Description

Technical Field

[0001] This utility model relates to the field of lubrication structure technology, specifically a centralized lubrication structure for a wind power system. Background Technology

[0002] Wind power systems are often composed of large and numerous mechanical components. Through the interaction and operation of these components, a complete wind power system is formed. However, while the machinery is operating, it needs lubricating oil to reduce the friction generated between the mechanical components, thereby reducing the friction and wear caused by the contact between the two mechanical components.

[0003] During the lubrication process, lubricating oil carries away the heat generated by the mechanical operation, causing the temperature of the lubricating oil itself to rise, reducing its working efficiency and service life. At the same time, when the lubricating oil settles, it will also produce certain flocculent substances, which will also affect the lubrication effect. Utility Model Content

[0004] The purpose of this invention is to provide a centralized lubrication structure for wind power systems to solve the problems mentioned in the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A centralized lubrication structure technical solution for a wind power system includes an oil tank, a cooling system, a single-cylinder filter, a high-pressure pump, a low-pressure pump, a motor, and a double-cylinder filter. The cooling system is connected to the low-pressure pump, the high-pressure pump is connected to the input end of the single-cylinder filter, the output end of the single-cylinder filter is connected to the motor pipeline, the cooling system is connected to the double-cylinder filter, the input end of the high-pressure pump is connected to the oil tank pipeline, the input end of the low-pressure pump is connected to the oil tank pipeline, and the output end of the double-cylinder filter is connected to the oil tank pipeline.

[0007] The oil tank, as the primary storage container, holds lubricating oil. The lubricating oil is then distributed according to lubrication requirements. A low-pressure pump sends the used lubricating oil from the tank to the cooling system, lubricating the system and lowering its temperature to prevent overheating and extend its lifespan. After cooling, the lubricating oil is filtered through a double-cylinder filter to prevent damage to its internal structure. A high-pressure pump then extracts the lubricating oil from the tank and sends it to a single-cylinder filter for further filtration. Finally, the filtered lubricating oil is sent to the motor for lubrication, reducing friction during operation and extending the motor's lifespan.

[0008] Furthermore, a drain port is provided on the fuel tank.

[0009] A drain outlet is provided to drain any water that may accumulate in the fuel tank due to operational reasons.

[0010] Furthermore, the cooling system is equipped with a water inlet, a water outlet, an oil inlet, and an oil outlet. The water inlet is used to deliver low-temperature coolant to the cooling system, the water outlet is used to send out high-temperature coolant from the cooling system, the oil inlet is connected to the output pipe of the low-pressure pump, and the oil outlet is connected to the input pipe of the dual-cylinder filter.

[0011] The low-temperature coolant supplied through the inlet creates a temperature difference with the high-temperature lubricating oil entering the cooling system through the oil inlet. This allows the low-temperature coolant to absorb heat from the high-temperature lubricating oil, lowering its temperature and thus extending its service life. The cooled lubricating oil is then discharged from the outlet and enters a dual-cylinder filter for further filtration. The coolant, now at a higher temperature, is discharged from the outlet.

[0012] Furthermore, there are two high-pressure pumps, one in the middle and one at the edge of the oil tank. Each high-pressure pump is equipped with a single-cylinder filter. There are four motors. The two motors adjacent to the oil tank are connected to the output pipes of the two single-cylinder filters on the high-pressure pump located in the middle. The two motors away from the oil tank are connected to the output pipes of the two single-cylinder filters on the high-pressure pump located at the edge. Each single-cylinder filter is equipped with a one-way valve.

[0013] By installing two single-cylinder filters on the high-pressure pump, the filtration efficiency of the lubricating oil is improved, allowing impurities to be removed in a timely manner and enhancing its lubricating performance. The high-pressure pump draws lubricating oil stored in the oil tank and sends it to the single-cylinder filters for filtration. The single-cylinder filters remove flocculent matter from the lubricating oil, and then the filtered lubricating oil is sent to the motor lubrication points for lubrication, improving the motor's efficiency. At the same time, the lubricating oil also carries away the heat generated during motor operation, playing a role in cooling the motor and extending its service life.

