6 COMMON EXCAVATOR PROBLEMS
Excavator is an important engineering machinery and equipment, but in the process of use may encounter some common failures. The following are some common failures and their analysis and repair techniques:
HYDRAULIC SYSTEM FAILURE
Failure Phenomenon: Loss of power in the hydraulic system, the fluid temperature rises, the hydraulic cylinder action is slow or can not move.
Analysis And Maintenance Techniques: Check the quality of hydraulic oil and oil level, cleaning or replacement of hydraulic filters, check whether the hydraulic pipeline leakage, check the hydraulic pump and hydraulic cylinder working condition, if necessary, replace the seals or repair hydraulic components.
ENGINE FAILURE
Failure Phenomenon: Engine starting difficulties, lack of power, black smoke, noise and so on.
Analysis And Maintenance Techniques: Check the fuel supply system to ensure the quality and smooth supply of fuel, check the air filter and exhaust system, check the ignition system and engine cooling system, if necessary, cleaning or replacement of the corresponding components.
ELECTRICAL SYSTEM FAILURE
Failure Phenomenon: Circuit failure, electrical equipment can not work properly, battery power is insufficient.
Analysis And Maintenance Techniques: Check whether the wire connection is loose or damaged, check the battery power and charging system, check the working status of switches and sensors, replace the wires, switches or sensors if necessary.
TYRE OR TRACK FAILURE
Failure Phenomenon: Tyre rupture, track falling off, abnormal tyre pressure, etc.
Analysis And Maintenance Techniques: Check the wear and tear of tyres or tracks, make sure the tyre pressure is appropriate, and replace broken tyres or repair tracks if necessary.
LUBRICATION AND MAINTENANCE PROBLEMS
Failure Phenomenon: Poor lubrication, wear and tear of parts, aging of equipment, etc.
Analysis And Maintenance Techniques: Regularly carry out lubrication and maintenance, check the lubrication points and the use of lubricant, and timely replace the parts that are badly worn to ensure that the equipment is in good working condition.
Please note that the above is only some of the analysis of common failures and maintenance techniques, the actual maintenance process should be based on the specific circumstances of the diagnosis and repair. For more complex faults or situations that require special technical knowledge, it is recommended to seek the help of professional excavator repair personnel. Meanwhile, the following are some tips for maintaining the excavator, which will help reduce failures and extend the service life of the equipment:
1. Regularly check and replace the hydraulic oil: Keep the hydraulic system in good working condition, regularly check the quality and level of the hydraulic oil and replace it according to the manufacturer’s recommendations.
2. Clean and protect the equipment: Clean the external and internal parts of the excavator regularly to prevent dust, mud and other substances from accumulating, and use protective measures, such as covers or guards, to protect important parts.
3. Regularly check and maintain the engine: Check the engine’s fuel system, cooling system and exhaust system, regularly change filters and maintain the ignition system.
4. Maintain the lubrication system: Ensure that the various lubrication points of the equipment are adequately lubricated, use appropriate lubricants, and regularly check the working conditions of the lubrication points and the lubrication system.
5. Perform regular inspection and maintenance of tyres or tracks: Check tyres or tracks for wear and tear, maintain proper tyre pressure, clean and lubricate regularly.
6. Carry out regular maintenance and servicing: According to the excavator’s manual or manufacturer’s recommendations, set up a regular maintenance programme, including replacing wearing parts, checking the electrical system, checking fasteners, etc.
7. Through reasonable maintenance and upkeep: You can reduce the probability of breakdowns, improve the working efficiency of the excavator, and extend the service life of the equipment.
