05. Equipment Composition

• The equipment consists of four core parts: control unit, door/window mounting frame, deformation measurement unit, and repeated opening/closing actuation unit. Each unit works together to ensure efficient and accurate testing.
• Control Unit:As the core control hub, it accurately applies required test loads to the door/window, sends control signals to the repeated opening/closing device for precise action control; simultaneously receives, organizes, and stores deformation signals from the deformation measurement device, ensuring complete and traceable data. The unit utilizes advanced microcomputer control technology with a modular architecture design, offering stable and reliable system operation, strong anti-interference capability, and long-term continuous operation.
• Door/Window Mounting Frame: Mainly used for installing and fixing door/window specimens. It is integrally welded from high-quality section steel, providing high structural strength and stability, effectively preventing specimen shaking or displacement during testing, ensuring accurate test data, and accommodating quick clamping of doors/windows of various sizes.
• Deformation Measurement Unit & Repeated Opening/Closing Actuation Unit: Under the command of the control unit, these units accurately perform repeated opening/closing actions and collect deformation data. Core components use imported cylinders and pneumatic components, offering long service life, stable and durable operation. Equipped with a uniquely designed proprietary mechanism, they can accurately complete complex handle twisting actions, replicating real-world usage scenarios—a technology currently unique in China.
• A two-stage air source filter is configured to effectively filter moisture generated during air pump operation, significantly extending the service life of pneumatic components and reducing equipment maintenance costs.
