1、檢查發(fā)現(xiàn)水散熱器表面清潔，水溫傳感器和水溫表靈敏準確，節(jié)溫器能夠正常啟閉，發(fā)動機運轉(zhuǎn)平穩(wěn)有力，但冷卻風(fēng)扇轉(zhuǎn)速稍慢。
Inspection found water radiator surface clean, temperature sensors, and temperature sensitive and accurate table, the thermostat can open and close properly, smooth and powerful engine is running,but the cooling fan speed slower.
2、用壓力表檢測冷卻風(fēng)扇驅(qū)動泵輸出壓力偏低，調(diào)整泵壓力調(diào)節(jié)器調(diào)整螺栓，壓力沒有變化。
The cooling fan driven by pressure gauges to detect pump output pressure is low, adjust the pump pressure regulator adjusting screw, the pressure does not change.
3、將壓力調(diào)節(jié)器拆解、清洗、檢查，未發(fā)現(xiàn)異常。對泵進行拆解、清洗、檢查，也未發(fā)現(xiàn)異常。
The pressure regulator disassembled, cleaned, inspected, and found no abnormalities. The pump dismantling, cleaning, inspection, and found no abnormalities.
4、將風(fēng)扇馬達拆解、清洗、檢查，發(fā)現(xiàn)風(fēng)扇馬達磨損嚴重，更換風(fēng)扇馬達后試機，20分鐘后發(fā)動機水溫依然正常。
The fan motor dismantling, cleaning, inspection, found that the fan motor badly worn, replace the fan motor testmachine, 20 minutes after the engine temperature remained normal.
