With the development of the ship, the development of marine equipment is increasing, and the use scene of the marine fan is getting wider and more wide. Basic principle, the marine fan and landless fan do not have a big difference. However, since it is used on the ship, it has its own characteristics in performance parameters, design, structures, and materials.
For example, for reduced size, the centrifugal fan is used to use forward blade impeller; for anti-corrosion, explosion-proof and reduce weight, more aluminum impeller; to facilitate disassembly, axial flow wind mechanism can reduce motor and impeller from the casing The open-open housing structure, centrifugal formation, can be removed from the casing on both sides of the casing or the like. Other special wind turbines such as hovercraft wind turbines are different from land-based products, need special design.
1. When the marine fan is set, it should be avoided, the corrosive gases, large humidity, sun direct and wind-blown rain, and the ground around the fan should be tidy. The fan supporting motor is high in the surrounding environment, and it is often necessary to reduce its performance for the above reasons.
2. When the marine fan is set indoors, the structure of the house should be relatively spacious, and there is a wide enough door, which is convenient for the movement and transport of the fan.
3. There is a sufficient space around the marine fan to operate freely when the fan is running, and can meet the needs of daily maintenance.
4. The installation site of the marine fan should be considered to stay with accessories such as casings, rotors, air boxes, adjustment doors and other accessories, uniform, disassemble, maintenance, etc. The fan is driven by a belt transmission, and it is also necessary to consider the motor to find and replace the vessel.
5. When determining the layout of the marine fan, not only consider the installation space of the fan itself, but also reserve the access and export pipeline, valve, the original motion, oil supply unit, cooling device, and oil and water connection line. Arrangement space.
6. When setting up a multi-stage fan at the same location, we should fully consider the mutual intervals, layout, etc. of the fan, and avoid the mutual impact of the fan operation.
7. For large, heavier fans should be equipped with hoisting hoisting; small and medium-sized fans are often replaced by their use, such as impeller need often replacement, etc., also need to be equipped with a general lifting device.
1. Ventilation ventilation in various cabins;
