How to control a pneumatic motor: 1. Filter and reduce the pressure of the air supplied to the pneumatic motor. The directional control valve needs to supply air to the motor and rotate the motor when necessary. Such valves can be pneumatically controlled, electronically controlled, or mechanically controlled.
Pneumatic motorHow to control:
1. Filter and reduce the pressure of the air supplied to the pneumatic motor. The directional control valve needs to supply air to the motor and rotate the motor when necessary. Such valves can be pneumatically controlled, electronically controlled, or mechanically controlled.
2. When the pneumatic motor is used in applications that do not require bi-directional rotation, it is sufficient to control it with a 2/2 or 3/2 valve. For motors that can rotate in the opposite direction, a 5/3 valve or two 3/2 valves need to be used to ensure that the motor has a supply of compressed air and a discharge of residual air.
3. IfPneumatic motorthere is no need to rotate in a direction, a flow control valve can be installed in the air supply line to adjust the speed of the motor. If the motor is used for reverse rotation, a flow control valve with internal one-way functionality needs to adjust the rotation in each direction. The internal one-way valve allows air from the residual air discharge port of the pneumatic starting motor to be discharged to the exhaust port of the control valve, and then discharged.
4. The compressed air source has sufficiently large pipes and valves to ensure the torque of the motor. At any time, the pneumatic starting motor requires a supply pressure of 6 bar. When the pressure drops to 5 bar, the power decreases.
ReducingPneumatic motorspeed is usually done by installing a flow control valve at the intake, which can also be used as an exhaust when the motor uses the intake. The main exhaust also uses flow control so that speed can be controlled in both directions.
By installing a pressure reducing valve at the upstream air supply, speed and torque can also be adjusted. If low-pressure air is continuously supplied to the pneumatic starting motor and the motor slows down, very low torque will be generated on the output shaft.
Auxiliary savings occur at low speed in one direction, but torque will stick during deceleration. Saving the main intake can achieve deceleration in both directions, but the main intake pressure regulation can be maintained during deceleration whenPneumatic motortorque decreases and speed also decreases.
