Aluminum non-powered ventilation of repair and maintenance: 1, aluminum without power ventilation under normal circumstances, about a month of continuous operation shall be to inject sodium calcium bearing grease or molybdenum disulfide grease with butter site. Fan runs continuously for 3-6 months to replace a roof ventilators grease to the bearing space is filled 2/3 appropriate. 2, aluminum without power ventilators regular maintenance, eliminate internal fan fouling, dirt. 3, no power ventilation in aluminum boot, shutdown or operation, as found to be normal cyclone-type roof ventilators, including temperature, vibration and noise streamlined roof ventilators, should repair immediately. 4, use the triangle belt adjustment device keep uniform tension state, can not be too loose or too tight spiral roof ventilators, several triangle tape should be the same length. Ventilation is to prevent accidents resulting in greater damage to persons or property in a large number of harmful gases when the production equipment workshop fortuitous accident or malfunction occurs, may suddenly diffuse or explosive gases and set the exhaust system. Roof ventilation applications necessary measures to ensure that key safety and security of workers in the life of production safety accident Ventilation.
