1. Model analysis
IPH-4A-32-20: foot-mounted installation (fixed flange hole), displacement 32ml/rev, design code 20.
IPH-4B-32-20: Flange installation (fixed flange at the shaft end), displacement 32ml/rev, design code 20.
2. Core parameters
Pressure performance
Rated pressure: 21MPa (214bar)
Maximum withstand pressure: 30Mpa (306bar)
Pressure adjustment range: 0-30Mpa, suitable for high-pressure hydraulic systems.
Flow characteristics
Displacement: 32ml/rev, the flow range covers 25-40ml/rev, which meets the needs of medium and high flow rates.
Speed range: 300-2000min-1, support low-speed to high-speed operation.
Medium and temperature
Applicable media: mineral oil-based media such as hydraulic oil and lubricating oil, with a viscosity range of 5-500cSt (ISO VG32-68 is recommended).
Working temperature: oil temperature 5-65℃, ambient temperature 0-60℃.
Structure and weight
Structure: The design of the internal meshing gear is higher than that of the external meshing pump.
Weight: About 10.5kg (the specific installation method is slightly different).
3. the technical characteristics
High-efficiency and high-pressure design
It adopts patented axial and radial pressure technology, with a rated pressure of 21MPa and a maximum tolerance of 30Mpa, which is suitable for high-pressure hydraulic systems.
Correct the meshing design of involute short teeth to reduce flow pulsation and low pressure fluctuation.
Low noise operation
The noise of gear meshing is reduced by 70%, and the operating noise is ≤65dB. It is suitable for noise-sensitive scenarios (such as textiles and food processing).
Wear-resistant and long life
The gears and bearings are made of high-strength alloy steel, the surface is hardened, and the wear resistance is excellent.
Axial and radial gap compensation design reduces internal leakage and extends service life.
Structure and maintenance
The structure is compact and the installation method is flexible (foot seat type or flange type).
Modular design, easy replacement of seals, low maintenance costs.
4. the application scenario
Industrial hydraulic system
Hydraulic power sources for injection molding machines, die-casting machines, CNC machine tools and other equipment.
Hydraulic transmission system of construction machinery (such as cranes and excavators).
Lubrication and transportation
Transportation of high-viscosity media (such as lubricants and chemical raw materials).
Lubrication systems for iron and steel metallurgy, papermaking, textile and other industries.
Special working conditions
The yaw and pitch hydraulic system of wind power generation equipment.
Hydraulic drive units for port machinery and lifts.
