Benefits of technology

"The present invention provides a screw pump with an anti-turbulent structure. This structure includes a housing, at least two screw rotors, and a partition. The partition has at least two circular walls and an annular protrusion on the inner surface of the housing. The partition can also be a panel with mounting holes around the rotors. This structure prevents fluids from flowing in opposite directions and becoming turbulent, which improves the efficiency of the screw pump."

Problems solved by technology

Thus, pressures of the fluids are reduced and pressurizing efficiency of the conventional screw pump (50) is low and cannot be efficiently raised.

Embodiment Construction

[0016]With reference to FIGS. 1 to 3, a screw pump with an anti-turbulent structure in accordance with the present invention comprises a housing (10), at least two screw rotors (20) and a partition (30A, 30B).

[0017]The housing (10) is substantially cylindrical and has a mounting tube (11), an inlet (12) and an outlet (13). The mounting tube (11) is axially formed on an inner surface of the housing (10) and has an annular recess (111). The annular recess (111) is formed in and around an inner wall of the mounting tube (11). The inlet (12) is formed in and communicates with the housing (10). The outlet (13) is formed in and communicates with the housing (10), may be formed in the housing (10) and the mounting tube (11), may be communicates with the mounting tube (11) and may correspond to the annular recess (111) of mounting tube (11).

[0018]The at least two screw rotors (20) are axially and parallelly mounted rotatably through the housing (10) and may be mounted through the mounting t...

Abstract

A screw pump with anti-turbulent structure has a housing, at least two screw rotors parallelly mounted through the housing and engaging with each other, and a partition disposed around the at least two screw rotor. The partition may have at least two circular walls respectively formed around the rotors and an annular protrusion formed on an inner surface of the housing and being adjacent to and kept from contacting the at least two circular walls, and may be a panel having at least two mounting holes respectively mounted around the rotors. Fluids flowing in opposite directions are divided by the partition and do not encounter each other and do not become turbulent. Consequently, pressurizing efficiency of the screw pump is improved.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]The present invention relates to a screw pump, especially to a screw pump with an anti-turbulent structure to prevent pressurized fluid from becoming turbulent.[0003]2. Description of the Prior Art(s) A pump transfers mechanical work to fluids, such as liquids or gases, to change states (ex: height, pressure . . . etc.) of the fluid to move the fluids.[0004]With reference to FIG. 5, a conventional screw pump (50) comprises a housing (51) having an inlet (511) and an outlet (512), and two screw rotors (52) axially and parallelly mounted rotatably through the housing (51). Each screw rotor (52) has two threaded parts (521) respectively engaging the threaded parts (521) of the other screw rotor (52). Thus, when one of the screw rotor (52) is rotated, the other screw rotor (52) rotates simultaneously. A confluence is defined between the threaded parts (521) of each screw rotor (52) and corresponds to the outlet (512) of the...
