Embodiment Construction
[0037] Referring now to Figure 1, there is shown a screw pump 1 made in accordance with the invention comprising an outer cylindrical housing 2 having an inlet end 1a and a discharge end 1b.
[0038] The threaded rotor 3 is a molded or welded component that is directly connected to the motor 4 and is rotatably mounted inside said outer casing 2 .
[0039]The threads 5 extending on the threaded rotor 3 are broken at pitch intervals to form as many thread portions 5 as there are pitches. The threaded shaft 6 is not broken, and as a result, when the rotor 3 rotates, a plurality of annular spaces are formed between said broken threaded portions 5 .
[0040] A plurality of annular restraints 7 fitted in said annular space are inserted therein. When the screw rotor 3 rotates, said means 7 restrain the conveyed fluid from moving in a direction around the axis 6 and force the fluid to move axially towards the discharge end 1b. An annular restraint 7 is arranged at the beginning of t...
