Slip Creep Measurement Apparatus

The apparatus consists of a variable speed D.C. Motor, Driving pulley and Driven pulley of equal diameter. The pulleys are mounted on input shaft (Motor shaft) and output shaft. The driven pulley can slide on the base with bearing block to change initial tension in belt. Brake drum is mounted on output shaft helps to measure power output. The motor speed is varied by dimmerstat. A two channel RPM Indicator is provided to measure speeds of driven and driving pullies respectively.

Specifications:

1.D.C. Motor – 1 HP, 1500 RPM, variable speed. 2.Driving & Driven puilies of equal diameters. 3.Brake drum along with spring balance. 4.Fiat Belt of fixed length of following materials – (i)Fabric Belt (ii)Canvas Belt. (iii)Rubber Belt. 5.Belt tightening arrangement. 6.Speed Controller unit. 7.Two Channel digital RPM Indicator. 8.Stroboscope.

Experimentation –

1. To measure co-efficient of friction between pulley material and different belt materials. 2. To measure power transmitted with varied belt tensions and plotting graph of (T1 – T2).Tension Characteristics. 3. To measure percentage slip at fixed belt tension by varying load on brake drum and plot graph of (T1-T2) Vs.percentage slip.i.e. Slip Characteristics. Finding a creep zone from graph. 4. To measure belt slip speed and observe the limiting value float at constant speed when the slip just starts.

Service Required:

1.230 V.A.C. stabilized power supply 2.Space -. 1.5m x 1.5 m.

Thermal Conductivity Of Liquid

Thermal conductivity of is an important engineering property. The apparatus uses guarded hot plate method for determining thermal conductivity. It consists of hot plate i.e. an electrical heater sandwiched between two plates. The heat loss from hot plate is prevented by using two guard heaters and heat of removes heat from liquid by circulation of water. Input to heaters the temperatures.

SPECIFICATIONS:

1.Guarded hot plate assembly comprising of main heater, ring guard heater and top guard heater, mounted over the liquid test cavity. 2.Cold plate assembly provided with water connections. 3.The assembly is housed in an enclosure box with glass wool insulation. 4.Instruments panel consisting of : a).Digital voltmeter and ammeter of suitable range. b).Dimmerstat for controlling input to the heaters (2 amp. 3 Nos.) c).Multichannel digital temperature indicator.

SERVICES REQUIRED:

1.Floor space of about 0.75m. x 1.5m. at working height. 2.230v. AC electrical supply with earthling connection. 3.Water flow rate of about 10- 15 lit/min. at constant head.

Distributed Control System

A powerful, modular & upgradable DCS has been designed and configured based on Siemens controller SIMATIC PCS7 ASRTX (Micro Box). Distributed I/O system ET200M can be provided for field automation. The distributed I/O can be connected via Profibus, Communication. DCS consists of controller, Power supply unit, distributed I/O, Digital Input and Output modules, Analog Input and Output module. a Demo Panel and Simatic PCS7 V9.0 Software.

Band Brake Working Model

Consists of a brake drum mounted on a shaft, free to rotate in bearings. A flexible band is wrapped partly around the drum. Brake force can be applied with the help of Lever. Complete on iron base.

Theramal Conductivity Of Insulating Slabs

The apparatus consists of a slab assembly. The main Heater and a radial guard heater are sandwiched between copper plates. The specimen in the form of slabs of equal thickness are placed on either sides of heaters and cooling plates through which water is circulated are on the other Sides of the specimen. The radial guard heater ensures all heat of the main heater to pass axially through the specimens which is collected by cooling plates. By knowing the temperatures and Heat input, thermal conductivity of specimen can be calculated. The test set up is enclosed in an enclosure with insulation inside to provide undisturbed Surroundings. The design style of the apparatus is similar to as recommended in INDIAN standard. The difference is in sizes.

SPECIFICATIONS:

1.Heaters: a)Main heater plate 110 mm dia. with mica heater Sandwiched between copper plates. b)Radial guard heater plate I.D. 120mm and OD 200 mm mica heater sandwiched between copper plates. 2.Water circulated cooling plates -2 nos. 3.Dimmerstat-2 A capacity – 2 nos. to independently control Inputs to the heaters. 4.Measurements – A voltmeter and an Ammeter with selector switches to measure inputs,Multichannel digital temperature indicator to measure Temperatures at various points, having 0.1 °c least count. A technical manual accompanies the unit.

SERVICES REQUIRED:

1.230 V, A.C. stabilized supply along with earthing connection. 2.Water supply of about 4-5 lit/min. 3.Bench area 1m x lm x O.5m height.
