Presión nominal: These pumps are generally rated to operate at a working pressure of around 7 – 14 MPA (megapascales). 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.
Máxima presión: Las bombas normalmente pueden soportar una presión máxima de hasta 20 – 25 MPa para abreviar – operaciones a término o intermitentes. Sin embargo, 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 Velocidad de rotación
Velocidad de rotación nominal: The rated rotational speed of the HGP – 1A series pumps is commonly in the range of 1000 – 1800 revoluciones por minuto (rpm). This speed is optimized to achieve a good balance between flow rate generation, pressure development, y la longevidad de los componentes de la bomba..
Velocidad de rotación máxima: La velocidad de rotación máxima permitida generalmente es de aproximadamente 2000 – 2500 rpm. Exceeding this speed can result in increased wear, eficiencia volumétrica reducida, y posibles daños a la bomba debido a factores como fuerzas centrífugas excesivas y lubricación insuficiente.
2.4 Eficiencia volumétrica
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. Especificaciones mecánicas
3.1 Cuerpo de bomba
Material: The pump body is usually made of high – aleación de aluminio resistente. Aluminum alloy offers advantages such as light weight, good heat dissipation, y resistencia a la corrosión. The material is processed through precision casting or extrusion methods to ensure a high – quality and durable structure.
Dimensiones:
The overall dimensions vary depending on the specific model. Por ejemplo, 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 (P.EJ., PGH – 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.
