Abstract

The invention relates to the field of draught fan testing and aims to provide a portable draught fan testing device and method. The portable draught fan testing device comprises a draught fan and further comprises an air inflow vortex breaking device, a measuring device and an airflow rectifying device, wherein the rear end of the measuring device is detachably connected with an air inlet of the draught fan; and the airflow rectifying device is connected with the rear end of the air inflow vortex breaking device and the front end of the measuring device. The air inflow vortex breaking device comprises a vortex breaking pipe of which the front end is larger than the rear end, a conical vortex breaking head of which the small end is located on the front side and a plurality of fixed rods which are arranged in a crossed mode and connected with the rear end of the conical vortex breaking head; the conical vortex breaking head is located in the vortex breaking pipe; and the two ends of each fixed rod are connected with the inner side of the vortex breaking pipe. The portable draught fan testing device is high in draught fan testing efficiency and precision.

Description

technical field [0001] The invention relates to the field of fan testing, in particular to a portable fan testing device and a testing method. Background technique [0002] Fans are widely used. According to the needs of use, it is often necessary to design fans with unique sizes and performances; when designing new fans, it is necessary to conduct multiple performance tests on the test bench to optimize the design; performing fan performance tests on the test bench has fan test efficiency. Therefore, it is an urgent problem to design a portable fan testing device and testing method with high testing efficiency and high testing accuracy. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies of low fan test efficiency and low test accuracy due to the influence of the intake vortex in the current fan performance test on the test bench, and provide a portable fan with high test efficiency and high test accuracy. Fan testing d...
