DK series counter-rotating the main ventilator
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 a main fan and auxiliary fan. It can be installed on the surface or underground, suitable for the combined operation of multiple fans, which is an ideal machine station ventilator for various machine stations in the ventilation system of the multi-fan series multi-stage machine station. It is also suitable for ventilation in large workshops, tunnels, civil air defense projects, etc.
The features of the DK series counter-rotating the main ventilator
(2) With diverse performances and complete specifications, it can be well-matched with various ventilation networks of various kinds of air resistance and air volume types to maintain long-term and efficient operation.
(3) It is equipped with a steady flow ring device and the characteristic curve does not has a hump. There is no risk of a surge, so it can be operated safely and stably under any resistance state, and it is suitable for the combined operation of multiple fans.
(4) It adopts the structure of a 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. Its 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 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 are high and the ability to resist downhole blasting waves are strong. It can be installed on the surface or underground, which is especially suitable as a machine station ventilator for the multi-stage station ventilation system.
(6) It can reverse the 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 the ventilator can be adjusted at any time according to the changes of the mine.
(8) The amount of civil work is small, so it can save a lot of investment.
(9) The noise is low.
