Semi-trailer 4-hole air tank It is a critical component of the semi-trailer braking system, primarily used to store compressed air and provide a stable air supply for systems such as braking. Here's a related introduction:
Structure and Specifications: Typically, it features 1 large hole for installing the trailer valve, 2 smaller holes for connecting air lines, and another hole that may be used for draining water or other specific purposes. Materials include aluminum alloy and iron, with common volumes such as 20L and 30L. The diameter usually ranges from about 200mm to 300mm, while the length varies from 400mm to 1000mm depending on the volume. Note that the size of the air tank required can differ based on the specific vehicle model.
- How it works: Compressed air generated by the air compressor is stored in an air reservoir. During braking, the reservoir delivers compressed air through connecting ports to components such as the brake chambers, which then actuate the brake shoes or calipers to initiate the braking process. Meanwhile, as the compressed air remains inside the reservoir, impurities and moisture settle at the bottom, effectively filtering and purifying the air. Additionally, the reservoir helps stabilize air pressure, ensuring the braking system operates smoothly and reliably.
- Function: Primarily, it stores compressed air to supply the semi-trailer's braking system, pneumatic horns, and other components, ensuring these systems operate smoothly. It also filters impurities from the air, reducing wear on the air circuit system's components, while simultaneously stabilizing air pressure—thereby enhancing both the performance and reliability of the braking system.
