The industry's need for hydraulic and pneumatic systems is very evident these days, and hydraulic and pneumatic systems such as hydraulic jacks, gear and piston hydraulic pumps, pneumatic jacks, pneumatic pumps, etc., which work with greater speed and better performance instead of the old mechanical systems.
The conversion of energy into mechanical movement can be considered as the main task of hydraulic and pneumatic systems, but pressure control by pneumatic solenoid valves and pneumatic pressure control valves and Hydraulics is also one of the other applications of these systems.
What is pneumatics?
Pneumatics is one of the types of energy that is now widely used in various industries and it can be said that today there are few factories or industrial centers that do not use pneumatics and in this century it is one of the types of proof is energy, and man has traveled the path of industry by trusting it.
Pneuma in Greek means wind breathing and pneumatics is a science that talks about air movements and events, nowadays pneumatics Among the craftsmen, it is known as a very clean, low-risk and cheap energy, and it is widely used.
But in contrast to pneumatics, there is a hydraulic system, which can be said to have the same function as pneumatics, but The way it works is different from the pneumatic system that we have explained below.
What is hydraulic?
Hydraulics is derived from the Greek word "Hydro" which means the flow of fluid movements. It was mostly about the use of water, water wheels and water engineering.
The concept of hydraulics in this century is no longer limited to water but has gained a wide scope and includes liquid foundations and applications. The other is, in particular, "oil", because water cannot be used as energy to transfer motion in industry due to its corrosive and rusting properties. Nowadays, oil is used in industry and in hydraulic systems.
Advantages of pneumatic system
1- The main factor of pneumatic system performance is air, and air exists everywhere on the planet.
2- Pneumatic purity Compared to hydraulics, it is more due to the use of gas and air in pneumatics. (In industries such as pharmaceuticals and food products that require a lot of cleanliness, pneumatics are used more) and the change of direction which is done with the help of a pneumatic solenoid valve (this component is very important)
5- High security of the pneumatic system due to the non-flammability of this system and the absence of spark
6- Running speed higher than hydraulic system
Advantages of hydraulic system
1- High strength and strength
2- Installation or repair The components of the hydraulic system are very easy.
3- Fast and easy start of the hydraulic system even when loading.
4- The ability to convert rotary movement into linear movement and vice versa.
5 - The ability to turn quickly in the direction of movement, even under load. 6- High energy production with a small piston hydraulic pump in terms of weight and volume. 7- Long life of hydraulic parts or elements due to Lubrication.
8- Speed and power in hydraulic system
9- The possibility of implementing industrial automation on hydraulic systems
