Product Description

 

K series ventilator for Coal mines

K series ventilator operates more efficiently with lower noise and greater performance range, and the power saving effect is more significant. At the same time, the main air tube is equipped with a steady flow ring device and the characteristic curve does not has a hump, which can ensure the ventilator operates safely and stably under any resistance state.

K series ventilator adopts the wheel ratios of 0.40 and 0.45 and single machine structure, which is divided into K40 and K45. K40 adopts 4, 6, and 8-pole motors with three kinds of rotation speeds respectively. K45 adopts 4 and 6-pole motors with two kinds of rotation speeds respectively.

The model representation method (for example) of the mining, the energy-saving ventilator is as follows:

 Mining ventilator
("DK")  ("DK" is the counter-rotating mining ventilator)
15,(D=15dr)   The machine number is 15 (ie the working wheel diameter D = 15dr)
d=0.40,"45"d=0.45    Hub ratio d=0.40, "45" is d=0.45
4,n=1450r/min ("6"6,n=980r/min;"8"8,n=730r/min)
The number of motor poles is 4, n=1450r/min ("6" is 6 poles, n=980r/min; "8" is 8 poles, n=730r/min)

K series ventilator is specially designed according to the needs of ventilation in non-coal mines, such as metallurgy, nonferrous mk, gold, chemicals, building materials, and nuclear industry, etc, which can be used as a main fan or an 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.

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 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 is high and the ability to resist downhole blasting wave 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.


Diffuser
When used as the main fan and the machine station ventilator, the K series mine energy-saving ventilator shall 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.
