Double-cylinder energy-efficient refrigerator and air conditioner compressor

Abstract

The invention discloses a double-cylinder energy-efficient refrigerator and air conditioner compressor. The compressor comprises an oil suction pipe, a crankshaft, a main crankshaft connecting rod, a rack, a main cylinder sleeve, a main piston, an upper bearing plate, a booster oil pump and a main cylinder cover. According to the double-cylinder energy-efficient refrigerator and air conditioner compressor, a piston oil hole and a piston pin oil hole in a traditional piston are omitted; piston lubricating oil is supplied from the booster oil pump on the upper bearing plate; the piston is lubricated through an upper lubricating oil inlet hole formed in the upper portion of the cylinder sleeve, and greasy dirt is discharged through a lower greasy dirt discharge hole formed in the lower portion of the cylinder sleeve; the service life of the cylinder sleeve and the piston is prolonged, and the compression pressure of the piston is improved; as the piston is provided with the oil discharge hole, the compression pressure of the piston is increased, and the efficiency is improved; acting force of two air cylinders has a difference of 180 degrees. One air cylinder presses air, and the other air cylinder introduces the air. The two air cylinders do work mutually. The working efficiency of a motor is improved. The effect of energy conservation is achieved.

Description

technical field [0001] The invention relates to a double-cylinder high-efficiency energy-saving refrigerator air-conditioning compressor, in particular to a double-cylinder high-efficiency energy-saving refrigerator air-conditioning compressor. Background technique [0002] With the improvement of people's living standards, refrigerators have been popularized in most households. The compressor is the heart of the refrigerator. Once the refrigerator is turned on, the compressor will continue to run. The piston and cylinder liner of the traditional refrigerator compressor are shown in the figure. The lubricating oil in between is sucked upward through the oil suction pipe, the lubricating oil enters the connecting rod oil pipe through the oil hole of the crankshaft connecting rod, the excess oil is discharged through the residual oil hole on the crankshaft, and the lubricating oil enters the piston pin shaft oil hole on the piston pin and then Reaching the piston oil tank, the...

[0002] With the improvement of people's living standards, refrigerators have been popularized in most households. The compressor is the heart of the refrigerator. Once the refrigerator is turned on, the compressor will continue to run. The piston and cylinder liner of the traditional refrigerator compressor are shown in the figure. The lubricating oil in between is sucked upward through the oil suction pipe, the lubricating oil enters the connecting rod oil pipe through the oil hole of the crankshaft connecting rod, the excess oil is discharged through the residual oil hole on the crankshaft, and the lubricating oil enters the piston pin shaft oil hole on the piston pin and then Reaching the piston oil tank, the piston oil tank is provided with a hole connected to the crankshaft connecting rod, so it will cause pressure leakage during compression, resulting in low compression efficiency, and it is easy to suck the oil in the piston oil tank into the cylinder when expanding and sucking Causes oil leakage to be discharged, so that the oil enters the refrigeration system, resulting in a decline in the cooling effect
