Hi,
I have received a set of drawings through for a frame I'm going to be making, but to be honest I don't fully understand the weld codes and symbols. Usually I'm welding up most of my own drawings and know from experience where and when I need to weld.... no problem. But in this case it's...
Hi,
I'm trying to design and make a Co2 vent valve which basically releases pressure from a larger pilot valve causing actuation. I am using the small 16g Co2 cartridges which provide 55 bar of pressure. My vent valve is basically the same as a direct acting pressure relief with a manual pull...
Hi all,
I am wanting to reduce the 852.8 psi of pressure from a 12g CO2 cartridge. My application would ideally require 3 times less pressure at roughly 284 psi.
I know there are pressure regulators, relief valves available. But in theory if I was to screw a 12g cartridge into a vessel /...
Hi,
I'm machining threads on to the ends of chrome rod for use in hydraulic rams.
I have a ram which will see a maximum retracting load of 10 ton (98.1kN). For this I'm considering a thread of M30x2mm pitch. The chrome rod we use has a tensile strength of 550 n/mm2 with a yielding of 420 n/mm2...
Hi,
I'm looking to build a 3 axis cnc machine about the size of a van.
All 3 axis will be controlled by hydraulics and actuators will consist of 2 hydraulic motors (x axis), 2 rams (Y axis) and 1 hydraulic motor (y axis).
I was thinking of using rotary encoders connected to each axis and fed...
Hi,
I'm having problems with an old 1989 NUM TSX 17.20 plc which runs on one of our older CNC lathes (Somab Transmab 400).
Basically the main 3-phase contactor is not being energised by the PLC. The trigger circuit for the contactor goes through numerous safety switches and numerous relays...
