Example Embodiment

[0050] In order to make the purpose, technical implementation and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with specific examples.

[0051] The invention provides an adjustable shaftless pump, which consists of a shaftless pump body, a pump support, an ultrasonic velocity meter, a PLC controller, a manual screw rod, and a variable-diameter flange connected to the shaftless pump by a water passage. , the shaftless pump is electromagnetically driven by a shaftless motor.

[0052] The shaftless pump is mainly installed between the joints of the water pipeline or the turning of the pipeline. In the connection of the pipe network system, there will inevitably be local head loss between the pipe joints. Due to the water blocking effect of the head loss, the water flow rate is often the same. Compared with other parts of the pipeline, it is smaller. After installing this shaftless pump, it will pump wa...

Abstract

The invention provides a shaftless pump and a using method thereof. The shaftless pump comprises an outer ring, a middle ring, an inner ring, a plurality of arc-shaped blades, a plurality of support rods and guide cones, wherein circular bayonets are symmetrically formed in the upper part and the lower part of the outer ring; a U-shaped motor driving coil is arranged on the inner side of the middle ring and serves as a stator; the outer side of the middle ring is hinged to the circular bayonets of the outer ring through two cylindrical hinged pieces, and the outer side of the inner ring is connected with the middle ring through a positioning bearing and serves as a rotor; one end of each support rod is connected with the inner side wall of the inner ring, and the other end of each supportrod is connected with the corresponding guide cone in a supporting mode; the guide cones are positioned in the center of the inner ring; and the arc blades are connected to the middle parts of the corresponding support rods and are uniformly distributed to form an impeller. According to the shaftless pump, an internal middle ring and inner ring linking body of a rotary pump realizes blade expanding while running through a pipeline and operating a water pump; the blade is packed up when the water pump is closed or subjected to fault, so that the flushing of running water on the blade is reduced, and the service life is prolonged.

Description

technical field [0001] The invention relates to a water passage and a shaftless pump, in particular to a shaftless pump with adjustable blades and a method for using the same, belonging to the technical field of hydraulic engineering equipment and machinery. Background technique [0002] Water pump inlet and outlet channels, household heating and heating pipes, and water supply and drainage pipe networks generally have long pipelines and complex pipeline networks. Due to the existence of local head loss between pipeline connections, the internal flow state of the pipeline is unstable and the flow velocity is relatively small. Meet the water supply and drainage requirements. [0003] When the existing horizontal water pump is operated at a small flow rate lower than the rated flow rate, the efficiency of the pump is low; and the existence of the motor shaft will generate a lot of noise interference during operation, which will cause a kind of interference to the staff and als...
