Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to an air removing device for a pump,

The present invention relates to an air removing apparatus for a pump, and more particularly, it relates to an air removing apparatus for a pump, which is capable of smoothly discharging air generated in a pump and a suction pipe when a draft of the vessel is located above the pump, The present invention relates to an air removing apparatus for a pump which can shorten the starting time of the pump even when the pump is started.

The ship is equipped with a ballast system to adjust its draft and trim. This type of ballast system generally consists of a number of ballast tanks installed on the hull and a ballast pump for supplying and discharging ballast water (seawater) .

Fig. 1 is a schematic view showing an example of a conventional ballast system of a container ship, and Fig. 2 is a schematic diagram showing an air / overflow discharge line of the system of Fig.

As shown in the figure, the conventional ballast system 110 of the container vessel 100 includes a double bottom ballast tank group 121 and a hull outer wall 102 disposed horizontally on the bottom 101 of the ship 100, A plurality of (e.g., two) ballast tanks for supplying and discharging ballast water to each tank of the ballast tank group 120, a ballast tank group 120 including the vertically disposed side ballast tank group 122, A piping system 140 connected between the ballast tank group 120 and the ballast pumps 130 and the offshore seawater and having a plurality of on-off valves 146, and a group of ballast tanks 120, Overflow discharge line 150 for discharging ballast water, which is installed between all the tanks of the tank and the upper deck 103 of the vessel and overflows with air contained in each tank of the tank group 120, out of the tank, As shown in FIG.

In such a conventional ballast system 110, the piping system 140 is connected to two kinds of tank groups constituting the ballast tank group 120, that is, a double low ballast tank horizontally positioned below the sea surface 104 Both the supply and discharge of the ballast water to both of the group 121 and the side surface ballast tank group 122 vertically positioned above and below the sea surface 104 are entirely performed by the ballast pumps 130. [

That is, as shown in FIG. 1, two main lines 141 having branch lines 142 for each tank are piped between the entire ballast tank groups 120, The two pumps 130 are connected to the two pumps 130 through a plurality of connection lines 143, 144 and 145 so that all the two pumps 130 are connected to the ballast tank 120 for all the tanks in the ballast tank group 120 It is configured to be used for water supply and demand.

Therefore, when supplying the ballast water to the ballast tank group 120, the ballast water sucked through the suction line 147 by the two pumps 130 is supplied to the double low ballast tank group 121 and the side ballast tank group 122, The ballast water in the ballast tank group 120 is supplied to the double bottom ballast tank group 121 and the side ballast tank group 120 even when the ballast water is discharged from the ballast tank group 120, Is discharged outboard via the discharge line (148) by the pump (130) without distinction of the discharge port (122).

In this way, each piping system 140 can be configured so that each pump 130 receives ballast water for all tanks without appropriately sharing the supply and demand of ballast water to the tanks of the ballast tank group 120. [ Which is intended to enhance the efficiency of the pump 130.

In such a conventional ballast system 110, one of the biggest problems is an air / overflow discharge line (hereinafter, referred to as " air / overflow discharge line ") having a function of discharging the air inside the tank and a function of discharging the overflow of the ballast water out of the tank 150) should be installed for all the tanks of the ballast tank group 120.

That is, as described above, in the conventional ballast system 110, since the supply of the ballast water to all the tanks of the ballast tank group 120 is entirely performed by the pump 130, At the same time, an air / overflow discharge line 150 for discharging excess supplied ballast water out of the tank must be installed for all the tanks of the ballast tank group 120.

However, the configuration of the air / overflow discharge line 150 installed in each tank may be such that the diameter thereof is at least 1.25 times the diameter of the branch line 142 of each tank (e.g., 200-250 mm) And the end at which the air and the overflow are discharged should be at least 450 mm or more in height at the upper deck 103 of the container vessel 100. In order to comply with these regulations, There have been various problems in designing and drying of the apparatus.

One of the problems is a problem related to the arrangement of the air / overflow discharge line 150 to the upper deck 103, the hull structure and the shape. That is, since the air / overflow discharge line 150 in the container ship 100 is disposed in a narrow space between the side passage space of the hatch coaming of the upper deck 103 and the hatch coamings of the lateral direction, There is a problem that hatch coaming must be reinforced when a large-diameter drain hole for draining an overflowed ballast water must be installed in the hatch combing portion.

Another problem is that the air / overflow discharge line 150 is penetrated through the upper / lower deck 103 so that the air / overflow discharge line 150 penetration method, penetration position, It is necessary to pay close attention to the strength of the hull.

Another problem is that when determining the numerical value regarding the durability of each ballast tank considering the position of the air / overflow discharge line 150, the reference of the head height of the air / The strength of the hull must be adjusted accordingly.

Conventionally, when the draft of the ship is located above the ballast pump, an air ejector is used for the pump or a self priming unit is used to remove the air generated inside the suction pipe or the suction pipe, .

In this case, since an air ejector or a self-priming device is used in the pump to remove the air in the pump, an air line, an electric cable, and an expensive priming device are required, which complicates the structure and increases the cost .
