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 shell, a stator and a rotor, wherein the stator and the rotor are coaxially installed in the shell; the stator is fixedly connected with the shell; a radial gap is formed between the rotor and the stator; the top of the shell is provided with a top flange and a first through hole, the bottom of the shell is provided with a bottom flange and a second through hole, and the middle of the shell is provided with a third through hole; the stator is provided with at least two ribs and a stepped hole; an included angle of 90-150 degrees is formed between the first surface and the second surface at the two sides of each rib, and the ribs form a step-shaped structure on the inner circumferential surface of the stator; the curvature of the second surface is greater than the radial curvature of the rotor; a gap is formed in the second surface and forms an opening of the stepped hole; and the stepped hole is communicated with an annular inner cavity and an outer cavity. The rotor pump can overcome the defects that an existing pump is large in friction loss, large in noise, large in vibration and the like, and meanwhile, switching between a positive pressure pump and a negative pressure pump can be achieved through reversing of the rotor.
Description
technical field [0001] The invention relates to the technical field of general machinery, in particular to a non-contact adjustable rotor pump. Background technique [0002] A pump is a machine that transports liquid or pressurizes a fluid. According to the working principle, it can be divided into positive displacement pump, impeller pump and jet pump. The positive displacement pump relies on the movement of the working parts to cause the periodic increase and decrease of the working volume to absorb and discharge the liquid, and directly increases the pressure of the liquid by the extrusion of the working parts; according to the different structures of the moving parts, the positive displacement pump can be divided into two types: Piston pumps, plunger pumps, gear pumps, screw pumps, vane pumps and water ring pumps. The impeller pump is driven by the impeller to rotate the liquid at high speed to transfer the mechanical energy to the liquid being transported; according to...
