Why does the initial operation of the pipe chain conveyor need a break-in period?

In the early stage of operation,pipe chain conveyorAfter a one-month running-in period, the running-in period is mainly divided into the following stages: it is required to check the pipe chain every day for one week, if the chain is found to be loose, it should be tightened immediately; check the chain in the pipe every day for two consecutive weeks. If the chain is found to be loose, it should be tightened. If there is wear, first find out the cause of the fault. After three or four weeks, check twice a week. Pay attention to wear. If the damage is severe, find out the cause first. After replacement, check once a week to ensure that the chain is tight and the equipment operates normally.
In the design of the pipe chain conveyor, the strength check of the conveyor belt is usually based on the static tension during operation, and the safety factor is set by considering the influence of other factors. The main factors of the strength of the conveyor belt of the pipe chain conveyor are as follows:
1. Static is the guarantee of the stable working tension of the mesh belt conveyor. When the same tension exists inside the mesh belt, the tensile stress caused by the static tension in the mesh belt is evenly distributed. With the operation of the mesh belt, alternating tensile stress will be generated, which is the basis for selecting the strength of the mesh belt.
2. Dynamic tension is the braking of the mesh belt. The velocity of each particle, the transport speed of the tube chain, the tension and the perturbations are of a dynamic nature and are a function of time.
3. Additional stress The additional stress of the mesh belt includes: the bending stress of bypassing the drum, the additional stress through the transition section, and the additional stress generated in the vertical and horizontal bending section. In engineering design, as long as the diameter of the roller, the spacing and shape of the transition roller and the bending radius of the mesh belt conveyor are accurately selected, these additional stresses can be greatly reduced, and manufacturing errors or coal powder bonding can cause the stress redistribution of the mesh belt.
In recent years, with the transformation of the national economy and the continuous changes in the market, due to the limitations of technical design, the past conveying equipment can no longer meet the needs of the future market. From a lot of known information, the food, pharmaceutical and other industries have transportation needs for various bulk materials such as powder, gypsum, small particles, small pieces, etc. Due to production technology and other reasons. In the past, the transportation equipment did not have the ability to continuously transport various materials.
Coal, construction and other industries attach great importance to transportation efficiency, but in the past, the design concept of transportation equipment was too complex and the transportation system was not stable enough. Even if the equipment runs at high power, it is difficult to achieve the expected transmission efficiency. Like some chemical fertilizer manufacturing enterprises, the working environment is special, and there are special requirements for the conveying distance, conveying direction and conveying height of the conveying equipment, and even the material conveying process is required to ensure pollution prevention and environmental protection.
How to successfully solve this series of problems will determine the development direction of transportation equipment in the future. The conveying system of the pipe chain conveyor can be composed of one or more pipe chain machines, including horizontal conveying pipe chain machines, inclined conveying pipe chain machines and vertical conveying pipe chain machines. The pipe chain conveyor is usually composed of a driving device, a tensioning device, a steering gear, a conveying pipe, a conveying chain and a control system.
The pipe chain conveyor adopts advanced closed-circuit pipeline transportation, which has stable performance, energy saving and environmental protection, and is durable. The pipe chain conveyor is driven by a chain to complete the entire conveying process. This conveying method ensures that the equipment can continuously convey powder, paste, small particles, small pieces and other bulk materials.
In addition, the device has a simple structure and low energy consumption. Under the same energy consumption, the conveying capacity can reach 300 m/h and the working efficiency is high.pipe chain conveyorWidely used in chemical, chemical fiber, pesticide, ore, food, feed, building materials and other industries. Different industries have different materials and different transportation requirements, so non-standard customization is particularly important. Different customers have different requirements for conveying distance, and the conveying length will be different.
