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:Plastic doors and windows profiles
Plastic doors and windows with its good insulation, insulation, sound insulation and corrosion resistance to become steel and wood windows of the alternatives, but because of the market is not mature, raw material prices soared and the price of the profile is soaring, making a lot of profiles manufacturers Not to sacrifice the quality of the material to reduce costs, in the profile by adding a lot of calcium carbonate or the use of low-cost raw materials additives, plastic window with poor quality hardware accessories, ultra-thin ribs plus rough manufacturing process, so low-performance products into After the market, to the user and the industry has brought a great negative impact, the long run, will repeat the sixties and seventies of the same mistakes.
Q:Plastic doors and windows and plastic doors and windows have anything to do
American doors and windows: the main formula for the use of environmentally friendly organic tin heat stabilizer, to avoid the production, processing, use of lead salt toxicity of the drawbacks; development for the multi-cavity section, the second is to reduce the profile wall thickness, 1.80mm; while increasing the number of internal reinforced steel and the chamber, the chamber generally have 9 to 13. In addition to reducing the strength of profiles, but also improve the thermal insulation and sound insulation effect. The sliding window for the frame package fan, improved the sealing and safety performance, cancel the fan pulley, reduce the fan section at the same time, the window lighting performance has been improved. Developed a standard installation method for pulling windows and new mounting wings. In addition the market has a total of steel and plastic doors and windows, plastic and steel machinery is a combination of new materials.
Q:What belongs to plastic profiles
Plastic profiles are used more: window frames, staircase handrails, troughs, wall feet, shaped tubes and so on. Raw materials are mainly hard PVC, a few are semi-hard PVC, soft PVC, polyurethane low foam and other materials. Plastic profiles with its excellent thermal insulation performance is listed as one of China's key development of building materials. In the production of plastic profiles, the need to pay attention to what problems in order to ensure the quality of profiles and technology.
Q:Steel windows and aluminum windows compare which is more expensive
Wind pressure strength and watertightness: Plastic windows due to the strength and rigidity of the material is low, although through the processing of steel to enhance, but its wind pressure and watertight performance than the aluminum window about two levels. Moreover, due to the steel window steel lining steel is not in its profile cavity angle into a complete frame system, window frame, fan four corners and T-shaped plastic welding angle strength is relatively low, according to the end of 1998 Shanghai enterprises inspection 425 Batch steel window three examples of the situation after the serious analysis of the "plastic window in the high - rise buildings should be used with caution.
Q:PVC plastic profiles dip in the seam, how to deal with seamless docking
Stabilizer too much or too little stabilizer is to inhibit the degradation, or with the release of hydrogen chloride reaction and to prevent the discoloration of PVC processing. Stabilizer according to the different types of different, but the total point, the amount of excessive will delay the material of the plasticization time so that the material export mold when the plastic is not, the formula system between the molecules are not fully dissolved, Its intermolecular structure is not strong cause. And the amount of too little will result in the formulation of relatively low molecular weight degradation or decomposition (also can be said to be plasticized), the stability of the intermolecular structure of the various components of the damage. So the amount of stabilizer will also affect the impact strength of the profile, too much or too little will cause the profile strength caused by the phenomenon of brittle profile.
Q:What is the steel profile?
GB 8814-2004 according to the thickness of the main section of the profile will be divided into three categories of ABC, according to the "visible wall thickness minimum / non-visible wall thickness minimum" said, A type of wall thickness of 2.8 / 2.5mm, B Type of material requirements wall thickness 2.5 / 2.0mm, C type of wall thickness does not specify the requirements. The mainstream of the national standard profiles are Class B.
Q:How many meters of a conch plastic steel profile
Plastic specifications of a lot of steel, do not know what you want to know? But each type of material has a standard weight of rice, their own to know, for example: Conch 60 two-track sliding box weight is 1.22kg, then 1000kg divided by 1.22 = 819 meters
Q:What is the broken bridge of aluminum? What are the characteristics?
Broken bridge aluminum energy saving and environmental protection: broken bridge aluminum aluminum-plastic composite window at the seams are equipped with multi-channel sealing tops or ternary ethylene rubber tape, air tightness for a level, can give full play to air conditioning, and save energy 50%.
Q:Plastic steel window profile material
GB 8814-2004 according to the thickness of the main section of the profile will be divided into three categories of ABC, according to the "visible wall thickness minimum / non-visible wall thickness minimum" said, A type of wall thickness of 2.8 / 2.5mm, B Type of material requirements wall thickness 2.5 / 2.0mm, C type of wall thickness does not specify the requirements. The mainstream of the national standard profiles are Class B.
Q:What is the material of steel
In the building construction is mainly used for sliding, sliding doors and windows, fence, pipe and ceiling material applications, through the new process is also widely used in automotive engine protection board, not only light weight, and good toughness, with just fine Nature, and sometimes also known as alloy steel.
