ppt working principle of pulse tube refrigerator

Abstract

The working fluid for the pulse tube refrigerator is Helium, which is non-toxic to humans and harmless to the environment. The Pulse Tube Refrigeration unit offers a viable alternative to units that currently require CFC and HCFC working fluids. Pulse Tube Refrigerators can be operated over wide range of temperatures. These units can be used in numerous space and commercial applications, including food freezers freeze dryers. It can also be used to cool detectors and electronic devices ....etc

CEILING FAN OBJECTIVE : To study the working, construction And troubleshooting of Ceiling Fan
2. INTRODUCTION A ceiling fan is a device suspended from the ceiling of a room, which employs hub- mounted rotating paddles to circulate air. First electrically powered fan was invented in 1882 by Philip Diehl. Crompton Greaves Ltd is the leading manufacturer of fans.
3. PRINCIPLE If a current carrying conductor is placed in a magnetic field it experience a force and start to rotate. The direction of rotation can be found by Fleming s Left Hand R ....etc

principle of operation of induction generator ppt

An induction generator or asynchronous generator is a type of alternating current (AC) electrical generator that uses the principles of induction motors to produce power. Induction generators operate by mechanically turning their rotors faster than synchronous speed. A regular AC asynchronous motor usually can be used as a generator, without any internal modifications. Induction generators are useful in applications such as mini hydro power plants, wind turbines, or in reducing high-pressure ga ....etc

working principle of hydraulic excavator ppt

Excavators are heavy construction equipment consisting of a boom, dipper (or stick), bucket and cab on a rotating platform known as the house.The house sits atop an undercarriage with tracks or wheels. They are a natural progression from the steam shovels and often mistakenly called power shovels. All movement and functions of a hydraulic excavator are accomplished through the use of hydraulic fluid, with hydraulic cylinders and hydraulic motors.Due to the linear actuation of hydraulic cylinders, ....etc

Quadrotor



A quadrotor, also called a quadrotor helicopter or quadrocopter, is a multicopter that is lifted and propelled by only four rotors. Quadrotors are classified as rotorcraft, as opposed to fixed-wing aircraft, because their lift is derived from four rotors. Unlike most helicopters, quadrotors use fixed-pitch blades, whose rotor pitch does not vary as the blades rotate; control of vehicle motion is achieved by varying the relative speed of each rotor to change the thrust and torque ....etc
