? A, SJG SJG inclined flow fan Overview oblique flow fan is a new energy-efficient low noise oblique flow fan, oblique flow fan centrifugal fan flow is greater than the total pressure is higher than axial fans, centrifugal smaller than fan. SJG series of oblique flow fan is a fan SWF series derived products, the use of drum-type duct, adjust the air flow direction so as to recover the static pressure, increase air pressure and efficiency. Two, SJG inclined flow fan maintenance environment should be kept clean, fans keep the surface clean, the outlet should not have debris regularly to remove dust and other debris fan and pipe. Fans are only allowed to operate under completely normal circumstances, my colleagues to ensure that sufficient capacity of power supply facilities, voltage stability, non-phase operation, the power supply line must be a dedicated line, the line should not be long-term temporary supply. Fan Fan found abnormal sound during operation, the motor severe fever, live shell, switch trip, you can not start and so on, should immediately stop checking. To ensure safety, do not allow the fan running repairs, maintenance should be carried out after the commissioning of five minutes or so, confirmed that no anomalies start running again. According to the following environmental conditions from time to time to supplement or replace bearing grease (motor enclosed bearing in without replacing the grease service life), in order to ensure the fan during operation good lubrication, refueling times less than 1000 hours / times closed bearings and motor bearings, refuel with zl-3 lithium grease fill the bearing inner and outer rings of 2/3 running short of oil is strictly prohibited. Fans should be stored in a dry environment, avoiding motor damp. Fans at open storage, due defenses. During storage and transport process should prevent the fan bump, so as not to damage the fan three ,, SJG SJG inclined flow fan oblique flow fan characteristics were studied through simulation machine, using a new leaf type and leaf has been a greater flow and pressure, improving the efficiency of the fan. Therefore, both high pressure centrifugal fan axial fan flow coefficient and high coefficient characteristics, with low noise, low power consumption, compact structure and so on.
