An enjoyable trip in the world
of hydraulics and hydraulic parts.
Browsing 'hydraulic parts' page will improve your hydraulic skills and knowledge.
With the help of my experience I went through I will share useful date about hydraulic systems.
History of hydraulics
The Greek word 'Hydra' refers to water while 'Aulos' means pipes. The hydraulics word it comes from Greek by combining these words, which in simple English means, water in pipes.
Man has been aware of the importance of hydraulics since ancient times. In fact even as early as the time period between 100 and 200 BC, man had realized the energy potential in the flowing water of a river. The principles of hydraulics were been in use even in those early times, in converting the energy of flowing water into useful mechanical energy by means of a water wheel.
For accurate control of force, six types of pressure control valves have been develop.Pressure relief,pressure reducing, sequencing, unloading, brake and counterbalance valves control.
A common valve that can be found in most of the hydraulic system is:directional control valve.
Flow control valve
Flow control as the name implies controls the flow of fluid in a hydraulic system.Continues
Check valves locks the cylinder
Check valve is a simple but an important hydraulic component of a hydraulic system.
A multiple orifice device named shock absorber valve
A shock absorber is a device that brings a load in motion to a gentle rest through the use of metered hydraulic fluid.Continues.
Servo valves are an important hydraulic part which is a direction control valve that has an endlessly variable positioning capability. It controls not only the direction of the fluid flow but also the quantity.Continues.
Hydraulic accumulator is improving hydraulic efficiency
Hydraulic accumulators store energy - holding the fluid pressurized. Continues
The reservoir serves an important role in maintaining the efficiency of fluid transfer and conditioning.Continues
Air in the Hydraulic system
Air is the only gas commonly used in hydraulic systems because it is inexpensive and readily available but if it is not taken seriously it may causes trouble within the system.
Some inconvenience will arise when entrapped air is part of the hydraulic system. I’ll summarize below some effects of entrapped air and why we have to remind his actions in maintenance routine.
A strainer does more harm than good?
Some says that are useless because they are increasing the chances of cavitation and are doing more harm than good to the system.
