Miniaturized wet-heat type abrasion testing machine

Abstract

The invention discloses a miniaturized wet-heat type abrasion testing machine. The miniaturized wet-heat type abrasion testing machine comprises a support, an abrasion grinding wheel, a protection cover, a driving device, a constant pressure device used for providing constant pressure for a test specimen, a water collecting device and a wet-heat supplying device used for ensuring isothermal testing of the test specimen; the protection cover is installed on the top of the support, the abrasion grinding wheel and the driving device are installed in the support, the constant pressure device is arranged over the abrasion grinding wheel, and the water collecting device is arranged under the abrasion grinding wheel; the constant pressure device is provided with an installing hole for installing the wet-heat supplying device, a duckbill spray nozzle at the tail end of the wet-heat supplying device is installed in the installing hole, the central axis of the duckbill spray nozzle is perpendicular to the tangent line of the position, opposite to the duckbill spray nozzle, of the abrasion grinding wheel, and the driving device drives the abrasion grinding wheel to rotate to grind the test specimen. The miniaturized wet-heat type abrasion testing machine is simple in structure and convenient to use and has high practicability.

Description

technical field [0001] The invention relates to a miniaturized damp heat type abrasion testing machine. Background technique [0002] The wet heat abrasion tester is a special equipment for testing the wear level of vulcanized rubber under the condition of high temperature water and water vapor. At present, the abrasion machines commonly used in the rubber industry in the world are Acron Abrasive Machine and Roller Abrasive Machine, but they are all wear tests in dry air and normal temperature, and rubber cannot be tested under wet heat conditions with water or high temperature steam. As a result, although the wear amount of rubber in the general test has reached the index requirements, the test results and the actual use effect are greatly different due to changes in the actual use environment conditions, which cannot truly reflect the use conditions and meet the service life requirements. The existing wet heat abrasion testing machine is relatively large in size, and requ...

At present, the abrasion machines commonly used in the rubber industry in the world are Akron Abrasive Machine and Roller Abrasive Machine, but they are all wear tests in dry air and normal temperature, and rubber cannot be tested under wet heat conditions with water or high temperature steam.

As a result, although the wear amount of the rubber in the general test has reached the index requirements, the test results are greatly different from the actual use results due to changes in the actual use environment conditions, which cannot truly reflect the use conditions and meet the service life requirements.

The existing wet heat abrasion testing machine is relatively large in size, and requires a special protective cover, and the structure is more complicated
