Technical details and manufacturing context for Tire Pressure Control System

Definition
The Tire Pressure Control System is a critical component of Pneumatic Tire Rollers that continuously monitors tire pressure and automatically adjusts it to maintain optimal levels for different compaction tasks. This system ensures consistent ground contact pressure, improves compaction efficiency, prevents tire damage from underinflation or overinflation, and enhances operator safety by maintaining proper tire performance characteristics. The system operates within a pressure range of 0–2.5 MPa, with a typical operating pressure of 1.0–1.6 MPa, and maintains pressure accuracy of ±0.05 MPa. It is powered by a 24 V DC supply (with ±10% tolerance) and consumes up to 50 W. The system is designed to operate in temperatures from -40°C to 85°C and has an IP rating of IP54–IP65, providing dust and water resistance. Response time is ≤1 second for fast pressure adjustment. The system weighs ≤15 kg and is constructed from corrosion-resistant materials such as aluminum alloy and stainless steel, with rubber seals and electronic components. The system includes pressure sensors in each tire, a central control unit, pneumatic valves, and an onboard air compressor. Operators can set target pressures for different working conditions via a central control panel. The system is suitable for various compaction tasks, ensuring optimal performance and safety. For specific model applications, verify all parameters and standards with the legal manufacturer or supplier.
Working Principle
The system uses pressure sensors in each tire to monitor real-time pressure. When pressure deviates from preset optimal levels, the control unit activates pneumatic valves to either inflate (from an onboard air compressor) or deflate (through release valves) the tires. The system typically includes a central control panel where operators can set target pressures for different working conditions. The control unit continuously compares measured pressure to the setpoint and adjusts accordingly, ensuring that tire pressure remains within the specified accuracy of ±0.05 MPa. This automatic regulation maintains consistent ground contact pressure, which is essential for uniform compaction. The system's response time of ≤1 second allows rapid adjustments to changing conditions, such as varying soil types or load levels. The pressure range of 0–2.5 MPa covers all operating conditions, while the operating pressure of 1.0–1.6 MPa is typical for standard compaction tasks. The system is designed to operate reliably in extreme temperatures and harsh environments, with an IP rating of IP54–IP65 for dust and water resistance.
