What is a sliding vane compressor What is a sliding vane compressor?

　　1, the sliding vane compressor is a positive displacement rotary compressor. It consists of a rotor (with radial slots inside the rotor and sliding vanes installed in the slots) and a stator (or). The rotor rotates in the stator.

　　2, the rotor is offset in the stator. When the rotor shaft rotates, the sliding vane is close to the stator under the action of centrifugal force.

　　3, there is a certain space between adjacent sliding plates. When rotating, the volume of this space goes from the maximum value (the maximum value at the exit formed by the sliding plate) to the minimum value of the tangent point between the stator and the rotor. vice versa.

　　4, the volume increases with the intake of air, and gradually decreases with the compressor section, until the sliding vane opens the air supply port.

　　What is a screw compressor?

　　1, the screw compressor is a positive displacement rotary compressor composed of two parallel configuration of a pair of helical rotors (screws) that mesh with each other. The two rotors are installed in a stator composed of two longitudinally intersecting cylinders. The rotor rotates in the cylinders with a minimum clearance

　　2, the roller bearing supports the rotor shaft. Normally, one rotor drives the other rotor through the rotor helix to rotate. In some cases, the rotor is driven by a pair of external gears.

　　3, when rotating, the spiral surface exposes an air inlet opening at the end of the stator, and air enters and fills the gap of the spiral surface.

　　4, at the other end, two spiral surfaces mesh with each other, thereby reducing the volume of compressed air until the air outlet is opened.

　　The similarities and differences between screw machine and sliding vane machine

　　 General sliding vane compressors and screw compressors require some other components, such as coolers, separators, pressure regulating valves, check valves, etc.

　　The difference lies in the compressor design adopted by each manufacturer based on technical, economic and aesthetic factors. These comparisons are limited to the comparison of the sliding vane type and the screw as the main engine-the core of the compressor.

　　 volume effect

　　The relationship between effective air displacement and geometric volume is volumetric efficiency. It is inside the rotor-stator unit and is affected by air leakage through the inlet under pressure. These air leaks need to be kept to an absolute minimum, because the energy required to compress the air back into the inlet is a loss. The less internal leakage, the greater the volumetric efficiency, and the reduction in power required to measure the unit air displacement (specific energy).
