The World's Highest Speed! Changlongshan Ultra-high Head Section Pumped-storage Unit Completes Test

     On November 14, Good News Came From Zhejiang Changlongshan Pumped Storage Power Station, The Birthplace Of The "two Mountains Concept". Unit 5 Of The Power Station Successfully Completed The Volute Hydraulic Test With A Pressure Value Of 17.597 Mpa And A Pressure Hold Time Of 30 Minutes. , rtd temperature sensor and cable manufacturer The Monitoring Results Of Each Part Meet The Design And Specification Requirements, And The Test Is Successful. The 700-meter Ultra-high Head Section Of The World's Highest Speed Water Pump Turbine Volute Passed The Acceptance Work At One Time, Which Is An Important Milestone In The Construction Of Changlongshan Power Station.

Maximum Pressure Of Hydraulic Test Shenzhen Testeck Technology Co., Ltd.

      A Total Of 6 Reversible Hydro-generator Units Are Arranged In The Power Station, Of Which Unit 5 And Unit 6 Are Designed And Manufactured By Shanghai Voith. The Unit Has A Rated Head Of 710 Meters, A Rated Speed Of 600 Revolutions Per Minute, And A Single Unit Capacity Of 350 Mw. It Is The World's First Comprehensive Difficulty Factor For Design And Development.

                             
      The Volute Hydraulic Test Is The "big Test" That The Unit Must Pass In The Installation Stage Of The Embedded Parts. Its Purpose Is To Conduct A Comprehensive Examination Of The Design, Manufacturing And Installation Of The Volute, While Eliminating Welding Residual Stress To Ensure That The Overall Quality Of The Volute Meets The Long-term Safety Of The Unit. Stable Operation Requirements. The Total Duration Of This Hydraulic Test Is About 10 Hours. After Multiple Steps Such As Gradual Pressurization And Pressure Maintaining, The Highest Test Pressure Value Is As High As 17.597 Mpa,Professional rtd temperature sensor manufacturer Which Is Equivalent To The Pressure Value Generated By 1800 Meters Of Water Column, And It Is Maintained At This Pressure For 30 Hours. Minute.

      The Volute Water Pressure Test Was Successfully Completed, Marking The Completion Of The Installation Of The Embedded Parts Of Unit 5, And The Subsequent Stage Of Continuous Concrete Pouring Will Be Transferred. The Unit Plans To Start The Installation Of The Main Equipment In Early 2021, And Complete The Installation And Commissioning And Put It Into Operation In The First Half Of 2022.
