Cam Analysis Apparatus

The apparatus is designed to study the cam profiles and performance of cam and follower system. The apparatus consists of a shaft supported by ball bearings upon which three different types of cams can be mounted. The push rod for follower is supported vertically, which can adopt three different types of followers. Cams and followers can be changed easily. A variable speed motor rotates the cam. A dial gauge permits plotting of follower displacement with respect to cam position. By operating the system at different Speeds, jump speed can be found and also the effect of weight and spring force on jump speed can be studied. Jump can be visualized also with the help of stroboscope (it is not supplied With the product).

SPECIFICATIONS OF CAM ANALYSIS APPARATUS:

1.Cam -Eccentric, tangent and circular ARC type – one each. 2.Follower- mushroom, flat faced and roller type – one each. 3.Cams and followers are hardened to reduce wear of the surfaces. 4.Variable speed motor coupled to camshaft of suitable range and Variac. 5.A dial gauge to note the follower displacement. 6.A technical manual accompanies the equipment.

Hydraulic Ram Test Setup

DESCRIPTION:

The Set-up is designed to study the Hydraulic Ram. Hydraulic RAM is used for pump little quantity of water to high head from a large quantity of water available at low head. It works on a principle of water hammer stating that “When flowing water is suddenly stopped in a long pipe a pressure wave travels along the pipe creating an effect of water hammer”. The Set-up consists of a pipe section fitted with a pulse valve and non-return valve, a supply reservoir on a stand which is connected to an overhead tank, an air vessel above the valve chamber smoothes cyclic fluctuations from the Ram delivery. Different pressure may be applied to the pulse valve to change the closing pressure and hence the operating characteristic. The flow rate of useful and waste water is measured using measuring tank and stop watch provided. Pressure and Vacuum Gauge are connected on delivery and suction side for the purpose of measurement.

EXPERIMENT:

Ø To find out discharge of useful water and waste water. Ø To find out the efficiency of the Hydraulic RAM

FEATURES:

Ø Closed loop water circulation Ø Compact & stand alone set-up Ø MS Excel sample calculation program on demand Ø Stainless Steel tanks and wetted parts Ø Superb painted structure Ø Simple to Operate & Maintain

Ø The whole Set-up is well designed and arranged in a good quality painted structure.

Emissivity Measurement Apparatus

The apparatus consists of a test plate and a comparator. A black plate is used as a comparator for test plate. When all the physical, dimensions and the temperatures are equal, heat losses from both plates will also be the same, except radiation losses. Hence the input difference will be due to difference in emissive. Both the plates are kept in a panel enclose with perplex front and are given inputs through separate dimmerstats so that temperatures of both can be kept equal. Thus emissivity can determine over a wide range of temperatures.

SPECIFICATIONS:

1.Test plate and Black plates — 160mm. Dia. Aluminum plates, mounted in Panel with mica heater inside. 2.Instrumental panel consisting of- a)Voltmeter and ammeter for input measurement to both heaters through a selector switch. b)Separate dimmers for both the plates. c)Multichannel digital temperature indicator. A technical manual accompanies the unit.

SERVICES REQUIRED:

1.Space area of 1.5m x 1 m. at working height. 2.230v, 15A, AC supply with earthing connection
