Instructions for Using Amro Air Motors
- Air Pressure : Air motors require an air pressure of 6 kg/cm2 for best performance and a pressure of 4 kg/cm2 for optimum performance. Important : The required air pressure should be available at the inlet port of the air motor and not at the compressor. Many a times, the compressor produces the required air pressure, but it drops down considerably at the motor due to long length of the air hose, small diameter of the air hose, number of valves and connections in the air hose etc.
- Air Flow : Each air motor requires a certain volume of air for its operation. The volume is specified by CFM or m3/min. This flow must be available at the motor point for satisfactory running of the air motor.
Therefore, both the airpressure and the volume of air are very important for the satisfactory running of the air motor. - Lubrication: Continuous lubrication is necessary for air motors. Install a lubricator in the airline and adjust the flow of oil in the inlet air for proper lubrication.
- Length of the air hose should be as minimum as possible.
- The ID of the air hose should be approximately of the same diameter as that of the inlet port.
- Do not use right angled air connections to the inlet or exhaust of the air motor. They reduce the flow of the air considerably. Use straight connections.
- Do not use small flow control valves for regulation of speed or torque. Use ball valves of ½" size for motors with ¼" ports and 1" ball valves for ½" ports.
- Use FRL unit of 1/2" size for air motors with ¼" ports and of 1" size for air motors with 1/2" ports
