HOWO 30L+8 iron air tanks from Sinotruk, designed as dual-chamber air reservoirs, serve the critical function of storing and stabilizing compressed air, supplying power to the vehicle's pneumatic systems (such as braking mechanisms and pneumatic valves). The operational principle can be broken down into the following key stages:

1. Air Storage: The compressed air generated by the vehicle's air compressor is dried to remove moisture and impurities before being directed into two separate chambers—30L and 8L—for storage. The larger 30L chamber, with its greater capacity, primarily supplies a steady air source to components that consume significant amounts of air, such as the service brake and parking brake. Meanwhile, the smaller 8L chamber, designed for components more sensitive to air pressure fluctuations—like pneumatic assist devices and air-control valves—provides air without causing pressure variations that could interfere with the operation of these precision parts when drawing from the larger chamber.

2. Voltage Stabilization Buffer: When air-consuming components (such as stepping on the brake) rapidly draw air, the compressed air stored in the reservoir tank is quickly replenished, preventing a sudden drop in air pressure caused by the compressor's delayed response. The dual-chamber design minimizes air pressure interference between different components—for instance, while the larger chamber supplies air for braking, the smaller chamber maintains stable pressure, ensuring that other starting devices continue to operate smoothly.

3. Air Circuit Diversion and Safety Assurance: The two chambers are connected via separate air pathways (typically featuring independent inlet and outlet ports). Some models are equipped with a pressure sensor or a safety valve: when the internal air pressure exceeds the set threshold (usually 8–10 bar), the safety valve automatically releases excess air to reduce pressure, preventing damage to the air tank caused by overpressure. Meanwhile, the iron outer casing is designed with a certain pressure margin—generally rated to withstand up to 1.5 times the working air pressure—ensuring safe operation during both storage and gas supply processes.
