The scale and dirt in the cooling water
collects at places where the water flow is slow, and
lowers the cooling effect.
In extreme cases, it may even block the water line.
Corrosion resistors act to suspend the magnesium and
calcium, which are the main components of scale. In
this way, they prevent the scale from sticking to the
liner heads. In addition, the corrosion resistors form
a hard protective film on the surfaces in contact with
the cooling water. This prevents direct contact by air
bubbles with the liners, and the liner heads from corrosion.
The fuel also acts to lubricate the injection
pump. The injection pump and the injection nozzles are
machined to extremely high precision. If there is any
dirt or moisture in the fuel flowing through the injection
pump or nozzle, it will cause seizure of the injection
pump or clogging of the nozzle. The fuel filter removes
this dirt or moisture, and supplies clean fuel to maintain
engine performance and extend engine life to the maximum.
If the engine sucks in the dust in the
air, there will be serious wear of the cylinders and
piston rings which will result in lack of power and
black exhaust smoke. At the same time, it will cause
other problems such as high oil consumption. The air
cleaner acts to filter out this dust, and to provide
clean air to the engine, thereby maintaining engine
performance and also extending engine life.
The engine oil acts to lubricate, clean
cool, and seal the rotating and sliding parts of the
engine. If there is any dirt or water in this oil, there
will be abnormal water or seizure of the piston or bearings.
The oil filter removes this dirt and moisture to enable
the oil to carry out its role properly, thereby maintaining
engine performance and extending engine life.
Hydraulic filters are the filters used
in the torque converter, transmission, steering, and
hydraulic circuits of the machine. The feature of these
circuits is that the pressure and oil temperature are
Hydraulic filters act to remove the metal
particles caused by wear of the sliding parts in the
torque converter, transmission, and other parts of the
power train, together with wear particles from the lining
inside the steering and brake circuits, and the dirt
and dust in the circuit. In this way, they ensure that
clean oil is sent to the valves and actuators.
In these circuits, the oil passes through
small orifices, and the oil pressure is finely adjusted,
so clean oil is essential.
