The system has few, if any, moving parts, and is also inefficient, so it is used where the kinetic or potential energy of water is cheaply available.
The advantage of a hydraulic compressor of the second type is the ability to perform isothermal compression without any moving parts, making it relatively reliable and having low maintenance costs.
The mixture enters the stilling chamber, which is designed to reduce flow velocity, allowing the air bubbles to separate from the water by buoyancy.
[2] The main issue with these compressors is the development of the scale and dimensions of the chamber (compressed air storage).
[4] By optimizing utilization or preventing leakage, companies can increase their profit margins.
A pipe structure without sharp corners or dead-heads can help maintain pressure and an efficient passage for compressed air.
Aluminum, for example, has a lower weight and corrosion resistance than the more traditional material, steel.
[4] Because it is much lighter than steel, aluminum pipes allow welders and technicians to manufacture and install them easier.
That would cause more pressure energy to be converted to heat or vibration, thereby decreasing the compressor's lifespan[5] To calculate the compressed airflow power, the equation
This can be done by applying the energy conservation equation for an isothermal flow (assuming water and air have the same pressure and velocity):
This flow can be calculated only at specific parts of the hydraulic pump, as various configurations can be implemented.
The equation calculates the efficiency of the pump head or driver, which can be graphed with electrical power consumed to compare hydraulic systems.