[0014] Furthermore, there are two low-pressure pumps, and the output pipes of the two low-pressure pumps are connected together, and the output pipes of the two low-pressure pumps are connected to the oil inlet pipes.

[0015] By setting up two low-pressure pumps, the rate at which the low-pressure pump draws lubricating oil from the oil tank is increased, allowing the lubricating oil to flow into the cooling system through the oil inlet at a faster rate, resulting in better cooling and thus improved lubrication efficiency.

[0016] Furthermore, an electronic valve is installed on the pipeline connected to the fuel tank.

[0017] An electronic valve is installed on the pipeline connected to the oil tank to control the flow of lubricating oil in the tank, thereby achieving reasonable distribution of lubricating oil and improving the lubrication capacity and efficiency of the lubrication system.

[0018] Compared with the prior art, the beneficial effects of this utility model are:

[0019] 1. The oil tank is connected to the cooling system, which can reduce the temperature of the lubricating oil and improve its service life.

[0020] 2. Equipped with a single-cylinder filter, which removes flocculent deposits and impurities from the lubricating oil, thereby improving the lubrication efficiency of the lubricating oil.

[0021] 3. The pipeline on the oil tank is equipped with an electronic valve, which controls the flow of lubricating oil to achieve precise control of the lubricated structure and improve lubrication efficiency. Attached Figure Description

[0027] Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0028] Example: Figure 1 - Figure 4As shown, this utility model provides a centralized lubrication structure technical solution for a wind power system. The lubrication structure includes an oil tank 1, a cooling system 2, a single-cylinder filter 3, a high-pressure pump 4, a low-pressure pump 5, a motor 6, and a double-cylinder filter 7. The cooling system 2 and the low-pressure pump 5 are connected. The high-pressure pump 4 and the input end of the single-cylinder filter 3 are connected. The output end of the single-cylinder filter 3 is connected to the motor 6 via a pipe. The cooling system 2 and the double-cylinder filter 7 are connected. The input end of the high-pressure pump 4 is connected to the oil tank 1 via a pipe. The input end of the low-pressure pump 5 is connected to the oil tank 1 via a pipe. The output end of the double-cylinder filter 7 is connected to the oil tank 1 via a pipe.

[0029] Oil tank 1 serves as the primary storage container for lubricating oil. The lubricating oil is stored in oil tank 1 and then distributed according to lubrication requirements. A low-pressure pump 5 sends the used lubricating oil from oil tank 1 to cooling system 2, lubricating the cooling system and lowering its temperature to prevent overheating and extend its lifespan. After cooling, the lubricating oil is filtered through a double-cylinder filter 7 to prevent damage to its internal structure from excessive heat. A high-pressure pump 4 extracts the lubricating oil from oil tank 1 and sends it to a single-cylinder filter 3 for further filtration. After filtration, the lubricating oil is sent to motor 6 for lubrication, reducing friction during motor operation and extending its lifespan.

[0030] like Figure 1 and Figure 4 As shown, the oil tank 1 is equipped with a drain outlet.

[0031] A drain outlet is provided to discharge any water that may accumulate in the oil tank 1 due to operational reasons.

[0032] like Figure 1 , Figure 2 and Figure 3 As shown, the cooling system 2 is equipped with a water inlet 21, a water outlet 22, an oil inlet 23, and an oil outlet 24. The water inlet 21 is used to deliver low-temperature coolant to the cooling system 2, the water outlet 22 is used to send out the high-temperature coolant in the cooling system 2, the oil inlet 23 is connected to the output pipe of the low-pressure pump 5, and the oil outlet 24 is connected to the input pipe of the dual-cylinder filter 7.

