1. Air Unit
The air unit is the core of the oil-free screw blower and consists of a main shaft, a primary screw, secondary screws, and an air unit housing. The primary and secondary screws mesh and rotate to compress and transport the gas. The air unit housing provides structural support and sealing protection.
2. Motor
The motor is the power source that drives the air unit and is typically a three-phase asynchronous motor. The motor is connected to the air unit via an axial connection, transmitting power to rotate the air unit's screw.
3. Control System
Oil-free screw blowers are typically equipped with a control system to monitor and control the blower's operating status. This control system can implement start/stop control, load regulation, and protection functions to ensure safe and stable operation of the blower.
4. Intake and Exhaust Systems
The air intake system of an oil-free screw blower typically includes an intake filter and an intake valve to filter and condition the air entering the blower. The exhaust system, consisting of an exhaust duct and a muffler, discharges the compressed air.
5. Cooling System
To maintain the blower's normal operating temperature, a cooling system, such as air or water cooling, is typically used. This helps lower the blower's temperature and ensures efficient operation for extended periods of time.
