Rated Pressure: 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.
Maximum Pressure: The pumps can typically withstand a maximum pressure of up to 20 - 25 MPa for short - term or intermittent operations. However, 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 Rotational Speed
Rated Rotational Speed: The rated rotational speed of the HGP - 1A series pumps is commonly in the range of 1000 - 1800 revolutions per minute (rpm). This speed is optimized to achieve a good balance between flow rate generation, pressure development, and the longevity of the pump components.
Maximum Rotational Speed: The maximum allowable rotational speed is generally around 2000 - 2500 rpm. Exceeding this speed can result in increased wear, reduced volumetric efficiency, and potential damage to the pump due to factors such as excessive centrifugal forces and insufficient lubrication.
2.4 Volumetric Efficiency
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. Mechanical Specifications
3.1 Pump Body
Material: The pump body is usually made of high - strength aluminum alloy. Aluminum alloy offers advantages such as light weight, good heat dissipation, and corrosion resistance. The material is processed through precision casting or extrusion methods to ensure a high - quality and durable structure.
Dimensions:
The overall dimensions vary depending on the specific model. For example, 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 (e.g., 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.
