Pneumatic performance type test of fan:

Utilize advanced experimental and testing instruments from predecessors to perform performance sampling tests on factory fans in batches. All hypothetical new products and derivative products of standard products developed by the company shall be dismantled according to the GB1236 ventilation fan atmosphere power performance implementation method for the company's duct and chamber types. Only those who have undergone testing in the pneumatic performance implementation room and have obtained a testing statement, and whose performance policy meets the hypothetical requirements, can be put into formal production.
Inspection of finished products before storage:
Only then can it be released for storage; Each wind turbine must undergo the following tests before being put into storage.
The paint is intact and undamaged; Overview detection: The overview is neat.
Operation time greater than 30 minutes, operation inspection: under normal load, no abnormalities;
Use a vibration meter to measure the overall vibration rate of the machine. During operation, do not exceed domestic or enterprise standards;
The noise level is lower than the domestic and enterprise requirements; Noise detection: Conduct noise testing on wind turbines according to domestic standards.
Under the condition of exceeding the planned speed by 20%, the overspeed experiment is carried out by using an overspeed machine to perform the overspeed experiment on the willow. Operating time greater than 10 minutes;
Perform detection on the current passing through the motor during operation, and detect the overall operating current of the machine under normal load. If the current exceeds the standard, the motor settings and equipment layout need to be changed. 
Wind turbine construction technology
Compared with traditional processes (welding angle steel rings and cylinders), it has obvious advantages such as elegant appearance, stable structure, and good flow conductivity. Fan outer cylinder: steel plate cutting (shearing machine or plasma cutting machine) drum forming (three core drum machine) automatic welding (CNC welding machine) spinning forming (automatic spinning machine) flange and cylinder integral forming.
It is welded by a CNC welding machine and assembled on an assembly line. The molding of fan impellers, blades, hubs, and other components is all done using compression molding technology. Accurate size and elegant appearance. The hard supported dynamic balancing machine produced by the Sino German joint stock Shanghai factory is used for calibration. The entire calibration process is computer-controlled, and the impeller balance accuracy is high (able to reach ISO2.5 level), ensuring stable operation.
It has the characteristics of light weight, high strength, flame retardancy, and corrosion resistance. Fiberglass fan: All components such as impeller, air duct, and air cap are made of imported rubber coated resin film, high-quality resin, and fiber cloth, which are scientifically proportioned and molded.
Quality of wind turbine construction
Inspection of materials before entering the factory:
All materials undergo strict inspection before being stored, with a series of complete material storage inspection scales.
Key component inspection:
Should meet domestic and corporate requirements; Before storing the motor, noise, vibration, and current tests must be conducted.
To ensure that the static balance of the impeller meets the requirements of domestic and enterprise standards, the impeller undergoes static balance testing and adjustment before assembly. Perform balance testing and adjustment on the impeller on the dynamic balancing machine to ensure that the dynamic balance of the impeller meets domestic and enterprise requirements. Impellers that cannot be adjusted must be scrapped.
