On site measurement and control system for air tightness of building exterior doors and windows

On site water tightness tester for doors and windowsPreface

Welcome to choose the on-site measurement and control system for air and water tightness of building exterior doors and windows. This equipment is developed based on the new standard GB/T7106-2008 "Classification and Testing Method for Wind Load Resistance Performance of Building Exterior Windows" and the national standard for dynamic wind pressure testing of building doors and windows. It is used as a device for dynamic wind pressure performance testing in building door and window laboratories. This device is used to detect the air and water tightness performance of building doors and windows. This device adopts an automatic operation mode, and the processes of pressure control, data acquisition, grading index calculation, and report generation and recording are automatically completed by the computer.

This device has the advantages of simple structure, convenient use, accuracy and reliability, and high performance price ratio, and is suitable for use by local quality supervision and testing departments and curtain wall manufacturers at all levels.

1、 Equipment Overview

1.1 Name and Model

Model: RN-MXSM

1.2 Execution Standards

JG/T 211-2007 "On site testing method for air tightness, water tightness, and wind pressure resistance performance of building exterior windows" GB/T 7106-2019 "Testing method for air tightness, water tightness, and wind pressure resistance performance of building exterior doors and windows"

1.3 The equipment overview is made in accordance with JG/T 211-2007 "On site testing methods for air tightness, water tightness, and wind pressure resistance performance of building exterior windows" and GB/T 7106-2019 "Testing methods for air tightness, water tightness, and wind pressure resistance performance of building exterior doors and windows" standards, and is suitable for testing the water tightness performance of installed building exterior windows. Its detection object itself also includes its installation and connection parts.

Detection Principle

On site, a static pressure box is formed using sealing plates, enclosure structures, and external windows. The air supply system extracts or blows air from the static pressure box to create a positive or negative pressure difference on both sides of the detection object. The pressure difference is measured through a measuring hole in the static pressure box, and an appropriate number of nozzles are arranged on the outside of the external window for water tightness testing.

Water tightness testing is divided into stable pressurization method and fluctuation pressurization method. The engineering inspection in tropical storm and typhoon areas where the project is located should use the wave pressure method; The stable pressure method can be used for grading testing and engineering testing in non tropical storm and typhoon areas where the project is located.
