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 hood body to be in good condition without power specifications, high pressure parts no leakage. 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 into the wind tunnel, the return air from the roadway is not less than 10 meters, the whole pressure wind tunnel where the supply is greater than the local fan intake air volume and the installation location to return wind tunnel outlet of not 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; partial rear ventilation After troubleshooting, to return to normal work to resume work. 11, at least once every ten days methane wind blocking test, every day should be a work of the local fan automatically switches to the standby local fan test without power hood, during the test shall not affect the local ventilation, test records to be archived for future reference. Liaocheng Flextronics Ventilation Equipment Co. specializes in non-powered and non-powered natural ventilation fan and so on. Axial Fan Installation program, methods and technical measures (1) preparation of construction drawings are familiar with the construction process the arrival of the diffusion tube fan, muffler arrival foundation construction control cabinet position to confirm the detection power supply terminal to confirm the detection handling (2) operating points 1) fan Handling Due to the large equipment, steel size and weight, the application of 8 tons limousine transportation, with 12 tons truck crane for loading and unloading vehicles. In the tunnel according to the actual situation of the tunnel, can pour chain hoist, roll bar and other tools to handle. 2) axial fan installed base of civil engineering for the construction sequence is as follows:? Positioning, actinomycetes, digging, playing mat, formwork tie bars, pouring concrete, sweeping movements face, form removal, backfilling, put the elevation line, centerline. ? Valve installation: Use wind down the chain and were unlucky room inside the electric driving, lifting. ? Diffusion tube, duct installation: the use of electric driving or lifting chain guide diffusion tube, duct, on-site production stent struts, * 25 bolted M10, junction surface with 4mm thick rubber seal. ? Soft connection, spoiler, protective nets installation: soft connection is through the flange bolts (M10 * 25) The diffusion tube is connected with the fans. Fence at the fan inlet connection and adjust the door. ? Axial fan installation: Acceptance basic research horns → → → early leveling equipment in place to find a positive → → secondary grouting grouting, horn size of the installation location to meet regulatory requirements. ? Muffler silencer mount connector piece between: between muffler chip modules in order to ensure easy installation without power roof hood wholesale in the ground, on the leading edge of the floor with the muffler piece connecting hole drilling up and down through the connection piece stacked silencers After natural without power hood manufacturers, with a hoop and then bolting fixed. The connection between the housing: For large wind turbine connected by flange piece muffler, which through the combination of modular housing with bolts M10 * 25 integrally connected, at an intermediate junction additional 4mm thick rubber seal. Hood without power prices, Tianjin no power hood, Flextronics Flextronics ventilators from Liaocheng ventilation equipment Limited. Liaocheng Flextronics Ventilation Equipment Co.
