How to Maintain Explosion Proof Shale Shaker Motors

Proper maintenance of explosion proof shale shaker motors is essential for both safety and equipment longevity. Explosion proof motors are precision-engineered assemblies where every seal, gasket, and cable entry is critical to maintaining the flameproof protection concept. Aipu Solids Control provides detailed maintenance guidelines for the premium Ital-Vibras, Martin, and Oli explosion proof motors installed on its shaker range, ensuring that operators can perform required service without compromising the hazardous area certification.

Daily and Weekly Inspection Points

Daily motor inspections should verify that all cable glands and entries are tight and that no conductors are exposed. The motor terminal box cover fasteners must be fully seated with no missing bolts. Visual checks should confirm that the motor surface is clean and free from accumulated dust or drilling fluid residue that could insulate the motor and cause surface temperature rise. Weekly inspections include measuring insulation resistance between phases and to ground using a certified megohmmeter, with readings documented for trending. The motor mounting bolts should be checked for proper torque, as loose mounts can increase vibration and accelerate bearing wear. For the Hunter-MG4D double-deck configuration with 5.4 square meters screen area and dual motor systems, both upper and lower deck motors must be independently inspected following the same procedure.

Scheduled Preventive Maintenance

Every 2000 operating hours, explosion proof motors should receive bearing lubrication using the grease type and quantity specified by the manufacturer. Over-greasing can cause overheating and compromise the flameproof enclosure by building internal pressure. Every 4000 hours, a certified electrical technician should open the terminal box for internal inspection, checking for signs of moisture ingress, terminal corrosion, or insulation degradation. The flameproof joint surfaces must be cleaned and recoated with the specified anti-corrosion compound before reassembly. Aipu recommends maintaining a complete spare motor kit including terminal box gaskets, cable glands, and certified fasteners to ensure that any repair work uses only approved components. Documenting all maintenance activities is essential for maintaining the equipment certification and demonstrating ongoing compliance to regulators and clients.
