Embodiment Construction

[0019] The present invention will be further described in detail below with reference to the accompanying drawings and examples.

[0020] Such as figure 1 A multifunctional fan performance test device shown in , includes a measuring port 3, a front air cylinder 6, and a rear air cylinder 7; the measurement port 3, the front air cylinder 6, and the rear air cylinder 7 are connected in sequence. The measuring port 3 and the front air cylinder 6 are connected through an interference fit between parts, and the other side of the measuring port 3 is also connected with the test piece through an interference fit. The performance test of fans of different sizes can be realized by replacing different measuring ports 3 .

[0021] figure 2 The middle front air cylinder 6 and the rear air cylinder 7 are positioned circumferentially through the L-shaped interface, and are positioned axially through the four bolts at the flange, which ensures a certain sealing performance and ensures tha...

Abstract

The invention relates to the technical field of fan performance testing, and provides a performance test device for multifunctional fans. The device is mainly composed of a measuring port, a front aircylinder, a rear air cylinder, a support frame and rubber plugs. The measuring port, the front air cylinder and the rear air cylinder are sequentially connected and supported by the support frame. The rubber plugs are arranged in corresponding holes of the front and rear air cylinders. The device adopts a detachable measuring port which can realize testing analysis of many different sizes of fans. The air cylinders are divided into two parts, the front and the rear. An L-shaped structure is adopted at the joint to realize circumferential positioning, and a flange is adopted to realize axial positioning. Other components can be added between the front and rear air cylinders, so the device has high configurability. Measuring holes of different sizes are formed on the front and rear air cylinders for testing the performance of a fan such as flow, noise and gas flow traces. The air cylinder is made of transparent organic glass, and colored smoke is blown into the hole of the front cylinder, so that the gas flow trace therein can be observed. The device has the characteristics of low cost, wide application, high configurability and comprehensiveness.

Description

technical field [0001] The invention belongs to the technical field of fluid mechanics test, and in particular relates to a multifunctional fan performance test device. Background technique [0002] At present, the flow test of fans generally uses thrust equivalent method, similar equivalent method and wind tunnel test method. The thrust equivalent method is generally used to test the thrust at the outlet of the fan and convert it into flow velocity equivalently, but this method will increase the wind resistance, which will change the working condition of the original fan motor, thus affecting the flow measurement. The similar equivalent method is to place a standard fan at the outlet of the fan, and measure the speed of the standard fan to convert it into the flow rate of the fan. Since the standard fan has a certain size, the gas flow rate around the fan may not be uniform, so it will affect the measurement. accuracy. The wind tunnel test method is to make the flow field...
