A connecting structure of a housing of a scroll pump and a fixed scroll plate

Abstract

The application relates to the technical field of scroll pumps, in particular to a connecting structure of a shell and a static scroll disc of a scroll pump, which comprises the following: a shell, the axial end of which is provided with a connecting surface; a static scroll disc, which is detachably connected to the connecting surface through a plurality of connecting pieces; a dynamic scroll disc, which is arranged in the interior of the shell and is in mesh with the static scroll disc; and a plurality of adjusting shims, which are used for adjusting the axial gap between the static scroll disc and the dynamic scroll disc; wherein a notch is formed in the adjusting shims, and the notch is used for accommodating and avoiding the connecting pieces during assembly; the notch is used for accommodating and avoiding the connecting pieces during assembly by forming the notch in the adjusting shims, so that when the connecting pieces are in a loosened state, the adjusting shims can be moved out of the notch in the radial direction without completely dismounting the connecting pieces and the static scroll disc, thereby simplifying the operation time of the operator.
