♦ Compressors are used to compress gases. In fact, compressors are devices that, with a lot of mechanical energy, slowly suck the fluid into and then compress it.

As a result of this operation, the gas temperature that is compressed also increases. Typically, the exhaust gas from the compressors passes through a cooling system to return the gas temperature back to normal.

♦ Turbo pumps are the most important category of dynamic pumps. Turbo pumps are machines that increase energy potential and kinetics of fluid through mechanical energy and generate spin-off hydraulic power generation.

In these pumps, the impeller is a mechanical energy-driven drive to the fluid. Due to the progress made in the technology of making these pumps, their application in the industry has become so commonplace that it often replaces reciprocally pumped pumps.
Sample Description

Types of Turbo Compressors


Compressors have different types. Various categories categorize compressors based on various features.
In one of the most commonly used categories, compressors are divided into two groups based on how they transfer energy from the compressor to the fluid:
Dynamic compressors: In these compressors, the energy transfer to the fluid is constant. Types of dynamic compressors are:
♦ Radial flow (Centrifugal)
♦ Axial current
Dynamic compressors are used at low-pressure and higher-pressure pumps.
Positive displacement compressors: In these compressors, energy transfer to the fluid is carried out alternately or periodically. Types of positive-displacement compressors are:
♦ Reciprocating
♦ Rotary
The compressor power density is higher than that of the dynamics. Of course, the compressor's discharge rate is far less than that of the dynamics.

Types of turbopumps


Turbo pumps can be divided into three categories according to the type of fluid motion inside:
♦ Radial pumps (full centrifuge): In these pumps, the fluid moves into the butterfly in the direction of the axis and is pulled out of the impeller in the direction perpendicular to the axis. The use of these pumps is low flow head and high head.
♦ Mixing pumps (semi-centrifuge): In these pumps, the fluid moves in the direction of the axis to the butterfly and leaves it diagonally from the axis. These pumps are in the middle and middle run.
♦ Axial pumps: In these pumps, the fluid moves in the direction of the axis to the butterfly and extends along it. The use of these pumps is high in low flow and low head.
Sample Description

 

The main purpose of this controller design was to replace the old I and II SpeedTronic systems. But it is clear that considering the same structure of gas turbines, it is possible to customize it and replace other controllers.


This system has the ability to control steady-state turbines (for launching synchronous generators) as well as variable ranges (for launching pumps, etc.). It is also possible to use the Isochronous and Droop modes for this controller. The temperature control section has the Base, Peak and Peak reserves modes.

 

This control system is designed for installation on gas turbines. The system has tried to use the latest technology of existing controllers. The selection of hardware, inventory, selected standards, traditionality in the Iranian industry and the frequency of services have been considered.
The entire control system is completely redundant and the protection sections are designed as fail safe. This system has local monitoring and remote control for the central steering room. Also, engineering and maintenance systems are also foreseen. All events are tagged in this system and can be retrieved if needed.

The overall structure of the controller is based on the Siemens PCS7 Family (SIEMENS) family. From the indicators of this design
The following can be noted:

    ♦ Use DCS structure
    
The main controller of the 400 family
    
Very fast auxiliary controller for controlling the governor's signals
    
The completely redundant structure of the H family
    
Fail safe design for protection segments up to SIL3 level according to IEC61508
