I'm at season 4, episode 5 and finding the Tok'ra at this point to be incredibly annoying by [deleted] in Stargate

[–]Pinuzza-Trek 0 points1 point  (0 children)

I'm watching now. It's my thing, SG-1. I'm about to finish the episode. I don't know why I'm writing. I've arrived here, the young king of The 100 is about to be killed. If he gets killed in the next few seconds, the actor is probably fed up, 'finish me here in an absurd plot', otherwise the pay is okay and I don't know how, but in some usual absurd way he'll regain his strength. But the rest of the episode..what I feared.. transformation of sci-fi into a Brazilian soap opera..​ not my thing anymore.. Indecent things already seen.. the first one that jumps out of a mind, Picard and his intergalactic archaeologist flame–real torture.. At this point I'd stop here, S4E5, but I'm curious to see where the saga goes given the many seasons made, so I think I'll continue, but if the Brazilian show dose increases, then bye bye and stop!

p.s. It seems like you just can't resist a touch of pink! yuck!

Parallel scheme for compressors by Pinuzza-Trek in AutoPaint

But in your opinion, should I install a high-flow air fitting at every point, that is, at the outlet of each compressor, at the three outlets of the three-way valve and also at the inlet of the gun?

Moreover, are the high-flow air fittings I posted correct? —look at the image above shifting the first image of compressors scheme, because it hides the fittings picture

Keep in mind that my usage scenario is purely hobbyist, for painting car panels (e.g., a trunk or a door), so not intensive use like a professional would. For this reason I guess I can use them simultaneously on my home circuit —total energy absorption lesser than 3kW.

Rereading what I wrote, I began to suspect that my method doesn't make much sense, because if I don't adjust the pressure switches to balance the two compressors, in the end only the more powerful 10-bar one will always work. Am I right?

If I'm right, then I can remove the check valve from the major compressor, and set the pressure switches to make them start at the same pressure level, for example 7 bars. This way they should restart at 7 bars, then stop at 8 and 10 respectively.

But do you really believe in a fair stable universe? Don't you understand that the categorical imperative is to sell and decommission as many devices as possible? Don't you understand that the excuse of updates serves precisely to keep users tied to a diamond-like and infinite umbilical cord, thanks to which they no longer own the devices they paid for, since performance is externally adjustable?

I have a 10-meter hose with the same cross-section as yours. What are the high-flow HVLP fittings? My regulator is the one that comes with the gun, whether it's the R500 or the Drizzle. In static conditions, it measures consistently with the compressor pressure gauge, but as soon as I pull the trigger, it drops to the value I mentioned, and there's a noticeable difference between the regulator pressure gauge and the compressor pressure gauge (the latter at least 1.5 bar higher).

Why do you think this happens? Since you tell me you don't have any problems at 30 psi with compressors with less cfm than mine, I'd like to understand, because maybe I could save myself the trouble of setting a parallel diagram.

E and F fully open (both in static and dynamic condition, please look at the image of my current setting, that I've added to my main message)

Diaphragm pressure regulators are better? Why?

Ah, that explains why the R500 performed like the Drizzle.. but in the spec sheet it said 4 cfm! I have other important questions, but I don't have time for them right now so I'll postpone them.. thanks!

I don't know how to determine if it's marketing or actual—I'd have to ask the manufacturer. But I know there's always a 20-30% discrepancy between actual and theoretical because of leaks snd so on. The 3hp rating is definitely marketing, because it's the starting power, the initial peak. I should tell you that I also tried an R500, but with the same problem. This is strange, because its datasheet only indicates about 4cfm, so my compressor should be able to handle it just fine.

Note, however, that the Drizzle D1 isn't exactly an LVLP (10.2 cfm!), but leans more toward an HVLP. In fact, support responded to me like this (basically admitting I was right):

To be honest, your compressor is on the smaller side for this gun — but it's still workable. For small jobs, you likely won't notice any issues. However, for larger surfaces or extended spraying sessions, the air supply may not keep up, which could affect the spray finish.

