Air lift pump is a device that is used to lift water from a well or a sump with the use of compressed air. This pump is also called a mammoth pump.Airlift pumps have been used since the beginning of the 20th century.The first airlift pump was invented by the German Engineer Carl Emanuel Loscher in…
Vane Compressor is also known as Rotary Vane Compressor or Sliding Vane compressor.Vane Compressor was invented by Charles C. Barnes of Canada. He patented it on 16 June 1874.Vane Compressor are one of the most widely used products in today’s world. They serve a wide range of industries.Vane Compressor used centrifugal motion to generate compressed air. Vane compressors…
Solex carburetor is a modification of simple carburetor. The simple carburetor works well in normal working conditions but it does not work well in conditions like winter and summer season, idle condition and high acceleration condition. In these conditions, Solex carburetor works well.The main work of carburetor is to create air-fuel mixture in the right…
Capstan Lathe is the modified form of Engine Lathe and Center Lathe in which the tailstock is replaced by a hexagonal turret tool head. It was first developed by Pratt and Whitney in America in 1860. It was needed to develop capstan lathe because in center lathe there was only one tool post and only…
Today we will discuss types of welding flames.There are mainly three types of flames used in welding, they are:- 1) Natural Flame or Neutral Flame:-It is called natural flame because when we do welding with this flame no chemical reaction takes place. Also, this flame produces very little smoke.Neutral flame has equal oxygen and gas…
Normalizing is the process of heating of metal that alters the properties of metal like tensile strength, ductility and also refines the grain structure.It is a type of heat treatment applicable to ferrous metals only.In the normalizing process, the material is heated to elevated temperature and after that, it is cool back by placing it…
Cutting tool materials are the materials of the cutting tool present in the machines which are used in different machining processes like turning, shaping, slotting, etc. Here we are not talking materials of cutting tools like knives. Properties of cutting tool material: 1) Hot or Red Hotness:It is the ability of the cutting tools to…
Gas Welding is the process where two or more parts of the metal are joined or united by melting them using the heat transmitted by flame produced by the reaction of oxygen and fuel gas.Gas Welding is also called oxy-fuel welding. It is called oxy-fuel welding because in this process oxygen is used with burning…
Cutting fluid is a fluid that is mainly used to remove the heat produced during the metal cutting and other machining processes. It is also used as a lubricant in some cases.They are also used for improving the cutting condition and also the tool life.Cutting Fluids reduce the friction between the tool and the chip…
Ericsson Cycle is a thermodynamic cycle which consists of constant pressure heat addition and rejection.The Ericsson Cycle is named after its Swedish inventor John Ericsson. Many heat engines based on various thermodynamic cycles were but by him.Ericsson was also responsible for the early use of the screw propellor for ship propulsion built in 1842.The first…
