If abnormal noise (grinding, squealing), overheating, or uneven vibration is found, stop the motor immediately for inspection to avoid expanding the fault (e.g., bearing damage or eccentric weight misalignment).

• After stopping the motor: Clean the motor surface and spare parts to remove dust, mud, and abrasive particles—pay special attention to the cooling fins and seal surfaces. Check the oil level (for SG2X series with lubrication systems) and seal integrity; if oil leakage is found, replace the oil seal immediately. Store spare parts in a dry, dust-proof warehouse if not installed, and apply anti-corrosion oil to metal components to prevent rust.

7.2 Regular Maintenance (According to Working Hours)

• Every 500 Working Hours: Inspect the motor’s seals and gaskets for aging or damage; replace them if cracks, hardening, or leakage is found. Check the mounting bolts for tightness and corrosion; retighten or replace them if necessary. Clean the terminal blocks and wiring harnesses to remove dust and ensure good electrical connections.

• Every 1000 Working Hours: For SGX/SG3X series—inspect the permanently lubricated bearings for abnormal noise or overheating; replace the bearings if wear is detected. For SG2X series—check the lubrication system’s oil level and oil quality; replace the oil and oil filter if the oil is contaminated or degraded. Inspect the eccentric weights for wear or loosening; retighten the weight bolts if needed.

• Every 2000 Working Hours: Disassemble and inspect the rotor and stator assemblies; clean the stator windings to remove dust (use compressed air, avoid damaging insulation). Check the shaft for wear or bending; polish or replace the shaft if scratches or deformation are found. Inspect the explosion-proof enclosure (SGX/EX series) for damage to flameproof joints; repair or replace the enclosure if necessary.

• Every 3000 Working Hours: Replace core components—including bearings, seals, and eccentric weights (if worn). Conduct a comprehensive vibration test and electrical performance test (insulation resistance, phase resistance) to ensure the motor operates within DERRICK’s specifications. Replace the stator windings if insulation resistance is below 1MΩ (at 25℃).

8. On-Site Fault Maintenance Cases

The following 4 real on-site fault cases are common problems encountered in DERRICK vibrating motor operation (covering SGX, SG2X, and SG3X series). Each case includes fault phenomenon, judgment, maintenance method, and preventive measures—providing practical reference for on-site maintenance personnel. All maintenance uses our genuine spare parts to ensure stable, long-lasting results:

Case 1: SGX-44-15-380/400-5-001 Motor Bearing Overheating & Abnormal Noise

• Fault Phenomenon: A DERRICK drilling shaker motor (SGX-44-15-380/400-5-001, 1500 RPM, 380/400V 50Hz) emits abnormal grinding noise during operation, and the bearing temperature rises to 110℃ (exceeding the safe limit of 95℃). The motor’s vibration intensity decreases, leading to poor drilling fluid screening efficiency.

• Fault Judgment: On-site inspection found that the permanently lubricated sealed bearing was worn (used for 1200 working hours), with grease degradation and metal particles inside the bearing. The bearing inner ring was scratched due to dust entry (seal damage), causing increased friction and overheating.

• Maintenance Method: Stop the motor and disconnect the power supply; remove the motor from the shaker; replace the worn bearing with our genuine permanently lubricated bearing (matched to SGX-44-15-380/400-5-001); replace the damaged oil seal to prevent dust entry; clean the bearing housing and apply a thin layer of recommended grease; reinstall the motor and test run—bearing temperature drops to 75℃, abnormal noise disappears, and vibration intensity is restored to normal.

• Preventive Measures: Inspect bearings for overheating and noise every 500 working hours; replace bearings every 1000-1200 working hours; check seals regularly to prevent dust entry, especially in dusty drilling environments.

Case 2: SG3X-44-18-460/480-6-001 Motor Vibration Uneven & Screening Inefficiency

• Fault Phenomenon: A DERRICK mining screening motor (SG3X-44-18-460/480-6-001, 1800 RPM, 460/480V 60Hz) operates with uneven vibration; the screening equipment fails to separate solids and liquids effectively, and the motor’s housing has obvious shaking. Upon inspection, one of the eccentric weights is loose.

• Fault Judgment: The eccentric weight bolts are loose due to continuous high vibration, causing the weight to shift—resulting in uneven vibration output. The weight surface has slight wear, which further exacerbates the imbalance. This issue is common in mining applications where vibration intensity is high.

• Maintenance Method: Stop the motor and disconnect the power; remove the motor’s end cover; retighten the eccentric weight bolts to the specified torque (per DERRICK’s guidelines); replace the worn eccentric weight with our genuine model-specific weight (matched to SG3X-44-18-460/480-6-001); balance the rotor assembly to ensure smooth operation; reinstall the end cover and test run—vibration becomes even, and screening efficiency is fully restored.

• Preventive Measures: Check eccentric weight bolts for tightness every 300 working hours; inspect weights for wear every 1000 working hours; replace weights if wear exceeds 5% of the original weight.

Case 3: SG2X-36-18-460/480-6-001 Motor Lubrication System Failure

• Fault Phenomenon: A DERRICK dewatering motor (SG2X-36-18-460/480-6-001, 1800 RPM, 460/480V 60Hz) shuts down automatically due to overheating. Inspection shows the lubrication system’s oil level is low, and the oil is contaminated with metal particles—causing bearing friction and overheating.

• Fault Judgment: The lubrication system’s oil filter is clogged with dust and metal particles, preventing oil circulation; the oil pump is worn, reducing oil flow. The contaminated oil fails to lubricate the bearings effectively, leading to overheating and automatic shutdown.

• Maintenance Method: Stop the motor and cool it down; drain the contaminated oil from the lubrication system; replace the oil filter and worn oil pump with our genuine SG2X series spare parts; refill the system with DERRICK-recommended lubricating oil; clean the oil reservoir and oil lines to remove debris; restart the motor—oil circulation is restored, bearing temperature remains stable at 70℃, and the motor operates normally.

• Preventive Measures: Check oil level and quality every 500 working hours; replace the oil filter every 1000 working hours; replace lubricating oil every 2000 working hours; clean the oil reservoir regularly to prevent contamination.

Case 4: SGX-30-18-460/480-6-001 Motor Electrical Short Circuit

• Fault Phenomenon: A DERRICK wastewater treatment motor (SGX-30-18-460/480-6-001, 1800 RPM, 460/480V 60Hz) fails to start, and the power supply breaker trips immediately. Inspection shows the stator winding insulation is damaged, causing a short circuit.

• Fault Judgment: Moisture and chemical contaminants (from wastewater treatment) entered the motor through a damaged seal, damaging the stator winding insulation. The explosion-proof enclosure’s flameproof joint was intact, but the terminal block seal was worn, allowing moisture entry.

• Maintenance Method: Disconnect the power supply; remove the motor’s terminal cover and stator assembly; replace the damaged stator winding with our genuine model-specific winding (matched to SGX-30-18-460/480-6-001); replace the worn terminal block seal and oil seal; clean the stator and terminal block to remove contaminants; test the insulation resistance (now 2MΩ, above the safe limit of 1MΩ); reinstall the motor and test run—the motor starts normally, with no short circuit or tripping.

• Preventive Measures: Inspect seals and insulation resistance every 500 working hours; replace seals if wear is detected; keep the motor’s surface clean to prevent chemical contamination; store spare stator windings in moisture-proof packaging.
