2. BOMBAS ROTATORIAS
Llamadas también rotoestáticas debido a que son máquinas
de desplazamiento positivo provistas de movimiento
rotatorio. Tienen muchas aplicaciones según el impulsor. El
fluido sale de la bomba en forma constante puede manejar
líquidos que contengan aire o vapor. Su principal aplicación
esla de manejar fluidos altamente viscosos lo que ninguna
otra bomba puede realizar y hasta puede carecer de

BOMBAS DE
ROTOR
MÚLTIPLE
Una bomba de rotor múltiple es
aquella en la cual los elementos
que giran lo hacen con respecto a
varios ejes.
Dentro de esta clase de bombas
se encuentran las siguientes:
- Engranes
- Lóbulos
- Balancines
- Tornillos

3. BOMBAS DEENGRANES
Se utilizan para casi todas las capacidades y presiones.
En muchos tipos, los engranes del rotor son automáticos
y no se necesita un engrane piloto. La forma más sencilla
emplea engranes de dientes rectos. El gran número de
dientes en contacto con la carcasa minimiza las fugas
alrededor de la periferia. La utilidad de los engranes de
dientes rectos está limitada porque atrapan líquido en el
lado de descarga en el punto donde se acoplan entre sí
los engranes, con lo cual resulta una operación ruidosa y
baja eficiencia mecánica, en particular a altas velocidades
de rotación.

conduce en trayectoria circular hacia afuera
y es exprimido al engranar nuevamente los

simples, dobles, o de involuta.
Utiliza dos engranes giratorios que se separan
en el lado de la succión de la bomba para
crear los vacíos permitiendo a la presión
atmosférica a forzar a el líquido a entrar en la
bomba. Los espacios entre los dientes del
engrane transportan entre las crestas el
líquido, de cada lado hacia el lado de la
descarga y al re-acoplarse los engranes se
descarga el líquido

5. BOMBA DETORNILLO
La transmisión de potencia hidráulica por medio de
bombas de tornillo se utiliza generalmente solo en los
submarinos. A pesar de ser baja en eficiencia y costosa,
la bomba de tornillo es conveniente para las altas
presiones (3000 psi), y entrega fluido con poco ruido o
pulsación de presión.
Esta bomba utiliza un tornillo helicoidal excéntrico que
se mueve dentro de una camisa y hace fluir el líquido
entre el tornillo y la camisa. Está específicamente
indicada para bombear fluidos viscosos con altos
contenidos de solidos que no necesiten removerse o
que formen espumas si se agitan.
