新能源汽車電機(jī)冷卻系統(tǒng)壓力檢測(cè)
New Energy Vehicle Motor cooling system Pressure Detection
新能源汽車是目前全球汽車產(chǎn)業(yè)發(fā)展的一個(gè)大趨勢(shì)，其中電動(dòng)汽車為一個(gè)主要分支。電動(dòng)機(jī)作為
電動(dòng)汽車驅(qū)動(dòng)可實(shí)現(xiàn)極低排放或零排放。電動(dòng)汽車在驅(qū)動(dòng)與回收能量的工作過程中，電動(dòng)機(jī)定子
鐵芯、定子繞組在運(yùn)動(dòng)過程中都會(huì)產(chǎn)生損耗，這些損耗以熱量的形式向外發(fā)散。所以系統(tǒng)需要有
效的冷卻介質(zhì)及冷卻方式來帶走熱量，保證電動(dòng)機(jī)在一個(gè)穩(wěn)定的冷熱循環(huán)平衡的通風(fēng)系統(tǒng)中**
可靠運(yùn)行。電動(dòng)機(jī)冷卻系統(tǒng)設(shè)計(jì)的好壞將直接影響電動(dòng)機(jī)的**運(yùn)行和使用壽命。
At present, new energy vehicle is a major trend in the development of the global auto industry, in which
electric vehicles is a major branch. Motor as an electric vehicle power resource can achieve very low or
zero emissions. In the process of driving and recovering energy of electric vehicle, the motor stator core
and stator winding will generate heat in the process of movement. Therefore, the system needs
effective cooling medium and cooling method to take away the heat to ensure the safe and reliable
operation of the motor in a stable cold. The design of motor cooling system will directly affect the safe
operation and service life of motor.
新能源汽車驅(qū)動(dòng)電機(jī)冷卻系統(tǒng)一般與電力電子箱（PEB：Power electrical box）共用，PEB 和驅(qū)動(dòng)
電機(jī)的工作溫度不能超過 75℃，*合適的工作溫度應(yīng)該低于 65℃。將溫度控制在 75℃以下可以
更好的延長 PEB 和驅(qū)動(dòng)電動(dòng)機(jī)的使用壽命。
The motor cooling system is generally shared with PEB Power electrical box. The operating temperature
of PEB and driving motor cannot exceed 75 ℃, and optimum working temperature should be below
65 ℃. Temperature control under than 75 ℃ can prolong the service life of PEB and drive motor.
所以廠家為了確認(rèn)冷卻系統(tǒng)的可靠性和密封性，針對(duì)冷卻系統(tǒng)耐壓與密封性做出廠測(cè)試是必要
的。系統(tǒng)耐壓測(cè)試壓力范圍 0~1.5MpaG， 需求測(cè)試精度>=0.2%FS，校準(zhǔn)溫度范圍-20~80℃。密封
測(cè)試壓力為 0.15MpaG，測(cè)試精度>=0.2%FS, 溫度范圍-20~80℃。
Therefore, the OEMs are necessary to verify cooling system reliability and sealing performance before
final assembly. The pressure range of over pressure test is 0~1.5MpaG, precision > = 0.2%FS, calibration
temperature range-20 ~ 80 ℃. Sealing test pressure range is 0~0.15MpaG, test precision > = 0. 2%FS,
temperature range-20 ~ 80 ℃.
汽車測(cè)試行業(yè)是 Druck 傳感器的傳統(tǒng)應(yīng)用行業(yè)，具有很高的市場(chǎng)占有率。針對(duì)于客戶需求，推薦
產(chǎn)品方案如下：
PTX5072-TB-A*-CA-PB，0-1.5barG/0~15barG. 具體精度可根據(jù)客戶實(shí)際需求配置。
通過與客戶相關(guān)應(yīng)用技術(shù)溝通交流，已有國際***的新能源汽車企業(yè)正常安裝使用。綜合考慮
Druck 傳感器主要優(yōu)勢(shì)有如下三點(diǎn)： Druck 產(chǎn)品高精度； 優(yōu)良的長期穩(wěn)定性；具有本地生產(chǎn)工廠
和技術(shù)支持可快速響應(yīng)客戶需求。
Auto testing industry is a traditional application segment of Druck sensor which has high market
sharing. According to customer requirements, recommended schemes are as follows:
PTX5072-TB-A2-CA-PB，0-1.5barG/0~15barG
