Abstract
UNA BOMBA DE VACIO CONTIENE DENTRO DE UNA CAMARA DE ASPIRACION, POR LA QUE CIRCULA AXIALMENTE UNA CORRIENTE, UNA PAREJA DE ROTORES DE DESPLAZAMIENTO (8) PERIFERICOS, EN ESPECIAL EN FORMA DE TORNILLO, QUE ENCAJAN UNO DENTRO DEL OTRO. ESTOS SE HAN ALOJADO EN VOLADIZO POR EL LADO DE LA PRESION Y SE HAN UNIDO CADA UNO A UN MOTOR DE ACCIONAMIENTO (35, 36). CADA ROTOR (8) FORMA, CON SU EJE CORRESPONDIENTE (20) Y UN CUERPO DE COJINETE ESTACIONARIO (7), QUE ENCIERRA CON EL EJE LOS COJINETES (21, 22), UNA UNIDAD CONSTRUCTIVA QUE PUEDE EXTRAERSE TOTALMENTE DEL RESTO DE LA CARCASA (3). A ELLA PERTENECE TAMBIEN DE FORMA PREFERIBLE EL ROTOR (35) DEL MOTOR DE ACCIONAMIENTO.
