A fiberglass axial flow fan

Abstract

The invention belongs to the technical field of axial flow fans, and in particular relates to a fiberglass axial flow fan, which includes a protective cover for an air outlet, a fan impeller, a lower casing of the fan, and a rotating motor. A base is arranged above the lower casing of the fan, and the rotating One side of the motor is provided with a rotating shaft, and the side of the rotating shaft away from the rotating motor is provided with an air outlet protective cover, and the upper end of the rotating shaft is provided with a fan impeller. People mistakenly touch the impeller of the running fan and cause hinge injuries. The rotary knob set on the air outlet protective cover can control the rotation of the arc groove by connecting with the rotating shaft to further control the wind direction and improve work efficiency. The sound-absorbing cotton set in the upper and lower casings of the fan can The noise generated by the fan is isolated when it is working, and the fan blade is set as a hollow cavity filled with polyurethane foam interlayered with glass fiber reinforced plastics, which can prevent the deformation of the surface of the blade after long-term work and cause equipment failure and damage.

Description

Technical field [0001] The present invention belongs to the technical field of axial flow fan, and more particularly to a glass steel axis flow fan. Background technique [0002] The axial flow fan is very wide, which is a gas stream in the same direction with the shaft of the blade, such as a fan, air-conditioned outer fountain is an axial flow fan. The reason is called "axial flow" because the gas is parallel to the fan axis. Axflow fan is usually used in cases where the flow requirements are high and the pressure requirement. Axial flow fan fixed position and moves air. The axial flow fan is mainly composed of fan impeller and housing, and the structure is simple but the data requirements are very high, and the ordinary axial fan can be used in the ventilation of general plants, warehouses, offices, and residential places. [0003] The traditional axial fan exit is open open open open open open state, and the fan does not have a protective device when the fan is working. It is...

AI Technical Summary

Problems solved by technology

[0003] The air outlet of the traditional axial flow fan is open and open to the air. When the fan is working, there is no protective device at the air outlet, which may cause people to accidentally touch the fan blades that are running at high intensity. There is no noise isolation device for the entire fan. The sound generated at the time will cause noise pollution, and the airfoil of the blade surface of the ordinary fan blade is easy to deform after a long time of work, which will reduce the working efficiency of the fan and even cause damage to the equipment and cause danger; as the use time increases, mosquitoes are easy to enter the interior It sticks inside, causing the mosquitoes inside to remain, and when it is used again, the mosquitoes inside will be flushed out, causing the mosquitoes to fly randomly, thus affecting the user experience
