Henan rich manufacturing materials closure pump hoist, screw conveyor, saving 80-98% of parts and maintenance costs, and has a simple structure, easy maintenance, etc.; material sealed pumps with small size, the wind pressure, reliable operation, almost no wearing parts and many other advantages. Material sealed pump delivery of materials 3-500M, lifting height up to 50M, material sealed pump is a comprehensive, cost-effective professional equipment for conveying powder materials. The seal material pump can be used: thermal power, cement, fly ash, lime, gypsum powder, fine chemical production and use of materials than ≤ 1.6 the following companies. 

 Fu into a pneumatic conveying material sealed pump in the domestic 
 Henan rich pneumatic conveying material to seal the pump and power plants work alongside grand new development, the material sealed pump in the Shandong region best, Sichuan, Shanxi, Guizhou, Yunnan and also has good application, pneumatic conveying material sealed pump manufacturers across the country, large and small power plants, cement plants and other needs of pneumatic conveying are common, but used a single-chamber pump, we will introduce in the back to use the specific advantages of the material sealed pump more than a single-chamber pump material seal pumping requirements material seal pump according to the specific circumstances of the thermal power plants, thermal power plant pneumatic ash handling system layout into a single pump single-tube or pump condominium, multi-pump air source type. 

 Pneumatic conveying material sealed pump internal velocity is low and constant, and thus wear a small, long service life makes the whole material seal pump system equipment. Material sealed pump sump pumps the advantages of a material seal pump can replace two sump pumps, reducing equipment investment. Material sealed pump wear and tear than the sump pumps pipes, conducive to the normal run of the sediment pool, improve the production environment, conducive to the fly ash applied again. Sump pumps operating complex material sealed pump easy to operate, and a one-time put into operation without repair, sump pumps power consumption, due to low air pressure, the material sealed pump so relatively speaking, than the sump pumps more energy efficient. 

 Seal material pump pipe can be horizontal, vertical, oblique arrangement, to meet the thermal power plants, thermal power plant pneumatic ash handling system ever-changing layout requirements. Material sealed pump works material sealed pump powdered materials by atmospheric pressure into the pump in the use of the unique design of the injection device, the powder material into the pipeline, the use of gas beat errand sent by the fly ash along the pipeline expected destination. Material sealed pump due to the continuous transport of low-voltage wind capacity, external substances can not enter the tube material sealed pump does not exist in the process of running the plugging phenomenon, and will not change the physical properties of the materials. 

 Production material sealed pump, pneumatic conveying material sealed pump manufacturers around the country is not much, Gongyi City, mostly. Gongyi City is a major industrial counties. Henan rich company to stand out in a number of manufacturers, can be described as objects compete for the rich into the survival of the fittest. 




 Material sealed pump drain Note: 

 : Due to the low-speed bolt slug flow pneumatic conveying system for material sealed pump in the general case, a boiler need to configure two or more pipelines, hence, have is blown counter, dredge the condition of the plumbing fixtures, The closure of the material pump device than to qi ring to clear the conveying pipeline effect, and dredge the speed. 
 : Air is blown butterfly valve, pneumatic counter, ball valves and pipeline pressure switch composed of dredge pipeline installations, the use of a PLC program control set in the pipeline starting end. 
 : When the transmission pipeline pressure switch ultra-high output signal, turn off the L-type sump pumps air intake valve, open the ball valve pneumatic counter, using the negative pressure in the rear of the boiler flue counter, the pipeline dry ash, counter, 30s. At this point, if the transport pipeline pressure is still not down to normal, turn off the counter, pneumatic ball valve, open the pneumatic blowing is a butterfly valve, conveying compressed air to pressurize the pipeline, is blowing time of 90s counter, is blowing a repeated action, until the pressure within the pipeline back to normal, by the transmission pipeline pressure switch output signal, an automatic discharge of dredge pipeline procedures, and pump the normal operation of the program to restore L-type positions. 
 4: transportation system during normal operation, the pneumatic blowing is the butterfly valve, pneumatic counter, ball valve is turned off. 


 Of LFB-I-type material sealed pump is my factory based on the introduction of foreign advanced technology for domestic different types of pneumatic conveying equipment, the existence of a variety of problems and building materials School of cooperation while developed out of the new low-pressure air force conveying pump, the product widely applicable in electricity ash, cement and oriented and down the library, all kinds of powder materials transportation, high efficiency and low consumption, fully enclosed, no pollution, no maintenance, the gas source can be used a Roots blower, compressed air.
