Fluid power provides the muscle for various work operations in stationary and mobile applications. As we can see, the use of fluid power is widespread in many applications. However, many 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 systematic training in fluid power. We offer hydraulic and pneumatic courses to meet the contemporary needs of the industry and educational institutes. Further, the training centre provides blogs covering technical information on fluid power. We hope these blogs will benefit especially new entrants in the field.
Snippet #1 Hydraulic Power Transmission System
Pure hydraulic systems can handle a vast amount of force with compact components. They offer good controllability and resistance to shock loads. 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 also be strong enough to withstand the working pressure, shock pressures, and/or vibration. They should also have smooth interiors to reduce friction and flow turbulence in the associated system. They must also 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.
