Rust prevention and storage methods for Volvo EC500 Electric excavator parts

The following is a professional method for rust prevention and storage of Volvo EC500 Electric excavator parts, formulated based on the characteristics of the electric vehicle model:
️ ‌ Core protective measures ‌
Pre-treatment cleaning ‌
Thoroughly remove oil stains and dust from the surface of the accessories. Evenly apply ‌ anti-rust grease ‌ to exposed metal parts (such as the piston rod of the hydraulic cylinder and the cutting edge of the bucket) to form an isolation layer ‌.
The areas where the paint has peeled off need to be repainted with the original factory anti-rust paint to prevent the steel plate from being directly exposed to a humid environment ‌.
Dry storage environment ‌
The preferred indoor warehouse is ‌ : the humidity should be controlled at 40%-60%, wooden boards should be laid on the floor to isolate ground moisture, and the distance between accessories and walls should be more than 50cm to ensure ventilation ‌.
Outdoor temporary storage ‌ :
Cover the seams with a waterproof tarpaulin to prevent rainwater from seeping in ‌;
Raise the bottom of the accessories by more than 30cm to prevent water accumulation and corrosion ‌.
Special protection for power systems ‌
Lithium battery pack ‌ : Disconnect the high-voltage relay (model 20797920), store separately in a fireproof and explosion-proof cabinet, and maintain the ambient temperature at 5°C-25°C‌.
High-voltage wiring harness interface ‌ : Seal the plug with a silicone sealing cap to maintain the IP67 protection level ‌.
️ ‌ key operating specifications ‌
Hydraulic system processing ‌ :
Retract all hydraulic cylinders, apply grease to exposed piston rods and then cover them with dust covers ‌;
Replace contaminated hydraulic oil. B series pilot filter (model 0332) should be sealed and stored ‌.
Maintenance of moving parts ‌ :
The track support axle is coated with high-temperature lithium-based grease, and the chain is wound with anti-rust paper to prevent oxidation ‌;
Operate the rotary mechanism 2-3 times a month to prevent the bearings from rusting and seizing ‌.
🔄 ‌ periodically maintains ‌
Key points of cycle ‌ ‌ operation ‌
Weekly ‌ check the integrity of the cover cloth and remove surface condensation water; Verify whether the seal is aged ‌
Every month, ‌ start the electric system to test the insulation resistance (> 500MΩ), and run the hydraulic function for a short time to lubricate the pipeline ‌
Before long-term storage, charge the ‌ battery to 50% of its capacity, disconnect the negative cable and recharge it regularly ‌
Note: For electric models, direct sunlight should be avoided to prevent cracking of rubber parts. Sensitive electronic components are recommended to be packaged in anti-static bags ‌.
