| Equipment use: | It is mainly used to test the airtightness, watertightness and compressive deformation resistance of building doors and windows. |
| Conform to the standard: | in line with GB/T 7106-2019 "Detection method for airtightness, watertightness and wind pressure resistance of external doors and windows of buildings". |
| Technical Parameters: | 1 Wind pressure resistance: static pressure difference: ≥±5000pa Accuracy: ≤2% Wireless displacement: 0~50mm Displacement: ±0.1mm 2. Air tightness: air flow: 0~300m3/h Accuracy: air flow≤3%; Differential static pressure≤2% 3. Watertight: Stable Pressurization: Spraying Water: 0-2L/(m2*min) Accuracy: 2L/(m2*min) Differential static pressure: ≥700pa Accuracy: ≤2% Fluctuating pressure: water volume: 2~3L/(m2*min) Accuracy: 3L/(m2*min) Period: 2s~6s Cycle: ≥3s Fluctuating pressure: ≤2% Accuracy: 3s~5s 4. Power supply: three-phase five-wire AC380V 15KW Water source requirements: upper and lower water 5. The measurement error of the air flow measurement device is less than 5% of the indicated value. 6. The measurement error of the differential pressure measuring device is less than 2% of the indicated value. 7. The measurement error of the displacement measuring device is less than 2% of the indicated value. Variable volume buckle box significance: 1. Improve the traffic response rate. 2. Improve the accuracy of flow sampling. 3. It makes it possible to test the flow rate of low pressure gradient. Advantages of variable buckle box technology: 1. Effectively reduce the length of the sealing contact gap between the buckle box and the static pressure box, increase the ability of the buckle box to collect permeability, and reduce the leakage probability of the buckle box. 2. The maximum degree ensures the consistency between the contact area of the static pressure box of the specimen and the contact area around the buckle box, and avoids the additional permeability caused by the partial sealing of the non-specimen. 3. The new clamping method highly simulates the construction and installation method of the specimen under actual working conditions, and does not produce stress-type deformation. 4. Full modulus sealed partition, suitable for most market practical application specimens. |
