Flow.
As shown in Fig. 2, when refuting operation on shifting ship, ship is gradually moved to from the bank on floating dock, to make floating dock keep water
Level state, a part of cabin need outboard to drain, and a part of cabin may need the water filling into cabin.For different ballast tanks,
The ballast water capacity of injection or discharge is different, and is changed constantly, according to the size of upper barge oceangoing ship and distribution of weight, shifting
The factors such as speed, tidal level rate of change are refuted on ship to be calculated by computer simulation correlation model.Due to valve regulated flow
Limited ability, especially for bigbore butterfly valve, in the case of changes in flow rate range is larger, only pass through valve regulated
Words are unable to reach requirement, and operation difficulty is big, and control accuracy is low.And the operating point of pump can be caused to deviate specified work by valve regulated
Condition so that the efficiency of pump reduces.Therefore the embodiment of the present invention is directed to the operating feature that lower water partly latent is refuted, and variable frequency pump is selected to make
For ballast pump, control station is refuted speed and tidal level rate of change according on the size of upper barge oceangoing ship, distribution of weight, shifting ship, is generated each
The data on flows of ballast tank, and the frequency variation signal of the corresponding variable frequency pump of each ballast tank is generated according to the data on flows,
The flow of ballast pump is controlled by adjusting the frequency of pump.By the adjusting of frequency, the efficiency of pump is not only unaffected, and
And operation power can decline to a great extent as frequency reduces, and play energy-saving effect, and can cut operating costs.

It is determined according to the quantity of ballast tank and the quantity of pump room.Fig. 5 is illustrated by taking the pump room of left side as an example, and each pump room is arranged two
Ballast pump, every ballast pump control two ballast tanks；The ballasting system of starboard pump room and the ballasting system of larboard pump room are symmetrical
Arrangement.
When moving ship operation, shifting ship top surface and the harbour top surface of lower water partly latent barge are maintained at same plane, lead at floating dock
It crosses ballasting system and prestowage is carried out to the water in ballast tank.When being refuted due to moving on ship, a part of cabin needs outboard to drain, one
Subdivision may need the water filling into cabin, and required flow is different according to different operating modes.Water level inside and outside cabin when being refuted on shifting ship
Difference relatively can may influence the effect of gravity feed.If water level is absorbed water higher than external in cabin, will be unable to realize into cabin
Continue to inject.And the flow of gravity feed is difficult control, therefore ballasting system shown in fig. 6 cannot achieve as lower water partly latent
The function of refuting.
When floating dock sinks, the manifold valve in topside injection valve and each cabin is opened, since there are water levels inside and outside ballast tank
Difference, external water utilize flow by gravity water inlet ballast tank；When floating dock is floated, injection valve is closed, opens manifold valve and discharge header
On dump valve, start ballast pump, the water in ballast tank is drained by outboard by ballast pump, the ballast pump in pump room can have
Standby functions each other.If wherein 1 ballast pump breaks down, can be arranged using other 1 ballast pump by opening coupling cock
Water.Conventional floating dock is to reach sinking or the floating at floating dock by injecting or being discharged the ballast water in the ballast tank of floating dock
Function.When floating dock sinks, since there are water-heads inside and outside ballast tank, usually realized using flow by gravity water inlet.Floating dock
When floating, the water in ballast tank is drained by outboard by ballast pump.
In floating operating mode, all ballast pumps are opened simultaneously at floating dock, the ballast water in cabin are discharged, therefore institute in Fig. 6
The ballast pump shown usually selects main frequency water pump that can meet the requirements, and the water of different ballast tanks can be by manifold valve
Valve is adjusted, however when water if you need to adjust entry/exit ballast tank, it can only be adjusted by branch pipe valve aperture regulation
Precision is poor, and not easy to operate, and efficiency is low, not energy-efficient.
