Operate the dump hopper using double acting pneumatic cylinder.

Problem Description: -

Material is to be emptied from the dump hopper. By pressing PB1 ,the dump hopper will be tilted, and bulk material is emptied out and by pressing the PB2 hopper is returned to its original position. 

 

Problem Diagram: -






Pneumatic Circuit: -




















Solution

As Shown in diagram we can see one double acting pneumatic cylinder is used to tilt the hopper. With the cylinder open/close operation we can operate the hopper. We used two Push buttons to operate the hopper. So once operator press PB 1 , hopper will tilt at some angel and loose material will come out from the hopper and if operator will press PB 2, hopper will return to its home position.

Pneumatic circuit explanation: -

As shown in pneumatic circuit diagram, we need double acting pneumatic cylinder to operate hopper. Here we used two 3/2 valves and one double acting pneumatic cylinder for the application. If operator press PB 1 then Air flow will move from P to A so cylinder rod will come out and it will tilt the hopper. If PB2 is pressed, air flow will move from P to B so hopper will return to its original position.


Note: -Above application may be different from actual application. This example is only for explanation purpose only. We can implement this logic in other way also. All parameters and graphical representations considered in this example are for explanation purpose only, parameters or representation may be different in actual applications. Also, all interlocks are not considered in the application.
