Structural form 4: Axial piston pump.
Driving mode 4: Hydraulic drive, specifically a reciprocating pump driven by hydraulic pressure.
Position of the pump shaft 4: Vertical.
材料 3: Usually made of cast iron, which has good wear resistance and compressive resistance.
変位: Based on the "25" in the model number, it is speculated that the nominal displacement may be 25 mL/r. しかし, this is not a definite value, and there may be differences among products from different sources.
プレッシャー: Referring to similar products, the rated pressure can generally reach around 25 MPA, and the maximum pressure may be around 30 MPA. しかし, the actual pressure range may vary depending on the application scenarios and designs.
Flow rate: The flow rate is related to the rotational speed and displacement. Under the rated rotational speed, the theoretical flow rate can be calculated by multiplying the displacement by the rotational speed. Assuming the rated rotational speed is 1500 – 2000 r/min and calculated based on the nominal displacement of 25 mL/r, the theoretical flow rate is approximately 37.5 – 50 l/min.
Rotational speed: Generally speaking, the rated rotational speed of this type of hydraulic pump may be in the range of 1500 – 2500 回転数, and the specific value depends on the supporting drive system and application requirements.
