7), after each section of rigging out of vacuum pump, each section is attached centering location.
Step 3: welding
Vacuum pump is that split is marched into the arena Site Welding, and design drawing requires similar Q345 welding procedure, for ensureing being smoothed out of welding, first carries out qualification of welding procedure, and formulates welding procedure guiding book, need to use double welding in the same direction when welding, and welding completes.
According to on-the-spot actual state, the lifting of vacuum pump should be carried out three-dimensional simulation, identification segmentation position, lifting mode, hanging method etc. as in a preferred technical solution of the present invention, step one before lifting.
Prepare to put in place according to the work facility that hanging method is used to lifting before lifting as in a preferred technical solution of the present invention, step one.
As in a preferred technical solution of the present invention, step one, each position of vacuum pump body without support seat is increased bearing temporarily, ensure its rear dropping place smoothly in place.
As a preferred technical solution of the present invention, step 2 intermediate pump two-stage nitration uses direct lift-on/lift-off system to four sections, and vacuum pump one section uses upside-down method of hull-section construction, vacuum pump five sections to use temporary support lift-on/lift-off system.
As a preferred technical solution of the present invention, after each section of rigging out of step 2 intermediate pump, boil on the nape opposite the mouth centering to be carried out.
As a preferred technical solution of the present invention, the welding that step 3 intermediate pump is each section uses double two-way welding in the same direction.
The present invention has following main beneficial effect compared with other conventional mounting arrangements: does not affect the construction speed of normal factory building, and is well connected tight with the working procedure of steel construction.Save the construction procedure after lifting and lifting, save the holding time of large lifting equipment.Avoid that the structure of original steel-structure factory building causes large area remove to damage.In sum, the present invention to the progress of mill construction, operation is less impacts, construction speed usage quantity fast, mechanical is few；The mounting means that repeatedly split, positive upside-down mounting combine, efficiency is relatively high, reduced investment, and the actual lifting time is short, practical.
