Summary
1, 6-46-11 type dust centrifugal fan is suitable for discharging the mixture of air, such as wood debris, fiber and dust.
2, the fan model is expressed by 6-46-11, which:
(1) 6 said fan at the highest efficiency (max) of the total pressure coefficient by 10 after the integer.
(2) 46 said fan at the highest efficiency (max) is the specific speed of integer.
(3) in which the first digit number (1) represents the single suction fan, and the number of the number of 1 represents the design sequence number () number of 11.
3, No. 4 for the following fan, in the range of working efficiency and the pressure decline in its value shall comply with the following provisions:
(1) No. 4 is not lower than the curve on the specified value 95%.
(2) No. 3 is not lower than the curve on the specified value 90%.
structure
4, No. 3-6 meters for motor direct (A type) and the pulley (C type) two transmission mode. No. 8-12 meters pulley (C type) and coupling (D type) two transmission mode.
5. The fan has 6 blades which are bent forward, the front plate and the rear plate and the cast iron wheel shell. Impeller dynamic balance test, smooth operation.
6, the spindle adopts high quality carbon steel manufacturing.
7, for the maintenance of convenient installation, no 3-12 fan casing, are integral.
8, the ventilator can be made into left and right rotary rotary two styles, fixed on the air inlet side and outlet position of each rotary direction, no 3-6 into 6 different positions, no 8-12 can be made into 3 different positions.

Installation, use and maintenance instructions
1, before installation should be checked in detail whether the fan parts are damaged, to be properly repaired before installation.
2, before installation should be checked in detail whether the connection part of the phenomenon of loosening, impeller and air inlet gap size, rotating part and fixed part whether there is a collision phenomenon.
3, the chassis and bearing bearings should be consistent with the nature of the foundation, may not be forced to avoid deformation.
4, the motor shaft and the fan shaft should be carefully corrected concentric vibration, so as not to run.
5, after the installation is completed, carefully check whether the bolts are tightened around, and try running.
6, fan flow Q and total pressure of H, spindle speed and shaft power of n N four have a fixed relationship shown as the following formula.
When the motor capacity does not change, not change the spindle speed, spindle speed increases, the motor had burned the dangerous load.
7, the fan motor refers to the specific conditions and mechanical loss and its reserves, is not required to open the air outlet power, such as the entrance or exit with pipeline or not by the external resistance of idling, the motor is in danger of being burned. The safety valve should be added to the outlet or inlet pipe of the fan, the valve will be opened slowly to achieve the specified operating conditions, and pay attention to whether the motor exceeds the specified current.
8, rolling bearing using yellow glycerine lubrication, oil should not be too much, you can in the rolling bearing center, in maintenance shall not be mixed with sand, iron inside.
9, the bearing temperature in normal operation shall not exceed 65 degrees, otherwise it should be checked and repaired.
10, pay attention to the impeller or belt wheel rotation is balanced, the connection is loose, whether the body vibration, should be checked and corrected at any time.
11, V type tape should be often uniformly strained and the ambient temperature should not be too high, and avoid contact with oily tape.
12, with the coupling drive should pay attention to the motor and spindle concentricity, in order to avoid vibration or cause bearing heating and so on.

13, the ventilator should be special maintenance, regular maintenance, repair time varies with the use of the length, the selection should be in accordance with the actual conditions.
