Compared with the electric motor that plays the same role as it, the air motor is characterized by light outer casing and convenient transportation; and because its working medium is air, there is no need to worry about causing fire; when the air motor is overloaded, it can automatically stop, and the supply pressure Stay in balance. Due to the above characteristics, air motors are widely used in mining machinery, flammable and explosive liquids and pneumatic tools.
Air motors compared to hydraulic motors:
advantage
(1) It is safe to work, has explosion-proof performance, and is not affected by high temperature and vibration;
(2) It can work with full load for a long time, and the temperature rise is small;
(3) The power range and speed range are wide, the power is as small as a few hundred watts, and the power is as large as tens of thousands of watts; the speed can be from several to tens of thousands of revolutions per minute.
(4) Has a high starting torque. Can start with load;
(5) Simple structure, convenient operation, easy maintenance and low cost
shortcoming
(1) Poor speed stability;
(2) The output power is small, the efficiency is low, and the gas consumption is large;
(3) The noise is large and it is easy to generate vibration.
