With the advancement of technology and product upgrades, the national standards for grading and testing the physical properties of building exterior doors and windows, including air tightness, water tightness, and wind pressure resistance, have also been upgraded. The current standard GB/T7106-2008 was issued in 2008, and GB/T7106-2019 was released on December 20, 2019 and will be implemented on November 1, 2020. This standard has increased the wind pressure resistance of doors and windows to 7000Pa; significant modifications have been made to the airtightness testing method, including the addition of a airtightness testing buckle box, which determines the airtightness of the test piece by detecting the amount of air leaked through the airtightness buckle box. These requirements have raised higher demands on the physical performance testing equipment for doors and windows, and their structures have also undergone corresponding changes.

The MJ3-C5 series building exterior window comprehensive physical performance testing machine produced by our company fully meets the requirements of various technical indicators of the upcoming national standard GB/T7106-2019.

lMain functions

The physical performance testing machine for building exterior windows produced by our company fully meets the technical requirements of the national standard GB/T7106-2019. Once the specimen is clamped, it can be sequentially tested for three physical properties: air tightness, water tightness, and wind pressure resistance; The airtight detection adopts a specially designed buckle box for measurement, and the sealing between the buckle box and the static pressure box adopts high-pressure pneumatic sealing, which can effectively prevent measurement errors caused by gas leakage. The machine adopts computer control technology, selects variable frequency speed regulating fans and high-power constant torque frequency converters. The equipment operates with low noise, no vibration, and can save more than 40% of electricity, meeting the requirements of environmental protection and energy conservation. The average noise level of the equipment used is not greater than 40 decibels. The console is a luxurious steel wood structure, beautiful and generous, sturdy and durable. Adopting capacitive pressure sensors and high-precision displacement sensors, all important control components (including relays and limit switches, which are imported products) have high control accuracy, stable performance, reliable quality, long service life, and can basically achieve long-term maintenance free operation of the equipment.

The static pressure box adopts a stainless steel structure, and the side plates and vertical displacement plates are made of aluminum profiles, ensuring no risk of rust, deformation, or cracking. The specimen clamping method adopts a patented four-bar linkage fixture, which improves the efficiency of specimen clamping by more than ten times and greatly reduces the labor intensity of the testing personnel. The invisible spray system is integrated with the motherboard, and the hidden nozzles arranged in a matrix can achieve single channel control, which is convenient to use and has no restrictions on specimen specifications.
