煙臺拖拉機用水注意事項

人氣:83 發表時間:2023-03-22

冬季天氣寒冷,拖拉機工作條件惡化,如果使用冷卻水不當,容易使機體受到損害,因此煙臺拖拉機廠家告訴大家拖拉機冬季用水應注意以下事項。  

1、放水時要注意觀察水的情況。拖拉機長期使用,水垢雜質等容易存在于放水開關里,造成開關阻塞,使冷卻水放不盡,從而使發動機凍裂,因而機手要仔細觀察放水情況,若水流不暢,應疏通放水開關,使機體內的冷卻水全部放出。  

2、放水后要搖轉曲軸數圈,將水排凈。大中型拖拉機打開放水開關放水時,常常不能將水箱里的冷卻水放盡,一部分冷卻水還殘存在水道里,仍有凍壞機體的可能。因此,冬季放完水箱里的冷卻水后應搖轉曲軸數圈,以便將水道里的水放盡。  

3、作業結束后不要急于放水。冬季氣溫低,室外溫度一般在0度左右,如果熄火后就放冷卻水,此時由于機體溫度高達90度左右,與外界溫差大,冷卻速度快,容易造成水箱、發動機件、汽缸蓋等開裂,這時,應使發動機怠速運轉5-6分鐘,待機體溫度降致50-60度后再放水。 

4、不要先打著火再加水。拖拉機啟動后,發動機溫度急劇上升,燃燒室溫度瞬時可達1000多度。因此,若向水箱內驟然加冷水,容易使機體、汽缸套、缸蓋及渦流室鑲塊因驟冷而產生裂紋,活塞、連桿等也會變形。正確的方法是在啟動前向水箱內加注80度熱水。  以上是煙臺拖拉機廠家講解的小知識,歡迎大家多多關注我們的網站!
