Nenndruck: These pumps are generally rated to operate at a working pressure of around 7 – 14 MPA (Megapascals). This rated pressure is the value at which the pump can continuously and reliably provide hydraulic power to the system without excessive wear or damage.
Maximaler Druck: Die Pumpen halten typischerweise einem maximalen Druck von bis zu stand 20 – 25 MPa kurz – Dauer- oder intermittierende Operationen. Jedoch, operating at or near the maximum pressure for extended periods can lead to reduced pump life and an increased risk of component failure.
2.3 Drehzahl
Nenndrehzahl: The rated rotational speed of the HGP – 1A series pumps is commonly in the range of 1000 – 1800 Revolutionen pro Minute (Drehzahl). This speed is optimized to achieve a good balance between flow rate generation, pressure development, und die Langlebigkeit der Pumpenkomponenten.
Maximale Drehzahl: Die maximal zulässige Drehzahl liegt im Allgemeinen bei ca 2000 – 2500 Drehzahl. Exceeding this speed can result in increased wear, verringerter volumetrischer Wirkungsgrad, und mögliche Schäden an der Pumpe aufgrund von Faktoren wie übermäßigen Zentrifugalkräften und unzureichender Schmierung.
2.4 Volumetrischer Wirkungsgrad
The volumetric efficiency of these pumps is typically in the range of 85% – 92%. Volumetric efficiency represents the ratio of the actual flow rate of hydraulic fluid delivered by the pump to the theoretical flow rate. A higher volumetric efficiency indicates that a greater proportion of the input energy is used to move the fluid, rather than being lost due to internal leakage.
3. Mechanische Spezifikationen
3.1 Pumpenkörper
Material: The pump body is usually made of high – starke Aluminiumlegierung. Aluminum alloy offers advantages such as light weight, good heat dissipation, und Korrosionsbeständigkeit. The material is processed through precision casting or extrusion methods to ensure a high – quality and durable structure.
Abmessungen:
The overall dimensions vary depending on the specific model. Zum Beispiel, the HGP – 1A – F1R may have an approximate length of 100 – 120 mm, a width of 60 – 80 mm, and a height of 80 – 100 mm.
As the model number progresses (z.B., HGP – 1A – F8R), the dimensions may increase slightly. The exact dimensions are designed to provide a proper fit within the hydraulic system and to house the internal components effectively.
