2023.06.03 04:57 Sollant-Compressor How to prevent the burnout failure of the screw air compressor oil core?
![]() | submitted by Sollant-Compressor to u/Sollant-Compressor [link] [comments] The oil separation core is one of the important accessories of the screw air compressor. It is to separate the oil and gas, let the oil return to the internal circulation of the air compressor, and let the gas be discharged for the user. At the same time, the oil separator core is also a vulnerable consumable, and it needs to be replaced in time after it expires. The failure of the oil split core to burn is actually the oil split core being ignited. So, what are the measures to prevent the air compressor oil split core from burning?

2023.06.03 00:15 Many_Standard1512 Wiring help
![]() | So I'm kind of new to all this, and have a question about wiring. I bought a Skar sk-9005d amp, spx-65c components for the front doors, tx-69 speakers for in the back, and a vd-10 dual 4ohm sub to replace my stock subwoofer using my stock enclosure (this is going into a 2009 Chevy Cobalt SS). My question is what's the best way to wire the subwoofer to the amp? I know if I wire the sub in parallel it will drop it down to a 2ohm load, which the amp can handle, but do I then bridge the amp as well? The amp has 2 positive and 2 negative connections for the 5th channel, but I'm not sure the best way to run them to the sub. To I run a positive and negative to each voice coil like in the first diagram, or do I run both positives and both negatives to the coils like in the second diagram? Any help would be greatly appreciated submitted by Many_Standard1512 to SkarAudio [link] [comments] |

2023.06.02 22:17 bengalsbyamilly NO sound from head unit 🫥
![]() | I’m getting no sound from my iDrive head unit. submitted by bengalsbyamilly to CarAV [link] [comments] I have a 2011 bmw 335d e90 with base audio, 6 speakers and no amp. The front 2 door speakers are in parallel with the front 2 under seat subwoofers. The rear deck speakers are ran separately on their own lines but have a high pass filter so I can’t tap into that for any bass. I had everything wired previously and it all worked as it should. I have a spare sub in a box with an amp and everything already mounted ready to go. I got bored one night and decided to throw it in the truck of my car. I wired everything up and spliced it all together, etc. and it all worked fine and the sub played like it should. I decided I didn’t want to take up that much trunk space with a big subwoofer box so I decided to run a spare 4 channel amp I have laying around up to them instead. My plan was to replace the rear deck speakers and run the 4 channel amp to the 2 rear deck speakers and also to the 2 under seat subwoofers. I wired everything together and got nothing. I doubled checked it all and realized I had the subwoofer speaker signal taps for the line out converter mixed up with the wires than ran to the actual front subwoofer itself. So, I had my amp hooked up running 4 channels but 1 of the 4 channels was running back into the stock audio system which runs in parallel. Ever since I wired it up that way I haven’t gotten any audio from the car but I will get a hissing/scratchy noise from this subwoofer. It still works fine though, just no sound..? The line out converter I used is just a basic one (Scosche LOC2SL) which worked fine for the mono amp and sub when I tried. I used the same LOC for the 4 channel amp when I wired that up but obviously the 1 set of wires ran back into the system. I get 0 audio now after that happened where as before it all worked as it should. I was wondering how to check my iDrive head unit maybe with a multimeter? I wired it back to stock form again and still don’t get ANY audio. The whole reason I started this project was I was bored and already had all of this stuff sitting around so I didn’t have to buy anything 🤣. I’ve checked fuses and they were fine but I haven’t checked the MOST system or whatever it’s called. The MOST/fiber optic system is all new to me so I’m learning that right now lol. My head unit and all of its features work as they should no problem, I just don’t have ANY audio for literally anything. I’m not really sure how to check the head unit to see if it’s fried or not either. I should also note that all front 4 speakers (2 doors, 2 under seats subs) were all 4 ohm but when I replaced the under seat subs those are 2 ohm. Front doors are 4 ohm and under seat subs are 2 ohm. All four are single voice coils. The stock head unit is 2 ohm stable and ran that way fine ever since I installed them in 06/2021. I forgot I ordered 2 ohm instead of 4 ohm and noticed that when my amp wouldn’t put out any signal to my speakers but wasn’t in protect mode. The video attached is what I get when I hook up the + and - to the sub while the car is off. (Battery still hooked up, just not on accessory mode or anything) When it gets power (no audio or sound) it will click and pop like in the video. The cone itself sucks itself down towards the magnet when connected and will stay like that permanently while connected. It will put off a very faint hiss/scratching noise while connected. After letting it sit for like 5 mins connected the middle of the cone was pretty hot so I disconnected it and this is where I’m at lol. I know I messed the system or whatever up probably, I just want to know how to check it all to narrow it down if anybody has ideas and is somewhat familiar with this system. I’ve always wired a bunch of stuff up in 10+ cars of mine without a problem but you can’t win them all I guess 😅 |

