For at ryde misforståelser af vejen bliver denne på Dansk. Jeg har 2 tryklamper. Første opklarende spørgsmål, er det korrekt at anvende lampeolie i disse ? eller er der et bedre alternativ ? 1. en Primus 1020 X-19 mærket, så den er ret gammel, som jeg forstår det (et arvestykke...) men burde nok kunne komme til at lyse, pt. virker den noget fed i blandningen, ny nål og dyse fra fogas isat... jeg skal have kigget til tætningen på drejeknappen, den har en lille lækage, når der kommes tryk på. Den holder tilsyneladene fint tryk men grisser glødenettet delvis til og lyset er ikke imponerede... 2. En Petromax Rapid 829/500CP -11 takker i stjernen, hvilket vist gør den til en Kineser-udgave, den er enormt fed i blandning, skal man bruge tid på denne lampe / delene i den, eller er de så ringe/dårlig kvalitet, at de bør udskiftes, jeg tænker udfordringen formoddentligt ligger i "forgasningsringen" ? jeg kan læse mig til en del har kæmpet med at få dem til at virke efter hensigten - Pt. har den fået en ny dyse og nål. Som det sikkert, blandt kendere/brugere af disse lamper ses, er jeg begynder på området, men vil gerne lære at få dem til at virke så godt, som de kan og bør... Fordi, man kan og legetøj som ikke virker er mere eller mindre værdi løst... ;o) Med venlig hilsen, Henrik And in an Google translation: To clear up misunderstandings, this one will be in Danish (mostly becourese of the fuel question) I have 2 pressure lamps. First clarifying question, is it correct to use lamp oil in these? Or is there a better alternative? 1. a Primus 1020 X-19 marked, so it is quite old as I understand it (an heirloom...) but should probably be able to light up, currently. it seems a bit oily in the mixture, new needle and nozzle from fogas inserted... I must have looked at the seal on the knob, it has a small leak when pressure is applied. It apparently keeps a fine pressure, but partially clogs the filament and the lights are not impressed... 2. A Petromax Rapid 829/500CP -11 fails in the star, which probably makes it a Chinese version, it is hugely fat in the mixture, do you have to spend time on this lamp / the parts in it, or are they of such low/bad quality that they should be replaced, I think the challenge presumably lies in "loop vaporizer, Preston Loop."? I can read myself to some extent have struggled with getting them to work as intended - Pt. has it got a new nozzle and needle. As you can probably see among connoisseurs/users of these lamps, I am a beginner in the field, but would like to learn how to make them work as well as they can and should... Because you can and toys that don't work are more or less worthless... ;o) Best regards, Henrik
Welcome aboard Henrik! Lamp oil is best used with wick lamps, proper paraffin / kerosene is the fuel for the two lanterns which you have mentioned and they are preheated with meths / alcohol. I always completely dismantle lanterns and thoroughly clean every part and your two lanterns have the non return valves / NRV.. located in the bottom of the pump tubes and a special tool is required to remove those valves. We never know what fuel a previous owner has used so it's best to give the tanks a good clean out too. Photographs of your lanterns will help us to assist you. There are several Danish members of this forum and perhaps some of those live in your area. The links below show relevant paperwork, but the library is only open to subscribers. https://classicpressurelamps.com/th...fin-kerosene-lantern-petroleum-laterne.21665/ https://classicpressurelamps.com/threads/1935-primus-1020-instructions.8954/
Hi jeff, Thanks. I know the preheater, in Danish the product is called "Husholdnings sprit" translates to sometinhg like "household-spirit" it's a product used i cleaning glass and mirrors and ofcourse in alcoholburners, like in a "Trangia" Camping-cooking ( if you know them) or similar... And for the kerosene/paraffin names... I think lamp-oil is the same product in Denmark, but that was the actual reason, for using danish as language at first, to be sure there is no misunderstanding, what product is what, so to speek... I havent found an, i my opinon, translation in other places... Pictures will come, one of the day's...
Hello Henrik, some of the other Danish members will be better able to advise you on which fuel to purchase in Denmark and yes, I have heard of Trangla stoves.
Hi Henrik and welcome to the forum. Both your lamps should be able to work well. They obviously need looking at as there is obviously something not quite right. If you need any advice you are welcome to get in touch directly. A private message in Danish is fine. As far as fuel goes, what I use is "Heatmax gold" from Harald Nyborg.
Hi Nils, Thanks, HeatMax, as i see it, is eqvalent to Qlima-Extra ? (jem&fix / bauhause) -i have some of that.... And yes, they both need some care and internal cleaning, no doubt. Wonder about the petromax, knowing it is chinese, is it, can it be, or be made, as reliable as the older german made, or is it more or less a waste of time ?
Hello Henrik, I have found that the Chinese Petromax clones will work well once they have been thoroughly cleaned and properly set up.
Petromax 829.. in parts, cleaning time... Primus, waiting for cleaning... And just a little question, what size mantles should fit "the little Primus" -it looks like it is probably a bit smaller CP wise ? Best regards, Henrik
Hello Henrik, The Primus is a 300 cp.,(candle power) lantern so it does need an equivalent sized mantle and it best to use a bulbous style of mantle rather than the sock style of mantle, a bulbous mantle will form closer to the vapouriser / generator and therefor keep the vapouriser hotter, which means that the fuel will vapourise properly, the mantle which is shown in the photo has formed to far away from the vapouriser.
Hi Jeff, It was what I would consider a bulb-style, named Veritas 3890 300/400CP -but perhaps, I should try to unfold it a litle less, next time I try to lite it... -when it has been gone over with an internal cleaning...
The mantle on the 1020 looks ok to me. Maybe not enough pressure when forming, but not too bad. The mantle you mention is the right one for a 1020. Lets see how it goes when you get back to it.
Today's picture, "The china-max on fire".... Well, more like, with a light in it, after cleaning, burning a lot better, i think... mantle is From Fogas bulbstyle....... It look's like there is a bit of burn outside on pictures, but in live action, it is almost not visible, perhaps even less after a while of lighting, a bit hard to tell, it is blinding me ...... - is that normal? the way it burns... - I do know that it should blind me ;o)
It is quite normal for a new mantle to take some time (~30 min) to settle in. If the light is blinding, then it is working correctly.
Tanks, did noy know, they could be that long to settle... A friend asked me, how old is this lamp ? The "China-Max" - is there a way to tell? not that it mater much to me personal, I think The Primus from 1933 is a bit more exiting, also becourse it was my grand fathers, so it has some personal relation value to me...
