1. Technical parameters
Displacement: According to the characteristics of the T67 series, the geometric displacement corresponding to “B25” in the model is approximately 79.3mL/r, and that corresponding to “B14” is approximately 46mL/r.
The maximum working pressure of the T67 series vane pump can reach 280bar (28MPa).
Rotational speed range: Generally 600-2800rpm.2. Working Principle
The T67 series vane pump belongs to the double-acting vane pump. When the rotor rotates clockwise, driven by the transmission shaft, the blades, under the action of centrifugal force and pressure oil, have their tips tightly adhering to the inner surface of the stator. The stator surface is composed of eight parts: two long-radius arcs, two short-radius arcs, and four transition curves, and the stator and rotor are concentric. During the rotation of the rotor, the volume of the sealed working chamber gradually increases at the upper left and lower right corners, forming an oil absorption zone. The oil is drawn in through the oil absorption window on the oil distribution plate. At the lower left and upper right corners, the volume gradually decreases, forming the oil pressure zone, and the oil is pushed out through the oil pressure window on the oil distribution plate. With each revolution of the rotor, each sealed working chamber performs two oil suction and two oil pressure actions respectively.

3. Product features and advantages
High working pressure: The maximum pressure of small-sized shell pumps can reach 320bar, which can reduce installation costs. If used at a reduced pressure, the working life can be prolonged.
High efficiency: The typical volumetric efficiency is higher than 94%, which can reduce heat generation. The typical mechanical efficiency value is higher than 94%, reducing power loss.
Wide speed range: The speed range is 600-3600rpm. Combined with a large-displacement pump core, a smaller-sized housing can be used to form a large-displacement low-noise pump.
Small pressure pulsation: The pressure pulsation is ±2bar, which reduces pipeline noise and can extend the service life of other components in the circuit.
Strong anti-pollution ability: Utilizing blade technology, it has a strong resistance to solid particle pollution, ensuring a long service life of the pump.
Low maintenance cost: By adopting the concept of pump core components, the maintenance cost is reduced several times.

4. Usage functions and purposes
