Pour point refers to the lowest temperature at which a cooled sample of a petroleum product can flow under specified test conditions, usually expressed in degrees Celsius. It is a key indicator for measuring the low-temperature fluidity of petroleum products, directly affecting the storage, transportation and usage performance of oil products in cold environments. For instance, diesel used outdoors in winter, if its pour point is too high, is prone to solidification in low-temperature environments, which can lead to poor fuel supply to the engine or even prevent it from starting. If the pour point of the lubricating oil is not up to standard, it may lose its lubricating effect at low temperatures, accelerating equipment wear.
The determination of the pour point of petroleum products should follow standardized methods to ensure the accuracy and comparability of the results. At present, the method stipulated in the GB/T3535 standard is widely adopted in China. Professional instruments are used to simulate specific cooling conditions and observe whether the sample can flow to determine its pour point. Different types of petroleum products (such as diesel, lubricating oil, fuel oil, etc.) and chemical products have different requirements for pour point due to their different uses and operating environments. Accurately determining the pour point is an important step in judging whether the product meets the usage standards.
The SD510-Q petroleum pour point tester is designed and manufactured in accordance with the requirements stipulated in the People's Republic of China standard GB/T3535, and is suitable for determining the pour point of petroleum products and chemical products in accordance with this standard. This instrument adopts compressor refrigeration, which features fast cooling speed and long service life. It is equipped with a small LCD display, ensuring good temperature control stability. It can simultaneously conduct two sets of tests (single slot with two holes), and has a high cooling efficiency. When conducting the measurement, the accompanying pour point test tube (a single-layer glass test tube with a metal sleeve) should be used. Manually tilt it 90 degrees to observe the fluidity of the sample to determine the pour point value.
Its main technical parameters are as follows: The working power supply is AC220V±10%, 50Hz; The temperature control range of the cold bath is from room temperature to -40℃, and the pour point measurement range is from room temperature to -25℃. The ambient temperature should be ≤30℃, the relative humidity ≤85%, and the power consumption should not exceed 1000W. The instrument measures approximately 380, 480 or 580mm and weighs 40kg.
