Issue 1: Abnormal Operation Noise‌ of Cassava Paddle Washer

‌Motor Squealing‌

Cause‌: Insufficient lubrication or wear of motor bearings of cassava paddle washing machine.

Troubleshoot: Regularly inject high-temperature resistant grease through the oil filler port (recommended every 500 hours).

‌Paddle Friction Noise‌

Cause‌: Hard impurities (e.g., stones) in the raw cassava roots or deformed paddles

Troubleshoot: Install a cassava dry sieve for raw material pre-treatment. Inspect paddle clearance (normal range: 1–3 mm) and correct deformed paddles after shutdown.

Issue 2: Pressure Abnormalities‌ of Cassava Paddle Washer

‌Fluctuating or Intermittent Pressure‌

Cause‌: Air intake due to poor sealing in the water inlet pipeline or insufficient water supply pressure.

Troubleshoot: Check sealing at pipeline joints (use hose clamps for tightening), clean the inlet filter, and ensure water pressure ≥ 0.2 MPa.

‌Pressure Fails to Reach Rated Value‌

Cause‌: Excessive nozzle wear (recommended replacement cycle: 300 hours) or pump seal failure of cassava washing machine.

Troubleshoot: Replace with tungsten carbide nozzles of matching specifications. Inspect and replace the pump’s double-lip seal rings.

Issue 3: Reduced Cleaning Efficiency‌ of Cassava Paddle Washer

‌Excessive Residue‌

Cause‌: Low paddle rotation speed (recommended: 25–35 rpm) or uneven material density.

Troubleshoot: Adjust inverter parameters to achieve rated speed. Install flow guide plates to optimize material distribution.

‌Cloudy Cleaning Fluid‌

Cause‌: Clogged wastewater tank filters or excessive impurities in the clean water tank.

Troubleshoot: Clean the wastewater tank float daily. Wash the clean water tank filter weekly

Issue 4: Shaft End Powder Leakage‌ of Cassava Paddle Washer

Cause‌: Aged seals (typical lifespan: 6–12 months) or seal failure due to negative pressure operation4.

Troubleshoot: Replace with double-lip air-tight seals. Install a nitrogen gas sealing system (pressure: 0.02–0.05 MPa)

Issue 5: Motor Overload‌ of Cassava Paddle Washer

Cause‌: Material clogs or insufficient V-belt tension (below 30% of standard value)

Troubleshoot: Install an online moisture detector (control material humidity ≤ 15%). Adjust belt tension using an automatic tensioner.
