Technical Standards for Forward-Curved Double-Inlet Centrifugal Fans

Technical Standards for Forward-Curved Double-Inlet Centrifugal Fans How much do you know about the technical standards for forward-curved double-inlet centrifugal fans? These fundamental details directly impact future usage. As users, we must gain as much understanding as possible about forward-curved double-inlet centrifugal fan equipment to ensure optimal operation. The primary technical benchmarks for forward-curved double-inlet centrifugal fans are as follows. Operational Standards for Forward-Curved Double-Inlet Centrifugal Fan Units: First, prior to startup, personnel must meticulously inspect all connections within the unit. Ensure all joints are secure and bolts are tightened; any loose bolts must be fastened immediately. Pay close attention to lubrication quality, appropriate lubricant quantity, and whether the fan operates smoothly without irregularities. Before vehicle startup, the suction valve must be closed, followed by activating the forward-curved double-inlet centrifugal fan. Once the unit gradually reaches the specified speed, the suction valve may be opened. During operation, the forward-curved double-inlet centrifugal fan unit must be immediately shut down if any abnormal conditions occur, such as severe vibration, sudden unusual noises, or abnormal temperature rise in bearings or the motor. Maintenance Standards for Forward-Curved Double-Inlet Centrifugal Fan Units: During routine operation, personnel must regularly inspect connecting components, primarily verifying whether bolts, pins, and other fasteners are loose. Tighten any loose fasteners. Typically, lubricating oil requires replacement every 3 to 6 months of fan operation. Maintenance Standards for Forward-Curved Double-Inlet Centrifugal Fan Equipment: To ensure normal operation, maintenance cycles should be conducted annually and every three years.
