Electrical system design for shale shaker equipment must address motor starting, protection, control, and hazardous area compliance. Aipu Solids Control provides electrical system design services that ensure safe, reliable shaker operation.
Power Supply and Distribution Design
Reliable shaker operation begins with adequate power supply. Aipu electrical system design verifies that the available supply matches equipment requirements: voltage within equipment tolerance, adequate capacity for starting current without unacceptable voltage drop, phase balance within motor tolerance, and frequency within equipment specification. Distribution design addresses cable sizing for voltage drop over the actual cable run length, protection device selection and coordination, isolation provisions for maintenance safety, and grounding design to equipment manufacturer requirements and applicable codes.
Motor Starting and Control
Shaker vibration motors require specific starting and control arrangements. Aipu designs motor starting systems appropriate for the application: direct-on-line starting where supply capacity permits, star-delta starting to reduce starting current on larger motors, or variable frequency drives where soft starting or variable speed operation is beneficial. Vibration motors typically operate in pairs and must start simultaneously to prevent unbalanced loading. Control circuit design includes start/stop logic, overload protection, phase loss and phase reversal protection, and status indication for remote monitoring.
Hazardous Area Compliance
Many shaker installations are in hazardous areas requiring explosion-protected electrical equipment. Aipu electrical system design addresses hazardous area classification of the installation location, selection of appropriately certified motors and electrical equipment, cable gland selection and installation to maintain enclosure integrity, and compliance with applicable standards including ATEX, IECEx, or regional certifications. Documentation of the hazardous area design basis is provided for operator review and regulatory compliance verification.
Control and Monitoring Integration
Electrical system design includes integration with rig control and monitoring systems. Motor starter status, running indication, and fault signals are interfaced to the rig control system. Analog signals—motor current, temperature, vibration—are connected to monitoring and data acquisition systems. Emergency stop circuits are integrated with rig-wide safety systems. Control system interfaces are designed with appropriate signal isolation to prevent ground loops and interference.
