1、机器无法启动
其主要原因
1）停电或线路不通。需检查主电机动力安装线路是否有故障。
2） 如果管路中装配了自动安全控制系统, 则需检查系统是否进料或出料故障。
2、主电机反转
即主电机与规定转向不符, 只需将三相电动机中的地线换一相。
3、传动箱声响异常, 其产生的原因及排除方法
1）检查传动箱内油位是否正常, 如果油液不足需加油至油标刻度处。
2）检查传动箱内各联接部位是否有松动, 如果有松动, 应逐个拧紧。
4、造成不出料或出料不足的原因及排除方法
1）断料或进料不足, 设备在运行过程中需要要保证进料充足。
2）物料黏度过大, 如发生这种情况, 则需要用压力进料或稀释物料。
3）主电机传动皮带打滑; 需调紧皮带。
4）柱塞密封圈泄漏, 需更换密封圈, 如属柱塞磨损则需更换柱塞。
5）液流端处阀芯阀座磨损, 则需要换阀芯阀座。
6）液流端内6组阀芯阀座中有损坏现象或有杂质粘在密封线上，应检查损坏情况并及时调换，调换下来的零件可According to损坏情况进行研磨回用或报废。
5、压力表指针摆动大于正负两格
1）所有 5- 4 中的原因均会造成压力表指针摆动增大。
2）柱塞与连杆联接处松动, 需重新固定联轴器。
3）连杆与十字头联接处松动, 需要重新拧紧固定螺钉。
4）压力表表座内机油量不足, 将表座内柱塞压到底，然后加满机油。
5）均质阀损坏严重, 需更换均质阀。
6）连杆或柱塞的联轴器松动。
7) One or more sets of six sets of valve cores and valve seats in the liquid end (pump body) are stuck.
8) For valve seats with seals, the seals may be damaged.
6. There is no pressure in the pump or the reason why the pressure cannot go up and the troubleshooting method
1) There is no feed.
2) The transmission belt of the main motor is loose, and the belt needs to be tightened.
3) If the response of the current value of the main motor is normal , it may be: (a) The oil in the pressure gauge seat has leaked out, and the oil should be filled up. (b) The pressure gauge is damaged and needs to be replaced.
4) There are impurities in the sealing part of the homogenizing valve or the homogenizing valve is damaged; it is necessary to check and clean the homogenizing valve, and replace it if damaged.
5) The spool seat in the fluid end is damaged or the seat seal is invalid; the spool seat needs to be replaced or the sealing ring needs to be replaced.
7. The pressure gauge pointer does not return to zero after pressure relief
1) If the pointer of the pressure gauge still does not return to zero after shutdown, the pressure gauge is damaged and the pressure gauge needs to be replaced.
2) The sealing ring of the pressure regulating ejector rod is damaged or too tight, and it is necessary to replace the sealing ring or adjust the fit clearance.
