CENTRIFUGAL PUMP TEST RIG INTRODUCTION TO CENTRIFUGAL PUMPS The Hydraulic Machines which converts the Mechanical energy into Hydraulic energy are called Pumps. The Hydraulic energy is in the form of Pressure energy. If the mechanical energy is converted into Pressure energy by means of centrifugal force acting on the Fluid, the Hydraulic machines is called Centrifugal Pumps. The centrifugal fan with consists of a blower driven by FHP Motor with a series of curved redial vanes. Air is drowning in near the hub, called the blower eye, and is whirled round at high speed by the vanes on the blower as the blower rotates at high rotational speed. The static pressure of the air increases from the eye of the blower to the tip of the blower in order to provide the centrifugal force on the air. As the air leaves the blower tip it is passed through diffuser passage which converted most of the kinetic energy of the air into an increase in enthalpy and hence the pre...

AIM:-TO PERFORM EXPERIMENT ON WATT AND PORTER GOVERNORS TO PREPARE PERFORMANCE CHARACTERISTIC CURVES, AND TO FIND STABILITY & SENSITIVITY. APPARATUS USED: -  WATT AND PORTER GOVERNORS. INTRODUCTION & THEORY: -  THE FUNCTION OF A GOVERNOR IS TO REGULATE THE MEAN SPEED OF AN ENGINE, WHEN THERE ARE VARIATIONS IN THE LOAD E.G. WHEN THE LOAD ON AN ENGINE INCREASES, ITS SPEED DECREASES, THEREFORE IT BECOMES NECESSARY TO INCREASE THE SUPPLY OF WORKING FLUID. WHEN THE LOAD ON THE ENGINE DECREASES, ITS SPEED INCREASES AND THUS LESS WORKING FLUID IS REQUIRED. THE GOVERNOR AUTOMATICALLY CONTROLS THE SUPPLY OF WORKING FLUID TO THE ENGINE WITH THE VARYING LOAD CONDITIONS AND KEEPS THE MEAN SPEED WITHIN CERTAIN LIMITS. THE GOVERNORS MAY, BROADLY, BE CLASSIFIED AS 1.      CENTRIFUGAL GOVERNOR 2.      INERTIA GOVERNOR THE CENTRIFUGAL GOVERNORS MAY FURTHER BE CLASSIFIED AS FOLLOWS: a)     PENDULUM TYPE (...
