2results about How to "Consistent lifespan" patented technology

This invention belongs to the field of methanol-to-hydrogen technology, specifically a methanol partial oxidation hydrogen production device, including a water storage section and a reaction section partially located within the water storage section. The reaction section includes a vapor inlet at one end and a reaction gas outlet at the other end, located inside and outside the water storage section. A reaction area is provided between the vapor inlet and the reaction gas outlet, located inside the water storage section. It is understood that this invention uses a horizontal annular reaction tube, effectively utilizing the width of the water storage section, resulting in a compact structure and stable placement. Multiple independent reaction chambers are built into the tube, each corresponding to a single oxygen source pipe and catalyst, improving reaction uniformity, ensuring consistent catalyst utilization and lifespan, and facilitating unified maintenance. Simultaneously, through the coordination of several inlet straight pipes, outlet straight pipes, and oxygen supply pipes, uniform vapor diffusion, centralized recovery of reaction gas, and uniform oxygen supply are achieved, ensuring the consistency of reactions in each reaction chamber. This parallel structure provides better reaction performance and higher efficiency compared to the traditional series method.

A service life testing device for pressure spring production comprises a testing platform, a testing box used for testing the service life of a pressure spring is fixedly installed on the testing platform, an opening facilitating taking and placing of the pressure spring is formed in the top of the testing box, and the opening is sealed through a sealing cover; transversely-arranged supporting shafts are inserted into the two sides of the testing box, a clamping gap used for being matched with a pressure spring is reserved between the supporting shafts, clamping plates matched with the pressure spring are fixedly installed on the supporting shafts in the testing box, clamping columns are further arranged on the clamping plates, and transverse driving devices are fixedly installed on the testing platform on the two sides of the testing box. The driving end of the transverse driving device is in transmission connection with a supporting shaft outside the test box; a heat exchange device is further installed in the test box, and a temperature and humidity instrument is further installed on the test box. By simulating the stress condition of the pressure spring in actual use, the service life of the pressure spring is tested, so that the durability and the service life of the pressure spring are evaluated.
