Detailed explanation of HTFC centrifugal fire smoke exhaust fan

Detailed explanation of HTFC centrifugal fire smoke exhaust fan:

HTFC centrifugal fire smoke exhaust fan has passed the national fire smoke exhaust CCC and explosion-proof certification, and is widely used in fire smoke exhaust, pipeline supply and exhaust ventilation, and special industrial gas occasions including anti-corrosion and explosion-proof.

The combined structure is easy to assemble and disassemble on site, and has the characteristics of compact structure, small space occupation, wide range of performance parameters, and multiple uses. It is widely used in electric power, chemical industry, textile, paper making, food, metallurgy, gas (oil, natural gas) and other industries.

HTFC centrifugal fire smoke exhaust fan is an efficient energy-saving ventilation equipment with combined structure composed of motor and impeller. It has the advantages of high efficiency, stable operation, low noise, convenient installation, etc. Its impeller is a multi blade fan made of high-quality materials and advanced technology, which ensures that the fan can obtain large flow under small pressure loss.

The HTFC centrifugal fire smoke exhaust fan has a variety of installation forms and outlet angles. The box is dual-use, which can be floor mounted or hoisted. Each surface can be used as the installation surface of the air inlet and outlet. The motor can be placed on the top, side, rear of the box, which can meet the installation requirements of various occasions. The motor is fully sealed structure, without external oil, water and electricity.

HTFC centrifugal fire smoke exhaust fan is an efficient and energy-saving fan, which adopts advanced frequency conversion speed regulation technology and PLC programmable controller control technology, and can adopt stepless speed regulation and continuous speed change of motor according to working conditions. The fan is made of imported motor, fan blade, impeller and other important parts made of high-quality materials. Multi blade blower dedicated for HTFC air conditioner is mainly used for air supply in air conditioning system (also called fresh air supply). It is formed by meshing two synchronous gears of the belt transmission mechanism with a straight cylindrical gear of the belt transmission mechanism. The two synchronous gears have enough tooth surface spacing to ensure the stable speed.

The fan motor of this series is externally mounted, which can operate continuously for more than 30 minutes when the flue gas temperature is higher than 280 ℃, with stable operation and excellent high temperature resistance. At the same time, the advanced aerodynamic control system is adopted, with high control accuracy.

Maintenance of HTFC centrifugal fire smoke exhaust fan:

1. Before installation, carefully check whether the fan blade and casing are damaged or deformed due to transportation, and check whether the bolts are fastened, or they can be used after repair. In case of blade deformation, casing deformation or serious damage, the fan blade and casing shall be replaced immediately.

2. If the motor current is too large, check the motor and coupling immediately.

3. The fan is unstable during operation. Check whether the coupling and adjusting bolt are loose or stuck.

4. When the centrifugal fan operates abnormally, check whether the impeller and air duct have cracks or mechanical damage, and whether the bearing temperature is too high.

5. Whether the driving device and coupling of the centrifugal fan are damaged. If they are damaged, they should be repaired or replaced in time.

6. If the centrifugal fan impeller is not used for a long time, remove the front and rear covers of the impeller (but be careful not to damage the housing), dry them with compressed air, and then install them into the engine body.

7. If the centrifugal fan has abnormal sound during operation, it shall be repaired in time.

8. Regularly check the temperature of the bearing (pay attention to the oil level of the bearing) and the current change of the motor.

9. Replace the bearing once a year.
