Problems solved by technology

Since the oil supply height of the crankshaft centrifugal pump oil section has a square relationship with the crankshaft diameter, it is greatly affected by the crankshaft diameter. After the crankshaft shaft diameter is thinned to a certain extent, the oil supply capacity will be greatly reduced, which will affect the normal operation of the refrigeration compressor.

Embodiment

[0063] Refer below Figure 1-Figure 5 A compressor 100 according to a specific embodiment of the present application is described.

[0064] Such as figure 1 As mentioned above, the compressor 100 of this embodiment includes an oil supply structure 1 , a frame 2 , a stator 3 , a rotor 4 and a casing 5 .

[0065] The oil supply structure 1 includes a crankshaft 11 and an oil pump part 12. The crankshaft 11 is arranged vertically. The crankshaft 11 has a central hole 111. The oil pump part 12 fits in the lower part of the central hole 111. Between the outer peripheral wall of the oil pump part 12 and the inner peripheral wall of the central hole 111 There is a gap between them, and the oil pump part 12 can rotate relative to the crankshaft 11. The width of the gap between the outer peripheral wall of the oil pump member 12 and the inner peripheral wall of the central hole 111 is S, and S satisfies the relational formula: 0.04mm≤S≤0.2mm. A spiral oil groove 1211 extending along...

Abstract

The invention discloses an oil supply structure for a compressor and the compressor with the oil supply structure. The oil supply structure for the compressor comprises a crankshaft, wherein the crankshaft is arranged vertically and is provided with a central hole; and an oil pump piece, wherein the oil pump piece is matched at the lower part of the central hole, a gap is reserved between the outer peripheral wall of the oil pump piece and the inner peripheral wall of the central hole, and the oil pump piece can rotate relative to the crankshaft. According to the oil supply structure for the compressor according to the embodiment of the invention, the oil supply amounts of various components of the compressor are increased on the premise of thinning the diameter of the crankshaft; and theefficiency and the reliability of the compressor are improved.

Description

technical field [0001] The invention relates to the field of refrigeration equipment, in particular to an oil supply structure for a compressor and a compressor with the same. Background technique [0002] For reciprocating refrigeration compressors, the oil supply system is mainly responsible for lubricating the moving parts of the compressor, reducing the wear of the parts during operation, and reducing the operating temperature of the compressor, so as to improve the reliability of the compressor and prolong its service life the goal of. [0003] The existing reciprocating refrigeration compressor oil supply system is limited by structural design and processing technology, and generally adopts a centrifugal pump oil structure + a spiral viscous oil pump structure. The oil supply structure includes a crankshaft, an oil pump part, a frame, a stator, a rotor, a casing and an oil pool. The crankshaft is generally provided with a centrifugal pump oil section and a helical vi...
