The Design And Research Of Yongfeng Irrigation Pumping Station Renovation Project In Changfeng County

Anhui Province,in the province of agricultural irrigation pumping station segment is wide,the number of large,the survey found that the majority of agricultural irrigation pumping station of the situation is not optimistic,the construction of low standard,pumping station,pumping station serious aging problems such as the heavy burden of ten prominent,largepumping station renovation needed.Agricultural irrigation pumping station renovation project is a comprehensive systems engineering,the implementation of the transformation of pre pumping station should hydrology,water resources for a comprehensive investigationof pumping station,the design parameters and technical and economic indicators to conduct a comprehensive review,the timely adjustment,to adapt to the changing situation.On this basis,the pumping station by model test and field test by a professional organization,technical condition of the pumping station to make the analysis judgment.Then the technology to rebuild need to pump,the motor and the driving device,the inlet and outlet pipe,inlet and outlet building link,ensure and improve the efficiency of thepumping station.Thus,the update in the agricultural irrigation pumping station renovation process,theimprovement strategy and technology is particularly important.Agricultural irrigation pumping station renovation strategy mainly includes the technological transformation,technological transformation,water pump motor and the driving device and the water inlet and outlet pipe,water inlet and outlet flow passage retrofit buildings transformation.Therefore,the effect depends on the effect of pumping station renovation in the technological transformation,technological transformation,water pump motor and the driving device and the water inlet and outlet pipe,water inlet and outlet flow passage retrofitbuildings transformation.This paper briefly introduces the general situation of Changfeng County of Yongfengirrigation pumping station project,the existing main problems for the electrical and mechanical equipment used for a long time,has reached a lifetime,usually operationmaintenance is not standard not overhaul,the pump impeller damaged seriously,sealingthe gap is too large,often need to replace the original water pump bearings,water pipelinedesign is not reasonable,import the water flow is poor,the operation of the water pumpcavitation phenomenon of long time,pump vibration quite powerful,large noise,has beensupporting the motor insulation aging,power distribution cabinet clutch difficult,arc shieldfailure,sometimes generate strong arc,the operator of physical and mental hurt greatly;the main transformer interturn insulation low,poor heat dissipation performance,often withpipeline the phenomenon of crack fried water inlet,Water Leakage,serious seepageproblem,pump damage Water Leakage.First of all,through project planning of the pumping station,determine the import pooldesign water level,draw up lift of pump,the design head H and irrigation flow Q selecting pump type 32SAP-19 J,according to the water pump shaft power and speed selectionmatching motor model for Y4503-10,according to the water pump single flow quantity and the flow velocity in the tube to determine the control pipe diameter;determine the pumpplane size according to the pump unit size,spacing and unitmaintenance requirements,according to the pump height and lifting requirements determine the pump house facadedimensions;according to the inlet and outlet pipe spacing and water inlet and outlet flowrequirements to determine the import pool size.Then transformation of pump station engineering budgetary estimate,and thetransformation of engineering economic analysis,benefit cost calculation of the pumping station renovation engineering,using sensitivity analysis and evaluation of the national economy.Finally,the construction organization design for pumping station renovation engineering,carries on the overall layout of the project,the reasonable arrangement of constructionschedule,construction scheme for main project preparation,and the allocation of resources.Through the research on the design of Yongfeng irrigation pumping station renovation project,the overall layout,equipment selection,advanced design concept,the adoption of new technology,new equipment,improve the pump installation height,to ensure the safety of flood control,reduce the repair,maintenance and management cost,improve the efficiency of the device,reducing the energy consumption.Through the renovation of pumping station design,and irrigation water irrigation can be improved and fully guarantee.Reasonable,visible Yongfeng irrigation pumping stationrenovation project in the technical economic feasibility,to achieve the maximization ofeconomic benefits,ecological benefits and social benefits,and provides valuable reference for the pumping station renovation.
