Himachal Pradesh State Electricity Board Limited Tender

The job involves the complete dismantling of the threaded rod/shaft and gate limiter sleeve cylinder of the deflector servo motor of Unit No. 3 at Thirot Powerhouse. The dismantled components are to be carefully packed and safely transported to the contractor’s workshop for further repairs. At the workshop, the threaded rod shall be disassembled, inspected, and repaired by fabricating new threads (length: 940 mm, threaded portion: M24*180 mm) using welding, grinding, and precision machining techniques. Afterward, the gate limiter sleeve cylinder shall be repaired by restoring its grooves to ensure it fits snugly over the threaded rod and rotates smoothly on the threads. Once the repairs are completed, the threaded rod shall be aligned with the deflector servo motor piston to ensure smooth and efficient piston movement. The components will then be reassembled with precision. Following reassembly, the unit shall undergo thorough testing to verify proper functionality. Once the performance is confirmed, the reassembled components shall be transported back to Thirot Powerhouse. The final step involves commissioning the repaired threaded rod assembly of deflector servo motor , ensuring it is fully operational and meets all performance standards, completing the job in all respects.
