This equipment is designed for carrying out the experiment for balancing a rotation mass system. The apparatus consists of a stainless steel shaft fixed in a rectangular frame. A set of four blocks with a clamping arrangement is provided. For static balancing, each block is individually clamped on shaft and its relative weight is found out using cord and container system in terms of number of steel balls. For dynamic balancing, a moment polygon is drawn using relative weights and angular and axial position of blocks is determined. The block are clamped on shaft is rotated by a motor to check dynamic balance of the system. The system is provided with angular and longitudinal scales and is suspended with chains for dynamic balancing.
1. To balance the masses statically and dynamically of a single rotating mass system.
2. To observation of effect of unbalance in a rotating mass system.
Electricity 0.5 kW, 220 V, Single Phase
Technical Specification: -
1. Drive Motor -- FHP Motor, variable speed, with speed controller
2. Balancing Weight -- 4 Nos. of Stainless Steel with different sized eccentric Mass for varying unbalance
3. Rotating Shaft -- Material Stainless Steel
4. The whole Set-up is well designed and arranged in a good quality painted Structure
The unit consists of a base upon which the bearing holders and driving motor are bearing can be fitted in a holders to end conditions for test shafts, viz. Both end fixed and one end free, one end fixed. A Variac provided control of driving motor. The unit demonstrates the phenomenon of whirling of shafts with single rotor. As the test is destructive, after the test cannot be used, hence the unit only demonstrates the principle.
However, results obtained are closer to theory, as compared to those with bare shafts. Also, It can be demonstrated that, after passing whirling speed, shaft again starts running true.
The apparatus consists of a plain steel shaft excavated in a bearing and directly driven by a FHP Motor. The bearing is freely supported on the shaft and sealed at the motor end. The speed of the motor is controlled by the speed control unit. One compound pressure gauge is mounted on bearing to measure the pressure at different position around the circumference. Bearing is free to rotate and can be adjusted at any position of circular scale. The bearing can be loaded by attaching weights to the arm supported beneath it.
SCOPE OF DELIVERY:
DESCRIPTION:Gear Train is any combination of gear wheels by which motion is transmitted from one shaft to another shaft. In epicyclical gear trains, the axes of shafts on which the gears are mounted may move relative to a fixed axis. It is a motorized unit consisting of a SUN gear mounted on input shaft. Planet gears meshes with the annular gear. These planet gears are mounted on a common arm to which output shaft is fitted. Loading arrangement is provided for loading the system and to measure holding torque
The set-up is designed to study Coriolli's Component of Acceleration of a slider crank mechanism. Here the mechanical slider system is replaced by a continuous stream of water flowing through a steady rotating pair of tubes. These tubes can be rotated at various speeds by using a swinging field motor which also acts as dynamometer. A Perspex window on top of the tank gives clear view of the process and prevents splash of the water over the side of the tank. The dynamometer continuously measures torque applied to the rotating tubes. The equipments is self contained, water re-circulating, provided with its own speed control unit and water circulating pump.
SCOPE OF DELIVERY:
Single Cylinder Four Stroke VCR Diesel With EGR
The setup consists of single cylinder, four stroke, VCR (Variable Compression Ratio) Electric start Diesel engine connected to eddy current type dynamometer for loading. The compression ratio can be changed without stopping the engine and without altering the combustion chamber geometry by specially designed tilting cylinder block arrangement. Setup is provided with necessary instruments for combustion pressure and crank-angle measurements. These signals are interfaced to computer through engine indicator for PV diagrams. Provision is also made for interfacing airflow, fuel flow, temperatures and load measurement.
The set up has stand-alone panel box consisting of air box, two fuel tanks for blend test, manometer, fuel measuring unit, transmitters for air and fuel flow measurements, process indicator and engine indicator.
Rotameters are provided for cooling water and calorimeter water flow measurement.
The setup enables study of VCR engine performance with EGR for brake power, indicated power, frictional power, BMEP, IMEP, brake thermal efficiency, indicated thermal efficiency, Mechanical efficiency, volumetric efficiency, specific fuel consumption, A/F ratio and heat balance. Labview based Engine Performance Analysis software package is provided for on line performance evaluation.
A computerized Diesel injection pressure measurement is optionally provided
