Abstract
The invention relates to a novel strong self-absorption horizontal multistage pump which comprises a pump shaft and an electromagnetic gear in a horizontal multistage pump and is characterized by also comprising a vacuum pump body; the vacuum pump body is internally provided with a transmission shaft, a vacuum runner sleeved on the transmission shaft, a vacuum distributor connected with the outer part of the vacuum pump body and a vacuum equally-dividing device connected with the vacuum distributor; a gas inlet of the vacuum equally-dividing device is communicated with an inner cavity of the horizontal multistage pump; the end part of the transmission shaft passes through the vacuum pump to be connected with one end of the electromagnetic gear; and the other end of the electromagnetic gear is connected with the tail end of the pump shaft in the horizontal multistage pump. The novel strong self-absorption horizontal multistage pump has advantages that the cost is saved, the installation is simple and convenient, the small size of the pump does not occupy space, the stability of a product is improved, and the service life of the product is prolonged.
Description
Technical field
The invention belongs to horizontal type multi-stage pump, particularly a kind of novel horizontal type multi-stage pump with strong self-absorption function.
Background technique
At present, existing horizontal type multi-stage pump is mainly formed (seeing accompanying drawing one) by axle, bearing part, inlet segment, stage casing, stator, water exit end, final stage stator, impeller, tail-hood etc.The function that such structural design causes multistage pump self not vacuumize; In industrial applicability, there is following shortcoming in it: be installed in liquid level when above when the user needs horizontal type multi-stage pump, need join a vacuum pump in addition with auxiliary multistage pump; Promptly earlier vacuumize diversion and advance multistage pump with vacuum pump; After treating to be full of water in the horizontal type multi-stage pump, starting horizontal type multi-stage pump, and vacuum pump out of service.In the mounting arrangements process of equipment integral, on the basis of multistage pump, also will consider the means of fixation and the putting position of vacuum pump, and this usage mode takies volume, very inconvenience more.
Summary of the invention
The object of the invention is to overcome the deficiency of existing technology, has proposed a kind of novel strong self-priming horizontal type multi-stage pump.
The present invention is achieved in that a kind of novel strong self-priming horizontal type multi-stage pump; Comprise: pump shaft, electromagnetic gear in the horizontal type multi-stage pump; It is characterized in that: also comprise a vacuum pump body; This vacuum pump body inside is provided with transmission shaft, is set in the vacuum runner on the transmission shaft, and the outside vacuum distribution and the vacuum divider that is connected with vacuum distribution that connects of this vacuum pump body, the suction port of this vacuum divider connect with the inner chamber of multistage pump and be connected; The end of transmission shaft is passed vacuum pump body and is connected with an end of said electromagnetic gear, and the tail end of the pump shaft in the other end of this electromagnetic gear and the horizontal type multi-stage pump is connected.
Said vacuum distribution has 3 rooms.
Advantage of the present invention: practice thrift cost, install very simple and conveniently, do not account for volume, and improved the stability of product, prolong its working life.
Description of drawings
Fig. 1 is the prior art constructions schematic representation.
Fig. 2 is a structural representation of the present invention.
Below in conjunction with accompanying drawing and embodiment the present invention is elaborated.
Embodiment
Among the figure; A kind of novel strong self-priming horizontal type multi-stage pump; Comprise: pump shaft 2, electromagnetic gear 3 in the horizontal type multi-stage pump 1, it is characterized in that: also comprise a vacuum pump body 4, this vacuum pump body inside is provided with transmission shaft 5, is set in the vacuum runner 6 on the transmission shaft; The outside vacuum distribution 7 and the vacuum divider 8 that is connected with vacuum distribution that connects of this vacuum pump body; The suction port 9 of this vacuum divider and the inner chamber of multistage pump 10 connects and is connected, and the end of transmission shaft is passed vacuum pump body and is connected with an end of said electromagnetic gear, and the tail end of the pump shaft that the other end of this electromagnetic gear and horizontal type multi-stage pump are interior is connected.
Said vacuum distribution has 3 rooms.
When multistage pump need vacuumize diversion, drive 6 rotations of vacuum runner through electromagnetic gear 2, produce vacuum; By the gas in the vacuum divider 8 extraction horizontal type multi-stage pumps; Make to produce vacuum in the horizontal type multi-stage pump, suct water and be full of horizontal type multi-stage pump, treat the horizontal type multi-stage pump proper functioning after; Break off vacuum runner 6 through electromagnetic gear 2 again, vacuum runner 6 is quit work.
Below only expressed mode of execution of the present invention, it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the patent of invention scope.Should be pointed out that for the person of ordinary skill of the art under the prerequisite that does not break away from the present invention's design, can also make some distortion and improvement, these all belong to protection scope of the present invention.Therefore, the protection domain of patent of the present invention should be as the criterion with accompanying claims.
Advantage of the present invention is: simple in structure, installation was both simple, convenient, saved man-hour again, and had improved the stability of product, prolonged its working life.
Claims (2)
1. novel strong self-priming horizontal type multi-stage pump; Comprise: pump shaft, electromagnetic gear in the horizontal type multi-stage pump; It is characterized in that: also comprise a vacuum pump body; This vacuum pump body inside is provided with transmission shaft, is set in the vacuum runner on the transmission shaft, and the outside vacuum distribution and the vacuum divider that is connected with vacuum distribution that connects of this vacuum pump body, the suction port of this vacuum divider connect with the inner chamber of multistage pump and be connected; The end of transmission shaft is passed vacuum pump body and is connected with an end of said electromagnetic gear, and the tail end of the pump shaft in the other end of this electromagnetic gear and the horizontal type multi-stage pump is connected.
