Application of BIM Technology in the Assembly Engineering of Ultra-Large Single-Stage Single-Suction Vertical Centrifugal Pumps
In response to the problem of high eccentricity caused by two-dimensional design during the assembly process of ultra-large single-stage single-suction vertical centrifugal pumps,a construction technology based on BIM technology is proposed for the assembly of ultra-large single-stage single-suction vertical centrifugal pumps,taking the pump units in the Shushan Pump Station Project as the research object.By dividing the pump structure into multiple modules and establishing a three-dimensional simulation model,accurately describing the position of complex components,key components are pre-assembled and processed in advance.On-site,materials are transported using cranes and ground tanks,assembled in sequence,and fine-tuned based on operational data.The construction results indicate that under the designed water flow rate of 25m3/s and a rotational speed of 7000r/min,the pump head reaches 221.5 meters,meeting the pump station's operational requirements.This study provides a new method for the efficient assembly of ultra-large pumps,ensuring engineering quality and efficiency.
