Хорошее видео. Понравилось то что в видео есть всё. Продемонстрирована сборка. Продемонстрировано испытание. Также ты проверил до какой глубины хватает давления. Даже добавить нечего. Нравится !
I see a lot of half-arsed DIY videos, but this one actually shows some knowledge. It's the little things, like roughing up a surface before gluing, or properly measuring the stroke, and even testing the results properly, that make for some quite impressive videos.
RU-vid suggested this for me so I watched it and gave this project a try. I made some of my own modifications and I think I could actually use this to make a crude airbrush setup. Instead of using silicone for the membrane pieces, I used pieces of a normal party balloon. I also cut a hole in the top of my chamber and siliconed another balloon in the hole so I would have a bit of a reservoir. Overall I'd say this thing is pretty decent for low volume low pressure stuff.
Really nice project. I've done something like that about 12 yrs ago and that worked too. I got improvement for You: Removing blades in fan rpm are increase and probably current consumption should go a little bit down.
Cool man. You might wanna use it to make copper acetate to do copper e-plating. Drop something like copper sheet...etc. inside white vinegar in a jar and let that bubble on it until it turns blue.
Halo saya dari indonesia saya ingin mengucapkan terima kasih banyak karna ide anda sudah membantu saya dalam membuat solder uap menjadi berhasil dan oksigen buatan untuk aquarium saya nanti.👍🎉
Я сделал за 1 минуту!!! Кулер от обдува процессора с ноута. О.5 л бутылка ПЭТ. Натянул на прямоугольный выход. Зажигалкой нагрел бутылку и буквально запаял бутылку в кулер. Подал от зарядки мобилы 5 вольт и поставил переменный резистор для регулировки скорости кулера. Всё. Подача воздуха для новой самоделки термофена готова.
Dear friend, Pierre! It was very pleasant to read your message. Thanks for the feedback! If you have any ideas, I will be happy if you share them. Maybe there's something I can do. Or watch my channel. Along with the usual video there will be many more interesting ideas. Have a nice week! :) Alex
Nice and neat, but the performance could be improved. Your cylinder is too large, relatively to the travel or stroke. The large volume of air inside compresses and that's why you get only 10cm of 'depth'. Try stuffing the chambers with something solid like balls to take up as much volume as possible leaving paths for the air and try
Do you know what's the output in liters/minute and how noisy it is comparing to genuine aquarium air pump (provide the brand and model name you've used for comparison)? I want to swap my noisy air pump as silencer box I've made doesn't help enough (want to eliminate noise as much as possible).
Автор, а если дополнительно сделать камеру для вентилятора с выходом на впускной клапан? Конечно производительность +- такая же, а вот сила насоса увеличится. Как идея?
Не совсем понял) Если производительность будет такая же, то не имеет смысла. Крутящий момент кулера слишком мал. Из всех написанных комментариев я понял, что нужно сделать маленькую рабочую камеру и поставить другой мотор.
It is important not the number of revolutions, but the torque of the motor. To force the water column, it is important to have a number of amps in the cooler. It takes a lot of effort to overcome the resistance of the membrane. The greater the depth of immersion of the tube in the water, the more forces must be applied to the membrane. Better 1 amp and 1000 rpm than 0.5 amperes and 2000 revs. Do you understand me?
hey bro hi i am new at this work and i dont know from where do i buy this thing like some battery connector or fans like this can you say me from where did you buy that things and i love to do like this work thanks your video was awesome sorry for bad English its my third language lool
The simplest and most effective to buy a new device. If you want to do yourself, then you need to consider some of my mistakes. I did everything from scrap materials. Buying only the connectors and silicone used to make membrane. All links you can see in the description. Motor is better to take more powerful, even if it will be less rpm, but the torque should be higher, so he could easily move the membrane. A conventional computer fan is very high speed, but little torque, so it is sometimes not enough effort to overcome the resistance of the membrane. I hope you understand me. The working chamber should be as small as possible. Ideally, the amount of incoming air must be equal to the amount of escaping air. If it is a good motor, it is possible to increase the stroke of the piston. This will allow for 1 cycle to pump more air. These are the basic guidelines. Good luck!
I bought it at a local store in Russia. "Super moment, maxi volume, universal second glue". I want to try to order this one on AliExpress, it is very similar: ali.pub/1genfn
а скорость вращения кулера влияет на производительность? и будет ли лучше с оборванной крыльчаткой? или использовать воздушый поток от кулера каким либо образом?
В данном случае скорее нет, чем да. При увеличении расстояния между рабочей камерой и кулером, производительность насоса падает в ноль, а кулер начинает бешено вращаться. При сближении ход мембраны увеличивается и он начинает работать отлично, но возрастает нагрузка на кулер и так как он не рассчитан на большой крутящий момент, может остановиться. Думаю без лопастей будет лучше. Кто-то предлагал использовать воздушный поток для охлаждения аквариумной лампы) или что-то наподобие)) Всё же я рекомендую использовать другой мотор, который выдаёт бОльший крутящий момент. Именно момент тут намного важнее, чем обороты.
Buenos días, si usas un cooler pequeño y un embudo del tamaño del cooler y una manguerita del tamaño de la salida del embudo funciona mejor y mas rápido el hacerlo...
To increase pressure fill the space somehow behind the membrane. Now you have a very small displacement with a very big cylinder. In best case the two volumes almost the same. Then only the motor will be the limit. :-)
