Air hydro booster, also called air hydraulic pressure booster or pressure intensifier is the ancillary device that is designed to amplify the hydraulic pressure with compressed air. High hydraulic pressure is vital for cylinders that require small to medium amounts of oil with high pressure when operating.
Air hydro boosters consist of a hydraulic cylinder that has a small diameter. The hydraulic cylinder (or ram) is driven by an air cylinder that has a larger diameter. The air hydro booster can consistently provide high-pressure fluid (usually oil) toward the small hydraulic cylinder. The air cylinder which consists of a solid end and mediates plates and an enhanced epoxy outer can house the fluids. On the other hand, the piston inside the steel hydraulic cylinder is immersed in the fluid reservoir. The feature of the double piston provides excellent fluid capacity on each booster actuation.
From the air hydro boosters, any system that is equipped with airlines is capable of receiving hydraulic power. Air hydro booster is a cost-effective and efficient method to power a single-acting system. It can be mounted vertically or horizontally depending on the use. While mounted vertically, the discharging unit of the oil should be adjusted to discharge upward for consistent operation. Air hydro boosters are not suitable for single-acting disconnected systems; also, one booster is only capable of working with a single-acting system.
The air hydraulic booster system consists of the booster cylinder, the working cylinder with the rod that has a double-ended, hydraulic/pneumatic hose, hydraulic flow control valve that is responsible for regulating the speed of the cylinders, and fittings.
Air hydro boosters are used to convert and amplify the working pressure in order to perform operations that require higher pressure. The booster usually operates with the hydraulic cylinder but does not necessarily require the hydraulic power unit. Both the body and the inner design of air hydro booster are similar to a cylinder. The difference lies in the rod end of the piston which does not stretch outside. The rod plays a role as the ram for hydraulic fluids. When the hydraulic valves are powered, workshop air that comes in the booster will extend the ram, conveying the oil into the cylinder and extending the rod down. As the valve de-energizes, the ram then retracts back to the original position. The high hydraulic pressure will be kept within the whole stroke instead of a small part.
Air hydro booster functions like a transformer and pulley system, which converts the ratio of pressure from input to output without amplifying powers. In most plants, the low pressure (typically 80 to 100 PSI) will be converted in a connected, large booster cylinder into much higher pressure on the output side. Total power in the system stays the same, and the high pressure produces from much smaller units as the workshop air operates against a large area piston. When choosing a proper air hydro booster, the ratio of input and output pressure and the volume of output that fits the booster cylinder are both vital. The ratios provide from standard air hydraulic boosters are ranged from 2:1 to 36:1.
Although an air hydraulic booster can never replace a pump-cylinder method, in certain types of applications, it is still an ideal choice for machine tool builders that don’t have space and require an entire hydraulic power unit. Air hydro boosters are more cost-efficient and reduce many troublesome particular requirements and disadvantages within hydraulic power units.
When it comes to the benefits of air hydro boosters, for starters, they eliminate the need for noisy motors and create much less noise in the operation. Secondly, they remove the need for hydraulic tanks and pumps which might be leaky and require more energy and maintenance. Also, there are no heat issues happening with coolers in hydraulic power systems.
When sitting idle, the air hydro booster does not consume any air. The feature and simpler construction make the boosters popular for less maintenance due to less moving parts and less downtime and more space for other equipment that are intended to connect with the boosters.
