A negative pressure absorption system of climbing robots was deeply studied. Based on the utilization rate of the negative pressure climbing robot, the impacts of locomotion system on adsorption force's allocation were studied. According to the differences in the utilization rate of adsorption force, a number of locomotion mechanisms and sealing devices were presented and their compositive performances were analyzed. Through the thermo-dynamic analysis of the component, the process of state changes in suction's flow field was described, and the principles of the adsorption system were revealed. In order to illustrate the essence of the adsorption force provided by suction system, the airflow state changes of the system was simulated by CFD. A climbing robot was presented to verify the stability and reliability of the absorption system.
