Fire-retardant, wear-resistant and anti-twisting of 50 cm mine positive pressure and negative pressure air duct
Mine positive pressure duct negative pressure duct axial flow fan duct dust removal fan duct tunnel ventilation belt mine duct manufacturer
Negative pressure air duct is used for negative pressure ventilation of local fans in coal mines, tunnels and underground mines.
Test Report on Ventilation Performance of Axial Fan Wind Tube Diameter, mm
Negative Pressure Resistance of 100-meter Wind Resistance (N.S 2/M 8): When the wind tube is tested under negative pressure, its value should conform to the following table:
Diameter of air duct (mm) steel wire spacing (mm) negative pressure strength (pa) 600 150 (> 3140 600 100 (> 4900)
The shrinkage rate of the diameter of the air cylinder of the dust removal fan is more than 1%.
The mine ventilation belt of the tunnel has the characteristics of antistatic and resistance. Standard No. MT165-2007 for production of negative pressure air duct; positive pressure air duct, using high temperature and high pressure cylinder integral one-time forming technology, longitudinal seamless, with flame retardant, antistatic, low wind resistance, no air leakage, high strength advantages, suitable for underground coal mine. In the roadway should be suspended, so as to make it straight, tighten the hanging, hang around, make up for bad, turn slowly, remove water, in order to reduce the resistance of mine ventilator manufacturers.
The idea of infrared heating bonding is put forward, and the technology of infrared heating bonding is briefly described. An infrared heating device for bonding flame retardant, anticorrosive and rubber-plastic duct cloth for mining is introduced. Testing report on ventilation performance of air duct: diameter of air duct, 100-meter air resistance (N.S 2/M 8), 100-meter air leakage rate,% 300 < 1728.0 < 5.0 400 < 410.0 < 5.0 500 < 134.0 < 5.0 600 < 54.0 < 5.0 800 < 13.0 < 5.0. Uses: Used in coal mine, tunnel, subway engineering, ship, underground local extraction-oriented ventilation mine air duct manufacturer. 50cm mine positive and negative pressure air duct flame retardant, wear-resistant and toss-resistant welcome old and new customers friends to come to negotiate patronage! Wish you a good mood every day!
