As a commonly used mechanical equipment on construction sites, road rollers often encounter some faults, which will affect the normal progress of work. This article will introduce the common faults of road rollers and provide corresponding solutions to help workers quickly solve the problems and improve work efficiency.
Como equipo mecánico de uso común en obras de construcción, las aplanadoras suelen presentar fallas que afectan el progreso normal del trabajo. Este artículo presentará las fallas comunes de las aplanadoras y brindará soluciones para ayudar a los trabajadores a resolver los problemas rápidamente y mejorar la eficiencia del trabajo.
1. Engine failure/Fallo del motor
1) Difficulty or failure to start/Dificultad o imposibilidad de iniciar
Check the fuel supply: make sure there is enough fuel in the fuel tank and check whether the fuel filter is clogged. If so, replace and clean the fuel filter in time.
Check the power system: Check whether the battery connection is good and make sure the battery has enough power. If the battery power is low, charge or replace the battery in time.
Check the spark plug: Check whether the spark plug is damaged or dirty. If there is any problem, replace or clean the spark plug in time.
Check the fuel line: remove the fuel pipe and use a hand pump to pump oil to expel the air.
Solenoid valve inspection: If the solenoid valve is damaged, use a thin copper wire to temporarily fix the oil valve stem to ensure oil supply.
2) Black smoke/Humo negro
Check the fuel and air filter: If the fuel quality is poor, replace it with qualified diesel in time. If the air filter is clogged, clean or replace it in time.
Is the injection timing too late? Adjust the injection advance angle to avoid long-term high-load operation.
Check if the engine is overloaded.
Check if the water temperature or oil temperature is too high: whether the cooling water is insufficient or the thermostat is faulty and should be replaced or repaired in time.
Check whether the fan belt is loose. If so, adjust the belt tension in time.
2. Clutch failure/Fallo del embrague
1) The clutch is not completely disengaged/El embrague no está completamente desacoplado
Causes: Booster leakage, oil pipe leakage, friction plate sintering, etc.
Repair method:
Check and tighten the air pipe or oil pipe joints, and replace damaged friction plates.
Adjust the booster push rod stroke (free stroke 3-5mm).
2) Clutch slipping or overheating/El embrague patina o se sobrecalienta
Causes: Friction plate wear, pressure plate spring annealing, poor ventilation, etc.
Repair method:
Replace worn friction plates or springs and clean the clutch case cooling holes.
3. Hydraulic system failure/Fallo del sistema hidráulico
1) Weakness or inability to walk/Debilidad o incapacidad para caminar
Causes: Hydraulic pump wear, motor damage, oil circuit blockage, etc.
Repair method:
Check the hydraulic oil quantity and quality and replace the filter element.
Test pump and motor pressure and replace damaged parts if necessary.
2) Hydraulic system oil leakageFuga de aceite del sistema hidráulico
Check the hydraulic pipeline: carefully check whether the hydraulic pipeline connection is loose, if it is loose, tighten it in time. Check whether the pipeline is damaged or aged, if there is any problem, replace the hydraulic pipe in time.
Check the seals: Check the seals of the hydraulic cylinder and valves for damage or aging. If there are any problems, replace the seals in time.
Check the fuel tank: Check whether the fuel tank is damaged or the oil seal is loose. If there is any problem, repair or replace the fuel tank in time.
4. Abnormal vibration system/Sistema de vibración anorma
Check the vibration wheel: Check whether the vibration wheel is loose or damaged. If there is any problem, tighten or replace the vibration wheel in time.
Check the drive belt: Check whether the drive belt is worn or loose. If there is any problem, replace or adjust the drive belt in time.
Check the vibration motor: Check whether the vibration motor is operating normally. If the motor fails, repair or replace the motor in time.
5. Travel and steering system failure/Fallo del sistema de viaje y dirección
1) Walking deviation/Desviación de la marcha
Causes: uneven tire pressure, unilateral brake failure, hydraulic motor failure, etc.
Repair method:
Adjust tire pressure, check brake system, and repair leaking hydraulic lines.
2) Difficulty in turning/Dificultad para girar
Causes: Steering oil pump damage, pipeline oil leakage, steering gear wear, etc.
Repair method:
Check the oil pump pressure and replace any damaged seals or steering gear.
6. Heating system failure/Fallo del sistema de calefacción
Check the water temperature: Check whether the water level in the cooling water tank is normal. If not, add water in time. Check the engine water temperature gauge to ensure that the water temperature is normal.
Check the radiator: Check if the radiator is clean. If it is dirty, clean it in time. Check if the radiator is damaged. If there is any problem, replace it in time.
Check the water pump: Check whether the water pump is working properly. If there is any problem, replace or repair the water pump in time.
7. Transmission system failure/Falla del sistema de transmisión
Check the gearbox: Check whether the gearbox shifts smoothly. If not, repair or replace the gearbox in time.
Check the clutch: Check whether the clutch is normal. If there is wear or failure, replace or repair the clutch in time.
Check the drive shaft: Check whether the drive shaft is loose or damaged. If there is any problem, tighten or replace the drive shaft in time.
8. Other common faults/Otras fallas comunes
Poor positioning of the gear lever
Cause: The positioning pin fell off or cut off.
Repair method:
Expand the hole and tap the thread, then use M6 screws to fix it to prevent it from falling off.
Deformation of front wheel support
Cause: external impact or improper starting method.
Repair method:
Use a jack to lift up the deformed part, and then weld and reinforce it after correction.
9. Misunderstandings about maintenance/Malentendidos sobre el mantenimiento
The engine oil is only added but not changed: the old oil contains impurities and needs to be changed regularly.
Grinding bearings with emery cloth: Sand particles embed into the alloy and accelerate wear.
Over-tightening of bolts can easily cause thread stripping or breakage.
Summarize/Resumir
Roller failure involves multiple systems, and the cause needs to be determined based on the specific performance and appropriate measures taken. Regular maintenance (such as replacing the filter element and checking the oil) can significantly reduce the failure rate. For complex problems, it is recommended to contact professional maintenance personnel.
Las fallas de los rodillos afectan a varios sistemas, y la causa debe determinarse en función del rendimiento específico y las medidas adecuadas adoptadas. El mantenimiento regular (como el reemplazo del filtro y la revisión del aceite) puede reducir significativamente la tasa de fallas. Para problemas complejos, se recomienda contactar con personal de mantenimiento profesional.
