Condition of failure | Cause (in processing) | remedy |
|
---|
Even if shutter is opened and mist adjusting knob is turned during automatic operation, neither pointer of water flow meter works nor mists. | Power switch of water pump unit is off. | Turn on the power switch. | Water valve in the way of line is not open. | Open the valve. | Failure of solenoid valve for water. | Make electrical checks. | Clogging strainer or filter. | Disassemble and remove dust,etc. If repair is impossible, replace it. | Clogging needle valve or nozzle. | Exchange filter element. Disassemble and clean. |
|
Point of water flow meter is unstable. | Air mixed in the water. | Take out nozzle and allow water to flow unit, air is removed from the pipe. | Clogging strainer and filter. | Disassemble and clean. | Clogging needle valve, solenoid valve or nozzle. | Disassemble and clean. |
|
Misting is normal but pointer of flow meter does not indicate. | Failure of water flow meter. | Check and if impossible to repair, replace it. |
|
Water flowrater does not increase even though the mist adjusting knob is opened maximum. | Water pressure is too low. | Check water pump unit and adjust water pressure. | Cause of 1.3~5. | Disassemble and clean. |
|
Air does not come out even though the mist start button is pressed. Otherwise air quantity is small. | Air pressure is too low. | Check pressure gauge and adjust water pressure. | Full of water in the mist separator and micro-mist separator. | Drain it. |
|
Misting stops during automatic operation. | Mechanical and electrical failure of level meter. | Check and if impossible to repair, replace it. |
|
Miting does not stop during automatic operation, even if raw material is out. | Electrical failure of level meter. | Check and if impossible to repair, replace it. |
|
Bran sticks to cleaned rice. | Bran sticking to bran collecting duct. | Clean the duct. | Lack of bran suction (static pressure) | Increase static pressure. | Too much mist. | Adjust to the proper flow rate. | Improper mounting of dividing rubber plate. | Adjust to the proper flow rate. |
|
Bran sticks to the milling roll. | Improper mounting of dividing rubber plate. | Adjust to the proper flow rate. | Water leakage due to failure of solenoid valve. | Check and if impossible to repair, replace it. |
|
Temperature rise of rice is too high . | Bran sticking to the polishing chamber. | Clean the polishing chamber. | Water supply is stopping. | Check water supply line and water pump unit. | Screen is blinded with broken rice. | Clean the inlet. |
|
No flow. | Bran sticking at the inlet. | Clean the inlet. |
|
Discharge is difficult. | Mist leakage is due to damage of the dividing plate, and the amount added by the leakage is smaller than the standard. | Check and if impossible to repair, replace it. |
|
Water pump intermittently stops for a while. | Water pump gets over heating since too high water pressure. | Check water pump unit and adjust water pressure. |
