Reliability Issues – Centrifugal Slurry Pumps Introduction Pumps were probably the first machine ever developed‚ and are now the second most common machine in use around the world‚ out-numbered only by the electric motor. The very earliest type of pump is now known as a water wheel‚ Persian wheel or “noria”‚ consisting of a wheel of buckets that rotates to pick up water from a stream and dump it into a trough. Another early pump was the “Archimedean screw”‚ similar to the modern screw conveyor

A turbine is a rotary mechanical device that extracts energy from a fluid flow and converts it into useful work. 1.Steam Turbines 2. Wind Turbines 3. Water Turbines 4. Gas Turbines It is a device that extracts thermal energy from pressurized steam and uses it to do mechanical work on a rotating output shaft. The steam turbine is a form of heat engine that derives much of its improvement in thermodynamic efficiency through the use of multiple stages in the expansion of the steam

Compressors are similar to pump‚ both increase the pressure on a fluid and both can transport 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. Types of compressors The main types of compressors are shown below: Compressor types Positive displacement Dynamic 1. Reciprocating. 2. Rotary 1.Centrifugal. 2. Axial
