Product Description
Brief Introduction of Yatai Typical Centrifugal Fan
DEF(DT) Series of Centrifugal Fan
Outline
The DEF series fire-fighting ventilation (dual purpose) low noise and cabinet centrifugal air blower is a kind of high efficiency fan which developed by Shanghai Traffic University and us, and has many advantages such as heatproof, novel, compact, light and vibrateless. It is ideal ventilation product applied in hotel, theatre, basement, factory and mining enterprise, office building and so on and a renewable product of fire fighting smoke exhaust fan in high level buildings. It has been best-sold in our factory and got a high praise.
Characteristics
(1)Compact and artistic. The body is assembled by frame and shook. The frame is stretched by a cold bending machine. The shook adopts duplicated board, the inner layer material noise elimination.
(2)For meeting the users' different installment need, provide different inlet and outlet direction. Uses the mold production, high precision, may assemble after broken up.
(3)The impeller, major component of air blower, is made by the mold completely based on absorbing the US LAU Industrial Corporation product. It is the multi-wing, forward strongly curved and has characteristics such as high efficiency, low noise, big volume, steady movement, stable quality and so on. The scroll is made of high quality galvanized sheet mechanically.
(4)The DEF series fire-fighting ventilation (dual purpose) low noise and cabinet centrifugal air blower is divided into A and B model. The A, motor outside the box, is used in fire fighting and smoke discharging; The B, motor inside, in taking a breath.
(5)The A fire fighting low noise cabinet centrifugal air blower, motor outside the box, isolated with the high temperature fume system to guarantee running more than 60 minutes continuously in 300ºC situations. Qualified by the National Fixed Fire Fighting System and Fireproof Component Testing Center. Its performance has achieved domestic leading level, approved by the Fire Fighting Bureau of more than 30 provinces.
(6)If the user needs big volume air blower, we can produce the parallel fire fighting and ventilation (dual purpose) low noise cabinet centrifugal one.
2. 4-72 Centrifugal Fan
F4-72 Non-corrosive Centrifugal Fan
B4-72 Explosion-proof Centrifugal Fan
Structure pattern
4-72 centrifugal fan is a kind of high effective energy saving one, its wing leaf blade, curved impeller and awl arc current collector make the fan have a fine lift-drag ratio.
In 4-72 fan, No. 2.8~6A fan is mainly composed of impeller ,cabinet, inlet and motor. No.8~10C,D also includes transmission, belt pulley and shaft coupling.
The rotation of 4-72 is divided into clockwise and counterclockwise, facing squarely from one side of motor, if the impeller revolves clockwise, the fan is called clockwise rotation one. If counterclockwise, counterclockwise one, expressed by "left". The rotation of the fan must be indicated when ordering.
The outlet position is indicated by the outlet of the cabinet. No. 2.8~6A is made into 1 kind of pattern when leaving the plant, the user may install according to the outlet position, no indication when ordering. No.2.8A outlet position may adjust from 0° to 225°, gap 45°. No.3.2~6A outlet position may adjust from 0° to 225°, gap 22.5°. No.8~12 0° to 225°,gap 45°,must indicate when ordering. No.16~20 has 3 kind of fixed angles: 0°, 90°,180°, cannot adjust when installs, must indicate when ordering.
The transmission of 4-72 fan has A,B,C,D 4 kinds. A:impeller and motor straight joint. B: leather belt, the belt pulley between two bearings. C: leather belt, the belt pulley is in the flank bracket outside of the bearing. D: shaft coupling transmission for the impeller and motor. No2.8~5A uses A type; No.6, A, C and D3; No.8~12, C and D2.
F4-72 fan is a derivation product from 4-72, made of glass fiber reinforced plastic material. Its metal parts are covered by anticorrosion level, and prevent corrosion effectively.
B4-72 fan is a derivation product from 4-72 too, is a special-purpose one for explosion situation. It has explosion-proof electrical machinery, the essential spare part uses static electricity surface layer and non-ferrous metal, can prevent friction static electricity and electric spark effectively.
The performance, selected parts and ground size of r4-72 are consistent with 4-72. The
B4-72 are consistent with 4-72. No2.8~6A uses B35 with flange plate and footing electric motor. The motor matched for No.6~12 C,D is corresponding with YB and B3 in Y series corresponding.
Note: The matched motor is three-phases.
Suitable Situation
4-72 centrifugal fan suits in ventilation, deliver or exhaust in all kinds of civil and industry architectures.
F4-72 anticorrosion centrifugal fan is suitable in chemical plant, laboratory, basement, bathing pool and so on, to convey caustic gas, acid or alkali gas and high-moisture gas.
B4-72 explosive-proof fan is suitable in boiler(oil or gas as fuel), highly concentrated dust workshop, fuel depot, gas storage stands, high explosive cargo warehouse and so on , this situation has the explosive-proof request, to transport the flammable, explosive and easy volatile gas.
