Mine Main Ventilation Fan

Mine Main Ventilation Fan:

Mine main ventilation fan, The motor applied for the DK series counter-rotating main ventilator is usually a Y series three-phase asynchronous motor with a rated voltage of 380V and a protection class of IP54 (ie closed type), which can be fully adapted to the direct drive and installed in the mine to transport the air containing gun smoke, dust and the air with high humidity.

DK series counter-rotating main ventilator is specially designed according to the needs of various non-coal mine ventilation, such as metallurgy, nonferrous metals, gold, chemicals, building materials and nuclear industry, etc, which can be used as main fan and auxiliary fan. It can be installed on the surface or in the underground, suitable for the combined operation of multiple fans, which is an ideal machine station ventilator of various machine stations in the ventilation system of the multi-fan series multi-stage machine station. It is also suitable for the ventilation in large workshops, tunnels, civil air defense projects, etc.

Features

(1) The aerodynamic efficiency is high and the energy saving effect is extremely significant by using the twisted airfoil blades.

(2) With diverse performances and complete specifications, it can be well matched with various ventilation network of various kinds of air resistance and air volume type to maintain long-term and efficient operation.

(3) It is equipped with a steady flow ring device and the characteristic curve does not has the hump. There is not the risk of surge, so it can be operated safely and stably under any resistance state, and it is suitable for combined operation of multiple fans.

(4) It adopts the structure of direct connection between the motor and the impeller, so it has good overall stability, as well as can be installed conveniently and maintained easily with low device resistance. The transmission efficiency of it is higher than that of the belt and long shaft, without transmission failure and broken shaft risk. The mild foundation sinking and slipping will not affect the normal operation.

(5) It has a compact structure and good moisture resistance. The main body of the fan is adopted the steel plate and section steel block welding structure. The blade is made of steel plate material, which is hollow. The blade and overall strength is high and the ability to resist downhole blasting wave is strong. It can be installed on the surface or in underground, which is especially suitable as a machine station ventilator for the multi-stage station ventilation system.

(6) It can reverse the reverse wind and the wind reversal rate is greater than 60%. It is not necessary to build a reverse wind channel.

(7) The blade installation angle can be adjustable and the working condition of ventilator can be adjusted at any time according to the changes of the mine.

(8) The amount of civil works is small, so it can save a lot of investment.

(9) The noise is low.
