2. Direct-coupled glass fiber reinforced plastic negative pressure fan: There are three types of direct-type motors: 12-pole 450 rpm, 10-pole 560 rpm, and 8-pole 660 rpm. The 12-pole motor has the most applications, and the fan with high speed has a large noise. New year
Glass fiber reinforced plastic negative pressure fan is a new type of ventilation equipment made of glass fiber reinforced plastic material. Because the outer frame of the fan adopts anticorrosive glass fiber reinforced plastic material, the reason is to use negative pressure for ventilation, to achieve the purpose of smooth air, ventilation and cooling, so it is called FRP negative pressure fan FRP negative pressure fan has the characteristics of corrosion resistance, large air volume, low energy consumption, low speed, low noise, etc.
Divided from indecent appearance
1. Flare-shaped glass fiber reinforced plastic flared negative pressure fan. The exhaust of the fan is indecent like a horn shape. Many people are called flared glass fiber reinforced plastic negative pressure fans. The sizes are large and small: 146 * 146cm, 126 * 126cm , 106 * 106cm, etc.
2. Square glass fiber reinforced plastic negative pressure fan. The fan as a whole looks square, so it is called a square glass fiber reinforced plastic negative pressure fan. The sizes are: 130 * 130cm, 113 * 113cm, 98 * 98cm, 80 * 80cm, etc.
Divided from the transmission essentials
1. Belt-type glass fiber reinforced plastic negative pressure fan: belt-type speed is 370-450 rpm, adopting six-pole or four-pole aluminum shell motor protection grade IP55 F-class insulation, products with low speed have relatively low noise
Glass fiber reinforced plastic negative pressure ventilates the factory. The negative pressure exhaust fan of the factory exhausts the air to reduce the indoor air pressure. The indoor air becomes thinner and forms a negative pressure zone. The air flows into the room due to the difference in air pressure. Air fans are centrally installed on one side of the factory building, and the air inlet is on the other side of the factory building. The air flows from the air inlet to the negative pressure fan to form a convection blower. During this process, doors and windows close to the negative pressure fan are kept closed, forcing the air from The doors and windows on the side of the air inlet compensate for the inflow of air flowing into the workshop in an orderly manner. The air flows into the workshop from the air inlet, flows through the workshop, and is exhausted by the negative pressure penetrating fan in the workshop. The ventilation is complete and efficient, and the air exchange rate can reach 99%. Through detailed engineering design, according to the necessary design ventilation rate and wind speed, any high heat, harmful gas, dust and smoke can be quickly discharged from the workshop, and any problem of poor ventilation can be completely handled within a few seconds from turning on the exhaust fan. To achieve the effect of ventilation
Application scope of FRP negative pressure fan:
A. Suitable for high temperature or smelly workshops: such as heat treatment punishment factory, casting factory, plastic factory, aluminum factory, shoe factory, leather factory, electroplating factory, various chemical factories
B. Applicable to labor-intensive enterprises: such as clothing factories, various equipment workshops, and Internet cafes
C, horticultural greenhouses, large greenhouses, ventilation and cooling, livestock pastures
D. It is especially suitable for places that need to cool down and have necessary humidity, such as cotton spinning factories, wool spinning factories, hemp spinning factories, weaving factories, chemical fiber factories, warp knitting factories, texturing factories, knitting factories, silk factories, socks factories, etc. Textile mill
Features of FRP negative pressure fan: 1. The aluminum-dedicated fan motor used in the advanced technology from foreign countries has a long application life, stable operation and low noise. 2. Adopt 500 years of non-differentiated FRP (glass fiber reinforced plastic) as the fan casing material, which is resistant to acid and alkali. , Anti-corrosion, no rust, long service life, etc. At the same time, it can reduce the signs that can resonate due to the large number of metal materials in the whole machine. 3. According to fluid dynamics (coquetry), use CAD / CAM to optimize the design and manufacture angles. The blades with reasonable air volume and noise are made of glass fiber reinforced plastic as the material of the blade. They do not age and change shape. The matched motor is only 0.75KW4. It is designed and manufactured by using the principle of air downstream, which does not require electrical energy, automatic switching, and rainproof pneumatic Blinds
