Fluid Power – Fascinating Points (#1)

Fluid power provides the muscle for various work operations involved in stationary as well as mobile applications. As we can see, the use of fluid power is widespread in many applications. Many of the operators, technicians, and engineers are ignorant of the operational, maintenance, and safety aspects of fluid power. Therefore, proper training is essential for handling fluid power systems.

Fluidsys Training Centre, Bangalore provides training in the field of fluid power in a systematic manner. Hydraulic and pneumatic courses are offered by us to meet the contemporary needs of the industry as well as educational institutes. Further, the training centre is providing blogs covering technical information on fluid power. Hope these blogs will benefit especially the new entrants in the field of fluid power.

Snippet #1 Hydraulic Power Transmission System

Pure hydraulic systems can handle a vast amount of forces with compact components. They offer good controllability and resistance to shock loads. The electro-hydraulic techniques augment the outstanding advantages of pure hydraulics. Electro-hydraulic systems can easily be interfaced with PLCs. Moreover, simple, flexible, and versatile hydraulic systems can be developed using cartridge valves. All these advantages have made hydraulics the preferred technology for industrial, mobile and other applications.

Snippet #2 Fire-resistant Fluids

ISO 6743-4 divides fire-resistant fluids into HFA, HFB, HFC, and HFD

HFA· Oil-in-water emulsions with a combustible proportion of 20% maximum
HFB· Water-in-oil emulsions with a combustible proportion of 60% maximum
HFC· Water glycol solutions with a water proportion of at least 35%
HFD· Water-free fluids on a synthetic base

Snippet #3 Basic Requirements of Fluid Conductors

Hydraulic fluid conductors must have sufficient cross-sectional areas to satisfy the flow rate requirements without producing excessive pressure drops. They must be strong enough to withstand the working pressure as well as the shock pressures and/or vibration. They should also have smooth interiors to reduce the friction and flow turbulence in the associated system. They must withstand high operating temperatures. They must also be compatible with the type of fluid used. Further, they must be supported by damped mountings to absorb both shock and vibration.
