Description

Technical Field

[0001] The utility model relates to the technical field of oil sample detection and adjustment, in particular to an adjustment device for detecting the number of particles in an oil sample by the light extinction method. Background Technique

[0002] The light extinction method is a commonly used method for detecting the pollution degree of oil. It is mainly used to evaluate the particle pollution degree of oils such as lubricating oil and hydraulic oil. The basic principle of this method is that when light passes through an oil containing suspended particles, the particles will block the propagation of light, thereby affecting the transmission or scattering characteristics of light. By measuring the change in light intensity, the number and size of particles in the oil can be indirectly calculated.

[0003] The oil particle pollution detector is designed based on the principle of the light extinction method (light blocking method) and is used to detect the size and number of particles in a liquid. After installing viscosity and moisture sensors, the viscosity and water content of the oil can be monitored simultaneously. It can be widely used in the fields of aviation, aerospace, electric power, petroleum, chemical industry, transportation, port, metallurgy, machinery, automobile manufacturing, etc. to detect the solid particle pollution degree of oils such as hydraulic oil, lubricating oil, transformer oil (insulating oil), automotive engine oil (turbine oil), gear oil, engine oil, aviation kerosene, water-based hydraulic oil, etc. With the development of industrialization, to meet the lubrication and maintenance needs of high-precision and high-tech equipment, gradually judging the pollution detection level by judging the number of particles in the oil has become the mainstream. To achieve particle technology and classification using visual recognition, in addition to providing a good light source laser for receiving and emitting light and high-quality optical lenses and collimators, a device that can stably control and detect the light power of the light source and adjust the focal length of the detection sample cell and the optical lens is also the key to affecting the final detection accuracy and service life of the equipment. Therefore, an adjustment device for detecting the number of particles in an oil sample by the light extinction method is needed.

[0004] The existing adjustment device for detecting the number of particles in an oil sample by the light extinction method has certain drawbacks when in use. When the existing adjustment device for detecting the number of particles in an oil sample by the light extinction method is in use, there are problems with the power detection of the light source laser for receiving and emitting light and the later operation and maintenance, so it cannot meet people's needs.
