injection molding processing 时 machine causes and troubleshooting methods :
油泵噪声振动:
　　毛病 generate 缘由:
　　1, electrical machine plant/unit different 心.
　　2, device 松动.
　　3, internal 毛病.
　　4, low, from 滤油网 or 接头衔接处吸入空 gas to liquid inner.
　　5, from electrical machine make 动轴处吸入空 gas.
　　6, 油污梗塞滤油网.
　　7, tube/pipe 松动吸入空 gas or tube/pipe in upper, mixed gas to liquid in.
　　扫 remove method:
　　1, degree 应调至0.1MM以 inner.
　　2, positive device.
　　3, or 改换油泵.
　　4, increase amount in 滤油纲 and 接头位置400mm above.
　　5, 改换转动轴密封圈.
　　6, 清洗滤油网, liquid.
　　7, 清洗滤油网, liquid.
　　8, 锁紧回油 tube/pipe 路, will tube/pipe add long to 油面之 lower.
electrical machine 噪音:
　　毛病 generate 缘由:
　　1, electrical machine bearings loss bad.
　　2, electrical machine 线圈绕组毛病.
　　3, electrical machine 接线错误, system pressure upper rise 时, increase large.
　　扫 remove method:
　　1, 改换衔接 bearings.
　　2, or electrical machine.
　　3, heavy new 参照接线图接线.
　　总 pressure 阀噪音（溢流阀）
　　1, 溢流阀 先导阀 front inner has gas.
　　2, 溢流阀主阀心 upper retardant by material 梗塞. 3, 先导阀 and base/seat combined 拉伤不密 combined.
　　4, elastic deformation or 装错.
　　5, 遥控口油流 amount large.
　　6, liquid pressure viscous low or high.
　　7, and in parts generate 共振.
　　扫 remove method:
　　1, reinforcement 密封, 反? rise drop debugging pressure 几次排 gas.
　　2, 清洗阀体, make retardant 尼孔通畅.
　　3, or 改换.
　　4, and elastic 簧.
　　5, decrease/reduce 遥控口流理.
　　6, 改换油 liquid.
　　7, its it parts pressure setting can and 溢流阀 pressure setting value versus 近.
liquid pressure 油缸噪音:
　　(1)油 liquid in mixed has gas or liquid pressure in gas 未完整排尽, in high pressure function lower generate gas phenomenon 而引发 relatively large 噪声. 此时, must and 时排尽空 gas.
　　(2)缸头油封 紧 or active bending, in process in 也会因别劲而 generate 噪声. 此时, must and 时改换油封 or active 塞杆.
　　五. tube/pipe 路噪声. tube/pipe 路噪音 usually is due to liquid pressure tube/pipe 路死弯 more or solid sleeve/set 松脱 形 formed. 因而, in liquid pressure tube/pipe 路部线 upper need amount anti 止死弯, and 时检查卡 sleeve/set 松紧.
