Definition and definitions of sea bottom filter, sea water filter / sea bottom filter:
The sea door is the sea channel used for extracting sea water in the ship, and it is controlled by one or two big valves. They are usually divided into high submarine gates and low submarine gates. Both sides need to be equipped with seawater filters:
High sea bottom doors, sea water filters, and low floor sea water filters (and sometimes an emergency submarine door, sea water filters)
This high sea water filters and low sea water filters and emergency sea sea water filter is based on the CB/T497-94 standard ship shipbuilding industry by inhalation of coarse water filter water filter /, and combined with the modern ship requirements, improve the design and the formation of the company's FH series of products.
Standard for implementation of high sea floor doors, sea water filters and low floor doors, seawater filters, and emergency sea water filters for subsea gates:
The marine sea water filter CBM1061-82 (imitation standard: JIS F7121 Japanese standard cylindrical filter)
The form of sea water filter includes: A type through sea water filter, B type right angle sea water filter
English Name: sea water filter
Definition: filter for filtering impurities in sea water.
The ship with inhalation of coarse water filter CB/T497-94
Type: A (through sea water filter), AS type (through sea water filter), B type (right angle sea water filter), BS type (right angle sea water filter), BR type (right angle sea water filter), BRS type (left right angle sea water filter)
Nominal pressure; PN0.1MPA
Nominal diameter DN40-DN500 (non-standard custom: DN500-DN1000)
Applicable medium: sea water, fresh water
Material: Body: carbon steel, valve cover: carbon steel, thread, stainless steel, 304#
The filter screen of the sea water filter can be manufactured with stainless steel 304 or stainless steel 316 or stainless steel 316L according to customer requirements.
The ship on the standard sea water filter JIS F7121 filter with cylindrical vessel
Valve body; ductile iron / cast steel; filter screen; stainless steel 304#
Nominal diameter; DN25-DN500
Type: A type through sea water filter, B type right angle sea water filter
Nominal pressure; PN, 5K, 10K

Importance of maintenance of sea water filter / sea bottom filter for submarine door:
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.
