Product details
3HA Cycloidal Gear Oil Pump
The3HA Cycloidal Gear Oil Pumpis a positive displacement pump featuring a cycloidal gear configuration with internal and external rotors. Below is a detailed introduction to this pump:
------
I. Working Principle
• Core Structure: Composed of an internal rotor (with an epitrochoidal tooth profile) and an external rotor (with a circular arc tooth profile). The difference in tooth count between the internal and external rotors is one, creating sealed chambers through meshing motion.
• Working Process:
• Oil Suction Stage: As the internal rotor rotates, the volume of the chambers formed with the external rotor increases, creating a partial vacuum that draws in oil.
• Oil Delivery Stage: Continued rotation of the rotors moves the oil trapped between the meshing teeth towards the discharge side, enabling continuous delivery.
------
II. Performance Characteristics
• Compact Structure: Smaller in size compared to conventional gear pumps for the same displacement, making it suitable for space-constrained applications.
• Stable Flow Rate: The cycloidal tooth profile ensures minimal flow pulsation, resulting in smooth operation.
• Low Noise Level: The smooth meshing process significantly reduces noise compared to standard gear pumps.
• Strong Self-Priming Capability: Capable of operating under low inlet pressure conditions.
• High Resistance to Contamination: The relatively large tooth clearances make it less sensitive to small particles in the oil, suitable for harsh operating conditions.
• Material Optimization: Utilizes high-strength composite materials or surface coating technologies to enhance wear and corrosion resistance.
• Intelligent Control: Incorporates sensors and variable frequency technology for precise flow and pressure regulation.
• Energy Efficiency and Environmental Friendliness: Optimized tooth profiles reduce internal leakage, improve volumetric efficiency, and lower energy consumption.

III. Application Areas
• Hydraulic Systems: Used in hydraulic power units for machine tools, construction machinery, injection molding machines, and other equipment.
• Lubrication Systems: Employed for delivering lubricating oil to engines, gearboxes, bearings, and other components.
• Fuel Delivery: Functions as a fuel pump in automotive, marine, and aviation fuel systems.
• Chemical Industry: Suitable for transferring high-viscosity media or fluids containing small particles.
• Food and Pharmaceutical Industries: Stainless steel or food-grade material versions are available for conveying liquids with stringent hygiene requirements, such as food and pharmaceuticals.
------
IV. Selection and Maintenance Recommendations
• Selection Guidelines:
• Clearly define requirements for flow rate, pressure, and medium viscosity.
• Choose appropriate pump body materials and structural forms based on installation space and operating environment.
• Consider whether intelligent control functions are necessary.
• Maintenance Recommendations:
• Regularly inspect bearings and seals for wear, replacing worn parts promptly.
• Ensure proper lubrication of bearings and drive components to prevent dry friction.
• Prevent contaminants from entering the pump and regularly clean filtration devices.
• Monitor vibration and noise levels, investigating and addressing any abnormalities promptly.
