Abstract
The invention discloses a rib antifriction elbow pipe which can be applied to the concrete pumping system; ribs are arranged on the inner wall of the external side; the ribs are distributed on the inner wall in the angle of 15 degrees to 75 degrees on the external side of the elbow pipe with equal intervals; the cross section of each rib can be a square or a trapezoid. The ribs are arranged on the inner wall of the rib antifriction bent pipe to improve the antifriction performance and the service life of the elbow pipe.
Description
Technical field
The invention belongs to engineering machinery, relate to bend pipe, be particularly useful for the rib abrasion-resistant elbow of concrete pumping system.
Background technique
In engineering machinery field and field of petroleum exploitation, line transportation is the transportation logistics scheme of a quickness and high efficiency.Because the particularity of industry, employed pipe-line equipment is all relatively being worked under the exacting terms mostly in such industry.So very serious of the loss situation of such pipeline caused very big cost allowance and waste in actual production.
For the concrete mixer in the engineering machinery, it is the visual plant in the high-building construction process.The bend pipe damage is an a great problem in the transmission and concrete transmission.Owing to the loss that the breakage of bend pipe causes is also quite huge, be to prolong pipeline life, improve Security, the main at present method of using is to seek wear-resisting high hardness material, by improving the wear resistance and the hardness of material itself, the life-span of improving bend pipe.
Though the use of new material can improve the life-span of pipeline to a certain extent, new material itself also has the narrow limitation of its more high aspect of cost.The present invention mainly is by the design method of improvement pipe-line system, gives its guiding design method from pipeline configuration, thereby improves under situation cheaply the working life of pipe-line system.
Summary of the invention
The object of the present invention is to provide a kind of rib abrasion-resistant elbow that can be used for concrete pumping system,, improve the working life of bend pipe under the solid multiphase flow condition of high-pressure spray by adding rib at elbow internal wall.
For reaching above purpose, solution of the present invention is:
A kind of rib abrasion-resistant elbow that can be used for concrete pumping system, the inwall in its outside is provided with rib.
Further, this rib is distributed in the bend pipe outside 15 degree to the inwall of 75 degree.
This rib is equidistantly to distribute.
This rib is 6-12.
The length of this rib is for striding 90 degree semicircles, width and highly be the 1/4-1/15 of bend pipe diameter.
The cross section of this rib is a square.
The cross section of this rib is trapezoidal.
The ratio of going to the bottom on this is trapezoidal is 4/5-2/5.
Owing to adopted such scheme, the present invention to have following characteristics: the present invention has added rib at elbow internal wall, has improved its wear resistance, has increased working life, and it is simple in structure, cost is low, has good practicability.

Embodiment
The present invention is further illustrated below in conjunction with the accompanying drawing illustrated embodiment.
The present invention is directed to the solid bend pipe of multiphase flow under the high-pressure delivery condition of stream and carry out structural improvement.Find the main cause of pipe wear mechanism by the combination research of finite element simulation simulation and a plurality of erosive wear models, and bend pipe structure is redesigned according to pipe wear mechanism, final by changing the design of bend pipe structure, improve bend pipe in the working life of flowing under the solid multiphase flow high-pressure delivery condition.
As Fig. 1-shown in Figure 4, the present invention is provided with rib 2 at bend pipe 1 inwall, and its method that rib is set on mould during by casting realizes.Rib 2 is traditionally arranged to be 6 to 12, is evenly distributed in bend pipe 1 outside 15 degree to the inwall of 75 degree.Its length is striden 90 degree semicircles, width and highly be the bend pipe diameter 1/4 to 1/15 between, sectional shape is square (as Fig. 1) or trapezoidal (as Fig. 4), the ratio of going to the bottom on trapezoidal is 4/5-2/5.
The present invention is that example is tried out with 37 meters concrete mixers of 31 heavy industrys, and bend pipe can play good anti-wear effect after being installed in this concrete pumping system really, and the life-span also improves greatly.
The above-mentioned description to embodiment is can understand and apply the invention for ease of those skilled in the art.The person skilled in the art obviously can easily make various modifications to these embodiments, and needn't pass through performing creative labour being applied among other embodiments in the General Principle of this explanation.Therefore, the invention is not restricted to the embodiment here, those skilled in the art should be within protection scope of the present invention for improvement and modification that the present invention makes according to announcement of the present invention.
