对连续生产的压铸机,油温过高历来是一个头痛的问题。我厂使用的J1113A 压铸机,夏天一般工作二小时以上,油温就达45℃,经常还超过50℃。油温过高,使油的粘度降低,泵内泄漏增加,建压时间延长,不得不停止生产,待油温降低后再生产。而另一台同是上海压铸机厂制造的J1513S 立式压铸机,虽然24小时连续生产,但油温一般不超过45℃。其故障少,生产效率高。两台机床的明显差别,引起我们的重视,并进
For continuous production of die-casting machine, the oil temperature is always a headache problem. J1113A die-casting machine used by our factory usually works more than two hours in summer, the oil temperature reaches 45 ℃, often more than 50 ℃. The oil temperature is too high, so that the viscosity of the oil to reduce the pump to increase leakage, build pressure time, had to stop production until the oil temperature to reduce production. The other is the same as Shanghai Die Casting Factory J1513S vertical die-casting machine, although the 24-hour continuous production, but the oil temperature is generally not more than 45 ℃. Its less failure, high production efficiency. The obvious difference between the two machine tools, causing our attention, go hand in hand
