| The plunger does not rise after startup | ① The oil pump is not producing oil, which may be due to the pump turning in the opposite direction or being damaged. ② The return valve handle is in the open mold position. ③Motor reversal | ① Electrical test or disassembly for oil pump maintenance ② Pull the handle to the correct position ③Swap the live wires |
| 2 | Abnormal noise | ① There is a large amount of air in the pipeline ② Oil filter blockage ③ The oil level in the fuel tank is too low, and air is sucked into the pipeline ④ Oil pump damaged | ① Make the press up and down several times, exhaust the air ② remove and clean ③ add oil ④ remove and repair or replace |
| 3 | Will not boost or boost slowly | ① High pressure pump malfunction ② High pressure relief valve not closed ③ There is a leak on the pipeline ④ Pressure gauge malfunction | ① Disassemble, inspect and repair ② After disassembly and cleaning, adjust the pressure correctly. ③ Identify and remove any leaks ④ Replace the pressure gauge |
| 4 | Cannot maintain pressure | ① The valve seat and disc of the oil discharge valve are not tightly sealed ② The sealing of the valve core inside the one-way valve is not functioning properly ③ Pipeline or oil cylinder leakage reduction | ① ② Disassemble, clean, grind or modify ③ Check if the oil inlet pipe is loose, and then tighten it |
| 5 | Heating up slower than normal 1) The contactor often opens during the heating process. 2) A certain flat plate is not heating up or the temperature is low. 3) Continue heating up after reaching the specified value | ① Temperature controller malfunction ② The temperature control regulator malfunctions or some heating tubes are damaged ③ Temperature controller malfunction ①②③③③⑤⑥ | ① Replace the temperature controller ② Replace the temperature controller or heating tube ③ Replace the temperature controller |
| 6 | There is a large amount of oil leakage around the plunger | The sealing ring is broken | Replace the sealing ring |
| 7 | Abnormal heating of the tablet | Damaged thermistor | Measure the continuity of flat electric heating tubes with lower temperatures one by one, and replace damaged meters |
| 8 | Temperature control malfunction | ① Temperature controller malfunction or control circuit interruption ② Electric heating fuse circuit breaker or wiring circuit breaker | The temperature control instrument core can be removed and compared using the exchange method to replace the damaged meter |
| 9 | Heating does not display | ①Possible reason is that the ammeter is broken ②Perhaps the heating tube is damaged | Observe the pointer of the temperature controller. If the pointer rotates clockwise to the end, it indicates that the wiring of the thermistor is open or the thermistor is burnt out. |
| 10 | The tablet does not heat up | ① Thermal resistancedamaged ② Thermal resistanceThe connecting wires at both ends may burn out
| ① Use the exchange method to check or observe whether the electric contactor is working when the temperature controller is in operation, then connect and disconnect it, and replace the temperature controller. ② Swap the fast melting core or connect the circuit |
