Nanfeng NFC50-3KW Submerged Integrated Transmission Aeration Fan Equipment

characteristic

1. Reduce energy consumption:

The submerged blower has a higher speed to reduce reverse flow and relatively reduce energy consumption.

2. Tranquility:

The submerged blower, due to being placed in water, refracts the sound into the water at the interface between air and water, without transmitting it into the air. At the same time, the water and the groove wall are also refracted back to achieve the effect of sound extinction, without causing secondary pollution.

3. No need to create a soundproof room:

Due to being placed in water, the submerged blower does not require the production of a separate soundproof cover or factory building. At the same time, the blower is placed in a sink and does not occupy any space, so it can effectively utilize space.

4. Solid and practical construction:

The motor and body are directly connected (without the trouble of traditional adjustment belts). The motor and machine itself are all enclosed with O-ring seals, without any risk of water ingress. If the machine stops due to overheating, please clean the casing to achieve heat dissipation.

5. Extended bearing life:

The application of pre pressing plates to bearings reduces bearing clearance, reduces vibration and noise, and thus prolongs the service life of the bearings. [1]

matters needing attention

Firstly, please check the type, outlet diameter, rated output frequency, phase number, voltage, current, pressure, air volume, etc. of the submerged blower on the nameplate to see if they comply with the specifications you require. During transportation, the product must not be damaged. Especially, it is necessary to pay attention to whether screws and nuts are loose. Regarding accessories, please confirm the type and number of parts for errors. The fan must operate correctly according to the indicated direction. When you use it, A power supply with appropriate capacity is required. If a small capacity power supply is used, it may fail to start. Therefore, please pay attention to the power supply capacity

Please confirm whether the frequency and voltage of the power supply you use match the specifications recorded on the nameplate. The rated voltage of the submerged blower must be within ± 10% of the allowable value. Please do not extend the cable arbitrarily. As extending the cable may cause a voltage drop above the allowable value, please be careful not to pull the cable when moving the submerged blower to avoid cable breakage, Loss of insulation can cause electrical leakage. Please use a grounding wire accurately. To prevent electric shock, it is required to install a leakage circuit breaker to prevent electric shock. To protect the submerged blower and extend its service life, it is recommended to install a fuse free switch. Do not bury the submerged blower in mud or sand piles, and try to place it in a clean and frequently flowing place, Please use the same caliber as the submerged blower for the air outlet piping. If using piping with a smaller caliber than the submerged blower, improper piping may result in increased pressure loss, reduced air volume, and increased current. Do not allow water to penetrate into the submerged blower at the connection part of the water piping

Firstly, turn on the power switch and confirm if there is air intake at the inlet silencer. If it is reversed, immediately stop the operation and change to the correct direction. The pressure and motor current values at the outlet should be within the range of use. If there are any exceeding conditions, check the cause before operating. Pay attention to whether the submerged blower has abnormal vibration and noise. If it is left unused for a long time, it is easy to cause the impeller to get stuck, so please run it for 30 minutes every week, If placed in a damp place, please implement it daily.

Do not let water or foreign objects fall into the installation process of the submerged blower
