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...

TURRET LATHE TURRET LATHE IS A FORM OF METALWORKING LATHE THAT IS USED FOR REPETITIVE PRODUCTION OF DUPLICATE PARTS (WHICH BY THE NATURE OF THEIR CUTTING PROCESS ARE USUALLY INTERCHANGEABLE). IT EVOLVED FROM EARLIER LATHES WITH THE ADDITION OF THE TURRET, WHICH IS AN INDEXABLE TOOL HOLDER THAT ALLOWS MULTIPLE CUTTING OPERATIONS TO BE PERFORMED, EACH WITH A DIFFERENT CUTTING TOOL, IN EASY, RAPID SUCCESSION, WITH NO NEED FOR THE OPERATOR TO PERFORM SETUP TASKS IN BETWEEN (SUCH AS INSTALLING OR UNINSTALLING TOOLS) NOR TO CONTROL THE TOOL PATH. (THE LATTER IS DUE TO THE TOOL PATH'S BEING CONTROLLED BY THE MACHINE, EITHER IN JIG-LIKE FASHION [VIA THE MECHANICAL LIMITS PLACED ON IT BY THE TURRET'S SLIDE AND STOPS] OR VIA IT-DIRECTED SERVOMECHANISMS TYPES OF TURRET LATHES THE ARCHETYPICAL TURRET LATHE, AND THE FIRST IN ORDER OF HISTORICAL APPEARANCE, IS THE HORIZONTAL-BED, MANUAL TURRET LATHE. IN MACHINE-SHOP JARGON, THE TERM TURRET LATH...
