Centrifugal Compressor

A centrifugal compressor is a type of dynamic compressor used for gas compression. It operates by imparting kinetic energy to the gas through a rotating impeller, converting it into pressure energy in a diffuser and volute. It is widely used for compressing gases in industries due to its ability to handle large volumes at relatively high pressures. Working Principle of a Centrifugal Compressor The centrifugal compressor operates based on dynamic compression : 1. Gas Inlet : • Gas enters the compressor axially through the suction port and is directed to the impeller. 2. Kinetic Energy Addition : • The rotating impeller imparts kinetic energy to the gas by accelerating it outward through centrifugal force. 3. Pressure Build-Up : • The high-velocity gas enters the diffuser , where its velocity decreases, and the kinetic energy is converted into pressure energy. 4. Gas Discharge : • The gas is collected and further pressurized in the volute before being discharged at the des...

Screw Compressor

A screw compressor is a type of rotary compressor that operates based on the positive displacement principle . Its working mechanism involves two intermeshing helical rotors (commonly referred to as male and female rotors) that compress air or gas by reducing the volume of the compression chamber. Working Principle of a Screw Compressor: 1. Suction : • Air or gas enters the compressor through an inlet port. • The rotors start to rotate, creating a space for the air to enter between the rotor lobes. 2. Compression : • As the rotors rotate, the air is trapped between the male and female rotor lobes. • The shape of the rotors gradually decreases the volume of the air or gas trapped in the compression chamber. • This reduction in volume compresses the air, increasing its pressure. 3. Discharge : • The compressed air or gas is pushed towards the discharge port as the rotors continue to rotate. • The compressed air exits the compressor at the required pressure. Key Features: •...

Types of Pumps & Their Functionality

Pumps are mechanical devices used to move fluids from one location to another. They come in various types, each designed for specific applications and functionalities. Here’s an overview: 1. Centrifugal Pump Functionality: • Uses a rotating impeller to impart kinetic energy to the fluid. • Converts this kinetic energy into pressure energy to move the fluid. Applications: • Water supply, agriculture, cooling systems, and large industrial setups. 2. Positive Displacement Pump Functionality: • Moves a fixed volume of fluid through a cyclic process, irrespective of pressure. • Provides consistent flow at varying pressures. Subtypes: 1. Gear Pump: Uses meshing gears to transport fluids. 2. Diaphragm Pump: Employs a flexible diaphragm to move fluids. 3. Piston Pump: Uses a piston mechanism to displace fluid. Applications: • Oil transfer, viscous fluids, high-pressure applications, and hydraulic systems. 3. Submersible Pump Functionality: • Fully submerged in the fluid, pumpin...

Commissioning of Centrifugal pumps

Commissioning of centrifugal pumps involves a series of activities to ensure that the pumps are correctly installed, tested, and operate as intended before being put into service. These activities focus on verifying the pump’s performance, confirming the integrity of the installation, and ensuring safety and efficiency. Below are the key commissioning activities for centrifugal pumps: 1. Pre-Commissioning Activities • Inspection and Verification : • Visual Inspection : Check the centrifugal pump for any shipping damage, ensure all components are installed correctly, and verify that the pump and motor match the specifications and drawings. • Foundation Check : Verify that the pump and motor base are securely mounted and that the foundation meets the design requirements. • Alignment : Ensure the pump and motor shafts are aligned properly (couplings should be properly connected and aligned to prevent vibration). • Piping Inspection : Verify that all piping (suction, discharge, ...
