Deep Dive: Specialized Components of the CO2 Injection System

The Supercritical CO2 Injection System for the RG90 Production Line is engineered with high-precision sub-components to ensure the stable delivery of physical foaming agents. Below are the detailed specifications for the booster, metering, and safety modules:

1. Pressure Boosting and Metering Modules
The system utilizes a two-stage approach to handle CO2 fluid, ensuring it reaches the required supercritical state for injection.
Auxiliary Booster Machine:
Rated Working Pressure: 10 MPa.
Control: Pressure adjustment is managed via a digital display electronic pressure gauge.
Metering Injection Pump:
Rated Working Pressure: 10–20 MPa.
Power System: Equipped with a 0.55 kW motor and a 0.55 kW variable frequency drive (VFD) for precise flow regulation.
Alert System: Integrated pressure alarm with a digital electronic display.
2. Fluid Storage and Thermal Management
Liquid Storage Tank: Designed for high-pressure stability with a maximum safety pressure of 16 MPa.
Cooling Circulation Pump: A dedicated set to maintain the CO2 in the required liquid or supercritical phase before injection.
3. Intelligent Control and Monitoring System
The system features an integrated suite for real-time data visualization and automated regulation:
Pressure Control:
The storage tank is monitored and regulated by dedicated pressure sensors.
All values are displayed on high-precision digital pressure instruments.
Temperature Control: Managed via intelligent electronic meters with digital displays for constant monitoring.
Flow Monitoring:
Includes a specialized CO2 Intelligent Flow Meter with an electronic digital display.
Pressure Rating: The monitoring hardware is rated for up to 32 MPa to ensure a high safety margin.
4. Comprehensive Safety Protections
To ensure operator safety and equipment longevity, the system includes multiple fail-safes:
Mechanical Safety: A full set of safety valves to prevent overpressure.
Operational Alerts: A CO2 cylinder under-pressure alarm to notify operators when the gas source is low.
Electrical Safety: A complete leakage protection system to prevent electrical hazards.
