MUSHROOM VENTILATORS FOR SHIP

Here, our company professionally introduces a C-type external hoist ventilation shaft with axial fan:

This standard CB/T295-2000 marine fungus-shaped ventilator, CB/T 4444-2017 marine fungus-shaped ventilator is suitable for the design, manufacture and acceptance of ventilator installed on the open deck of marine ships.

Technical Agreement on Marine CB/T295-2000 Marine Fungus Ventilation Tube-CB/T 4444-2017 Marine Fungus Ventilation Cap:

1. Marine ventilator-The surface of marine fungus ventilator should be flat and smooth, without sharp edges, distortion, or skew.
2. The diameter deviation of the wind cylinder and hood of the marine ventilator is ±3mm, and the deviation of the verticality is 2/h1000 (h is the height of the ventilator cylinder)
3. The welding surface of marine fungus-shaped vents should be free of cracks, slag inclusions, burn-through, and unfused defects.
4. The opening of the weather-tight cover of the fungus-shaped ventilator for ships should be flexible, and the movable part should be coated with neutral lubricating grease.
5. The derusting of the internal and external surfaces of the steel parts of the fungus-shaped ventilating cap should reach the Sa2 level or St2 level specified in GB/T8923, and then two antirust primers.

About CB/T295-2000 marine marine fungus ventilator-marine fungus ventilator test method:

1. Flushing experiment of marine fungus ventilator:
Use a nozzle with a diameter of not less than 12.5, the water pressure is not less than 0.25Mpa, and the water is not more than 1.5mm away from the ventilator, and the flushing time is 3min. The result should be consistent with "No water beads in all parts, and the sealing filler is in contact with the fan. The width of the indentation is not less than 0.5t (t is the thickness of the air cylinder body)>.

2. Embossing experiment of external ventilator with axial flow fan-shaped ventilator for marine use:
At the place where the weather-tight seal packing is uniformly coated with white powder, close the weather-tight cover, and then open, check the width of the indentation of the seal packing and the edge of the air cylinder, and the result should meet the requirements of 4.7.

3. Appearance inspection of external ventilator funnel-shaped ventilator with axial flow:
Visual inspection is to be carried out, and the results must meet the standards.

4. Dimensional inspection of funnel-shaped ventilating cap with axial fan for external opening and closing of ship:
Check the deviation of the diameter and verticality of the air cylinder and hood with a measuring tool. The result should meet the requirements of 4.3.
