Many industrial parks and chemical facilities around the world are located in seismic active zones. When an earthquake occurs, the strong vibration will impact all fixed equipment in the factory. Pumps connected with rigid pipelines are prone to fixing base loosening, pump body displacement and connection pipeline fracture under seismic action. Once the corrosive medium leaks due to pipeline rupture, it will cause serious secondary safety accidents and increase the difficulty of post-earthquake rescue and disposal.
The seismic reinforced pump configuration adopts thickened integrated metal base, and the fixing bolt holes are designed with reinforced edge structure to improve the overall structural strength of the base. All fixing fasteners adopt anti-loosening locking structures to prevent bolt loosening caused by long-term vibration and seismic impact. The connection between the pump unit and the pipeline is matched with flexible shock-absorbing joints, which can absorb a certain amount of displacement deformation during an earthquake and avoid pipeline fracture caused by rigid connection.
All seismic reinforced pump units undergo simulated vibration tests according to corresponding seismic intensity standards to verify the structural stability under horizontal and vertical vibration impact. The seismic performance meets the general anti-seismic requirements of industrial equipment in most high-seismic-risk regions. For special high-intensity seismic areas, targeted structural reinforcement design can be further carried out according to local seismic fortification standards.
The anti-seismic optimized pump configuration improves the safety level of fluid equipment in high-seismic-risk industrial zones, reduces the secondary disaster risk of chemical plants and wastewater treatment stations under earthquake disasters, and enriches the product safety attribute system of Yida pumps in the global special environmental application market.
