一台上海-50拖拉机,有半年多温度一直很高,引起机车工作无力,机油压力过低,经常烧瓦。经仔细检查后,发现是风扇的叶片变形,叶片几乎成了平面,造成风量过小,散热不良而引起车温过高。用钳子把叶片稍稍扳弯,校正以后,适当增 A Shanghai -50 tractors, more than six months the temperature has been high, causing locomotives work weak, low oil pressure, often burning tile. After careful examination, it was found that the blade deformation of the fan, the blade has almost become a plane, resulting in the air volume is too small, poor heat dissipation caused by the car temperature is too high. Pliers with a little curved leaves, after correction, the appropriate increase
