Abstract

UN MÉTODO (100) PARA PROBAR UN DISPOSITIVO DE CIZALLE (42) PARA UN DISPOSITIVO DE SEPARACIÓN (40) QUE ABORDA EL PROBLEMA DE SIMULAR CON PRECISIÓN LA CANTIDAD DE CIZALLAMIENTO Y NÚMERO DE EVENTOS DE CIZALLAMIENTO CREADAS POR DICHO DISPOSITIVO DE CIZALLE, QUE COMPRENDE: LA INMERSIÓN (104) DE UNA PORCIÓN (103) DEL DISPOSITIVO DE CIZALLE EN UN TANQUE DE PRUEBA (101) PARA APLICAR UN CORTE; EL CÁLCULO (105) DE UNA PRIMERA VELOCIDAD DEL DISPOSITIVO DE CIZALLE PARA UN PRIMER PERIODO A UNA PRIMERA DISTANCIA PREDETERMINADA; EL<br /> CÁLCULO (107) DE UNA SEGUNDA VELOCIDAD DE LA PORCIÓN DEL DISPOSITIVO DE CIZALLE EN UNA SEGUNDA DISTANCIA PREDETERMINADA QUE CORRESPONDA A LA PRIMERA VELOCIDAD EN LA PRIMERA DISTANCIA PREDETERMINADA; EL CÁLCULO (109) DE LA DIFERENCIA DE TIEMPO ENTRE EL PRIMER PERIODO Y EL SEGUNDO PERÍODO PARA EL MOVIMIENTO DE LA PORCIÓN DEL DISPOSITIVO DE CIZALLE EN LA SEGUNDA VELOCIDAD; Y EL MOVIMIENTO (110) DE LA PORCIÓN DEL DISPOSITIVO DE CIZALLE EN LA SEGUNDA VELOCIDAD PARA EL SEGUNDO PERIODO Y LA DETENCIÓN (111) DEL MOVIMIENTO DE LA PORCIÓN DEL DISPOSITIVO DE CIZALLE PARA EL DIFERENCIAL DE TIEMPO. PARA SIMULAR EL CORTE APLICADO POR EL DISPOSITIVO DE CIZALLE EN LA PRIMERA DISTANCIA PREDETERMINADA EN EL PRIMER PERÍODO. ADEMÁS. LA PRESENTE INVENCIÓN, COMPRENDE UN APARATO (120, 230, 240) PARA PROBAR UN DISPOSITIVO DE CIZALLE (42).<br />  A METHOD (100) TO TEST A SHEAR DEVICE (42) FOR A SEPARATION DEVICE (40) THAT ADDRESSES THE PROBLEM OF PRECISELY SIMULATING THE AMOUNT OF SHEAR AND NUMBER OF SHEAR EVENTS CREATED BY SUCH DEVICE, WHICH COMES FROM CPRIZENDALE: THE IMMERSION (104) OF A PORTION (103) OF THE SHEAR DEVICE IN A TEST TANK (101) TO APPLY A CUT; THE CALCULATION (105) OF A FIRST SPEED OF THE SHEAR DEVICE FOR A FIRST PERIOD AT A FIRST PREDETERMINED DISTANCE; THE CALCULATION (107) OF A SECOND SPEED OF THE PORTION OF THE SHEAR DEVICE IN A SECOND PRESET DISTANCE THAT CORRESPONDS TO THE FIRST SPEED IN THE FIRST PREDETERMINED DISTANCE; THE CALCULATION (109) OF THE DIFFERENCE OF TIME BETWEEN THE FIRST PERIOD AND THE SECOND PERIOD FOR THE MOVEMENT OF THE PORTION OF THE SHEAR DEVICE AT THE SECOND SPEED; AND THE MOVEMENT (110) OF THE PORTION OF THE SHEAR DEVICE AT THE SECOND SPEED FOR THE SECOND PERIOD AND THE STOP (111) OF THE MOVEMENT OF THE PORTION OF THE SHEAR DEVICE FOR THE TIME DIFFERENTIAL. TO SIMULATE THE CUTTING APPLIED BY THE SHEAR DEVICE IN THE FIRST DEFAULT DISTANCE IN THE FIRST PERIOD. FURTHER. THE PRESENT INVENTION, INCLUDES AN APPARATUS (120, 230, 240) TO TEST A SHEAR DEVICE (42). <br />
