Correct sampling method for oil sample after treatment of hydraulic oil filter
2018/5/17 Viewers:
The adoption of oil samples is the basis of oil test. If the oil sample is not correct, it is not representative, and the result of the test is meaningless, so the correct sampling is the first link in the field of experiment and research. Both home and abroad have attached great importance to the work of sampling. The effect analysis of hydraulic oil filter, the analysis of cleanliness and the analysis of water content, the correct sampling rules and methods for oil samples are made at home and abroad.
Hydraulic oil has formulated the national standard for sampling method, named "sampling method for hydraulic oil", numbering GB7597- 87. The sampling method includes sampling tools, sampling methods, sampling locations, sampling quantities, and transportation and preservation of oil samples. Special attention should be paid to the different requirements for each sampling link and step in the sampling method and the special sampling (that is, the sampling of the water content and the gas content in the oil measurement). Sampling should be strictly observed in order to achieve correct and representative sampling. The oil quality test method is to determine the quality and performance of oil products. The indicators specified in the oil quality standards are closely related to the test methods adopted. Because certain indicators of oil, such as the test methods used, are different. Therefore, in order to obtain the relative comparability of results, a unified standard test method must be worked out. Therefore, in the standard test method, the principle of the method, the scope of application, the instrument used, the purity of the reagent, the test condition, the test procedure, the calculation formula and the precision are detailed, and the number of the test methods must be used in the oil quality standard to ensure the unification of the test results. One sex. The oil test method in China can be divided into three stages. That is, the national standard (GB) professional or industry standard (ZB., such as power DL) and enterprise standard (QB).
