The bridge rectifier circuit gives an output similar to that of a full wave rectifier. However, it consists of four diodes arranged in the form of a bridge as shown in Fig. 1. The diodes usually employed are the solid state diodes though vacuum tubes can also be used.
What is Plasma Arc Machining (PAM)? Process, Diagram, Advantages & Applications
Figure 1: Plasma Arc Machining (PAM).
Working Principle of Plasma Arc Machining (PAM)
The gas molecules at room temperature consists of two or more atoms. When the temperature of gas molecules is heated to 2000°C, the molecules dissociated out as atoms. If the temperature is further increased to about 3000°C, the atoms dissociate their electrons and the gas becomes ionized (ions and electrons).
What is Chemical Machining? Process, Diagram, Advantages & Applications
Figure 1: Chemical Machining.
Working Principle of Chemical Machining
Chemical machining is a process used for removing the material by dipping it into a chemical solution which dissolves all the material of the workpiece. Depending upon the requirement the material is removed from the workpiece portions which are uncovered with the masks.
What is Electrical Discharge Machining (EDM)? Process, Diagram, Advantages & Applications
Figure 1: Electrical Discharge Machining
Electrical discharge machining is versatile among all electrical machining methods. This process is also named “spark erosion machining” or “spark over initiated discharge machining”, as the removal of metal occurs due to erosion caused by the electric spark.
What is Electrochemical Grinding (ECG)? Process, Diagram, Advantages & Applications
Figure 1: Electrochemical Grinding (ECG)
Depending upon the improvement of electrochemical machining process, the electrolytic process is developed. In the electrochemical grinding process, the removal of material takes place by electrochemical deposition (90%) as well as material abrasion (10%).
What is Water Jet Machining? Process, Diagram, Advantages & Applications
Figure 1: Water Jet Machining.
The above figure 1 shows the setup of equipment for water jet machining. It consists of a hydraulic pump which is driven by an electric motor of about 30 kW. The pump increases the oil pressure upto 117 bar so that it can operate reciprocating plunger pump also known as intensifier. The intensifier plays a significant role in the process. The water enters the intensifier at 4 bar and leaves with high pressure, about 3800 bar. Also, this device helps to maintain continuous flow of high pressure water. This water is then allowed to flow in an accumulator in order to maintain a uniform discharge pressure and velocity of water.
What is Heat Pipe? Working, Diagram, Types & Applications
A heat pipe is a heat transfer device in which the transfer of heat between the hot and cold regions takes place in vaporised about condensed forms of working fluid. The condensed fluid in a heat pipe, flows from cold to hot region due to capillary action.
Figure 1: Heat Pipe.
What is Regenerative Heat Exchanger? Working, Diagram & Types
A regenerative heat exchanger, most commonly called as a regenerator or capacitive heat exchanger, is a kind of heat exchanger in which the heat from hot fluid is stored in a thermal storage medium when it is passed over it. The cold fluid is allowed to flow through this medium where the heat is transferred to this fluid. Thus heat transfer in regenerators occurs intermittently.
What is Water Cooler? Working, Diagram & Types
Function: Water coolers are used to give cold water having temperature, around 8°C to 16°C for drinking purpose.
Types of Water Cooler
The three types of water coolers are
- Storage type
- Instantaneous type
- Bottle type.
