Abstract
The invention relates to a novel strong self-absorption double-suction pump which comprises a double-suction pump and is characterized in that a pump shaft arranged on the double-suction pump is connected with a vacuum pumping device through an electromagnetic gear; and the vacuum pumping device is connected with two pump cavities of the double-suction pump through a pipeline. The novel strong self-absorption double-suction pump is characterized in that the vacuum pumping device consists of a vacuum pump body, a mechanical seal, a vacuum runner, a vacuum equally-dividing device, a transmission shaft, a vacuum distributor and a vacuum pump cover; one end of the transmission shaft is connected with the electromagnetic gear; the transmission shaft extends in the vacuum pump body; the transmission shaft is connected with the mechanical seal and the vacuum runner; one end of the vacuum pump body is connected with the vacuum equally-dividing device; the vacuum pump cover is installed outside the vacuum distributor; the vacuum distributor is connected with the vacuum equally-dividing device; and the vacuum equally-dividing device is connected with the two pump cavities arranged on the double-suction pump through the pipeline. The novel strong self-absorption double-suction pump has the advantages that the use function of the double-suction pump is improved, the cost of a whole unit is reduced, and the floor space of the whole unit is decreased.
Description
Technical field
The present invention relates to a kind of novel strong self-priming double suction pump.
Background technique
Existing double suction pump is mainly formed (seeing accompanying drawing one) by bearing support 11, rolling bearing 12, machine sealed cover 13, mechanical seal 14, axle 15, impeller 16, the pump housing 17, pump cover 18, seal 19, bearing gland 20 etc.Because the function that existing double suction pump self does not vacuumize.There is following shortcoming in it: is installed in liquid level when above when the user needs horizontal type multi-stage pump, need joins a vacuum pump in addition, vacuumize diversion earlier, and after treating to be full of water in the double suction pump, starting double suction pump, vacuum pump out of service.Cause whole unit cost high, floor space is big.
Summary of the invention
The objective of the invention is to solve double suction pump self in the existing technology and do not vacuumize that function is existing to be installed in the problem that liquid level need be joined a vacuum pump when above in addition when double suction pump; Improve the function of use of double suction pump; Make one of which platform double suction pump have the function of two pumps; Promptly both had the function of vacuum pump, had the function of double suction pump again.The present invention designs a kind of novel strong self-priming double suction pump, comprises double suction pump, it is characterized in that: on the pump shaft of double suction pump, connect a vacuum pumping device by electromagnetic gear, connected two pump chambers of double suction pump on the vacuum pumping device by pipeline.It is characterized in that: vacuum pumping device is made up of vacuum pump body, mechanical seal, vacuum runner, vacuum divider, transmission shaft, vacuum distribution, vacuum pump cover; One end of transmission shaft connects electromagnetic gear; Transmission shaft stretches in the vacuum pump body; Be connected with mechanical seal and vacuum runner on the transmission shaft, an end of vacuum pump body is connected with vacuum distribution, and the vacuum distribution outside is equipped with the vacuum pump cover; Vacuum distribution connects the vacuum divider, and vacuum divider connecting pipeline connects two pump chambers of double suction pump.Advantage of the present invention is to improve the function of use of double suction pump; Reduce whole unit cost, reduce whole unit floor space.
Description of drawings
Fig. 1 is the prior art constructions schematic representation,
Fig. 2 is a structural representation of the present invention,
1 double suction pump, electromagnetic gear 2, vacuum pump body 3, mechanical seal 4, vacuum runner 5, vacuum divider 6, transmission shaft 7, vacuum distribution 8, vacuum pump cover 9, pipeline 10 among Fig. 2.
Below in conjunction with accompanying drawing and construction embodiment the present invention is made detailed operation instruction.
Embodiment
Comprise double suction pump among the figure, it is characterized in that: on the pump shaft of double suction pump, connect a vacuum pumping device, connect two pump chambers of double suction pump on the vacuum pumping device by pipeline by electromagnetic gear.It is characterized in that: vacuum pumping device is made up of vacuum pump body, mechanical seal, vacuum runner, vacuum divider, transmission shaft, vacuum distribution, vacuum pump cover; One end of transmission shaft connects electromagnetic gear; Transmission shaft stretches in the vacuum pump body; Be connected with mechanical seal and vacuum runner on the transmission shaft, an end of vacuum pump body is connected with vacuum distribution, and the vacuum distribution outside is equipped with the vacuum pump cover; Vacuum distribution connects the vacuum divider, and vacuum divider connecting pipeline connects two pump chambers of double suction pump.
The present invention is on existing double suction pump basis; Install a vacuum pumping device additional, this vacuum pumping device is made up of electromagnetic gear 2, vacuum pump body 3, mechanical seal 4, vacuum runner 5, vacuum divider 6, transmission shaft 7, vacuum distribution 8, vacuum pump cover 9 etc.When multistage pump need vacuumize diversion, drive 5 rotations of vacuum runner through electromagnetic gear 2, produce vacuum;, make to produce vacuum in the double suction pump through the gas in two pump chambers of pipeline 10 extraction double suction pumps by vacuum divider 6, suct the pump chamber that water is full of double suction pump; After treating the double suction pump proper functioning, break off through electromagnetic gear 2 again, transmission shaft 7 is stopped operating; Because a pump has the function of two pumps, has both reduced whole unit cost, has reduced whole unit floor space again.
