600mmMining positive and negative pressure flame-retardant air duct, coated cloth positive pressure air duct
600mmMining positive and negative pressure flame-retardant air ducts, coated cloth positive pressure air ducts, Shanxi coal mine positive and negative pressure flame-retardant air ducts
The quality of 600mm mining positive and negative pressure air ducts depends entirely on the materials used. Affordable positive and negative pressure air ducts are made of fiberglass cloth, while high-quality ones are made of coated cloth material, which is also used for explosion-proof water bags in coal mines. This material is sturdy and wear-resistant, mainly due to its high strength. This type of coated cloth positive negative pressure air duct is generally used in coal mines, iron mines, tunnel factories, and other places. According to different materials, positive and negative pressure air ducts are also divided into flame retardant and anti-static, non flame retardant and anti-static, flame retardant ones are expensive, and non flame retardant ones are moderately priced. The 600mm mining positive and negative pressure air duct has the advantages of no air leakage per kilometer, beautiful appearance, wear resistance, corrosion resistance, and high adhesion strength between the inner ring pressure strip of the air duct spring and the coated cloth; 600mm mining positive and negative pressure air duct is used for positive and negative pressure ventilation of local fans in coal mines, tunnels, bunkers, and underground areas.
Positive and negative pressure flame retardant air duct for mining. Standard parameters for positive pressure air duct:
Internal pressure resistance: ≥ 5000pa
Expansion rate: ≤ 3%
100 meter air leakage rate: ≤ 4%
Other * capabilities: flame retardant, anti-static, heat-resistant, cold resistant, etc., all meet the standards of the coal industry.
Specification of positive and negative pressure flame-retardant air ducts for mining: Ф 300mm 、Ф 400mm 、Ф 450mm 、Ф 500mm 、Ф 600mm 、Ф 800mm 、Ф 1000mm
The length of the positive and negative pressure flame-retardant air duct for mining can be customized according to customer needs, including 5 meters, 10 meters, and 20 meters.
Precautions for using positive and negative pressure flame-retardant air ducts for mining:
The appropriate specifications of air ducts, elbows, and other components should be selected according to the specific conditions of the underground tunnel and the requirements of the fan air volume.
The suspension of the air duct should strive for straightness and ensure that each suspension buckle is evenly stressed to avoid the weight of the air duct being concentrated on some suspension buckles.
Positive pressure air ducts and negative pressure air ducts used in coal mines, flame retardant and anti-static air ducts with wind pressure resistance *: After wind pressure resistance testing, the air ducts must not produce phenomena such as detachment, tearing of coating cloth, and opening of joints. The expansion rate of the diameter of the air duct shall not exceed 3.0%.
Generally, when the ventilation length is within 200m, it is advisable to use a mining air duct with a diameter of 400mm; When the ventilation length is between 200-500m, it is advisable to use a mining air duct with a diameter of 500mm; When the ventilation length is between 500 and 1000m, it is advisable to use a mining air duct with a diameter of 600mm; When the ventilation length is over 1000m, it is advisable to use a mining air duct with a diameter of 600mm or more.
Tai'an Yucheng Mining Equipment Co., Ltd. mainly produces flame-retardant air ducts in black, orange yellow, and dark green colors.
