The Wheel Hub Airtightness Testing Machine is specially designed for airtightness and leak detection testing of tubeless wheels used in automobiles and motorcycles. The system utilizes a hydraulic clamping mechanism to securely seal both sides of the wheel hub with high-strength sealing gaskets, creating a reliable airtight testing environment.
The machine employs the air-pressure bubble immersion method, one of the most widely accepted and effective techniques for detecting air leakage in wheel assemblies. During testing, compressed air is introduced into the sealed wheel cavity, and the wheel is submerged in water. Any leakage points are immediately visible through escaping air bubbles, enabling fast and accurate inspection.
This equipment is ideal for wheel manufacturers, automotive suppliers, quality control departments, and testing laboratories seeking to ensure product safety, sealing performance, and manufacturing consistency.
