Quantitative Pump Fault Analysis and Solution

(A) Quantitative pump failure analysis and solution Item Fault conditions Possible causes Remedy 1 pump does not spit oil 1. Rotate in the opposite direction Check the motor direction, correct 2. Pump shaft does not turn Check the coupling, and Key 3. Oil filter plugging cleaning oil filter 4. Oil filter deformation change 5. Oil viscosity is too high a. Oil change b. Oil heating (too cold) 6. Suction pipe leak a. Grease blocked b. Change 7. The oil-absorbing net is not sunk into the oil surface. Add the oil below the upper and lower limit of the oil-level meter. 2 The noise is very big 1. The oil filter blocks the oil filter 2. The viscosity is too high Oil change, oil heating (too cold) 3. Inhalation of air from the pump front cover Applying the butter Apply the grease at the joint to improve the leakage. 4. There is a bubble in the oil return pipe to be sunk below the oil level. 5. The oil level is insufficient Add the operating oil to the upper and lower limit of the oil level gauge. Check if the connector is damaged or damaged by noise at the pipe connector 7. Internal and external damage to the pump Replace the oil pump (2) Causes and solutions of each operation fault Item Fault condition Possible cause Solution 1 No operation at mold opening / closing 1.

Pressure or flow setting is too small Increase the pressure and flow settings 3. Proximity switch position is inappropriate or fault Adjust the seat into the end seat back cut close proximity switch position or replace 4. Solenoid valve Faulty or blocked oil circuit Change solenoid valve or purge solenoid valve 3 Injection / ejection unable to move 1. No manual state Press manual key 2. Pressure or flow setting is too small Increase pressure / flow setting 3. Solenoid fault Or blocked oil circuit to replace the solenoid valve or solenoid valve cleaning 4. Tube temperature is not expected to reach the set temperature of the material 5. Injection time or position is not appropriate to adjust the shot 1 to 4 position and injection time 6. Automatic state of the retired time or Position setting is not appropriate to adjust the back-off time or position 4 feeding does not move or stop 1. No manual state Press the manual key 2. Pressure or flow setting is too small Increase the pressure and flow settings 3. Tube temperature is not expected to be expected Temperature reached the set Degree 4. No material feeding 5. Automatic, material supervision, time adjustment is not appropriate to adjust the storage supervision time and feeding completion position 6. Solenoid valve failure or oil circuit change solenoid valve or solenoid valve cleaning 5 Mold in / out can not Action or stop 1. No manual state Press the manual key 2. Pressure or flow setting is too small Increase the pressure and flow settings 3. Solenoid valve failure or blocked oil Change the solenoid valve or solenoid valve cleaning 4. Mold not in place Mold open to the end of the mold position 5. Mold in / out of the proximity switch proximity adjustment proximity switch 6 mold thickness into / out can not move 1. No manual state press the manual key and the mode key 2. Pressure or flow Set too small Increase the pressure and flow settings 3. Solenoid valve malfunction or blocked oil Replace the solenoid valve or clean the solenoid valve 7 Neutrons in / out 1. No manual state Press the manual key 2. Pressure or flow settings Too small to increase the pressure and flow settings 3. Solenoid valve malfunction or blocked oil Change the solenoid valve or solenoid valve cleaning 4. Neutrons into the neutrons out of time, the number of improper adjustment of neutron into the neutron time, the number of 8 can not Automatic operation 1. The pressure of each action, flow ﹑ Time adjustment properly adjusted to 2. The proximity of each action switch is inappropriate Proximity switch to adjust the appropriate 3. Not put in full automatic state Press the timer automatically key 4. Solenoid valve failure or blocked oil Change the solenoid valve or clean the electromagnetic Valve 5. Front and rear safety door is not closed before and after the safety door closed 6. Cam valve does not pop up to reset the cam valve 7. Safety device circuit check circuit 9 can not be semi-automatic operation 1. The pressure of each action flow time adjusted properly adjusted. Each action near the switch position is inappropriate Proximity switch to adjust the appropriate 3. Solenoid valve failure or blocked oil solenoid valve or cleaning solenoid valve 4. Front and rear security door is not closed before and after the security door closed 5. Cam valve does not bounce Reset the cam valve 6. Safety device circuit check circuit 7. Not placed in a semi-automatic state Press the semi-automatic key 10 alarm ring to see the fault display on the screen according to the failure of the project to troubleshoot 11 electric eye failure 1. electric eye hair / Hair 2 power supply without electricity supply eye power supply 3 electric eye hair / hair device does not correspond to adjust Eye retractable hair / hair screw 4 no electric eye automatically state press the eye automatically switch 12 The alarm is not on 1. The alarm power supply is disconnected and the alarm is on 2. The alarm is faulty Replace the alarm bell 13 The rotation lamp is off 1. The rotation lamp power supply is disconnected and the rotation lamp is supplied with power 2. The rotation lamp is faulty Replace the rotation lamp 14 Microswitches and Proximity Switches Microswitches or Proximity Switches Can not Be Detected ON Can Detect Microswitches or Proximity Switches to be Replaced by Input / Output Monitor Modes (Page 6 Screen) 15 Insufficient Heating 1. Relay Failure Replacing Relays 2. Heatsink Burn out new heaters 3. Fuse circuit breakers to replace the new fuse 4. Probes on the probe temperature fault for the new probe temperature wire 5. Short circuit or ground inspection and repair 16 Oil temperature is too high 1. Long-term use of high pressure according to the actual needs Adjust the pressure 2. Oil pump wear or oil viscosity is too high Check the oil pump for lower viscosity of the working oil 3. Oil shortage Add hydraulic oil 4. Cooling water shortage Increase the amount of cooling water 5. Cooler blocked Replace the cooler 6. Water temperature is high Install the cooling tower 17 Directional valve Pressure valve noise 1. Adjust the pressure is not appropriate Spring arch Vibrate the pressure valve 2. Valve is stuck Remove and wash 3. Solenoid aging new electromagnetic coil 4. No electromagnetic force Poor wiring, Or undervoltage, check Repair 18 Oil Leakage 1. Cylinder Screw Loosen Lock Cylinder Screws 2. Damaged Oil Seal Replace New Oil Seal 3.
