The electrical control system serves as the core control hub guaranteeing the stable and precise operation of cryogenic liquid pumps and the entire auxiliary system. Custom-developed specifically for ultra-low temperature operating conditions, this system seamlessly adapts to the transportation needs of cryogenic media such as LNG and liquid nitrogen. It achieves full-process precise control over cryogenic liquid pumps, including start-stop control, speed regulation, and closed-loop pressure control, while coordinating the collaborative operation of auxiliary systems (e.g., temperature, pressure, and flow control modules) to build a highly efficient and interconnected control architecture.
Integrating high-precision sensors and an intelligent PLC control unit, the system enables real-time collection of operating parameters (speed, pressure, temperature, vibration, etc.) of cryogenic liquid pumps and status data of auxiliary systems. Through intelligent algorithms, it realizes dynamic parameter optimization and fault early warning. Equipped with multiple safety protection modules, including overload protection, overpressure interlock, low-temperature shielding, and explosion-proof isolation, the system immediately triggers shutdown or interlock protection upon detecting abnormal operating conditions, eliminating operational risks at the source.
Its user-friendly human-machine interface (HMI) supports both local manual operation and remote intelligent monitoring modes, facilitating operation and maintenance personnel to real-time monitor system status, adjust parameters, and conduct fault diagnosis and troubleshooting. With its stable adaptability, precise control performance, and comprehensive safety guarantees, this electrical control system provides solid electrical control support for the efficient and safe operation of cryogenic liquid transportation systems. It is widely applied in supporting scenarios of cryogenic liquid pumps across energy, chemical, cold chain, and other industries.
