What Is a Pneumatic Motor?

An air motor is also called a pneumatic motor, which refers to a device that converts the pressure energy of compressed air into mechanical energy that rotates. Generally used as a source of rotating power for more complex devices or machines. Air motors are classified according to structure: vane air motors, piston air motors, compact vane air motors, compact piston air motors.

There are three most commonly used in the market, namely: vane air motor, piston air motor, gear air motor)

In recent years, air motors have been widely used in various industries, such as drilling in the mining industry, petroleum industry, and drilling of rock holes. The so-called air motor is actually a device that uses the pressure generated by compressed air to convert these pressures into rotating mechanical energy. As the most important part of the air motor, the good performance of the lubrication system will directly affect the work efficiency of the air motor. Judging from the piston air motors currently used in various industries. Its lubricating system usually adopts the method of splash oil lubrication of the oil-throwing pan, but using this kind of lubrication method will greatly restrict the working efficiency of the air motor, and it will not help extend the service life of the air motor. The main cause of this consequence The reason is that the use of oil-throwing plate splash lubrication makes the lubrication system of the air motor unable to accurately control the amount of lubricant during the work process. A drilling equipment company produced a 5 × 135 pneumatic motor, which is mainly used as a power unit of a pneumatic manned winch. For a pneumatic motor, if its lubrication system works well, it can minimize the power loss of the piston friction and the friction loss at the main bearing during its work, so that it can be largely guaranteed Reliability, economy and power of air motor. The main function of the air motor lubrication system is to clean and lubricate parts, when the internal parts of the machine are in relative motion. The lubricating system will send a certain amount of cleaning lubricant to the surface of the part, thereby reducing the resistance caused by friction, which is beneficial to reducing the wear rate of the machine and thereby extending the service life of the equipment. In addition, the cleaning lubricant delivered by the lubrication system helps to clean and cool equipment parts ^[1] .
