Why Is the Single-Acting Vane Pump Called a Non-Unloading Pump
Core Reason: Permanent Eccentricity In a standard single-acting vane pump: The cam ring and rotor maintain fixed eccentricity Pump displacement remains constant Flow is continuously delivered during rotation There is no built-in pressure unloading path Therefore, the pump does not automatically unload under pressure, so it is called a non-unloading vane pump.

Working Principle of a Single-Acting Vane Pump
Single-acting vane pumps are widely used in medium-pressure hydraulic systems due to their smooth flow output and stable operation. Understanding their working principle helps optimize system design and maintenance. 1.What Is a Single-Acting Vane Pump? A single-acting vane pump is a type of positive displacement pump that: • Uses a rotor mounted eccentrically inside a […]
