JK67 mine fans

To ensure the treatment effect and boiler equipment uptime, during design and construction, should be based on the specific requirements, consider the noise sound intensity, audio and other factors, noise, sound absorption and JK67 mine fan ventilation detailed design, good detail treatment . The thickness of the insulation chamber size, the type of sound-absorbing material, the thickness calculated. Muffler inlet muffler generally used 25dB (A) or so. Minimize noise radiation area, removing unnecessary metal plate surface. Vibration control panel surface between the sound source and the acoustic cover and the underlying connection with soft materials. Connecting pipes and thin-walled steel chimney JK67 mine fan noise control is the weak link in the wall outside the dressing 5cm thick glass fiber cotton, dried steel truss, then 2cm thick steel mesh cement stucco. The glass fiber cotton is fixed to the plate, absorb reverberation noise insulation chamber. Mine fan JK67-2-NO.4.5 Henan mine fan, local fan machine equipped with motors are IP54 \ IP55, explosion-proof requirements are explosion-proof electrical equipment inspection certificate, explosion-proof electrical performance in line with national standards GB3836.2 . In an explosive environment, practical metal material pairings local fan impeller and casing were confirmed by friction sparks safety inspections and obtain inspection certificate, for use in explosive atmospheres fan collector, housing, compartment manifold, impeller and other components antistatic and flame retardant according to the provisions of MT113. Mine fan JK67-2-NO.4.5 mine in Henan Bureau Ventilator fans supporting the motor stator resistance and then cold insulation resistance at a rated voltage of 380V is greater than 0.38 megohms, rated voltage of 660V is greater than 0.66 megohms When 1140V greater than 1.14 megohms. 95% of rated speed fan motor is running under its maximum output power does not exceed the rated power of the motor. Mine fan JK67-2-NO.4.5 mine in Henan Fan specification is complete, adaptable, air distance. Bureau of fan air volume and value of the total pressure of a variety of different combinations of air distance from 80 meters to 600 meters range (series using air distance of up to 1200 meters), can be equipped with hairdryer cloth in accordance with user needs meet the conditions required. High operating efficiency. Single-stage and two-stage work round the highest total pressure efficiency of 92% and 83%, respectively, of the rotary type highest total pressure efficiency of 85%, with significant energy-saving energy-saving effect. Smaller, lighter, mobile flexibility.
