4-68 B4-68 explosion proof centrifugal fan Application
The 4-68 centrifugal fan can be used for indoor ventilation in general factories and large buildings. It can be used to input gas or output gas. The gas to be transported should be air not exceeding 80°C and other unnatural, harmless to humans, and non-corrosive to steel materials. The gas is not allowed to contain viscous substances, and the dust and hard particles contained are not more than 150mg/m2.
Type
Viewed from the side of the motor, the impeller rotates clockwise, which is called a right-handed fan, which is represented by "right"; when the impeller rotates counterclockwise, it is called a left-handed fan, which is represented by "left". The outlet position of the fan is expressed by the angle of the air outlet of the casing. Machine No. 2.8~6.3 All are made into one form when leaving the factory, and the user can install it to the required air outlet position according to the requirements, and there is no need to indicate when ordering; the adjustment range of the air outlet position of the machine number N08~12.5 is o°~22.5° , The interval is 45°; the air outlets of the machine numbers N016 and 20 are made of 0°, 90°, 225°, three fixed positions, which cannot be adjusted, and need to be noted when ordering.
There are four transmission modes of the fan: A, B, C, and D. No. 2.8-5 adopts A-type transmission, N06.3-12.5 adopts C and D-type transmission, and N016 and 20 adopt D-type transmission.
Structure
Type 4-68 fans with machine numbers N02.8~5 are mainly composed of impellers, casings, air inlets and other parts distributed direct-connected motors. Nc6.3~20 also have transmission parts in addition to the above parts.
(1) The impeller consists of 12 backward inclined wing-shaped blades welded between the curved wheel cover and the flat plate. They are all made of steel plate, and have undergone static and dynamic balance corrections. The air performance is good, the efficiency is high, and the operation is stable.
(2) The casing is a snail-shaped body welded by ordinary steel plates. The casing is made into two different types. The No.2.8~12.5 case is made as a whole and cannot be disassembled. The No16 and No. 20 casings are made into two-open type, divided into two halves along the horizontal plane of the middle division, and connected by bolts.
(3) The air inlet is made into a convergent line-shaped overall structure, which is installed on the side of the fan, and the cross-section parallel to the axial direction is a curved shape, which can make the gas enter the impeller smoothly, and the loss is small.
(4) The transmission part is composed of main shaft, bearing box, wave bearing, belt wheel or coupling.
Utilization of fan
Operation is permitted only when the fan is in perfectly normal condition.
It is required to check each part of the fan for normality in case of startup of the fan upon maintenance.
The fan shall be cleaned regularly and the dust, dirt and other impurities inside conveying pipeline shall be removed at regular interval to prevent rust.
It is not allowable to repair the fan when it is in operation.
A throttling device may be used for adjustment in case of excessive flow which not in compliance with operating requirements or smaller flow required in a short time.
The fan shall be immediately stopped for inspection in case of abnormality during its startup, shutdown or operation.

4-68 B4-68 explosion proof centrifugal fan Application
The 4-68 centrifugal fan can be used for indoor ventilation in general factories and large buildings. It can be used to input gas or output gas. The gas to be transported should be air not exceeding 80°C and other unnatural, harmless to humans, and non-corrosive to steel materials. The gas is not allowed to contain viscous substances, and the dust and hard particles contained are not more than 150mg/m2.
Type
Viewed from the side of the motor, the impeller rotates clockwise, which is called a right-handed fan, which is represented by "right"; when the impeller rotates counterclockwise, it is called a left-handed fan, which is represented by "left". The outlet position of the fan is expressed by the angle of the air outlet of the casing. Machine No. 2.8~6.3 All are made into one form when leaving the factory, and the user can install it to the required air outlet position according to the requirements, and there is no need to indicate when ordering; the adjustment range of the air outlet position of the machine number N08~12.5 is o°~22.5° , The interval is 45°; the air outlets of the machine numbers N016 and 20 are made of 0°, 90°, 225°, three fixed positions, which cannot be adjusted, and need to be noted when ordering.
There are four transmission modes of the fan: A, B, C, and D. No. 2.8-5 adopts A-type transmission, N06.3-12.5 adopts C and D-type transmission, and N016 and 20 adopt D-type transmission.
Structure
Type 4-68 fans with machine numbers N02.8~5 are mainly composed of impellers, casings, air inlets and other parts distributed direct-connected motors. Nc6.3~20 also have transmission parts in addition to the above parts.
(1) The impeller consists of 12 backward inclined wing-shaped blades welded between the curved wheel cover and the flat plate. They are all made of steel plate, and have undergone static and dynamic balance corrections. The air performance is good, the efficiency is high, and the operation is stable.
(2) The casing is a snail-shaped body welded by ordinary steel plates. The casing is made into two different types. The No.2.8~12.5 case is made as a whole and cannot be disassembled. The No16 and No. 20 casings are made into two-open type, divided into two halves along the horizontal plane of the middle division, and connected by bolts.
(3) The air inlet is made into a convergent line-shaped overall structure, which is installed on the side of the fan, and the cross-section parallel to the axial direction is a curved shape, which can make the gas enter the impeller smoothly, and the loss is small.
(4) The transmission part is composed of main shaft, bearing box, wave bearing, belt wheel or coupling.
Utilization of fan
Operation is permitted only when the fan is in perfectly normal condition.
It is required to check each part of the fan for normality in case of startup of the fan upon maintenance.
The fan shall be cleaned regularly and the dust, dirt and other impurities inside conveying pipeline shall be removed at regular interval to prevent rust.
It is not allowable to repair the fan when it is in operation.
A throttling device may be used for adjustment in case of excessive flow which not in compliance with operating requirements or smaller flow required in a short time.
The fan shall be immediately stopped for inspection in case of abnormality during its startup, shutdown or operation.
