Okay, guys so I’m in the process of restoring this machine for a friend… It not old and has low hours but the previous owner never did any sort of maintenance to the burner at all! Ran it til it stopped working.
Its a 12 Volt Beckett burner.
The issue is, after a few minutes of operating at full heat the burner drips raw oil. Not very much but not okay! I don’t think it’s a broken coil because drip only starts once the burners on and has a couple minutes of run time, once burner is turned off the drip quickly stops
New electrodes
Transformer has good spark
Blower Fan Is moving air well
New Nozzle Installed, Correct size and angle
New Diesel Filter
Fresh Diesel
New Water Separator Filter
The oil (beckett clean cut) pump seems to have good pressure set at 140psi as it should be. (needle on gauge flickers but I have a cheap pressure gauge not oil filled)
Valve Solenoid seems to cut fuel on demand… As it should… Checked the Ohms and it checked off fine.
Flow Switch seems to be working on/off
I think the problem is after drip, once I let the gun off I think some dripping of raw oil happens… But I can’t figure it out.
No black smoke, some light white smoke after the trigger is released hence why I think its (after drip)
We have a new pump and solenoid coming in tomorrow, and see if that works…
If it’s white smoke, then you have too much air intake. You can sometimes tell that if, when you squeeze trigger, there is a pause and then a boom when it ignites.
Try adjusting the discs until there is no smoke after trigger is released. It may solve the problem.
The white smoke happens after the trigger is released, not while the burner is burning. After the trigger release it will puff some white smoke, but not very much but it is noticeable.
Yes, I replaced it with a new delavan nozzle and filter. The correct one 90 B Degree 1.75
I even went as far pulling the burner out and killing the spark to watch the nozzle spray, and I did notice a problem!
The 90 degree nozzle spray was hitting the F/22 blast tube head, its a real wide angle on that 90 degree spray pattern, pushed up some just so the spray angle would clear, put it back in and dripping continues.
I will post a pic of the blast tube head before I pushed the gun out a little further. You can see that the spray nozzle has been hitting the blast tube head, its sooted up real good.
@Chesebro i was thinking about this this morning on the side of the fuel pump you should have a inlet and a return. Take the return line off the tank run it into a bucket im thinking that your return line may be clogged.
Check the line and the pump discharge. If that’s OK change you flow switch it may be sticking and allowing enough power for the pump to pull fuel for a few seconds after
So I’m working on her now and I just noticed the burner is coming on with no pressure. Machine is off and has no water pressurizing the flow switch! That can’t be right.
All I can think of, is the flow switch isn’t sending a clean on/off command… and the Solenoid valve bleeds fuel thru… then the drip happens
The by pass hose is clear! No obstructions in the hose.
BUT, I’m not sure if it’s normal. When I have the burner on the ON position (not burning mode but just on) I look inside the diesel tank and look at the bypass Return and it stops and goes it doesn’t bypass continuously like an unloader valve by passing to a buffer tank when off the trigger… shouldnt it by pass continuously?
