Disquisition of Performance Testing Equipment for Vacuum Booster


Article Preview

Focusing on the present situation that the domestic research of vacuum booster performance testing is still at the starting stage, combined with vacuum booster performance testing requirements, a vacuum booster performance testing equipment based on VC++ was designed and realized. It consists of two independent modules, including pneumatic control module and software module. Motion control card was used to control load deflection by pulse output. Dates of displacement sensor, force sensor and pressure sensor were real-timely collected by high-speed data acquistion card. After the analysis of industrial control computer, the vacuum booster input-output characteristic, vacuum leak-proofness are contained. Experimental data shows that the equipment can accurately and truly detect the performance of the vacuum booster. Displacement accuracy can be achieved 0.1mm, force accuracy can be achieved 1N, pressure accuracy can be achieved 0.1kPa.
