The working principle and characteristics of oil-water lubricated air compressors
At present, oil-water lubricated screw air compressors are a new and high-end type of air compressor, which differs greatly from oil-lubricated screw air compressors in terms of working principle and lubrication method. Below is a detailed introduction to the working principle and advantages of oil-water lubricated screw air compressors.
Working principle of oil-water lubricated screw air compressor
Basic principle: A cylindrical screw and two symmetrically configured planar star wheels form a meshing pair. Usually, there are six grooves on the screw, and each star gear tooth divides the groove it meshes with into two spaces: upper and lower. Implement the working process of each compressor. Due to its two star gear teeth, a single screw compressor is equivalent to a six cylinder double acting piston compressor, operating efficiently. Due to the symmetrical arrangement of cylindrical screws and star wheels, their axial and radial forces can cancel each other out, giving them good balance. This is the reason why oil-free air compressors can operate normally for a long time and have minimal noise.
Characteristics and advantages of oil-water lubricated screw air compressors
1. Reasonable structure with ideal force balance
The oil-free water lubricated screw air compressor is equipped with a star wheel body on both sides of the screw, symmetrically arranged, so that the oil-free air compressor not only has no unbalanced inertia force, but also the axial and radial forces used on the screw cancel each other, making it have ideal force balance.
2. High efficiency
The oil-water lubricated screw air compressor theoretically has no clearance volume, a large single unit capacity, and ideal isothermal compression. Due to the good thermal conductivity of water, the lubricating water continuously circulates and injects into the compression chamber, and the temperature is generally maintained at 45 ℃, close to isothermal compression.
3. Oil free
Replacing lubricating oil with water achieves lubrication, cooling, sealing, noise reduction, and other functions, providing high-quality oil-free air without pollution. The discharged water does not require special treatment and meets environmental requirements.
4. Low noise and vibration
The oil-water lubricated screw air compressor has an excellent power balance system, which can effectively control the vibration source and ensure stable operation without special requirements for the foundation, resulting in low operating noise
5. Long lifespan of the host
The symmetry of the structure and the possibility of setting flow holes balance the radial and axial forces generated during the operation of the compressor. Therefore, the rotor bearing load is small and can operate for 50000 hours. The star wheel made of resin material can operate for 20-30000 hours, and the service life of the air compressor is long.
