I know it is not a model, but it is not very big.
I have a very old Perkins P3 in excellent condition, and I am trying to connect it up to drive a 65 Kw 3 phase Alternator, to get about 10 Kw in my workshop to drive various 3 Phase devices. I have a 3Hp 3 phase converter but it is not man enough to drive my lathe at full speed and the immitation 3 phase does cause problems with a preoptive3 phase motor that does the speed changing
To start with I tried to mount it in-line with a flexible coupling drive, but this meant that the engine had to be mounted too high on the bed. Also I followed advice and installed cushyfoot resilient mounting pads as well. The end result did drive ok, but the engine jerked about a lot and appeared to be in danger of damaging either itself or the coupling. The next step was to lower the engine so that the flywheel did not foul the sides of the channel on which it was mounted, and use a v belt drive with identical A size pullies. The 4 inch mounts to get the engine above the base are U section and may not be rigid enough as I still feel that it is moving from side to side excessively and I am reluctant to run it full speed (1500 rpm).
I am told that this old engine was not very well balanced, but how should I proceed? Let it vibrate on flexible mounts or strengthen the mounts on either side to try and stop the vibration. I could use some4" square section I have and box in the ends, that would make it a lot more ridgid, or put in welded cross pieces, across the bed. Is this the way to go? The end result should be as quiet as possible, and run on biodiesel
I have a 40 Kw set with a 4 cylinder Lister air cooled engine where the engine is directly mounted on the frame which is as substantial as mine, that I made and it runs very well, I could use it instead, except 1. it is air cooled and I want to harvest the waste engine heat and 2. it is very noisy and 3 it produces a lot more power than I actually need.
Has anyone any productive ideas or suggestions about this, - if so I would be glad to hear them.
Thanks a lot George.
