Embodiment Construction

[0009] As shown in the figure, a fan blade 2 is installed at one end of the motor protection sleeve 4 in the axial flow fan housing 1, and an air inlet 3 is provided on the wall of the motor protection sleeve, and the air inlet is communicated with the flow adding device 5.

[0010] The flow adding device is a high-pressure air pump.

[0011] working principle:

[0012] Because the axial fan motor is arranged in the protective sleeve, the axial fan is isolated from the environment, thereby protecting the motor, and an air inlet is provided on the axial fan housing, which can separate the high temperature air in the axial fan with fresh air. Heat exchange, so as to prevent the axial flow fan motor from being damaged by high temperature. Therefore, the frequency conversion fan is used to cool the axial flow fan motor, which extends the service life of the motor, improves the high temperature resistance and reduces the use cost.

Abstract

The invention provides a device for improving the service life and performance of an axial flow fan motor in high temperature condition. Fan blades are installed on one end of a motor protecting sleeve in an axial flow fan shell, an air inlet is formed in the motor protecting sleeve wall, and the air inlet is communicated with flow adding equipment. The device for improving the service life and performance of the axial flow fan motor in high temperature condition adopts the sleeve and the air inlet to protect the axial flow fan motor, therefore, the high temperature resisting performance of an axial flow fan can be improved, the axial flow fan motor can be protected from being harmed by a high temperature, the service life of the axial flow fan motor is prolonged, and the device is applicable to being used as a motor protecting device for the axial flow fan.

Description

Technical field [0001] The invention proposes a device for improving the life and performance of an axial fan motor in a high temperature environment in the motor field. Background technique [0002] At present, when the axial flow fan in our country is used in a high temperature environment, it is easy to cause the motor to burn out and be scrapped because the ambient temperature exceeds 300 ℃. Summary of the invention [0003] In order to improve the service life and performance of the axial flow fan motor under high temperature conditions, the present invention proposes a device for improving the service life and performance of the axial flow fan motor under a high temperature environment. The device protects the axial fan motor through the sleeve, the air inlet and the frequency conversion motor, and improves the technical problems of the service life and performance of the axial fan motor under high temperature conditions. [0004] The solution adopted by the present inventio...
