Description

Technical Field

[0001] The invention relates to a fan generator set, and in particular to a fan gear oil monitoring and processing system and method. Background Art

[0002] The gearbox is one of the core components of the wind turbine, and its operating condition directly determines the life of the wind turbine. Gear oil is the blood of the wind turbine gearbox. When the gearbox operates under complex working conditions for a long time, pitting, fatigue peeling, and wear occur on the tooth surface and bearings, which produce metal microparticles and merge into the gearbox oil. Therefore, oil monitoring is an effective means to diagnose the wear and operating condition of the wind turbine gearbox, and thus improve the safety and reliability of offshore wind power operation.

[0003] Wind turbine generator sets have extremely high requirements for stable operation and safety assurance of equipment. In particular, offshore platforms are production facilities in a relatively isolated environment, and their shipping and maintenance are greatly affected by environmental factors. The traditional offline detection method of gearbox oil sampling, laboratory inspection, and data summary and analysis is not suitable for the detection of wind turbine gearbox oil due to inconvenient sampling, long detection cycle, and susceptibility to the sampling and detection personnel's operation process. Online monitoring of oil quality is a line of defense for early warning in equipment maintenance, which can effectively solve the problem that fans are not suitable for traditional sampling and detection. If research on online monitoring system of wind turbine gearbox oil quality can be carried out, online monitoring of key indicators can be realized, and abnormal conditions of wind turbine gear oil can be discovered in time.

[0004] Fan gear oil filtration is an effective means to improve gearbox oil, especially wear conditions. Research on online filtration technology for fan gearbox oil is carried out to promptly deal with abnormal gearbox oil to avoid lubrication failure and subsequent wear on gear and bearing working surfaces, forming a vicious cycle between oil and components, thereby shortening the service life of gears.

[0005] There are ways to regenerate gear oil in the prior art, such as CN118775733A - online purification and regeneration method for fan gear oil, but there is no process for online monitoring of the gear oil. It can only be purified manually at regular intervals, and it is impossible to purify it in time. Since the wear of the gears and the changes in the gear oil are not linear, it is necessary to monitor the viscosity of the gear oil and the content of particulate matter in time for monitoring and then purify it in time.

[0006] Therefore, research on online monitoring and filtration technology of fan gearbox oil is carried out, and online monitoring and filtration treatment devices are developed to promptly detect abnormal conditions of fan gearbox oil, issue early warnings and take reasonable treatment measures to reduce unit wear and failure. This can not only improve equipment reliability and safety, but also save equipment operation and maintenance costs throughout its life cycle, extend the service life of gear oil, and ensure a good lubrication environment for the gearbox, which is of great significance to the high-performance and healthy operation of the fan gearbox throughout its life cycle.

[0007] The information disclosed in this background technology section is only intended to enhance the understanding of the overall background of the invention and should not be regarded as an acknowledgment or any form of suggestion that the information constitutes the prior art known to a person skilled in the art. Summary of the invention

[0008] The technical problem to be solved by the present invention is: how to solve the problem that the current fan gear oil is sampled offline for detection, the sampling is inconvenient, the detection cycle is long, the gear oil is not treated in time, and the gear service life is shortened.

In the present invention, the viscosity detection module includes a constant temperature device, which can improve the fluidity of the gear oil. In the present invention, the gear oil is filtered through a magnetic rod to filter most of the magnetic particles, the tiny mechanical particles are filtered through a mechanical filter, and the gear oil deterioration products are filtered through a fine filter, thereby improving the filtering effect.

[0023] The magnetic bar is mainly used to filter most magnetic particles. The mechanical filter can use a 2μm magnetic filter to filter tiny mechanical particles. The fine filter uses resin filtration to filter components such as gear oil degradation products. The magnetic bar is detachable and can be replaced in time.

[0024] Preferably, a second sampling valve and an exhaust valve are also connected to the third buffer zone.

[0046] In this embodiment, the fan gear oil monitoring and processing system also includes a heating and defoaming module 600, wherein the heating and defoaming module 600 is connected to the inlet end of the viscosity detection module 200 and the particle size detection module 300, and the heating and defoaming module 600 is used to eliminate bubbles in the gear oil entering the viscosity detection module 200 and the particle size detection module 300, thereby reducing the influence of bubbles on the detection accuracy.

The viscosity detection chamber 202 includes a constant temperature device; the constant temperature device can be a heating wire or a heating plate, etc., which is used to heat the gear oil flowing through the viscosity detection pipeline to improve the flow of the gear oil. The second temperature sensor 204 is used to detect the temperature. The viscosity detection sensor 203 can detect the viscosity and density parameters of the gear oil. The viscosity detection chamber 202 can set a constant temperature according to the detection requirements of the viscosity and density of the gear oil.

The third control valve 401 is used to start or close the quality detection pipeline. The quality sensor 402 can detect moisture, pH, etc.

[0050] The filtration module 500 includes a filtration pipeline (G), a fourth control valve 505 connected to the filtration pipeline, and a filtration tower 501; Figure 2 As shown, the filter module 500 also includes a first pressure gauge 506, a third temperature sensor 507, a first sampling valve 508, a first pressure relief valve 509, and a first oil drain valve 510 connected to the filter pipe in sequence along the oil inlet end.

A second sampling valve 515 and an exhaust valve 516 are also connected to the third buffer zone 513. The top of the filter tower 501 is connected to a fifth control valve 517.

[0051] The bottom of the filter tower 501 is provided with a support base for stability. The gear oil filtered by the magnetic rod 502, the mechanical filter 503, and the fine filter 504 has a certain turbulence, and the first buffer zone 511, the second buffer zone 512, and the third buffer zone 513 are respectively provided to stabilize the gear oil.

[0052] In this embodiment, the magnetic bar 502 is located at the bottom, the mechanical filter 503 is located in the middle, and the fine filter 504 is located at the top. The bottom-to-top setting can increase the filtering time of the gear oil and improve the filtering effect. The magnetic bar 502 is mainly used to filter most magnetic particles. The mechanical filter 503 can use a 2μm magnetic filter to filter tiny mechanical particles. The fine filter 504 uses resin filtration to filter components such as gear oil deterioration products.

If any indicator does not meet the use requirements, the filter module 500 is turned on to process the fan gear oil until all indicators return to normal.

[0057] It should be noted that detection and filtering can be performed at the same time, and the fan gear oil after filtering can be tested in real time to see if it meets the use requirements. It is also possible to close the control valve on the pipeline when a certain indicator does not meet the requirements, and then open it again after filtering for a period of time. If it still does not meet the use requirements after opening, continue filtering until all indicators meet the use requirements.
