Application of Shanghai Fengshen Fluid Controllers in the Marine Sector
A range of specialized marine fluid controllers from Shanghai Fengshen are widely used in the core systems of various vessels. Designed to meet maritime requirements for vibration resistance, moisture protection, and seawater corrosion resistance, and aligned with IMO standards, they ensure safe navigation and system stability through precise fluid parameter control.
Core products and their applications are as follows:
1. Pressure Controllers
Serving as the core component for pressure monitoring and protection on vessels, Fengshen's high-precision pressure controllers are suitable for air conditioning, refrigeration plants, daily fresh water pumps, and other equipment. Core application scenarios:
• Air Conditioning and Refrigeration Plant Protection: Monitors high and low pressure in refrigeration systems. Automatically cuts compressor power if pressures exceed safe limits, and initiates low-pressure shutdown protection. Suitable for shipboard cold storage and crew accommodation conditions.
• Daily Fresh Water Pump Control: Installed in the fresh water tank piping. Automatically starts/stops the pump based on pressure, preventing frequent cycling to extend equipment lifespan.
2. Differential Pressure Controllers
Applied in shipboard hydraulic and lubricating oil circulation systems for monitoring and protecting against pressure differentials, preventing equipment wear or system failure. The products are vibration-resistant and moisture-proof, with settable differential pressure thresholds, suitable for harsh engine room environments.
3. Flow Switches
Suitable for core systems such as hydraulics, ballast water, and fuel management, responsible for flow monitoring and regulation. Core scenarios:
• Hydraulic Actuator Control: Used for steering gear and windlasses. Monitors hydraulic oil flow; deviations beyond setpoints trigger compensation to ensure control precision.
• Ballast Water and Fuel Management: Regulates ballast water flow to improve efficiency and monitors fuel consumption, aiding in energy efficiency optimization in line with IMO requirements.
• Refrigeration System Integration: Suitable for LNG-powered vessels. Works in conjunction with temperature sensors to regulate flow, achieving efficient cooling.
4. Condensing Pressure Regulating Valves & Temperature/Water Flow Regulating Valves
Both are available in marine-specific versions (suitable for fresh/seawater). Core applications are in shipboard air conditioning and refrigeration systems.
• Condensing Pressure Regulating Valve: Regulates the condensing pressure of refrigeration systems, adapting to ambient temperature changes. Corrosion-resistant to seawater.
• Temperature/Water Flow Regulating Valve: Precisely controls water temperature and flow rate. Suitable for crew accommodations and cold storage, enhancing comfort and efficiency.
5. Solenoid Valves (Including Marine-specific Versions)
Suitable for shipboard fire protection, fluid transfer, and refrigeration systems. They are waterproof, vibration-resistant, and corrosion-resistant, enabling automatic pipeline on/off control. Some models are compatible with seawater, ensuring reliable system integration.
6. Thermostatic Expansion Valves & Liquid Injection Valves
As core components of shipboard refrigeration systems, they regulate refrigerant flow. Suitable for air conditioning, cold storage, and LNG cooling units, they provide precise temperature control and energy savings, adapting to special shipboard conditions like vessel motion.
7. Overall Application Advantages and Scenario Coverage
Fengshen's marine controllers are designed for harsh maritime operating conditions, featuring vibration resistance, water protection, and seawater corrosion resistance. Some models meet classification society certifications. They are widely used in various types of vessels, covering core system functions, and contribute to vessel safety, energy efficiency, and environmental compliance.
