Description

Technical Field

[0001] The utility model relates to the technical field of assembly workbenches, in particular to an assembly workbench for an oil-gas mixed transmission pump. Background Art

[0002] The single-screw pump, used in oil-gas mixed transmission pumps, is a reliable and simple eccentric rotor positive displacement pump. The pump's main components are a rigid rotor with a single-start helical screw and a stator, typically made of an elastic material and featuring a double-start helical hole. The rotor rotates within the stator. Because the stator lead is twice the rotor pitch, a series of enclosed cavities with a phase angle of 180° are formed. These cavities continuously move from the pump's suction port 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] During assembly, the reducer needs to be installed on the rear side of the pump body. The traditional installation method is to manually lift the reducer so that the connecting flange hole of the reducer is aligned with the connecting flange hole on the fixed part of the pump body, and then tighten the bolts and nuts. However, manual lifting is affected by the weight of the reducer, the assembly is unsafe, and the alignment efficiency is low, which seriously affects the assembly efficiency. Utility Model Content