Motherboards | ||
msi b660m mortar wifi ddr4 | mobo vrms have coil whine crackle-hum using turbo boost, most likely related to powerstate/frequency switching (disappears when fully loaded or not doing anything) or concurrent with putting load on the integrated graphics, tried a whole bunch of bios settings to stop it, C1E enabled reduces it. integrated graphics culprit unverified due to case and difficulty with it; haven't tested a discrete card to eliminate igpu cause. latest bios(v19) at the time is flashed, need earlier bios version for avx512 capability, tried to get that instruction set working but found out it involves tainting my kernel and i don't use windows but if you do, the only os-side step is to move the specific intel microcode file out of system32. replaced the ilm with the thermalright one. includes right angle usb3 header adapter. | 100/100 |
msi b660m a pro ddr4 wifi | 2nd hand from 12400 guy. has smudge on backside near cpu bracket from alcohol solubility test on the paint; backside is alcohol soluble. has same scent as others from him. he did a bad paste job on cpu area and shipped it that way, i cleaned it up (no socket pins got paste on them thankfully because he didn't remove cpu from the board) tested and it works. comes with windows 10 pro key. the m.2 wifi card was worked, but putting it back in this board... i didn't have enough finger dexterity. one of the contact n!pp!es is bent, needs to be bent back. can't get it back out to do that, stuck. includes piece of factory glue that goes between the contacts and holds the leads in place. treat as non wifi version with potential bonus for trying hard enough. anti static bag on one side MAY have trace of urushiol due to being blown away when airing out onto a patch of cracked concrete where two weeks previously had been a sprout which had been disposed of then the area alcohol-doused then two rainstorms. includes right angle usb3 header adapter. | 80/70 |

timetec 2x16gb 3200 c16 | dual rank with hynix 8gigabit jjr ic's (lower binned cjr) remember to lock in the voltage to safe level for that ic instead of auto. partially manually overclocked, enabled xmp then increase to gear1 3466mt/s (what i can tell, max speed with the locked vcssa without loosening timings) and the few timings changed are: command rate to real 1N; did not test tighter than tRRD to 6, tRRD_L to 6, and tFAW to 24; tREFI should be able to be higher than 24960 but didn't test; tRFC has errors at 460, can't remember what 480's result was, and 500 is stable. stressapptest for an hour after each change made, no errors. may go tighter, less than 10 attempts worth of tweaking. | 70/65 |

