The circulation fan plays a vital role in maintaining uniform temperature and humidity distribution within the HAST Chamber. Wewon’s HAST Chamber features a proprietary circulation fan design that ensures efficient air movement across the test specimens. The patent-approved circulation fan incorporates cutting-edge technology and engineering expertise to provide accurate and reliable testing conditions. Patent: Circulation Fan of HAST Chamber: Patent Authorization Announcement Number: CN213392799U
The innovative fan design optimizes airflows, minimizes temperature gradients, and enhances the chamber’s overall performance. With this patented circulation fan, Wewon’s HAST Chamber offers precise control and uniformity of temperature and humidity, enabling accelerated testing without compromising accuracy.
The sealing integrity of the HAST Chamber is critical to prevent any external influences on the test environment. Wewon’s HAST Chamber boasts a state-of-the-art sealed door design, patented to safeguard the testing process and maintain consistent test conditions. Patent: Sealed Door of HAST Chamber: Patent Authorization Announcement Number: CN213986127U
The sealed door effectively isolates the chamber’s interior from external fluctuations, ensuring that temperature, humidity, and pressure remain constant throughout the testing period. This patent-approved innovation guarantees reliable and repeatable test results by eliminating any unwanted external factors that may impact the specimens during the highly accelerated stress testing.

Summary Description: The utility model relates to the technical field of test chambers.
Specifically, a sealed door of an unsaturated high-pressure steam aging test chamber with good sealing properties is disclosed.
It includes a door panel and a transmission shaft installed in the middle of the door panel and driven by a motor.
A connecting rod turntable threaded with the transmission shaft, and a plurality of connecting rods with one end against the outer peripheral surface of the connecting rod turntable and the other end facing the outside of the door panel,
When the transmission shaft is driven by the motor to rotate, the connecting rod turntable moves back and forth along the thickness direction of the door panel, and drives the ends of each connecting rod to press against or release the inner wall of the test chamber to open or close the sealed door.
Link guide codes are evenly arranged around the outer circumference of the door panel.
This practical setting controls the connecting rod to expand and contract toward the periphery of the door panel according to the change in the steering of the connecting rod turntable.
According to the different directions of extension and contraction of the connecting rod, it is easier for the connecting rod to tilt up and get stuck on the inner wall of the test chamber when it extends, and the sealing door is sealed to the test chamber, and the seal is more secure.
