Shipbuilding - submarine valve of sea water filters - bottom door screen
Seabed gate filter for shipbuilding - Sea chest for shipbuilding
Directly through the seabed gate filter, seabed gate sea water filter AS350 CB/T497-1994
Marine water filter for ship right angle seabed gate, 350A CBM1061-81 of a roughing water filter at the right angle seabed gate
The necessity of maintenance of seabed gate filter - sea water filter for seabed gate:
The door itself is leading to the outboard seawater valve in the cabin, the sea water pump through which the water sucked for machinery, ballast (adjust ship balance) and the crew's life and some other purposes. Sometimes because of rust caused by water in ship cabin it sank, so he Wuxiu is the focus of inspection and maintenance of the object.
The location of the sea water filter in the cabin of the engine room:
The seabed gate is an open sea channel for sea water extraction, controlled by one or two large valves. It is usually divided into high seabed gate and low seabed gate. So we need to install two seawater filters to form the cabin high sea level door, sea water filter and engine room low level sea gate filter. Sometimes, according to the design of the ship, we will add an emergency submarine door seawater filter.
There are high position submarine doors and low sea level doors in the engine room, emergency fire emergency seabed door filters, oil tanker, ballast sea gate and seawater filter in cargo hold area, FIFI special sea gate filter with OSV on external fire fighting system.
Selection criteria for marine filter for marine seabed gate:
CB/T497-1997 seabed filter, marine filter for marine seabed gate
High seabed gate filter, marine low seabed gate sea filter CBM1061-81
JISF-5K/10K diurnal canister sea water filter, ballast seabed sea water filter
The layout and inspection of the sea water filter for the seabed gate of the ship's engine room:
The door is only hull plate with a hole for sucking outside seawater or fresh water (in the river), the other side opening basically for emissions.
The seawater inhaled from the submarine door is used to cool low temperature and fresh water. During the good voyage, the high and low seabed doors can suck clean seawater, and the low subsea gate's water temperature is relatively low, which is conducive to the energy saving of the cooling system.
When ships are sailing in shallow waters, the use of high seabed doors and seawater filters can inhale relatively pure seawater, so as to avoid sediment and other impurities enter the system and block up filters. Large ships may design multiple high level sea gates and seawater filters.
In addition, in the ship navigation in ice, ice melting in steam arrangement, low sea is not easy to make ice jam grille.
