Technical Advantages and Features
(1) Anti pollution and reliability design
The gear adopts 20CrMnTi carburizing and quenching (hardness HRC58-62), and the tooth surface is ground (roughness Ra ≤ 0.8 μ m), which can withstand the impact of 15 μ m particles in oil and has a service life of ≥ 5000 hours (2.5 years can be used after 8 hours per day).
Axial clearance automatic compensation structure (such as floating shaft sleeve), with a clearance recovery accuracy of ≤ 0.02 mm after wear, maintaining a volumetric efficiency of ≥ 80% (traditional design attenuates to 70%).
(2) Low cost and easy maintenance
The number of structural components is 40% less than that of plunger pumps, reducing manufacturing costs by 30%, and is suitable for economical hydraulic systems (such as agricultural machinery and small hydraulic stations).
Modular design enables gear, bearing, and seal replacement time to be ≤ 30 minutes, with maintenance costs 50% lower than plunger pumps.
(3) Wide working condition adaptability
Temperature resistance range -20 ℃~+80 ℃ (with mineral hydraulic oil), -40 ℃~+120 ℃ (with synthetic hydraulic oil).
Allow short time rotation (≤ 10 seconds), and the impact of changes in oil viscosity on flow rate is ≤± 8% (± 15% for plunger pumps).
(4) Low speed and high torque characteristics
The cycloidal gear pump can still maintain 70% of its rated flow rate at a low speed of 500 r/min, suitable for low-speed scenarios such as lubrication systems and delivery pumps.
The flow pulsation of the internal gear pump is ≤± 5%, which can replace some blade pumps and be used in working conditions with moderate stability requirements (such as injection molding machine mold closing auxiliary oil circuit).
