Plant manufactory pneumatic actuators and pneumatic automation
In machine automation a pneumatic system provides a simple and cost-effective means to move, clamp, rotate, grind and screw. A pneumatic system is a collection of interconnected components using compressed air to do work for automated equipment. Examples can be found in industrial manufacturing, a home garage or a dentist office. This work is produced in the form of linear or rotary motion. The compressed air or pressurized gas is usually filtered and dried to protect the cylinders, actuators, tools and bladders performing the work. Some applications require a lubrication device that adds an oil mist to the closed pressurized system.VIDEO ON THE TOPIC: How a Industrial Pneumatic Systems Work And The Five Most Common Elements Used

Pneumatics for Mechanical Motion
The debate surrounding the pros and cons of electric and pneumatic actuators has been raging for years and still no easy answer exists.
Here, with the help of Bimba Manufacturing, we focus on the core differentiators to help narrow your decision. If there is any significant performance differentiator, it is that electric actuators are better known for their high levels of precision.
Though this is not to say pneumatic actuators cannot deliver very precise motion. Again, the issue here revolves around how much precision you really need. For help on this issue, we referred to information from Bob Kral at Bimba Manufacturing Company, a supplier of pneumatic, electric and hydraulic actuators.
According to Kral, the choice of pneumatic or electric actuators involves an evaluation of performance, component costs, system costs, and productivity gains. The two technologies are so different that one cannot be a drop-in replacement for the other. Each has inherent advantages and disadvantages. The case for pneumatic actuators Pneumatic actuators provide high force and speed at low unit cost in a small footprint. As a matter of fact, pneumatic cylinders provide more force and speed per unit size than any other actuator technology except hydraulic.
Force and speed on pneumatic actuators are easily adjustable and are independent of each other. Pneumatic actuators are most economical when the scale of deployment matches the capacity of the compressor. Small compressors are efficient and economical when used to power a small number of pneumatic devices. Large compressors are efficient and economical when powering a large number of pneumatic devices. While pneumatic component costs are low, maintenance and operating costs can be high, especially if a serious effort has not been made to quantify and minimize the costs.
Maintenance and operating costs include replacement cylinder costs, air line installation and maintenance, and electricity for the compressor. According to the Department of Energy, 24 percent of the annual cost of compressed air is due to maintenance, equipment and installation while 76 percent is due directly to the cost of electricity for the compressor. Determination of the operating cost per pneumatic device deployed in a facility can be eye opening, especially if cost calculations have not been done for a while and the scale of operations has shrunk.
The case for electric actuators In contrast to pneumatics, electric actuators provide precise control and positioning, help adapt machines to flexible processes and have low operating cost. They are most economical when deployed in a moderate scale in processes where their performance advantages can be a benefit and when the electronics are separate from the actuator to segment and minimize replacement costs.
Electric actuators consist of a ball, acme or roller screw connected via a coupler to an electric motor. As the screw turns it moves a piston, which is connected to the rod or carriage. The rod or carriage moves the load. Performance varies depending on materials used. Commonly used motors for electric actuators include steppers and servos.
Brush dc motors and ac motors are sometimes used with limit switches when positioning accuracy is less critical. Step motors are an economical choice for accurate positioning at lower speeds. However, steppers may lose synchronization with the controller when employed open loop without an encoder or if they are undersized for an application.
Servos, by definition, are closed loop and provide superior performance at high speeds, albeit at a higher cost. High precision screws and anti-backlash mechanics can provide accuracies to ten-thousandths of an inch.
Standard precisions with standard components range from a few hundredths to a few thousandths of an inch. Components of an electric actuator include the mechanical actuator that translates motor rotation to linear speed and thrust, the motor, an electronic driver or amplifier to power the motor, and a controller to control motion.
Operating costs of electric actuators are largely due to motor power draw. While component costs of electric actuators are high, operating costs are low. High component costs often deter the use of electric actuators because savings in operating costs compared to pneumatics are often not adequately considered or are outright ignored. Cost comparison To better compare actual costs between pneumatic and electronic actuators, consider this example: Manual changeovers adapting a production line to a different product can be expensive in terms of both lost production and man-hours required to implement the change.
Because electric actuators can substantially reduce changeover costs largely due to the fact that they can retain condition settings , the annual cost savings associated with changeovers must be considered as part of the implementation decision. See the complete Bimba Manufacturing Company white paper comparing pneumatic and electric actuator options, which provides in depth details on operating cost calculations.

What are Pneumatic Cylinders and Actuators?
An engineering system contains multiple components that interconnect to perform a specific task. Starting from basic fundamentals through to advanced applications, Sensors and Actuators: Engineering System Instrumentation, Second Edition thoroughly explains the inner workings of an engineering system. The text first provides introductory material—practical procedures and applications in the beginning—and then methodically integrates more advanced techniques, theory, and concepts throughout the book.
In manufacturing facilities, compressed air is so widely used that it is often regarded as the fourth utility after electricity, natural gas and water. The main reasons are lower upfront and maintenance costs, which combine to make pneumatics the most popular and cost-effective choice for executing mechanical motion. Linear power transmission is typically done with fluid pneumatic with air or hydraulic with oil or electric power. In electric power systems, electromechanical devices such as belts, pulleys, chains, sprockets and clutches convert rotational motion from motors to linear force. The main exception is linear motors, a relatively expensive specialty technology used to move very light loads.
Employing fluid power to achieve mechanical motion can be implemented via hydraulics using uncompressible liquids or via pneumatics using compressible gasses; typically, air. The latter provides several distinct advantages, making it a popular choice for many mechanical applications. In most facilities, the most basic utilities are electricity, natural gas, and water. Many users find compressed air is a convenient fourth utility, usually produced by using electricity. This article examines pneumatic advantages in industrial applications. Automated equipment may employ a myriad of motion tasks such as clamping, gripping, positioning, lifting, pressing, shifting, sorting, and stacking. Most of these are two-position actions with repeatable end stops, but multi-position actions are often also required. Even more advanced are adaptive uses — possibly including closed-loop control for more precise positioning — such as tensioning, pressing, labeling, embossing, crimping, and cutting. Pneumatics are well suited for moving and holding parts and tooling for industrial machinery and processes.
