Abstract

High-efficiency and low-noise refrigeration compressor rotor, the rotor includes a male rotor and a female rotor meshingly connected, wherein the middle sections of the male rotor and the female rotor are air pressurized sections, and both ends of the male rotor and the female rotor are coaxial Equipped with a transmission connecting shaft, the air pressurized section includes a central shaft and multiple helical blades fixed on the outer periphery of the central shaft. The direction of the gas end gradually increases; the pitch of the spiral blade gradually decreases from the intake end of the rotor to the exhaust end of the rotor; a cavity is made inside the central shaft and the spiral blade, and the cavity is filled with rubber Shock the inner core. The high-efficiency and low-noise refrigeration compressor rotor can effectively improve the energy efficiency ratio of the refrigerator, increase the exhaust pressure of the refrigerator, increase the surface tension of the rotor with a cavity structure, and absorb vibration energy with a rubber shock-absorbing inner core, thereby reducing The purpose of reducing noise and improving the contact strength between the central shaft and the spiral blade.

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 air compressors: Mainly used in the field of aerodynamics to drive various pneumatic tools. Due to the development of oil and gas separation and gas purification technology, they are also increasingly used in applications that require very high air quality. Such as: food, medicine and cotton spinning and other industries, occupy many of the original oil-free air compressor market. [0003] Most of the existing screw compressors are not suitable for ultra-high pressure occasions. Due to the meshing contact of the screw blades and the air vibration, the vibration noise in the working state is large, and it is limited b...
