The fan is to rely on the input of mechanical energy, to increase the gas pressure of the gas feed side of the machinery. FRP centrifugal fan is made of glass fiber reinforced plastic material made of fans, also known as anticorrosion centrifugal fan.
Features
With strong corrosion resistance, long life, stable operation and other characteristics.
General FRP centrifugal fan can be used in the case of corrosive gases, emission of corrosive gases. It is not allowed to transport gas with viscous material, contained in dust and hard particles are less than or equal to 150mg / m3, the gas temperature is less than or equal to 60 degrees, the relative humidity is less than or equal to 100%. Not suitable for high temperature place FRP centrifugal fan.
Use
Widely used in the case of containing corrosive gas chemical, electroplating, oxidation, power plants, laboratories, circuit boards, environmental protection equipment.
Centrifugal fan and turbine compressor works basically the same, but due to the low gas flow rate, pressure changes little, generally do not need to consider changes in the specific volume of gas that the gas as incompressible fluid handling.
Centrifugal fan can be made righthanded and lefthanded two types. To face from the motor side, the impeller rotates clockwise rotation of the fan called right, rotate counterclockwise, called L.
Centrifugal fan is based on the principle of potential energy is converted to kinetic energy, the use of highspeed rotation of the impeller of the gas to accelerate, then slow down, change the flow, so that the kinetic energy is converted into potential energy (pressure). In the singlestage centrifugal fan, the gas enters from the axial impeller, changing the gas flow through a radial impeller, and then into the diffuser. In the diffuser, the gas flow direction changes caused by the deceleration, the decelerating effect of the kinetic energy is converted into pressure energy. Increased pressure occurs mainly in impeller, followed by the process occurs in the diffuser. In a multistage centrifugal fan, the air flow into the next with a reflux allows the impeller to produce higher pressures.
- Q: Will the model of steel profiles (such as 88-type extrusion profiles, 80 extrusion profiles) is based on what to develop ah
- Strictly speaking, refers to the width of the bottom of the window frame profile. 88 is that the bottom of the frame width of 88 mm. And some profiles are not absolutely accurate, take the approximate value
- 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: China 's top ten brands of steel profiles in 2014
- In the financial financial steel doors and windows is a national key high-tech enterprises, is the industry's well-known brands, the national one of the top ten brands of steel doors and windows, it has Zhejiang Zhongcai profile company production. A large multinational company headquartered in Germany. It is the international profile of the North New North new steel doors and windows is China's largest new building materials group. The company has created more than 30 years of history, it is also well-known trademarks in China. The market occupies a certain proportion.
- Q: The state of high-rise residential building doors and windows materials are not allowed to use steel profiles are expressly provided?
- Allows the use of steel profiles. The provisions of the doors and windows with the number of layers does not matter. Now energy-saving requirements, no matter what material, as long as the energy-saving requirements on the line. Aluminum need to use heat type, more expensive, so the use of steel is more common.
- 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.
- Q: The difference between steel and aluminum alloy profiles
- The quality of steel doors and windows is very difficult to identify, steel doors and windows of the steel liner standards should be GB 1.2mm, but you buy after the identification of its compliance, it is very difficult. But the broken bridge aluminum doors and windows in the identification of the quality is relatively easy, broken bridge aluminum window wall thickness standard is 1.4mm, the door profile thickness of 1.6mm, these thickness is on the surface can be Depending on the measured, so after the identification on the purchase, it is very easy. Another point to note is that no matter what kind of profiles you choose the doors and windows, we must focus on the strength of the manufacturers and workers of the technology, doors and windows performance is playing a good effect, depends entirely on the manufacturer's design, measurement , Installation and production. No matter what kind of profiles of doors and windows, to become a good door and window, are three points for seven installs. Obviously, the installation of technology is much more important than the type of selection.
- 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 is the meaning of steel profiles 80?
- Is the cross-section width of the profile, the insulating glass is not related to the profile, depending on the thickness of the profile, usually the 88 series of insulating glass should be thicker than the 80-shaped insulating glass.
- Q: It is good for aluminum alloy
- Aluminum alloy high temperature, non-flammable; is a good conductor, lightning can be anti-static; recyclable, environmentally friendly. Plastic is not high temperature, combustion; is the insulator, but need anti-static; degradation is slow, can not be recycled, slow combustion will release toxic gases, environmental impact.
- Q: Bathroom plastic door with what material to do
- 1 PVC plastic doors and windows 1) In all kinds of building windows, PVC plastic windows in saving energy production profiles, recycling of recycled materials and the use of energy consumption has a prominent advantage in the insulation and energy saving has excellent performance and low cost. 2) In order to increase the rigidity of the window, in the window frame, sash, the tread profile of the force bar, should be based on the strength of the wind pressure design and other requirements to determine what kind of reinforced steel. 3) Coextrusion of UPVC resin with colored polymethyl methacrylate (PMMA) or acrylonitrile-styrene-acrylate copolymer (ASA), as well as coating on white profiles, can be coated with a variety of textures and A variety of surface color decorative effect. In addition, UPVC resin powder is also added to the pigment mixture extrusion of the body dyeing technology. But there are still different views on this technology, it should be particularly careful in the selection, to check the kind of profiles by artificial accelerated aging test after the color changes. It is recommended to coat the color film with the color film to improve its weatherability.
