液压类数控折弯机故障分析
Failure analysis of hydraulic numerical control bending machine
故障一:液压系统无压力。
Fault 1: no pressure in the hydraulic system.
1、比例溢流阀的电磁线圈是否得电,比例电磁线圈电压是否符合要求,如上述原因,请检查相关电气原因。
1. Whether the solenoid coil of the proportional relief valve is electrified or not, and whether the voltage of the proportional solenoid coil meets the requirements, if the above reasons, please check the relevant electrical reasons.
2、检查插装阀是否卡死或主阀芯是否被卡死,以及阻尼小孔堵塞,如果是上述原因,请拆卸溢流阀清洗干净,重新装上。
2, check whether the cartridge valve is stuck or the main valve is stuck, and the damped hole is blocked. If it is the above reason, remove the overflow valve to clean and reinstall.
3、三相电源调相,导致电机反转。
3, phase modulation of three phase power supply leads to motor reversal.
故障二:滑块快速转慢速,时间停顿过长。
Fault two: slider quickly turn slow, time pause is too long.
1、检查油箱油面是否过低,充液口未被淹。?旖?庇透咨锨怀湟何?找?鸪湟翰蛔。如上述原因可以将油箱油液加至充液口上方5mm以上使充液孔完全被淹住。
1. Check whether the oil level of the fuel tank is too low, and the filling port is not flooded. For the above reasons, the tank oil can be added to the 5mm above the filling port to make the filling hole completely submerged.
2、检查快进速度是否太快,引起充液不足。如上述原因可通过修改系统参数降低快进速度。
2, check whether the fast forward speed is too fast, causing insufficient fluid filling. For these reasons, fast forward speed can be reduced by modifying the system parameters.
3、检查充液阀是否被完全打开,如果是因为油液污染,使充液阀的阀芯活动不灵活有卡滞现象引起充液不足。需要清洗充液阀重新装上使阀芯灵活自如。
3. Check whether the filling valve is completely opened, if it is because of oil pollution, so that the valve spool of the filling valve is not flexible, there is a stuck phenomenon caused by insufficient filling. It is necessary to clean the filling valve and reinstall it to make the valve core flexible.
故障三:滑块返程正常,快进正常,手动不能慢行向下,折板无力。
Fault three: slider return to normal, fast forward normal, manual not slow down, folded plate weak.
1、检查控制充液控制油路的“二位四通”换向阀是否工作正常,如果是则引起充液阀未关闭,使上腔与油箱充液口相通,不能建压。导致该阀不能正常工作的原因是没有通电或者被卡死。
1. Check and control the "two - position and four - way" reversing valve of the oil filling control oil way to work normally, if it is, the valve is not closed and the upper chamber is connected with the tank filling port, and the pressure can not be built. The reason why the valve does not work properly is that the valve is not energized or jammed.
2、检查充液阀是否被卡死,如是,请清洁充液阀,重新装上,至使阀芯灵活自如。
2, check whether the filling valve is stuck. If yes, please clean the filling valve and reinstall it, so that the spool is flexible.
故障四:滑块返程速度太慢,回程压力高此类故障主要是充液阀未打开,此现象刚好与上述故障三的现象逻辑关系相反,可参照故障三的解决方法进行处理。
Fault four: the return speed of the slider is too slow and the return pressure is high. The main fault is that the valve is not opened. This phenomenon is just contrary to the logic relation of the above fault three, and can be handled with reference to the solution of the fault three.
