Introduction to the advantages and corrosion resistance of FRP roof fan

FRP roof fan is a new type of ventilation equipment made of anti-corrosion FRP material, which belongs to axial flow fan. Because the outer frame of the fan is made of anti-corrosion FRP material, the working principle is to use negative pressure to exchange air, achieve the purpose of air circulation, ventilation and cooling, so it is called FRP negative pressure fan. FRP roof fan has the characteristics of corrosion resistance, large air volume, low energy consumption, low speed, low noise and so on.

Advantages of FRP roof fan:

1. Good ventilation effect: FRP roof fan has good ventilation effect, which is very suitable for pipe ventilation or air supply;

2. Corrosion resistance: it can resist acid and alkali corrosion and has a long service life;

3. Low noise: the FRP roof fan is designed with a reasonable impeller angle according to the air flow mechanics. During operation, there is no mechanical friction, and the reasonable blade shape reduces the noise to a low level; the noise generated by the FRP roof fan is high-frequency noise, so long as there are obstacles, it can be sound insulation;

4. Stable operation: the optimized impeller reduces the axial force to a low level, and the impeller with high efficiency. After static and dynamic balance correction, the whole machine runs smoothly. Without any damping device, the bearing amplitude is relatively small.

Corrosion resistance of FRP roof fan:

Corrosion resistance of FRP roof fan: the impeller of the fan can be made of ABS (engineering plastic) FRP (glass fiber reinforced plastic) and aluminum alloy plate according to the different corrosivity of the working air medium. For the FRP roof fan with high pressure requirements and high fan speed, the impeller surface is specially galvanized and sprayed with plastic corrosion resistance treatment, which not only reduces the weight of the whole machine And has good corrosion resistance.

Before the installation of FRP roof fan, it is necessary to carry out the following procedures: equipment inspection - test run. The inspection of the equipment shall first depend on whether the equipment is deformed or damaged during transportation, whether the connecting parts are firm, and whether the shutters are closed (whether the opening mechanism is normal, and whether the safety net is in place). The air volume, noise, vibration and energy consumption of the fan test shall be checked to see if they are qualified. In case of any unknown fault, the fan shall be shut down immediately.

If the FRP roof fan is not used for a long time, it should be sealed in a dry environment to prevent damage to the motor insulation. Apply anti rust grease on the rusty metal parts to prevent rusting. During the shutdown period, check whether the main power switch is indeed in the off position. In case of accidental start-up.
