Product Description:

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:Fence material outside the plastic inside is iron or steel this material called
Ordinary steel profiles will be deformed, the color is relatively monotonous, usually white, if you want to change the color will add PVC with the film, a long time the PVC film will fade. Automotive supplies industry in the use of steel, the material requirements are relatively high, the most typical is the engine chassis protection board, has been widely used by most riders. Plastic steel is also used in the production of tapered roller bearing cage. Plastic cage has: 1, reduce the friction and roller slip, reduce the working temperature; 2, improve safety and performance; 3, fail safe mode, not stuck.
Q:Plastic doors and windows and plastic windows do not like?
Plastic doors and windows that use U-PVC plastic profiles made of doors and windows. Plastic doors and windows with wind, water, insulation and other good features. Plastic doors and windows are made of steel and steel profiles of doors and windows, steel profiles are made of plastic and steel profiles made of mixed.
Q:Plastic doors and windows profiles
The inherent quality of the profile and its reasonable structural design are the prerequisites for the manufacture of high-performance plastic windows. First of all, there must be good formula and high-quality raw materials and advanced production technology to ensure the quality of profiles. In addition from the structure of the profile of a single cavity and multi-cavity PVC plastic profiles, the cavity can be designed ribs, ribs, boss, etc., can be divided into two cavities cavity, three chamber or multi cavity, Can be better from the role of thermal insulation, on the other hand can make the cavity have different purposes, and some used to fix the rigidity of the steel lining, and some used to set the drainage chamber, and some internal ribs can be prevented Profile deformation, the inner ribs can improve the rigidity of the profile, increase the inertia moment of profiles, and improve the impact resistance of profiles.
Q:Steel windows and aluminum windows compare which is more expensive
Sound insulation performance: Aluminum windows and plastic window gap sealing level is basically the same, the sound insulation performance is basically the same.
Q:It is good for aluminum alloy
It is also good for aluminum alloy. The strength of the aluminum alloy is three times the strength of plastic, wind pressure strength than plastic two high. Aluminum alloy frame cross-sectional area of only steel 1/3, window frame weight is much lighter. Plastic doors and windows due to the strength of the material and low steel, although the steel lining by adding enhanced, but its wind pressure and watertight performance than the aluminum alloy window two levels. Just because the plastic window steel lining is not in its profile lap angle to connect the complete frame system, window frame, fan four corners and the T-shaped plastic angle of penetration is relatively low, so the high-rise buildings should be used with caution.
Q:Is the powder produced when the crushed plastic is crushed?
1, plastic shredders and power units to be installed firmly. If you need plastic crusher long-term fixed operation, it should be fixed on the basis of cement; if you need plastic crusher flow operation, the unit should be installed in the angle made of iron on the base, and to ensure that the power machine (diesel or motor) and plastic The pulley groove of the crusher is in the same plane of rotation. 2, after the installation of plastic crusher to check the Department of fasteners fastening, if loose to be given to tighten. Also check the belt tightness is appropriate. 3, plastic shredder before starting, first hand rotation of the rotor, check the claws, hammer and rotor operation is flexible and reliable, broken room with or without collision phenomenon, whether the direction of rotation of the rotor and arrows in the same direction, Plastic crusher lubrication is good. 4, do not casually replace the pulley, to prevent the speed is too high to cause the explosion chamber explosion, or too low speed affect the efficiency of the pulverizer. 5, plastic shredder should be maintained after the first start idle 2 ~ 3min, no abnormal phenomenon after feeding work. 6, the work should always pay attention to the operation of the plastic crusher, first of all, to be uniform to prevent the blockage of waste room; Second, do not work for a long time overload. If you find a vibration, noise, bearing and body temperature is too high, such as spraying out of the phenomenon, should immediately stop checking, troubleshooting can continue to work.
Q:Is not aluminum alloy better than steel?
Plastic shortcomings: Each product has its shortcomings, with the extensive use of steel profiles, some shortcomings also will be exposed. China's steel profiles most of the poor quality of the use of lead salt stabilizer, finished lead content between 0.6% -1.2%. Lead is a harmful substance to the human body, when the poor quality of aging, will precipitate lead dust, long-term exposure will lead to excessive lead in the blood, and even lead poisoning. The recent introduction of calcium and zinc and organic tin solution to solve the product contains Lead problems, but because of price reasons and technology immature, there is no large-scale application.
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:How plastic embossed profiles are made
Preloading To improve the quality of the product and improve the molding efficiency, the powder or fibrous molding compound is pre-pressed into a certain shape.
Q:Will the model of steel profiles (such as 88-type extrusion profiles, 80 extrusion profiles) is based on what to develop ah
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.
