What's the difference between screw compressor and scroll compressor?
The working principle of scroll air compressorThe main components of the compressor is an involute scroll but the same two shape angle phase relative position are 180 degrees of the volume, the volume is fixed, and the other one is driven by the eccentric shaft, the axis around the fixed scroll axis of revolution around the volume. In the two volume in many places to form a seal cutting line, properly sealed with two volume at the end face, thus forming several crescent shaped air chamber. The two volume between the public at the point of tangency sealing line with bypass volume and vortex revolution along the curve shifting, the shape and size of the crescent shaped cavity has been changed. The suction port of the compressor is arranged on the upper part of the outer shell of the fixed coil body. When the eccentric shaft rotates clockwise, the gas from the suction port into the suction chamber, have been consumed to the periphery of the suction chamber communicated with the air cavity in the crescent. With the closure of these peripheral crescent air cavity not communicated with the suction chamber, the volume will gradually be closed to the fixed volume transfer center and shrinking, and the pressure is continuously compressed gas.
The scroll air compressor, which is a displacement type rotating machinery, uses the scroll rotor to mesh with the scroll stator to form a plurality of compression chambers. With the translation and rotation of the scroll rotor, the volume of the compressed chambers changes constantly, and the suction and compression of the gas are realized
Screw air compressor, scroll compressor belongs to the rotary displacement type machinery, the main difference: first, design compression principle is different; two, the product used in different working conditions.
