Which is better the quality of Boiler Fan

G4-73, Y4-73 centrifugal fan Profile G4-73 and Y4-73 boiler-Fan is suitable for power plant 2-670t / h steam boiler-Fan system, which G4-73, Y4- 73 type NO20-31.5F centrifugal-Fan is 100,000-200,000 KW thermal power generating units supporting, in the absence of other special requirements, G4-73 can be used for mine ventilation and general ventilation. Fan transmission medium is air, the maximum temperature not exceed 80 ℃, medium induced draft fan for transporting gas, the maximum temperature must not exceed 250 ℃. G4-73 type and Y4-73 Centrifugal-Fan are single suction intake, the support they have two ways: a cantilever support (D type) and double support (F-type). The former machine number there is NO: 8,9,10,11,12,14,16,18,20,22,25,18,29.5 other 13 kinds, which have 20,22,25,28,29.5 machine number, 31.5 of six. Each fan can be made of the right-handed or left-handed forms. Look from the motor direction of rotation of the impeller, impeller rotates clockwise, said right rotation fan, said the counter-clockwise rotation of the fan left. Changzhou (Wuxi) Co., Ltd.
