Tips: The Working Principle of Pneumatic Vane Air Motor.
Open the manual reversing valve, the gas with a certain pressure reaches the air distribution plate through the air-controlled reversing valve. At this time, the gas with a certain pressure enters the motor in two ways: the first way, the pressure gas enters the brake chamber and pushes it away Brake piston; the second way, the pressure gas enters the motor chamber from the motor air inlet 1.
The pressurized gas generates pressure on the blades and overcomes a certain friction force to push the motor rotor to rotate. When the blades leave the air inlet 1 behind the chamber, the chamber is at a critical position a. As the motor rotates, the pressurized gas in the chamber performs adiabatic expansion. Work externally. When the front vane of this chamber reaches the main exhaust port 2, the adiabatic expansion of the chamber is over and it is at the critical position b. With the rotation of the motor, the chamber enters the main exhaust area for main exhaust. When the rear vane of this chamber leaves the main exhaust port 2, the main exhaust of this chamber ends and enters the critical position c. Then, the chamber undergoes adiabatic compression stage. When the front vane of the chamber reaches the secondary exhaust port 3, the chamber is at the critical position d. With the rotation of the motor, the chamber enters the secondary exhaust area for secondary exhaust. When the rear vane of the chamber leaves the auxiliary exhaust port 3, the auxiliary exhaust of this chamber ends and the next cycle is entered. In this way, the vane-type air motor can continuously rotate and output the speed and torque outward.
