Quality Centrifugal Flow Fan & Industrial Centrifugal Fans Factory

On Aug 26th, the cracking furnace fans ordered by users in Kazakhstan were successfully delivered. There are 9 fans in this shipment, of which 6 fans are used for the gas generated by the pyrolysis furnace and conveyed under pressure. Inflammable and explosive gas, so there must be no leakage. According to the working conditions and specific requirements, we have thickened the fan, and the sealing device adopts a mechanical seal to ensure that the position where the main shaft and the casing are in contact will not leak gas. The transportation adopts frame packaging, which can effectively avoid bumps during loading and unloading. SIMO Blower’s industrial centrifugal fans can be widely used in various industrial systems, such as power generation, metallurgy, cement production, chemical industry , waste incineration systems, Industrial boiler systems, etc. Choose SIMO Blower, we will serve you wholeheartedly.

Centrifugal fans will wear due to long-term use during the application process. How to avoid the wear of centrifugal fans? First of all, we need to know that the wear of the centrifugal blower will be in many different positions, so different anti-wear measures need to be taken for them. At first, it’s necessary to do a good job on the blade surface. The common advantages of carburizing, plasma surfacing, spraying cemented carbide, and pasting ceramic sheets are to increase the hardness of the blade surface, which in turn improves the wear resistance of the blade to a certain extent. These methods are easy to use and low cost, but the coating wears quickly, and one treatment can last for 3 to 5 months. For blade wear, the impeller wear can be reduced to a certain extent by improving the blade structure, processing the working surface of the blower fan blade into a serrated shape, changing the hollow blade into a solid blade, and adding welding anti-wear blocks to the blade. Install the anti-wear cascade, and install the anti-wear cascade at the most easily worn place, which can prevent the particles from flowing to the rear disc and the blade root. In addition, the shape of the air inlet of the centrifugal fan should be selected reasonably, and the minimum inlet relative speed of the impeller should be ensured during the design, the number of revolutions of the fan should be reduced as much as possible, and the appropriate shape of the impeller flow channel should be selected.

The function of the damper is to pre-rotate the air to make the air flow into the impeller more smoothly. If a left-handed damper is installed on a right-handed fan, the wind will directly impact the blades, which is mainly manifested as overshoot load and strong vibration, if the damper is fully open, the current will rise straight, and in severe cases, the motor will burn out.     Today I will share with you how to distinguish the rotation direction of the damper. Let’s first look at this horizontal damper. First, we need to find the support rod of the damper as the base point (or take the air intake direction as the base point), and then observe the rotation direction of the linkage handle from fully closed to fully open, clockwise rotation is right rotation, counterclockwise rotation is left rotation.     How to distinguish the rotation direction of the damper installed on the fan? First, we stand on the motor side and observe the direction of the handle from fully closed to fully open (the direction of the switch will also be marked on the damper to help us better distinguish), clockwise rotation is right, and counterclockwise rotation is left.   Just I shared is the method of distinguishing the rotation direction of the petal-type damper. The common forms of the damper are single-plate, three-plate and louver. Among them, the single-plate and three-plate are not divided into rotation directions, and can be installed directly according to the direction of the air intake. Regarding the shutter-type damper, if you need to know more about it, you can contact us. https://www.youtube.com/watch?v=mUZxYOZKRNI&t=39s

Impeller is the heart of centrifugal fan. Different working conditions have different requirements for impeller forms of centrifugal fans. According to the blade Angle of impeller outlet, it can be divided into three types: forward type, radial type and backward type. Forward type blade, blade outlet Angle β2 > 90 °, the export of wind pressure is higher, but the efficiency is low, the forward type blade easily gathered impurities between the impellers, easy fouling, used for air flow, but requires higher area, wide application, blade generally narrower, quantity, type common to fan model has 9-10 series, 9-08 series high pressure fan.     Radial blade: the outlet Angle of the blade β2=90°, it has simple structure, low production cost, parameters between the forward type and the back type, low efficiency, because of its characteristics of not easy to scale, it is more used in the mine and heavy dust conditions. Backward blade: blade outlet Angle β2

Centrifugal fans can withstand the high temperature flue gas below 1000 degrees.     High temperature fan is a general name for a class of fans, suitable for conveying high temperature gas with slight corrosion, non-spontaneous combustion and working temperature below 1000℃. The dust content of medium should be less than 150mg/m3. It is widely used in chemical petroleum, metallurgical iron and steel, building materials, cement, environmental protection and other fields. According to the high temperature resistance level can be divided into four levels: one 80℃-300℃, two: 300℃-450℃, three: 450℃-600℃, four: 600℃-1000℃. In the design and selection of high temperature fan, the change of gas density under high temperature gas, the dimension expansion coefficient of fan components, and the selection of high temperature resistant materials should be fully considered. Different materials are classified as follows: FIBERglass: ≤100℃, carbon steel (Q390, Q460, HG785) : ≤500℃, stainless steel (304, 316L, 310S), dual-phase stainless steel 2205: ≤1000℃. High temperature resistance at the same time also consider the corrosive gas of high temperature flue gas, choose high temperature and corrosion resistant high quality materials. With the development and application of new technology and the continuous progress of high temperature resistance technology, high temperature fans will be applied in more industries and fields in the future, and high temperature fans will also provide more complete solutions for more industries.

Summer is rapidly becoming a memory, because there is no clean beach for visiting, at the weekend. “Beach litter is a serious environmental problem,” said Charlotte Coombes, Beachwatch Officer for the MCS. And it has becoming an international problem. More and more people take part in Environmental protection activities. That how to deal the rubbish has paid more attention. Rubbish is a kind of resources which was putted in wrong place. More people are considering the re-use of this resources. Electricity Power production has become the essential way to solve the garbage incineration. After negotiate with Vietnam customers on 13th January 2016, they visited SIMO BLOWER’s factory.
