Engine is the soul of a
vehicle and without it, your car or motorcycle will just be a structure made of
metal and other materials. If the engine will not work properly then the
chances of breakdown drastically increase. Imagine that you are on way for work
and the engine stops working halfway. This can be a terrible situation for you,
especially when you are going for an important meeting. Therefore it is
crucially important that the engine of your vehicle is hale and hearty. In
order to avoid breakdowns it is advised to go for engine servicing at regular
intervals of time. Apart from this, it is also essential to use good quality Oil Lubricants and additives for
running the engine. The quality of fuels and additives that you will use in
vehicle’s engine will immensely affect its performance. Therefore always opt
for good quality fuel and additives that are formulated after extensive
research.
Fuel Additives
Diesel Oil that you are adding to
the engine of your vehicle is not enough for maintaining and running it. You also
need good quality fuel additives to reduce abrasion and friction in moving
parts of engine. Apart from this, fuel additives also help in preventing
corrosion of engine’s metallic components. Additives play a very important role
in keeping the engine in good functional state for long time. Diesel engine
fuel additives also help in preventing engine breakdown during adverse
environmental conditions.
Synthetic Diesel Engine Oil and Its Advantages
Synthetic oil is made by artificially amalgamating natural and chemical
products. This formulation is quite beneficial for the working of engine and it
provides resistance against oxidation, sludge and thermal breakdown. Diesel
engine synthetic oil is formulated to efficiently perform at extreme functional
temperatures because it remains balanced at extremely low and high
temperatures. This oil has better shear and chemical stability in comparison to
the traditional diesel engine oil. This factor makes it excellent for vehicles
which work in severe climatic conditions. This Engine Oil reduces the evaporation loss in diesel engines, and
increases fuel economy. It is also more economical in comparison to
counterparts available in market. Synthetic oil also reduces the initial drag
on the engine which boosts the horsepower and torque on vehicle’s engine. It is
engineered to offer superior fortification from deposit formation on hot spots
of engine. Synthetic oil also reduces the probabilities of blockage caused by
gradual build-up of deposits. It also lengthens the drain intervals, which
decreases the generation of waste byproducts by engine. There are many more
factors that make synthetic oil good for vehicle’s engine and investing on it
is certainly a lucrative deal.
Statistics show that up to 70% of
all damage caused by pollution of the hydraulic system or debris inside the
system. Any professional engineer knows that the purity of the Hydraulic Oil - is the key to long-term
operation of hydraulic machines. But cleanliness - it's not all. It is equally
important to choose the correct hydraulic fluid and replace properly. This is
what we will talk today.
General recommendations
In order
to select hydraulic fluid two options should be considered. First - ambient
temperature during operation. Second - the viscosity of the fluid in the
working temperature range. The second parameter is specified in the instruction
manual of each individual machine. Some sources state that the viscosity of the
hydraulic fluid depends on the type of pump that is used in the system. This is
not entirely true. The viscosity at operating temperature is calculated based
on the bandwidth of the narrowest channel in the hydraulic system, as the
hydraulic fluid must have a certain rate of flow through these channels,
otherwise hydraulics will not work correctly. Thus, for many construction
machines, using the same models of hydraulic pumps different types and brands
of hydraulic fluid are often used. For example, in modern hydraulic excavators,
so-called "proportional" valves with very small cross section of the
channel are used. The system is quite complex, with electronic control
components. If you choose the wrong viscosity of hydraulic oil for the system,
the machine will not operate at full capacity. Accuracy or operations speed may
reduce. The recommended oil type is usually indicated in the cockpit on the
special information labels or directly to the tank of the hydraulic system near
the filler neck. Today the modern machinery often recommends using high
viscosity grade oil HVLP. This is hydraulic oil with
a more modern package of additives than in oils class HLP. Oils of this class
have more stable viscosity-temperature performance, and in severe cold
conditions they work better. Manufacturers of these oils indicate the
temperature range from - 30 to + 60 degrees Celsius. In addition to stable
temperature characteristics of oils of this class possess multifunctional additives
to improve anti-oxidation, anti-corrosion, anti-wear, depression, water
separation, anti-foam properties of the liquid.
In winter and summer...
Hydraulic oil should not be used year round. Especially when it
comes to second-hand machinery. In pumps with a high degree of wear of the gaps
between the friction parts are bigger. If the winter oil is used and a viscosity
at strong heating becomes very low, the pump performance will decrease
dramatically. The oil pumped will simply spill out between the plunger and the
pump casing. This reduces not only the pump efficiency, but also the pressure
in the system. Using winter fluid in summer may lead to lubrication failure of
the pump due to its low pumpability. This is especially true in the equipment,
which is equipped with powerful hydraulic pumps (cranes, concrete pumps,
excavators, etc.). Some "artisans" to reduce the viscosity of the
frozen oil pour into the hydraulic system a certain amount of diesel fuel. This
leads to very disastrous consequences. The fact that when the hydraulic system,
despite the presence of antifoaming oil additive in the hydraulic fluid air
bubbles are formed. With heavy use oil boils. If oil is present in the fuel,
the inside of bubbles is almost ready fuel-air mixture. When compressed oil in
the hydraulic cylinders occurs absolutely the same process as that in the
diesel engine: in vials mixture under pressure ignites and rapidly destroys
hydraulic cylinders. Skilled, repair hydraulics, at dismantling the cylinders
quite often come across melted seal - this is the result of the addition of
"Diesel Engine Oil" in the
oil.
The rules of the Workers
'hygiene'
Instructions for replacing the hydraulic fluid are provided by
almost all machinery manufacturers. Unfortunately, not everyone reads and
comply with them. Let me remind you the basic rules. The oil must be stored in
clean closed canister. Before pouring fresh oil from the hydraulic tank, remove
all the dirt that has settled in it for the last few months of operation. Oil should be poured in clean
containers only. Hydraulic systems have to refuel oil pump, not fill. In this
case, the likelihood of dirt from the surface of the container into the system
is greatly reduced. Filling the hydraulic system should be through the filter,
since the purity of the liquid even in the original container does not always
meet the requirements of hydraulic equipment. The oil which is contacted with air
cannot be stored for more than two years. If it turned out that it had to be
drained from the hydraulic system, which has not had time to work out its term
(this often happens at various breakdowns hydraulics), then before you pour it
back it does not hurt to analyze its characteristics. It is not too expensive.
When it comes to heavy equipment with large gas volumes, this procedure is
justified.
