1、 The purpose of the fan:
The 4-68 centrifugal fan (hereinafter referred to as the fan) can be used for general ventilation and air exchange. The usage conditions are as follows:
1. Application: As an indoor ventilation system for general factories and large buildings, it can be used as both an input gas and an output gas.
2. Types of gases transported: air and other non self igniting, harmless to the human body, and non corrosive to steel materials.
3. Impurities in gas: There should be no viscous substances in the gas, and the dust and hard particles contained should not exceed 150 milligrams per cubic meter.
4. The temperature of the gas shall not exceed 80 degrees.
2、 Type of fan:
1. This fan is designed for single suction, with twelve machine numbers including No. 2.8, 3.15, 3.55, 4, 4.5, 5, 6.3, 8, 10, 12.5, 16, and 20.
2. Each type of fan can be made into two types: right rotation or left rotation. When viewed from one end of the motor and the impeller rotates clockwise, it is called a right rotation fan, represented by "right". Rotating counterclockwise is called a left rotating fan, represented by "left".
3. The outlet position of the fan is represented by the angle of the air outlet of the casing. Both "left" and "right" can be made into six angles: 0o, 45o, such as 135o, 180o, and 225o.
4. The transmission mode of the fan: There are four types: A, B, C, and D. Type 2.8-5 adopts Type A, which is directly driven by an electric motor. The impeller and casing of the fan are directly fixed on the motor shaft and flange (D2/T2 type for electric motors); N06.3-12.5 adopts a cantilever support device, which is divided into two transmission modes: C-type (belt driven pulley on the outside of the bearing) and D-type (connected by a coupling for transmission); № 16 and 20 are B-type cantilever support devices, driven by a belt, with the pulley located in the middle of the bearing.
3、 Structural characteristics of the main components
The No. 2.8-5 of the 4-68 fan is mainly composed of impeller, casing, air inlet and other parts matched with a direct connected motor. In addition to the above parts, there is also a transmission part for № 6.3-20.
1. Impeller: consisting of 12 backward sloping wing shaped blades welded between a conical wheel cover and a flat disc. All are made of steel plates and have undergone static and dynamic balance correction, with good air performance, high efficiency, and smooth operation.
2. Shell: The shell is a snail shaped body welded from ordinary steel plates. There are two different types of shells, numbered 2.8-12.5. The shell is made as a whole and cannot be disassembled. The shell of No. 16 and No. 20 is made into a three open type, with the upper half divided into two halves along the vertical centerline, in addition to being divided into two halves along the horizontal plane, and connected by bolts.
3. Air inlet: Made into a convergent streamlined overall structure, fixed on the inlet side of the fan with bolts.
4. Transmission group: composed of main shaft, bearing box, rolling bearings, pulleys or couplings, etc. The spindle is made of high-quality steel. Four fan numbers, numbered 6.3-12.5, have an overall bearing box structure with temperature gauges and oil gauges installed on the bearings. Fans numbered 16 and 20 use two parallel bearing seats with temperature gauges installed on the bearing seats and lubricated with bearing grease.
