Core Product Performance
Basic Regulation: Speed PID closed-loop regulation, unit load control, steam inlet pressure / exhaust pressure cascade regulation, suitable for various load conditions of driven pumps, fans, compressors, etc.;
Start/Stop Logic: Fully automatic program start/stop, manual start/stop mode, can automatically avoid rotor critical speed range to prevent resonance damage to shaft system;
Complete Safety Protection: Over-speed trip, bearing temperature high, lubricating oil pressure low, vibration over-limit, exhaust pressure abnormal and other interlocking shutdown protection, with first occurrence fault memory function;
Redundant Design: Dual-channel speed probe redundant acquisition, single-channel speed measurement failure does not affect the normal operation of the unit;
Event Storage: Massive alarm, trip, operation event records, supports historical data recall and retrieval;
Remote Maintenance: Ethernet access to factory DCS system, can remotely read/write parameters, monitor conditions, diagnose faults;
Hardware Corrosion Resistance: Internal circuit board with three-proof coating, able to withstand oil and moisture industrial harsh environment;
The entire machine can directly be compatible with and replace the old PEAK150 series, cabinet opening and wiring definitions do not need to be modified for renovation and replacement.
Application Domains
HVAC residual heat power generation system for HVAC heating, ventilation, and air conditioning;
Small industrial turbines, expansion machines, speed and load control in chemical and refining plant areas;
Grid-speed regulation and island operation stable pressure regulation for small power steam turbine generators in self-owned power plants;
Overall control of industrial-driven steam turbines for pumps, fans, air compressors;
Measurement and control of steam turbines in hazardous environments of oil and gas stations, explosion-proof plant areas.
