This document summarizes a presentation given at an AIChE conference that proposed a new definition of impeller efficiency based on the kinetic energy imparted to the fluid rather than traditional definitions. It discussed two common efficiency definitions and introduced a new "kinetic energy number" metric. The presentation used computational fluid dynamics simulations to compare the efficiency of different impeller types in an experimental tank, finding that a pitched blade turbine imparted 12% more kinetic energy while requiring 15% less power than a hydrofoil impeller, demonstrating its higher efficiency for that system based on the first law of thermodynamics. However, the hydrofoil produced a more homogeneous flow distribution.

Pump survey & line bearing

This document discusses different types of pumps and their components, including centrifugal pumps, gear pumps, screw pumps, and mono pumps. It also describes pump bearings, noting that line bearings are used to keep the pump shaft steady and prevent damage. Common materials for line bearings include teflon, elastomers, polyester, carbon and simsite. The document outlines the characteristics of line bearings such as being self-lubricating and withstanding high temperatures and loads, as well as some disadvantages like being prone to cracking and having a high cost.

1.3 bearing designation system

Chetan vadodariya

Bearing designations provide information about the bearing type, size, and any supplementary details. The basic designation indicates the product type, standard design, and size. Supplementary designations specify alternative designs, bearing components, and special types. Designations are broken into categories including internal design, external design, cage design, and performance enhancements. Together, the basic and supplementary designations precisely identify bearing characteristics.

KML Bearing

The document discusses a new stainless steel bearing housing and sealing system called the KML Durapro. It has increased load capacity and protection for bearings. The system uses a stainless steel housing that locks a thermoplastic or spring-loaded face cap in place. It also uses KML Poly-Guard multi-stage sealing. This provides complete enclosure and eliminates areas for debris. The housing is suitable for applications in food processing, chemical plants, and other industries dealing with moisture and corrosion. It is available in various sizes and styles to suit different bearing needs.

Impeller – the soul of the centrifugal pump

Rolling element bearings transmit loads through rolling contact and provide lower coefficients of friction than sliding contact bearings. They are composed of an inner race, outer race, rolling elements (balls or rollers), and a cage. Ball bearings are further classified as deep groove, angular contact, or filled notch types. Roller bearings use cylindrical or tapered rollers and have higher load capacity than ball bearings. Bearing life is rated based on the number of revolutions or hours it can operate before spalling or pitting failure occurs, with an L10 life rating meaning 10% of tested bearings will fail by that point.

This document discusses different types of bearings. It begins by defining a bearing as a device that allows constrained relative motion between two parts, typically rotation or linear movement. It then classifies bearings based on the motions they allow and their principle of operation. The document goes on to describe various types of bearings in detail, including ball bearings, roller bearings, thrust bearings, tapered roller bearings, and cylindrical roller bearings. It provides information on the characteristics, advantages, applications, and physical features of each bearing type.

PUMPS

Tamanash Pramanick

Pumps are devices that use mechanical energy to increase the velocity, pressure, or elevation of liquids and gases. There are two main types of pumps: positive displacement pumps and dynamic pumps. Positive displacement pumps apply direct pressure on a liquid using a reciprocating piston or rotating components. Dynamic pumps use centrifugal force to generate high rotational velocities and convert the kinetic energy of liquids into pressure energy. Common positive displacement pump types include piston pumps, plunger pumps, and diaphragm pumps. Common dynamic pump types include centrifugal pumps which contain an impeller and casing. Proper consideration of factors like net positive suction head are important for pump selection and operation.

This document discusses different types of pumps, including their classifications, characteristics, applications, and performance. It describes hydrodynamic/non-positive displacement pumps, which use flow to transfer fluid at relatively low pressure and are generally used for low pressure, high volume applications. It also describes hydrostatic/positive displacement pumps, which have close-fitting components and can create high pressures, making them self-priming. Specific positive displacement pump types like gear, vane, piston and centrifugal pumps are examined in terms of their applications and operating principles. Pump efficiencies including volumetric, mechanical and overall efficiency are also covered.
