Role of building construction air compressor

In building construction, the air compressor (air compressor) can be called the “power heart”, and its role runs through the entire project process, which is specifically reflected in the following six core scenarios:

1. Power source of pneumatic tools

• central role: Provides high-pressure air power for air compressors for pneumatic rock drills, pneumatic wrenches, nail guns and other tools.
• efficiency improvement: Compared with electric tools, pneumatic tools have greater power and faster response, especially in drilling, fastening and other operations, and their efficiency is increased by more than 50%.
• typical application：
• rock drilling operation: In rock excavation and foundation pit support, pneumatic rock drills can quickly break hard rock formations.
• Steel Structure Construction: Pneumatic wrenches can efficiently tighten high-strength bolts and ensure the quality of node connections.
• formwork installation: The pneumatic nail gun realizes quick fixing of wooden templates, saving labor time.

2. Key equipment for concrete construction

• sprayed concrete：
• Tunnel/slope protection works: The air compressor provides 0.4-0.6MPa compressed air for the ejector to uniformly spray the concrete mixture to the working surface, with a daily progress of 200 cubic meters.
• special advantages: Avoid traditional pouring formwork support, especially suitable for complex terrain.
• vibrocompaction：
• The pneumatic vibrator eliminates internal voids in the concrete through high-frequency vibration and improves the strength by 20%-30%.

3. Spraying and surface treatment

• Efficient spraying：
• The compressed air drives the spray gun to achieve uniform spraying of fire-retardant coatings and waterproof coatings, with a spraying efficiency of 300㎡/hour.
• fine control: Adjusting the air pressure can control the size of the coating particles and ensure the flatness of the decorative layer.
• surface cleaning：
• During the sandblasting operation, compressed air carries sand to remove rust on the metal surface, and the Sa2.5 rust removal efficiency is tripled.

4. Foundation and pile foundation engineering

• pneumatic pile driver：
• In soft soil foundation treatment, the air compressor provides a continuous high-pressure air source to drive the pile hammer to impact the prefabricated pile, with a penetration speed of up to 2m/min.
• static pressure pile sinking: Through the gas-liquid conversion device, the pile body can sink smoothly and noise pollution can be avoided.

5. Auxiliary operation support

• pipeline purging：
• Before new pipelines are put into production, compressed air is used to remove welding slag and rust to ensure safe fluid transportation.
• tire service：
• The inflation efficiency of tires of construction vehicles is improved to support continuous operations.
• welding protection：
• Provide stable gas source for gas shielded welding and improve weld quality.

6. Environmental protection and intelligent upgrades

• frequency conversion energy-saving：
• The new screw air compressor adopts frequency conversion control, saving energy by more than 30% and reducing carbon emissions.
• waste heat recovery：
• Some models can recover compression heat for domestic hot water at construction sites, and the overall energy efficiency is improved by 15%.
• remote monitoring：
• Real-time monitoring of equipment status is realized through Internet of Things technology, and the fault warning accuracy rate exceeds 95%.

summary: Air compressors are not only power providers in construction, but also guarantors of efficiency and quality. From foundation treatment to decoration, its application covers more than 90% of the construction process. With energy-saving technologies and intelligent upgrades, air compressors are further promoting the development of the construction industry in a green and efficient direction.
