What Should Be Noted When Storing Second-hand Rotary Drilling RIGS for A Long Time? Key Steps for Moisture-proofing And Rust Prevention

When second-hand rotary drilling RIGS are stored for a long time, due to their prolonged idleness, moisture intrusion and metal rust are the main risks. If they are not properly maintained, it can lead to component damage and performance degradation. Proper moisture-proof and rust-proof treatment is the key to ensuring the stable operation of the equipment when it is reactivated. The following are the specific operation steps.

1. Choose the right storage location: Prioritize indoor dry warehouses. If stored outdoors, a rain shelter should be built. The site needs to be leveled and hardened. A wooden block 10 to 15cm high should be placed at the bottom of the drilling rig to prevent the machine body from directly contacting the ground moisture.

2. Thoroughly clean the equipment: Before storage, thoroughly remove the dirt and sand from the machine body. Use a high-pressure water gun to rinse the chassis, tracks (or tires), and then dry the surface moisture with a cloth. Pay special attention to cleaning the engine, hydraulic oil tank and other parts to prevent residual impurities from mixing with moisture and causing malfunctions.

3. Drain moisture-prone liquids: Drain the cooling water in the water tank to prevent it from freezing and cracking at low temperatures. At the same time, drain the fuel in the fuel tank or add fuel stabilizer to prevent the fuel from deteriorating. Replace the old hydraulic oil in the hydraulic system, inject new oil and start the equipment circulation to expel the residual moisture in the system.

4. Rust prevention for key parts: For exposed metal components (such as drill pipe joints, bolts, and cylinder piston rods), sand off the rust with sandpaper and then apply anti-rust grease. Place desiccants in the cab, engine compartment and other parts, check and replace them regularly to keep the interior dry.

5. Sealing and protective treatment: Cover the entire drilling rig with waterproof plastic film or special cover cloth to ensure that the cover cloth fits closely and prevent rainwater and dew from seeping in. Seal the engine's air intake, exhaust ports and hydraulic oil filling ports to prevent moisture from entering the internal systems.

6. Regular inspection and maintenance: Open the cover cloth every 1-2 months to check the equipment condition, and verify whether the anti-rust layer is intact and whether the desiccant has lost its effectiveness. Start the engine and let it idle for 10 to 15 minutes to allow the hydraulic system to circulate and prevent components from getting stuck due to long-term inactivity.

In conclusion, for the long-term storage of second-hand rotary drilling RIGS, moisture and rust prevention should be carried out in six major steps: site selection, cleaning, liquid drainage, rust prevention, sealing, and inspection. Through scientific and standardized maintenance, the damage caused by moisture and rust to equipment can be minimized to the greatest extent. This ensures that when the equipment is put back into use, it can quickly regain its operational capacity without extensive repairs, thereby reducing maintenance costs.
