Principle of oil cleanliness detector (Method of using oil cleanliness detector)

Oil cleanliness detector is a device used to detect the content of particulate contaminants in oil. It uses optical or laser scattering technology to quickly and accurately measure tiny particles or solid impurities in oil. Cleanliness detector can be widely used in the detection of lubricating oil, hydraulic oil, transformer oil and other oil, used to assess the quality and life of the oil, predict the health status of the equipment, improve the reliability and life of the equipment, and ensure the safety and stable operation of industrial production.

First, oil cleanliness detector principle

The principle of the oil cleanliness detector is mainly to assess the cleanliness of the oil by detecting the number and size of particles or solid impurities in the oil. The cleanliness of the oil is very important to ensure the normal operation of the equipment and extend the service life of the equipment, because the particles and impurities in the oil can lead to equipment wear, pump blockage, oil seal wear and other problems.

The working principle of the oil cleanliness detector is usually divided into two common methods.

1, laser scattering method. This method uses a laser beam to shine through the area of the oil sample, which scatters when the laser encounters particles or solid impurities in the oil. The oil cleanliness detector measures the intensity and Angle of these scattered lights to calculate the number and size of particles in the oil based on the scattering characteristics.

2. Optical microscopy. This method detects particles and impurities in the oil by placing the sample under a microscope and using the magnification function of the microscope. Inspectors look at the number, size and shape of particles in the oil, and then assess the cleanliness of the oil according to certain criteria.

Through the above two methods, the oil cleanliness detector can quickly and accurately assess the cleanliness of the oil, and provide corresponding reports and data to help users take timely measures to ensure the normal operation of the equipment. Different oil cleanliness detectors may use slightly different principles and techniques, but the overall principle is to assess the cleanliness of the oil by detecting particles or impurities.

Second, the use of oil cleanliness detector

The use of the oil cleanliness detector can be operated according to the specific instrument model and the manual provided by the manufacturer. In general, the following are the steps of the general oil cleanliness detector method.

1. Prepare. Ensure that the oil cleanliness tester is installed and connected to the power supply. Check whether the tester is in normal working condition.

2. Collect samples. Collect samples from the equipment or oil to be tested to ensure that the sample collection process to avoid external contamination to ensure the accuracy of the test.

3. Sample treatment. According to the instrument requirements, the sample is pretreated, which may include filtration, dilution, or other specific operations.

4. Sample loading. Load the treated sample into the sample loading area or tank of the oil cleanliness detector.

5. Start the instrument. Turn on the power supply of the instrument and start the test procedure according to the instruction manual of the instrument.

6. Testing process. The instrument begins to detect particles or impurities in the sample through laser scattering and microscope observation according to the principle and method adopted.

7. Result analysis. After the test is completed, the instrument will automatically display or output the test result, and the cleanliness evaluation and analysis will be conducted according to the result.

8. Data recording and reporting. Record test results in relevant reports or data tables for subsequent analysis and comparison.

9. Maintenance and cleaning. After the test is completed, the instrument is maintained and cleaned accordingly to ensure the normal operation and long-term stability of the instrument.

Different oil cleanliness detectors may have different operating processes and methods of use, so be sure to carefully read the operating manual and instruction manual of the instrument before use, and follow the operating steps provided by the manufacturer to correctly use and operate the instrument. At the same time, attention should also be paid to the maintenance and maintenance of the instrument to ensure its long-term stable and accurate operation.
