油冷卻器的特色(分類介紹)：水冷式冷卻器選用水作為介質和油進行熱交換，長處是冷卻效果比較好，能夠滿足油溫比較低的要求(將油溫能夠降到40℃左zuo右you，缺que陷xian是shi必bi須xu要yao在zai有you水shui源yuan的de當dang地di才cai幹gan運yun用yong。風feng冷leng式shi冷leng卻que器qi選xuan用yong空kong氣qi作zuo為wei介jie質zhi和he油you進jin行xing熱re交jiao換huan

油冷卻器長時間不運用時，運用前應對設備進行水壓試驗，對冷熱兩邊分別試壓，試驗壓力為工作壓力的1.25倍，保壓時刻為30分fen鍾zhong
