Abstract
A horizontal contra multi-stage centrifugal pump belonging to non-modulation type centrifugal pump comprises a pump body with a water inlet and a water outlet, blades pack, wherein the pump is equipped with an upper pump and a lower pump along the horizontal axis, a pressurized water room in pump adopting contra structure. With the above improvements, the utility model combines the aforementioned two pumps optimally and it is provided with the advantages of strong universality, diverse usages, and is liable to maintain.
Description
Technical field
The utility model belongs to the non variable capacitance type centrifugal pump, specifically is that a kind of horizontal stator formula is driven centrifugal pump in multistage.
Background technique
Multistage middle open type centrifugal pump and horizontal single suction multistage centrifugal pump are the pump types of using always, purposes that it is had nothing in common with each other and advantage, but also because structural feature separately, all caused pump being difficult to when safeguarding to install, dismantle, the pipelines that first dismounting successively connects with pump as need etc., or the dismounting of earlier that the bearing unit on the pump housing is axial coupling member carry out the dismounting of bearing unit again, increase the maintenance difficulties of these two kinds of pumps greatly, caused certain harmful effect for the ordinary production of applying unit.
The model utility content
The purpose of this utility model is to overcome above-mentioned deficiency of the prior art, the advantage of above-mentioned two kinds of pumps is optimized combination, thereby is combined as a kind of highly versatile of brand new, and the purposes variation is driven centrifugal pump during the horizontal stator formula that is easy to safeguard is multistage.
For achieving the above object, the utility model is achieved through the following technical solutions:
Be that a kind of horizontal stator formula is driven centrifugal pump in multistage, comprise the pump housing that is processed with entery and delivery port, and with the impeller assembly of pump housing coupling, it is characterized in that the pump housing is divided into upper pump casing, lower pump body two-part down along horizontal axis, the pumping chamber of the pump housing adopts stator formula structure.
Described impeller assembly, stator and pump shaft are cascaded, and when assembling like this, by upper pump casing, lower pump body with its spiral-lock inside, with bolt upper pump casing, lower pump body are fastened as one again.
Entery and delivery port on the described pump housing all is positioned on the following lower pump body of axis, and is positioned at the both sides of lower pump body, when the maintenance pump, only need open upper pump casing and get final product like this.For reducing production costs, be convenient to Foundry Production in enormous quantities in addition, entery and delivery port and lower pump body are integral structure.
The outer installment string water pipe of described upper pump casing, when overhauling, the string water pipe just can be pulled down with upper pump casing like this, has avoided traditional pump to need the deficiency of dismounting string water pipe earlier, makes pump structure more succinct, compact.
The utility model owing to the advantage with above-mentioned two kinds of pumps is optimized combination, thereby has highly versatile, purposes variation, the advantage that is easy to safeguard after above improvement.
Description of drawings
Below in conjunction with accompanying drawing the utility model is described in further detail.
Fig. 1: the utility model cross-sectional view.
1 string water pipe, 2 upper pump casings, 3 pump shafts, 4 lower pump bodies, 5 impeller assemblies, 6 stators.
Embodiment
As shown in Figure 1, drive centrifugal pump during this horizontal stator formula is multistage, comprise the pump housing that is processed with entery and delivery port, and with the impeller assembly 5 of pump housing coupling, it is characterized in that the pump housing is divided into upper pump casing 2, lower pump body 4 two-part along horizontal axis, the pumping chamber of the pump housing adopts stator 6 formula structures.
Described impeller assembly 5, stator 6 and pump shaft 3 are cascaded, and when assembling like this, by upper pump casing 2, lower pump body 4 with its spiral-lock inside, with bolt upper pump casing 2, lower pump body 4 are fastened as one again.
Entery and delivery port on the described pump housing all is positioned on the following lower pump body 4 of axis, and is positioned at the both sides of lower pump body 4, when the maintenance pump, only need open upper pump casing 2 and get final product like this.For reducing production costs, be convenient to Foundry Production in enormous quantities in addition, entery and delivery port and lower pump body 4 are integral structure.
The outer installment string water pipe 1 of described upper pump casing 2, when overhauling, string water pipe 1 just can be pulled down with upper pump casing like this, has avoided traditional pump to need the deficiency of dismounting string water pipe 1 earlier, makes pump structure more succinct, compact.
The utility model owing to the advantage with above-mentioned two kinds of pumps is optimized combination, thereby has highly versatile, purposes variation, the advantage that is easy to safeguard after above improvement.
Claims (5)
