Centrifugal fans with power regulator AIR FLOW ('Crown' Sukhinov VS)

摘要

Use: the pumps for controlling and power control suction and air blowing in the pneumatic lines and pneumatic different machines, in particular in agricultural aerodynamic separators intended for the preparation of seeds for sowing and for breeding purposes, and in various machines working in the food, chemical , processing and other industries, are intended for the separation of bulk materials in current air. SUMMARY: centrifugal fan airflow power regulator comprises a housing with inlet and outlet nozzles, wherein the axle is mounted on the impeller with blades associated with the drive shaft, and the air flow regulator. Inlet is designed as a crown gear with sharp teeth directed from the fan housing. Power control of the air flow is designed as a coaxial movable flap diameter and shape corresponding to the shape and diameter of the inlet pipe. The flap is movable along the inlet pipe by a manual drive or servo screw. The controller can be disposed on the outlet conduit. The flap can be moved outside the crown gear teeth. The base of the crown gear teeth can be located at different levels.; Technical advantages; range extension smooth fan productivity regulation at its minimum capacity; maximum simplification of control structures; maximizing operational reliability; Use area expansion; maintainability design. 1 is independent of n.
