Abstract
The utility model relates to a wear-resistant corundum ceramic elbow for a concrete pump truck. The wear-resistant corundum ceramic elbow comprises a steel pipe body, wherein the two ends of the steel pipe body are provided with steps; a plurality of grooves are distributed on the inner wall of the steel pipe body; ceramic chips are stuck in the grooves positioned at the two ends; and a variable-diameter ceramic chip is stuck in the groove at the middle part. An included angle between two linear edges of each ceramic piece and the variable-diameter ceramic chip is 10 degrees. The wear-resistant corundum ceramic elbow has the beneficial effects of having the characteristics of compact composition and wear resistance and prolonging the service life of the elbow by multiple times compared with that of the prior art.
Description
Technical field
The utility model relates to the automobile-used abrasion-resistant corundum ceramics elbow of a kind of concrete pump.
Background technology
To receive the erosion effect of concrete mix in the long-term use of concrete mixer pipeline.Especially pipeline connecting bend place produces huge centrifugal action because of the concrete mix direction of motion changes, and the impact abrasion that bear in elbow external diameter place is the most serious, even worn out, and the elbow wear rate is higher than the straight sections figure place doubly.The employing that available coagulation soil pump truck elbow of pipeline has increases the pipeline inner wall metal thickness, and the employing wear resistant alloy material that has is increasing the service life, but cost is high, and effect is ideal not to the utmost.
The utility model content
The purpose of the utility model provides the automobile-used abrasion-resistant corundum ceramics elbow of a kind of concrete pump, to overcome the above-mentioned deficiency that exists in the prior art.
The purpose of the utility model is to realize through following technical scheme:
The automobile-used abrasion-resistant corundum ceramics elbow of a kind of concrete pump comprises steel tube body, and the two ends of steel tube body are provided with step, the inwall of steel tube body some grooves that distribute, and the groove that is positioned at two ends is stained with potsherd, is stained with the reducing potsherd in the groove of mid portion.
The angle of two straight lines of described potsherd and reducing potsherd is 10 degree.
The beneficial effect of the utility model is: have combination closely, wear-resisting characteristics compared with prior art, can prolong the several times in application life of elbow.
Description of drawings
According to accompanying drawing the utility model is done further explain below.
Fig. 1 is the structural representation of the plastics main casing of the automobile-used abrasion-resistant corundum ceramics elbow of the described concrete pump of the utility model embodiment.
Among the figure:
1, steel tube body; 2, step; 3, potsherd; 4, reducing potsherd.
The specific embodiment
As shown in Figure 1; The automobile-used abrasion-resistant corundum ceramics elbow of the described a kind of concrete pump of the utility model embodiment; Comprise steel tube body 1, the two ends of steel tube body 1 are provided with step 2, the inwall of steel tube body 1 some grooves that distribute; The groove that is positioned at two ends is stained with potsherd 3, is stained with reducing potsherd 4 in the groove of mid portion.The angle of two straight lines of described potsherd 3 and reducing potsherd 4 is 10 degree.
During concrete the use; Spread corundum ceramic one time at concrete mixer elbow steel pipe inwall; Because in the concrete mix course of conveying, because the impact grinding degree of corrosion that the centrifugal action that the elbow concrete mix produces makes the utility model outer radius bear is big, the increase of elbow outer radius corundum ceramic piece thickness can guarantee to improve elbow application life; And practice thrift the corundum ceramic use amount, and can alleviate elbow weight.
Claims (2)
