IV. Brief introduction on engine room arrangement The boat engine room is at stern part
Generally, main engine and gear box are between frame 7#~12#, through sterh shaft to drive 4-blade fixed pitch ducted propeller, stern shaft bearing is water lubrication.the boat has shaft bilge pump and DC shaft generator.
Navigation power equipment: main engine is from Weifang Diesel Engine Plant, model: TD226B-4C1,it can meet the design requirements of speed and towing tension. main engine is installed between frame 8#~12#.
Output device at main engine front-end: main engine front-end output through V-belt pulley to drive sea water cooling pump; bilge pump and engine front-end are connected with winch in front of engine through elastic coupling, to drive winch to work.
Output device at main engine back-end: main engine flywheel end is directly connected with 135 type gear box, gear box output coupling is rigid connected with intermediate shaft coupling, intermediate shaft is rigid connected with stern shaft system through coupling.gear box operates clutch through hydraulic system,
to control propeller forward, stop and reverse.
Main engine cooling water equipment:closed cycle cooling, fresh water cooling pump attached to main engine drives fresh water cycle cooling, fresh water inside main engine cycling is cooled by sea water through heat exchanger.
Main engine lub. oil equipment: main engine itself has engine oil pump, engine oil filter and so on as a completer system, which can finish engine oil cycling. engine oil cycling tank for lubrication oil is installed in engine room, it can be added into main engine by oil bucket while needed.
Main engine fuel equipment: main engine fuel system includes fuel supply pump and filter attached to itself, and daily fuel tank and manual pump installed in engine room, fuel is pumped into daily fuel tank through manual pump, than fuel is flowed into main engine from daily fuel tank.
V. Power pipeline introduction:
Fuel pipeline: main engine uses light diesel oil, fuel tanks are installed on portside and starboard, after pipeline is connected, fuel is pumped to daily fuel tank by manual pump, then flowing to main engine through fuel filter and fuel pump. daily fuel tank has sectioning valve, can be used for draining oil and other use.
Cooling water pipeline: main engine cooling pipe uses closed cycle type.system inside cooling is done by sea water, through heat exchanger. Sea water is sucked into pipeline by sea water pump from hull valve, going into cooler first, then entering gear box engine oil cooler after being cooled, then going to heat exchanger above main engine after being cooled, and then being discharged outboard by pipeline after cooling fresh water. what’s more, there is also sea water emergency inlet branch in pipeline, for emergency use.
Fire & drain system: the system has one general pump for both fire and draining.
Bilge water system: every fish hold has one sewage-sucking in tap, engine room has two sewage-sucking in taps, through transforming of stop check valve, both bilge pump and manual pump can be used for pumping sewage water everywhere, it also has sea water guiding system.
There is one removeable pump as for spare pump of fire and bilge pump.
