Problem solenoid oil burner

[aerialcastor]

For your pressure regulator it is necessary to check that the small piston slides freely in its bore.

Freely it's not too much the word.
Must still force a little to push it.
I will dismount and see that.

1) pre-purge the combustion chamber for 10-20seconds. (If a flame appears during this time, the burner will be safe). There is also precompression of the pump to 3-5bars and often (but not always) ignition of the electrodes.
2) opening of the magnetic valve, mounted at operating pressure 10-15bars (depending on settings), and firing the fuel oil.

It looks like what I have.


I have no flame, it is not likely there is no oil outlet nozzle.


Detail that may have been important: the failure happened just after the firefighter valve was inadvertently dropped

As for the auto gauge, a test beast:
return 5L of gasoline to the tank; if it starts, it's because the gauge is kidding

The test was done it does not work better

The test was done it does not work better

So gasoline, all good, gasoline that arrives in the carburetor (smell), all good, there is only the ice cap in the muffler !!!!
Test, warm up in garage and the next day, start with plenty of water flowing out of the pot !!


Look if the firefighter valve does not have a hidden security vault ??? direct or indirect reactivation ??????????????????????????????????

If the pressure goes up to the mano, it must also go up to the pump output.
To check:
-the tube between the pump and the nozzle may be clogged.
-The nozzle is clogged

Detail that may have been important: the failure happened just after the firefighter valve was inadvertently dropped

Or because of this, the pump compresses (puts the pressure) but has no more power (no flow at the pump outlet).

I did not have time to look today if it was going well. It will be for tomorrow.

The jet is not clogged it's on.
And I am using a bottle to avoid the air vents.

It's very enigmatic.


What is very surprising is that if I set a low pressure with the regulator, the fuel comes out.
If I serve the screw little by little at a time there is no more oil coming out.

hello I had the same problem on the boiler of my parents-in-law it was the micro filter of the injection pump which was clogged following a tank filling that had taken off the mud from the bottom of the tank

[aerialcastor]

It can be that.

In fact we have to add a few liters of fuel oil from a can in the tank, it has certainly well brewed.


Does the room change alone?
And how much does it cost?

[dedeleco]

Watch if these sludges are not soluble in petrol and commercial fuel solvents, or acetone, gasoline F, etc.
Because by letting it soak a day with agitation, blowing air or petrol under pressure in the opposite direction could we unblock it ?????
I have already done this on other filters or ink jet printers.

[aerialcastor]

The filter in question soaked at night in WD40.
In general it is very effective but no.
And it's nothing to push into the other without Karcher apart, but I'm not sure that sending water is a good idea, and not about sending 12bars

[dedeleco]

A bicycle pump makes 1 at 2 Bars with plastic hose !!
We never know???
An 12 Inflator on 12V Tire makes 3 at 4 Bars ?.

A test is to see if the oil passes a little in the filter by pushing with the pump and shaking by blows or aspiring !!
So we know if it's clogged or not with certainty.
Try without the filter ??????

Have you removed the BTR screws called pressure taps (4 and 5) on the diagram?
On the pump I was talking about, there were 3 or 4 BTR screws to unscrew and the flange (it says "suntec" on yours) was removed. A small o-ring was falling out and there was the small filter in a hole. After removing it with a rag and clean fuel oil and it's settled.
