Abstract
A two-stage single-suction horizontal centrifugal pump is provided, the utility model relates to a horizontal centrifugal pump in plumbing equipment, the technical problem needed to be solved in the utility model is to provide a centrifugal pump with higher delivery head and smooth performance, the utility model adopts the horizontal centrifugal pump driven by an electric motor, the centrifugal pump consists of a pump body, a pump shaft, as well as impellers, which is characterized in that the pump body is equipped with two impellers arranged with positive and negative directions, a baffle plate is arranged between the two impellers to divide the pump body cavity into a front part and a rear part, the baffle plate center is provided with a water bearing, and the pump chamber export of the first-stage impeller and the pump chamber export of the second-stage impeller are arranged with 180 DEG. The utility model is applied to lifting and delivering fluid.
Description
Technical field:
The utility model relates to plumbing equipment Zhong De Lying formula centrifugal pump.
Background technique
A kind of Lying formula centrifugal pump by driven by motor is arranged in the prior art, and centrifugal pump mainly is made up of the pump housing, pump shaft and impeller.The pump housing is by the two sections Assemblies in front and back, and pump housing leading portion has suction inlet, back segment that end cap is housed, and there is axis hole in end cap central authorities, between axis hole and the pump shaft mechanical seal are arranged, and pump housing inner chamber is like the volute chamber shape, and outlet is arranged at pump housing top; Pump shaft is a multidiameter shaft, adopts shaft coupling to be connected with motor shaft, and impeller is contained in the pump shaft front portion, and compresses at the terminal loading nut of pump shaft, and impeller also can directly be contained in the motor output shaft end.During the centrifugal pump running, flow of liquid has absorbed the impeller energy delivered through pump chamber, has improved hydraulic pressure, can be used for promoting and carrying liquid.
The model utility content
The utility model technical issues that need to address provide that a kind of lift is higher, centrifugal pump stably turns round.
The technical solution of the utility model adopts driven by motor De Lying formula centrifugal pump, centrifugal pump is made up of the pump housing, pump shaft and impeller, it is characterized in that being provided with in the pump housing two impellers that become forward and reverse layout, there is dividing plate that pump housing inner chamber is divided into former and later two parts between two impellers, there is submerged bearing in dividing plate central authorities, and the pump chamber outlet of first order impeller becomes 180 ° of layouts with the pump chamber exit position of second level impeller.
The utility model is owing to be provided with two impellers, can significantly improve lift, two impellers become forward and reverse layout can eliminate axial force, the pump chamber outlet of first order impeller becomes 180 ° of layouts can eliminate radial force with the pump chamber exit position of second level impeller, and dividing plate central authorities have submerged bearing to help to move steadily, reduce the technique effect that leaks.
Description of drawings
Fig. 1 represents the utility model schematic representation of adopting shaft coupling to be connected with motor output shaft;
Fig. 2 represents impeller and the direct-connected structural representation of motor output shaft;
Fig. 3 represents that the pump chamber of the utility model first order impeller exports the schematic representation that exports into 180 ° of layouts with the pump chamber of second level impeller.
Embodiment
Implement concrete mode of the present utility model below in conjunction with description of drawings: what accompanying drawing 1 was represented is that motor 1 drives De Lying formula centrifugal pump, centrifugal pump mainly is made up of the pump housing 2, pump shaft 3 and impeller 4,5, pump housing leading portion 13 is established suction inlet 6, back segment 15 dress end caps, pump housing top sets out mouth 9, and pump housing inner chamber is like the scroll casing shape chamber; When pump shaft is connected with motor output shaft by shaft coupling, end cap 7 has the support that is connected with the motor land, accompanying drawing 2 is illustrated in motor output shaft when directly installing impeller, end cap is made land 17 and is connected with the land of motor, and axis hole on the end cap 7 of belt supporting frame or the axis hole on the land end cap 17 are all installed mechanical sealing element 8; Pump shaft 3 is multidiameter shafts, adopts shaft coupling 10 to be connected with motor shaft 11, and impeller 4,5 is contained in pump shaft 3 front portions, and compresses at the terminal loading nut of pump shaft; Two impellers 4,5 one-tenth forward and reverse layouts are established dividing plate 12 in the pump housing between two impellers, between the section pump housing junction plane, pump housing inner chamber are divided into former and later two parts before and after dividing plate 12 peripheries are contained in, and dividing plate 12 central authorities establish submerged bearing 14 (seeing accompanying drawing 2); The pump chamber outlet 16 of accompanying drawing 3 expression first order impellers exports 18 positions on the pump chamber bottom and the pump chamber top of second level impeller and becomes 180 ° of layouts.
