Door window test system

Abstract

The embodiment of the invention provides a door window test system. The door window test system comprises a door window, an electronic control system, a high voltage variable frequency fan, a back wallboard, a displacement acquisition system and a CPU module, wherein the door window is hoisted on the back wallboard by virtue of a transmission device and forms an airtight cavity with the back wallboard; by virtue of the electronic control system, air pressure output of the high voltage variable frequency fan is controlled, a static air pressure is formed in the airtight cavity, and a test is performed; by virtue of the high voltage variable frequency fan, maximum output power can reach 12kPa, and positive and negative pressure switching is performed, so that performance of the test system is stable; the test system provided by the embodiment of the invention has excellent pressure capacity and electronic control stability and can cope with a large load test on a large-size door window product; multiple door windows can be tested, so that test efficiency is improved; a spraying system can be combined according to the actual situation, so that test convenience is improved; and a testresult is obtained by virtue of the CPU module.

Description

technical field [0001] The invention relates to the technical field of doors and windows, in particular to a door and window testing system. Background technique [0002] With the in-depth development of modern architectural concepts, more and more architectural designs at home and abroad have introduced a large number of door and window opening systems. Therefore, door and window detection based on building codes and engineering requirements will become particularly important; System material production and processing, component assembly, product output areas, and door and window testing have a wide range of requirements. Customers hope to provide a broader basis for performance verification for their product design, sales or purchases. [0003] At present, domestic door and window testing equipment generally adopts a box structure. The wind pressure loading system and the spray system are integrated inside the box. The output power of the fan used is about 6kPa. Pressuriz...

AI Technical Summary

Problems solved by technology

[0004] On the one hand, the box-type structure occupies a large area and cannot be well optimized for space. On the other hand, the frame structure is fixed in a single installation. For samples of different specifications, the adjustment is more complicated, which is limited by the test of large-scale samples. The efficiency is low; secondly, the output power of the fan used is only in the range of about 6kPa, which is difficult to meet the wind pressure test of 8kPa or even more than 10kPa proposed by more and more customers
