outlets on the thermostat: one is connected to the radiator and the other to the
inlet of coolant pump which is also called as short circulation. When coolant
hits 80±2
℃
, the thermostat begins opening and is fully opened with coolant
at 95
℃
. In such case, all the coolant after flowing though the radiator for
cooling will be pumped into cylinder block. However, when the coolant is
less than 80±2
℃
, thermostat will cut off above mentioned passage, making
the coolant directly go into the inlet of coolant pump and accordingly heat
the engine rapidly until the required thermal state is reached. Therefore, that
can prevent the wear at low temperature and prolong the useful life of diesel
engine. In case of coolant pump leaking, replace its seals. Before delivery of
diesel engine, the oil chamber of coolant pump has already filled with 120cm
all-purpose lithium-base grease for vehicles that should be refilled
periodically.
5.5. Use and maintenance of starter
a.
Starter, as short-time working part, should work for 15s at most every
time. In addition, the starting interval should be more than 30s.
b.
In winter, if ambient temperature is less than 5
℃
, preheat the engine
before startup.
c.
Release the starting switch the moment the engine is started, separating
the drive gear of starter from the gear ring of flywheel.
d.
Do not power the starter until the engine stands still, which can prevent
the flywheel from impacting the starter gear.
e.
The installation of starter must follow its wring drawing. Before
removal of starter, ensure the battery is disconnected from the starting
wire of starter.
f.
Frequently check whether the fastener and wire insulation of starter are
damaged, and whether the wire is well connected. In addition, remove
the dirt.
5.6 Use and maintenance of generator
a.
Rational matching: with engine idling, the generator should meet the
electricity consumed by all the electrical equipments. The generator
mismatching the electrical equipments could lead to lack of electricity
in battery and generator overheating that could resulting in damage to
governor and stator burning. Generator should have proper min. running
rpm, because too-low working speed (determined by the engine idling)
