產(chǎn)品描述:K9203A 996920360 HIMA 散熱風扇 確認風扇軸承和IP防護等級
步:確定風扇工作電壓
一般散熱風扇電壓有:12V,24V,48V ,電壓確定之后就判斷自己所需是AC交流風扇,DC直流風扇,或是EC風扇,各類型特點和優(yōu)缺點如下:
AC風扇:特點:金屬散框
優(yōu)點:無需適配器,抗浪涌強,單價便宜。
缺點:風扇轉度范圍小,且不能調速,無RD與FG信號,有堵轉保護。
DC風扇:特點:注塑塑框
優(yōu)點:安全電壓,安裝尺寸及轉速范圍選擇性較多,轉速可調,有RD與FG信號可選,堵轉等保護。
缺點:高轉速噪音高
EC風扇:特點:AC/DC供電,注塑塑框
優(yōu)點:可做全電電壓,可做調速,可做RD/FG,轉速范圍寬,有堵保等保護。
缺點:抗浪涌弱,單價高
第二步:確認適合的風扇類型
可選風扇類型:橫流,軸流,離心機,鼓風機
橫流散熱風扇特點;風量大,風壓小
軸流風扇特點:進出風同一個方向
離心風扇特點:進出風成90度,風量大,風壓高
鼓風機特點:進出風成90度,風量小,風壓高
第三步:確認風量和風壓
參考值:動作點,靜態(tài)值,PQ曲線,轉速,噪音,電流
第四步:確定風扇基本型號參數(shù)
基本參數(shù);品牌,型號,尺寸,電壓,電流,轉速,風量,風壓,噪音
第五步:確認風扇軸承和IP防護等級
軸承類型:含油軸承,液承,滾珠軸承
軸承壽命:含油軸承:30000H/25度
液承:30000H/40度
滾珠軸承:50000H/40度
IP防護等級:IP55:防漆可以滿足,可防水濺,IP67:可防雨淋和水柱IP68:可在雨水中工作
第六步:確認功能和安裝
風扇功能選擇:FG測速功能,RD報警功能,PWM調速功能,自啟動功能
散熱風扇安裝;扇框,引線,端子,線序
扇框:通孔鎖螺絲一定要選,有連柱的扇框。
引線:引線有分線,并線,絞線,默認分線,線長默認框外到端子。
端子;常用端子型號:HX2.54,PH2.0,2510,飛機頭等。

Step 1: Determine the fan voltage
General cooling fan voltage: 12V,24V,48V, after the voltage is determined to determine their own need is AC fan, DC DC fan, or EC fan, each type of characteristics and advantages and disadvantages are as follows:
AC fan: Feature: Metal loose frame
Advantages: No adapter, strong surge resistance, cheap unit price.
Disadvantages: The fan rotation range is small, and cannot be adjusted, no RD and FG signals, and blocked rotation protection.
DC fan: Feature: Injection molding frame
Advantages: safe voltage, installation size and speed range more selective, adjustable speed, RD and FG signal optional, blocked rotation and other protection.
Disadvantages: High speed and high noise
EC Fan: Features: AC/DC power supply, injection molding frame
Advantages: Can do full electric voltage, can do speed regulation, can do RD/FG, wide speed range, plug protection.
Disadvantages: weak surge resistance, high unit price
Step 2: Determine the appropriate fan type
Optional fan types: cross flow, axial flow, centrifuge, blower
Cross-flow cooling fan features; Large air volume, small wind pressure
Axial fan features: The inlet and outlet air are in the same direction
Centrifugal fan features: inlet and outlet wind 90 degrees, large air volume, high wind pressure
Blower features: inlet and outlet wind 90 degrees, small air volume, high wind pressure
Step 3: Confirm the air volume and pressure
Reference value: action point, static value, PQ curve, speed, noise, current
Step 4: Determine the basic fan model parameters
Basic parameters; Make, model, size, voltage, current, speed, air volume, wind pressure, Noise
Step 5: Confirm the fan bearing and IP protection level
Bearing type: oil bearing, hydraulic bearing, ball bearing
Bearing life: oil bearing: 30000H/25 degrees
Hydraulic bearing: 30000H/40 degrees
Ball bearing: 50000H/40 degrees
IP protection level :IP55: anti-paint can meet, can be waterproof splash, IP67: can prevent rain and water column IP68: can work in rain
Step 6: Confirm functionality and installation
Fan function selection: FG speed measurement function, RD alarm function, PWM speed regulation function, self-start function
Cooling fan installation; Fan frame, lead, terminal, line sequence
Fan frame: through hole lock screw must be selected, there is a fan frame with a column.
Lead: The lead has branch line, parallel line, twisted line, default branch line, line length default box outside the terminal.
Terminal; Common terminal type: HX2.54, PH2.0,2510, aircraft first class.
