1) 该风室为多喷嘴风室,测量范围是 500 ~ 14000m 3 /h 。 (2) 试验对象主要以轿车冷却风扇、换热器和风扇换热器的匹配的空气动力阻力试验为主,同时可以满足部分工业风扇和换热器的测量。 (3) 风室尺寸大小是 800× 1000mm × 800mm 。 (4) 辅助风机配有风机箱,方便了进出气试验的转换,降低了噪声。 (5) 5 个喷嘴中间实行常闭或常开,调节*小和*大流量,其他 4 个大喷嘴通过电脑对联有喷嘴盖的气缸气动执行控制,实现了自动化。 (6) 整个测试与控制程序在 Labview 平台下开发。
(1) the air chamber is a multi - nozzle air chamber, and the measurement range is 500 - 14000m 3 /h. (2) the test object is mainly based on the matching of the cooling fan, heat exchanger and the fan heat exchanger, and can meet the measurement of the industrial fan and heat exchanger. (3) the size of the wind chamber is 800 x 1000mm x 800mm. (4) the auxiliary fan is equipped with a wind turbine, which facilitates the conversion of the air inlet and air test, and reduces the noise. (5) the 5 nozzles are often closed or normally open, adjust the minimum and maximum flow rate, the other 4 large nozzles through the computer to control the pneumatic actuator of the cylinder head, realize the automation. (6) the entire test and control program is developed under the Labview platform.
