Maintenance: 1, the fan blower found abnormal noise during operation, the motor severe fever, live shell, switch trip, you can not start and so on, should immediately stop checking. In order to ensure the safety of explosion-proof axial fan model specification does not allow the fan running repairs, maintenance should be carried out after the commissioning of five minutes or so, confirming that no anomalies start running again. 2, according to occasional supplement or replace the bearing grease (motor enclosed bearing service life without replacing the grease), to ensure that the fan is running in good lubrication, refueling times less than 1000 hours under ambient conditions / closure of the bearings and motor bearings, fuel zl-3 with lithium grease filling 1/3 of the bearing inner and outer rings; non-starvation running. Axial fans, very versatile, and the shaft is in the same direction of the air flow exhaust fan axial fan models, such as electric fans axial fans, air conditioning unit axial flow fan is run fan. It is called "axial flow" because the gas flows parallel to the fan shaft. Axial flow fans are often used in less demanding higher and the pressure of the occasion. Axial Fans fixed position and air movement. Axial fan is mainly composed by the fan impeller and casing, simple structure but the data is very high.
