Description

Technical Field

[0001] This utility model relates to the field of oil analysis technology, and more specifically, to a high-capacity quartz combustion tube for oil analysis. Background Technology

[0002] Oil product analysis refers to a series of chemical, physical, and biological tests performed on petroleum products (such as gasoline, diesel, and lubricating oil) to determine whether their quality and performance meet specific standards and specifications. These analyses are crucial for ensuring the safety, reliability, and effectiveness of oil products.

[0003] A search revealed an existing patent (publication number: CN220983213U) disclosing a high-capacity quartz combustion tube for oil analysis, relating to the field of oil analysis. The tube includes a tube body and a cap. An inner combustion tube is installed on the inner wall of the tube body. An air inlet pipe is installed at the bottom of the inner combustion tube, with its bottom end penetrating the tube body. A carrier gas preheating pipe is installed on the inner wall of the air inlet pipe, penetrating the inner combustion tube. An oxygen preheating pipe is installed on one side of the inner combustion tube, with its bottom end penetrating the tube body. This invention, by setting a cap, allows the first sealing ring to be inserted into the inner combustion tube of the high-capacity quartz combustion tube body through a rotating sleeve connected to the cap body. The toothed strip ring provides elasticity and a sealing effect, facilitating a close fit to the inner combustion tube. Simultaneously, a rubber sealing sleeve connected to the cap body covers the outer wall of the tube body, increasing the stability of the cap installation. This allows for quick installation and disassembly of the cap and tube body connected to the outlet cap, facilitating subsequent use in oil analysis and allowing for easy cleaning after use.

[0004] During use, the carbon deposits generated by internal combustion tend to adhere to the outer surfaces of the carrier gas preheating pipe and the oxygen preheating pipe, making them difficult to disassemble and clean, which leads to a gradual deterioration in the preheating effect.