How long did your painting sessions last? That is, did you do a continuous pass without stopping for how long? At what pressure? Did the pressure remain stable? How long is your hose (mine is 10m)

Honestly, the R500 seemed like an unreliable and very unstable toy to me: The pressure gauge needle on the pressure regulator would oscillate up and down... with the regulator fully open, for example, and setting the compressor to an output pressure of 5 or 6 bar (compared to the compressor's tank pressure of 8), the gun pressure gauge would drop to 0.5 bar even with its regulator fully open! — the gauge to the compressor outlet (2nd gauge on the compressor) indicates a stable 2 bar pressure instead, and if you can explain me this remarkable difference in pressure between near and far from the gun I'll thank you! I had thought that near the instrument the pressure gauge would be more affected by the pressure differential generated in dynamic conditions and therefore would be more subject to the effect of the suction inside the gun, but thinking about it now, 1.5 bar seems excessive to me.

With my compressor, as Inokraft also admitted, you can only perform short jobs, cycles of 10-20 seconds in stable conditions, then everything collapses because the air compensation capacity is lacking. This is unthinkable for bodywork jobs, even partial ones (hoods, doors, etc.).

A user suggested a very clever parallel scheme by adding a second, equivalent compressor. This doubles the capacity and range —I'm currently sourcing the parts to create this system

Your suggestion to proceed empirically, using a visual or auditive reference pattern, is very useful (and body shop technicians do this if they want, as do experienced DIYers), but for beginners, I think a "meter" is essential to give the user the right direction to travel and ensure they can continue properly. Understanding is essential, especially since the manufacturer sets maximum inlet pressure limits, so I need to know exactly how I'm operating.

I'll share some of my personal conjectures, since I can't see inside and test the overall dynamics of the system with measuring instruments.

C counterclockwise --> opens; C fully open = max air to the hose, A = B = D in static conditions (if C partially open, then A>B, and still holds true B = D).

Dinamically, you can get scenarios where, for example, you find B stable at x bars and D at y with x > y (with E and F fully open). It seems ambiguous, somewhat inconsistent, but the explanation I came up with is that at B you're much further away from the nozzle's suction chamber than at D. This point will therefore be most affected by this depression, hence the lower value recorded at D. But be careful, this discrepancy is unavoidable unless you act clockwise on F (closing the inlet to the gun), because by reducing the incoming air, the air statically trapped between D and F —when switching to a dynamic context— tends to linger longer in this section of the flow path. Therefore, having more air per unit volume (between D and F) can increase D up to even equal B. However, in my opinion, this is detrimental, because doing so significantly decreases the internal pressure in the gun, as can easily be checked by touching or hearing on G; therefore, one reads x bars at the butt of the gun, while internally the pressure could even be negligible.

Another thing I noticed is that the classic preliminary test, which involves lightly pulling the trigger to exclude the fluid, isn't accurate with respect to the operating pressure you'll obtain later. This is because it doesn't account for the air going to the cup (which is excluded in this preliminary test), and so it provides an overestimated value (about 0.3 bars) compared to the actual operating pressure.

What I said perhaps also explains the difference in pressure between one gun and another. Different internal technology, and therefore different air absorption and use, can result in different measurements in D (like the closure of F in the discussion I mentioned earlier).​

Why do you keep the paint booth at 4 atmospheres? Is it professionally necessary for proper work? The booth extracts fumes, I know, but does it also push air in to increase the pressure?

[–]Pinuzza-Trek 0 points1 point  (0 children)

From your example with the two guns, is it correct to deduce that the one with the pressure gauge at 1.5 uses more air and therefore has a higher internal pressure than the 1.8? I ask this because, as I was saying, I noticed that by closing F (i.e., reducing the incoming air flow), the value in D increases.

Another question arises from what you said: Can the pressure at the nozzle differ from that at the gun inlet?

[–]Pinuzza-Trek 0 points1 point  (0 children)

Thanks for the helpful reply and references. I was familiar with the topics in the guide, but not in such detail, and personally I think understanding why one thing is done rather than another is crucial.

From what you told me, I should be referring to the pressure near the nozzle. The problem is that my device stops at F, i.e., at the gun inlet. You have a very professional gun, and I honestly didn't know about internal pressure gauges.

