Embodiment Construction

[0015] The present invention will be further described below in conjunction with accompanying drawing.

[0016] see figure 1 , dry dock cooling water system debugging method of the present invention, comprises the following steps:

[0017] Step 1, using pipelines to connect the water inlet valve on the dock door, the pump unit and the seabed door of the ship. That is: set several water inlet valves on the dock door of the dry dock, use branch pipes and butterfly valves to connect the water inlet valves and pump sets, and use branch pipes and butterfly valves to connect the pump sets to the ship's seabed door. The cooling water pump of the pump unit is installed at the bottom of the dock close to the left and right sides of the dock door, that is, installed below the lowest liquid level to ensure that the river water can flow into the pump cavity by itself.

[0018] Step 2, use river water as the cooling water source, and introduce the cooling water into the ship's seabed doo...

Abstract

The invention discloses a debugging method of a cooling water system for a dry dock. The debugging method comprises the following steps: 1, communicating a water inlet valve on a dock gate, a pump set and a ship sea chest through a pipeline; 2, introducing cooling water into a ship sea chest through using river water as a cooling water source; and 3, introducing heated cooling water into the discharging main pipe through the outboard discharging pipe, then discharging into the in-dock water collecting well through the discharging main pipe, and finally discharging into the river through the water discharging pump. And the wharf mooring time of the cruise ship can be greatly shortened.

Description

technical field [0001] The invention relates to the technical field of shipbuilding and debugging, in particular to a method for debugging a cooling water system for a dry dock. Background technique [0002] At present, in the process of large-scale ship construction in China, the system debugging related to cooling water is completed in the wharf stage and sea trial stage after undocking, and no debugging is carried out in the dock stage. This requires additional procedures. If it can be debugged in the dock stage, it can greatly reduce the mooring time of the cruise terminal, arrange sea trials as early as possible and reduce the trial cycle, thereby effectively saving time and cost. Contents of the invention [0003] The purpose of the present invention is to provide a cooling water system debugging method for dry docks, which can greatly reduce the mooring time of cruise ships. [0004] The technical scheme for realizing the above-mentioned purpose is: [0005] A met...
