Description
Technical field
The utility model patent relates to the pump installation structural shape, and especially the structure of submersed three-flow pump installation belongs to the Hydraulic and Hydro-Power Engineering technical field.
Background technology
Submersed three-flow pump is normal forms tubular pump installation with straight pipe type water-in and water-out runner, mainly is made up of intake pool, straight pipe type water inlet flow channel, submersed three-flow pump, straight pipe type outlet passage, stop gate and discharge bay etc.The straight pipe type outlet passage often adopts the stop gate cutout, and technical requirements is high, and maintenance cost is big, and safety and stability that pump installation is moved have significant impact; The straight pipe type outlet passage is if adopt the flap valve cutout, because flap valve can not complete opening in running, causes hydraulic loss, reduces pump installation efficient.
The utility model content
The purpose of the utility model provides a kind of novel submersed three-flow pump installation, for water pump provides good water inlet condition, makes things convenient for the installation maintenance of unit; Be convenient to operational management; Reduce hydraulic loss, improve unit efficiency, improve the safety and the reliability of pumping station operation.
Above-mentioned purpose realizes through following technical scheme: a kind of novel submersed three-flow pump installation; Comprise the intake pool, straight pipe type water inlet flow channel, submersed three-flow pump, siphon outlet conduit, cutout gate and the discharge bay that set gradually connection; It is characterized in that described straight pipe type water inlet flow channel horizontal arrangement; Its admission section is that rectangle progressively carries out the transition to outlet for circular, and round exit links to each other with the admission section of submersed three-flow pump, and import is provided with Emergency Gate; The import of described siphon outlet conduit links to each other with submersed three-flow delivery side of pump section, and its import is that circular vertical cross section progressively carries out the transition to outlet for the rectangle vertical cross section, and the outlet of rectangle vertical cross section links to each other with discharge bay; The top of described siphon outlet conduit is provided with air admission valve.
The top of said straight pipe type water inlet flow channel is provided with the enter hole.
Said cutout gate is arranged on the outlet of siphon outlet conduit.
The utility model science rational in infrastructure is implemented easily, adopts straight horizontal tubular type water inlet flow channel, helps reducing hydraulic loss, can good water inlet condition be provided for water pump, gives full play to the energy characteristics and the cavitation corrosion performance of water pump; Submersed three-flow pump can adopt the integral hoisting structural shape, maintenance is installed conveniently; Adopt the cutout of siphon outlet conduit and air admission valve, reduce interrupter device investment and maintenance cost, cutout is reliable, is convenient to operational management, improves the safety property of pumping station operation.Current get into submersed three-flow pump from intake pool through the straight pipe type water inlet flow channel, discharge from the submersed three-flow delivery side of pump again, get into siphon outlet conduit, flow to discharge bay.When unit orderly closedown or accidental shutdown, air admission valve is opened automatically, destroys vacuum, cuts off current; When water pump assembly is shut down,, guarantee water pump assembly safety through the cutout of cutout gate under superelevation water level situation.Emergency Gate is closed in maintenance and when safeguarding, drain the ponding of straight pipe type water inlet flow channel after, the operations staff can get into from the enter hole, the examination and maintenance submersed three-flow pump is convenient and safe.
