The injection molding machine doesn't have pressure, what's wrong with it and the pressure gauge doesn't reflect it?
Pump running properly, the system pressure is not, then focus on the pressure valve
1 check the tank level first. Is it normal?2 then check to see if the oil pump motor has started yet3 check the outlet of the oil pump to see if there is any oil flowing outCan be judged to be missing oil motor failure or oil pump failure
Power supply, motor starting and turning to the right, well connected with the oil pump motor, pump in turn, hydraulic oil, proportional valve plug loose, electric proportional valve, proportional valve card is not card, proportional valve and oil outlet plug without blocking, so a sequence
