Danzhou G4-73 Performance Curve G4-73 Parameters Dehui Special Fan

The characteristic of this fan is that the main shaft speed is high, and in order to reduce the vibration of the machine body, the bearing box seats are low and in direct contact with the cement foundation seat. The transmission mode of this fan is: Type 4-6 adopts A-type bearingless box device, with electric motor directly connected transmission; № 7, 8, and 10 adopt D-type cantilever support devices, supported by rolling bearings, and connected to the motor with elastic couplings; Above No.12, an F-type double support device is used, supported by rolling bearings and connected to the motor with an elastic coupling.
Due to the different rotation directions of the impeller, this fan is divided into two types: right-handed and left-handed rotation. When viewed from one end of the motor, the fan with the impeller rotating clockwise is called a right-handed cyclone fan, represented by "right"; The machine that rotates counterclockwise is called a left cyclone machine, represented by "left" (in the external drawing, it represents the right)

Models 9-20-11 No. 4, 5, 6, 7, 8, 10, 12, 14, 16. The characteristic of ventilation fans is that they are all driven directly by electric motors. The spindle speed is high, and in order to reduce the vibration of the machine body, the bearing seats are all low and in direct contact with the cement foundation. The transmission mode of centrifugal fans is as follows: Type 4-6 adopts A-type bearingless box device, which is directly driven by an electric motor, while Type 7-16 adopts D-type cantilever support device, which is supported by rolling bearings and driven by an elastic coupling with the electric motor.
The 9-20-11 type fan has 12 blades, all of which are forward curved blades. The outlet height at the center is 30 degrees, and the circumferential speed of the impeller does not exceed 125m/s.

Models 9-04 and 9-06 series high-pressure small flow centrifugal blowers
1. Purpose:
In order to meet the needs of the development of power equipment in China, we have developed the 9-04 and 9-06 series high-voltage small flow centrifugal blowers, which have been successfully applied in the New North Thermal Power Plant and Panjin Oilfield. This blower is suitable for power plants, petroleum, environmental protection, aquaculture, metallurgy, ironmaking, and chemical systems. The temperature of the medium generally does not exceed 50 ℃ (not exceeding 80 ℃), and the dust and hard particles contained in the medium do not exceed 150mg/m3.

Model 8-18-101 high-pressure centrifugal fan is suitable for high-pressure forced ventilation of forging furnaces and certain equipment in general factories. It can be used as both input gas and transport material. It is suitable for discharging air or other non self igniting, non corrosive, and non viscous gases that are not corrosive to steel materials. The temperature of the exhaust air shall not exceed 80 ℃, and the dust and hard fine particles contained in the gas shall not exceed 150mg/m3.
