Knowledge of the air fan

What is the AC fan: The AC fan is mainly used for the heat dissipation of electronic products and the small exchange fan of general purpose. It is widely used in the household electrical appliances industry, the machinery industry, the manufacturing equipment industry and other products with the ventilation and heat dissipation requirements. The motor structure of this kind of fan is a hood - level motor, and the rotor is fixed with the impeller. The air duct is integrated with the positioning frame and the stator. This structure is simple, easy to produce, and easy to install and use. Classification and product introduction of AC fan: Classification in appearance: 8025.8038.9225.9238.11025.12025.12038.15050.17238.17251.20060 To use voltage classification: 110V, 220V, 380V E - bearing type S-> Sleeve bearing B-> single ball bearing D-> double ball bearing F - rated voltage 11->AC110V 22->AC220V 38->AC380V G - speed type L-> low speed X-> ultra low speed H-> high speed E-> ultra high speed Speed in M-> The environment conditions of the AC fan: Working temperature -----------10 C ~60 C Storage temperature ------------40 C ~70 C Humidity - 10%~80%RH Storage humidity - 10%~90%RH Product safety performance experiment: 1. Drop test In the case of minimum packaging, the fan can withstand the fall of any side down from 30 centimeters to 10 millimeters of thickness. 2.Lock the protection When the motor is locked at the rated voltage to stop the operation, the fan can withstand 72 hours without fire and combustion. 3.Insulation resistance strength Can resist a 2500V voltage of 2 seconds 1m between the two wire and the body
