A hydraulic intensifier is used to increase the pressure of a liquid (water), which is at low pressure and large volume to a higher pressure and lower volume.It increases the pressure in a hydraulic circuit to a higher value than the pressure provided by the pump. These older hydraulic machines required hydraulic liquids which are at higher…
Condenser:- A condenser is a heat exchanger used to condense a gaseous substance into a liquid state through cooling.It is a component of a thermal power plant and is also used in a refrigeration system.It uses water as a cooling medium. A condenser is used for taking the latent heat of the fluid and converting…
Shot blasting is one of the methods of surface treatment in which irregularities on the metal’s surface are removed by the use of particulate grains propelled at high velocity.Shot blasting is different from sand blasting because shot blasting uses a centrifugal wheel, whereas in the sand blasting method, compressed air is used to deliver its…
Soldering:- Soldering is the process of joining two similar or dissimilar metals by means of filler material ( lead, tin, alloy ).The melting point will be less than 450°C of the filler material.The melting point of filler material is always less than the melting point of the parent metal, whether it is brazing or soldering.Flux…
When the axes of the first gear (i.e., first driver ) and last gear (i.e., last driven or follower ) are the same, the gear train is called a reverted gear train. Reverted gear trains are used in automotive transmissions, lathe back gears, industrial speed reducers, and in clocks ( where the minute and hour…
Velocity ratio is the ratio of the distance moved by the effort to the distance moved by the load in a machine.Or,Velocity ratio can be defined as the ratio of the velocity of the effort to the velocity of the load in a machine. Velocity ratio is a dimensionless constant. We know that, There are…
Electrolux Refrigeration is also known as Domestic Electrolux refrigeration or sometimes known as Three fluid Refrigeration as it uses three fluids for the cooling process which are ammonia, water and hydrogen. Ammonia works as a coolant in this refrigeration system.Water is used as a solvent. Ammonia is dissolved in the water.Hydrogen gas is used to…
Snap gauge is one of the types of go-nogo gauges.It is a gauging tool which means it assesses whether part of the cylindrical or non-cylindrical shape meets its dimensional specification without actually providing a measurement of the actual value of the dimension.The snap gauge is used to measure the outer diameter of the jobs of shapes like…
Dual Cycle which is also known as mixed or limited-pressure cycle, is a thermodynamic model for internal combustion engines that blend the Otto (spark-ignition) and Diesel (compression-ignition) cycles. The other names for Dual Cycle include Seiliger Cycle Or Sabathe Cycle.Dual Cycle was first introduced by an engineer named Gustav Trinkler. In this cycle, part of…
Simple gear train is a gear combination of two or more gears in which only one gear is present in each shaft.Simple gear train can consist of two, three, four or more gears with one gear in each shaft.Every simple gear train has a driver gear and a driven gear. The driver gear is connected…
