Problems solved by technology
In this patent publication, although the oil pump vane can improve the oil pump effect, it is difficult to ensure the installation accuracy of the oil pump due to the manufacturing error of the oil suction pipe.
At the same time, based on the structure of the oil pump blade, the oil pump blade is easily deformed during installation
After the deformation, the acceleration channel is blocked, and the pumping force of the pump oil is limited, which affects the lubrication of the compressor. The oil pumping effect of this lubricating oil pump structure is not good, which affects the lubrication of the compressor. For low-speed inverter compressors, there is a safety hazard of oil shortage.

Embodiment Construction
[0032] The specific implementation manner of the present invention will be described in further detail below by describing the best embodiment with reference to the accompanying drawings.
[0033] Such as figure 1 , figure 2 and Figure 4 As shown, this kind of refrigeration compressor oil pump system includes a crankshaft 1 with a lubricating oil passage 9 inside and an oil suction pipe 5 connected to the crankshaft 1. The oil suction pipe 5 is provided with an oil suction port 6, and the oil suction pipe 5 is provided with The oil suction pipe 5 is divided into V-shaped oil pump slices 2 of three pressurized oil passages, and the three pressurized oil passages communicate with the oil suction port 6 and the lubricating oil passage 9 .
[0034] The lubricating oil passage 9 on the crankshaft 1 has a refrigerant exhaust passage 8. When the crankshaft 1 rotates, the lubricating oil and refrigerant are sucked in from the oil suction port 6 of the oil suction pipe 5, and when ...

The invention discloses an oil pumping system of a refrigeration compressor and an oil pumping method thereof. The oil pumping system comprises a crankshaft and an oil suction pipe, wherein a lubricating oil way is formed in the crankshaft, the oil suction pipe is connected to the crankshaft, an oil suction port is formed in the oil suction pipe, V-shaped oil pumping pieces which are used for dividing the oil suction pipe into three pressurizing oil passages are arranged in the oil suction pipe, and the three pressurizing oil passages are communicated with the oil suction port and the lubricating oil way of the crankshaft. According to the oil pumping system, triangular stable support can be realized by the V-shaped oil pumping pieces, so that the structure is stable, the deformation is difficult, the operating reliability of the oil pumping system can be guaranteed, and the compressor is effectively lubricated.
Description
technical field [0001] The invention relates to a compressor lubricating oil pumping technology in mechanical manufacturing, in particular to a refrigeration compressor oil pumping system and an oil pumping method thereof. Background technique [0002] At present, in the refrigerator compressor industry, the compressor lubricating pump oil generally adopts the oil suction pipe pump oil technology, such as on November 25, 2010, the publication number is CN201891577U, and the name is "a closed compressor oil pumping structure" Chinese patent The open literature discloses an oil pump structure, including a rotor, a crankshaft and an oil suction nozzle. The oil suction nozzle is composed of an oil suction pump barrel and an oil pump vane pressed into the pump oil. The oil suction pump barrel is composed of an upper part, a middle part, and a lower part with different diameters. The blades are composed of upper rectangular large blades, lower rectangular small blades and middle t...
