Mechanics for Controlling the Speed of a Pneumatic Cylinder
How does air compare with oil? Air is the only way to go!
Traditionally, pneumatic cylinder speed control has used air over oil. The speed is controlled by an air valve mounted on top of an oil reservoir, which is operated by air pressure. Kellypneumatics Mass flow controllers eliminate the need for an oil reservoir. For controlling the speed of the cylinder, you simply need compressed air.The speed of a pneumatic cylinder can be controlled using an electronic pressure regulator (EPR) or mass flow controller (MFC). EPRs are used to control the air pressure within the cylinder, while MFCs are used to control the flow of air into the cylinder. Both devices can be used to improve the repeatability and accuracy of the pneumatic system.
EPRs are more commonly used to control the speed of pneumatic cylinders. They work by regulating the amount of air that is allowed into the cylinder. This allows for precise control over the speed at which the piston moves. EPRs also have the ability to maintain a constant pressure within the cylinder, which helps to improve repeatability. MFCs work by controlling the flow of air into the cylinder. This can be done by either regulating the pressure of the air that is being supplied to the cylinder or by restricting the airflow into the cylinder. MFCs are less common than EPRs, but they can provide better control over the speed of the piston.
Both EPRs and MFCs have their advantages and disadvantages. EPRs are more commonly used because they are more precise and easier to use. MFCs can provide better control over the speed of the piston, but they are more difficult to use. Electronically controlled pneumatic cylinders offer many benefits over traditional oil-based systems. Electronic control provides greater repeatability, improved control, and increased efficiency. Electronic systems are also less likely to leak, making them more environmentally friendly.
Pneumatic cylinders offer several advantages over other types of actuators. Pneumatic cylinders are relatively inexpensive, have a low maintenance cost, and are simple to use. Pneumatic cylinders are also able to generate high force levels and can be used in a variety of applications.
Pneumatic cylinders are often used in applications where precise speed control is required. In order to achieve the desired level of control, a pneumatic system must be equipped with an Electronic Pressure Regulator (EPR) and Mass Flow Controller (MFC).
The EPR is responsible for regulating the pressure of the air within the system. This ensures that the air pressure remains consistent, even as the demand on the system changes. The MFC, on the other hand, controls the flow of air within the system. By regulating both the pressure and flow of air, the EPR and MFC work together to provide precise control over the speed of a pneumatic cylinder. There are many benefits to using an EPR and MFC for pneumatic cylinder speed control. First, they provide a high degree of accuracy and repeatability. This is important in applications where precise control is essential, such as in the medical field.
Second, EPRs and MFCs are relatively low maintenance. Once they are installed, they require little to no upkeep. This is in contrast to other methods of speed control, such as mechanical governors, which can be susceptible to wear and tear and require regular maintenance. Finally, EPRs and MFCs are relatively inexpensive. When compared to other methods of speed control, such as hydraulic systems, they offer a more cost-effective solution.
