The invention provides a pump body assembly and a compressor with the pump body assembly. The pump body assembly comprises a crankshaft part, and the crankshaft part comprises a long shaft part; an annular groove is formed in the long shaft part, a first oil guide groove is formed in the peripheral surface of the long shaft part, and the first oil guide groove is communicated with the annular groove to enable lubricating oil to be guided into the annular groove; the bearing part is provided with a bearing hole, the first segment of the long shaft part is located in the bearing hole, and the annular groove is formed in the first segment; in the running process of the pump body assembly, the lubricating oil enters an annular cavity formed by the annular groove and the hole wall of the bearing hole through the first oil guide groove, the contact area between the lubricating oil and the hole wall of the bearing hole is increased, and the lubricating effect of the crankshaft part and the bearing hole is effectively improved; and due to the arrangement of the annular groove, rigidity of the long shaft part of the crankshaft part is reduced, the running adaptive ability of the improved long shaft part is improved, abrasion of the long shaft part and the bearing part is reduced, the service life of a compressor is prolonged, and the reliability of the compressor is improved.
