Features: 1. Because the impeller works in the gas, it does not need lubrication, and the gas discharged is oil-free. It is an ideal pneumatic conveying source for chemical industry and food industry. 2. The ventilator is a volume operated blower. When used, the flow rate fluctuates very little with the change of pressure. But the flow rate varies with the speed. Therefore, the choice of pressure service is very wide, flow selection can be selected by speed to meet the demand. 3, the fan speed is higher, the interval between the rotor and the rotor, the rotor and the gas is smaller, so the leakage is less, the volume efficiency is higher. Our factory has strong processing and assembly technology, which can ensure reasonable and even clearance, achieve higher volume efficiency, and will not produce friction due to the thermal expansion of gas. 4, the structure of the fan determines that the mechanical friction loss is very small. Since only the bearing and gear pair have mechanical contact, the rotor, housing and gear ring have sufficient mechanical strength. Safe operation and long life are the main features of fan products. Fan fan, exhaust fan, industrial ventilation fan, boiler induced draft fan, mine fan, etc. Fan is widely used in tunnels, underground garages, civil buildings, metallurgy, factories and mines and other places ventilation and fire high temperature smoke exhaust. According to different uses, commonly used fans can be divided into centrifugal compressors, power station fans, ordinary centrifugal fans, ordinary axial flow fans, Roots fans, sewage treatment fans, high temperature fans. Mine fans can be divided into main fans, auxiliary fans and national fans according to their different uses. The main fan is used for ventilation of the whole mine, the auxiliary fan is used for air volume regulation of one branch of the ventilation network, and the ventilator fan is used for ventilation of local locations, which can be divided according to principle. It can be divided into centrifugal fans and axial flow fans. The above introduction is the fan characteristics. For more information please feel free to contact us!
