第一：机器本身压力不足、第二：包块尺寸不合理、第三：长时间使用有漏油或者油泵部件损坏，调整溢流阀。:以下为液压打包机故障排查方法. Obviate the malfunctions
电机不能启动 1. The motor can not working
、电源电压是否正常：用仪表或探笔测试。① Check the voltage whether is normal or not: use the ammeter or testing pen.②、保险管是否容断：如保险管容断，保险管座小红灯会亮起。（图7右）② Check the fuse whether is broken or damage: if the fuse damaged, then the small red lamp of the fuse will be light (with the picture 7 right).
交流接触器是否损坏：查看触点是否损坏，接触器吸合是否正常。（图6左）The contactor whether damaged: check the touch point whether is normal or not, the contactor which suction or close whether is normal or not (with the picture 6 left).
、上下行程开关：松开外盖查看触点，重新调整。The up & down journey switch: loose the outside cover to check the touch point, and adjust again.
⑤、过载保护器是否脱开：（图6右）待冷后自动复合，检查电机是否发热。Whether the over loading protector is loosed or not: (the picture 6 right) after cool then will be restoration automatically, and check the motor whether is hot or not.
噪声增大： 2. The increased noise
、油量不足：往油箱加油。The hydraulic oil not enough: add the hydraulic oil into the oil box.
、滤清器堵塞（图2）：拆下滤清器用汽油或柴油清洗。Filtering jamming (picture 2): discharge (take away) the filtering and wash it by the gasoline or diesel oil.
③、底温环境工作：机器运行约15分钟，当油温度自行升高即可。Working temperature: after the machine run 15 minutes, when the hydraulic oil’s temperature increased then be ok.
3、压板在手动阀控制时不能上下移动：3. The compressing plate can not move up or down when control the manual valve handle:
①、电机转向是否正确：如电机转向相反请重新把电源线两相互换接上。The motor’s rotary direction whether is correct: if the motor’s rotary direction is reverse or opposite then change the electrical wires and connect again.
②、油泵是否正常工作：油泵工作时查看油箱内是否有对流现象，如无对流现象，证明油泵已损坏。The oil pump whether is working normally: check the oil box inside whether with the convective phenomenon, if without the convective phenomenon then the oil pump was damaged.
③、溢流阀（调压阀）（图4）是否堵塞：松开溢流阀各部份配件仔细清洗，因溢流阀内有工作小孔，如液压油有杂物，很容易堵塞工作小孔造成机器不工作或无压力。（附图4）注！溢流阀一般不轻易损坏只有堵塞现象较多。The flooding valve (pressure adjusting valve) (picture 4) whether jamming: loose each part of the flooding valve and check carefully, for the flooding valve inside with the working holes, if the hydraulic oil with the dirty thing or sundries, then will easily to jam the working holes and cause the machine not working or without pressure. (with picture 4) Attention! The flooding valve not easy to be damaged just the jamming phenomenon (problem) will be more.
4、正常工作无压力：4. Normally working without the pressure:
调整溢流阀。参照（调整2）Adjust the flooding valve. Reference (Adjustment 2)
清洗溢流阀。（参照图4）Washing the flooding valve. (reference the picture 4)
油泵是否损坏。The oil pump whether was damaged.
保养维护：Maintenance:
、油箱内虑网要定期清洗（图2）（6个月一次）The filtering screen of oil box need to be washed every 6 months (picture 2)
、50T机型以下带附杆的，每周在附杆表面加抹润滑油。The model less than 50T with the additional pole, need to add the lubricating oil for the surface every week.
、活动门及摇臂要定期加润滑油。The doors and the rockers need to add the lubricating oil from time to time.
、油箱顶部加油口盖有一空气呼吸孔不能被杂件堵塞。The air hole of the oil box’s top can not jam by the sundries or dirty thing.
把压力调到20MP左右即可，检测系统压力先检查溢流阀，如果更换油泵费用就太大了，那你就要更换溢流阀了1，观察一下溢流阀。先把油泵打开 ，****可以浏览该公司官方网站，打开前腔油管，可以根据情况逐个排查2，如果还不能达到压力值，如果系统压力表值在20MP左右，以免组装不上，配油盘，问题判断方法为。日产量在80T以上的打包机会采用高压叶片泵。3，换向阀用O型阀或Y型阀你好，再用第一部分方法检测系统压力，叫阀芯，那你就要检修油泵了，你要顺时针旋转溢流阀压力调节手轮，也就是油缸了，推不动纸，一般有一下三点原因造成的，现在很多厂家都采用电磁溢流阀洗（以下简称溢流阀），你最好在厂家指导下更换，溢流阀线圈末端园面中心有一个直径6mm左右的金属芯。如果压力表值10MP左右，最经济的维修办法是更换柱塞，那你就要更换整个油泵了。
