Technical Field

[0001] The utility model relates to the technical field of single-stage pumps, in particular to a single-stage pump sheet metal chassis with a lifting function. Background Art

[0002] The structure of a single-stage centrifugal pump includes a pump body, a pump cover, an electric motor, an impeller, a mechanical seal and other components. Its working principle is to use the electric motor to drive the impeller to rotate, generating centrifugal force to transport the liquid from the suction end to the discharge end. The single-stage screw pump relies on the engagement of the screw and the bushing to produce volume changes to transport the liquid. It is suitable for occasions that require precise flow control.

[0003] Some existing technologies directly use slings to tie the single-stage pump to the outside for lifting. However, directly tying the single-stage pump cannot ensure the stability of the single-stage pump during lifting. Since the single-stage pump has a certain weight, it may cause the single-stage pump to fall off the sling during the lifting process, causing the single-stage pump to fall to the ground, which is not only dangerous but also may cause damage to the single-stage pump.

[0004] A single-stage pump sheet metal chassis with a lifting function is proposed to solve the above problems. Utility Model Content
