Grind the dust removal fan in the form of a machine

Dust collectorfan in the form of (1) machine polishing cleaning machine made single suction fan and induced draft fan, the number of 8 ~ M28 each number 12. (2) each of the fan rotate or right and can be made into the left two forms, from the motor end face, the impeller rotating clockwise, called rotating fan, right to right & throughout; Said. Such as impeller press counter-clockwise, known as the left rotating fan, with left & throughout; Said. (3) grinding fan outlet location, expressed as a casing outlet Angle. (4) grinding is D type, fan drive motor and fan connection adopts flexible coupling transmission. (5) the product full name, for example, is as follows: the G4 - 73 - 11 18 m % d right 90 & deg; 、Y4 - 73 - 1118 d left 0 & deg; , among them, G and Y respectively steel furnace fan and induced draft fan for boiler, the highest efficiency point pressure coefficient of 0. After 437, 10 times the whole 4; Than the revolution of 73; 11 single section design for the first time; M18 said impeller diameter is 1800 mm. Dust collectormachine structure characteristics of main components of polishing cleaning machine is mainly composed of fan impeller, casing 売, air inlet, damper and transmission set ( 1) By 12 piece backward of oblique cutting the wing of the impeller blade welding in arc conical front coil and plate after the middle of flat shape. The adoption of the wing shape blade, to ensure the fan, high efficiency, low noise, high strength; At the same time, the impeller again through the dynamic and static balance correction, so running smooth. ( 2) Casing machine 売 is worm form with ordinary steel plate welded together. Single suction fan of light made 3 different form V8 ~ 売 M12 machine to make the overall structure, can't open up and down; N14 ~ N16 machine made two open 売; N18 ~ No28 made three open chassis. For induced draft fan, the volute plate made more appropriate in case of grinding. ( 3) Into the wind ロ ShouLianShi streamline of the air inlet into the overall structure, bolted in the fan inlet side. ( 4) Damper is used to adjust the fan flow device, axial installed in front of the inlet, is composed of 11 petal shaped blade, the adjusting range is from 90 & deg; ( Full close) & 0 deg. ( Full open) 。 Adjust the door pull put the position, from the air inlet direction, turn the fan on the right side, to the right, pull push from down to up is from full closed to fully open direction; The left rotating fan, pull the by, are down by a full close to full open direction. ( 5) Drive transmission group of main shaft by the high quality steel, this fan adopts rolling bearing. Bearing box has two forms: the N8 ~ M16 with whole cylinder bearing box; N18 ~ Nb28 with two independent pillow bearing box, thermometer mounted on the bearing box and oil level indicator. Machine oil, lubricating oil use 30 add oil amount according to the requirement of the oil level mark. Induced draft fan equipped with water cooling device, therefore, need to install water pipe, water consumption and varies with temperature, press zero. 5 ~ 1 m3 / h.
