Boiler fan GY2-1

Short Description:

Fan Product Overview

1. The use of fans and characteristics

GY2 ~ 10-1 is 2,4,6,10 t / h industrial boiler supporting private-Fan, the current industrial boiler series models are more pros and cons of burning coal for the poor, it is equipped with a dust collector resistance economizer varies, the amount of wind-fan is required, there is a certain pressure difference, which-fan designed with the above situation. Compared with the first wife boiler fan, its distinguishing feature is its wind, air pressure and the boiler to match the requirements. High efficiency, smooth performance curve, efficient wide area, due to the high pressure, is conducive to the boiler smoke and dust, improve environmental protection, the use of a specially designed two-speed motor, its power and fan power requirements match the different speeds when, users can run the boiler load size, choose a different speed, energy saving effect is very significant, is the ideal energy saving supporting fan.

2. fan type

(1) pass, the draft fan made single suction fan can be made of two types of right-handed or left-handed, a front end from the motor fan, impeller clockwise rotation of the fan ,, called the right to “right”, said, on the contrary, He said left rotation fan to “left”.

A network port location (2) fan to fan outlet angle to the cabinet said, can be made of about 0 °, 45 ° left and right can be made, if necessary, 90 °, 135 °, 180 °, 225 ° different export direction.

(3) through the induced draft fan transmission mode for A-type and D-two.

3. To wind structure

Main-Fan impeller, housing, air inlet, frame, transmission group, adjust the door and so on.

(1) Impeller: there fan impeller blade 10 leaves or leaf 12, is bent backward or straight blade, Fan impeller has 16 blades or vanes 12, is a forward curved blades. Impeller were all made of 16Mn steel impeller molding by the dynamic balance correction, so He stable and reliable, has high strength and wear resistance, long service life.

(2) Chassis: Common-Fan are made of welded steel plate snail shell as a whole.

(3) inlet: made convergent streamline the overall structure, bolted to the chassis side or the inlet flange portion fixed to the front cover.

(4) Adjust the door:-Fan all with damper, with adjustment means fan air volume and fan damper leaf petal-shaped, since I drive structure, rotating flexible and convenient, adjustment range by a 90 ° (fully closed ) to 0 ° (full) to adjust the position of the door handle from the air inlet direction, on the right, on the right-hand rotary handle is pulled up by the fan is fully closed to fully open direction.

(5) Bracket:-Fan are made of welded steel.

(6) Transmission group: from the spindle, coupling, bearing housings and other components, the spindle is made of high quality steel. Rolling bearing, equipped with a thermometer and oil level instructions on the bearing housing, with 30 machine oil lubricating oil, fuel oil according to their sign, depending on the induced draft fan bearings cabinets containing copper coil through the water for cooling the lubricating oil after water consumption based on the actual circumstances, generally by 0.5 ~ 1m 3 / h consideration.
