    What do these hydraulic symbols mean?

    I have a hydraulic schematic and this is really bothering me. I don't know what they mean. I'm assuming their some sort of gauge.http://i62.tinypic.com/2n9f02o.png

    Cleaning of salt bath nitrided parts

    The company I work for salt bath nitrides ductile iron (80-55-06) parts. I'm having a heck of a time getting these parts clean. After then parts are pulled out of the salt bath their quenched. They are then wire brushed,then tumbled, then sonic washed and preserved. It seems no matter how...

    Jib Crane Anchor Bolts

    I'm looking to purchase a Jib crane for my work. I've been in talks with a company who gave me the following information. The over turning moment is 60,833 in-Lb and the bolt pullout force is 2150 lbs. Using a recommended safety factor of 4, I should design around a bolt pullout force of...

    Does anyone know of any places that will go gas nitriding in the Midwest? Preferably in the Nebraska, Iowa or Kansas region? This will be high volume.

    Cleaning cast iron and steel parts

    CoryPad thank you for your response. I will check those manufacturers out. Is there any new state of the art cleaning processes out there? Or is sonic cleaning pretty much the best there is for this application?

    Cleaning cast iron and steel parts

    What is the best way to clean cast iron and steel before an item is assembled? Right now we're using sonic washers, but this is not getting the job done and is not very efficient as we have to load the parts into the cleaner then manually blow off the washer with shop air. Is there any new...

    Cleaning Cast Iron Before Heat Treatment

    We currently sonic wash all of our castings before they go into our molten salt baths, but it doesn't clean them will enough. I have been readings into better ways of cleaning and came across electrolytic cleaning. Has anyone done this before and does it work well in a manufacturing...

The questions I have are over maintaining the pot chemistry, mainly the cyanide and cyanate level. If anyone has any experience with this process please let...

    Let me go a little more in depth. We build the pump then attach fittings and plugs to make it air tight. Then we connect air at ~ 15 psi and dunk it in a tank of water with a rust inhibitor. Once that is completed, the excess liquid is blown off the pump and then the pump is tested and set at...

    Hydraulic pump leak detection.

    Just wondering if anyone has any experience with this? The company I am working for currently dunk test their pumps in water to check for leaks. I think dunk testing is a good, quick test, but it absolutely terrible for our application, as water and hydraulic systems don't get along. Some...

    Variable displacement axial piston pumps

    Just have a quick questions. In variable displacement pumps, does the swash plate continuously move in a reciprocating motion? Or once you set the swash angle, does it stay stationary at this angle?
