Compressing air using weight

[mrwaustin]

I want to compress air using the weight of a tank of water. Under the tank I propose some form of positive-displacement cylinder -perhaps a ram or spring return type cylinder.

The tank will be supported in such a way so that it will move along with the cylinder. When filling up the tank the weight should cause the cylinder to compress the air. When I drain some of the water the tank will recede to its original position and draw in more air until the tank is refilled.

My question is: What type of cylinder is best for this? And can you refer me to a site or vendor for the cylinder?

Thanks,

Michael Wright

Just do a google search on pneumatic cylinder or air cylinder.

Hello Michael,

Thank you for sharing your idea for compressing air using the weight of a tank of water. It is an interesting concept and could potentially have practical applications in the field of pneumatics.

In terms of the type of cylinder that would be best for this setup, it would depend on various factors such as the size and weight of the tank, the desired compression ratio, and the intended use of the compressed air. Generally, a positive-displacement cylinder that is capable of producing high forces would be suitable for this setup. A double-acting cylinder, such as a spring return type, would also be a good option as it allows for compression and expansion of the air.

As for a specific vendor or site for the cylinder, I would recommend researching different pneumatic cylinder manufacturers and suppliers to find one that offers a suitable product for your needs. Some popular vendors include Parker Hannifin, Festo, and SMC Corporation. It would also be beneficial to consult with a pneumatics expert or engineer for further guidance and recommendations.

I hope this helps and I wish you success in your study of pneumatics. Keep exploring and innovating!

Best,
