CB T295 Marine Mushroom Ventilation
CB T295 Marine Mushroom Ventilation has a ring of water retaining grooves around the periphery; one side of the water retaining groove is open, and at the bottom of the opening a short pipe is connected; the short pipe is connected to the drain pipe, which is bent to the side of the wind turbine; at the bottom of the drain pipe there is a water retaining plate. The diameter range is DN150-1400.
Overview
Marine Mushroom Ventilation flushing experiment：
With a diameter of not less than 12.5 nozzle, water pressure of not less than 0.25Mpa, and then not more than 1.5mm from the ventilation cylinder for flushing, flushing time 3min, the results should be consistent with the "parts of the water beads, sealing packing and wind tube contact indentation width of not less than 0.5t (t for the thickness of the wind tube tube 〉.
Marine Mushroom Ventilation indentation experiment：
In the wind and rain sealing packing, evenly coated with white powder, close the wind and rain cover, and then open, check the sealing packing and wind tube edge contact indentation width, the results should be consistent with the requirements of 4.7.
