Abstract
A vertical type unsealed self-priming oil pump consists of an electric motor, a pump body, a pump cover, an impeller, a pump shaft, an oil inlet pipe and an oil outlet pipe, wherein a cylindrical sealed cavity is arranged inside the pump body from the upper end to the bottom end of the pump body; the pump shaft penetrates into the sealed cavity which consists of an outer cylinder body; the outer cylinder body is provided with an opening ring and a labyrinth channel; the impeller is arranged at the lower end of the pump shaft; the periphery of the impeller is provided with a diffuser which is connected with a clapboard at the underside of the impeller; the opening ring is arranged on the upside of the impeller; the labyrinth channel is arranged above the opening ring and inside the outer cylinder body; the pump shaft is provided with an auxiliary impeller; the upside of the auxiliary impeller is provided with a cover plate which is connected with the pump cover; and the sidewall of the oil inlet pipe is provided with an electronic vacuum breaking valve. The vertical type unsealed self-priming oil pump makes use of the electronic vacuum breaking valve to break shutdown siphonage, thereby ensuring that the pump can be started and shut down frequently; adopting the diffuser as a pumping chamber reduces maintenance cost; adopting the sealed cavity of a labyrinth structure ensures that medium particle is not easy to enter into the sealed cavity; and adopting the auxiliary impeller dynamic seal to replace the prior mechanical seal improves sealing reliability.
Description
Technical field:
The utility model relates to mechanical field, relates in particular to pump, and particularly a kind of vertical nothing sealing is from oil scavenge pump.
Background technique:
The oil plant that is applicable to land oil depot, oil carrier, fuel tank, gas station, harbour, airport from oil scavenge pump is carried, and contains granule and the medium of uniform temperature is arranged from the low level suction.In the prior art, extensively horizontal simple to operate from oil scavenge pump, easy to maintenance, but still exist following shortcoming (1) import to adopt flap valve to make check valve, cause hydraulic loss big, influence self-priming time and self-priming height, and when being not closed completely, medium just because siphon is flow to end, starts pump once more and still needs water in the pump, makes troubles to operation; (2) pumping chamber is the scroll casing type structure, and pump volume is big, in case the spiral case wearing and tearing need integral body to scrap the maintenance expenses height; (3) particle easily enters Seal cage in the medium, and temperature, corrosion influence cause seal failure in addition, need shutdown maintenance, reduce the pump operation reliability.
Summary of the invention:
The purpose of this utility model provides a kind of vertical nothing sealing from oil scavenge pump, described this vertical nothing sealing from oil scavenge pump to solve in the prior art horizontal big from the oil scavenge pump hydraulic loss, the technical problem that siphon, medium easily enter Seal cage takes place to shut down.
This vertical nothing of the present utility model seals from oil scavenge pump by motor, the pump housing, pump cover, impeller, pump shaft, oil inlet pipe and oil outlet tube constitute, wherein, in the described pump housing, from pump housing upper end to being arranged with the cylinder barrel shaped Seal cage, described pump shaft runs through described Seal cage, Seal cage is made of outer cylinder body, described outer cylinder body is provided with choma and labyrinth channel, described impeller is arranged on the lower end of pump shaft, the periphery of impeller is provided with Diffuser, described Diffuser is connected with the dividing plate of impeller downside, described choma is arranged on the upside of impeller, described labyrinth channel is arranged on the top of choma, in the outer cylinder body, top, labyrinth channel sleeve is connected on the pump shaft, pump shaft is provided with pays impeller, pays the impeller upside and is provided with cover plate, and described cover plate is connected with pump cover, the sidewall of described oil inlet pipe is provided with the electronic vacuum destructive valve, and described electronic vacuum destructive valve is communicated with oil inlet pipe.
Further, described Diffuser is connected with described dividing plate by bolt.
Further, the control end of described electronic vacuum destructive valve is connected with the control end of described motor.
Working principle of the present utility model is: the electronic vacuum destructive valve is set in the oil inlet pipe, by controller control electronic vacuum destructive valve and motor, make the closing of electronic vacuum destructive valve, open and the opening, stop synchronously of motor, destroy and shut down siphon, preserve the interior medium of pump and do not run off, make pump can frequently open easily, stop; Adopt Diffuser to replace pumping chamber of scroll casing, simplified structure greatly, but and single-piece change, reduce maintenance cost; Adopt the labyrinth structure Seal cage, media particle is difficult for entering in the Seal cage; Pay the impeller dynamic seal and replace traditional machine envelope or packing seal, improved sealing reliability.
The utility model and prior art contrast, and its effect is actively with tangible.The utility model is arranged at the electronic vacuum destructive valve in the oil inlet pipe of pump, destroys and shuts down siphon, makes pump frequent start-stop easily; Adopt Diffuser as pumping chamber, reduce maintenance cost; Adopt the labyrinth structure Seal cage, media particle is difficult for entering in the Seal cage; Adopt and pay impeller dynamic seal replacement traditional machine envelope or packing seal, improved sealing reliability.
