Liaocheng Flextronics Ventilation Equipment Co. specializes in non-powered and non-powered natural ventilation fan and so on. Axial fan is driven by the motor running, in fact, are the same for any equipment, you want to work together, there must be a similar "engine." In the choice of axial fan motors steel roof fan manufacturers, hoping to be able to drive the impeller motor up to speed quickly and work properly. Motor starting, including start and accelerate the whole process of electricity. Starting its way into full voltage starting and decompression starter. Reasonable choice of motor starting method, must be based on the capacity of the supply network, the mechanical load on the starting torque requirements, the characteristics of the motor itself and other factors, specific analysis, in order to obtain the specified start time. For example, a large capacity of the grid, the motor starting current does not cause a significant voltage drop in the power line, in addition to natural roof fan manufacturers, grid lines and equipment allow short-time control through a sufficiently large starting current, can use the total pressure start; if the fan in the starting torque is not required, and not in terms of grid capacity is relatively large electric motor, the main consideration how to reduce the starting current and the use of vacuum starter. Liaocheng Flextronics Ventilation Equipment Co. specializes in non-powered and non-powered natural ventilation fan and so on. Fans of the body to be in good condition, no leakage of high pressure axial fan site: local fan body to be in good condition, no leakage high pressure parts. Must elevate local fan when installed over 0.3 m (with track surface counting) and securely installed. At the same time must be made by the designated officer responsible for the management, to ensure the normal operation. 7. Local Fan and pressed into starting device must be installed in the plant into the wind tunnel roof fan manufacturers, return air from the roadway is not less than 10 meters, the wind tunnel where the whole supply pressure is greater than the local fan intake air volume and installation site to return air wind tunnel can not be less than 0.25m / s. 8, should use anti-static, flame retardant duct. Duct hanging straight no dead corner, every ring will hang, found lacerations promptly repaired or replaced. Duct bend elbows to be set up, you can not turn tight corners, standard specifications and install local fan and spare local fan automatically switches to work cross-duct joints shall be specified in the operating procedures. 9, normal operation and standby local fan were stopped after power failure, when power is restored, the local fans and spare local fan to work on their own are not allowed to start, you must manually open the local fan. 10, using the local fan sites for wind wind power lockout must be implemented to ensure the normal operation of the local fan when stopped or after stopping the wind can stop the wind zone off all non-intrinsically safe electrical devices. When working local fan failure, local fan switch to the backup job, you should stop within the scope of work of the local fan ventilation, troubleshooting; local ventilation when troubleshooting rear roof fan manufacturers, to return to normal work to resume work. 11, once every ten days methane wind blocking test at least once a day should work with local fan spare local fan automatically switch test, shall not affect the local ventilation during the test, the test records to be archived for future reference. dwf roof fan manufacturers, Beijing roof fan manufacturers, Flextronics Flextronics ventilators from Liaocheng ventilation equipment Limited.
