Failure causes: ① power supply is out of phase (Solution: check the power supply) ② auditing current limiter value is too low (solution: adjust the value of the current limiter and then press the reset button RESET) ③ pump short circuit rotor bearing damage

Cause of failure: ① computer board damage (Solution: replace or repair the computer board) ② Fuse damage (Solution: replace the fuse) ③Button switch poor contact (Solution: replace the button switch)

Cause of failure: ① Cooling water system pressure is not enough (Solution: increase the cooling water system pressure in accordance with the factory settings) ② Solenoid valve damage (solution: replace the solenoid valve) ③ pressure switch misoperation (solution: replace the pressure switch) ④Piping system blockage (Solution: check whether the media piping is blocked)

Cause of failure: ①Heating AC contactor stuck (Solution: replace the AC contactor) ② computer board heating has been output (solution: replace the computer PC board) ③ over-temperature protection switch misoperation (solution: replace the over-temperature protection switch)

Cause of failure: solenoid valve blockage or solenoid valve coil aging Solution: clean or replace the solenoid valve

Fault cause: power phase sequence error Solution: Close the total power supply of the mold temperature machine, the power line in any two power lines interchange, if still alarm, replace the reverse phase protector. For the solution to common failures of the mold temperature machine to share this, in the daily use of the process, although the mold temperature machine does not belong to the frequent need for special maintenance, but also to regularly observe and check, in order to find abnormalities in a timely manner to ensure production efficiency and product quality.

To keep the water clean cooling towers, water towers and keep the air circulating around the low temperature, to avoid any debris into the towers, reduce cooling efficiency.

Reduce mold "inverted sweat" generation, before stopping plastic machine, die of cold water first subsidiary towing off, or turn off the chiller, which makes the cavity water temperature rises, so that the mold will not rust.

Such as chiller has been used for more than three months, the high and low pressure are often faulty, or cooling capacity decreases, please arrange for staff to clean the heat gun (high pressure gauge pressure than 20MP, please clean the heat gun, or check whether the switch is open to do Shuihou ).

What cleaning chiller? Cooling water systems: Recommended use of aqueous hydrochloric acid (1:10 conducted with dollar),
