Oil Pump

Post by Gez » Thu Jan 08, 2009 5:44 pm

Just finished my first turbine based on a turbo and gave it a test run today, however the pump I was using for the oil was struggling due to the viscosity of the oil, my dad suggested thinning the oil with some diesel, would this be ok in a jet engine?

Also I noticed what appeared to be some burning oil dripping out of the engine at one point, is this normal or is something broken?

Hi.

Some use a Shurflow pump, that tolerate oil. Myself I use an Ford Escort mk 1 oilpump driven by a 24 volt lawnmover engine at 12 V.

Thinning the oil is a bad idea. Use 0W30 oil instead.

The dripping can be many tings. PM racketmotorman he is the guru wrt. Gasturbines.

Hi Gez

With regards your burning oil drips, what can happen is that during storage or static testing of the lube system , oil seeps into behind the heatshield at the turbine end , it works its way down and out thru the joint as the heat comes on , helped along by the static gas pressure rise of the running engine , resulting in drips of burning oil ,..............its happened to me on occassion after lots of lube system testing , but once the engine is being used normally , it shouldn't happen again unless the oil seal is in bad condition and allows oil to bypass it during cooldown motoring of the engine with the lube pump operating .

Cheers
John

I used a Power steering pump from a Toyota coupled with a Radiator fan motor and a small grooved belt .. Works well.. It was too strong actually i was getting around 100psi out of it so i had to make a bypass valve to lower the pressure.
