Marine Cast Steel Cooling Water Pump

I. Product Overview

The marine cast steel cooling water pump is a core heavy-duty equipment of the ship's power cooling system, specially designed for the high-temperature cooling water circulation and transportation conditions of core power components such as main engines, auxiliary engines and turbochargers of medium and large ships. Its core working principle is that the motor drives the impeller to rotate at high speed, transferring kinetic energy to the cooling water to form stable pressure, realizing the suction, pressure boosting and continuous circulation transportation of cooling water. Relying on the excellent high strength, high pressure resistance, high temperature resistance and impact resistance of cast steel materials, it can accurately adapt to the complex marine working conditions of ships with high salt spray, high humidity, large temperature difference fluctuation and severe vibration, stably transport high-temperature cooling fresh water, and effectively control the working temperature of power components. The product has obtained certifications from mainstream classification societies such as CCS, ABS, BV and LR, and is widely used in 10000-200000 ton-class ocean-going cargo ships, oil tankers, LNG carriers, luxury ro-ro passenger ships and large offshore engineering platforms. It is a core equipment for high-temperature cooling guarantee of the power system of medium and large ships.

III. Core Advantages

High Strength and High Pressure Resistance: High-quality cast steel undergoes quenching and tempering treatment, with high tensile strength and strong structural rigidity. It can withstand 3.0 MPa high-pressure working conditions and bumpy impact during ship navigation, not easy to deform or damage, and suitable for heavy-duty cooling systems of medium and large ships

High Temperature and Corrosion Resistance: Cast steel material has excellent high-temperature resistance, can withstand long-term scouring of 120℃ high-temperature cooling water; After anti-corrosion treatment on the surface, it can effectively resist the erosion of high salt spray and high humidity marine environment, not easy to rust and scale

Efficient and Stable Cooling: The impeller adopts a hydrodynamic optimized design, matched with a precision-machined cast steel pump body flow channel, with no pulsation during operation, constant flow and pressure. It ensures uniform distribution of high-temperature cooling water at each cooling point, quickly takes away heat from core components, and avoids local overheating

IV. Typical Application Scenarios

Main Engine Cooling Circulation of Medium and Large Ships: Transports high-pressure and high-temperature circulating cooling water for core high-temperature components such as main engine cylinder liners, pistons and cylinder heads, quickly dissipates a large amount of heat generated by combustion and operation, and ensures long-term full-load stable operation of the main engine

Cooling of Ship Auxiliary Engines and Turbochargers: Provides high-pressure cooling water flow for auxiliary power equipment such as high-power auxiliary engines and turbochargers, controls the working temperature of the equipment, and avoids performance degradation or damage caused by high temperature

Power System Cooling of LNG Carriers: Adapts to the high-temperature cooling needs of power equipment such as main engines and generators of LNG carriers. The cast steel material is temperature-resistant and impact-resistant, can operate stably in low-temperature marine environments, and ensures the navigation safety of the carrier
