Rotodynamic compressors Manufacture in Dubai

These Rotodynamic compressors have rotating equipment parts imparting momentum to the gas particles which is later converted to pressure. For the rotodynamic compressors type of compressors the flow is continuous. These compressors are often smaller in size and produce much less vibration than the positive displacement compressors.

Rotodynamic compressors can be axial flow, centrifugal flow, or the intermediate mixed/diagonal flow types. A rotodynamic compressors has one or more rotating assemblies, handles large volumes, and can be electrically, steam or gas driven. Rotodynamic compressors often need to have valve and other systems to control against “surge,” a sudden flow reversal which can cause destructive vibration.

A rotodynamic compressors is a mechanical device that increases the pressure of a gas by reducing its volume. An rotodynamic compressors is a specific type of gas compressor.
Compressors are similar to pumps: both increase the pressure on a fluid and both can transport the fluid through a pipe. As gases are compressible, the compressor also reduces the volume of a gas. Liquids are relatively incompressible; while some can be compressed, the main action of a pump is to pressurize and transport liquids.

Rotodynamic compressors consist of a rotor with a number of blades inserted in radial slots in the rotor. The rotor is mounted offset in a larger housing that is either circular or a more complex shape. As the rotor turns, blades slide in and out of the slots keeping contact with the outer wall of the housing.Thus, a series of increasing and decreasing volumes is created by the rotating blades. Rotary Vane compressors are, with piston compressors one of the oldest of compressor technologies.
With suitable port connections, the devices may be either a compressor or a vacuum pump. They can be either stationary or portable, can be single or multi-staged, and can be driven by electric motors or internal combustion engines. Dry vane machines are used at relatively low pressures (e.g., 2 bar or 200 kPa or 29 psi) for bulk material movement while oil-injected machines have the necessary volumetric efficiency to achieve pressures up to about 13 bar (1,300 kPa; 190 psi) in a single stage. A rotary vane compressor is well suited to electric motor drive and is significantly quieter in operation than the equivalent piston compressor.
Rotary vane compressors can have mechanical efficiencies of about 90%.
