What Is the Pipe Making Process Principle of the Suspended Roller Concrete Pipe Making Machine?

The suspended roller concrete pipe making machine has a simple structure and is easy to operate. It uses dry hard concrete to make pipes. It has a low water-cement ratio, low cement consumption, no stratification or water seepage on the pipe wall, is homogeneous and dense, and has good anti-seepage performance. It is a very efficient equipment. It has been promoted since its launch and is still one of the most advanced and widely used important methods for concrete pipe making. Before choosing this pipe making machine, you may be curious about its specific process principle. Let's learn about the suspended roller concrete pipe making machine.

First of all, the pipe mold is a combination of the mold body and the steel rings (retaining rings) at both ends suspended on the suspension roller shaft, while the roller shaft is an X-shaped shaft on the suspension roller machine, which is driven by the motor and transmission system. The steel mold is driven by friction between the retaining ring and the suspension roller oil, and rotates with the suspension roller shaft. The retaining ring also controls the wall thickness of the pipe to be formed.

When the suspended roller is used to make pipes, the suspended roller shaft rotates and frictionally transmits with the retaining rings at both ends of the pipe mold, driving the pipe mold to rotate. The pipe mold is equivalent to the drum of an industrial centrifuge. At this time, concrete is added, and the concrete is the material attached to the pipe mold. The pipe mold generates centrifugal force at a certain speed. When the concrete is subjected to a certain centrifugal acceleration, it is enriched on the inner wall of the pipe mold until the thickness is required by the process. This is the feeding process of the suspended roller concrete pipe making machine, also known as the centrifugal feeding process.

Under the action of centrifugal force, the concrete material is added to exceed the inner circular surface of the retaining ring. At this time, the main contact with the roller shaft is concrete. Pressure is generated between the roller shaft and the concrete, which is the roller pressure. In the process of further increasing the angular velocity of the steel mold, the reaction force (roller pressure) of the roller shaft on the concrete + increases accordingly, and the pipe is compacted.

In the process of spreading and rolling, due to the uneven distribution of concrete material, the vibration caused by the inconsistent contact between the roller shaft and the concrete material, this vibration force helps to spread the material evenly and increase the effect of vibration and compaction.

Through these steps, we can see the entire production process. When the suspended roller concrete pipe making machine is working, the suspension roller shaft rotates at a certain speed driven by the motor, and the pipe mold suspended on the shaft is driven to rotate by the friction between the retaining ring and the suspension roller shaft. The concrete material added to the pipe mold adheres to the inner wall of the pipe mold under the action of centrifugation. When the thickness of the input concrete material exceeds the inner diameter of the pipe mold retaining ring, it is subjected to the roller pressure of the suspension roller shaft and gradually becomes dense to form a tube wall. The pipe making process of compacting concrete under the triple action of centrifugation, roller pressure and vibration is the working principle of the suspended roller concrete pipe making machine.
