Description
Technical field:
The utility model relates to a kind of high-efficient low-noise mine flame-proof type axial flow booster.
Background technique:
At present, the mining axial flow booster ubiquity efficient of domestic production is low, noise is big, the power consumption volume is big, shortcomings such as the impeller diameter ratio is quite big make that performance constantly worsens after entering the zone of high pressure, and the performance range of application is very narrow, separation point and best efficiency point are very approaching, have brought very big obstacle and just give in the actual engineering under the prerequisite that requires broad operating range.
Summary of the invention:
The purpose of this utility model is to overcome above-mentioned shortcoming, and a kind of high-efficient low-noise mine flame-proof type axial flow booster is provided.It has solved problems such as existing fan efficiency is low, noise big, power consumption.The purpose of this utility model is achieved in that high-efficient low-noise mine flame-proof type axial flow booster is made of: slip ring, flange, hub, impeller, motor front cover, guide plate, guide shell, motor shaft, motor, back end cover for motor, casing, terminal box, adpting flange, baffler.Slip ring is installed in the front end of impeller, hub is sleeved on the outside of impeller, and be fixed together by flange and slip ring, impeller is installed on the motor shaft, and the front end of motor shaft is equipped with the motor front cover, and back end cover for motor is equipped with in the rear end of motor shaft, guide plate is welded between guide shell and the casing, terminal box is installed in motor rear end and covers, and motor is installed in the guide shell, and baffler and casing link together by adpting flange.This product is energy-conservation, efficient, low noise, volume is little, simple in structure, be easy to transportation, install, easy to maintenance, especially this fan total efficiency is up to 88-89%, exceed other product 8-12 of the same type percentage point, and separation point and best efficiency point differ bigger, make this ventilator in actual engineering, have comparatively broad operating range, ratio A sound level LSA≤27 of noise are significantly less than the regulation of NBS than A sound level LSA≤35.
