What is the 3C Fan Box Inspection Standard

 3C Fan Box Inspection Standard: 3C Fan Box to the appearance of smooth, to have unprocessed defects and scratches, coating to uniform. In the 3c fan box shell welding, welding should be full of debris, bubbles, virtual welding defects, structural stability. 3c fan box impeller rotation normal, smooth operation, no abnormal vibration and sound, no loose fastening connection. When the 3C fan-box is running, the phenomenon of serious heat (= 90 ° C) and shell electrification should not occur. Should the insulation resistance between the 3C case and the motor windings be greater than 0.5 m? 3C fan box can use centrifugal fan or axial fan, so it must be in 280C continuous operation for more than 30 minutes. The visible part of the fan housing shall have the fan rotation direction mark and nameplate, and the main parameters shall be in accordance with the actual. 3C fan box inspection standards to meet the requirements of national standards, the above rules belong to the general requirements of the industry, users in the selection of 3C fan box should pay attention to the above details. When choosing 3C fan box, the starting valve should be set to prevent the load of the motor during cold operation. Dust protection measures should be taken during installation. In the centrifugal impeller and rolling bearing damage, immediately repair or replacement to prevent module vibration: for spindle bearings, whether new or old shaft, must be tested when applied. In the installation and maintenance of 3C fan box, according to the box fan and motor two-axis technical standards, the flatness and coaxiality of the operation in 0.05-0.0. MM Center, 2 couplings should be left 5-6 mm gap. Thus, the bending protection of the working shaft is improved.
