Technical Field

The invention relates to the technical field of screw pumps, in particular to a single-screw pump capable of preventing material blockage.

Background

The single screw pump belongs to a rotor type displacement pump, and is characterized by that the screw and lining are mutually meshed to produce volume change in suction cavity and discharge cavity to transfer liquid. The main working parts of the internal engaged closed screw pump are composed of a lining (stator) with a double-head spiral cavity and a single-head spiral screw (rotor) engaged with the lining in the stator cavity. When the input shaft drives the rotor to make planetary rotation around the stator center by means of universal joint, the stator-rotor pair are continuously meshed to form sealed cavities, these sealed cavities can make constant-speed axial movement, and can be used for conveying medium from suction end to discharge end, and the medium sucked into the sealed cavity can be passed through the stator, and can not be stirred and damaged. Classifying the single-screw pump: the integral stainless steel single-screw pump and the shaft stainless steel single-screw pump. When the existing single-screw pump works, a material blocking phenomenon can be generated, the whole device is greatly influenced, and a large amount of manpower and material resources can be consumed for dredging.

To this end, we propose a single screw pump to prevent the blocking to solve the above problems.
