construction and details of pneumatic bench vice

The goal of this project is to create a model of bench vice which is pneumatically operated. Using air pressure to create mechanical motion in the spindle of the vice provides a safe & efficient way to reduce human effort.
The mechanical motion in the spindle is created with the help of a double actuating cylinder which is operated by a 5/2 pilot valve & two 3/2 push buttons with the help of the air hoses.

KEY BENEFITS

Gripping through manual screw adjustment and quick clamping through Pneumat ....etc

Hydraulic bench is a very useful apparatus in hydraulics and fluid mechanics. It is involved in majority of experiments to be conducted e.g. To find the value of the co-efficient of velocity Cv , coefficient of discharge Cd , to study the characteristics of flow over notches, to find metacentric height, to find head losses through pipes, to verify Bernoulli s theorem etc.

Parts of Hydraulic Bench Machine:
Its parts are given below:

Centrifugal pump
It draws water from sump tank and supplies it for performing experiments.

Sump Ta ....etc

Abstract

The people in rural areas of Karnataka and Kerala mainly depend on agriculture for their livelihood. The main crops grown are Arecanut and coconut.
For harvesting the nuts, and for spraying and applying insecticides on the crown, skilled labourers have to climb manually up the tree. Such a process looks easy, in reality it is a laborious and dangerous task. It requires skill to climb a arecanut tree. Skilled arecanut tree climbers have become scarce and farmers are finding it difficult to harvest ....etc

A compressed-air vehicle (CAV) is powered by an air engine, using compressed air, which is stored in a tank. Instead of mixing fuel with air and burning it in the engine to drive pistons with hot expanding gases, compressed-air vehicles use the expansion of compressed air to drive their pistons. One manufacturer claims to have designed an engine that is 90 percent efficient
Compressed-air propulsion may also be incorporated in hybrid systems, such as with battery electric propulsion. This kind of system is called a hybrid-pneumatic electric pr ....etc
