The primary function of the front bumper is actually to protect pedestrians, as pedestrians are a vulnerable group. Plastic bumpers can alleviate the impact force on pedestrians' legs, especially on the calves, and with the reasonable design of the front bumper, reduce the degree of injury to pedestrians when hit. The second is to reduce the component damage caused by vehicle collisions.

**Working Principle**
In a closed-loop system, a pressure-stabilizing expander is essential to maintain stable system pressure. When the system pressure drops, the water chamber pressure in the connected tank decreases, causing the gas chamber to expand and reduce pressure. This triggers the water pump to automatically refill the system until the pressure reaches the lower limit set by the control system, at which point it stops. When the water is heated, its volume expands, increasing the gas chamber pressure and raising the system pressure. The excess water then flows into the expander (or softening tank) via a safety pressure relief device until the pressure returns to the set limit. Once the pressure stabilizes, the relief stops.
**Scope of Application**
1. Continuous high-temperature water heating systems
2. Industrial and civilian hot water station heating systems
3. Hot and high-temperature water circulation systems
4. Fan coil unit hot and cold water systems
**Performance Characteristics**
This compact pressure-stabilizing expander is designed for efficient performance. It allows separate adjustment of the expansion and gas pressure stabilization parts, enabling up to 90% of the system’s expansion capacity to be stored in the isolated expander. This reduces the overall size and height of the unit by up to 50–60%, saving valuable space and installation costs. Additionally, it features an advanced automatic control system with dual pumps that can operate alternately or simultaneously. It also includes low-water level protection and anti-pressure fluctuation functions, ensuring safe and stable operation.
