1. Main Unit (Compressor Main Unit)
The main unit is the core component of the screw air compressor, responsible for compressing the air into high-pressure gas. The main unit contains screws composed of a pair of male and female rotors that mesh together during operation to compress the air to the desired pressure. The precision and material of these screws directly affect the efficiency and lifespan of the compressor.
2. Electric Motor
The electric motor provides power to the screw air compressor, transmitting this power to the main unit through a drive system. Screw air compressors typically use high-efficiency, energy-saving electric motors to ensure stable operation and reduce energy consumption. The size of the motor’s power directly determines the compressor's output capacity.
3. Intake Valve
The intake valve controls the amount of air entering the main unit and adjusts the intake volume as needed to maintain stable output pressure. During compressor startup and shutdown, the intake valve automatically opens or closes to manage the air effectively and prevent wastage.
4. Oil Separator
During the compression process in a screw air compressor, lubricating oil mixes with the compressed air. The oil separator's role is to remove the lubricating oil from the compressed air to ensure the output air is clean and dry. The filter inside the separator needs to be regularly replaced to maintain separation effectiveness and ensure normal operation of the equipment.
5. Lubrication System
The lubrication system provides lubricating oil to the main unit and other mechanical parts to reduce friction and wear, extending the equipment's service life. Lubricating oil not only serves as a lubricant but also provides sealing, cooling, and noise reduction. The lubrication system typically includes an oil pump, oil cooler, and oil filter.
6. Cooling System
The cooling system is crucial for ensuring the long-term stable operation of the screw air compressor. As the compression process generates a large amount of heat, the cooling system dissipates this heat generated during operation to prevent overheating and potential damage. Common cooling methods include air cooling and water cooling.
7. Control System
Modern screw air compressors are usually equipped with advanced control systems to monitor and adjust various parameters such as pressure, temperature, and operating status. The control system can display the equipment's working conditions in real-time through a display screen and issue alarms or automatically shut down in case of abnormalities, enhancing the safety and reliability of the equipment.
8. Storage Tank
The storage tank is an important auxiliary component of the screw air compressor, used to store compressed air and stabilize air pressure. The storage tank helps balance the compressor's output fluctuations, ensuring a continuous and stable air supply to downstream equipment.
9. Exhaust Valve
The exhaust valve controls the discharge of compressed air from the storage tank or system, ensuring the system pressure remains within the set range. The design of the exhaust valve needs to be precise to ensure its sealing performance and durability under high-pressure conditions.
The various components of a screw air compressor work together to ensure efficient and stable operation of the equipment. Understanding these parts and their functions helps users perform proper maintenance and operation, extending the equipment's service life and improving work efficiency. Regular inspection and maintenance of these key components can effectively prevent equipment failures and ensure the long-term operation of the screw air compressor.