GPU | ||
xfx rx460 4gb | 2nd hand from a miner in 2021. was dirty but cleaned it, had mining bios, and the standard bios or other custom bios don't seem stable, but it works with a rx560 bios i modded to rx550 clocks. thought i saw something spherically, iridescently marbled green-yellowgreen falling from it when putting it back together after cleaning but couldn't find the drop or where it may have dropped from, capacitors look ok. single fan version. has annoying blue led. requires 6-pin pcie power even though it draws less than 75w. | 45/35 |
Cases | ||
sama im01 | hohboy, man oh man, this case.... removing the front panel carefully according to the manual causes the top clips to break(so that's why it includes two spares), and is difficult to work in even though all sides but the back come off. can't put a discrete gpu in because it can't go into the slot all the way; something about the mobo tray being depressed or pci slot design prevents it. front left usb3.0 defective (blips then doesn't work) but the right one is functional. pci slot magnetic swinging screw cover hinge is a bit bent because the top and bottom packaging foam were switched in factory(foam cutouts did not align). matx mobo prevents bottom from having second fan if not want to risk mobo header bending. | 60/30 |
lian li lancool 216 black non-rgb model | opened the box and took out the inner accessory box on top but put it right back because became busy and never got around to using it. did not take out the case. almost literally open box. do not know state of tempered glass but jiggling box does not make broken glass sound. | 100/90 |

corsair sf600 platinum | 3 months use. powered the 12400 using integrated graphics, don't think total system power exceeded 150w from the wall. | 110/110 |
thermaltake tr2 430np | don't know if it was 2nd hand or not. used to power a windows xp office machine which was bought without one. Don't use more than 350 watts; here is a review of the unit showing why- https://www.hardwaresecrets.com/thermaltake-purepower-430w-np-power-supply-review/ its F-tier but would personally trust it in a system pulling less than 100 or so from the wall. one cable with 20+4-pin motherboard connectors one cable with 6-pin pcie connector one cable with 4-pin 12v connector one cable with 3 molex connectors two cables with 3 molex and 1 floppy connector one cable with 2 sata connectors one molex-to-sata converter | 20/5 |

hp zr24w + ergodepot J2 monitor arm | 60hz, 1920x1200, 24inch. 12 years use. ccfl backlight has been on for ~3.3 years. came with a scratch not noticeable when on most of the time. has smudges from over a decade of use, not trusting myself to clean it without scratching. includes J2 monitor arm (desk clamp), but makes it skew a little. when powered on, it knocks channel 6 out of the airwaves until it is turned off. flickers below 100% brightness. | 50+40?(90?)/50+20(70) |

presonus eris E3.5 studio monitors | were on my desk for 10 days and powered on at low volume for under an hour, may be low amount of specks of dust, and the speaker wire had been connected, but otherwise is as if you opened up a new one. didn't like the space they took up and preferred my headphones, but B&H would not take these back because i told them i used the included speaker wire. no joke. | 90/80 |
samson go mic | 2nd hand. works, good shape. usb condenser with omni/-10/cardioid switch and 3.5mm jack. has sticker covering the led to diminish the brightness. | 25/15 |
xbox 360 wired controller | didn't use it often, but owned it for a really long time. the left thumbstick has worn down, is low tension, and can drift slightly if off center to the northwest. | 10/4 |

2023.06.02 13:25 WackoKacko Enquiry: Looking for a consultant to advise on medium-power INDUCTION COIL AND SYSTEM design.
![]() | I'm an engineer working for a sci-fi enterprise, 42AD, which is trying to make a food printer for home use. We need your expertise. submitted by WackoKacko to consulting [link] [comments] My team and I have decided to use induction heating in our design, but we lack expertise in coil design. We have a cylindrical chamber (Ø100mm/H80mm) that we are trying to heat with a pancake coil (4-5mm stranded enamelled wire). I've attached two images to make it easier. During prototyping, we have ran into the problem that the induction heating module we have, capable of 1kW—DC supply, Royer oscillator topology—is only drawing 600W. In our final design, we are looking to have up to 1.6kW output to the chamber for rapid heating—single-phase AC supply, Half-bridge topology—and I ask for your consulting services to help us get there. We need to solidify our criteria for the heating module design, and your expertise is needed here, too. Finally, we would be interested in small-scale manufacturing of the coils once the design is finalized. We would like to find out about what's out there in terms of industrial techniques for efficient stranded-wire coil fabrication at scale. If interested, please let me know when you could arrange a meeting with me and how you'd like to invoice me.
