What Is Diesel Generator Antifreeze Solution And Its Function
by Starlight Generator dieselgeneratortechThis article mainly talks about Yuchai diesel generator antifreeze solution and its function. If you are interested, take a few minutes to read it.
Currently,
water is widely adopted as the cold - medium of the water-cooled engine,
including hard water and soft water. River water, well water, spring etc.
enrich water with the mineral material as hard water, being subjected to hot
empress the mineral quality sink wall to become water dirt in water set with
spread the hot machine, dying down diesel engine to spread thermal energy dint,
the serious hour will appear an um of set and live cold wreath to chafe, the
piston choked to death. But the water tank knot dirt hereafter will cause the
water temperature go up and open a pot.
Therefore
must use the soft water as the anti - freeze. The in common solution of
transferring the hard water into soft water is to boil hard water to removes
sediments. The more exhaustive method is to add to soften in the hard water,
such as adding 0.5 baking sodas of ~ lg(
pure alkali) or the 0. 5-0. 8 g hydrogen to oxidize NA ( caustic soda).
There is
much weakness using the water as the anti - freeze.
1) it is
easy to,become water dirt.
2) 2) the
freezing point of water is an 0 ℃, it is easy
to freeze a jelly crack an air cylinder body and spread a hot machine easily in
winter.
3) 3)The
boiling point of water is 100 ℃, because
the machine widespread adopt technique of turbo - charger, the normal water
temperature is 105 ℃s for 95℃s, will
usually appear to open a pot in summer.
4) 4) The
cooling system is sewn a medium soldering by six kinds of metals iron castings,
aluminium, steels, red coppers, brasses and the water tank to constitute,
water, imply water of miscellaneous quality especially, as to its have a
corrosion function, appear rusty with cave eclipse phenomenon.
As having
been overcome many disadvantages of the water - coolant, the anti - freeze
solution becomes the ideal coolant which can be used in each season of the
year.
1. What is
anti -freeze solution?
Anti - freeze
solution is a coolant used in winter to prevent frostbite. It has a long
history. At the first time, people added the inorganic salts into the water to
lower the freezing point or raise the boiling point; then the organic alcohols
(such as ethanol, methanol, etc) were added further. And in the recent years,
the anti - freeze solution has developed to become the glycol and glycerol
based anti - freeze solutions. But for the price reason, the application of the
new developed solutions was restricted. Nowadays, it is the glycol based anti -
freeze solutions that have been accepted widely.
Anti -
freeze solution is made up of raw alcohol, water and additives. The alcohol is
glycol and the water is distilled water. The additives include antitrust
agents, anti - toxicity agents, PH regulating agents ( buffering agents) , and
other agents, and other performing enhancing chemicals.
2. The five
functions of the high quality anti -freeze solution
A. Anti -
corrosion
Anti -
freeze solution contains a system of excellent and lasting corrosion inhibitor,
which achieve certain balance with the metal through various agents and form a
protection film on the metal surface; moreover, it can strip the existing
corrosion on the cooling system to prevent further corrosion. Tests show that
qualified anti - freeze solution can be 50 to 100 times less corrosive to metal
compared with water.
B. Anti
cavitations
Cavitations are formed by numerous foams
impinging the metal. Tests show that hard waters containing salts and bases are
several dozens faster in its cavitations speed compared with that of clean soft
water. While anti-freeze solution does not contain hard water, and the anti -
foaming in it can inhibit the production of foams.
C. High
boiling point character
The boiling
point of anti - freeze solution is usually at 105℃ ~110℃, even higher than that of water.
D.
Anti-scaling character
High quality
anti - freeze solution is made from the distilled water and it contains anti -
scaling agent, hence it does not produce any scale.
E. It has
the following characters:
1)Superior
anti - freeze performance
2)Anti -
corrosion and anti - rust
3)Non -
swelling or erosion on the rubber seal guide.
4)Preventing
scaling of the cooling system.
5)Anti -
foaming.
6)Low
viscosity at low temperature.
7)Stable chemical properties.
