Feed pump closure Overview: 
 Material sealed pump is a new type of powder pneumatic conveying equipment, low-pressure dilute phase pneumatic conveying conveying powder materials, the use of the entrainment effect of the high-speed airflow to transport powdered materials. Apply to fly ash, cement, cement raw material, slag and other transportation. The pipeline can be arranged depending on terrain, centralized, decentralized, large high degree of long-distance transmission, transmission process not affected by weather conditions, to ensure that the materials are not exposed to moisture, conducive to the production and environmental protection. Through the long-running practice, its stable performance, reliable quality, no dust pollution, which is ideal for pneumatic conveying equipment. 

 Material sealing the structure and working principle of the pump: 
 The seal material pump is mainly composed of four parts: namely, the nozzle, cylindrical pump, nozzles, adjusting device, the bottom of the vaporization device. Material to seal the pump work when the energy comes from two parts: one is the kinetic energy of the fan, another part of the column and the potential energy. Column material, potential energy, pressure, corresponding throughput, and vice versa small. 

 Material sealing the pump characteristics: 
 Material sealed pump a simple structure, simple operation, operating a small amount, can continuously send ash, can automatically adjust the output, good effect of conveying powder particles, transmission media pressure is low, equipment, pipe valves easy to wear; low-cost equipment less wearing parts, the entire transportation system performance and stability, one-time installation, debugging, the latter is basically no maintenance amount. 



 Material sealed pump works: 
 Seal material pump is the use of air jet effect, so that the air-driven ash particles of ash sent to Ash, material sealed pumps are mainly composed of four parts, respectively, for the nozzle, cylindrical pump, nozzles, adjusting device, the bottom of the vaporization device, material sealed pump work when the energy comes from two parts: one is the kinetic energy of the fans, another part of the column and the potential energy. Column material, potential energy, pressure, corresponding throughput, and vice versa small. Normal working hours of material sealed pump to maintain a certain level height, when the feeding amount increased in a short period of time ESP material sealed pump still work properly level a high degree of natural increase in pressure increased with the level of highly improved material trend can increase the throughput of the corresponding large until the system is self-balancing, when the feeding amount to reduce a short period of time ESP material sealed pump is still working properly level a high degree of natural lower, with the level height of the lower material to reduce the potential to reduce transportation correspondingly small until the system is automatically balanced. 



 I plant development and production of LFB-1 material sealed pumps, wind down, simple operation, small amount of maintenance and so on, are widely used in electric power, cement, chemical and other industries, is the ideal equipment for conveying various powder materials. Gongyi City, Fu Shing Machinery Factory, the production of low-pressure pneumatic conveying equipment has been 20 years of experience, the production of low-pressure pneumatic conveying equipment - material sealed pumps sold at home and abroad, the majority of users.
