Importance of Pneumatic Conveying Equipment for Leakproofness and Requirements for Piping Arrangement
2019-09-09 Source: wglobalnba.com Author: Rich Machinery read: Times
With the continuous progress of people, the pace of industrial development is getting faster and faster. The age of manual material transportation has passed. The earlier pneumatic conveying method was mechanical conveying, and then transitioned to the warehouse pump. Until now, the low-pressure ash conveying equipment .
In practical operation of pneumatic conveying equipment, in most cases, it is required to be transported in succession. Successive transport will improve the incidence of faults. In order to reduce the frequency of faults, attention should be paid to some issues during use. First of all, we must understand that the low-pressure transport pump is a low-pressure system composed of successive pumps. This system is very reliable and can not be compared with any other transport equipment. Because this system mostly uses Roots fans, Roots on the market The reliability of the fan is very strong, and then the reliability of the pneumatic conveying system is determined. However, the types and quantities of such equipment are not many, so the whole system looks very simple and reliable, and it is very stable in a continuous operation state without any impact load. Because it does not operate the valve frequently like the conventional pneumatic conveying process, it can be useful to reduce problems.

Pipe leakage is also a common problem. Therefore, when manufacturers produce pneumatic conveying equipment, they use seamless steel pipes with high wear resistance. However, after long-term use, they will still leak due to boring wear and tear, and may be blocked. This phenomenon is mainly reflected in the following aspects. When the elbow part is in operation, it will cause leakage due to touching and wearing with other external equipment. If the ash discharge door is not tightly closed, it will also cause blood pressure short circuit. The seal ring may not be installed properly during installation. Looseness, these reasons will cause the pipeline to leak. Leakage in the pipeline will cause tube blocking and lack of reasoning, and the pressure at the leakage point will be reduced, so special precautions need to be taken to prevent the leakage of pneumatic transportation pipelines.
When arranging the conveying pipeline, pay attention to the following points: 1. The pipeline must be as short as possible under the premise of meeting the transportation requirements. 2. Minimize the number of elbows. 3. Avoid connecting the two elbows closer. If the two elbows are close together, it may happen that the material has decelerated in one elbow before it has time to accelerate, and then enters the next elbow, causing the material to further decelerate, causing a pipe plugging phenomenon, and the distance between the two elbows. It must be at least 40 times the diameter of the pipe and use a bend with a large bending radius. 4. The horizontal pipe should not be too long. The material is conveyed in the horizontal pipe, and the deposition phenomenon will gradually appear. The installation of elbows or plumbing pipes in the middle can stir the material that has just started to be deposited, making the material transportation easier. If the conveying distance is too long, consider installing Booster device.
