The model utility content
The purpose of the utility model is exactly the above-mentioned deficiency that exists to existing low lift pumping plant, ultralow lift pumping plant; A kind of preceding shaft extension formula pumping plant of hydrocone type water outlet is provided; This pumping plant can guarantee that water pump has good water inlet condition, is convenient to unit and installs and overhaul, and reduces the interrupter device investment; Make things convenient for unit operation, administer and maintain, improve the pumping station operation Security.
The purpose of the utility model patent is to realize like this; The preceding shaft extension formula pumping plant of hydrocone type water outlet; Comprise shaft extension formula water pump assembly and siphon outlet conduit, said shaft extension formula water pump assembly comprises blade wheel chamber, diffuser, water pump spindle, transmission device, power engine and packing seal, it is characterized in that; Be provided with the ogee water inlet flow channel; Blade wheel chamber and diffuser are installed between ogee water inlet flow channel and the siphon outlet conduit, and power engine and transmission device are installed in the top of ogee water inlet flow channel, and water pump spindle passes packing seal from the ogee water inlet flow channel and is connected with transmission device.
Said ogee water inlet flow channel is progressively upwarped to the horizontal straight section of outlet by the horizontal straight section of import, and the import and export section of ogee water inlet flow channel progressively carries out the transition to round exit by rectangular inlet, and bulkhead gate is installed in import.
The import and export section of said siphon outlet conduit progressively carries out the transition to the rectangle outlet by circular import, and vacuum breaker valve is installed at the hump top of siphon outlet conduit.
The outlet of said siphon outlet conduit is provided with the cutout gate.
Consider that according to pumping plant water outlet side water level combination, hump height and pumping plant Security needs the outlet of siphon outlet conduit also can be provided with the cutout gate.
The utility model has adopted ogee water inlet flow channel and preceding shaft extension formula water pump assembly, can satisfy the water pump depth of immersion, reduces the pump house cutting depth; Power engine and transmission arrangements are above the ogee water inlet flow channel; The space is spacious, and installation, maintenance and operation management are convenient, and the ventilation and heat condition is good.Siphon outlet conduit cooperates the vacuum breaker valve cutout, and reliable cutout mode is provided, and helps reducing pumping plant investment and interrupter device maintenance cost, is convenient to operation management, has improved the Security of pumping plant operation.The preceding shaft extension formula pumping plant of hydrocone type water outlet is specially adapted to the low lift pumping plant of Hydraulic and Hydro-Power Engineerings such as Inter-Basin Water Transfer Project, water environment treatment engineering, cities and towns water supply and sewage engineering and urban flood defence.
Current get into the ogee water inlet flow channel from water inlet pool through the bulkhead gate hole; Flow into the water pump vane chamber again, the water body that obtains energy is discharged from the diffuser outlet, gets into siphon outlet conduit; Finally discharge, flow to water outlet pool through the stop valve aperture of door from the siphon outlet conduit outlet.When unit orderly closedown or accidental shutdown, vacuum breaker valve is opened automatically, cuts off current; Move exceeding under mouthful the highest operating water level and the ultra historical water level situation like water pump assembly; Can cut off current through closing outlet cutout gate during shutdown, guarantee water pump assembly safety.Before start, shut down in back or the running, the operations staff can safeguard or check power engine, transmission device and water pump, gets into the inspection of vacuum breaking valve chamber or safeguards the vacuum breaking facility.After the shutdown, close the import bulkhead gate, can carry out examination and maintenance water pump.
