How does an oil free scroll compressor work? Unlike dry screw compressors, oil free scroll compressors utilize a new technological path to provide users with an efficient, clean and quiet air supply solution. Next, let's take a closer look at how the oil free scroll compressor works and how it achieves a stable and reliable compressed air supply.
I. Core Structure: Precision Matching of Dynamic and Static Scroll Disks
The core components of the oil free scroll compressor are a pair of nested scroll disks, including a fixed static scroll disk and a dynamic scroll disk that does eccentric rotary translation. The static scroll disk is fixed in the compressor casing, and the dynamic scroll disk is driven by the eccentric shaft to make a rotational movement around the static scroll disk, and the scroll teeth of the two engage with each other to form a series of closed crescent-shaped compression chambers. This unique structural design, eliminating the complexity of the traditional compressor piston, connecting rod and other components, greatly reducing the mechanical friction, reducing the wear and tear of the equipment and the probability of failure.
Second, the intake process: atmospheric pressure driven gas filling
When the oil free scroll compressor start, in the static and dynamic scroll disk on the outermost side of the chamber volume is at its maximum state, at this time the chamber and the inlet connected. Under the influence of atmospheric pressure, outside air rapidly fills these chambers, completing the air intake process. Since there is no lubricant involved inside the oil free scroll compressor, it ensures that the incoming air remains pure and free from oil contamination from the intake stage, which is crucial for industries with extremely high air quality requirements, such as food, medicine and electronics.
Third, the compression process: chamber volume changes to achieve efficient compression
As the dynamic scroll disk continues to do eccentric rotary flat, the dynamic and static scroll disk mesh between the position of the constant change, the air enclosed in the crescent-shaped chamber gradually moved to the center of the chamber, the chamber volume is also constantly reduced. In this process, the air is gradually compressed, the pressure continues to rise. As the engagement of the scroll teeth is continuous and uniform, the compression process is smooth and pulsation-free, compared with traditional equipment such as piston compressors, the oil free scroll compressor can output more stable compressed air. At the same time, its high compression efficiency and low energy consumption help enterprises to reduce operating costs.
Exhaust process: the center chamber discharges high-pressure pure gas
When the air is compressed to the set pressure, the smallest chamber located in the center of the static and dynamic scroll disk is connected to the exhaust port, and the high-pressure pure compressed air is discharged into the subsequent storage tanks or gas systems. During the exhausting process, due to the structural design of the compressor, the operation noise is extremely low, usually controlled at about 60 - 70 dB, almost no noise interference to the working environment, creating a quiet and comfortable working space for employees.
V. Unique Advantages and Applications of Oil Free Scroll Compressor
oil free scroll compressor is widely used in many fields due to its oil free design, low noise, high efficiency, low vibration and other significant advantages. In the food processing industry, it can be directly used in food packaging, mixing and other links to ensure that the food is not contaminated by oil; in the medical field, it provides clean and stable air source for respiratory machines, dental equipment, etc.; in the laboratory, it meets the demand of high-quality compressed air for precision instruments. Its stable and reliable performance provides a strong guarantee for the production and scientific research activities of various industries.
oil free scroll compressor realizes high efficiency and clean air compression through the clever cooperation of dynamic and static scroll discs, which brings a new air source solution for industrial production.
