michigan anvil Posted May 22, 2014 Share Posted May 22, 2014 Hello, I just finished and fired up a press built from the Batson Plans. The cylinder is moving very slow, the pressure gauge does not move. What am I doing wrong? The gauge is inline between outlet of pump and inlet to control assy. It does move up and down but, slow. I have used presses before and they have not done all of this. Quote Link to comment Share on other sites More sharing options...

bottles Posted May 22, 2014 Share Posted May 22, 2014 Have you gone through all of Batson's trouble shooting? What speed had you calculated for this ram and pump setup? My only thought would be how sure are you that the motor is turning in the right direction? Andrew Quote Link to comment Share on other sites More sharing options...
Glenn Posted May 22, 2014 Share Posted May 22, 2014 Confirm the gauge is operational and giving an close to accurate reading. Then check the pump to see if it is actually putting out pressure. Next continue to run checks on the system at each joint to confirm pressure. You may have junk blocking the lines, extra thread tape floating around, or all manner of things in the system. Once it gets to the cylinder and things still move slow, check the calibrations to be sure the pump and the cylinder match when movement you need when used together.

michigan anvil Posted May 22, 2014 Author Share Posted May 22, 2014 Andrew, I reversed the motor and it reversed everything the fluid discharged back to the tank from the pump in port and the discharge hose sucked up fluid. Glen, I have set the system up according to the Batson formulas, but, I will double check everything tomorrow. Thank You both for your input Quote Link to comment Share on other sites More sharing options...
Jim Coke Posted May 22, 2014 Share Posted May 22, 2014 Greetings Michigan, Sounds like a internal cylinder by-pass or a control valve pressure relief problem to me.. Press on Jim Quote Link to comment Share on other sites More sharing options...
swedefiddle Posted May 23, 2014 Share Posted May 23, 2014 Good Morning, I find it kind of silly, asking questions from a keyboard, about a project none of us have seen. Look for the most simple mis-connection or direction. Find a local hydraulic who is knowledgeable and ask/pay him/her for a bit of time to peruse your creation.

the iron dwarf Posted May 23, 2014 Share Posted May 23, 2014 ports on most control valves here are marked P for input from pump T for return to tank and A and B for outlet to cylinder also most have a diagram on them showing the different states, first box shows P connected to either A or B and T connected to the other next box shows P and T connected together last box shows the same as the first but with the lines crossed there are many types of different control valves, some are unsuitable but the above is the most common for single cylinder operations that I would use, I would also have valves for speed of flow and for pressure relief. can you post pictures?
