Method, it comprises the steps:
Step one, verifies the refrigerated sea water flow needed for generating set motor-car and pressure according to refrigerated sea water system diagram；
Step 2, is caused the sea water in fire main pipe on wing wall or building berth by aqueduct in the seawater main on ship,
Fire main pipe is provided with fire pump；
Step 3, causes in ballast tank by ascending pipe by the sea water in seawater main, makes ballast tank deposit necessarily
The sea water of volume；
Step 4, causes the suction side of the cooling sea water pump of generating set by drain pipe by the sea water in ballast tank；
Step 5, will affect other shipment valve closing that above step normally works；
Step 6, starter-generator group, the cooling sea water pump of generating set draws water to sending out from the ballast tank depositing sea water
In the cooler of group of motors, the cooling freshwater system with generating set carries out heat exchange, opens the fire pump on fire main pipe simultaneously
Mending sea water toward ballast tank, the turn-on flow rate of fire pump is more than or equal to the turn-on flow rate of the cooling sea water pump of generating set；
Step 7, during motor-car, the ballast tank liquid level of sea water is deposited in monitoring in real time, by fine setting fire main pipe
The turn-on flow rate of fire pump makes ballast tank maritime interior waters be maintained at certain liquid level；
Step 8, through the sea water of subcooler, in being directly discharged to depressed place or the drainage system of building berth, or guides to pipeline
Other storage area or flow back in the sea.
As currently preferred technical scheme, the top of described ballast tank is provided with permeability cell.
As currently preferred technical scheme, in described ballast tank, level monitoring device is installed.
Implement the method that the ship launching leading sea water of the present invention moves electromotor in advance, compared with prior art, have
Following beneficial effect:
1., before the motor-car of generating set being advanced to ship launching opportunity, fulfil construction node ahead of schedule；
2. the motor-car generating of generating set is equipment or the debugging wound of system that other electricity system requires high (as needed 660V electricity)
Make precondition, whole pier mooring debugging cycle can be shortened, directly produce great economic benefit.
Accompanying drawing explanation
In order to be illustrated more clearly that the technical scheme of the embodiment of the present invention, the accompanying drawing of embodiment will be situated between simply below
Continue.
Fig. 1 is that the present invention draws sea water under dock construction state and moves the piping arrangement schematic diagram of electromotor in advance.
Detailed description of the invention
Below in conjunction with the accompanying drawings and embodiment, the detailed description of the invention of the present invention is described in further detail.Hereinafter implement
Example is used for illustrating the present invention, but is not limited to the scope of the present invention.
As it is shown in figure 1, the preferred embodiments of the present invention, a kind of method that ship launching leading sea water moves electromotor in advance,
It comprises the steps:
Step one, verifies the refrigerated sea water flow needed for generating set motor-car and pressure according to refrigerated sea water system diagram.
Step 2, causes the seawater main 3 on ship by the sea water in fire main pipe 1 on wing wall or building berth by aqueduct 2
In, fire main pipe 1 is provided with fire pump 4；Wherein, the caliber of aqueduct 2 needs to meet the accounting requirement of step one, aqueduct 2
Upper installation valve 5 and Pressure gauge 6.
Step 3, is caused the sea water in seawater main 3 in ballast tank 8 by ascending pipe 7, makes ballast tank 8 deposit
The sea water of one constant volume；Wherein, the caliber of ascending pipe 7 needs to meet the accounting requirement of step one.Further, described ballast tank
The top of 8 is provided with permeability cell 9, thus, makes the air pressure inside of ballast tank 8 equal to ambient pressure by permeability cell 9, prevents
The air pressure inside of ballast tank 8 changes in sea water injection process and affects seawater pressure and discharge stability.Described pressure
Being provided with level monitoring device 10 in carrying water tank 8, this level monitoring device 10 deposits the ballast tank 8 of sea water for monitoring in real time
Liquid level.
Step 4, causes the cooling sea water pump 12 of generating set 11 by drain pipe 15 by the sea water in ballast tank 8
Suction side.
Step 5, will affect other shipment valve closing that above step normally works.
Step 6, starter-generator group 11, the cooling sea water pump 12 of generating set 11 is taken out from the ballast tank 8 depositing sea water
Water carries out heat exchange to cooling freshwater system 14 with generating set 11 in the cooler 13 of generating set 11, opens fire-fighting simultaneously
Fire pump 4 on house steward 1 mends sea water toward ballast tank 8, and the turn-on flow rate of fire pump 4 is cold more than or equal to generating set 11
But the turn-on flow rate of sea water pump 12.
Step 7, during motor-car, ballast tank 8 liquid level of sea water is deposited in monitoring in real time, by fine setting fire main pipe 1
The turn-on flow rate of fire pump 4 make ballast tank 8 maritime interior waters be maintained at certain liquid level, be sure not too high or too low.
Step 8, through the sea water of subcooler 13, in being directly discharged to depressed place or the drainage system of building berth, or draws with pipeline
To other storage area or flow back in the sea.
In sum, the method that the ship launching leading sea water implementing the present invention moves electromotor in advance, on the one hand, will generating
Before the motor-car of unit is advanced to ship launching opportunity, fulfil construction node ahead of schedule；On the other hand, the motor-car generating of generating set is
Other electricity system requires that precondition is created in the high equipment of (as needed 660V electricity) or the debugging of system, can shorten whole pier mooring and adjust
In the examination cycle, directly produce great economic benefit.
Below it is only the preferred embodiment of the present invention, it is noted that those skilled in the art are come
Saying, on the premise of without departing from the technology of the present invention principle, it is also possible to make some improvement and replacement, these improve and replace also should
It is considered as protection scope of the present invention.
