Ordinary bending machines are ineffective. If our operators have just taken over a new machine, they must adapt to the equipment. If the slider returns normally, the fast forward is normal, and the manual cannot be slow down. The ordinary bending machine is bent. The board is weak. Check whether the "two-position four-way" reversing valve of the control filling control oil circuit is working properly. If it is, the filling valve is not closed, so that the upper cavity is connected to the filling port of the fuel tank, and pressure cannot be built. The reason that the valve cannot work normally is that it is not powered on or is stuck. Check if the filling valve is stuck, please clean the filling valve and reinstall it to make the valve core flexible and free. The return speed of the slider is too slow, and the return pressure is high. The slider rotates quickly and slowly, and the time pauses too long. Check whether the oil level of the fuel tank is too low, the filling port is not flooded, and the upper cavity of the cylinder is filled with liquid during fast forwarding, causing insufficient filling. For the above reasons, add the oil from the oil tank of the ordinary bending machine to more than 5mm above the filling port so that the filling hole is completely flooded.
Check whether the fast forward speed is too fast, causing insufficient filling. For the above reasons, the fast forward speed can be reduced by modifying the system parameters. Wuxi Shenchong reminds to check whether the filling valve is fully opened. If it is because of oil contamination, the spool of the filling valve is not flexible and jammed, causing insufficient filling. Need to clean the filling valve and reinstall it to make the spool flexible. Whether the solenoid coil of the proportional relief valve is energized and whether the voltage of the proportional solenoid coil meets the requirements. For the above reasons, please check the related electrical reasons. Check whether the cartridge valve of the ordinary bending machine is stuck or the main valve core is stuck, and the damping orifice is blocked. If it is because of the above reasons, please disassemble the overflow valve, clean it, and reinstall it. The phase modulation of the three-phase power supply causes the motor to reverse.
