The closed fan is the main equipment for dust removal, air supply and other equipment feeding. The closed fan is the main equipment for dust removal, air supply and other equipment feeding. A rigid impeller feeder, usually a closed fan structure, consists of a rotor impeller with multiple blades, a casing, a seal, a reducer and an electric motor. The discharge device of the enclosed fan manufacturer is the main equipment for dust removal, air supply and other equipment feeding. The characteristics of the closed fan: Compact structure, beautiful appearance, easy to use, stable operation, low noise, due to the formation of the shaft, the gearbox blades are separated from the shell at a certain distance, which can greatly improve the high temperature and lubricity.
The closed fan can also be designed, manufactured, installed and debugged according to user requirements. Usually installed in the main oil circuit or shock absorber back pressure oil circuit. When the transmission automatically upshifts and downshifts or when the lock-up clutch starts to lock and unlock, the oil pressure will decrease to reduce gear shifting, locking and Unlocking the vibration makes the vehicle more balanced. Its function is to control the size of the oil pressure in the oil circuit. Low cost, easy installation, corrosion resistance, wear resistance, durability, stable performance, high dust removal rate, dust removal efficiency generally can reach 95-97%, the dust removal efficiency of the double-tube dust collector can reach more than 97%, strong adaptability, and usable Dust removal and desulfurization in various industrial boilers and dusty places, stable operation and simple maintenance.
The closed fan has strong corrosion resistance: the closed fan manufacturer adopts the planetary rotation principle, the input and output shafts are on the same axis, and have the uniqueness of being directly connected to the motor, so the structure is compact, the appearance is beautiful and novel, and the volume is small. Lightweight. Reliable and stable operation, low noise, low failure, and long life. The tooth part adopts bearing steel. Good performance and high wear resistance. Bearings and gearboxes should be kept away from the valve body to avoid the influence of high temperature and dust. The front cover and back cover have good sealing performance, which can prevent dust leakage and extend the service life of parts and lubrication system. The machine has strong overload capacity, low impact resistance and low moment of inertia, which is suitable for frequent starting and reverse rotation. If users need special specifications, hydraulic pressure, sprocket drive and other unloaders, they can contact our factory, all products can be manufactured.
The characteristics of the closed fan: the impeller is elastic, the sealing is good, the impeller is stuck, the bearing is outside the valve body, and the material particles do not directly contact the reducer, thus prolonging the service life of the unloader. Easy to maintain. The stainless steel shell of the closed fan is corrosion resistant, has high hardness, is not easy to stick, and is easy to transport medicines, food and similar materials.
