Keeping your model steam engine and boilers in good working order is important
for obvious reasons. This is not really particularly difficult it is more a
question of making the effort to do it. Attention to good lubrication is a good
starting point, lubrication is essential for almost all mechanical mechanisms,
take the time to study and research the lubrication requirements of your
particular engine it can make a big difference to the performance and life of model steam engines.
Boilers generally don't need a great deal of
maintenance, providing distilled water is used then there should be no deposits
of calcium to contend with, calcification is one of the worst enemies of
boilers the buildup of lime scale can block pipes in worst cases and also acts
as internal insulation which will adversely effect the performance of the
boiler. This can be removed retrospectively with the use of a weak or dilute
acid but be very careful as acids may well adversely attack the materials the
boiler is made from, commercially available kettle de-scalars can be a good as
generally they are gentle and sympathetic to metals.
Where ever possible follow the manufactures
guidelines when it comes to care and maintenance if unsure then contact them if
possible.
Below are some steps you can
follow to enhance the life or your models.
Dismantling; the pros and cons
As a general rule
it is not good practice to start dismantling engines and boilers unless you
have a good understanding of the subject, it is quite often the case that
innocent tinkering can result in more problems than you started with. A good
first step is to contact the original manufacture if this is possible and ask
their advice, if this is not an option then member's of clubs, and there are
many, can often offer assistance and guidance.
Cleaning
Cleaning your engine frequently is good
practice, firstly it will keep it clean and maintain its appearance and
secondly it is a good way of detecting any wear or other issues that may be
evident. Hot water and detergent is probably the best way of removing oil and
dirt from components, solvents should be avoided as they can attack seals
within the engine and may in extreme cases affect any paintwork present. Tooth
brushes and cotton buds (Q-tips) are a good way of getting into those hard to
reach places.
Lubrication
Good lubrication is essential for any
mechanical device and particularly so for the steam engine as some parts of
steam engines operate a high temperatures and require specific oils, a model compound steam engine for
instance as a number of cylinders operating at different pressures and
therefore different temperatures. Oils for cylinders often have additives which
enhance their performance at high temperatures and pressures. On the other side
of the coin parts of the engine will remain quite cool and can safely be
lubricated lighter oils such as just plain motor oil.
This is some very basic guidance on how to
care for model steam engines which
it is hoped will be both informative and useful.
