A blade compressor (vanecompressor) also known as a slider, a spiner, a spiner or a wheel compressor, is a volume compressor with a simple structure and a low pressure scenario that compresses the gas through the slide of the blade and applies to car air conditioning。
I. Structure
The blade compressor consists mainly of cylinder-shaped cylinders, eccentricly installed rotors, slideable blades within the rotor slots (usually 3-6 blades), front-end caps (sealed into working cavities)。
The key design is that the rotor is different from the cylinder, and the blades are attached to the inner wall of the cylinder by centrifugal or spring-acting force, separating the inner cavity of the cylinder into a closed chamber of multiple variable sizes。
Ii. Rationale
1. Inhalation phase
When the rotor rotates, the blade rotates with the rotor and slides outside, in contact with the wall of the shell, forming multiple seals. The cavity of adjacent blades and gas cylinders is gradually increasing and gases are inhaled from the inhaler。
2. Compression phase
The rotors continue to rotate, and the cavity of the chamber is gradually reduced by changes in the position of the blades, and the gas in the cavity is compressed and pressure is raised。
3. Emission phase
When the chamber volume is reduced to a minimum and the pressure meets the exhaust requirements, the gas is discharged from the vent and a cycle is completed。
4. Continuing work
The rotors continue to rotate and multiple leaves alternately complete the "inhalation-compression-exhaustion" process to provide continuous gas/cool。
Iii. Performance characteristics
1 the structure is simple and compact, operating smoothly and suitable for high-speed operations。
2. High volume efficiency, particularly within low and medium pressure。
3. Low noise, low vibration, suitable for noise-sensitive applications。
4. High lubrication requirements require that oil membranes be sealed between the leaves and the shell。
Iv. Applications
The blade compressor is widely used:
Automobile air conditioning, which is used as a cooler compressor, is small in size and smooth in operation and suitable for deployment in narrow space。
2. Industrial gas, which provides compressed air, applies to automation equipment, gas tools, etc。
Refrigeration systems are more efficient as refrigerant compressors in small refrigeration equipment。
4. Vacuum pumps, which perform vacuum functions through reverse operation, apply to vacuum packaging, laboratory equipment, etc。
Mobile equipment, which is often used for portable air presses, mobile maintenance equipment, etc. Due to tight structures。
Summary
Leaf-form compressors are widely used in the area of low- and medium-pressure gas compression by virtue of their simple structure, smooth operation and adaptive characteristics。
This is particularly true in cases where there are strict requirements for volume, noise and vibration, such as vehicle air conditioning and portable equipment. However, they rely heavily on the lubrication system, and maintenance requires attention to the quality of oil and the wear and tear of leaves。
