I’m running a DN 15 flowpro with a 2.1 mm orifice 3/8 Bullet proof chemical injector. Cold water machine
I noticed when pulling chemical through the injector the soap mix would come out as warmer water. Then when I would rinse, the water would be cool again.
Any ideas why the fluctuations in temperature of the water? It consistently does this. I’m wondering if the pump is producing too much heat.
Off trigger Time and Bypass is never more than 30-60 seconds max.
I see no one has answered, my guess is it just has to do with you not using a buffer tank and the bypass circulating through the pump and heating up.
Tell us more about where your soap mix is coming from. I batch mix mine and have it in a 15-gal drum in the bed of a black pick up truck. After sitting out all day the contents in the drum are definitely warmer than the water coming straight out of the spigot of the home. I’m using a direct drive with no buffer tank.
Also worth noting, if you haven’t discovered yet, that if not using a buffer tank, the water that’s sitting in the system while you are off the trigger will be warmer for a few seconds once you get back on the trigger. For my set up - which usually is running through 150-ft of 3/8” pressure hose - it takes about 14 seconds for whatever is at the pump to come to the pump end of the wand. So if I’ve been off the trigger for 45-60 seconds and then pull the trigger it’ll take approximately 14 seconds after the trigger is pulled for that water that is flowing through that hot pump to start to come through the gun/wand. It’ll stay warm for perhaps 4 or 5 seconds then it’s back to “cool” tap water temp. @dcbrock was eluding to all this in his above response.
what Brock said no bypass water does get fairly warm.
Friction produces heat, 9th grade science class. Back then the teacher used to demonstrate on a student by rubbing a student’s forearms with their hands quickly while applying some pressure. Now they would probably be arrested, but I remember it to this day.
Those were the days. We got to play with mercury in our class. The Tesla coil was cool too.
I’m running all of this through a 10 gallon per minute pump with a bypass hooked up to a 200 gallon buffer tank.
I’m running 100 feet of half inch hose tapered down to 100 feet of 3/8 inch hose
I can pull the trigger all day long and that soap still feels warm.
Soap is coming from a designated tank 20 gallons. No bleach mix. Just soap.
When I switch my flow pro from calling for soap to rinsing, the water goes cool again.
Have you taken a meat thermometer and actually measured anything to see the actual difference or does it just feel warmer. What soap are you using? Do you use a 3-way valve going into injector to rinse it?
