Abstract

The invention provides a pump body assembly, a compressor and heat-exchange equipment. The pump body assembly comprises a crankshaft and a first flange, wherein the crankshaft is provided with an eccentric structure; the first flange is arranged on the crankshaft in a sleeving manner; an oil guiding groove is formed in the first flange and / or the crankshaft and is positioned in the overlapped part of the first flange and the crankshaft; one end, far away from the eccentric structure, of the oil guiding groove, is a first oil guiding end; one end, far away from the eccentric structure, of the first flange, is a first flange end; the distance from the first oil guiding end of the oil guiding groove to the eccentric structure is smaller than that from the first flange end of the first flange to the eccentric structure. As the end face of the first oil guiding end of the oil guiding groove with the structure and the first flange end of the first flange are arranged at an interval or are not communicated with each other, influence of air pressure in the cavity of the compressor on refrigerant oil in the oil guiding groove is reduced, and the refrigerant oil is prevented from rapidly flowing in the oil guiding groove; therefore, flow rate of the refrigerant oil in the oil guiding groove is easy to control, and the lubricating performance of the pump body assembly is ensured.

Description

technical field [0001] The invention relates to the technical field of heat exchange, in particular to a pump body assembly, a compressor and heat exchange equipment. Background technique [0002] Compressors, especially rolling rotor compressors, generally use the upper flange as the main bearing of the pump body assembly to fix and support the crankshaft to prevent the crankshaft from swinging. [0003] Usually, the gap between the existing crankshaft and the upper flange is 0.01 to 0.03 mm. When the gap between the two is too large, the swing of the crankshaft is large, and the gap is too small. Due to the limitation of the processing level of the parts, when the parts have poor precision It may cause the upper flange and crankshaft to be stuck. [0004] like figure 1 As shown, the upper flange 10' is provided with a through oil guide groove 11', and the refrigerated oil flows through the oil guide groove 11' to lubricate the mating surface of the upper flange 10' and t...
