Technical principle and system architecture of dual-motor pneumatic control box
Core functional module
Dual-motor independent control: Adopting a dual-channel PID algorithm, it supports motor start-stop, speed adjustment, and fault interlocking, enabling automatic switching or synchronous operation between one in use and one as a backup.
Pneumatic integrated unit: Integrates solenoid valve group (such as GT series aluminum alloy double piston actuator), pressure sensor and flow regulating valve to precisely control the cylinder stroke and pneumatic valve opening.
Intelligent monitoring system: Through PLC and touch screen interaction, it can display real-time parameters such as motor load and gas pressure, and supports Modbus protocol for integration into industrial IoT.
Typical application scenarios
Dual-pump redundancy system: In the delivery of lithium battery electrolyte, the standby pump automatically starts within 0.5 seconds when the main pump fails, ensuring the continuity of the production line.
Synchronous motion control: In the automobile welding production line, the dual-motor driven robotic arm and pneumatic gripper work together with a positioning accuracy of ±0.1mm.
Technical advantages
High reliability: The box body is made of 304 stainless steel with a sealed design and a protection level of IP65, suitable for harsh environments ranging from -20°C to 60°C.
Energy-saving and high efficiency: Equipped with a pneumatic energy recovery device, the utilization rate of compressed air is increased by 30%, and the annual energy consumption is reduced by about 15%.
Industry application cases
After adopting this control box, a photovoltaic cell manufacturer saw a 42% reduction in the failure rate of their dual-motor driven silicon wafer sorting machine and an 18% increase in production capacity, validating its value in the field of precision manufacturing.
