Abstract

The invention relates to an efficient special type centrifugal fan. The efficient special type centrifugal fan comprises a spiral casing, a bearing box, a coupling, a motor and a base. An air-inlet ring is arranged at one side of the spiral casing, and a support frame is arranged at the other side of the spiral casing. The air-inlet ring comprises an air inlet and multiple connecting plates. A fluid outlet is formed in the spiral casing. A motor rod is arranged on the motor. The spiral casing is internally provided with an impeller. The top of the bearing box is provided with a fixing hole, an oil filling hole and a shaft pin. One side of the coupling is connected with the motor rod, and the other side of the coupling is connected with a rotating shaft. A baffle is arranged between the rotating shaft and the spiral casing. A deep groove ball bearing is arranged between the rotating shaft and each end of the bearing box. The two ends of the bearing box are each provided with an end cover. Each end cover comprises a connecting disc and an end enclosure. Each connecting disc is provided with a protruding ring. Each end enclosure is provided with an oil leakage hole and a fastening plate. By means of the efficient special type centrifugal fan, the technical requirements of the working condition can be met; the problem that a high-pressure centrifugal fan is low in efficiency is solved; and energy is saved.

Description

technical field [0001] The invention relates to a high-efficiency special centrifugal fan, which belongs to the technical field of high-performance fluid conveying machinery. Background technique [0002] With the advancement of my country's industrialization process, the industrial sector is vigorously carrying out energy conservation and consumption reduction, industrial upgrading and integration and reorganization, and industrial infrastructure equipment needs a large number of updates. Centrifugal fan is a driven fluid machine, relying on the input mechanical energy to increase the gas pressure and discharge the gas. As an important supporting equipment in industry, it will be more used in electric power, cement, petrochemical, coal, mining and environmental protection, etc. In the new economic development situation, the centrifugal fan industry will continue to maintain rapid growth in the future. [0003] At present, the high-pressure centrifugal fan is mainly used fo...
