Liaocheng Flextronics Ventilation Equipment Co. specializes in non-powered and non-powered natural ventilation fan and so on. Seven needs no power ventilators made: 1, no power roof ventilators and entries should be based on aerodynamics, made a streamlined, the fan inlet / outlet flow smoothly, reducing pressure loss. 2, glass fiber reinforced plastic material formulations, to be performed in accordance with the relevant requirements of the plasticizer, add the appropriate amount of anti-aging and prolong life. 3, roof fan must have a reliable measures to prevent rain, snow penetration without power ventilators. 4, no power ventilation enclosure should be able to withstand the devastating impact of the local outdoor maximum wind speed. 5, should be set at the bottom of the security fence. Security fence is safe, reliable stainless ventilators price, can effectively prevent the decrease, in order to avoid an accident to equipment or parts. 6, roof fan should be provided with an efficient network, all stainless steel stainless steel non-powered ventilation, mesh 30 x 30 mm. 7, no power ventilation should be static and dynamic balance test before delivery, after passing the factory before. In the static, dynamic balance, the fan impeller operation allows RMS vibration velocity is less than or equal to 6.3 mm / s stainless steel ventilation, and shall comply with JB / T 9101 -. 1999 "fan rotor balance" Liaocheng Flextronics Ventilation Equipment Co. specializes After the non-powered and non-powered natural ventilation fans, etc. The use of axial fans how to debug an in axial fan for proper installation, the first part of the function of each debugging, see if you can work properly. 2, First check the fan rotation is smooth when you can try to see if there are stuck blade struck or without rotation. 3, internal checks whether the fan was not removed debris and keep it clean inside and clean the stainless steel roof ventilation unit price, can be cleaned with a rag. 4, the pipeline operator after checking the status of the throttle away from the fan. 5, after the fan starts, it continues to rotate after half an hour, stop working, check the parts are loose phenomenon The above description is a fan of commissioning after installation, I hope you can help. stainless steel ventilation hood, Ya'an stainless steel ventilation, ventilation by Flextronics Flextronics Liaocheng ventilation equipment Limited.
