Livestock fan maintenance, repair and maintenance electrical circuit 1, the control valve mechanical opening and closing movement is flexible, reliable, and opening and closing angle flag is clearly visible. 2, the light and the voltmeter, ammeter are all normal. Fans of the components operate without abnormal sound, arcs, roof ventilators, three-phase current imbalance. 3. Check the remote control box element points are all normal. 4, continuous start-stop operation, the roof ventilation company, check the point is correct and reliable remote control. 5, commissioning two hours, observing the motor bearing temperature, motor temperature is within the normal range. 6, suitable for warehousing logistics aluminum without power ventilation of repair and maintenance: 1, aluminum without power ventilation under normal circumstances, continuous operation about a month, roof ventilators tender shall be injected into the bearing platform with butter calcium sodium grease or molybdenum disulfide grease. Fan runs continuously for 3-6 months, replace a grease to the bearing space is filled 2/3 appropriate. 2, aluminum without power ventilators regular maintenance, Tianjin roof ventilators, eliminate internal fan fouling, dirt. 3, no power ventilation in aluminum boot, shutdown or operation, as found to be normal, including temperature, vibration, noise, etc., should be inspected immediately. 4, use the triangle belt adjustment device keep uniform tension state, can not be too loose or too tight, a few triangle tape should be the same length.
