<p>A device for measuring high and low temperature durability of sealing member, which mainly comprises a main machine base (1), a high and low temperature testing box (2), a loading device, a test table (3), a pressure sensor (5) and a microcomputer (6) with a data processor. A servo motor (41) is used to load a test piece through a transmission mechanism (42), a vertical press block (43) and a loading head (44). A loading force is measured by the pressure sensor (5) and the measuring signal is fed back to the microcomputer (6) in real time, and a result is displayed in real time. Compared with a traditional durability tester or a fatigue tester the device has a controllable testing temperature, a long loading stroke and a large loading force range. The device is suitable for measuring durability of rubber sealing parts of various types at different temperature.</p> |
