Model Marine - New Engines from China
« on: December 29, 2012, 05:06:08 am »
One of the interesting things here is that the steam regulator is mounted PRIOR to the lubricator  >>:-( <*<
 
By convention, most manufacturers [Stuart, JMC, ANTON, SAITO, ACS, etc...etc] mount the lubricator on the discharge side of the boiler & hence all components [including the steam regulator] in the steam line are lubricated  O0
 
From the setup below....an additional M8x1 female socket and an M8x1 male nipple would appear to resolve this...however this new manufacture may have an alternate engineering concept???????? .........Derek

After seeing this I went to Ebay and found it was currently at $795 Aus and a buy now of $995.

Looks like more cheap shoddy goods from China. The lubricator is probably mounted where it is due to ignorance rather than sound engineering principles.....

I wonder if they're following prototype practice which puts the lubricator after the throttle.

They say something similar about those speed controllers that burst into flames as soon as you give them any work to do....

Hello! :-)

the steam regulator is mounted PRIOR to the lubricator

This is mounted this way , when the boiler has no shut off valve,in order to avoid the oil to be sucked back in when cooling down.
But, as those regulators are not designed to seal properly, anyway, I guess that it does really matter!
Let's wait until some one tells us more about this engine! ok2
Cheers! :}

Hi KBIO......compliments of the season to you O0 .....
 
The detail on the engine was copied from the Australian importers WEB page below...he also displays Maccsteam boilers naturally with the boiler isolation discharge valve.......
 
I have alerted the importer of the question to the location of the lubricator......he has acknowledged my communication
 
In fairness, I suggest that the engine looks to be of impressive design, however the importer may need to build an open launch.....fit it with the engine & Maccsteam boiler & provide a VIDEO under steam for all to see
 
Happy boating & steaming for 2013  :-)) .........Derek

Hi PD's....the Australian importer http://modelmarine.net...is offering a 5"horizontal boiler for US$1285.00 when in fact it is the Mccsteam 5"boiler for 715.00 GBP = US$1156.00 ........their WEBSITE acknowledges these are Maccsteam products

In reality the price differential is OK, as it would be approx AUD$100.00 to air ship the boiler from UK to OZ......

No ...just checked a private consolidated air freight source UK to OZ .........

6kg and the parcel being 400x200x200=...............AUD$191.64............... Derek

I prefer to have the lubricator after the regulator, like Saito, Aster, Hemmens, MH&B and others.
I don't want oil in my boiler.

If the lubricator is before the regulator wouldn't you end up with the steam line full of oil should the engine be stopped / regulator closed for an extended time with the boiler 'live'?

Mike...if the engine is stationary there is no steam flow....therefore no displacement of oil into the steam line.....
I do understand that different manufacturers have differing thoughts on this........Sandy Campbell from ACS Engineering drummed it into me that steam regulators are mechanically loaded devices & what better way than to keep the valve faces lubricated was with a fine mist of steal oil in the passage
Posssibly one of our experienced model steam engine builders [ooyah/2......George are you there?]  may wish to comment ..............Derek

Took a lot of explanation and rending of teeth and gnashing of hair to a mate who had more than forty years experiance in live steam toy locos how the displacement lubricator works. Still not sure he believes it.

Flow is not required, or very little. As long as the lubricator has live steam on it some will continue to condense and displace oil - into the pipe.
Unless my understanding of a displacement lubricator is horribly wrong.

Most lubricators have a needle valve, once this is screwed fully home, no steam can condense in the oil, weather there is a flow of steam or not, I always use this type of lubricator regardless, as oil consumption can be  controlled.....

Derek,
In my opinion it doesn't matter where the lubricator is situated, I have been running a steam plant  for the past 12 years with a Scotch marine return flue boiler 4.75" in dia feeding a D10 and due to lack of space the lubricator is after the steam regulator and I have never had a problem and the steam comes to the regulator after passing thro' a steam dryer in the fire box of the boiler which is very hot, I have never had any oil contamination in my boiler.
I do have a shut down valve on the outlet of the boiler but most of the time I forget to close it.

The loco boys have a regulator at the end of the boiler at the smoke box end and they feed oil into the line after the regulator to no ill effect.

I am at present having a rest from building a Minnie traction engine and the engine saddle is bolted directly to the boiler with the steam coming up thro' the outside of the piston wall to the regulator and then into the steam chest and a feed will have to be taken to lubricate the valve all off this before the lubricator.

I do feel that some of you guys get into a bit of a twist over such minutia, as long as you have a lubricator, preferably with needle control, stick it anywhere.

I don't have a very high opinion of this new engine , as has been pointed out by John, one standard is different from the other at the base, so if such a fundamental error has occurred here what else is lurking in the engine.

HAPPY NEW YEAR TO ALL
 George.

Very similar engine to the Mildura. The mildura is a great piece but very pricey.

Here's one with two lubricators, one for each cylinder but after the throttle!
