Processing technology used: cutting, welding, bending, etc.
The marine ventilation cover is a marine exhaust fan structure, which is a weather tight and airtight steel door, including a door panel and a door frame, which are hinged with the door frame. It is characterized in that the sealing strips and air tyres are embedded in the sealing grooves of the door panel and the door frame, and the inner cavity of the air tube is connected with the pneumatic device.
Process: cutting, welding, bending, etc.
1. The spiral blade produced by the continuous cold rolling method overcomes the shortcomings of the traditional spiral blade production process, such as poor precision, difficult forming and high consumption of materials, and low production efficiency.
2. After the blade is formed, the surface is smooth and the dimensional accuracy and surface hardness are high.
3. Provide continuous integral blades according to the helical length required by customers, with good rigidity, convenient and fast welding and assembly during use.
