DOM MANUAL / B-TECH / MECHANICAL / KUK - TO PERFORM EXPERIMENT ON WATT AND PORTER GOVERNORS TO PREPARE PERFORMANCE CHARACTERISTIC CURVES, AND TO FIND STABILITY & SENSITIVITY.
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 (WATT GOVERNOR) b) LOADED TYPE c) DEAD WEIGHT GOVERN
