Abstract

Disclosed is a small-flow single-shaft forward and reverse screw extrusion type magnetic driving pump. The invention relates to the technical field of flow pumps. A direct current speed regulating motor is fixed on a fixed base; an output end of an output shaft of the direct current speed regulating motor is connected to magnetic coupling external magnetic steel; the direct current speed regulating motor is connected to a magnetic coupling shielding cover by virtue of a motor connecting flange; the magnetic coupling shielding cover is connected to the end part of a stator seat by virtue of bolts; the magnetic coupling external magnetic steel is arranged outside the magnetic coupling shielding cover in a covering manner; magnetic coupling internal magnetic steel is movably embedded in the magnetic coupling shielding cover; a screw shaft is arranged in the stator seat; and the front end of the screw shaft is in screwed connection with the front end wall of the stator seat by virtue of afront bearing. The small-flow single-shaft forward and reverse screw extrusion type magnetic driving pump can realize the operation with no leakage, low noise, stable flow and stable pressure output.

Description

technical field [0001] The invention relates to the technical field of flow pumps, in particular to a small-flow uniaxial positive and negative screw extrusion type magnetic drive pump. Background technique [0002] With the improvement of people's awareness of environmental protection, the use of new energy-saving steam heat source machines has become more and more. The working hours are getting longer and longer, and the temperature inside the steam heat source machine is getting higher and higher. The main component of the steam heat source machine is the water pump, which not only has to withstand high temperature and high pressure, but also has to work for a long time. Therefore, it is necessary to ensure that the water pump is in normal condition to ensure the heat source. stable operation of the machine. [0003] At present, the water pump of the steam heat source machine often leaks, the water flow and pressure are not in order, and there are many faults, which affe...
