Is there any industry that you know of that doesn't require any movement or force? I think almost every industry needs movement or force to hold, shape or compress products. This means that you can find fluid power applications in many industries.
Fluid power is a technology that produces, transmits and controls the system using pressurized fluids. Hydraulic, pneumatic and electrical are the three important power transmission technologies currently in use. Among them, hydraulic and pneumatic are included in the scope of fluid power. Dec. A fluid power system will transfer fluids from one part of the system to another part to generate force. In this article, we can discuss the differences between hydraulics and pneumatics.
Both work by using the same technology to generate power or force. But the medium it uses to convert mechanical energy will be different. The hydraulic system uses pressurized liquids such as petroleum oils, synthetic oils and water. In the case of a pneumatic system, it uses compressed gases or air. This is the main difference Decoupling between hydraulic and pneumatic system.
You can find examples of pneumatic and hydraulic systems in your daily life. The operation of the lungs is an example of the pneumatic system, and the blood flow is an example of the hydraulic system. Hydraulics has other applications in dams, car brakes and steering, amusement parks, machine tools, elevators and much more. Dentistry, mining, air brakes, nail guns and robotics are some of the applications of the pneumatic system.
Pneumatic and Hydraulic
Hydraulic systems are designed as a closed system and pneumatic systems are designed as an open system.
The working pressure of the pneumatic system is 100 psi, and the working pressure of the hydraulic system is 500 to 5000 psi.
Hydraulic systems must be self-lubricating (because they use different types of oils), while the pneumatic system requires separate arrangements for the lubrication of the system.
The reservoir, pumps, valves used to store and pump liquids in the hydraulic system make the system larger and more complex. Therefore, larger components require more pressure, which makes the hydraulic system more expensive. The maintenance and repair of hydraulic systems are more complex than pneumatic systems. Pneumatic systems are simple, inexpensive and economical.
It is possible for a hydraulic system motor to start the engine under high load. In addition, hydraulic systems provide very slow, precise and linear movement. Operations that are too slow for a pneumatic system cause concussion.
Leakage in the hydraulic system will make the working environment messy. In addition, leakage of pressurized liquids is dangerous for both employees and machines. For the hydraulic system, leakage will slow down the system performance. However, the pneumatic system is affected by leakage.
Some hydraulic oils are petroleum-based. There is a risk of fire in hydraulic systems. However, there is no fire hazard in pneumatic systems.
Valve operations of pneumatic systems are easier than hydraulic systems.
The air compressor is a basic component of the pneumatic system.
