The screw machine motherboard is the "brain" and "nerve center" of the entire unit, responsible for receiving sensor signals, executing control logic, issuing operating instructions, and protecting the safe operation of the equipment.
🧠 core function
Signal processing and logic control: Receive sensor signals such as temperature, pressure, and current, and after processing, issue commands to start and stop the compressor, adjust valves, and control the water pump, allowing the unit to operate stably according to the set logic.
Monitoring and display of operating status: Real time collection of operating parameters and display on the panel for easy viewing of unit status, such as suction/exhaust pressure, oil temperature, current, etc.
Fault protection and alarm: When abnormalities are detected (such as overload, overtemperature, high voltage, short circuit), an alarm is immediately triggered or the power is cut off to prevent equipment damage.
Data collection and closed-loop control: Adjust motor speed, valve opening, etc. through PID and other methods to maintain temperature, pressure, and other parameters within the set range.
Communication and remote monitoring: Communication with expansion boards, human-machine interfaces, or upper computers through interfaces such as RS485, supporting remote monitoring and group control of multiple units.
⚠️ The impact of motherboard malfunction
Common manifestations of motherboard aging or damage include controller failure, black screen, unexplained restart, false alarm faults, etc., which can seriously affect the reliability and safety of the unit. The main causes of motherboard failures are often component aging, oxidation, or installation issues, rather than consumables.
🔧 Replacement and repair suggestions
If the motherboard malfunctions, it needs to be replaced in a timely manner to ensure production continuity. Motherboards of different brands and models (such as Yueke, Hitachi, GEA, etc.) are usually not universal. When replacing them, the specific model should be checked, and it is recommended to contact the original factory or professional repair shop for handling.
