Proven repair and intervention processes for turnkey services

For DV GROUP, the management of your sites is part of a comprehensive, expert-led solution. Our “Electromechanical Maintenance” department has expertise in factory shutdowns and emergencies involving both large power capacities and large product volumes. This expertise translates into an outstanding organisational method. A site manager manages all operations, from conducting the feasibility study to delivering the project in compliance with safety standards (prevention plan, etc.) and within the set time limit.

We offer two types of services: workshop repair and on-site intervention.

Repairs:

  • Expertise in all rotating electrical machines
  • Repairs and reconditioning according to the manufacturer’s specifications and current SaqrAtex standards
  • Winding: mechanical modification and adaptation
  • Test platform: load testing (mechanical, electrical and thermal)

Intervention:

  • Maintenance of shutdowns and 24/7 on-site services

Electromechanical maintenance experts available 24/7

We bring you effective solutions through individuals and resources organised into three divisions:

Electromechanical division:  This division provides maintenance for AC/DC motors and associated components such as reducers, pumps and fans, as well as transmission devices (bearings, couplings).

Resources:

  • Lifting: 10T / 4T / 3T2 / 1T5 bridges. 5T, 4T5 and 4T trolley jacks. 1T5 electric stackers.
  • Test benches: 800 A (full load). Analogue and digital dynamic variable speed drives: Induction motor

Mechanical tools: Presses: vertical and horizontal 50T / 100T / Mechanical and hydraulic extraction. Bearing heating by induction / T° control

Specific tools: Shock wave analysis, impedance analysis, vibration measurements, balancing, etc. Re-magnetisation bench (permanent magnets). Spare parts in stock (original equipment or adaptable)

Method:

Procedure established for each work phase with dedicated sheets:

  • Rigorous inspection of electrical and mechanical features according to manufacturer’s data: metrological inspection on bearing seating, joint surfaces, flanges, shaft, etc.
