Work Detail

Mechanical Engineering Installation Works - Refurbishment Of Snail Pumping Plants. Disassembly And Assembly Of Two Snail Pumping Plants The Lip Association Is The Operator Of The Dortmund-Scharnhorst Sewage Treatment Plant, On Which Various Reinvestment Measures Are Carried Out In The Area Of ​​Wastewater And Mud Treatment Due To Age. The Services Described Here Include The Renovation Of The Snail Pumping Station Of The Filter System And The Snail Pumping Station To Promote The Return Sludge. On The Sewage Treatment Plant Dortmund-Scharnhorst, The Cleaned Waste Water From The Expiry Of The Clarification Basins Is Lifted Into The Filtration System With An Output Of 955 L/S And A Diameter Of 1,750 Mm Into The Filtration System And From There In The Free Slope. Both The Pumps And The Concrete Troughs Of The Filter Lift Were Built In 1995 And Must Be Immediately Overhauled Due To Progressive Wear And Tear. In Order To Ensure Reliable Transportability Of The Entire Feed Water In The Filter Lift, The Following Repair Measures Are Required: - Barrier Of The Snail Clot Via Existing Dam Tablets, Cleaning And Draining Of The Pump Sump In The Influx Area Of ​​The Snail. - Disassembly And Disposal Of A Conveyor Snail Including The Guide Sheets And The Sub -Bearing. - Disassembly Of The Upper Bearing And The System Components Required For The Renovation Of The Upper Bearing Via Existing Ceiling Crane Tracks Including Disconnecting The Engine. - Beating The Superficial Concrete Layer Of The Trough Including Foot Bearing Foundation With A Depth Of Approx. 10 Cm. Disposal Of The Clipped Material And Cleaning Work. - Overhaul / Renewal Of The Upper Bearing Including Removal / Transport And Re -Installation As Well As The Set Of New Wear Parts Such As Seals And First Fat Filling - Renewal Of The Warehouse Shaft And Flange Connection To Match The Existing Upper Bearing And New Snail - Installation Of The New Snail Bodies Including Corrosion Protection And Sub -Bearing - Concrete Trough New Insert And Restore The Foot Bearing Foundation Including Preparatory Cleaning Measures - Assembly Of The Guidelines Including Connecting Parts - Commissioning Of The New Snail With 14 -Day Trial Run. Only After Successful Test Run Can Be Renovated The Second And Final Snail According To The Pattern Described Above. The Drive Unit Of The Snail Pumps Are Preserved. The Concrete Troughs Are Renewed Superficially, A Comprehensive Concrete Renovation Is Not Necessary. To Carry Out The Disassembly And Assembly Work, The Use Of A Car Crane With A Range Of Approx. 30 Meters Is Required. The Intended Car Crane Parking Space Is Located On The Access Road North Of The Snail Pumping Station, Which Is Why The Road Has To Be Cordoned Off. Sneck Pumping Unit Return Sludge: In Addition, The Return Sludge In The Return Sludge Pump Is Used As Part Of The Biological Cleaning Stage Via Three Snail Pumps With A Förd
