Fan performance parameters
The performance parameters of the fan mainly include flow, pressure, power, efficiency and speed. In addition, the size of noise and vibration is also the main technical index of the fan. Flow is also called air volume, which is expressed by the volume of gas flowing through the ventilator per unit time. Pressure is also called wind pressure, which refers to the increase in pressure of the gas in the ventilator, which is divided into static pressure, dynamic pressure and total pressure. The power is Refers to the input power of the fan, that is, the shaft power. The ratio of effective fan power to shaft power is called efficiency. The total pressure efficiency of the fan can reach 90%.
Future development trend of fans
The future development of the fan will further improve the aerodynamic efficiency, device efficiency and use efficiency of the fan to reduce power consumption; replace the large centrifugal fan with a shaft-flow fan with adjustable blades; reduce fan noise; improve smoke exhaust, Abrasion resistance of dust exhaust fan impeller and casing; realize variable speed adjustment and automatic adjustment.
As an ideal fire-fighting facility, fire-fume exhaust fans have been widely used in high-rise buildings, underground buildings, tunnels, and drying rooms, such as ventilation and high-temperature exhaust. Then maintenance is also very important during use. The price of Tianjin ventilator will mainly tell you about the maintenance method today:
1. Disconnect the main power supply, hang the "No Closing" sign, the price of the ventilator, and check whether the motor ground wire is good.
2. Tighten all screws and couplings.
3. Check whether the insulation resistance of the motor meets the requirements and check the main circuit contacts. If the contact is severely ablated (the contact point is worn down to 1/3 of the original thickness), the ventilator manufacturer should replace the contact.
4. Adjust the tightness of the belt, the ventilator, and move the wind wheel by hand to observe whether the rotation is stable.
5. Check and replace the gaskets and sealing packings between the joint surfaces.
6. Clean the inside of the motor and wind wheel, filter and case. The paint should be brushed off.
7. Add lubricating oil to the rotating parts to ensure the flexibility and stability of the coupling and bearing.
8. Check whether the mechanical opening and closing action of the regulating valve is reliable and flexible, and the opening and closing angle signs are clear.
9. Manually check whether the indicator light, voltage and ammeter are working normally, whether there is abnormal sound during the operation of each component of the fire exhaust fan, and whether the three-phase current value is balanced.
10. Check whether the components in the control box of each remote point are normal.
11. Start and stop for three consecutive times, and check whether the remote control is correct and reliable at each point.
12. Test run the fire-fume exhaust fan for two hours and observe whether the motor bearing temperature and motor temperature rise are normal. Ensure that the fire exhaust fan is operating normally.
