Industrial axial exhaust fans use a motor to drive the impeller and create axial airflow, commonly used for wall-mounted exhaust and ventilation in workshops. The product structure includes the barrel, motor bracket, impeller, protective guard and junction box. Taizhou Yufeng Intelligent Equipment Co., Ltd. plans an axial exhaust fan production line for ventilation equipment manufacturers, achieving standardized production from sheet metal parts to complete machines.
Barrel and structural part production
The barrel is formed by stamping or rolled plate welding to ensure dimensional accuracy and roundness. The barrel production station is equipped with stamping, bending and welding equipment, and surface treatment is performed after forming. The motor bracket is welded with the barrel, and bracket position accuracy affects the gap between the impeller and barrel. Structural parts are produced to drawing standards to reduce dimensional variation.
Impeller assembly and dynamic balancing
The impeller is the core part of an axial fan. After blades and hub assembly, dynamic balancing equipment checks the balance, and counterweights adjust it to the balance grade. Impeller balance directly affects vibration and noise, making it a quality control focus. Balance data is recorded and bound to the product number, and the gap is rechecked after impeller and motor assembly.
Guard and accessory assembly
The protective guard is designed according to safety standards, with mesh spacing and strength meeting regulations. The guard assembly uses dedicated fixtures for positioning and reliable fixing. The junction box, switch and power cord are installed according to electrical requirements. After assembly, electrical inspection and grounding tests are performed.
Factory test items
Before shipment, axial exhaust fans undergo insulation, grounding, leakage current, speed, current and noise tests. Test equipment sets parameters according to product standards and judges and records automatically. Qualified products enter the packing stage, and the test report is part of the delivery documentation.
Cycle and capacity
Axial fans have many specifications. The line uses flexible stations to adapt to different barrel diameters. The assembly cycle adjusts according to product specifications, and in a typical configuration one unit is completed every 5 to 8 minutes. The line reserves extension positions for automatic assembly equipment.
