(Summary description) Theoretically speaking, any place where objects touch and generate friction will cause wear, especially the inner wall of the pneumatic conveying pipeline. If the pneumatic conveying is not properly selected, the excessively fast wind speed and the material with higher hardness will easily shorten the life of the pipeline. Different parts or materials can withstand wear for different lengths of time. Since wear is unavoidable in pneumatic conveying, can some design techniques be used to reduce pipeline wear?   防止磨损的措施包括防磨和耐磨。处理磨损问题可采取以下相关技术措施: 1. 在确保管内粉尘可以正常运输的前提下,尽量控制管内风速。根据物料特性,选择合适的输送方式以及输送风速,避免由于过大风速而造成物料对管壁的磨损。 2. 优化管道设计,选用合适的弯头曲率半径,并在弯头处适当增加壁厚l~2mm。 3. 气力输送过程中,对管道弯头处的磨损最大,为了减少管道磨损对生产造成的影响,在设计过程中我们对弯头处进行特殊的设计来延长管道的使用寿命,降低气力输送管道的磨损。   采用较多的有背包式弯头,通过增设填充腔,减少物料对弯头处的磨损,使弯头的使用周期大大增加,减少更换和修补耐磨弯头的次数。 另外还有选用耐磨衬里的特殊弯头,如陶瓷耐磨弯头、耐磨涂层弯头等。宏工选用较多的是陶瓷耐磨弯头,由于锂电行业的物料不能与铜锌铁等接触,因此陶瓷弯头相比起其他涂层有较大的优势,能有效增加管道的耐磨强度,延长使用寿命。

Theoretically speaking, any place where objects touch and generate friction will cause wear, especially the inner wall of the pneumatic conveying pipeline. If the pneumatic conveying is not properly selected, the excessively fast wind speed and the material with higher hardness will easily shorten the life of the pipeline. Different parts or materials can withstand wear for different lengths of time. Since wear is unavoidable in pneumatic conveying, can some design techniques be used to reduce pipeline wear?

Measures to prevent wear include anti-wear and wear-resistant. The following related technical measures can be taken to deal with the wear problem:

1. On the premise that the dust in the pipe can be transported normally, try to control the wind speed in the pipe. According to the characteristics of the material, select the appropriate conveying method and conveying wind speed to avoid the wear of the material on the pipe wall due to the excessive wind speed.

2. Optimize the pipeline design, select the appropriate curvature radius of the elbow, and appropriately increase the wall thickness at the elbow by 1 ~ 2mm.

3. In the process of pneumatic conveying, the wear at the elbow of the pipeline is the largest. In order to reduce the impact of pipeline wear on production, we have specially designed the elbow during the design process to prolong the service life of the pipeline and reduce the pneumatic conveying pipeline. of wear.

More backpack-type elbows are used, and by adding a filling cavity, the wear of the material on the elbow is reduced, the service cycle of the elbow is greatly increased, and the number of replacement and repair of the wear-resistant elbow is reduced.

In addition, there are special elbows with wear-resistant linings, such as ceramic wear-resistant elbows, wear-resistant coated elbows, etc. Honggong chooses more ceramic wear-resistant elbows. Since the materials in the lithium battery industry cannot be in contact with copper, zinc, iron, etc., ceramic elbows have greater advantages compared with other coatings, which can effectively increase the wear-resistant strength of the pipeline. ,Extended service life.
