Rotary Screw Air Compressor Offering Efficient and Reliable Air Flow For Industrial Applications

Rotary screw air compressors are indispensable tools in many industries for powering critical tasks like jackhammers and pneumatic tools, providing consistent factory production processes with air.

Inside this system, two meshing screws trap air between their rotating vanes, pressurizing it as they turn. Oil provides cooling and lubrication benefits while creating a hydraulic seal between each screw for greater effectiveness.

Efficient Air Flow

Rotary screw air compressors employ a straightforward system for producing high volumes of compressed air: an opening valve draws air in through an intake vent into their chamber where two intertwining screw rotor elements interlace to trap and isolate the trapped air before rotating to move it down into compression; once at their endpoints they open up and release their hold on it.

Once compressed air is ready to use, it is cooled and distributed via air lines or an air receiver tank. For applications requiring different pressure levels, variable-speed rotary screw compressors adjust their motor speeds according to demand for air.

Oil-injected rotary screw compressors may provide higher PSIG levels and run cooler than oil-free models, yet their oily lubrication could contaminate processed air for food-grade and pharmaceutical use. Brabazon offers several oil-free rotary screw air compressor models designed to meet specific operational and efficiency requirements.

Reliable Air Flow

Screw compressors offer steady air flow to support operations without interruption, thanks to their unique design that effectively manages heat and prevents it from overheating – an issue common among other types of air compressors.

Lubricating oil serves to seal off the gap between rotor vanes, providing both hydraulic sealing and mechanical energy transfer between driven and undriven rotors. Furthermore, this cooling agent keeps components at their optimal temperatures. Once compressed air and oil reach a separation stage, separated air is then cooled, filtered, and sent back through air lines while oil drains into an air receiver tank for recycling.

Oil-injected rotary compressors produce higher PSIG while remaining cooler due to the oil providing both sealing and cooling benefits. They’re often seen used in manufacturing facilities or auto body shops for powering pneumatic tools and equipment, such as those found in large manufacturing plants or for automotive and auto body repair shops. If compressed air comes into contact with pharmaceutical products, medical research, food or beverage items then an oil-free model would ensure optimal air purity levels.

Low Maintenance

Contrary to reciprocating air compressors, screw air compressors require minimal maintenance and provide consistent air flow with low total cost of ownership.

These units are quieter than other forms of air compressors, making them perfect for industrial settings that prefer more peaceful surroundings. Furthermore, their compact footprint takes up less floor space than other kinds of air compressors.

Screw air compressors use two interlocking helical screws, or rotors, to compress air. They’re powered by a drive motor and an air/oil separator; during compression oil is used to lubricate and cool the rotors before being separated out with the compressed air output. You can choose from oil-injected or oil-free models depending on your specific needs; oil-free models may be ideal when air quality matters such as in pharmaceutical or food and beverage manufacturing environments.

Энергоэффективность

Rotary screw air compressors use less energy and have greater stability, minimizing pressure fluctuations that reduce efficiency and cost.

Modern rotary screw compressors feature sophisticated controls that adapt operational parameters like speed and pressure according to actual demand, for optimal energy performance. Asymmetric screw profiles also help improve energy efficiency by minimizing internal leakage at high speeds – this leads to better energy performance overall.

Oil-flooded designs use lubricating oil as an insulator between rotor vanes to lubricate and seal compressor components, transfer mechanical energy, and cool the air. An external gear synchronizes counter-rotating rotors so they do not come into contact, while in oil-free models the air passes through an air filter before returning back into the compressor system – providing clean compressed air suitable for critical applic
