	Funding: National Natural Science Foundation of China (Project No. 11305227) A new large scale accelerator facility is being designed by Institute of Modern Physics (IMP) Lanzhou, which is named as the High Intensity heavy-ion Accelerator Facility (HIAF). This project consists of ion sources, Linac accelerator, synchrotrons (BRing) and several experimental terminals. During the operation of Bring, the heavy ion beams will be easily lost at the vacuum chamber along the BRing when it is used to accumulate intermediate charge state particles. The vacuum pressure bump due to the ion-induced desorption in turn leads to an increase in beam loss rate. In order to accumulate the beams to higher intensity to fulfill the requirements of physics experiments and for better understanding of the dynamic vacuum pressure caused by the beam loss, a dynamic vacuum pressure simulation program has been developed. Vacuum pressure profiles are calculated and compared with the measured data based on the current synchrotron (CSRm). Then the static vacuum pressure profiles of the BRing and one type of pump which will be used in the BRing are introduced in this paper.
