technology explained

In our conversations with customers, we are well aware that they may encounter various problems and confusion when selecting, using, and maintaining screw air compressors. In order to provide better support and assistance to you, we have compiled a complete set of common technical questions and answers, hoping to solve your doubts and provide guidance.

Oil-free scroll air compressor can be widely used in departments that require high purification gas sources such as grain, oil and food, medicine and health, and scientific research institutes, and is more suitable for general power air source use.

Screw air compressor is a common compressed air equipment in industry, the cooling method is one of the key factors to ensure its normal operation. There are two main cooling methods: air cooling and water cooling. These two methods have a series of characteristics and applications, which have a significant impact on the performance and efficiency of air compressors.

Because of the internal pressure of the oil-gas tank, the lubricating oil of the air compressor is directed into the cooler for cooling. The cooled lubricating oil enters the oil filter to filter impurities, and a part of the lubricating oil is sprayed into the main engine through the bottom of the main engine to cool the compressed air. The cooled lubricating oil enters the oil filter to filter impurities, and a part of the lubricating oil is sprayed into the air end through its bottom to cool the compressed air. Another part of lubricating oil enters both ends of the air end to lubricate bearings and transmission gears, etc., and finally all the lubricating oil gathers within the air end and is discharged along with the compressed air.

Two-stage compressor is an air compressor that uses two independent compression stages to produce compressed air. Each stage uses a separate rotor and compression chamber to compress the air, the first stage compresses the air to an intermediate pressure level and the second stage compresses the air to the final desired pressure level.Compared with single-stage air compressors, two-stage air compressors have many advantages which can save time, energy and money.

Oil-injected compressors have a higher oil content, while oil-free compressors have extremely low oil content, typically around 0.01ppm, making them truly oil-free.
