Description

Technical Field

[0001] The present application relates to the field of industrial monitoring technology, and in particular to a monitoring device and method for an oil pump coupling of an auxiliary machine oil station. Background Art

[0002] Auxiliary oil station is an auxiliary device that provides lubrication and cooling for large mechanical equipment. It is widely used in the fields of electricity, petroleum, chemical industry, metallurgy, etc., especially in heavy industrial equipment that requires continuous lubrication (such as turbines, compressors and large pumping stations). Auxiliary oil station transports lubricating oil to key parts of the equipment (such as bearings, gears and couplings) through components such as motors and oil pumps to reduce friction and wear and extend the service life of the equipment.

[0003] The oil pump coupling is a mechanical device used to connect the motor and the oil pump shaft. Its main function is to transmit power so that the motor drives the oil pump to operate. The oil pump coupling is subjected to large torque when transmitting power. Long-term operation will cause aging and wear of the components and requires regular inspection. In the prior art, the inspection of the oil pump coupling generally requires opening the casing after shutdown and lifting the oil pump motor to see the oil pump coupling. The inspection process is relatively cumbersome. At the same time, when the oil pump coupling needs to be maintained or replaced, it is not easy to align the motor and the oil pump. Multiple attempts are required to ensure that the motor shaft and the oil pump shaft are on the same axis, which is time-consuming and laborious. In addition, during the inspection process of opening the casing, there is a risk of dust, oil or foreign objects entering the oil tank and contaminating the lubricating oil.

[0056] Second, a data processing module is connected to the sensor module and is used to receive and process the operating data of the sensor module, and to filter, denoise and analyze the data to extract the state characteristics of the oil pump coupling.

[0080] Optionally, after receiving the data, the data processing module performs the following processing on it:

[0081] Filtering: Preprocess the data using methods such as low-pass filters and Kalman filters to remove high-frequency noise.
