Problems solved by technology

[0002] Rotary compressor refrigeration and heating are performed in a closed system, such as compression, but during operation, it is easy to generate radiation noise, suction and exhaust port noise, suction and exhaust pipe vibration, base vibration, suction and exhaust pipe vibration and other noise vibration series Among them, gas force and moment, rotor unbalanced inertial force, electromagnetic force and torque pulsation, friction and impact of moving parts and pressure pulsation in the shell are the main sources of compressor vibration, and through the cylinder, bearing, compressor shell And the liquid reservoir transmits vibration to the air conditioning system, which reduces the sound quality of the air conditioner, thereby reducing user satisfaction
[0003] At present, the compression components of compressors are mainly made of gray cast iron with flake graphite. Gray cast iron is a commonly used multi-phase damping alloy, and its internal friction is related to the uneven structure. The softer tissue produces plastic deformation, which greatly improves the energy dissipation of the alloy, and the cost of the material is low, but its damping performance is sensitive to frequency. Only when the vibration frequency reaches the natural vibration frequency of the material can it have better damping performance. And it is only effective at low temperature, the specific damping value S.D.C% is about 6, and the vibration energy generated during the compression movement is reduced very little, which makes the compressor body vibrate more, which in turn affects the quality requirements of the compressor
