And thanks for you a lot Jim Pytel,, I am enjoying your videos and learning a lot, the way you are explaining every single point makes me very proud that their is amazing people like you in this world. God bless Jim, and keep it up.
@@bigbadtech que bueno! Hablás español? I was looking for hydraulic diagrms help and found your videos! Do you know of any simple (and free hopefully) software to draw basic hydraulic diagrms? Or i have to do it on CAD?
Claro. I've used both FESTO's FluidSim and HydraForce's I-Design. I've also heard good things about Automation Studio. Everything I've done is hand drawn!
@@bigbadtech it looks nice to be hand drawn, and thank you, i'll check those software, i just want to draw a simple irrigation system, but i want to do a nice diagram btw, i love the intro in your videos jajaja
Welldone Jim Pytel , HAVE being your active follower of your post at Columbia George college . Your detail lessons are explanatory and embracing even to fresher in the field. Thank you…
Hello Jim, I cannot find the lesson where You explained about DC and AC solenoid valve coil"s supply. That funny description with the lizard stuck inside the solenoid valve. Do You remember what was the exact lesson? Thank You in advance.
Hi Mr. Patel. As I progress through the courses, I'm wondering if you provide worksheets or something along those lines. Thank you for the amazing tutorials. 😂
I don't have study guides/worksheets for all of them just yet however here's where you can find them for the electrical circuit analysis and hydraulics playlists: openoregon.pressbooks.pub/electronics1/ openoregon.pressbooks.pub/electronics2/ openoregon.pressbooks.pub/electronics3/ openoregon.pressbooks.pub/hydraulics/ Working on the motors and generators and pneumatics study guides this summer and next academic year.
Thank you Jim! I think that solenoid coil may be damaged only if operated by AC current, when plunger is stuck. If solenoid is DC-operated, then coil will be safe. Am i right?
Yes, DC coils are known to have significantly reduced inrush because. Ironically enough often the problem with DC coils is when they're de-energized a brief voltage spike can occur because they're acting like an inductor with an established magnetic field that is collapsing. For this reason some DC coils include a "free wheeling" diode in parallel with the coil to dissipate this stored energy when de-energized. These types of coils are polarity dependent. I'll actually cover this phenomenon in detail when I introduce the inductor in between the DC and AC circuit analysis playlist.
Thanks, Jim! It would be great to make video about DC coil induction spike and diode protection. If you can, also add information about AC coil spike (MOVs, RC snubbers).
