Diesel generator sets are high-speed rotating equipment that must be installed correctly before use to ensure safe, reliable, and economically reasonable normal operation of the unit. Therefore, sufficient attention should be paid during installation. This section mainly introduces the installation methods and precautions of diesel generator sets and their auxiliary equipment.
(1) The handling and storage of the unit and other electrical equipment generally have packaging boxes. When handling, attention should be paid to tying the lifting steel cables to the appropriate parts of the machine and lifting them gently. When lifting the unit for installation, first connect the protruding lifting points on the chassis, and then check whether they are firmly attached, whether there are cracks in the welding joints, and whether the screws are tightened.
(2) Open the box for inspection, check if the box is damaged, verify the box number and quantity, and remember not to damage the unit when opening the box.
① List all units and accessories according to the unit list and packing list.
② Check if the main dimensions of the unit and accessories match the drawings.
③ Check the unit and accessories for damage and rust.
④ After opening the box, the unit should be carefully stored and placed flat. The flanges and various interfaces must be covered and wrapped to prevent rainwater and sand from entering.
If the unit cannot be installed in a timely manner after inspection, the disassembled parts should be re coated with anti rust oil on the precision machined surface and stored properly. Do not rotate or slide the transmission and sliding parts of the unit until the rust proof oil has been removed. If the rust proof oil has been removed during inspection, it should be reapplied after inspection.
(3) The marking and positioning shall be based on the dimensions of the relationship between each unit and the center of the wall or column, as well as between units, as indicated in the layout plan, to define the longitudinal and transverse reference lines for the installation location of the units. The allowable deviation between the center of the unit and the walls and columns is 20mm, and the allowable deviation between units is 10mm.
(4) Understand the design content, prepare construction materials and inspect equipment, understand the design content, understand the construction drawings, and refer to the instruction manual. Prepare materials according to the design drawings, and then deliver the materials to the site according to the construction organization plan.
(5) Prepare lifting equipment and installation tools
