A method and apparatus for testing a shearing device

摘要

A method (100) of testing a shearing device (42) for a separation device (40), comprises: submerging (104) a portion (103) of the shearing device in a test tank (101) to apply shear; calculating (105) a first speed of the shearing device for a first time period at a first predetermined distance; calculating (107) a second speed for the shearing device portion at a second predetermined distance that corresponds to the first speed at the first predetermined distance; calculating (109) the time difference between the first time period and a second time period for moving the shearing device portion at the second speed; and moving (110) the shearing device portion at the second speed for the second time period and stopping (111) movement of the shearing device portion for the time difference, to simulate the shear applied by the shearing device at the first predetermined distance over the first time period.
