Oil-injected screw air compressors are essential equipment widely used in industry. Their high efficiency and stable performance are due to their unique structural design. The following details the core structural components of oil-injected screw air compressors.
1. Screw Rotor
The screw rotor is the core component of an oil-injected screw air compressor and typically consists of a pair of intermeshing screws. As these screws rotate, they draw in and compress air, ultimately discharging high-pressure air. The design and material selection of the screws are crucial to the compressor's performance and lifespan.
2. Housing
The housing is a key component that protects and supports the screw rotors, while also providing sealing and sound insulation. The housing is typically made of high-strength materials to withstand the high pressure and high temperature environment within. Furthermore, the housing is designed with air inlets, exhaust ports, and oil ports to meet the compressor's operating requirements.
3. Oil Injection System
The oil injection system is a crucial component of an oil-injected screw air compressor, primarily responsible for supplying lubricating oil to the screw rotors to reduce wear and lower temperatures. The oil injection system typically consists of an oil pump, oil filter, oil cooler, and oil nozzles, ensuring that lubricating oil is evenly and stably sprayed onto the screw rotor.
4. Control System
The control system is key to ensuring the stable operation of an oil-injected screw air compressor. It monitors and controls various compressor parameters, such as pressure, temperature, and oil level. If an abnormality occurs, the control system promptly issues an alarm and initiates appropriate protective measures to prevent equipment damage.
