Embodiment Construction
[0012] The core of the present invention is to provide a method for testing the dehydration performance of the coalescing and separating filter element on lubricating oil, and the test result can quantitatively evaluate the dehydrating performance of the coalescing and separating filter element on lubricating oil.
[0013] In order to enable those skilled in the art to better understand the solutions of the present invention, the present invention will be further described in detail below with regard to specific embodiments.
[0014] In order to quantitatively evaluate the dehydration performance of the coalescing separation filter element for lubricating oil, it is necessary to conduct a standardized test. In order to avoid and reduce the influence of external factors on the test results as much as possible, so that repeated tests can obtain as consistent results as possible, the test should be used Special fuel tank and special test bench. Therefore, a kind of coalescing sep...

Abstract
The invention discloses a method for testing dewatering performance of a coalescence-separation filter core to lubricating oil. The method comprises an oil tank used for oil-water separation performance test and having effective volume of 300L, and a test bench device having rated flow of 20L / min and used for testing dewatering performance of the coalescence-separation filter core to the lubricating oil; before test, the lubricating oil for test is firstly formulated, the coalescence and / or separation filter core required by the test is arranged in a coalescence-separation chamber of the test bench device for dewatering performance of the lubricating oil, and during testing, timing sampling is performed and the water content of the lubricating oil is detected and recorded until the water content is lower than 5ppm; the test result is a dewatering performance curve of a certain coalescence filter core and / or the separation filter coil to certain lubricating oil under certain temperature condition.
Description
technical field [0001] The invention relates to a coalescence separation technology in the field of oil-water separation, in particular to a method for testing the dehydration performance of a coalescence separation filter element on lubricating oil. Background technique [0002] Coalescence separation technology is a new type of oil-water separation technology that appears with the development of new materials. It uses surface-treated glass fiber or polyester fiber as the coalescence and separation filter element of the coalescence medium, and utilizes the hydrophilic, Oleophilic properties, gradually coalesce the small water droplets in the oil into large water droplets, and the large water droplets settle to the bottom of the container under the action of gravity to achieve oil-water separation. At present, this technology has been applied in the separation of aviation fuel, gasoline, kerosene, diesel oil, light lubricating oil, benzene, alcohol and other chemical product...
