風(fēng)機風(fēng)量測試臺測試要求
1) 該風(fēng)室為多噴嘴風(fēng)室,測量范圍是 500 ~ 14000m 3 /h 。 (2) 試驗對象主要以轎車(chē)冷卻風(fēng)扇、換熱器和風(fēng)扇換熱器的匹配的空氣動(dòng)力阻力試驗為主,同時(shí)可以滿(mǎn)足部分工業(yè)風(fēng)扇和換熱器的測量。 (3) 風(fēng)室尺寸大小是 800× 1000mm × 800mm 。 (4) 輔助風(fēng)機配有風(fēng)機箱,方便了進(jìn)出氣試驗的轉換,降低了噪聲。 (5) 5 個(gè)噴嘴中間實(shí)行常閉或常開(kāi),調節zui小和zui大流量,其他 4 個(gè)大噴嘴通過(guò)電腦對聯(lián)有噴嘴蓋的氣缸氣動(dòng)執行控制,實(shí)現了自動(dòng)化。 (6) 整個(gè)測試與控制程序在 Labview 平臺下開(kāi)發(fā)。
(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.
