Abstract

The invention discloses an efficient energy-saving draught fan convenient to overhaul. The efficient energy-saving draught fan is composed of a supporting assembly, a transmission mechanism, an impeller, a machine shell and an air inlet ring, the supporting assembly comprises an installation base, machine bases are arranged on the two sides of the installation base correspondingly, and three installation holes are formed in the front face of each machine base. The transmission mechanism is in threaded connection to the upper surface of the installation base through first screws, the machine shell is in threaded connection to the front faces of the machine bases through second screws, the outer diameter of the second screws is matched with the inner diameter of installation holes, and the impeller is arranged in the machine shell. During use, an arranged motor is started to drive the impeller connected through a connecting shaft to rotate, gas entering the machine shell through the air inlet ring is compressed through rotation of the impeller, then the gas is conveyed outwards from a rectangular air outlet, the impeller is a backward impeller, the current of the motor can be stable, the performance is more stable, and the whole draught fan is small in size. A bearing box is not arranged, and maintenance and overhaul are convenient and easy.

Description

technical field [0001] The invention relates to the field of a high-efficiency energy-saving fan with convenient maintenance, and more specifically relates to a high-efficiency energy-saving fan with convenient maintenance. Background technique [0002] Fan is the customary abbreviation for gas compression and gas conveying machinery. Generally speaking, fans include ventilators, blowers, and wind generators. The fan is a machine that relies on the input mechanical energy to increase the gas pressure and discharge the gas. It is a driven fluid machine. Fans are widely used in ventilation, dust removal and cooling of factories, mines, tunnels, cooling towers, vehicles, ships and buildings, ventilation and induction of boilers and industrial furnaces; cooling and ventilation in air conditioning equipment and household appliances ; Grain drying and selection, wind tunnel wind source and inflation and propulsion of hovercraft, etc. With the development of production technology...
