Problems solved by technology
[0002] At present, the pour point of petroleum and petroleum products is determined by putting the sample into a test tube and cooling it to a certain temperature, tilting it, and observing whether the sample of petroleum and petroleum products flows with the naked eye to determine the pour point. It leads to a large human error, and when the pour point is not measured at a higher temperature, the samples will be placed in a cold bath at a lower temperature one by one to repeat the above observation process until the pour point is determined, so multiple cold baths are required , the operation is extremely cumbersome

The present invention discloses a determinator, which comprises a body, a controller and a cold bath, and is characterized in that a test tube is arranged inside the cold bath, the top portion of the cold bath is provided with a cold trap cover, a refrigerator is arranged outside the cold bath, the cold trap cover is provided with a gas inlet hole, the gas inlet hole is connected to an air compression pump through a gas inlet pipe, the gas inlet pipe is provided with an electromagnetic valve, and the piston of the air compression pump is connected to a stepping motor. According to the present invention, with the determinator, the pour points of the petroleum and the petroleum product can be rapidly and accurately determined.
Description
technical field [0001] The invention relates to a measuring instrument. Background technique [0002] At present, the pour point of petroleum and petroleum products is determined by putting the sample into a test tube and cooling it to a certain temperature, tilting it, and observing whether the sample of petroleum and petroleum products flows with the naked eye to determine the pour point. It leads to a large human error, and when the pour point is not measured at a higher temperature, the samples will be placed in a cold bath at a lower temperature one by one to repeat the above observation process until the pour point is determined, so multiple cold baths are required , the operation is extremely cumbersome. Contents of the invention [0003] In order to solve the above-mentioned existing shortcomings, the main purpose of the present invention is to provide a practical measuring instrument, which can accurately and quickly measure the pour point of petroleum and petrol...
