Hey guys, i need some help from you by explaning the ratio of the chemicals, i have read and searched for videos and havent found much, but inhave a few doubts. When it says 40:1 ratio what does that mean?. Does it mean that 1 gallon of the chemical is for 40gallons of water? Or is it the same 1 liter of product in 40 litters in water?.
Now another doubt, i downstreamed 1 litter of product with the black nozzle and i filled a bucket of 8 gallons, does that mean that the ratio is 1 liter for 8 gallons? Can i dilute the product and then downstream it so that i can use less and save some money?..
2: 1 gal =approx 3.8 liters so would be 3.8 times 8 gal = 30.4 - 1. That’s a pretty weak ratio. Most 8gpm will pull 20:1 and smaller machines even stronger. What size is your ds injector and machine?
Just do this.
Bucket#1. Fill a 5gl bucket using your black tip, write the time down.
Dump the water, divide it by 60.
Bucket#2. Now use another bucket and fill it up with water, put your injector hose in.
Bucket#1. Fill a 5gl bucket but using your chemical injector, write down the time, divide by 60.
Look at your bucket#2 and see how much you used.
Now you have your ratio.
It only says 2.1 and has an arrow pointing out, my machine is a 4000 psi 4.3 gpm and the injector does not have a screw to regulate the flow. And still dont understand the ratio!.
To understand the ratio please see @Racer post and read it carefully he told you your ratio is 30.4 : 1 so: your machine will pull 30.4 liters of water from the water source per 1 liter of chemicals through the DS injector.
That 2.1 that is having you disoriented is probably the orifice size, that tells you it’s ratings, and yours with 2.1 orifice is rated for 3-5 GPM machines, so it’s rated for yours, but smaller orifices than rated seem to draw more than rated.
That arrow you said it’s (pointing out) you guessed it, tells you the direction the water should go through, (out)
No entendi lo de dividirlo entre 60 . Lleno una cubeta y checo el tiempo q tarda en llenarse, ese tiempo lo divido entre 60. Despues la segunda cubeta la lleno de agua y le pongo el inyector y cuanto el tiempo que tarda en vaciarse, y ese tiempo lo divido entre 60. Asi es como lo entendi. El numero que resulte de la division que es?
If you buy a Chemical Injector with that draw rate 45:1, then you have even lower suction percentage to water, lower chemical draw then the one you have at 30.4:1.
I’m glad if I helped, you’re the first one I’m trying to help in pressure washing field/forum I’m newbie and learning as well, I don’t have a business yet, and even have 0 equipment and experience in practice, but it feels good to be able to help someone.
typical house wash mix you want ( Low as possible that will still clean) for me its between .6% - .75% On dirtier houses might have to bump on to 1% ( those numbers are final amount of SH hitting the siding). So if your using 12.5 % SH and your draw is 40-1 then your drawing around 0.3% SH.
Oh ok i get it!, so you buy a DS injector according to the ratio you need. Oki get it now haha. Dont worry i am new as well, i had been wanting to start a pressure washing business here in my city in mexico and after two years i bought a used 4gpm 4000 psi beldriven pressure washer , i want to do fleet washing cause house washing here is difficult cause people dont want it. But thanks your info helped me, i also need to find the good chemicals for two step washing.
Thanks for the information sir, here in mexico is hard to find that equipment, i want to start fleet washing but the soap recomendations come in ratio and i didnt understand how it worked. Thanks!
Es para saber cuantos galones por minuto.
El segundo balde con agua donde el injector va llenalo con agua 5 galones.
Prende tu maquina, usa la boquilla negra, y llena un balde de 5 galones.
Cuando se llene, para y mira cuanto has usado en el balde del injector.
No tienes que usar quimico, con agua basta.
Asi sacas el promedio de quimico que usas.
En realidad el ratio no importa
Si te parece fuerte, mezcla el quimicoo con jabon y anade agua.
You have to choose your DS injector according to the highest chemical draw/suction rate that you might need out of the gun, because, to lower it (the concentration) you can, as you mentioned earlier you can easily dilute chems first and then downstream, but you cannot make it stronger than its rated draw rate is, it will draw that much and not more, nor you can make the chemicals stronger then you buy them as opposite to dilution which you can.
