Investigation on automatic control system of cyclic pressure test for curtain wall

An automatic and manual control system of cyclic pressure test was developed in consideration of request of water penetration test and structural wind pressure resistance test under cyclic pressure. The system is composed of a pressure chamber used for testing curtain wall, a blower, a pressure control drive equipment, an electric equipment of the pressure control, etc. It can make the chamber pressure fluctuate between high and low values and adjust the cyclic period. Also, the system can realize arbitrary switching between automatic control and manual control on fluctuating pressure of the chamber, and it has the advantages of high automation, simple operation, safety and reliability.
