The invention relates to a scroll wrap profile of a liquid-injected scroll compressor. Outer profiles of a static scroll wrap and a dynamic scroll wrap are composed of a section of a variable diameter base circle involute, and the inner profiles of the static scroll wrap and the dynamic scroll wrap are composed by smoothly connecting a variable diameter base circle involute at a center part and normal equidistant curves of the variable diameter base circle involute of the outer ring. The scroll wrap refers to a scroll wrap with compression chamber variational meshing clearance and the wall thickness of the scroll wrap changing gradually. The meshing part close to a central air outlet of the compression chamber is provided with the meshing clearance which forms a pressure unloading channel to the air outlet with small clearance internal leakage, so that the problems of surge pressure in the compression chamber or liquid impacting which are produced by incompressible liquid with relatively large spraying volume. The meshing point of a suction cavity formed by the scroll wrap has no meshing clearance, so that the suction cavity is completely isolated from the compression chamber; at the same time, the wall thickness of the scroll wrap changes thinner gradually from the center to the outer ring, so that the central part of the scroll wrap has enough strength; and the wall thickness at the outer ring of the scroll wrap is relatively thin, so that area utilization rate of a scroll plate is effectively increased.