[0033] The low-temperature coolant is supplied to the cooling system 2 through the inlet 21, and a temperature difference is formed between the low-temperature coolant and the high-temperature lubricating oil entering the cooling system 2 through the oil inlet 23. This allows the low-temperature coolant to absorb the heat from the high-temperature lubricating oil, thereby reducing the temperature of the high-temperature lubricating oil and improving its service life. The lubricating oil with reduced temperature is discharged from the oil outlet 24 and enters the double-cylinder filter 7. The lubricating oil is filtered by the double-cylinder filter 7, and the coolant with increased temperature is discharged from the outlet 22.

[0034] like Figure 1 As shown, there are two high-pressure pumps 4, which are located in the middle and at the edge of the oil tank 1. Each high-pressure pump 4 is equipped with a single-cylinder filter 3. There are four motors 6. The two motors 6 adjacent to each other in the oil tank 1 are connected to the output pipes of the two single-cylinder filters 3 on the high-pressure pump 4 located in the middle. The two motors 6 far away from the oil tank 1 are connected to the output pipes of the two single-cylinder filters 3 on the high-pressure pump 4 located at the edge. Each single-cylinder filter 3 is equipped with a one-way valve.

[0035] By installing two single-cylinder filters 3 on the high-pressure pump 4, the filtration efficiency of the lubricating oil is improved, allowing the lubricating oil to be removed from impurities in a timely manner, thus improving the lubricating performance of the lubricating oil. The high-pressure pump 4 draws out the lubricating oil stored in the oil tank 1 and sends it to the single-cylinder filter 3 for filtration. The single-cylinder filter 3 filters out the flocculent matter present in the lubricating oil and then sends the filtered lubricating oil to the lubrication point of the motor 6 for lubrication, improving the efficiency of the motor 6. At the same time, the lubricating oil also carries away the heat generated by the motor 6 during operation, which plays a role in cooling the motor 6 and extending the service life of the motor 6.

[0036] like Figure 1 and Figure 4 As shown, there are two low-pressure pumps 5. The output pipes of the two low-pressure pumps 5 are connected, and the output pipes of the two low-pressure pumps 5 are connected to the oil inlet 23.

[0037] By setting two low-pressure pumps 5, the rate at which the low-pressure pumps 5 draw lubricating oil from the oil tank 1 is increased, so that the lubricating oil flows into the cooling system 2 through the oil inlet 23 at a faster rate, resulting in better cooling effect of the lubricating oil and thus improving lubrication efficiency.

[0038] like Figure 1 and Figure 4 As shown, an electronic valve is installed on the pipeline connected to oil tank 1.

[0039] An electronic valve is installed on the pipeline connected to oil tank 1 to control the flow direction of lubricating oil in oil tank 1, thereby achieving reasonable distribution of lubricating oil and improving the lubrication capacity and efficiency of the lubrication system.

[0040] The working principle of this utility model is as follows: Oil tank 1 stores lubricating oil. An electronic valve is installed on the pipeline connected to oil tank 1 to distribute lubricating oil to the structures requiring lubrication according to lubrication needs, thereby achieving reasonable distribution of lubricating oil and improving the lubrication capacity and efficiency of the lubrication system. A low-pressure pump 5 sends the used lubricating oil from oil tank 1 to cooling system 2 to lubricate the cooling system 2 and simultaneously lower the temperature of the lubricating oil to prevent overheating and thus reduce its service life. After cooling, the lubricating oil is filtered through a double-cylinder filter 7 to prevent damage to its internal structure from excessively high temperatures. A high-pressure pump 4 extracts the lubricating oil stored in oil tank 1 and sends it to a single-cylinder filter 3 for filtration, removing flocculent sediment from the lubricating oil in oil tank 1. Finally, the filtered lubricating oil is sent to the lubrication point of motor 6 for lubrication, thereby improving the operating efficiency of motor 6 and extending its service life.

[0041] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
