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: Plastic doors and windows and plastic windows do not like?
- Glass fiber reinforced plastic (FRP) doors and windows 1) abroad to alkali-free glass fiber reinforced, the product surface finish is better, no need to deal with the system can be used directly to the window. Domestic self-developed glass fiber reinforced plastic doors and windows profiles generally with alkali glass fiber reinforced, the surface of the profile after grinding, available electrostatic powder coating, surface coating and other technical processes, access to a variety of colors or texture of the decorative effect. The following are the same as the " 2) Do not use high-alkali glass fiber made of profiles. The following are the same as the " 3) FRP doors and windows profiles have a high longitudinal strength, under normal circumstances, you can not enhance the steel. But the doors and windows size is too large or high wind pressure requirements, should be based on the use of requirements to determine the enhanced approach. The transverse strength of the profile is low. Fiberglass doors and windows frame for the assembly of the turret, the joints need to use sealant seal to prevent leakage of the gap.
- 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.
- 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: The state of high-rise residential building doors and windows materials are not allowed to use steel profiles are expressly provided?
- Plastic can not be used mainly to see its ability to withstand wind pressure can not meet the requirements, and the state did not force the request. At present, only Qinghai is limited to plastic steel, it is because the UV is relatively strong in Qinghai, steel weather resistance is not good aluminum. In fact, as early as ten years ago, steel doors and windows can be used in the tall buildings in Xiamen, indicating the use of absolutely no problem, provided that your doors and windows must be reasonable design, through the local fifty years once the wind. But also in the doors and windows production and installation process to comply with the specification.
- Q: The difference between steel and aluminum alloy profiles
- Plastic windows are easy to weather, aluminum alloy will not. If you want to be insulated when you do windows with double glass
- Q: How many meters of a conch plastic steel profile
- The length of the material factory standard is 6m Frame material is generally a bundle of four, or a bundle of six, the fan material is generally a bundle of 6-8, pressure line 20 - 30 bundle
- Q: What is the meaning of steel profiles 80?
- The so-called 88,80,60, refers to the bottom of the profile width. The unit is millimeter. The profile manufacturers have these specifications are refers to the bottom of the width is the same, but different manufacturers of profile height is not exactly the same
- Q: What is the difference between plastic doors and windows and steel doors and windows?
- According to the characteristics of profiles, the profiles are roughly divided into European and American two. European doors and windows of its characteristics are: profile formulations still use the traditional lead salt heat stabilizer, a small number of countries and enterprises began to use environmentally friendly organic tin heat stabilizer; main section of the profile profile is generally designed for three or four main chamber, The total number of chambers to 6 to 8, wall thickness is generally 2.5 ~ 3.0mm. Doors and windows with fan-fan frame structure, fan section larger, with pulley, can be removed; built-in glass, dry mosaic; window open in the foreign under the hanging window-based, a small amount of sliding window. 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.
- Q: The main features of steel profiles
- 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: How to identify the installation of plastic or plastic
- Through the cutting, welding, etc. made of doors and windows of the frame fan, equipped with sealing tape, tops, hardware and other accessories made of doors and windows, in order to enhance the rigidity of the profile, more than a certain length of the cavity need to add reinforced steel (steel Lining), this kind of doors and windows called plastic doors and windows.
