Embodiment

[0030] Embodiment: undulating living tongue constant flow pump as attached Figure 4-5 As shown, it includes a stator, a rotor, and a suction and discharge port. Its main feature is that one end of the disc-shaped rotor 3 with a movable tongue 4 is installed on the inner bearing of the oblate cylindrical stator 2 with a filling block 5, and the other end protrudes from the flat cylinder. Cylindrical stator 2 is connected to the motor outside the shell (not shown in the figure), and semi-cylindrical filling blocks 5 are arranged symmetrically on the upper left and lower right inside the stator. The stator 2 surrounds an up and down circular track.

[0031] In the embodiment, on the radius of the disk-shaped rotor 3, two movable tongue holes are distributed axisymmetrically, and the movable tongue 4 is installed in the hole. Push the lower shaft to slide freely and move up and down on the circular track.

[0032] In the embodiment, the semi-cylindrical filler block 5 inside th...

Abstract

The present invention aims to provide a constant-flow pump with high constant-flow performance and no one-way sealing member. It specifically relates to an undulating movable tongue constant flow pump, including a stator, a rotor, and a suction and discharge port, and is characterized in that one end of the disc-shaped rotor shaft with a movable tongue is installed on the inner bearing of a flat cylinder stator with a filling block, and the other end extends Out of the oblate cylindrical stator shell, it is connected with the motor, and the upper left and lower right of the stator are symmetrically arranged with semi-cylindrical filling blocks. The diameter section of the filling block is composed of tangential smooth surfaces, and forms an up and down circular track with the oblate cylindrical stator. . The undulating movable tongue constant flow pump of the present invention has high constant flow performance, does not need expensive one-way sealing components, and can be widely used in production and life, especially in the fields of chemical production and scientific research.

Description

technical field [0001] The invention belongs to the field of metering pumps, in particular to a constant-flow pump with undulating movable tongues. Background technique [0002] The plunger type constant flow pump is one of the most widely used machines in production and life, especially in chemical production and scientific research. However, the intermittent nature of the plunger movement is the defect in its use; the one-way sealing requirements of the suction and discharge ports are high, and gem materials are usually required, and the failure rate is high and the cost is high. Contents of the invention [0003] The present invention aims to provide a constant-flow pump with high constant-flow performance and no one-way sealing member. In particular, it relates to a constant flow pump with undulating movable tongue. [0004] The design idea adopted by the present invention to solve the technical problem is: abandon the piston structure, design a brand-new undulating ...
