Optimized Rotor Profiles for Efficient Fluid Pumps
Geared twin screw machines
These operate without metal-to-metal contact. This non-contact design significantly broadens their applicability, allowing them to handle a wide range of fluids, including non-lubricating, corrosive, or abrasive media. The rotors are typically one- or two-fluted, and unlike other screw configurations, the male and female rotors are identical in shape.
Triple screw rotors
These are designed with extremely tight clearance gaps, enabling highly efficient pumping through minimal internal leakage. These rotors operate in direct contact with one another and are not gear-driven. This direct engagement contributes to their compact design and performance, but also imposes specific limitations on the types of fluids they can handle.
Gear pumps
These use meshing gears to pump fluids and are commonly used in hydraulic systems and applications requiring precise fluid delivery. As the gears rotate, fluid gets trapped in the cavities between the gear teeth and the pump casing, it is then carried around the casing and expelled as the gears mesh together again. This ensures a steady flow of fluid, regardless of pressure changes.
Gear pumps with rounded tips offer notable advantages:
- Reduced Wear: The rounded gear tips help minimize sharp stress points during operation, reducing mechanical wear.
- Improved Efficiency: They deliver smoother fluid flow by reducing turbulence and improving volumetric efficiency.
- Lower Noise Levels: Rounded tips contribute to quieter operation by lessening vibrations caused by gear meshing.
- Enhanced Lifespan: By decreasing wear and improving the pump’s overall smoothness, rounded-tip gear pumps often have longer service lives.
Gerotors
These comprise of two gears: one gear fits inside another. As the gears turn, they create spaces that trap and push the fluid from one side to the other. Gerotors are popular in many machines because they are simple, reliable, and efficient.
