Features
The features of the DK series counter-rotating the main ventilator
(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 networks 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 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 is 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 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 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.
When used as the main fan and the station fan, the DK series counter-rotating main ventilator should be equipped with a special diffuser. The main fan on the surface shall be equipped with a diffuser to convert one part of the dynamic pressure into static pressure and reduce the dynamic pressure, and loss of the outlet, so as to achieve the purpose of energy saving. The ventilator installed in the well shall be equipped with a diffuser, which not only can reduce the local resistance coefficient, but also can reduce the dynamic pressure value of the diffuser outlet, thereby greatly reducing the local resistance of the fan device and saving ventilation power consumption.
All of the DK series counter-rotating main ventilators are equipped with special supporting diffusers. The flange of the diffuser is fixed to the flange of the fan outlet with the bolt.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.
The supporting special protection starter cabinet of the DK series counter-rotating the main ventilator
According to the needs of users, the ventilator of each specification can be supplied with a special protection starter cabinet when it is delivered from the factory. The electronic control device can reliably protect the motor from the faults, such as overload, voltage loss, short circuits, etc. A device that can quickly reverse the motor is set for it. When the ventilator is required to reverse the inverted wind, press the stop button first, and then press the reverse button after the ventilator stops.Product Parameters

Our company has introduced the latest research results of the Chinese Academy of Sciences, C4-II ternary flow wing twisted blades, which have high aerodynamic efficiency.
The surface of the ventilator impeller blade is sprayed with advanced super-resistant (CN) metal material to form a wear-resistant, anti-corrosion protection layer on the surface of the blade. The wear resistance of the blade surface is 10 to 50 times higher than that of the ordinary carbon steel material, thereby greatly prolonging the service life of the blade.
After we have absorbed the advantages of many domestic blade structures, based on the optimal control theory of concentrated parameters and distributed parameters, adopting the advanced ternary flow theory of impeller machinery and perfect CAD design technology, through multi-parameter control by blade bending amount, this blade is a high-performance fan blade. It ensures that the ventilator is operating in a wide and efficient area on the premise of meeting the wind volume and wind pressure.
Our company adopts computer simulation calculation and quasi-ternary flow theory, we correct the blade shape and calculate coordinate parameters of its shape, then make the core mold and the external pressure mold of the blade, and the blades are formed by hot pressing. According to a large number of experiments, the tilting blade has a larger lift-to-drag ratio than the original organic blade type and is the best choice for the airfoil blade.
The blades are welded with high-strength carbon steel material. The petiole is treated with high-quality carbon steel. So that the blade maintains the strength and rigidity of the steel blade when ensuring the corrosion resistance and wear resistance of the blade. Moreover, it effectively protects the blade from corrosion resistance and wear resistance in a humid air environment, and improves the operating life of the ventilator.The surface of the blade is coated with a super-resistant (CN) metal material coating, which not only maintains the strength and rigidity of the high-quality carbon steel blade, but also effectively protects the blade from corrosion resistance and wear resistance in a humid air environment, and improves the operating life of the ventilator.
The petiole is forged and made of high-quality medium carbon steel, and the tempering heat treatment is performed. The root has enough transition arc to eliminate stress concentration, through reasonable and correct force analysis and calculation, the strength, and safety factor of the most dangerous section of the blade root is more than 6 times. And carry out 100% X-ray non-destructive testing for welding seams of the blade root section and the blade, and all the defects were eliminated. Therefore, the impeller has a high degree of operational safety. Since the supply of the ventilator produced by our company, there has never been an accident of the petiole breaking and flying blades.
The impeller hub is made of high-quality steel and then tempered to process heat treatment. The surface of the hub is processed into a spherical shape, the petiole hole is placed at the thickest part of the center of the rim, which reduces the friction loss of the wind flow and ensures that the force-bearing section of the hub has sufficient tensile strength and rigidity. The welded joints of the hub all adopt groove welding and carry out 100% X-ray non-destructive testing for welding seam, which ensures the safe operation of the impeller.
After the blade is formed, first sandblasting is performed to remove dirt on the surface of the blade such as welding slag and oxide layer, to show the original color of the metal; Then, using the latest international inverter pulse arc power supply and high-speed arc spray gun to paint the super-resistant (CN) metal material on the surface of the blade, to form a wear-resistant anti-corrosion protection layer on the surface of the blade. Compared with the traditional arc spraying equipment and spraying process, the coating is denser, the ultra-resistant (CN) metal material has higher bonding strength with the blade's basic body, and the service life is longer.Company Profile
