Technical Field
The invention relates to the technical field of pipelines, in particular to a conveying pipe and pumping equipment.
Background
At present, a conveying pipe is a pipe fitting used for conveying fluid materials by pumping equipment, and is commonly used for conveying thick materials containing particulate matters, such as concrete. In the transportation process, the particle in the viscous material easily produces friction or collision with the inner wall of pipeline, especially in return bend department, the conveyer pipe receives the impact force of concrete great, can accelerate the wearing and tearing of return bend department to the life of conveyer pipe has been shortened. Wherein, for the inboard of return bend, the outside that receives of return bend is great for the impact, and concrete mortar easily causes the wearing and tearing of the outside portion of return bend and even breaks in the pumping process, influences the overall reliability of conveyer pipe. Some improvements are made to a conveying pipe for concrete pumping equipment in the prior art, the wear resistance of the conveying pipe is improved by improving the structure or the material of the conveying pipe, for example, the material of the conveying pipe is changed, the thickness of the outer side of an elbow pipe is increased, a double-layer elbow pipe is improved or a wear-resisting plate is additionally arranged, and the like.
Disclosure of Invention
The present invention is directed to improving at least one of the technical problems of the prior art or the related art.
To this end, it is an object of the present invention to provide a delivery pipe.
It is another object of the present invention to provide a pumping apparatus.
In order to achieve the above object, a first aspect of the present invention provides a delivery pipe, including: a pipe body; the plurality of bosses are arranged on at least part of the inner wall surface of the pipe body, extend along the axial direction of the pipe body and are arranged at intervals along the circumferential direction of the pipe body; and the diversion trench is formed between two adjacent bosses.
According to the technical scheme of the first aspect of the invention, the conveying pipe comprises a pipe body, a plurality of bosses and a diversion trench. Through being equipped with a plurality of bosss on at least partial internal face at the body, the boss extends along the axial of body, and a plurality of bosss set up along the circumferential direction interval of body, make form the guiding gutter between two adjacent bosss, make at least partial inner wall of body form concave-convex structure, separate the fluid that flows through the body through the boss, and lead through the guiding gutter fluid, guide the axial direction flow of fluid along the body, reduce the fluid and flow along the possibility of circumference, fluid flow accelerates. Especially when the conveying pipe is used for conveying special fluids such as concrete mortar, the boss guides the concrete mortar to bear partial impact force and friction force, so that the impact and abrasion of the concrete mortar to the pipe body can be relieved, the strength of the pipe body is improved, the failure rate is reduced, and the service life is prolonged. Specifically, the cross-sectional shape of the boss may be a round-bottom trapezoid, and the size of one end of the round-bottom trapezoid, which is close to the inner wall surface of the pipe body, is greater than the size of one end of the inner wall surface, which is far away from the pipe body, and accordingly, the cross-section of the diversion trench between two adjacent bosses forms a round-bottom trapezoid shape, that is, the distance between two side walls of the diversion trench is gradually increased inwards along the radial direction of the pipe body, so as to increase the volume of the fluid which can be.
The cross-sectional shape of the boss is not limited to the round-bottom trapezoid in the present embodiment, but may be a round-bottom rectangle or other shapes.
It should be emphasized that the boss may be provided at a partial position of the inner wall surface of the pipe body, or may be provided entirely along the circumferential direction of the pipe body.
In addition, the conveying pipe in the above technical solution provided by the present invention may further have the following additional technical features:
in the above technical solution, the delivery pipe further includes: the protruding structure is arranged on the bottom wall surface of the flow guide groove and comprises a plurality of point-shaped protrusions.
In this technical scheme, set up through the diapire face at the guiding gutter and include the bellied protruding structure of a plurality of punctiform, make the bottom wall face of guiding gutter form unsmooth undulation's structure, in order when the particulate matter contact with in the fluid, especially when contact with grit in the concrete mortar, can make sliding friction convert rolling friction into between particulate matter and the body, can reduce frictional resistance by a wide margin, and then reduce the wearing and tearing of particulate matter to the internal face of body, be favorable to improving the reliability and the life of conveyer pipe. The number and the size of the point-shaped bulges can be determined according to the size of the pipe body, and the point-shaped bulges can be continuously arranged or arranged at intervals.
It should be noted that the protruding structure may also be other shapes, such as rectangular, trapezoidal, or oval protruding structure.
In the above technical scheme, the pipe body is of a bent pipe structure.
In this technical scheme, be the return bend structure through injecing the body for the position that the fluid flow direction changed takes place, the boss through in the body leads to the fluid to make the particulate matter in the fluid form the roll through protruding structure, with when the fluid passes through the return bend structure, alleviate the impact force and the frictional force of the particulate matter of fluid to the return bend structure, play the guard action to the return bend.
In the technical scheme, the boss and the diversion trench are arranged on the inner wall surface of the outer pipe wall of the pipe body; or the lug boss and the diversion trench are arranged on the inner wall surface of the inner pipe wall of the pipe body and the inner wall surface of the outer pipe wall of the pipe body.
