Cannot initiate	Power line not conducting or motor phase failure	Inspect motor; connect power supply
2. Below rated speed	Belt elongation and slippage, or idler pulley misalignment	Replace the belt and ensure the tension pulley is properly positioned.
3. Engine front bearing overheating	Bearings damaged or excessive grease applied or too tight fit	Exchange bearings, match to specifications, and reduce grease as required.
4. The pressure roller is overheating severely.	As above.	As above.
5. Leakage at the bottom of the drum	Bottom cover seal ring or cylinder sealing end face damage	Replace the sealing rings and correct the seal end face of the cylinder (manufacturing can be outsourced)
6. Raw Material Nozzle Leak Detected at Night	Raw material pressure too low	Raw material pressure is within the specified range.
7. Insufficient clarity after separation	Excessive flow rate, or solid particle size or density exceeding the machine's separation capacity.	Refer to the preceding section.
8. Overflow of Foam and Liquids into the Catch Basin	Insufficient internal pressure within the housing, forgetting to place the sealing ring, or a blocked import channel.	Adjusted the ventilation holes at the bottom of the body and added sealing rings to maintain a clear exhaust passage.
9. Excessive vibration at high speed	Drum imbalance, main shaft deformation, minor pulley swing exceeds standard, lower damping failure, improper upper rubber pad installation	Refer to the preceding section for inspection and processing.
The lower part of the high-speed operation is making a knocking sound.	Lubricated bearings with excessive bearing clearance and failed lower damping.	Exchange oil-bearing bearings and check the damping.
11. Metallic shell vibration sound during exercise	Liquid Container Base Protective Cover Not Tightly Screwed or Shell Not Properly Secured	Tighten the retaining nut, secure the housing.
The lower drum cover is rubbing against the feeding nozzle.	Misalignment of nozzle installation or excessive outer diameter of the nozzle, oil bearing wear exceeding the allowable limit	As requested, improvements have been made.
13. Main shaft nut and protective sleeve in contact	Axles, nuts, and drum rotors were not properly installed, with protective sleeves and protective nuts, as well as the liquid-receiving plate, not correctly positioned or experiencing excessive vibration.	Precisely installed in place, see "9" models.
14. Excessive Machine Noise	Excessive vibration, lack of lubrication in bearings, or loose components that should be secured.	Lubricate or replace bearings, secure loose parts according to specifications, and refer to "9" model.
