Abstract
The invention discloses a centrifugal pump. A pump shaft is arranged in a pump body, and is provided with an impeller; and the pump body at the front end of the impeller is provided with a suction chamber corresponding to the suction inlet of the impeller. The centrifugal pump is mainly structurally characterized in that: the inner wall of the suction chamber is provided with a separation blade. The inner wall of the suction chamber is provided with the separation blade which can be used for preventing a liquid from rotating in the suction chamber, so that the impeller is prevented from driving the liquid at an inlet to generate vortexes, the liquid is prevented from generating the vortexes easily at the inlet, and the centrifugal pump has a small hump on a head curve and runs stably.
Description
Technical field
The present invention relates to liquid pump, is a kind of centrifugal pump specifically.
Background technique
We know, existing centrifugal pump is in the pump housing, to be provided with pump shaft; Pump shaft is provided with impeller, the corresponding suction chamber that is provided with suction eye on the pump housing of impeller front end, and suction chamber is cylindrical; This centrifugal pump because suction chamber is smooth cylindrical, during centrifugal pump work under the drive of impeller; Liquid is easy to generate whirlpool in inlet, and the hump of centrifugal pump lift curve is big, the centrifugal pump fluctuation of service.
Summary of the invention
The technical problem that the present invention solves is; Solve liquid and be easy to generate whirlpool in inlet; The hump of centrifugal pump lift curve is big, and the problem of centrifugal pump fluctuation of service provides a kind of liquid to be not easy to produce whirlpool in inlet; The hump of centrifugal pump lift curve is little, the little centrifugal pump of lift hump that centrifugal pump is stable.
Technological scheme of the present invention is, a kind of centrifugal pump is provided with pump shaft in the pump housing, and pump shaft is provided with impeller, the corresponding suction chamber that is provided with suction eye on the pump housing of impeller front end, and the main structure characteristics are that the inwall of suction chamber is provided with catch.
The inwall of suction chamber of the present invention is provided with two catch.
The invention has the beneficial effects as follows that because the inwall of suction chamber is provided with catch, catch can rotate at suction chamber internal resistance solution stopping body.Prevent that impeller from driving the liquid generation whirlpool of inlet, liquid is not easy to produce whirlpool in inlet, and the hump of centrifugal pump lift curve is little, and centrifugal pump is stable.
Description of drawings
Fig. 1, Fig. 2 are a kind of structural representations of the present invention, also are a kind of embodiment's schematic representation, and Fig. 2 is the left view of suction chamber among Fig. 1.
Embodiment
Like Fig. 1, centrifugal pump shown in Figure 2, be provided with pump shaft 3 in the pump housing 4, pump shaft 3 is provided with impeller 5; The corresponding suction chamber 2 that is provided with suction eye on the pump housing 4 of impeller 5 front ends, the inwall of suction chamber 2 is provided with catch 1, and catch 1 can rotate at suction chamber 2 internal resistance solution stopping bodies; Prevent that impeller 5 from driving the liquid generation whirlpool of inlet; Liquid is not easy to produce whirlpool in inlet, and the hump of centrifugal pump lift curve is little, and centrifugal pump is stable.The inwall that from Fig. 1, Fig. 2, can find out suction chamber 2 is provided with two catch, stops the effective of liquid in rotation.
Claims (2)
1. a centrifugal pump is provided with pump shaft in the pump housing, and pump shaft is provided with impeller, and the corresponding suction chamber that is provided with suction eye is characterized in that the inwall of suction chamber is provided with catch on the pump housing of impeller front end.
2. centrifugal pump according to claim 1 is characterized in that, said suction chamber inwall is provided with two catch.
