Question: Lubrication is a major event for fan equipment management. Our fan is sampling and detection on a regular basis. More responsibilities are on our side, but what's a good way to let us know the situation of the equipment quickly and easily? Answer: This is given to me, lubricating online monitoring, simple and direct, who knows who uses! In the context of the "double reduction", wind power generation is a typical scene of clean energy applications, and domestic and foreign countries have strongly supported the development of wind power. The cost of wind turbines is extremely high, and because it is generally located in remote areas, it is relatively scattered. At present, a considerable percentage is that of offshore wind power. The cost of one repair is more than one million. It is a great challenge for equipment management! In fact, a lot of sensors have been installed on the fan to help the owners manage the equipment remotely, such as the vibration sensor on the growth box, but due to this type of working conditions, the basic vibration will change, and it is still difficult for equipment management personnel to be difficult to change. Interpret the vibration diagram and find problems. In this case, online monitoring can solve many practical problems for the extremely critical growth box in the fan.
Maintenance is difficult in high -altitude environment, because the problem has not been found in time that causes the gear bearing to fail. The figure below shows a typical gear box system failure model. It can be seen that in the predictive maintenance area, the wear particles in oils are the first indicator of the failed to characterize the equipment, and the next step is vibration, noise, temperature rise, etc. If you can find abnormal wear of the equipment and take measures earlier, the more you can avoid the premature failure of the equipment and reduce the total cost of equipment maintenance.
The wear particles are not evenly distributed in the oil. In the traditional laboratory testing, the first is due to the typical problem of the sampling point. Great risk allows equipment managers to misjudge the use of the equipment. As shown in the figure below, a case in the United States and published in the 2016 journal. When a wind farm fan was sampled three times, there was no problem with the oil sample test report. Replace; and if the data monitored online, this problem can be avoided.
In the data of the 137 typhoon device of the entire wind farm, you can see a more amazing discovery. Among them, the laboratory offline detection of severe wi -weighed fans. In terms of regular maintenance endoscopy, on average, it is more than other reports than other reports. Fan that is not severely worn is better!
Online monitoring vs. laboratory test Regarding the online monitoring of the fan gear box, we recommend monitoring iron magnetic particles, water, viscosity (options), cleanliness (optional). At the edge, our system will calculate the lubrication health index LHI, and the red, yellow, green lights will be The form of form, facilitates first -tier equipment managers can directly know the condition of the equipment, and at the same time, through algorithms such as fitting, regression, you can indicate indicators such as the amount of wear, wear speed, etc., intuitive, clear! In terms of data transmission group network: It can transmit data to the SCADA system of the fan for centralized localization display, convenient and safe! Case 1: In the use of a fan, the wear speed and wear volume of the wear are obviously increased through algorithm signs, and after reducing power operation for a period of time, and after maintenance, the wear representation returns to normal.
Case 2: In August 2019, through real -time data+built -in algorithms, it can be seen from the figure below that the granules in a certain range are significantly increased, and the growth of other interval is not significant. The maintenance is indeed found that the oil level is low. After supplementing the new oil filtration, the wear is reduced.
Case 3: Although a certain wind farm fan, although there is no abnormality of the vibration, whether it is the iron magnetic particles that respond to the growth rate of the grinding particles, the amount of wear of the iron magnetic particles with the degree of wear or the degree of reaction wear has increased significantly. Gear bearings are damaged. After maintenance, the amount of wear and iron magnetic particles of iron magnetic particles and the cumulative grinding amount of iron magnetic particles have returned to normal.
