Hydraulics Vs Pneumatic! and the winner is Hydro-pneumatic
The world has seen the continuous depletion of fossil fuels since ages. Present day scenario is turning into a threat to the energy sector. The developed countries of the world have adapted multiple techniques to reduce on the energy consumption through innovative advancements. Replacement of automobiles with electric vehicles, replacement of energy consuming tungsten bulbs with energy efficient LED devices, continuous upgrading of engines to save on fuel, solar operated appliances etc.
Among all the other industries of the world, manufacturing and construction industries are the major industries to consume energy and the players of these industries have been focusing on productivity since ages. Lately, some major players have shifted their focus to key factors such as Quality control, smooth production, Automation and also Industry 4.0. But, none so far have thought about a system that can reduce the energy consumption. So isn’t there a system in place that can reduce the energy consumption? Surely there is! The Hydro pneumatic system. Highly Energy efficient, quality resulting, minimum maintenance, Leak proof and noiseless solution for a specific pressing purpose that involve forming of metal components.
The simple fact behind Hydro pneumatic systems is “Why waste energy to do no work?”.
Yes, the pneumatic setup of the Hydro pneumatic cylinder does no heavy job, but simple movements with the air pressure. The pressing job is done by the oil that is pressurized by the Intensifier that again is air driven. Hence, the Hydro pneumatic system takes compressed air to drive the setup. When compared with Hydraulically driven systems, Hydro pneumatic consume very little power to operate. Moreover, only the controllers do. Wherein the hydraulic systems consume electricity in large scale to drive the power pack in every cycle that it performs.
Why are Hydro pneumatic systems better than Hydraulics? Need a demo? call us
- Medium of operation
Hydraulics are oil-driven. The energy transferred from the high-pressure pump pressurizes the oil and results in the movements of sliding members of the cylinder. Pneumohydraulic is a hybrid system of hydraulics and Pneumatic. They use both Air and Oil pressure to perform work. The swift movements of the members are air driven. The major work done such as the application of load is oil pressure driven.
- Power consumption
Hydraulic systems use 3 phase power supply in Indian manufacturing environment. Hydraulic power pack drives the system. The energy efficient hydro pneumatic systems operate with air pressure of 5 bar and a single phase power supply for the functioning of the controllers.
- Oil requirement
The Hydraulic systems use oil pressure to do the work, Hence require a large amount of oil for the operation. The periodic maintenance of the cylinder demands changes of oil on regular basis or a filtration process. The hydro pneumatic systems considerably reduce the oil requirement and Hence, cuts down the maintenance overheads.
Movement of the oil in the moving bodies of cylinder results in heat generation, Leakage and Noise in common. This results in frequent wear and tear of the cylinder walls due to contamination in the oil. Hydro pneumatic operate with Minimum oil quantity of oil through a reservoir that is in separation with the moving members of the press. Hence give a minor scope for maintenance. However, periodic maintenance definitely gives a longer life to the machine, be it Hydraulic or Hydro pneumatic
Hydraulics are used in some of the obvious places like Dump trucks, constructional equipment and other heavy equipment because they do the job right. But do small operations such as clinching, riveting, Bush pressing, bearing pressing other assembly related pressing jobs to require a Hydraulic system? Hydro pneumatic system does them right, precise and perfect.
