We will answer all these questions in the article below.

Structure of Chicago Pneumatic screw air compressor

• Electric motor and coupling: Most screw compressors use 3-phase motors to convert electrical energy into mechanical energy.
• Valve: Regulates the flow of compressed air into the machine.
• One-way valve: Allows gas to flow in one direction only, installed at the outlet of compressed air.
• Oil stop valve: Prevents oil from spilling from the compressor head to the motor when the machine is not in operation.
• Minimum pressure valve: Maintains a minimum pressure in the oil tank and functions similarly to check valves.
• Thermostat valve: Regulates the amount of lubricant going up on the cooler.
• Solenoid valve: Opens and closes the suction neck.
• Safety valve: Ensures the machine is safe from short-circuits and fires.
• Oil tank and oil separator: Stores engine oil and removes machine oil from compressed air to ensure air quality.
• Oil return pipeline: Collects oil at the bottom with a filter to separate the oil left after the filtration process.
• Oil filter: Filters dirt in the oil, installed between the oil tank and the screw.
• Primary filter: Limits the impact of sand, gravel, dirt, etc., on the machine.
• Cooler: Cools the compressed air before it is released from the container.
• Oil cooler: Cools both oil and compressed air, located next to the cooler.
• Cooling fan: Blows air around the oil and compressed air coolers.
• Pressure sensor: Controls the pump to operate within the rated pressure range.
• Temperature sensor: Measures the machine's temperature and gives warnings if it is too high.
• Overload sensor: Protects the machine from short-circuits, fires, and misoperation.
• Various other parts such as switches, LCD control screen, protective cover, etc.

Principle of operation of the Chicago Pneumatic screw air compressor

Working mechanism: Uses a positive rotation mechanism, twisting from bottom to top, from outside to inside to create higher pressure. Works based on continuous volume change, with two axes as the center of gravity, including a large shaft and a small shaft.

In the compressor head of the screw air compressor system, there are 2 screws, 1 main shaft, and 1 auxiliary shaft. These two shafts have tooth grooves that engage each other. The number of teeth between the two shafts differs by 1-2 teeth.

When the air compressor starts, the pair of gears disengages, creating a large space in the middle cavities of the gears. This space is connected to the intake and filled with air. The air intake process stops when the gas chamber is fully expanded and the gas volume reaches its maximum value.

When the shaft rotates at a fast speed, air is sucked into the housing through the intake port and directly into the air cavity between the two shafts. This cavity narrows thanks to the tightening gears, reducing the gas volume and increasing the pressure. A check valve is installed at the outlet to prevent the compressed air from flowing back and limit leakage.

Applications of screw air compressor

• In the industrial electronics industry: Compressed air from the screw air compressor is used in the manufacturing and assembly of electronic components.
• In the manufacturing industry: Compressed air is used to control automation equipment.
• In the construction industry: Provides compressed air for transporting and spraying concrete in situations where concrete mixers cannot be used.
• In the mining industry: Supplies clean compressed air containing oxygen to tunnels, mines, etc., for workers.
• In the medical industry: Dries and sterilizes medical equipment, dries drugs, creates an ideal environment in biochemistry rooms, and supplies compressed air for equipment such as X-ray machines.
