Marine Copper Gear Pump
I. Product Overview
The marine copper gear pump is a core equipment of the ship's fluid transportation system, specially designed for the transportation of media such as lubricating oil, fuel oil and fresh water. It realizes medium suction and pressure boosting by forming a closed cavity through the meshing of precision copper gears. Relying on the advantages of copper alloy such as corrosion resistance, wear resistance and non-magnetism, it is suitable for complex marine working conditions with high salt spray and high humidity. It is widely used in various ocean-going, coastal and inland river ships, and complies with the SOLAS Convention and classification society certification standards such as CCS, ABS, RS and BV.
II. Core Parameter Range
Parameter Category | Specific Range/Specification | Adaptation Description |
Pressure Range | Rated 0.2-1.2MPa, Maximum 1.6MPa | Meets the pressure requirements for lubrication, oil supply and fresh water transportation |
Flow Range | 5-150m³/h, supporting graded customization | Adapts to different demand volumes of 500-200000 ton-class ships |
Medium Adaptability | Viscosity 5-1500mm²/s, Temperature -20℃~120℃ | Can transport lubricating oil, fuel oil, fresh water, etc. |
Material Specification | Copper gears, steel transmission shaft | Corrosion and wear resistant, non-magnetic, suitable for marine environment |
Operating Performance | Volumetric efficiency ≥93%, Noise ≤70dB(A), Service life ≥10000h | Supports 24-hour continuous and stable operation |
III. Core Advantages
Corrosion and Salt Spray Resistance: Copper alloy material can effectively resist the erosion of high humidity and strong salt spray in the marine environment, and is not easy to rust and scale
Stable Operation: Precision gear meshing without pulsation, constant pressure and flow, suitable for ship vibration working conditions
Non-magnetic and Wide Adaptability: Non-magnetic characteristics can be used in military and scientific research ships without interfering with navigation and detection equipment
Convenient Maintenance: Modular design, wearing parts can be quickly replaced, maintenance cycle ≥6 months
IV. Typical Applications
Circulating transportation of lubricating oil for ship main engine/auxiliary engine
High-pressure lubricating oil supply for gearboxes and stern tubes
Ship fuel oil and fresh water transfer and emergency guarantee
Fluid transportation system of special ships (military/scientific research)
V. Selection and Precautions
1. Selection Basis: Ship tonnage, type of transportation medium, flow and pressure requirements, and navigation working conditions;
2. Maintenance Points: Regularly clean the filter screen, check the seals, and preheat before starting in low-temperature environment;
3. Compliance Requirements: Select products with classification society certification to ensure compliance with ship safety standards.