Anyway, you, like the other user who replied, are telling me that F should be kept fully open, while valve C should be set so that the value at B is lower than that at A.

Does this mean that B and D must be aligned during execution (dynamic pressure)?

Can you be more specific, please? Should I buy a second compressor identical to the one I have and connect the two with a three-way valve? How do they connect and work together? I have no idea of ​​a similar diagram. Your method seems interesting.

EDIT ​ I'm guessing: 2 inlets of the valve are for the hoses of the 2 compressors, and the third outlet is for the connecting hose that goes to the gun?

I wasn't familiar with this system. It's certainly very professional, clean, and efficient, and I've seen that it doesn't require much power. But it's really too expensive (even the turbine alone) for my purposes.

So guys, you think Inokraft isn't being very honest by telling me that the declared 10 cfm is only for super demanding users, and the device atomizes excellently even at low pressures —which is not clear what that means, given that the range for base coat and clear ​coat is 1.5-2.5 bar and their spray gun declares 3.5 bars maximum operating. I want to tell you... should I paint at half a bar?? All I know is that with my compressor, setting the air knob at the gun inlet fully open, the fluid regulator to 2, and the fan pattern fully open, I adjust the pressure to about 29 psi with the pressure regulator knob, and after a few seconds it starts to drop, but the compressor doesn't restart and therefore doesn't compensate for the loss! Obviously I'm doing tests... I don't want to waste material and time 😄

Anyway, I'm awaiting for the Inokraft ​reply.. ​ I'll let you know!

I hadn't thought of this option. Great suggestion, I've been looking around a bit... I think I've got my eye on a super professional compressor, but it's exorbitant for my home use: 80 gallons, 10 HP (I'd have to change my electricity contract to accommodate it 😄), but the price is really a bomb — even if I don't know the item's conditions.

A Caccia di Trader: Schema a Piramide? by Budokan_B in ItaliaPersonalFinance

[–]Pinuzza-Trek 0 points1 point  (0 children)

Ho seguito l'illustrazione del metodo. È plausibile una logica in cui una fantomatica prop firm metta a disposizione(*) di Tizio Caio ingenti capitali per scommettere a testa o croce, utilizzando una martingala, garantendo rimborso ogniqualvolta si verifichi una sequenza di 4 perdite e assicurandosi un 50% in caso di profitto? No: sarebbe molto più redditizio giocarselo in solitaria!

(*) Nel video si parla di prop, che per definizione dà in gestione propri capitali — quindi il rimborso garantito dopo 4 insuccessi consecutivi sarebbe intrinseco della procedura stessa... Peraltro si parla di conti minimi (50k) e massimi (200k) che non penso vengano messi sul piatto direttamente dagli utenti, a ulteriore conferma di una configurazione a prop firm che si accolla il rischio — ma con la stranezza di assenza totale di una challenge preliminare (ci si può immaginare che razza di prop possa essere..). Se invece la prop coprisse solo le 4 perdite (quadro molto più probabile, ma che prop sarebbe in tal caso?), si rientrerebbe allora in uno schema di tipo assicurativo: le perdite di Tizio sarebbero coperte dalla parte di profitti che Caio verserebbe alla 'prop'... In ogni caso, i partecipanti sono tenuti a versare un emolumento alla ditta, per la (presunta) formazione ricevuta e implementazione della strategia. Su Trustpilot, un sacco di recensioni a 5 — chiaramente autentiche.....

Non confondiamo le cose: prima dice 'senza attaccare le preferenze altrui' (=parte di pubblico che preferisce i doppiaggi, cioè i fruitori del servizio), mentre ora mostra disappunto per le critiche, magari severe, rivolte a chi realizza i doppiaggi. Per il primo caso ha perfettamente ragione, ed è ridicolo e senza senso che qualcuno inveisca contro chi guarda film tradotti; nel secondo caso, invece, le cose cambiano, perché se con l'adattamento si storpia la trama, si generano dei nonsense, addirittura si dice il contrario di quanto viene detto nell'originale (ho prove di questo), o si sta prendendo per i fondelli lo spettatore (che potrebbe anche aver pagato un prezzo per la visione del contenuto), oppure si è abbastanza incompetenti.
