Common faults and troubleshooting methods of road rollers

I. Engine failure
1. The engine cannot start
Failure causes: insufficient fuel, insufficient battery power, starter motor failure, ignition system failure, etc.
Troubleshooting methods: Check the fuel tank and add enough fuel; check the battery power, charge or replace the battery; check the starter motor and ignition system, and repair or replace the faulty parts.
2. Insufficient engine power
Failure causes: air filter blockage, fuel filter blockage, fuel injector blockage, engine wear, etc.
Troubleshooting methods: Clean or replace the air filter and fuel filter; clean or replace the fuel injector; overhaul the engine and replace worn parts.
3. Engine overheating
Failure causes: insufficient coolant, radiator blockage, fan failure, water pump failure, etc.
Troubleshooting methods: add enough coolant; clean the radiator; check the fan and water pump, and repair or replace the faulty parts.
II. Hydraulic system failure
1. The hydraulic oil temperature is too high
Failure causes: insufficient hydraulic oil, hydraulic oil pollution, radiator blockage, hydraulic pump or motor failure, etc.
Troubleshooting: Add enough hydraulic oil; replace hydraulic oil and filter; clean radiator; check hydraulic pump and motor, repair or replace faulty parts.
2. Hydraulic system leakage
Failure cause: damaged seals, loose pipe joints, worn cylinders, etc.
Troubleshooting: Replace damaged seals; tighten pipe joints; overhaul the cylinders and replace worn parts.
3. Insufficient hydraulic system pressure
Failure cause: hydraulic pump failure, overflow valve failure, pipe blockage, etc.
Troubleshooting: Check hydraulic pump, repair or replace faulty parts; check overflow valve, adjust pressure or replace faulty parts; clean pipes and eliminate blockages.
3. Vibration system failure
1. Abnormal vibration frequency
Failure cause: vibration pump failure, vibration motor failure, control valve failure, etc.
Troubleshooting: Check vibration pump and vibration motor, repair or replace faulty parts; check control valve, adjust or replace faulty parts.
2. Vibration is weak
Failure cause: insufficient hydraulic oil, wear of vibration pump or motor, damage to eccentric block, etc.
Troubleshooting method: add enough hydraulic oil; inspect the vibration pump and motor, replace the worn parts; replace the damaged eccentric block.
3. The vibration system does not work
Fault cause: circuit fault, fuse blown, solenoid valve fault, etc.
Troubleshooting method: check the circuit and repair the fault; replace the blown fuse; check the solenoid valve, repair or replace the faulty parts.
IV. Walking system failure
1. Walking powerlessness
Fault cause: insufficient hydraulic oil, walking pump or motor failure, transmission system failure, etc.
Troubleshooting method: add enough hydraulic oil; check the walking pump and motor, repair or replace the faulty parts; inspect the transmission system and replace the worn parts.
2. Walking deviation
Fault cause: inconsistent tire pressure, inconsistent track tension, steering system failure, etc.
Troubleshooting method: adjust the tire pressure to make it consistent; adjust the track tension to make it consistent; check the steering system, repair or replace the faulty parts.
3. The walking system cannot brake
Fault cause: brake system failure, brake pad wear, brake oil circuit blockage, etc.
Troubleshooting: Check the brake system, repair or replace faulty parts; replace worn brake pads; clean the brake oil circuit and remove blockages.
V. Other faults
1. Instrument panel fault
Fault cause: sensor fault, circuit fault, instrument panel fault, etc.
Troubleshooting: Check the sensor and circuit, repair or replace faulty parts; replace the instrument panel.
2. Operating handle fault
Fault cause: loose handle connection, damaged internal parts, etc.
Troubleshooting: Tighten the handle connection; check the internal parts of the handle, repair or replace the faulty parts.
