Description

Technical Field

[0001] The utility model relates to the technical field of sewage delivery pumps, in particular to a sewage delivery pump testing platform. Background Art

[0002] The sewage pump is a sewage treatment equipment. The single screw pump in the sewage pump is a reliable and simple eccentric rotor type positive displacement pump. The main components of the pump are a rigid rotor with a single-head spiral and a stator with double-head spiral holes, which is usually made of elastic material. The rotor rotates in the stator. Since the stator lead is twice the rotor pitch, a series of closed cavities with a phase angle of 180° are formed. They move continuously from the suction port of the pump to the discharge port as the rotor rotates.

[0003] The flow rate of a single-screw pump has nothing to do with the type of conveying medium, but only depends on the size of the closed cavity formed between its stator and rotor. The size of the cavity depends on three factors: rotor cross-sectional diameter, rotor eccentricity and stator lead.

[0004] At present, in the design process of sewage pumps, corresponding tests need to be carried out on them, such as the flow delivery situation within a certain period of time, the working efficiency when used in conjunction with external treatment devices, etc. However, most traditional testing platforms can only perform testing operations on a single model of sewage pumps, which are less practical and inconvenient to use.
