Description

Technical Field

[0001] This utility model relates to the field of oil kinematic viscosity testing technology, and in particular to a portable oil kinematic viscosity tester. Background Technology

[0002] Oil testing is an important part of routine machine inspection. The purpose of analyzing and testing oil in use is, firstly, to identify the degree of deterioration and causes of contamination of the oil in the equipment by regularly monitoring the main physicochemical indicators of the oil in use, and to evaluate the condition of the oil in the equipment.

[0003] Kinematic viscosity, as one of the most important indicators of lubricating oil, reflects the oil's flowability. Both excessively high and low kinematic viscosity can affect equipment performance and even cause mechanical accidents. During the start-up, shutdown, or abnormal operation of machinery, fuel oil may seep into the oil system, leading to a decrease in kinematic viscosity. To ensure the normal operation of machinery, it is necessary to periodically test the kinematic viscosity of the oil.

[0004] Traditional oil testing requires regular sampling and analysis, necessitating manual on-site collection of oil samples, which are then sent to a laboratory for analysis. The results are then used to assess the kinematic viscosity of the oil in the machinery.

[0005] Research on methods for kinematic viscosity testing is constantly evolving, and the technology is becoming more mature. Traditional oil measurement methods have high requirements for the experimental environment, are complex to operate, and are costly. They can usually only be measured in the laboratory, which has significant limitations, a large time lag, and makes it difficult to judge the working condition of mechanical parts in a timely manner. In addition, the workload is large, making it impossible to promote them on a large scale.

[0006] In conclusion, developing an oil kinematic viscosity analyzer that is simple in structure, low in cost, has good detection effect, is versatile and easy to carry is an urgent technical problem that needs to be solved at present. Utility Model Content

[0007] To address the aforementioned technical problems in oil kinematic viscosity testing, this invention provides a portable oil kinematic viscosity meter that is ingeniously designed, simple in structure, low in cost, provides good testing results, is highly versatile, easy to carry, and convenient to use.

[0008] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows: a portable oil kinematic viscosity meter, including a processing module, a kinematic viscosity meter, an oil recovery bottle, a constant temperature device, a battery module, a small pump, an oil storage tank, a box body, and a box cover. The processing module is located on the left side of the box body, and the constant temperature device is located in the middle of the box body. The constant temperature device is a hollow cylindrical structure. The kinematic viscosity meter is located inside the cylindrical structure. The kinematic viscosity meter includes an oil inlet cup and a capillary channel. An oil inlet is provided above the oil inlet cup on the box cover. The upper and lower ends of the capillary channel are connected to the oil inlet cup and the oil storage tank, respectively. The oil recovery bottle is located at the upper right end of the box body, the battery module is located below the oil recovery bottle, and the small pump is located on the oil storage tank. The small pump connects the oil storage tank and the oil recovery bottle through a pipeline and sends the tested oil into the oil recovery bottle for recovery.

[0014] Second, high measurement accuracy: The measurement accuracy is highly consistent with that of relevant laboratory instruments and equipment, and it provides the kinematic viscosity of the oil at 40°C (measured value) and 100°C (calculated value).

[0015] Third, multi-point calibration: using standard oil, precise calibration is performed on a specific viscosity range, which effectively improves the detection accuracy of oils of various kinematic viscosity grades.
