Hydraulic intensifiers are designed for delivering high amount of pressure from a low-pressure hydraulic power source. The hydraulic intensifier uses less energy while input pressure and converts the fluid energies to higher output pressures. There is no change in the laws of thermodynamics when performing this action. Actually, an intensifier is already equipped with a hydraulic architecture.
Hydraulic intensifier is also called as hydraulic booster. Their operation is powered by a pump that works from a hydraulic power source that is at low-pressure. The pump operation is set at a certain pressure and from this the intensifier generates an increased output pressure. Their use is commonly seen in hydraulic power pack.
The intensifiers are designed in a compact manner and can be installed easily. Offered as in-line models that fit the standard pipe clamps used in the industry, as CETOP models, flange-on models and as cartridge type intensifiers. Though they have compact design, all the needed high-pressure check valves are integrated.
There are different hydraulic intensifier models that can be used for flows that start at 0.3 gpm and up to 21 gpm. In case it is built into a bypass, they can be used in very high flow systems. They are commonly used in systems for generating end pressures between 1,000 and 7,300 psi. There are some models that have the ability to increase the end pressures between 20,000 and 60,000 psi.
How Do Intensifiers Simplify System Design?
There is a low system inlet pressure that flows. The powered pump remains active and the differential piston design performs its duties as guided by it. This seems to be a complicated configuration. But the truth is that the hydraulic intensifiers are loaded within the self-contained cylinders that can be installed on existing or new mobile excavators. The compact cylinder’s circuit layout recommends in-line usage. Hence, it requires minimum installation skills. Additionally, this design is logically expanded and so, during the installation phase, it should have standard pipe clamps and fittings.
Hydraulic Intensifiers as Flexible Fluid Force Enhancers
In case a particular circuit-enhancing application doesn’t accept the in-line models, these pressure boosting parts can be used in other common forms such as CETOP (European fluid transmission committee) compatible models and flange-on variants. Also, to make the system more simple for dividing it into compartments and creating a self-contained expanded pressure architecture. Intensifiers can be commonly found installed on excavators, mini diggers that have less ability for fluid actuation assemblies and complex valves. It operates parallel to a Hydraulic Power Unit (HPU) or a capable fluid power pack and ensures the pressure generated is low throughout the hydraulic network as well as a high-pressure throughput is created right wherever required.
Hydraulic intensifiers help in boosting the circuit pressure but that it occurs in the system where required and not throughout the complete system. Therefore, the input pressure is low and there is less stress on system. Since these are installed as a single force developing package, they improve the design of a hydraulic system as well as upgrade the system’s performance.
