Repair and maintenance of a used excavator is an important part of ensuring the normal operation of the machine and prolonging its service life. The following will be introduced from two aspects of repair and maintenance.
I. Maintenance
1. Regular inspection: Regularly carry out a comprehensive inspection of the excavator, including the engine, the hydraulic system, the transmission system, the electrical system and other parts of the inspection, and find problems in time to repair.
2. spare parts replacement: according to the use of excavators, timely replacement of badly worn parts, such as lubricants, filter elements, belts, etc., to ensure the normal operation of the machine.
3. Troubleshooting: For the excavator that has malfunctioned, it is necessary to carry out troubleshooting and repair. You can locate the problem by checking the fault code, fault light, fault sound, etc., and repair the problem according to the specific conditions.
4. Hydraulic system repair: the hydraulic system is an important part of the excavator, you need to regularly check the quality of the hydraulic oil and oil leakage, and timely replacement of hydraulic oil and repair leakage problems.
5. electrical system repair: the electrical system is an important control system of the excavator, you need to regularly check the connection of wires, connectors, sensors and other components, and timely repair of broken wires, loose and other problems.
Maintenance
1. Lubrication maintenance: the various parts of the excavator need to be lubricated regularly, including the engine, hydraulic system, transmission system and so on. The quality and service life of the lubricant has an important impact on the operating effect of the machine, and the lubricant and filter element need to be replaced regularly.
2. Cleaning and maintenance: Regular cleaning of the excavator, including exterior cleaning and internal cleaning. External cleaning can prevent the machine from corrosion and oxidation, and internal cleaning can prevent dust and impurities from damaging the machine.
3. Adjustment and maintenance: the various parts of the excavator need to be adjusted regularly, including the chain tension, track alignment, hydraulic system adjustment, etc., to ensure the normal operation of the machine.
4. Rust prevention and maintenance: the metal parts of the excavator are susceptible to oxidation and corrosion, and need rust prevention treatment. Rust prevention and maintenance can be carried out by spraying rust preventive agent, regular cleaning and applying rust preventive oil.
5. Seasonal maintenance: according to different seasons, the excavator’s maintenance methods are also different. In summer, you need to pay attention to the maintenance of the cooling system; in winter, you need to pay attention to the anti-freezing maintenance.
In short, the maintenance of used excavators is an important part of ensuring the normal operation and extending the service life of the machine. Regular inspection, parts replacement, troubleshooting, hydraulic system maintenance, electrical system maintenance, etc. is the important content of maintenance; lubrication maintenance, cleaning maintenance, adjustment maintenance, rust maintenance, seasonal maintenance, etc. is the important content of maintenance. Only by doing a good job of repair and maintenance can we ensure the normal operation and efficient work of the excavator.
