Product details
Working Principle
• Gear Meshing: The RN Series Gear Oil Pump consists of a driving gear and a driven gear. When the driving gear rotates under the power of an electric motor, it drives the driven gear to rotate together.
• Liquid Conveyance: During gear meshing, the space volume on the side where the gears disengage gradually increases, creating a vacuum that draws liquid into the pump. On the side where the gears mesh, the space volume gradually decreases, expelling the liquid and discharging it into the outlet pipeline.
• Stable Flow: Due to the continuous meshing of the gears, the pump can continuously draw in and discharge liquid, with a consistent volume discharged per revolution, ensuring stable flow.
Structural Features
• Compact Design: The RN Series Gear Oil Pump typically adopts a side-plate-free, three-piece structure, which is small in size and light in weight, facilitating easy installation and maintenance.
• High-Strength Materials: Key components such as the pump body and gears are made of high-strength materials, such as high-strength cast iron or aluminum alloy, offering high load-bearing capacity and wear resistance.
• Reliable Sealing: The pump operates on the principle of clearance sealing and can be equipped with mechanical seals or magnetically driven seals to ensure leak-free operation during operation.
Performance Parameters
• Flow Range: The RN Series Gear Oil Pump offers a wide flow range, allowing for the selection of an appropriate flow rate based on specific model requirements and application needs.
• Pressure Range: It typically operates at high working pressures, capable of meeting the demands of various hydraulic systems. For example, some models can achieve a maximum working pressure of 25 MPa or even higher.
• Speed Range: The pump has a moderate speed range, typically adjustable between several hundred to several thousand revolutions per minute, to adapt to different working conditions.
• Efficiency Indicators: It boasts high volumetric and mechanical efficiencies, with volumetric efficiencies often exceeding 90%.
Application Fields
• Machine Tool Hydraulic Systems: Serves as a hydraulic power and lubrication oil source pump for machine tools, providing stable flow and pressure.
• Textile Machinery: Used in the lubrication and hydraulic systems of textile machinery to ensure normal operation.
• Construction Machinery: Functions as a power unit in the hydraulic systems of excavators, loaders, and other construction machinery.
• Other Fields: It is also widely applied in hydraulic systems across industries such as metallurgy, mining, shipbuilding, and power generation.
Selection Considerations
• Flow and Pressure Requirements: Determine the required flow and pressure ranges based on specific application scenarios and select an appropriate pump model.
• Medium Characteristics: Consider the viscosity, temperature, corrosiveness, and other properties of the conveyed liquid to choose suitable pump body and sealing materials.
• Installation and Maintenance: Take into account factors such as installation space and maintenance convenience to select a compact and easy-to-maintain pump model.
• Brand and Quality: Opt for well-known brands and pumps with a good reputation for quality to ensure device reliability and stability.
