Product Description:

Axial fan is a national committee to promote the use of a mechanical efficiency low-pressure ventilator, the aircraft low power consumption, low noise, and has excellent corrosion resistance and other characteristics. Can be used as industrial plant, machinery manufacturing, chemical industry, printing and dyeing, electroplating, pharmaceutical and other industries; theaters, hotels, office buildings, residential and other buildings. If wind shell removed. Also for their fan, but also in a longer exhaust pipe, installed in series interval, and to increase the total pressure of the pipeline.

(B) Fan Type:

T35-type axial fan impeller diameter divided according to the size NO2.8, NO3.15, NO3.55, NO4, NO4.5, NO5, NO5.6, NO6.3, NO7.1, NO8, NO9, NO10 , NO11.2 thirteen machine number, number of leaves of each machine number are for four. Leaves can be loaded into a 15 °, 20 °, 25 °, 30 °, 35 ° five kinds of angles. Therefore, since the size of each machine number of the blade installation angle, rotating speed of the spindle is different from the fan air pressure, air volume, and power consumption is not the same. (See performance table specific performance)

Transmission: selection of each pole motor with impeller directly coupled, the body shell made of a cylindrical shape, the direction of rotation is clockwise (viewed from the motor direction).

Fan selection table (performance table)

T35-type axial fan performance and choice of performance tables, refers to the standard conditions (temperature of 20, 50% relative humidity, atmospheric pressure 760 mm Hg, gas specific gravity 1.2 kg / m3) of air performance. When the rotor speed is changed, the fan can be converted following formulas:

Axial Fan Maintenance

1, the fan should be carefully checked before installing it because of packaging, transportation and damage, deformation, can be repaired properly after installation. The installation should pay attention to check the availability of loose coupling portion, blade and duct clearance should be uniform, not collide.

2, connecting the outlet of the pipe weight should not be borne by the fan duct, the installation should additional support.

3, in the axial fan air inlet end device must be installed set and installed protective barbed wire.

4, the fan base engaged with the ground plane must naturally not be forced to beat a bolt connection, to prevent deformation of the base. When you install the application level gauge calibration base, padded in order to maintain its horizontal position, and then tighten the bolt facilities.

5, the axial fan hoisting allowed to use, after installing wire transfer must first trial.

6, after a long time fan of unused, re-use, you must first check whether the prison because each coupling portion and reliable, and after the test run before the official use.

7, after the formal operation of the fan, once a year to check for loose screws, wires epidermis is damaged, repaired according to their specific circumstances.

8, always pay attention to the fan is in operation without abnormal noise, vibration is increasing, and timely inspection repair.

Q:What is the quality of plastic steel profiles in the end?
Quality in general, market acceptance can be, but the price is relatively high.
Q:PVC plastic profiles dip in the seam, how to deal with seamless docking
Fill too much for the current market price of profiles is low, and the pattern of rising raw material prices, profile manufacturers are to reduce the cost of the article, the formal profile manufacturers through the optimal combination of formula is not to reduce the quality of the premise, Cost; some manufacturers are in reducing costs while also reducing the quality of products. As a result of the ingredients of the formula, the most direct and effective way is to increase the filler, in the PVC-U plastic profile commonly used filler for the calcium carbonate. Most of the previous formula system is to add heavy calcium, the purpose is to increase the rigidity and reduce costs, but the calcium particles because of their irregular shape and relatively thick particle size and PVC resin body compatibility is poor, so the number of its added Low, and the number of copies will increase the color and appearance of the impact. Now with the development of technology, most of the use of ultra-fine light activated calcium carbonate, and even nano-calcium carbonate, which not only play a role in increasing rigidity and filling, but also has the role of modification, but its filling is not Infinitely, the proportion should be controlled. Now some manufacturers in order to reduce the cost of calcium carbonate added to 20-50 copies, which greatly reduces the physical and mechanical properties of profiles, resulting in this chapter referred to the phenomenon of brittle profile.
Q:Plastic steel profiles how to open V mouth
Plastic profile V-head saw is mainly used for steel-type 90-degree V-mouth cutting, the internal equipment by the two motors, two pieces of blade. Start the V saw when the two motors at the same time driving into a 90 degree saw blade, the steel profile cutting a 90 degree V port. Saw the saw speed, saw no burr, smooth surface. easy to use. The equipment is running smoothly. High precision. The depth of the V-shaped steel profile is half of the large surface height of the stitch (welding flux).
Q:How many meters of a conch plastic steel profile
You ask what is the use, to do is to open the window or push and pull, and generally 6 meters large amount of work can go to the factory to ask them how long pull
Q:What belongs to plastic profiles
Plastic Profile A: Impact modifier Plastic profiles, such as without impact modifier, plastic profiles will be very brittle, slightly collision, easy to break. Plastic profiles used in the production of anti-impact agent modifier mainly by the following three categories: chlorinated polyethylene, polyacrylates, ethylene - vinyl acetate copolymer. Plastic profile additive two: heat stabilizer Plastic profile is a thermosensitive plastic, so in the production and processing of plastic profiles, heat stabilizer is essential. The metal salt in the heat stabilizer absorbs the HCL from the PVC, so it can delay the decomposition rate of the plastic and prolong the decomposition time. The most commonly used in the production of plastic profiles is the compound lead salt, which has high thermal stability and low cost. Plastic profile additives three: lubricant The main role of the lubricant is to reduce the polymer and processing equipment and polymer molecules between the internal friction between the friction caused by excessive heat caused by resin degradation, improve the efficiency of heat stabilizer.
Q:What is the material of steel
Plastic steel profile referred to as steel, the main chemical composition is PVC, it is also called PVC profiles. Is widely used as a new type of building materials, because of its physical properties such as rigidity, flexibility, corrosion resistance, excellent anti-aging properties, is usually used as copper, zinc, aluminum and other non-ferrous metals excellent substitutes.
Q:How plastic embossed profiles are made
Plastic processing is a complex process, generally divided into the following main processing methods:
Q:PVC extrusion profiles compared to ABS, PE and other plastic profiles have any advantages?
PVC extrusion profiles compared to ABS, PE and other plastic profiles have any advantages? PVC is PVC, PVC in all plastics, the price is the cheapest, the advantage is cheap, toughness is better, the disadvantage is PVC Resin powder can not be used directly, but to add the relevant additives and stabilizers and auxiliary materials into, and then to produce products, the extrusion screw and barrel have special requirements. Because the plasticization of the relationship, so the equipment targeted.
Q:How to identify the installation of plastic or plastic
Plastic steel because there are iron, so use the magnet to identify. Another: steel easy to change line, now mostly switch to color steel or better.
Q:Is not aluminum alloy better than steel?
Aluminum alloy steel has its own advantages and disadvantages, in general, aluminum alloy is better than steel, high grade. Steel is hard plastic squeeze into the cavity, then will be coupled with the steel lining, which see the strength of the manufacturers of doors and windows, and if the thickness of the steel lining is not enough, a long time will be deformed, but the price is low, because it is plastic So it is not a special heat. Aluminum alloy must be a new type of aluminum, not the kind of the oldest kind of aluminum, the new aluminum cavity and plastic steel is the same, but the material is aluminum, good age, metal is hot fast, but It is also possible to add a kind of insulation material, cold bridge (also called broken bridge), plus this material can solve the problem of insulation, but also can do both positive and negative colors , Aluminum alloy is the high price of the general high-end district are equipped with aluminum alloy.
