Efficient energy-saving fan with wide performance range

Abstract

The invention provides an efficient energy-saving fan with a wide performance range, and belongs to the technical field of fan equipment. The efficient energy-saving fan with the wide performance range comprises a machine base, wherein a machine shell and a motor are fixedly installed on the machine base through bolts, the output end of the motor is formed in the machine shell, an adjusting device is connected to the output end of the motor, an outlet flange is fixedly installed on the machine shell through bolts, and an air inlet ring is fixedly installed on the side, far away from the motor, of the machine shell. The matched power of the motor is low, an A-type transmission structure is compact, the size is small, a bearing box is not arranged, maintenance and overhaul are convenient and simple, the current of the motor is stable, and the performance is stable; and the efficient energy-saving fan can be manufactured into a C-type, D-type or other transmission modes according to other working conditions with temperature, humidity and the like, so that electricity is saved, and the operation cost is reduced.

Description

technical field [0001] The invention belongs to the technical field of fan equipment, and in particular relates to a high-efficiency and energy-saving fan with a wide performance range. Background technique [0002] Fan is a machine that relies on input mechanical energy to increase gas pressure and discharge gas. It is a driven fluid machine. The invention with the publication number of CN205277883U discloses a high-efficiency energy-saving fan, including a fan body; the fan body is equipped with A fan casing, a fixed bracket is welded on the outside of the fan casing, an air inlet is provided inside the fan casing, a motor is installed on one side of the fan casing, and an output shaft is provided at the output end of the motor. One end of the output shaft is provided with a fan blade fixing seat, and a fan blade is installed on the fan blade fixing seat, a governor is provided on one side of the motor, a controller is provided on one side of the governor, and the fan A t...

Problems solved by technology

It is necessary to choose a fan of a larger model, such as 5-48-5.6C, with a power distribution of 15Kw and a speed of 2500rpm, which can meet the requirements of the working conditions, and the speed can be adjusted through the ratio of pulleys or frequency conversion to meet the performance requirements. Not only the power distribution of the motor is relatively large, but also it is C type. Pulley drive or frequency conversion increases the purchase cost. Compared with the A-type direct-coupled fan, it brings the disadvantages of high purchase cost, large floor space, and relatively complicated maintenance.
