Ceramic Lined Elbow
AV Pump is a piece of equipment specially designed for use in pneumatic conveying systems. It uses compressed air as a power source to achieve efficient transmission of materials. AV pumps are particularly suitable for intermittent or continuous powder and granular material transportation tasks. They have the characteristics of simple structure, convenient operation, and low maintenance costs.
Principle
The working principle of ceramic lined wear-resistant elbow is based on its structural characteristics: 
Ceramic lining: Made of high-temperature sintered aluminum oxide (Al₂O₃), silicon carbide (SiC) and other ceramic materials. These materials have extremely high hardness and wear resistance.
Metal Casing: The exterior is constructed of steel or other metal to provide mechanical strength and support, ensuring that the elbow can withstand the pressure and temperature conditions of the conveyor system.
Seamless bonding: The ceramic layer and the metal shell are firmly bonded through a special process, avoiding cracks or falling off problems that may be caused by traditional welding methods.When the high-speed airflow containing solid particles passes through the elbow, due to the existence of the ceramic layer, even if the material hits the inner wall of the elbow at a high speed, it is difficult to cause significant wear to it. Therefore, the ceramic-lined wear-resistant elbow can maintain good sealing and smoothness during long-term operation, reducing the risk of leakage and frequency of repairs due to wear.Parameter
Features and Advantages
Super wear resistance: Ceramic materials have extremely high hardness and can effectively resist material impact and friction, significantly extending service life.
Low maintenance costs: Reduced replacement frequency due to wear and tear, reducing long-term operating costs.Excellent sealing: the ceramic layer is tightly combined with the metal shell to prevent material leakage and ensure the airtightness of the system.
Strong adaptability: It can handle various types of materials and is not affected by the humidity and viscosity of the materials. It is especially suitable for fragile or sensitive materials.
High temperature stability: It can work stably in a wide temperature range and is suitable for various harsh working conditions.
Optimize flow path: Reasonable bending radius design helps reduce flow resistance and energy consumption.
Good environmental performance: closed conveying avoids flying dust and reduces environmental pollution.
Easy to install and maintain: The compact design makes it easy to integrate into existing pipelines and facilitate maintenance.Usage Scenarios
Ceramic-lined wear-resistant elbows are widely used in all aspects of pneumatic conveying systems, especially where large amounts of powder or granular materials need to be transported over long distances and at high lifts. The following are several typical application scenarios:- Building materials
