Exercise: $2.$ Component selection on conveyor belt

Subject : Electro $-$hydraulics

Training aim : To be able to draw and construct the electrical and hydraulic circuit for the

direct control of a double $-$acting cylinder.

Exercise objectives

$-$Defining the components required

$-$Drawing the hydraulic and electrical circuit diagrams

$-$Identifying the connections

$-$Numbering the components in the circuit diagram

$-$Practical construction of the electro$-$hydraulic control

$-$Production of the component parts list

Description of exercise

Components must be pushed from one conveyor belt on to a second conveyor belt by means

of a cylinder. The speed of forward travel is to be adjustable, while the speed of return travel

should take place uninfluenced. For this, you use a one$-$way flow control valve.
