Piston pneumatic motors are often used in papermaking, metallurgy, chemical industry, light industry and other occasions. They are suitable for industrial transmission occasions with frequent start-up and conversion, high temperature, humidity and large load

Air pressure: when selecting a pneumatic motor, please note that the technical specification list only indicates the output parameters of the motor at the standard working pressure of 0.62mpa. The output capacity of the pneumatic motor is greatly related to the air pressure provided at the work site. By adjusting the pressure, air supply and exhaust, the same motor can achieve different output speed, torque and power within a certain range. When the air supply pressure of the motor is lower than 0.25MPa, its performance may not be stable. Usually, the specification of the pneumatic motor is selected based on 70% of the technical parameters. This allows additional power for start-up and possible overload.

High power: Generally speaking, the pneumatic motor outputs high power when the speed is about 50% of the no-load speed

Working speed: when selecting pneumatic motor, the working speed should be considered first rather than idle speed

Note: the pneumatic motor should not idle for a long time. The performance curve in this catalogue only refers to the high speed that the motor can achieve in theory. Generally, it is not recommended to operate under this condition

Working torque: the same important technical parameter as the operating speed of pneumatic motor is working torque. Speed and torque together determine the required motor power. When selecting pneumatic motor, we must pay attention to the difference between locked rotor torque and working torque

Speed and torque: the starting torque is about 75% of the locked rotor torque. The operating torque or rated speed torque at any speed can be close to the motor performance curve or calculated by the following formula: torque (nm) = power (kw) * 9550 / speed (RPM) air system, air supply and flow: once a pneumatic motor is selected, it is important to ensure that the required air pressure can be provided to the motor when the motor is running, Due to possible pipeline losses in the air system, the pressure reading on the compressor does not mean that the running pneumatic motor will reach the same pressure. Exhaust throttling may also affect the operation of the pneumatic motor, which is often the cause of failure.

Air inlet control: when installing a reversible pneumatic motor, a quick exhaust valve should be used to prevent poor secondary exhaust.

Replace the motor with a pneumatic motor: except for the DC series wound motor, the performance curve of the motor is completely different from that of the pneumatic motor, so their torque and speed curves cannot match.
