460V 20HP Screw Air Compressor 15KW 3PH 125 PSI 81CFM Outlet NPT 3/4

  
Motor Power: 20 horse power. (F)NPT Outlet: NPT 3/4. Pressure: 125 psi / 8 bar. A rotary screw air compressor enacts positive displacement using twin spiral screws. The more common type of rotary screw compressor, fills the space between the helical rotors with an oil-based lubricant. Which transfers mechanical energy and creates an air-tight hydraulic seal between the two rotors. The atmospheric air enters the system, and the interlaced screws push it through the compressor. How Do Rotary Screw Air Compressors Work? All compressors work using a mechanical element that physically reduces the volume air takes up, compressing it. In a rotary screw compressor, that mechanical component is a pair of screws. These two screws are meshed together and turn continuously. Air enters and is then compressed in the gap between the screw threads.

Most rotary screws are oil-flooded. Although oil-free screw compressors are available. Here's how oil-flooded rotary screw compressors work. Air enters the compressor through the inlet valve. Air then travels through the pressure control line and into the regulator valve.

This process sets the air pressure for the system. Both oil and air enter the compressor, where they combine into a mist.

Air travels the length of the matching rotary screws and becomes compressed. After exiting the compressor, the air and oil mist enters the primary oil separator tank. The tank uses centrifugal force to make the oil molecules come together, forming droplets that fall to the bottom of the tank.

The oil can then be recycled into the air compressor for the next batch of air. The air then enters a secondary separation filter, which further purifies the air and removes more of the oil. The oil-free air then exits the system, into a reserve tank or the connected air tools or machinery.

The oil travels from the separator tank to an oil cooler. Benefits of Rotary Screw Air Compressors. There are many advantages of rotary screw compressors. They are the compressor of choice for a wide range of compression applications across many industries.

Continuous airflow and pressurization: Many air compressors generate excess heat and need to cycle off to maintain the machinery. Rotary screws can turn continuously and experience little to no downtime.

Features a programmable control system. Reduces your air system footprint and allows for easy maintenance. Please read the operate manual carefully before start the compressor working. Don't dismantle any connector or equipment when machine is. Otherwise, the high-pressure gas and high temperature will. Please pay more attention to parts such as pump, oil tank and. Pipelines, because they are high temperature when machine is running. Don't try to change the working pressure rated. Working pressure exceeding the rated range will cause machines to. Overload and stop to work. Provide proper grounding connection for electric parts according. Use suitable wires matching the.

Working power, otherwise they will burnt out due to high temperature. Or some other dangerous events occur. The compressed air for breathe use is prohibit.

Every 50 hours or weekly. Check intake filter, if necessary clean it. Drain condensation water from oil tank.

Check and adjust belt tension if necessary (belt driven only). Replace lubricants (for mineral lubricants oil). Replace lubricants (for synthetic lubricants oil). Replace filter element and lubricant after first 500 hours of operation.

Use incorrect lubricant oil and spare parts will cause compressor damage, only use original. The service life of compressor depends on the environment conditions such as dust, vent etc. Easy maintenance: Some rotary screw systems are manufactured with up to 70% fewer parts than other compressors.

This design drives down maintenance costs. More power: Rotary screws have extremely high airflow rates. They can run tools and heavy equipment efficiently with impressive horsepower. Safer at extreme temperatures: Many rotary screws can pressurize air in both high and low temperatures. Energy-efficient: Rotary screws produce less heat, conserve more energy and consume less oil than most compressors.

These features preserve the machinery for many years and keep the lifetime cost of the compressor low. If you have any problems, please contact the customer service.
