The

cooling

system is of forcible

circulating

water-cooled

type,

see figure 12 for detail.

The cooling system

contains

radiator,

water pump, fan, heat

retainer,

air

guide

cover and etc.(diesel

engine

without

air

guide

cover

and

radiator)

Cooling liquid in

the

radiator

delivered

water

channel

water

pump,

and

then

enters

into

the

surrounding of the

cylinder sleeve and

last flows into cylinder header by the cylinder sleeve. The used cooling liquid returns to

the radiator through heat retainer at the front of the cylinder head and the outlet pipe.

The heat retainer closes when the temperature of the water flowing out is less than

℃

, and the cooling liquid flows into inlet pipe of the water pump through a small

circulation on front plate of the cylinder, then it flowed into the water pump a second

time to realize a small circulation; when the water flowing out is 70

℃

～

℃

,the heat

retainer opens, and the cooling liquid flows into the header tank of the radiator through

the heat retainer, and flows into the lower tank through a flat copper pipe. During the

process, the cooling liquid is cooled by the drafting or exhausted by the fan. Up to now, a

big circulation is completed. Air drafting or exhausting is adopted for the fan as required.

Water pump is a centrifugal type. The water pump is driven by fan belt surround the

shaft belt pulley. During use, if the water backfill is damaged, which leads to serious

water leakage in the lower part of the water pump, please change a new one. Do not

clock the water backfill if it is damaged, otherwise, it may enter into the bearing and

accelerate abrasion of the bearing. If some unusual noise be heard when bearing

operates, it should be changed. As the “Technical Maintenance” required, the

calcium-radical lubricant will be added to the Oil cup of the water pump regularly. The

lubricant should not be added more than 1/2

～

1/3 of cavum of the bearing, otherwise will

cause the bearing hotness. Hot retainer is a rival pipe and single valve type, contains

liquid sensitive to temperature which can auto control the valve’s operation.
