Problems solved by technology
[0007] In view of this, the present invention provides a non-contact adjustable rotor pump, which can be used as a conveying pump or a vacuum pump. There is a gap between the stator and the rotor during operation, which can solve the problem of existing pumps. There are defects such as large friction loss, large noise, and large vibration. At the same time, the real-time switching between "positive pressure pump" and "negative pressure pump" can be realized by changing the rotation direction of the rotor.

The invention discloses a non-contact adjustable rotor pump. The rotor pump comprises a housing, a stator and a rotor; the stator and the rotor are coaxially installed in the housing; the stator is fixedly connected to the housing; clearance; the top of the housing is provided with a top flange and a first through hole, the bottom is provided with a bottom flange and a second through hole, and the middle is provided with a third through hole; the stator is provided with at least two ribs and stepped holes; the convex An included angle of 90° to 150° is formed between the first surface and the second surface on both sides of the rib, and the rib forms a stepped structure on the inner peripheral surface of the stator; the curvature of the second surface is greater than the radial curvature of the rotor; the second The surface is provided with a slit, and the slit forms the opening of the stepped hole; the stepped hole communicates with the annular inner cavity and the outer cavity. The rotor pump can solve the defects of the existing pumps such as large friction loss, large noise, and large vibration, and at the same time, the switch between "positive pressure pump" and "negative pressure pump" can be realized through the reversing of the rotor.
Description
Technical field [0001] The present invention relates to the field of general mechanical technology, specifically to a non-contact adjustable rotary lobe pump. Background [0002] Pump is a machine that transports liquid or pressurizes fluid, and can be divided into positive displacement pump, impeller pump and jet pump according to the working principle. Positive displacement pump is dependent on the movement of the working parts to cause the working volume to periodically increase and shrink and suction liquid, and rely on the extrusion of the working parts to directly increase the pressure of the liquid; according to the different structure of the moving parts, the positive displacement pump can be divided into piston pump, plunger pump, gear pump, screw pump, vane pump and water ring pump. Impeller pump is based on the impeller to drive the liquid high-speed rotation and the mechanical energy is transferred to the transported liquid; according to the different characteristics...
