Problems solved by technology

[0003] After the axial flow fan is used, various failures will occur, including the high temperature of the air inlet and the high temperature of the motor, which will have a great impact on the service life of the axial flow fan. The method of heating and heating at the air inlet cannot effectively solve the problem even after detecting the specific cause of the heating. The detection device that only detects but cannot deal with it is not very practical.

Abstract

The invention discloses a fault detection device for an axial flow fan. The fault detection device comprises a shell, a driving motor arranged in the shell and fan blades arranged on an output shaft of the driving motor. A first connecting rod is arranged on the inner wall of the shell, a mounting plate is arranged on the first connecting rod, the driving motor is arranged on the mounting plate, asleeve matched with the driving motor is arranged on the mounting plate, a first cavity is formed in the sleeve, a second cavity is formed in the shell, a second connecting rod is arranged on the side wall of the sleeve, one end of the second connecting rod is fixedly connected to the inner wall of the shell, a first through cavity communicating the first and second cavities is formed in the second connecting rod, and a temperature sensor is arranged in the first cavity; the first and second cavities are filled with clean water. When the driving motor drives the fan blades to rotate, a waterflow in the second cavity enters into the first cavity.

Description

technical field [0001] The invention belongs to the technical field of axial flow fans, in particular to a fault detection device for axial flow fans. Background technique [0002] Axial flow fans have a wide range of uses, that is, the airflow in the same direction as the axis of the fan blades, such as electric fans and air conditioner external fans are axial flow fans. It is called "axial flow" because the gas flows parallel to the shaft of the fan. Axial flow fans are usually used in occasions with high flow requirements and low pressure requirements. Axial fans hold the position and move the air. The axial flow fan is mainly composed of the fan impeller and the casing. The structure is simple but the data requirements are very high. [0003] After the axial flow fan is used, various failures will occur, including the high temperature of the air inlet and the high temperature of the motor, which will have a great impact on the service life of the axial flow fan. The ...
