Description
Technical field
The invention belongs to the technical field of ship cooling system, more particularly to a kind of marine engine supplement heat rejecter water interior circulation
System and cooling means.
Background technology
The effect of ship cooling system is the equipment high-temperature heating parts such as cooling diesel engine so as to which temperature is maintained at effective
In working range.On the following medium and small-scale vessel of light-draft kiloton, cooling system is usually arranged as：Two are arranged in cabin
Sea chest is arranged in two sides of a ship, is connected by a seawater main, and on seawater main, the left and right side of a ship is respectively provided with a sea water filter,
Isolating valve is set before and after each sea water filter；Two kingston valves of the left and right side of a ship either alternatively or simultaneously can be used, and clean one of filter
When do not interfere with the normal supply of sea water；Main frame sea water pump sucks sea water from seawater main, is delivered to main frame, gear-box, tailing axle
Discharge after pipe, exhaustor；The sea water of discharge divides three tunnels, and a road goes out outboard via main exhaust bank of tubes, and a road is via tailing axle bank of tubes
Go out outboard, another route topside outlet discharges outboard.But as the beam of the following medium and small-scale vessel of kiloton is little, drinking water
Shallow, hull cabin section section lines are V-shaped, and according to code requirement, main frame Sea Chest need to be arranged in two sides of a ship, must not be arranged in ship
Near midship, therefore main frame Sea Chest position is inevitable higher, close to waterline, causes the winter in northern cold cold junction ice, floats over water
The ice wadding in face is easily from main frame Sea Chest suction ship.When ice wadding flows through the filter on seawater main with sea water, due in filter
Portion's mesh is intensive, causes ice wadding blocking filter.Find in real ship application：Ice wadding blocks the speed of filter quickly, at short notice
Occur that main frame sea water pumping does not go up the too high phenomenon of water, main frame temperature, main shut-down system is forced, after need to manually removing filter ice wadding
Can reset；And it is breakneck that ship is shut down in stormy waves.In order to solve the following medium and small-scale vessel of kiloton tight
The cold weather short time is unable to supply the problem of cooling water, we in the urgent need to a kind of novel cooling water internal circulation system, as normal
The emergency power of rule cooling water system.

Specific embodiment
In conjunction with accompanying drawing, embodiment of the present invention is illustrated, the invention is not limited in following embodiments.
As shown in figure 1, a kind of marine engine supplement heat rejecter water internal circulation system, including ballast tank 1, the going out of ballast tank
The mouth of a river is connected with 2 import of seawater main by outlet pipe 8, and seawater main outlet is by water inlet pipe 9 and the cooling water inlet of main frame 3
Be connected, the coolant outlet of main frame is connected with discharge outlet by drain pipe 11, the water return outlet of ballast tank pass through return pipe 10 and
Drain pipe is connected.Also include water replanishing device, water replanishing device includes ballast water tank water 4 and ballast pump 5, ballast water tank water passes through filling pipe 21
It is connected with the water supplement port of ballast tank, ballast pump is on filling pipe.
Outlet pipe is provided with the first stop valve 12 and thermometer 20, and water inlet pipe is provided with the second stop valve 13, on return pipe
The 3rd stop valve 14 is provided with, on filling pipe, the both sides of ballast pump are respectively equipped with the 4th stop valve 15 and the 5th cut-off along water (flow) direction
Valve 16, drain pipe is provided with the 6th stop valve 17.Ballast tank located at underwater with sea water directly contact.
High-speed craft typically arranges plural ballast tank, and is arranged symmetrically with regard to hull centrage two-by-two.In order to
Make that cooling water internal circulation system pipeline is as far as possible short, interior circulation cooling water use time is tried one's best grows, should choose that cabin of disembarking is near, capacity is big
Two ballast tanks being arranged symmetrically as interior circulation water tank, ballast tank should be arranged underwater, and direct with sea water
Contact, to ensure that the heat in time in severe winter cabin interior circulation cooling water can be taken away by outboard sea water quickly, reaches good radiating
Effect.The outlet of ballast tank should be disposed adjacent to ballast tank bottom position, and water return outlet should be disposed adjacent to ballast tank
Tip position, and outlet and water return outlet should try one's best away from, with ensure high-temperature tempering in cabin sufficiently cool mixing after recirculation
Cooling main frame.Ballast water tank water is arranged near hull center line face.
After interior circulation cooling water system is opened, as sub-fraction cooling water can pass through exhaustor cooling jacket 18 and tail
Outboard discharged by central siphon cooling jacket 19, and therefore the cooling water in ballast tank can be gradually decreased.When discovery thermometer displays temperature
During more than 32 DEG C, ballast pump should be opened and sea water is injected to ballast tank.In order to prevent ballast pump suction strainer by ice wadding blocking, should
Ballast water tank water is arranged near hull center line face, is absorbed water here deeper, it is not easy to which suction floats on the ice wadding of the water surface.
The workflow of this cooling system is：When the filter 6 of two side of a ship of seawater main is by ice wadding blocking, before and after closing filter
Isolating valve 7, close the 6th stop valve that is provided with of drain pipe of main frame, at the same open the first stop valve, the second stop valve and
3rd stop valve, now the cooling water input main frame in ballast tank, cools down to main frame, is then transferred back to pressure from return pipe
Water tank is carried, and cooling water so circulation is finished up to filter cleaning, when thermometer displays temperature being found higher than setting value, is opened and is pressed
Pump, the 4th stop valve and the 5th stop valve is carried, and sea water is supplemented to ballast tank until thermometer shows from ballast water tank water suction sea water
Temp. displaying function is less than setting value.
Due to the limited volume of ballast tank, when therefore replacing external dynamic sea to supply water to main frame with ballast tank, ship should
Lowsteaming in holding, can so make water temperature in ballast tank be unlikely to rise too fast.In order to determine the suitable speed of a ship or plane, Ying Lie
Go out per platform main frame sea water pump maximum stream flow with corresponding relation between engine speed, ship speed, as shown in the table：
| Engine speed (r/min) | Ship speed (kn) | Per platform main frame sea water pump maximum stream flow (m3/h) |
| 1800 | 22.0 | 65.4 |
| 1596 | 20.0 | 59.76 |
| 1200 | 15.6 | 43.62 |
| 1015 | 13.1 | 34.32 |
| 900 | 12.0 | 30.9 |
| 750 | 10.0 | 25.68 |
In order to good radiating effect is reached, should ensure that the cooling water inflow of main frame suction at least 0.5 hour is not more than two
The total moisture storage capacity of individual ballast tank.If set two propulsion main frames per ship, two ballast tank total measurement (volume)s are 30m3, then as seen from the above table
Engine speed should be down to about 1000r/min, and the speed of a ship or plane of ship is about 13kn.
Prove through ship sea trial, meeting an urgent need in severe cold weather enables novel cooling water internal circulation system, can replace routine
Cooling water system supplies main frame short-term operation, it is ensured that main frame is not shut down, so as to solve the following medium and small-scale vessel of kiloton in severe cold
The weather short time is unable to supply the problem of cooling water, it is to avoid the danger that ship is shut down in stormy waves.
The above, be only presently preferred embodiments of the present invention, not makees any pro forma restriction to the present invention, this
Skilled person makes a little simple modification, equivalent variations or modification using the technology contents of the disclosure above, all falls within this
In bright protection domain.
