Working environment

The design of pneumatic fittings should allow the free flow of required air or gas without any opportunity for significant drops in pressure. Pipes and hoses should be configured as simply as possible, so that no energy is lost in the air’s passage through the system. Always use straight runs wherever possible, and only use elbows and Ts if absolutely necessary.

When choosing your pneumatic fittings, there are some key environmental factors that must also be taken into account.

OPERATING TEMPERATURE

The operating temperature specified by the manufacturer defines the range of temperatures or the operational temperature ratings within which the particular fitting is designed to work. This is measured in degrees Celsius (°C) or degrees Fahrenheit (°F), and the fitting may well fail if it is made to operate above or below this specified range. It must be borne in mind that the ambient temperature of the inlet air to the compression unit will affect the compressed air output.

As air heats up or rises the pressure drops, so industrial automation equipment should generally only be used in a controlled temperature environment. In general terms, every 5º F of temperature reduction produces a 1% improvement in efficiency and power conservation, but both high ambient air temperature and low intake pressures will significantly affect performance. It’s also a fact that an increase in operating temperature will cause a reduction in the operating pressure of polyurethane and nylon tubing.

CONTAMINANTS

The most common air contaminants are water, oil and particulates, such as dirt, rust and metal shavings. Such contaminants in the air intake are commonly removed by the filtration system, usually comprising a filter-regulator-lubricator unit (FRL). The lubricant also acts as a coolant in some types of compressor, but there is sometimes a danger of the heated lubricant getting back into the inlet air and causing contamination there. Additional contaminants in the form of bacteria or microorganisms can also be critical in some types of application, such as pharmaceuticals or food.

PHYSICAL SPACE

It seems simple, but it is essential to ensure that there is sufficient space around the installation to allow the best configured construction, as well as access for maintenance and repairs. It should be large enough to allow pipework to run naturally, and to permit a free flow of ambient air so the space doesn’t overheat externally. The equipment also needs to be stable with no possibility of vibration.

Sensors are a means of providing feedback to a control system, so that the operating parameters of an application can be continually adjusted for optimal results. Pneumatic cylinder sensors can be used to measure various parameters. Their typical function in pneumatics is to detect the position of a pneumatic cylinder during its operation by means of proximity switches.

What Is A Pneumatic Cylinder Sensor?

The phrase “pneumatic cylinder sensors” usually refers to position sensors, which are important in applications where the piston’s linear position is critical. Position feedback is provided by sensors mounted on the cylinder. It’s passed to the control system so that it can make necessary operational adjustments. Sensor proximity switches can be of an inductive mechanical type, but more common is a magnetic proximity switch and position transmitter connected to a control system.

WHAT ARE PNEUMATIC SENSORS USED FOR?

The sensors deliver electrical signals via a transmitter, reporting the piston’s position to a control system. The feedback provided by position sensors offers an additional layer of security, ensuring that the piston is ideally placed to drive crucial applications.

Types Of Pneumatic Sensors

Pneumatic cylinders also use other sensors, including those measuring airflow and pressure, but we’re focusing on position sensors. Of these, magnetic proximity sensors are probably the most common type. They’re mounted onto the cylinder body, where they can detect the magnetic field generated by the piston’s integral magnet. They indicate its proximity by relaying an ON or OFF signal to the control system.

The sensors can be mounted in various positions on the cylinder body to detect extension and retraction of the piston. They can also be mounted at one or more specific positions for more precise sensory input. The type of sensor you choose and the way they’re mounted will depend on whether you have a round or a rectangular (profile) cylinder body.

Tubes are relatively rigid vessels generally made from one solid material, typically some kind of thermoplastic, which can also be internally reinforced for higher strength:

• Nylon is light, tough and dimensionally stable, with low water absorption and high resistance to flexural fatigue.

• Polyurethane is flexible, strong, resistant to abrasion and kinks and can also withstand contact with oils and fuels.

• Polyethylene and high density polyethylene (HDPE) are widely resistant to solvents and chemicals, and relatively cheap with good flexibility.

• Polypropylene withstands UV radiation, is resistant to chemical attack and can be formulated for use in food-contact applications.

• PVC and CPVC (chlorinated polyvinyl chloride) is light and usually more flexible than polyethylene or nylon, with a good resistance to chemicals, and can sustain repeated sterilisation. It is also usually transparent, enabling visual confirmation of flow.

Hoses are completely flexible vessels constructed from a variety of the same thermoplastic materials. An inner tube is reinforced with one or more layers of spiral-wound or braided fibres, with a protective outer cover. Hose is generally more expensive than tubing but is more rugged and durable, as it is often used for manual tools and gets dragged across abrasive surfaces.

Pneumatic transmission and control technology, referred to as pneumatic, is the compressed air as the working medium to carry out energy and signal transmission, is to achieve a variety of production process, automatic control of a technology.  It is an important part of fluid transmission and control.  In recent decades, pneumatic transmission technology has been widely used in industrial automation and labor-saving, and has played a very important role in promoting the development of automation.  Pneumatic has many advantages in practical application  

1. Easy to use  

 

Air as a working medium, air everywhere, convenient source, directly discharged into the atmosphere after use, will not pollute the environment, can be set less or do not have to set back air pipeline.  

 

2. The system is easy to assemble  

 

The use of quick couplings makes piping very simple, so system assembly, maintenance, and component replacement are simple.  

 

3. It’s quick  

 

Quick action and quick reaction, can reach the required pressure and speed in a short time.  Under a certain overload operation can also ensure the safety of the system, and is not easy to overheating phenomenon.  

 

4. Safe and reliable  

 

Compressed air does not explode or catch fire and does not require expensive explosion-proof facilities to be used in flammable and explosive places.  Can be safely and reliably used in flammable, explosive, dust, radiation, strong magnetic, vibration, impact and other harsh environment.  

 

5. Easy storage  

 

The air pressure has a high self-holding capacity, compressed air can be stored in the gas tank, ready to use.  The pneumatic system maintains a stable pressure even when the compressor stops running and the valve is closed.  Therefore, the continuous operation of the compressor is not required.  

 

6. Long-distance transmission  

 

Because the viscosity of air is small, the flow resistance is small, the pressure loss of air flow along the pipeline is small, which is conducive to the concentrated supply of media and long-distance transportation.  Air is easily piped, regardless of distance.  

 

7. Overload protection  

 

Pneumatic mechanism and working parts can be overloaded and stop, so there is no danger of overload.  

 

8. Clean   

 

Basic pollution-free, for the requirements of high purification, pollution-free occasions, such as food, printing, wood and textile industry is very important, pneumatic has a unique adaptability, better than hydraulic, electronic, electrical control.

One of the important parts of the pneumatic components is the cylinder. In order to ensure the normal use of the cylinder and avoid unnecessary situations, for the use of the pneumatic components and cylinder, let’s check the right way to use cylinder. When using the cylinder, the air quality requirements are very high. Clean, dry compressed air should be used. The air should not contain organic solvents, synthetic oils, salts, corrosive gases, etc., in order to avoid bottle and valve failure.
