The high-efficiency low-noise type refrigeration compressor rotor comprises a male rotor and a female rotor which are connected in a meshed mode, the middle section of the male rotor and the middle section of the female rotor are air pressurizing sections, transmission connecting shafts are coaxially and fixedly installed at the two ends of the male rotor and the two ends of the female rotor, and each air pressurizing section comprises a middle shaft and a plurality of spiral blades fixedly installed on the periphery of the middle shaft. Wherein the middle shaft is a conical shaft, and the sectional area of the middle shaft is gradually increased from the air inlet end of the rotor to the air outlet end of the rotor; the screw pitch of the spiral blade is gradually reduced from the air inlet end of the rotor to the air outlet end of the rotor; cavities are formed in the middle shaft and the spiral blades, and rubber damping inner cores are filled in the cavities. According to the high-efficiency low-noise type refrigeration compressor rotor, the energy efficiency ratio of a refrigerating machine can be effectively increased, the exhaust pressure of the refrigerating machine is increased, the surface tension of the rotor is improved through the cavity structure, vibration energy is absorbed through the rubber damping inner core, and then the purposes of reducing noise and improving the contact strength of the middle shaft and the spiral blades are achieved.
Description
technical field [0001] The invention relates to the technical field of refrigeration equipment, in particular to a high-efficiency and low-noise refrigeration compressor rotor. Background technique [0002] Screw compressors are also called screw compressors, including screw air compressors and screw process compressors (vinyl chloride compressors, etc.), screw compressors are volumetric twin-screw oil-injected compressors, and are generally box-type skid-mounted structures. Screw air compressor: It is mainly used in the field of aerodynamics to drive various pneumatic tools. Due to the development of oil-gas separation and gas purification technology, it is also increasingly used in applications that require very high air quality. Such as: food, medicine and cotton spinning and other industries occupy many markets that originally belonged to oil-free air compressors. [0003] Most of the existing screw compressors are not suitable for ultra-high pressure occasions. Due to ...
