Detailed Product Description: | Mainly allocated by the centrifugal fan impeller, housing, air inlet and other units directly connected motors and components. 1) impeller by 10 sheet backward arc type blade, curved front plate and the plate after plate components. Both with steel manufacturing, and by the dynamic and static balance correction, air good performance, high efficiency, smooth operation. 2) housing made of two different types. One kind of cabinet as a whole, can not be disassembled. An enclosure made of three open into style, in addition to carve along the horizontal split in two and a half, the upper half is further divided into two halves along the vertical centerline, bolted. 3) inlet made whole, mounted on the fan side, parallel to the axial cross-section shape of the curve, the gas can smoothly enter the impeller, and minor damage. 4) transmission parts from the spindle, bearing housing, bearing, pulley components. Fans structure. Generally consists of a centrifugal fan inlet, formed a working wheel (impeller), spiral casing and the leader and other parts. Centrifugal fan configuration. The rotor member is doing work on the air, by the hyperbolic-type front plate, a plate-shaped rear plate and sandwiched between the hub and the blades fixed to the hub of the composition. Merry between flow along the blade runner, the runner exit relative velocity airflow direction W2 opposite direction with the circumferential velocity u2 called blade exit angle corner structure to β2 expressed. According to the angular size of the export structure β2, the centrifugal fan can be divided, Radial (β2 = 90o) and after tilting (β2 <90o) three kinds, β2 forward different type (β2> 90o), ventilator performance is also different. Mine centrifugal fan, mostly after tilting. There are single suction inlet and double suction two kinds. Under the same conditions, double suction blower leaf (dynamic) wheel width is twice that of single suction fan. Flow between the inlet and the leaf (dynamic) wheel is equipped with a leading (some fans leaderless device), so enter the leaf (moving) the occurrence of pre-winding wheel, to achieve the purpose of adjusting the performance. Works. When the motor drives the impeller to rotate through the gears, the air flow path between the blades rotate with the blades rotate, get centrifugal force. After the impeller blade tip was thrown into the enclosure. Velocity decreases within the housing, pressure increases, and then is discharged through the diffuser. At the same time, the leaf entry (root) to a lower pressure (lower than the inlet pressure), then flows into the inlet of the air flow under this pressure will be in effect leaves road, from root inflows in the leaf end outflow, thus a steady stream, to form a continuous flow. Mechanical ventilator is to rely on the input energy, improve the gas pressure the gas side of the mechanical transmission, which is a slave fluid machine. Exhaust pressure is lower than 1.5 × 10 Pa, fan and turbine compressor works basically the same, according to the direction of gas flow, fans can be divided into centrifugal, axial, mixed flow and cross-flow and other types. Fan widely used in various industrial sectors, generally speaking, centrifugal fan for small flow, high pressure place, while axial fan is commonly used in high-volume, low-pressure. A boiler with a fan boiler fan can be used according to the specifications of the boiler centrifugal or axial flow. But according to its role into the boiler fan - conveying air to the boiler; Boiler Fan - put away the smoke in the boiler. Second, this type of fan ventilation fan is generally used for a variety of plants and buildings ventilation and heating ventilation, the required pressure is not high, but lower noise requirements, can be centrifugal or axial fan . Third, industrial furnaces (cupola, blacksmith furnaces, metallurgical furnaces, etc.) with a ventilator fan such higher pressure, typically 2940 ~ 14700N / m2, namely the scope of the high-pressure centrifugal fan. Due to high pressure, large circumferential speed of the impeller, so the design of the impeller have sufficient strength. Fourth, the mine ventilator which there are two: one is the main fan (also known as the main fan), used to transport fresh air into the mine, the larger the flow, the use of more appropriate axial flow, centrifugal type is also useful; Another is the local fan (also known as local fan) for mine ventilation face, its flow, pressure were small, the use of explosion-proof axial fan. Five, coal fan heat boiler combustion of pulverized coal conveying system, the use of centrifugal fan. Fans can be divided according to the different uses of pulverized coal in two ways: one is the type of pulverized coal silo fan, it is by the side of the pulverized coal silo blown inside the furnace, coal is not directly through the fan, fan request The exhaust pressure is high; the other is a direct blow pulverized coal fan, it sent directly to the pulverized coal furnace. Because of pulverized coal impeller and body shell badly worn, it should be wear-resistant material.
