Automatic test system of axial flow fans

Abstract

The invention discloses an automatic test system of axial flow fans. The automatic test system comprises a control display module, a driving motor module, a data acquiring module, a wind tunnel module, a calibration module and a mobile module. The control display module comprises a control processor, an input unit, a display and a data bus chip. The driving motor module comprises a programmable regulating power supply and a driving motor. The data acquiring module comprises a hotline probe, an axial flow fan speedometer, a data acquisition card and a pressure sensor. The mobile module comprises a mobile controller and a mobile coordinate frame. The calibration module comprises a calibrator, a control valve, a globe valve, a filter, an air compressor, a thermocouple and a pressure sensor. The wind tunnel module comprises a wind tunnel, a diversion fan, a rectifying net, a nozzle and a frequency converter. By the aid of the automatic test system, defects of a traditional conventional testing method are avoided, testing automation of the entire process is realized, measuring errors are reduced greatly, testing efficiency is improved, and reliability of measured data is improved.

Description

technical field [0001] The invention belongs to a fan performance testing system, in particular to an axial flow fan automatic testing system. Background technique [0002] Axial flow fans are widely used in the field of ventilation and heat dissipation in expensive products such as computers, servers, air conditioners, and refrigerators. At present, the efficiency of ordinary fans on the market is generally not high. In order to make the fan operate in the high-performance area, it is necessary to refer to the performance curve of the fan to select the best operating point of the fan. At present, the methods of fan performance testing in my country are mainly traditional methods, mainly using the method of manual reading of meters. These methods are not only time-consuming and laborious, but also prone to errors in the process of manual reading records, and the test accuracy is difficult to guarantee. They have disadvantages such as many participants, low test efficiency, ...
