Compressor‘s “HEART”, Small Miniature Bearings Drive the Entire Air Conditioning Work
Miniature bearings are now a very, very important component in mechanical equipment, and its main function is to support the mechanical rotating body, reducing the compressor in the movement of the whole movement of the friction coefficient, but also to ensure that it returns the accuracy.
Now people’s living standards and conditions are also gradually raised, people living environment improvement and some small commercial and cultural places for the demand for air conditioning is also gradually increased, large-scale inverter air conditioner and dual-cylinder compressor air conditioning The application of the market is more and more broad. The key point in the air conditioner compressor is the use of bearings, which is at the heart of the entire compressor, the importance of micro-bearings on the compressor is like the role of the heart on the human body, and now the air conditioning compressor are used low Vibration, long life of a miniature roller bearings, and the development of such bearings are very strict requirements, so it is important in the air conditioning is self-evident.
And the compressor for the air conditioning is the core of the entire air conditioning, there is no compressor, then there is no so-called air conditioning, and the compressor from the suction pipe inhalation of low temperature and low pressure refrigerant gas, driven by the motor to push the piston to its compression, The high-temperature and high-pressure refrigerant gas is discharged to the exhaust pipe to provide power for the refrigeration cycle so as to be compressed to a refrigeration cycle which is condensed into expansion to evaporation (heat absorption). This shows the status of the compressor.
Compressor control air conditioning, and micro-bearings also constrain the operation of the compressor, the fundamental, a small micro-bearings control the work of the entire air-conditioning, and now match the compressor micro-bearing technical requirements are relatively high, the design And the difficulty of processing is also very large, the bearing requirements are very harsh, high oil temperature, 3.0mpa exhaust pressure, continuous operation 1000h is the life requirements of micro-bearings; open 10min / stop 3min, reciprocating 3000 times; A request, but also in so many requirements after the bearing but not a little wear and tear, showing the compressor on the high demand for bearings.
