 23 is 1-3 micrometers. The magnetic adsorber can remove metallic impurities from the oil, and the high-precision filter section 23 can further filter the oil, optimizing the filtration effect.

[0033] To further optimize the technical solution, while ensuring good filtration effects of the coarse filtration section 21, fine filtration section 22, and high-precision filtration section 23, the cost of components is also reduced. In the technical solution provided in this application embodiment, the coarse filtration section 21 is selected from any one or more of filter screen, filter paper cylinder, and metal filter element; the fine filtration section 22 is selected from any one or more of filter screen, filter paper cylinder, and metal filter element; and the high-precision filtration section 23 is selected from any one or more of filter screen, filter paper cylinder, and metal filter element.

[0034] To further optimize the technical solution and accelerate the flow rate of oil through the filter assembly 2 and improve the working efficiency of the filter assembly 2, the filter assembly 2 in the technical solution provided in this application embodiment further includes: multiple pumps, which are respectively connected to the coarse filter section 21, the fine filter section 22, the magnetic adsorber and the high-precision filter section 23.

[0035] In a fan oil station provided in this embodiment, while ensuring the cooling effect of the cooling component 3 on the oil, the design requirements of the cooling component 3 being compact and small are also taken into account. The cooling component 3 is selected from any one or more of the following: plate heat exchanger, shell-and-tube heat exchanger, or air-cooled radiator. The plate heat exchanger or shell-and-tube heat exchanger can cool the oil by circulating a cooling medium, specifically water or other coolant. When the operating environment temperature of the fan oil station is low, an air-cooled radiator can also be used for cooling.

[0036] To effectively ensure the plate heat exchanger provides good cooling for the oil, the plate heat exchanger provided in this application includes two parallel liquid cooling sections 31.

[0037] To further optimize the technical solution and reduce the footprint of the power components and cooling components 3, the filter components 2 and cooling components 3 are stacked vertically in the technical solution provided in this application embodiment.

[0038] The fan oil station provided in this application embodiment further includes: a housing, with a filter assembly 2 and a cooling assembly 3 disposed inside the housing. The housing can provide a certain degree of enclosure and protection for the filter assembly 2 and the cooling assembly 3, preventing the external environment from affecting them.

[0039] In summary, this application provides a wind turbine oil station, comprising: a main body, a filter assembly, and a cooling assembly. The filter assembly and the cooling assembly are connected to the return oil pipeline of the main body. The oil in the return oil pipeline passes sequentially through the filter assembly and the cooling assembly before returning to the oil tank of the main body. In the technical solution provided by this application, the filter assembly and the cooling assembly are connected in series to the return oil pipeline of the wind turbine oil station, sequentially filtering and cooling the oil. This eliminates the need for repeated installation of the cooling assembly and its piping and equipment, reducing workload, lowering the potential risk of oil leakage from connected equipment and pipelines, improving the reliability of the wind turbine oil station, and fundamentally solving the problems of high oil temperature and substandard oil quality in wind turbine oil stations.
