Description

[TECHNICAL FIELD]

[0001] The present application relates to the technical field of detection equipment, in particular to an electromagnetic monitoring online oil metal particle sensor calibration and metering system. [BACKGROUND]

[0002] The electromagnetic monitoring online oil metal particle sensor works on the principle of detecting the number of metal particles by calibrating the change of the magnetic field or magnetic flux in the detection area related to the number of particles when the oil flows through the sensor area with a magnetic field. Before first use or when system components change, the equipment needs to be calibrated to set system parameters and perform function checks. To verify the electromagnetic monitoring online oil metal particle sensor, fixed-size ferromagnetic or non-ferromagnetic particles are passed through the sensor, and the total number and distribution of particles passing through are recorded and counted, and the total number and distribution of particles read from the sensor are compared, so as to realize the parameter calibration and metering of the sensor.

[0003] When checking and metering the sensor, different sizes of ferromagnetic and non-ferromagnetic particles need to be passed through the pipeline of the sensor, which is generally passed through manually or mechanically. Manual passing has horizontal and vertical passing, horizontal passing needs a large volume of carrier and is not efficient, and the speed cannot be controlled. Vertical passing has fixed speed, but is not efficient.

[0004] Using a carrier to pass through, ferromagnetic and non-ferromagnetic particles are fixed on a strip, and the strip is driven to pass through the sensor by a mechanical drive. The mechanical drive method is better than manual passing, but based on the working principle of the sensor, the mechanical drive cannot use reciprocating operation, and needs to use a one-way circulation mode. In the circulation mode, the number of revolutions of the strip is calculated by calculating the stroke of the power wheel motor, and the total number of particles passing through each size is calculated according to the size and number of ferromagnetic and non-ferromagnetic particles on the strip. There are two driving methods for strip rotation, the first is to use a gear to drive, which needs to match the strip with the gear, but the irregular shape can easily cause background signal drift, affecting the detection performance; the wear of the strip can also affect the test results. The other is to use tension to drive, which needs to adjust the position of the tension wheel every time the test is performed, and the position reproducibility is poor, which cannot guarantee that the same position is reached every time, and even if the same position is reached, the tension applied will also have some deviation; which causes the rotation of the power wheel and the stroke of the strip to deviate, and after multiple circle tests, the calculation result will deviate from the theoretical result.

[0005] In addition, the strip test method needs to disassemble the connection parts of the strip every time the sensor is replaced, and the position of the strip needs to be adjusted after connection to avoid scratching and damaging the strip, resulting in loss of ferromagnetic and non-ferromagnetic particles. After multiple operations, the interface of the strip will be loose or contaminated by external impurities, affecting the test results. [SUMMARY]
