Description
Technical field
The utility model relates to field of ventilation equipment, particularly a kind of glass fibre reinforced plastics centrifugal blower.
Background technique
Glass fibre reinforced plastics centrifugal blower is the blower fan be made by glass steel material, is also anti-corrosive centrifugal fan.General glass fibre reinforced plastics centrifugal blower can be used in the occasion of the gas that is corrosive, and discharges mordant gas.Its gas carried be do not allow to be less than or equal to 150mg/m3 containing stickum, contained dust and hard particles, gas temperature is less than or equal to 60 degree, relative moisture is less than or equal to 100%.High temperature place is not suitable for using glass fibre reinforced plastics centrifugal blower.Glass fibre reinforced plastics centrifugal blower is widely used in the occasion containing corrosive gas such as chemical industry, plating, oxidation, power station, laboratory, circuit board, environmental protection equipment.
Glass fibre reinforced plastics centrifugal blower working principle is when electric machine rotation drives blower fan wind wheel to rotate, gas between wind wheel Leaf also and then rotates, and throw away these gases under the influence of centrifugal force, gas flow rate increases, make gas, in flowing, kinetic energy is converted to static energy, then along with the supercharging of fluid, static energy is made to be converted to again speed energy, by exhaust outlet Exhaust Gas, and certain negative pressure is defined in the middle of wind wheel, because intake grill is negative pressure, ambient atmos is filled under atmospheric pressure immediately, constantly discharge under the effect of wind wheel continuous rotation and fill into gas, thus reach the object of continuous blast.Under Same Efficieney, blast and the general journey inverse ratio of air quantity.Under Same Efficieney, blast is high, and air quantity will be relatively low, and air quantity is large, and blast will be lower, so just can make full use of effect rate of motor.
The spiral case of existing glass fibre reinforced plastics centrifugal blower is generally fixed in frame, can not relatively rotate between spiral case and frame, make the exhaust outlet of spiral case can only towards a fixing direction, different glass fibre reinforced plastics centrifugal blowers must be customized in the place of different structure feature, the poor universality of glass fibre reinforced plastics centrifugal blower, customization needs to expend higher cost.
The spiral case intake grill of existing glass fibre reinforced plastics centrifugal blower is also had generally to be connected with other ventilation duct by bolt, because the bolt head of bolt is exposed in spiral case when connecting, for preventing corrosion, the etch-proof plastic bolt of customization need be used, but the intensity of etch-proof plastic bolt is low, easily there is fracture.
Also have the exhaust outlet of spiral case of existing glass fibre reinforced plastics centrifugal blower to be generally to expose completely, this makes some foreign material or rainwater enter in spiral case from exhaust outlet, threatens to the use safety of glass fibre reinforced plastics centrifugal blower.
