Description

Split pump with novel anti-sedimentation blocking balance pipe structure

Technical Field

The utility model discloses a split pump with a novel anti-sedimentation blocking balance pipe structure, relates to the technical field of fluid machinery, and particularly relates to an anti-sedimentation blocking balance pipe structure applied to split pumps for medium conveying in various industries.

Background

According to the utility model, the balance pipe is arranged on the pump cover, so that the phenomenon that substances in the balance pipe are deposited and blocked after the machine is stopped is avoided.

The technical means adopted by the utility model are as follows:

a split-start pump with a novel anti-settling blocked balance tube structure, comprising: the pump cover and the suction pipe are connected with the inlet of the split pump;

further, a balance pipe is arranged between the pump cover and the suction pipe.

Furthermore, the balance cavity of the pump cover is provided with a through hole and is provided with a connecting flange, the balance cavity is connected with the balance pipe through the connecting flange, the balance pipe is connected with the suction pipe to lead to the suction cavity of the pump, medium sedimentation during shutdown is avoided to cause blockage of the balance pipe, and the pump has the characteristics of safe and reliable operation, stable operation of the pump, and prolonged continuous operation time and service life of the pump.

Further, the balance pipe is located at the upper part of the split pump.

The medium flows from the balance cavity at the pump cover to the suction pipe through the balance pipe, and cannot be precipitated due to certain flow velocity of the medium. However, when the pump is stopped, the medium sediment can flow from the high point to the pump body part without causing blockage to the balance pipe because the balance pipe is positioned at the upper side position of the pump.

The utility model solves the problems that the pump is easy to precipitate and block the medium of the balance pipe, ensures the operation stability of the pump, ensures the operation of the pump to be safer and more reliable, and prolongs the continuous operation time and the service life.

Compared with the prior art, the utility model has the following advantages:

1. according to the split pump with the novel anti-sedimentation blockage balance pipe structure, the balance pipe is connected between the balance cavity of the pump cover and the suction pipe, a medium is introduced into the suction cavity from the balance cavity through the suction pipe, and blockage of the balance pipe caused by sedimentation of the medium when the pump is stopped is avoided;

2. according to the split pump with the novel anti-sedimentation blockage balance pipe structure, the balance pipe is arranged at the upper part of the pump body, and medium sediments can flow to the position of the pump body from a high point without blocking the balance pipe;

3. the split pump with the novel anti-sedimentation blocking balance pipe structure solves the problems that the pump is easy to sediment and block a medium of the balance pipe, ensures the running stability of the pump, enables the pump to run more safely and reliably, and prolongs the continuous running time and the service life.

In conclusion, the technical scheme of the utility model solves the problems that when the existing split pump in the prior art is used for conveying a medium easy to precipitate, under the condition of shutdown, precipitates block a balance pipe, the pressure of a sealing cavity at a discharge side is increased to cause sealing leakage, axial force cannot be balanced to cause overload operation of a bearing, abrasion of a dynamic ring and a static ring, the service life of the pump is shortened and the like.
