Description

Technical Field

[0001] The utility model relates to the technical field of centrifugal pumps, in particular to an adjustment bracket for a chemical centrifugal pump. Background Art

[0002] A chemical centrifugal pump refers to a centrifugal pump used in the chemical industry. Compared with other types of pumps, a chemical centrifugal pump has the advantages of simple structure, low wear resistance, smooth operation, low noise, uniform water discharge, convenient adjustment, and high efficiency. The working principle of a chemical centrifugal pump is that when the pump is filled with water, the impeller rotates to generate centrifugal force. Under the action of centrifugal force, the water in the impeller groove is thrown to the periphery and flows into the pump casing. As a result, the pressure at the center of the impeller decreases, and this pressure is lower than the pressure in the water inlet pipe. Under the action of this pressure difference, water flows from the suction tank into the impeller.

[0003] In view of the above-mentioned and existing related technologies, the inventors believe that the following defects often exist: when using a chemical centrifugal pump, it is generally necessary to install the centrifugal pump on a pad. The traditional pad and centrifugal pump are fixed by bolts during installation. When the specifications of the centrifugal pumps used are different, the centrifugal pump may be inconvenient to install. Therefore, in view of the above problems, an adjustment bracket for a chemical centrifugal pump is proposed. Utility Model Content
