Talk:Pneumatic cylinder

From Wikipedia, the free encyclopedia

[edit] Work needed. Made a start

There is a lot of work needed on this article. I have made a start to trying to structure, wikify and tidy the article. Will need to modify some of the wikifications to align with the existing terminology on Wikipedia. A good place for information as it's function and fundamental theory are similar is hydraulic cylinder. However, they are not identical so it is important not to just blindly copy and paste stuff unless you know it is correct and understand what it means.-*- u:Chazz/contact/t: 22:27, 6 April 2007 (UTC)

[edit] "Actuator" term

In pneumatics I have always understood the term "actuator" to mean switch (i.e. an item that actuates another item) and always called a pneumatic "switch" an actuator. What's more, this is consistent with the definition from dictionary.com which is: "1. a person or thing that actuates. 2. a servomechanism that supplies and transmits a measured amount of energy for the operation of another mechanism or system.". Now, although pneumatic systems (including those with pneumatic cylinders as their end effector) can be used to turn on (or "actuate") other devices, not all do. A significant proportion, if not most, pneumatic devices just provide a force to perform a direct task (like move a car). However, in this article and Wikipedia's article on pneumatics it would appear that this term is taken to mean "pneumatic device". This usage of the term is inconsistent with the above. Anyone got ideas? -*- u:Chazz/contact/t: 22:27, 6 April 2007 (UTC)

• In the pneumatic industry, there are pneumatic cylinders, and then there are grippers, escapement mechanisms, rotary cylinders, and multi-motion devices that are clearly not cylinders, but do actuate when appropriate signals are recieved, based on the system that they are part of. Thus, these items are generally referred to as Actuators. —Preceding unsigned comment added by 64.132.87.2 (talk) 16:34, 18 September 2007 (UTC)

[edit] what about the cylinder length

In calculating the force cylinder length both in forward & return stork is not at all consider. is there any variation due to the length. if yes please reply the same with formula top www.G.Mugunthan@tvsmotor.co.in —Preceding unsigned comment added by 203.101.98.215 (talk) 11:49, 4 September 2007 (UTC)

In theory length of cylinder makes no difference. However, i suppose as length increases, frictional force opposing piston movement may vary. However, I don't think this has a significant effect and as far as I am aware isn't considered in industrial application. -*- u:Chazz/contact/t: 20:46, 27 January 2008 (UTC)
