射出機之故障與排除 Failure and Resolution of Injection Molding Machine Issues

射出機發生之故障,大部分可先由操作者自行初步處理,只要能正確的判斷故障原因、故障部位及處理方法,維修上就不會發生太大的困難。射出機大致可分為3個大體:機體、油壓、電器3個方面。如能正確判斷出電器或油壓故障之情形,那麼維修就能快且有效。
今天就先跟大家從電機馬達及油壓泵浦的問題開始。
The problems found in injection molding machines, can most of the time be solved by the operator. It is easy to repair the machine if you know how to find out the problems and solve them. Injection molding machines can be divided into 3 areas: Mechanism, Hydraulics and Electrics.
We start from motor and hydraulic pump issues.

【馬達或泵浦不回轉 Motor or Pump not Running】
  • 可能電源保險司燒斷
    Blown power fuse.
  • 可能按鈕開關接點不良
    Electrical wire contact issues
  • 過荷斷電器跳開
    Breaker jumping because of overload
【馬達或泵浦不回轉且發出嗡嗡聲 Motor or Pump not Running with buzzing】
  • 三相三線其中一相斷線或接點不通造成缺相
    Broken connection within one of the three phases
【操作中突然間停止並不再啟動 Sudden stoppage of machinery and unable to start back up】
  • 超過負荷繼電器因為過荷跳開
    Relay jumping because overload
【油壓泵浦發出異常聲響 Hydraulic pump has abnormal sound】
  • 從吸入側吸入空氣
    Air in the inhalation side of the pump
  • 濾油器阻塞
    Oil filter blockage
  • 泵浦內部軸心裂開磨損
    Inside shaft of the pump is cracked or worn
  • 油箱內油品不足或低於濾油網上緣端
    The oil in the tank is insufficient or lower than the edge of the oil filter
