Structural principle of horizontal slurry pump

Structural principle of horizontal slurry pump


The slurry pump can be divided into single-stage/multi-stage, single-suction/double-suction, cantilever horizontal/vertical according to different principles.

The horizontal slurry pump is a kind of centrifugal pump from the physics principle, and conceptually refers to a kind of machinery that increases the energy of the solid-liquid mixed medium by the action of centrifugal force (the rotation of the impeller of the pump). A device that converts into the kinetic and potential energy of a medium. The name of a horizontal slurry pump is a centrifugal pump that is divided from the perspective of the transport medium. In addition, horizontal slurry pumps can be divided into different types from different angles:

The horizontal slurry pump and the open/vertical combination of the pump casing horizontally, the basic structure consists of the impeller, the pump casing, the pump shaft, the bearing and the bracket, and the power also includes the electric motor, the opposite wheel or the belt wheel coupling, etc. The wear parts further include a lining bushing, etc., the seal comprises a shaft seal, a secondary impeller, etc., the support comprises a bracket, etc., but the internal principle is uniform. When the impeller rotates rapidly, the blade causes the medium to rotate rapidly, rotating The medium flies out of the impeller under the action of centrifugal force. After the medium in the pump is thrown, the central part of the impeller forms a vacuum area, and the medium is pressed into the feeding tube through the pipe network under the action of atmospheric pressure (or water pressure). In this way, continuous feeding can be achieved to achieve the head and flow required by the process design. Of course, the feeding mode is currently more indented, that is, the material level is higher than the feeding pipe, the step of pouring water from the upper water pipe or the pump casing to the inside can be subtracted.

The horizontal slurry pump is a kind of centrifugal pump which has evolved in recent years due to the large material transporting particles and has relatively high efficiency and relatively strong performance. It is currently one of the indispensable equipments in the various processes of the coal preparation plant.
