Rotary screw air compressor is an efficient and reliable compression equipment widely used in industrial air supply. Its core working principle is based on two intermeshing screw rotors (often called rotors), which rotate to realize air compression. The specific working process is as follows:
When the screw rotors start to rotate, outside air is drawn in through the air inlet. The air inlet is usually equipped with a filter to ensure that the incoming air is clean, thus protecting the inside of the unit.
Rotor: The screw rotor is the core component of the compressor and consists of two screws that engage with each other. As the rotor rotates, air is gradually compressed in the spiral groove of the rotor.
Oil seals: During the compression process, oil seals act as a seal to prevent air leakage and maintain internal pressure. They ensure effective separation of oil and air, optimizing compression efficiency.
Bearings: The rotation of the screw rotor depends on high-quality bearings that support the rotation of the rotor and reduce friction, thus increasing efficiency and equipment life.
The heat generated during compression causes the air temperature to rise, so screw compressors are usually equipped with a cooling system (e.g. water cooling or air cooling) to keep the equipment within the optimal temperature range. The compressed, high pressure air is discharged through an exhaust port for use by the user.
Modern screw air compressors are equipped with an intelligent control system, which can monitor the operation status in real time and automatically adjust the working parameters to improve energy efficiency and prolong the equipment life.
Screw air compressors have become the first choice for industrial air supply due to their high efficiency, low noise and stability. Through optimized design and advanced control technology, Minnuo’s screw compressors can meet the needs of various industrial applications and ensure efficient and reliable air supply.
The cost of a screw air compressor will depend on several factors, such as the size of the compressor, the brand of accessories and features.
On average, a 37kw screw air compressor price from $1,500 to $5000. Installation and maintenance costs should also be considered. Contact us and we’ll arrange for a professional engineer to estimate the cost of your project at a competitive price!
