Abstract
A single stage single suction centrifugal pump that belongs to non-positive-displacement type centrifugal pump which comprises a pump shell with a water inlet and a water outlet and bearing assembly which is matched with rotation axis in the pump shell, wherein the pump shell is of single stage single suction cochlear structure which is provided into an upper pump and a lower pump, the bearing assembly is arranged between the pump shell and a coupling. With the optimizing combination of the above two pumps ,the utility model not only remains the advantages of other pumps but also strengthens the universality with diverse usages and liable to maintain.
Description
Technical field
The utility model belongs to the non variable capacitance type centrifugal pump, specifically is a kind of one step single sucking middle open type centrifugal pump.
Background technique
One step single sucking horizontal centrifugal pump and single step dual-sucking level middle open type 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 pipeline that first dismounting successively connects with pump as need etc., or earlier that the bearing unit on the pump housing is axial coupling member dismounting, 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 Production of bearing 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, purposes variation, the one step single sucking middle open type centrifugal pump that is easy to safeguard.
For achieving the above object, the utility model is achieved through the following technical solutions:
It is a kind of one step single sucking middle open type centrifugal pump, comprise the pump case that is processed with entery and delivery port, and with the bearing unit of pump case internal lobe wheel shaft coupling, it is characterized in that pump case is an one step single sucking scroll casing shape structure, be divided into upper and lower two pump housings along horizontal axis, bearing unit is between pump case and coupling.
Safeguard that for pump being easy on the whole bearing unit is also for to be divided into upper and lower two-part middle open type structure along horizontal axis, when safeguarding, the end cover that only need open bearing unit up and down gets final product, and needn't axially carry out the dismounting of each component like this.
In addition, entery and delivery port on the pump case all is positioned on the following lower pump body of axis, and is symmetrical arranged in horizontal direction, has promptly made things convenient for the installation of junction line, and when dismounting also needn't be again the pipeline that links of dismounting earlier and pump case respectively, get final product and the clamping bolt of both points of attachment unclamped.
Be the imbedibility of raising pump, and realize that the oneself of pump self center of gravity adjusts, pump case adopts annular suction chamber.
After the utility model is optimized combination to two kinds of pumps of above-mentioned prior art, not only keeps and inherited the advantage of each pump, and strengthened the versatility of pump, make the purposes variation of pump, and be easier to safeguard.
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.
The A of Fig. 2: Fig. 1 is to the example structure schematic representation.
Among the figure: 1 lower pump body, 2 upper pump casings, 3 impellers, 4 rotatingshafts, 5 coupling, 6 bearing uniies, 7 water intakes, 8 water outlets.
Embodiment
As shown in Figure 1, this one step single sucking middle open type centrifugal pump, comprise the pump case that is processed with entery and delivery port, and with pump case in the bearing unit of impeller 3 rotatingshafts 4 coupling, it is characterized in that pump case is an one step single sucking scroll casing shape structure, be divided into upper and lower two pump housings 2,1 along horizontal axis, bearing unit 6 is between pump case and coupling 5.
Safeguard that for pump being easy on the whole bearing unit 6 is also for to be divided into upper and lower two-part middle open type structure along horizontal axis, when safeguarding, the end cover that only need open bearing unit up and down gets final product, and needn't axially carry out the dismounting of each component like this.
In addition, as shown in Figure 2, entery and delivery port 7,8 on the pump case all is positioned on the following lower pump body 1 of axis, and be symmetrical arranged in horizontal direction, promptly made things convenient for the installation of junction line, and when dismounting also needn't be again the pipeline that links of dismounting earlier and pump case respectively, get final product and the clamping bolt of both points of attachment unclamped.
Be the imbedibility of raising pump, and realize that the oneself of pump self center of gravity adjusts, pump case adopts annular suction chamber.
After the utility model is optimized combination to two kinds of pumps of above-mentioned prior art, not only keeps and inherited the advantage of each pump, and strengthened the versatility of pump, make the purposes variation of pump, and be easier to safeguard.
